บทคัดย่อ

Renewable energy technology is being adopted into energy plans worldwide to reduce the mounting CO2 emissions of traditional energy sources. Currently in Thailand, there are approximately 15 million solar panels (2600 MW) which will need to be disposed of in the coming years. The average lifespan of a crystalline silicon panel is between 20 and 30 years, and responsible treatment of these end-of-life panels is necessary to minimize environmental burdens. Thailand's current plan is to landfill these panels. This study hopes to shed light on the environmental and economic paybacks that could materialize from recycling solar panels. It has been hypothesized that recycling solar panels could result in less environmental burdens than landfilling, but at an added monetary cost. Using LCA methodology and the EcoInvent database, this paper compares the environmental impacts of landfilling end-of-life crystalline silicon panels with those of two different recycling methods. By recycling silicon-based solar panels, valuable metals within the panels can be recovered instead of lost to the landfill. Recycling PV panels is less environmentally burdensome than landfilling when credits are applied to the recycling methods for the avoided production of materials that are recovered from the panels. Using the discounted cash flow method, this paper also compares the three waste management plans financially, as costs will inevitably influence how PV waste is managed in Thailand in the years to come. Neither of the recycling facilities were found to be economically profitable, however the cost to recycle could be as little as $0.03 per kg. ฉ 2019 Elsevier B.V.
