Seonjin Environment (CEO Kang-woo Lee), a green technology company specializing in refrigerants and fluorinated compounds, announced that it received the Prime Minister's Commendation at the '2026 Environment Day' Merit Award Ceremony held on June 5.

The award was presented at the Environment Day ceremony hosted by the Ministry of Climate, Energy and Environment and organized by the Korea Environmental Preservation Institute. Seonjin Environment was recognized for its contributions to realizing carbon neutrality, such as reducing a cumulative 1.38 million tons of greenhouse gases through the establishment of a full-lifecycle management framework for F-gases (refrigerants and $SF6$ ) as well as high-purity purification and recycling technologies.

Established in 2013 at the Saenggok Industrial Complex in Gangseo-gu, Busan, Seonjin Environment became the first in the nation to complete its registration as a refrigerant treatment and recovery business in 2019. It has proven its technological leadership by developing and operating a mobile, vehicle-mounted refrigerant recovery system and obtaining a New Excellent Technology (NET) certification for waste refrigerant destruction. Moving beyond a simple treatment business, it has grown into a leading green technology enterprise possessing full-lifecycle management capabilities for F-gases spanning recovery, purification, reclamation, and destruction.

Its greenhouse gas reduction performance is also remarkable. Over the past three years (2023–2025), the company recovered and treated 238 tons of refrigerants and 10 tons of $$SF_6$$ , reducing 600,000 tons of greenhouse gases ( $CO2 eq$ ). Its cumulative reduction amount since 2018 reaches 1.38 million tons, including the recovery of 777 tons of refrigerants. This scale is equivalent to the effect of planting approximately 68 million pine trees.

Notable results were also achieved in terms of constructing technological infrastructure. In July 2025, Seonjin Environment cooperated with Korea Electric Power Corporation (KEPCO) to complete the construction of the nation's first hydrogen-utilizing $SF6$ destruction and neutralization plant. As the nation's first practical implementation case capable of safely treating $SF6$ , which has a GWP reaching 23,500, it is expected to serve as a standard model for future application across national power infrastructures. In addition, it established a Carbon Capture and Utilization (CCU) demonstration facility for recycling bittern discharged from purified salt through a government R&D project.

A nationwide recovery network is also in operation. The company runs a stable F-gas recovery system targeting generation sources across the country, including 10 recycling centers, refrigeration/cold storage/HVAC facilities at 34 industrial plants, end-of-life vehicle processing facilities, and KEPCO power installations (including $SF6$ facilities and 15 sites in the Jeju region).

Following the Minister of Environment's Commendation in 2021 (Grand Prize for Star Technology in the Global Top Environmental Technology Development Project) and the Minister of Environment's Commendation in 2018 (Contribution to Environmental Conservation and Refrigerant Management), Seonjin Environment has solidified its status as an industry-representing climate crisis response enterprise by winning this Prime Minister's Commendation.

Kang-woo Lee, CEO of Seonjin Environment, expressed his ambitions, stating, “This award is a meaningful outcome where Seonjin Environment's technological tenacity toward overcoming the climate crisis and achieving carbon neutrality has been recognized at a national level.” He added, “We will continue to further advance our full-lifecycle management capabilities for F-gases to leap forward as a global green technology leader guiding the sustainable future of the Republic of Korea.”

“Transition to Eco-Friendly Refrigerants and Strengthening Carbon Regulations: F-gas Full-Lifecycle Management is the Future Competitiveness”

Seonjin Environment is South Korea’s very first registered refrigerant recovery company and a specialized F-gas enterprise that obtained the nation's first New Excellent Technology (NET) certification for waste refrigerant treatment. The company successfully executed and commercialized a national R&D project under the Ministry of Environment regarding waste refrigerants, securing numerous patent applications and registrations through a combination of government grants and in-house development funding.

Its primary business involves recovering, treating, and reclaiming waste refrigerants generated during the maintenance and decommissioning of various refrigeration and air conditioning systems (such as industrial/commercial chillers and waste home appliances). Specializing in a diverse range of F-gases—including HFCs, HCFCs, CFCs, $SF6$ , and PFCs—the company produces and supplies reclaimed refrigerants from the recovered waste.

Seonjin Environment holds patents related to mobile refrigerant recovery units, vehicle-mounted large-scale refrigerant recovery systems, and pre-treatment units and reclamation equipment for waste refrigerant recycling. Furthermore, the company has accumulated robust system engineering capabilities, which include directly manufacturing gas separation membranes essential for biogas utilization and $CO2$ mineral carbonation, backed by more than 1,000 performance tests.

