The purposes of this project include: (1) The refrigerant of waste home appliance investigating: This project researched the refrigerant standards of USA, Canada and Australia and compared the difference. This project also calculated the collection ratio to sample 12 times of refrigerant from waste air-conditioner and 7 times of refrigerant from waste refrigerator, the result were 60.5% and 22.2% separately. This project researched the residual of ozone in the PU foam and the refrigerant concentration near the exhaust pipe of waste refrigerator shredding machine and the results which were compared with Germany’s standard needed to enhance more. We assisted the 2 enterprises with editing safety process document for dangerous zone and risk assessment. Finally, according above, this project proposed the flame-proof and safety process procedure standard for eco-refrigerant and refrigerant collection suggestions. (2)The channels of waste and recovery materials: this project this project would make indices included annual production, annual treatment, price and hazardous waste to assess, and metal materials (copper and aluminum) and printed circuit board (PCB) were selected to assess at recycling program. For enhancing the copper purity and metals recycling from PCB, this project suggested to install equipment. Moreover, this project investigated the international recycling channel of panel glasses and the channels were to make glass asphalt, civil structure, bricks or cement, among above, the best one was to make glass asphalt, and CRT glass was utilized to make to synthesis aggregates, ceramic tiles or radiation-protective glass. This project was to try to make permeable brick and exam the toxic reaction first this year. (3)To counsel related retailers in the take-back system: The regulated system retailers for take-back were 4,667 and collection and recyclers were 250. For improving the take-back system information, this project held 10 information meetings and 30 on-site counselings, and served by toll-free call, e-mail and discussion forum. Further, this project revised the regulation and finished 23 different forms for take-back system. (4) To inspect the reporting and management system for take-back system: from January 1 2012 to December 31 2012, the waste home appliances which were collected through take-back system were 73,414 and parts of 35,852 were sent to recyclers. To examine the efficacy of home appliance take-back system, the growth of collection numbers increased 23,949 items (the increasing ratio was 96%) compared with the same period (July to December) last year, and it showed that the modified take-back system rise the retailers coordination. The take-back system was carried out to increase 245,402 items (the increasing ratio was 25%). This project assisted to make S.O.P for inspecting process and forms and collect suggestions from experts to simplify the manifests and enhance the tracks system for waste.
