Since the establishment of the company, we have conducted research on global technological trends regarding PCB (polychlorinated biphenyl) treatment and provided information to stakeholders both domestically and internationally. We have also developed various proprietary treatment technologies in-house. Based on our high-level treatment technology, knowledge of related legislation, and a network with companies possessing cutting-edge technologies from Europe and the United States, we can quickly find solutions to unprecedented challenges in Japan. At Rijen, after research and development to meet the strict domestic standards, we underwent verification tests and received an evaluation in October 2015 from the PCB Treatment Technology Research Committee, stating that our treatment system "enables the decomposition and removal of PCBs in insulating oil and the cleaning treatment of PCBs that have seeped into or adhered to transformer containers and materials." We respond to our customers' needs with our extensive knowledge and experience. As a pioneer in PCB treatment, we provide rational and optimal solutions to our customers' challenges and requests. From investigation and analysis to the selection of treatment methods, planning treatment strategies, and dealing with local governments, you can leave all the cumbersome tasks to us. Please feel free to contact us first.

Fluorescent lamp ballasts that have been in use for over 40 years may contain highly toxic PCBs (polychlorinated biphenyls). The PCB Special Measures Law, revised in 2016, mandates the disposal of PCBs within a specified timeframe. Violations of this obligation can result in improvement orders, penalties, and enforcement actions. The disposal cost for ballasts containing high concentrations of PCBs is quite expensive, approximately 100,000 yen per unit. Rijen will have specialized workers conduct a thorough investigation and assessment of the PCB content in the ballasts that customers are using and storing, utilizing their extensive sorting knowledge and skills. We will disassemble ballasts that contain PCBs as much as possible and properly separate waste by concentration, significantly reducing disposal costs for our customers. We also handle all the complicated tasks involved in registering with JESCO, a facility for high-concentration PCB treatment, including leakage prevention measures at the work site, coordination with disposal and collection transport companies, and administrative reporting to local governments, all in a one-stop service. You can trust us to take care of it with peace of mind. Specific costs and schedules will vary depending on the customer's usage and storage conditions, as well as the number of ballasts. The investigation and preliminary estimate proposal are provided free of charge, so please feel free to contact us first.

Is the waste oil generated during the replacement of transformer insulating oil still stored because it is contaminated with PCBs and cannot be disposed of? The PCB Special Measures Law, revised in 2016, mandates the disposal of PCBs within a specified timeframe. Strict measures such as improvement orders, penalties, and forced execution are expected to be imposed for violations of this obligation. The treatment of insulating oil contaminated with PCBs varies depending on the contamination concentration, but the acceptance criteria for "high-concentration PCB waste" exceeding 5000 ppm are very strict, resulting in significantly higher disposal costs. With our advanced expertise and knowledge, we can separate and remove impurities from the contaminated oil, and also reduce the contamination concentration in the storage containers through advanced oil removal technology, enabling more cost-effective treatment. We handle all the complicated tasks such as the complex registration procedures for JESCO, a high-concentration PCB treatment facility, leakage countermeasures at the work site, coordination with treatment and collection transportation companies, and administrative reporting to local governments, all as a one-stop service. You can trust us to take care of it with peace of mind. Specific costs and schedules will vary depending on your storage situation and the amount of waste oil. The investigation and proposal for a rough estimate are provided free of charge, so please feel free to contact us first.

We will clean and neutralize transformers with PCB concentrations in insulating oil ranging from over 0.5 ppm to 5000 ppm (0.5%). We will transport a mobile treatment unit to the storage location, connect it to the transformer, and perform the cleaning operation in a closed system, eliminating concerns about PCB leakage, dispersion, or worker exposure. After neutralization, cutting and dismantling can be done at a low cost. Additionally, the materials of the transformer after cleaning can be recycled as valuable metals, preventing the loss of precious resources. At Rejenn, after research and development to meet strict domestic standards and through demonstration tests, we received an evaluation in October 2015 from the PCB Treatment Technology Research Committee stating, "This is a treatment system that enables the decomposition and removal of PCBs in insulating oil and the cleaning of PCBs that have seeped into or adhered to the container and materials of the transformer." We respond to customer requests with extensive knowledge and experience. You can trust us with confidence. Specific costs and schedules will vary depending on the condition and number of transformers. The investigation and proposal for an estimated cost are provided free of charge. We also have one of the industry's smallest units capable of handling transformers installed in difficult-to-access or narrow locations. Please feel free to contact us first.

The PCB Special Measures Law, revised in 2016, mandates the disposal of PCBs within a specified timeframe. Even for PCB-contaminated transformers currently in use, it is necessary to cease their use and dispose of them within the disposal period. Strict measures, including improvement orders, penalties, and forced execution, are expected to be imposed for violations of this obligation. Rijen has developed the HED system, which connects transformers to processing equipment, enabling highly efficient oil extraction and replacement of PCB-contaminated insulating oil with non-PCB oil. This ensures reliable oil extraction and replacement. Since the work is conducted in a closed system, there is no risk of workers being exposed to PCBs or of PCBs being dispersed or leaked. The size of the processing equipment is among the smallest in the industry. It can be used for transformers located in basements of buildings with restricted access or in areas where vehicles and heavy machinery cannot easily enter. Specific costs and schedules will vary depending on the customer's usage conditions, the number and dimensions of transformers, and the amount of oil involved. The investigation and preliminary estimate proposal are provided free of charge, so please feel free to contact us first.