We sat down with Kang-woo Lee, CEO of Seonjin Environment, to discuss the current state of China’s refrigeration and air conditioning industry and growth strategies for the domestic F-gas sector.

▎ What are the major issues in the Chinese refrigeration and cold storage market?

Traveling back and forth to China frequently, I always observe that China is making strides in every sector at an intimidating speed and on an even more formidable scale. The refrigeration, cold storage, and HVAC sectors are no exception. The core of this global trend driven by China lies in the fact that one can source components for all areas of HVAC&R from a single company, and that they can respond with competitive pricing and technology for everything from small components to massive refrigeration and air-conditioning equipment. This is a point that deepens my reflection on how to cooperate and connect with them to foster our company's growth.

▎ Which products caught your attention the most?

I primarily visited the booths of next-generation F-gas producers and gas cylinder manufacturers. I focused my discussions on specialty gas production companies and also held meetings with some refrigeration, cold storage, and HVAC equipment companies, promising further meetings in the future. I have concluded that we need to actively consider producers of F-gases—including next-generation refrigerants—and specialty gases, as well as manufacturers of equipment and cylinders required for F-gas handling, from a cost-performance perspective.

Ultimately, price competitiveness and technological prowess for various products are the key elements. It is essential to supply products at an affordable price while applying advanced technology. However, since the domestic market has its own unique characteristics and distinct niche fields suited to its market size, Seonjin Environment plans to aggressively target those specific areas.

▎ What is Seonjin Environment's competitiveness?

Seonjin Environment operates in the F-gas pre-treatment, recovery, charging, and purification business, directly manufacturing the necessary equipment and specializing in the sale of reclaimed F-gases. The fact that there were not many exhibits showcasing technology or equipment in this particular field at this exhibition was actually encouraging. It gave me the confidence to push forward more decisively with our actively promoted equipment export business targeting regions like Thailand, Vietnam, Malaysia, and the Middle East.

▎ What is your mid- to long-term vision?

To date, Seonjin Environment has dedicated itself to technology development by investing over 10 billion KRW in self-funded and national R&D project expenditures across the F-gas treatment field, biogas upgrading using separation membranes, and $C O_{2}$ mineral carbonation R&D. Moving forward, we plan to actively pursue business expansion and revenue growth based on these research results and experiences. In addition to our existing F-gas technologies, we will aggressively drive the biogas upgrading and $C O_{2}$ mineralization businesses, while full-scale development gets underway for domestic and international carbon credit projects through F-gas reduction. We also plan to strengthen our nationwide sales capabilities, which includes planning the establishment of a plant in the Seoul metropolitan area, where waste refrigerant emissions are heavily concentrated.

Currently, there are companies cooperating with Seonjin Environment and exploring better relationships. We will forge win-win partnerships to create unparalleled business cases in this field, not only domestically but also internationally. Seonjin Environment will become a company that grows together by maintaining cooperative relationships with any company or organization that seeks a win-win outcome.

Government strengthens full-lifecycle management of refrigerants… pushes to enact tentative 'Refrigerant Management Act'

admin — Thu, 25 Jun 2026 21:14:10 +0000

- Seonjin Environment CEO Kang-woo Lee presents "Latest Policy and Technology Trends Including the Enactment of the Refrigerant Management Act" at the '2026 Refrigeration and Cold Storage Optimization Technology Seminar'

At the '2026 Refrigeration and Cold Storage Optimization Technology Seminar' hosted by the Korea Refrigeration and Air-conditioning Construction Management Association, Kang-woo Lee, CEO of Seonjin Environment, gave a presentation titled "Latest Policy and Technology Trends Including the Enactment of the Refrigerant Management Act." Along with an introduction of his company, he comprehensively explained the importance of greenhouse gas and refrigerant management, the refrigerant regulation roadmap, the current status of the domestic refrigerant management system, and waste refrigerant treatment technologies.

Seonjin Environment is a specialized waste refrigerant company that performs the recovery, reclamation, treatment of waste refrigerants used in refrigerators and air conditioners, as well as the supply of reclaimed refrigerants. The company is promoting businesses to ensure the proper treatment of refrigerants and to establish a resource circulation system.

