Inspecting and Analyzing the Collection and Recycling systems of Waste Batteries and Waste Lamps, and Evaluating their Effectiveness

Absrtact
The project period was from Jan 16, 2018 to Dec 31, 2018. The information of high energy batteries for wearable devices, electric or hybrid vehicles batteries (secondary Li-battery), LED lamps and OLED lamps had been investigated and analyzed for the evaluation of collection and recycling or regulating as recyclable wastes. 15 different batteries had been sampled and analyzed. The major contents of the LiFePO4 battery were iron and manganese. The major compositions of the secondary Li batteries which used by cell phones, mobile computers and power banks were nickel and cobalt. The sampling and testing works of 70 lamps were finished. The unit weight of mercury content calculated by average testing results from 2015 to 2017 for the compact fluorescence lamp was lower than the regulation coefficient. The unit costs for collection and recycling of batteries were reviewed and the draft of levy and subsidy rate was proposed. Also suggested the different brackets (decided by collection rate) rates for batteries and the limitation of recycled products for the subsidy rate. The investigation of waste batteries distribution already received the collectors/recyclers’ replies (valid survey) whose collection volumes proportion was over 80%. Based on the result, the project proposed suggestions of the collection rate calculation method revising and the collection path reporting. By recycling waste batteries with the arc furnace, the waste treatment plant Katec Creative Resources Corp. will apply the qualification of regulated recyclable wastes recycler and add waste batteries as one of its treating items around the end of this year. Another waste treatment plant Taiwan Steel Union Co., Ltd. will apply the second environment impact assessment report covered adding waste batteries as one of its treating item in December. The collection channels of waste Li batteries from motorcycle maintenance workshops were waste metals collectors and municipal cleaning crews. Most of waste Li batteries from car maintenance workshops were collected by domestic recyclers. According to the investigation result in 2017, the project proposed the breakage prevention strategy for consumers in collection stage, municipal cleaning crews and collectors in transporting stage, collectors and recyclers in storage stage. Also held 6 educational sessions of lamps breakage prevention for municipal cleaning crews. Based on the goal of pollution reduction and environment risk, the lamps’ breakage tolerance rate standard 7% should be kept. The waste batteries collection campaign will be assisted and held by the 2 chain convenient stores (7-11 and family mart). The attracting point for consumers was that the waste battery collection can deduct the price for shopping. Total 160 unregistered entities had been inspected through the web and retailers during the four quarters. EPA will continue to aduit the recycling fees they should submit. By reviewing and tracing the 2012 to 2017 achievements for subsidizing the inventing and researching of regulated recyclable wastes collection and recycling in waste batteries and waste lamps fields, evaluated the feasible of extended promoting for specific programs by the aspects of marketing supply, practical application , and economic efficiency.