CEO Kang-woo Lee first introduced the types and sources of the seven major greenhouse gases designated by the UN. Greenhouse gases consist of carbon dioxide ( $CO2$ ), methane ( $CH4$ ), nitrous oxide ( $N2O$ ), hydrofluorocarbons (HFCs), perfluorocarbons (PFCs), sulfur hexafluoride ( $SF6$ ), and nitrogen trifluoride ( $NF3$ ), with $CO2$ accounting for approximately 80% of total emissions. Following $CO2$ , methane and nitrous oxide are the primary greenhouse gases, while the remaining HFCs, PFCs, $SF6$ , and $NF3$ are all fluorinated greenhouse gases (F-gases), characterized by their extremely high Global Warming Potential (GWP). In particular, $SF6$ has a GWP of about 23,500, meaning even small emissions can have a significant impact on global warming.

Refrigerants are also representative greenhouse gases and are regulated worldwide. Refrigerants are substances used to lower heat in refrigeration/cold storage equipment, air conditioners, and industrial chillers, with HFCs, HCFCs, and CFCs being the most prominent examples. If these substances are emitted into the atmosphere, they can cause ozone depletion and global warming, and some refrigerants are known to have a GWP that is about 140 to more than 11,700 times higher than that of $CO2$ .

CEO Kang-woo Lee emphasized that because most refrigerants are colorless and odorless, they have often been perceived as having relatively low human toxicity, leading to lax management in the past. However, he stressed that systematic management is now essential as greenhouse gas reduction policies become more stringent.

Refrigerant regulations are being progressively strengthened through international agreements. The reduction of ozone-depleting substances, such as CFCs and HCFCs, has been carried out in accordance with the Montreal Protocol, and the production and distribution of CFCs have been completely banned in South Korea since 2010. Currently, HCFC-based refrigerants are in their reduction phase, and the production and import quotas for R22, a major representative refrigerant, are continuously being scaled back. Since South Korea relies on imports for about 98% of its refrigerants, price increases due to a shrinking supply are inevitable.

CEO Kang-woo Lee highlighted that HCFCs are scheduled to be reduced by approximately 97.5% by 2030, presenting the use of reclaimed refrigerants as a critical alternative for existing facilities. He emphasized that because replacing refrigerants in existing R22 equipment is often difficult, it is necessary to utilize recovery and reclamation practices until the end of the equipment's lifespan.

The reduction of HFC refrigerants is also being pushed forward under the Kigali Amendment to the Montreal Protocol. Ultimately, a transition toward natural refrigerants such as $C O_{2}$ and ammonia, alongside low-GWP HFO-based refrigerants, is projected to take place.

However, natural refrigerants and next-generation refrigerants are often 5 to 10 times more expensive than conventional ones, and challenges remain regarding the need for performance improvements.

The domestic consumption of fluorinated greenhouse gases is estimated to be around 32,800 tons, which translates to approximately 55 million tons of $C O_{2}$ equivalent ( $C O_{2} eq$ ). He explained that while this accounts for about 7% to 8% of the national greenhouse gas emissions, the actual physical volume of the substance is less than 1%, which is due to its high GWP characteristics.

Mr. Lee also underscored that since refrigerants remain sealed inside equipment, proper recovery alone can yield a significant greenhouse gas reduction effect.

Currently, domestic regulations regarding refrigerants are dispersed across five different statutes: the ▲Act on the Control of Manufacture, etc. of Specific Substances for the Protection of the Ozone Layer, ▲Framework Act on Resources Circulation, ▲Clean Air Conservation Act, ▲Wastes Control Act, and ▲High-Pressure Gas Safety Control Act. Consequently, related business operators must comply with all of these regulations simultaneously.

CEO Kang-woo Lee explained that to resolve this fragmented regulatory issue, he understands the government is currently pushing for the enactment of the tentative "Refrigerant Management Act."

The core of the Refrigerant Management Act is to establish a single, unified legal framework that integrates all refrigerant-related regulations. It is expected to include the introduction of a mandatory refrigerant usage reporting system, the expansion of the scope of regulated refrigerant-using equipment, the tightening of refrigerant leak management, the broader utilization of reclaimed refrigerants, and relevant penal regulations. The government is reportedly planning to submit the bill to the National Assembly during the first half of this year to pursue its enactment.

According to the HFC substance transition schedule announced in December 2025, the transition of refrigerants by product category will be implemented in phases. For heat pumps and air conditioning equipment, the use of refrigerants with a GWP of 750 or higher will be restricted starting from 2028, and the same standard will apply to small-scale refrigeration and cold storage facilities from 2028 as well. For large-scale refrigeration facilities, the use of refrigerants with a GWP of 750 or higher will be restricted starting from 2030, and the application of low-GWP refrigerants is projected to expand to commercial display showcases and other refrigeration equipment.

CEO Kang-woo Lee emphasized that amid these policy shifts, refrigerant recovery has become more critical than ever. Refrigerant recovery is becoming an essential procedure during the maintenance of refrigeration systems, and he stated that the registration requirements for refrigerant recovery businesses are expected to become much stricter once the Refrigerant Management Act is enacted in the future. Accordingly, he explained that establishing a proper refrigerant recovery system will be a vital factor for maintenance companies to secure their market competitiveness moving forward.

Mr. Lee stated that refrigerant recovery is becoming a mandatory procedure in the refrigeration maintenance process, and registration requirements for the refrigerant recovery business are expected to tighten following the future enactment of the Refrigerant Management Act. Consequently, he explained that for maintenance companies, equipping themselves with a refrigerant recovery system is crucial to securing competitiveness.

CEO Kang-woo Lee also introduced the disposal standards and technologies for waste refrigerants. When recycled, waste refrigerants must meet the KS I 3004 quality standards or the quality standards of new refrigerants. When disposed of, they must be decomposed by 99.9% or more through incineration or oxidation-reduction reactions.

The decomposition of waste refrigerants is a technically challenging process.

Refrigerants possess flame-retardant or non-flammable characteristics, and fluorine or chlorine-based halogen elements are generated during the decomposition process, which suppresses combustion reactions. Furthermore, incomplete decomposition can generate $$CF_4$$ , which has an extremely high GWP. The concentration of HF or HCl generated during the decomposition process reaches levels of 100,000 to 200,000 ppm, significantly exceeding the emission allowance standard (2 ppm), thereby requiring advanced process control technology.

At the end of his presentation, CEO Kang-woo Lee introduced Seonjin Environment's waste refrigerant treatment systems, including its waste refrigerant reclamation and destruction technologies, and emphasized the necessity of establishing a full-lifecycle management system for refrigerants.

admin — Thu, 25 Jun 2026 20:50:10 +0000

(Kuala Lumpur = World Korean News) Overseas Reporter Seo Kyu-won

Sunjin Environment, a South Korean company possessing technology for reprocessing waste refrigerants from air conditioners, signed a memorandum of understanding (MOU) with GENSIS, a Malaysian company, on November 23 to transfer relevant technologies.

Sunjin Environment is a company commissioned by the Korea Energy Agency to transfer technology. Since last March, the Korea Energy Agency (President Lee Sang-hoon) has been conducting a "Fine Dust and Greenhouse Gas Reduction Support" project with the Standards and Industrial Research Institute of Malaysia (SIRIM). The transfer of "waste refrigerant recovery and reclaimed refrigerant" technology is also part of this project.

Under the 1987 Montreal Protocol signed in Canada, 196 countries worldwide must progressively reduce the volume of refrigerants they consume to prevent environmental destruction caused by refrigerants. Furthermore, as Malaysia has declared a 30% reduction in hydrofluorocarbon (HFC) consumption by 2035, the Malaysian government is actively seeking to import waste refrigerant treatment technologies from overseas.

Sunjin Environment possesses technology that can perfectly recover and reclaim HCFC and HFC refrigerants, which are widely used in Malaysia. Lee Mu-jin, team leader at Sunjin Environment, stated at the MOU signing ceremony that day, "By reclaiming refrigerants, which are primary culprits of environmental destruction, we expect to contribute to carbon neutrality and a circular economy, while also benefiting relevant business initiatives in both nations."

[Cheonji Ilbo Busan = Reporter Yoon Seon-young] As Busan Metropolitan City was selected for the "Root Industry Specialized Complex Support Project" contest hosted by the Ministry of Trade, Industry and Energy, it will push forward with a project to provide mobile waste refrigerant recovery and reclaimed refrigerant charging services by the end of this year.

Root technology refers to basic process technologies, such as surface treatment technology used across the entire manufacturing industry, and next-generation process technologies essential for the future growth and development of manufacturing, including injection molding/pressing, precision processing robots, and sensors. Currently, there are five specialized complexes in Busan, including the Busan Noksan Surface Treatment Industry Cooperative.

This project aims to rapidly recover waste refrigerants generated from member companies belonging to the Busan Noksan Surface Treatment Industry Cooperative and to recharge them with reclaimed refrigerants purified using the recovered waste refrigerants. The total project cost is 130 million KRW, consisting of 91 million KRW in national funds, 19 million KRW in city funds, and 20 million KRW in self-burden from the cooperative and its member companies.

Refrigerants mainly used in the surface treatment industry cause high climate change even in small amounts. The city expected that by directly recovering and recycling waste refrigerants for proper treatment, it would reduce greenhouse gas emissions caused by refrigerant use and improve the competitiveness of the surface treatment industry, which is a root industry.

Sunjin Environment Co., Ltd., a company based in Busan (Saenggok-dong), will independently develop and deploy mobile vehicle-mounted equipment to minimize downtime for facility operations at workplaces and monitor greenhouse gas reduction results after the completion of the project.

Lee Keun-hee, director of the Environment and Water Policy Bureau of Busan City, said, "Although various projects for carbon neutrality have been pushed forward recently, the reality is that technologies to reduce non-carbon dioxide (Non-CO2) rather than carbon dioxide are lacking," adding, "We expect various greenhouse gas reduction technologies to be activated with the selection of this public contest project."

Sunjin Environment Commercializes Vehicle-Mounted Waste Refrigerant Recovery Unit

admin — Thu, 25 Jun 2026 20:40:37 +0000

Capable of Recharging Reclaimed Refrigerant… Scaling Up Processing Capacity and Speed

As interest in greenhouse gas emissions reduction and global warming grows, regulations on refrigerant emissions are also tightening. In South Korea, with the management of refrigerant-using equipment becoming mandatory, there is an increase in workplaces that maintain refrigerant management logs and recover refrigerants during decommissioning or demolition. Consequently, the number of registered refrigerant recovery businesses is on a steady rise.

Since businesses must use refrigerant recovery equipment registered with the Korea Environment Corporation (such as refrigerant recovery units, recovery/charging cylinders, and leak detectors) when registering for a refrigerant recovery business, inquiries regarding the purchase of refrigerant recovery units are also increasing.

However, in the case of small-scale refrigerant recovery units, the gaseous refrigerant recovery speed is slower than that of mobile or vehicle-mounted recovery systems, causing major inconvenience. For large-scale workplaces that hold refrigerants in metric-ton volumes, operations using small recovery units are practically impossible.

Accordingly, Sunjin Environment (CEO Lee Kang-woo) has completed the development and commercialization of a Vehicle-Mounted Waste Refrigerant Recovery and Reclaimed Refrigerant Charger. This system safely recovers waste refrigerants while reducing their emission from refrigeration facilities, and supplies reclaimed refrigerants to save energy and reduce greenhouse gases. The company is now actively utilizing it for waste refrigerant recovery at various industrial sites.

▲ Korea's First Vehicle-Mounted Waste Refrigerant Recovery and Reclaimed Refrigerant Charger Developed by Sunjin Environment.

Implementing 'Door-to-Door' Technical Services

The mobile refrigerant recovery system (RC030/050/070, RS20) recently developed by Sunjin Environment is a recovery unit capable of operating while loaded onto a 1-ton truck or van. It functions as a complete package (refrigerant recovery/recharging system and recovery/charging cylinders) integrated with the vehicle. By mounting the waste refrigerant recovery and reclaimed refrigerant charging equipment directly onto the vehicle, the company has realized South Korea's first "Door-to-Door" technical service—visiting clients on-site to recover waste refrigerants and simultaneously inject reclaimed refrigerants for immediate reuse.

Furthermore, to optimize the efficiency of waste refrigerant recovery and recharging operations and resolve site accessibility constraints, the service allows remote recovery and recharging from chillers located 0 to 200 meters away without unloading the recovery unit from the vehicle. This fundamentally addresses the challenges of scaling up processing capacity, accelerating processing speed, and overcoming physical accessibility boundaries faced by existing waste refrigerant recovery clients.

Providing a vehicle-mounted waste refrigerant recovery and reclaimed refrigerant charging service enables simultaneous, continuous, and rapid recovery and recharging operations. Additionally, the system features built-in self-maintenance technology to minimize required onsite manpower.

Notably, monitoring both the waste refrigerant recovery and reclaimed refrigerant charging processes allows for rational, volume-based cost processing. Through real-time monitoring of refrigeration systems, the service can also predict refrigerant contamination levels and provide comprehensive status reports on both the refrigeration equipment and the refrigerant itself.

An official from Sunjin Environment stated, "Through real-time monitoring of refrigeration facilities, clients can verify operational efficiency and track optimal waste refrigerant replacement cycles, enabling highly efficient refrigerant management at industrial sites." They added, "This system is perfectly suited for all types of workplaces, including large-scale industrial complexes."

Development of Vehicle-Mounted Waste Refrigerant Recovery Unit

▲ Vehicle-Mounted Waste Refrigerant Recovery Unit Developed by Sunjin Environment.

Sunjin Environment, which possesses technology that can handle the recovery, reclamation, and treatment of refrigerants used in chillers and air conditioners all at once, drew significant attention at 'HARFKO 2022' by showcasing its vehicle-mounted waste refrigerant recovery and reclaimed refrigerant charging service.

Following the amendment and implementation of the Clean Air Conservation Act, owners of refrigerant-using equipment are mandated to recover waste refrigerants themselves by possessing the equipment, facilities, and manpower specified by the Act, or to recover them through registered refrigerant recovery companies and commission the treatment to waste gas treatment or waste management companies.

Under the Clean Air Conservation Act, managed equipment refers to devices with a daily refrigeration capacity of 20 tons or more, and recovered waste refrigerants must be handed over to waste management companies for treatment.

During chiller maintenance periods, equipment capable of recovering or injecting large volumes of refrigerant is essential, and the recovery speed of waste refrigerant has become a critical factor in shortening total work time.

Accordingly, Sunjin Environment developed a vehicle-mounted waste refrigerant recovery unit. By equipping a vehicle with waste refrigerant recovery and reclaimed refrigerant charging systems, the company can provide Korea's first 'Door to Door' service that visits sites to recover waste refrigerants and simultaneously inject reclaimed refrigerants for reuse.

Furthermore, to improve the efficiency of waste refrigerant recovery and recharging operations and to resolve accessibility issues, the company provides a service capable of remotely recovering and recharging waste refrigerants from chillers located 0 to 200 meters away without unloading the recovery unit from the vehicle. This completely addresses the challenges of large-scale capacity, processing speed, and accessibility faced by existing waste refrigerant recovery demanding companies.

Particularly, it can recover 3 tons of waste refrigerant per hour, which is twice as fast as the 1.5 tons per hour recovery rate held by Robinair, a world-class US company. The remote recovery distance has also been extended to 200 meters, double the global standard of 100 meters. Additionally, the purification purity of its waste refrigerant purification and reclamation facility stands at 99%, overwhelming the global level of 98% and the domestic standard of 95%.

Sunjin Environment Co., Ltd. (Co-CEOs Lee Kang-woo, Seok Min-gwang) will participate in 'ENVEX 2022 (International Exhibition on Environmental Technology & Green Energy)' held at COEX Hall A in Seoul from June 8th (Wed) to 10th (Fri). Sunjin Environment is a company that provides a one-stop solution to handle the recovery, treatment, and recycling of waste refrigerants all at once. The company treats fluorinated waste refrigerants, which are greenhouse gases that seriously impact climate change, global warming, and ozone layer depletion. It operates a business that contributes to the government's implementation of the Paris Agreement through greenhouse gas reduction. It has completed a process facility capable of solving the recovery, treatment, and recycling of waste refrigerants generated during the maintenance and disposal of various refrigeration and air conditioning equipment—such as industrial chillers and waste home appliances—in a one-stop manner within a single plant. Believing that global demand will increase due to the international community's awareness and strengthening of regulations on atmospheric environmental protection, Sunjin Environment is striving this year to focus its corporate capabilities on foreign markets, targeting differentiated waste refrigerant treatment businesses, exporting waste refrigerant treatment plant facilities, and business models. The amended Clean Air Conservation Act in South Korea has been in effect since November 2018, and the regulations under this law are expected to tighten in the future. Accordingly, Sunjin Environment plans to explain the importance of reducing climate change substances, recovering waste refrigerants, and recycling them through compliance with waste refrigerant management regulations at this exhibition. In addition, it will provide solutions to resolve these issues utilizing its independently developed waste refrigerant recovery and treatment services.

The 'Vehicle-Mounted Waste Refrigerant Recovery and Reclaimed Refrigerant Charger' developed by Sunjin Environment implements Korea's first "Door-to-Door" technical service. By equipping a vehicle with waste refrigerant recovery and reclaimed refrigerant charging systems, the company visits sites to recover waste refrigerants on the spot while simultaneously injecting reclaimed refrigerants to reuse them. In addition, to improve the efficiency of waste refrigerant recovery and recharging operations and to solve accessibility issues, the company provides a service capable of remotely recovering and recharging waste refrigerants from chillers located 0 to 200 meters away without any equipment defects. Through this, it can resolve the issues of processing capacity and larger-scale processing speeds faced by existing companies demanding waste refrigerant recovery. Sunjin Environment has also developed an 'Automatic Heat Exchanger Cleaning System.' By solving the fouling problem in the heat transfer tubes of shell-and-tube heat exchangers—such as those in chiller condensers and absorbers—it reduces equipment operation costs through heat exchanger energy savings. During equipment operation, a specially made sponge ball, slightly larger than the inner diameter of the tube, is passed through the heat exchanger tubes (condensers, absorbers, etc.) 8 to 10 times a day to clean off fouling materials such as scale and slime formed inside. This keeps the inside of the tubes clean, thereby improving heat transfer performance, reducing energy consumed for equipment operation, and extending the lifespan of the tubes.

An official from Sunjin Environment explained, "Existing waste refrigerant management required long working hours depending on the size of the workplace and refrigeration equipment. Different environments at each site caused various difficulties and risk factors, leading to a decrease in the refrigerant recovery rate. Furthermore, using contaminated refrigerant gas in refrigeration equipment for a long time causes reduced equipment efficiency, shortened lifespan, increased energy consumption, and safety accidents." They added that the 'Vehicle-Mounted Waste Refrigerant Recovery and Reclaimed Refrigerant Charger' was developed to address these issues. They continued, "When heat transfer tubes in a heat exchanger become fouled, heat transfer performance drops, leading to increased energy consumption. Moreover, concentration cells partially form on the heat transfer tubes, inevitably causing electrochemical corrosion. To solve this, conventional methods mostly relied on mechanical or chemical cleaning, which inevitably required shutting down equipment operations. Furthermore, fouling starts forming again the moment operation resumes after cleaning, creating concerns over environmental pollution as time passes. To resolve this, we developed the 'Automatic Heat Exchanger Cleaning System.'" Currently, Sunjin Environment boasts a reclamation rate and quality close to 100% compared to new refrigerants after removing impurities contained in waste refrigerants. Meanwhile, the company produces and supplies reclaimed refrigerants to major Korean conglomerates, state organs, and public enterprises at a price level of 70% to 80% compared to new refrigerants. In addition, in June 2019, the company signed a 10 billion KRW agreement to supply a refrigerant treatment plant to Saudi Arabia.

A total of 6 billion won was invested in this exclusive plant, including R&D expenses, and through continuous R&D with excellent researchers at the master's and doctoral level in the organization, more than 20 related patents such as thermal destruction and detoxification systems for waste refrigerants were also applied for and registered. In particular, the 'waste refrigerant decomposition technology using swirling injection of combustion air' is taking a unique and differentiated path as a self-accredited environmental research and development company, such as acquiring the new technology (NET) certification from the Ministry of Trade, Industry and Energy for the first time in Korea. Co-CEO Seok Min-kwang said, “There are not many companies in developed countries such as the United States and Japan that possess waste refrigerant recovery/refining and thermal treatment technologies at the same time, and it is the first in Korea to have an advanced environment. The 'waste refrigerant detoxification and treatment technology' developed as a task was selected as the most excellent technology among the global top environmental technology development projects of the Ministry of Environment for the past 10 years, and received the Best Star Technology Award (Minister of Environment Award).” 'Waste refrigerant detoxification and treatment technology' developed by Advanced Environment produces and sells recycled refrigerant after removing impurities contained in waste refrigerant in consideration of resource circulation. can be destroyed. In particular, it is evaluated as a combustion technology dedicated to the waste refrigerant that can reduce the energy consumption required to decompose the thermally stable waste refrigerant in the destructive treatment of waste refrigerant containing halogen elements such as fluorine (F) at high temperature. When the combustion air is supplied in the tangential direction to the double-structure swirl flow type combustor, it rotates along the inner wall of the combustor and then joins the rotating flame. The preheated air discharged into the combustion chamber rotates along the inner wall of the combustion chamber and joins the flame formed in the center of the combustion chamber to be used as an oxidizer for combustion. The core technology is to improve energy efficiency by cooling the combustion chamber with combustion air and using the air preheated in the combustion chamber cooling process as a waste refrigerant oxidizer instead of constructing refractory materials to protect the outer wall of the combustor. The combustion chamber flame achieved a thermally stable decomposition rate of over 99.99% of the waste refrigerant by mixing the waste refrigerant, auxiliary fuel, and oxidizing agent by Turbulence at a maximum temperature of 1,400℃ and securing sufficient residence time.

Self-developed refrigerant recovery and purification system (RP-1000)

Advanced environment develops refrigerant thermal decomposition technology through thermal reaction with methane, one of the waste refrigerant treatment technologies designated by the UN, fractionation liquefaction technology using liquefaction point, and Korea's best gas separation membrane technology and adsorption technology. commercialized. Co-CEO Seok Min-kwang said, “Based on this process technology, after removing impurities in the waste refrigerant, we eco-friendly production and supply of recycled refrigerant that has a regeneration rate and quality close to 100% compared to that of a new refrigerant. Demand is increasing every year,” he said. Fractional liquefaction is a technology that separates mixed refrigerants in stages using different liquefaction points (boiling points), and is most widely used for refrigerant regeneration. It is characterized by low energy consumption as it is the reverse process of fractional distillation widely used in crude oil refining. The membrane separation method is a technology that separates the membrane material by the difference in the permeation rate due to the physicochemical interaction between the membrane material and the permeating gas molecules. Co-CEO Seok Min-kwang said, “When a hollow fiber type separator is applied, the processing capacity per unit volume is high, but compared to the fractional liquefaction technology, it is a research stage and additional research is needed for materials and capacity expansion to commercialize it.”

Car-mounted waste refrigerant recovery and regenerated refrigerant charging service

In addition, Advanced Environment developed a vehicle-mounted refrigerant recovery system for the first time in Korea, providing waste refrigerant recovery and regenerated refrigerant charging services. is under development. The facility utilization rate is less than 30% due to lack of legal/institutional and management measures. By using the advanced environment's 'waste refrigerant detoxification and treatment technology', it is possible to reduce 500 kg of waste refrigerant per hour into reusable regenerated refrigerant and thermal treatment of 50 kg of non-renewable refrigerant to reduce greenhouse gas emissions by hundreds of thousands of tons per year. However, in accordance with the Air Environment Conservation Act and the Waste Management Act, the entire amount of waste refrigerant must be recovered and processed by specialized companies, but the reality is that the amount processed is as low as 1%. Currently, the utilization rate of facilities in advanced environments is less than 30% of its processing capacity due to lack of legal and institutional arrangements and lack of management measures. Co-CEO Seok Min-kwang mentioned that in order to improve this, the subject of legal regulation (or management) should be expanded to not only high-pressure refrigerants but also low-pressure refrigerants, and the refrigeration capacity should be included in the regulation from refrigerators over 20RT to small refrigerators. It also suggested the need to prepare a management plan (sanction measures) for refrigerant leakage, strengthen punishment, and establish a management system for the entire process of purchasing, injecting, discharging and recovering new refrigerant, refining, recycling and refining. In addition, about two refrigerant-related methodologies have recently been registered for the emission trading system related to spent refrigerant, and advanced environment is also in the process of registering methodologies with the Ministry of Environment. pointed out that

Refining equipment by refrigerant type

Doing our best to become a company that takes charge of the nation's future new growth engine Advanced Environment will also strengthen its competitiveness in the domestic and overseas markets in preparation for an increase in global demand due to the strengthening of the international community's awareness and system for air environment protection in the future. Co-CEO Seok Min-kwang said, “First of all, in 2022, we will focus our company-wide capabilities on overseas exports such as our differentiated waste refrigerant treatment business, direct export of waste refrigerant treatment plant equipment, and export of business models for overseas markets, We plan to dramatically increase the amount of waste refrigerant recovery and processing through the expansion of our second business site.” Above all, advanced environment is superior in terms of ease of handling and management of waste refrigerants by establishing a system that can design and manufacture all facilities on its own, such as technology that can recycle and dispose (thermal decomposition), and process waste refrigerants in one stop. is occupying In addition, it has sufficient price competitiveness, such as having its own technology, no burden on technology fees, and low processing costs due to one-stop processing in a single plant.
