Understanding manufacturers’ and consumers’ perspectives towards end-of-life solar photovoltaic waste management and recycling

摘要

Abstract The present study highlighted the issue of end-of-life photovoltaic waste before government, policy makers, waste regulators and fills the gaps between various stakeholders by exploring their perceptions towards end-of-life solar waste management. Respondents’ waste handling practices, willingness to pay towards recycling, and their mindset towards problematic situation of upcoming photovoltaic waste were investigated via a survey-based study. Findings indicated that consumers are less concerned about photovoltaic waste as 60% of them?are planning to sell their used panels to rag-pickers, however, willing to pay a part of recycling/handling cost, if required. Majority of respondents (>?80%) never considered fate of end-of-life photovoltaics, though?willing to pay 15% of handling costs. In terms of responsibility for recycling, 60% consumers think that?it is government’s responsibility, whereas 51% manufacturers think that it is a common responsibility of government, consumer, seller/manufacturer. In respect to ranking of drivers, barriers and enablers towards solar waste management, consumers scored factors more moderately than manufacturers, highlighting the less apprehension and thoughtfulness concerning the issue. The most critical barrier identified was high recycling cost, and can possibly be overcome by implementation of research & development on feasible and economically sound recycling processes. Statistical analysis shows that the respondent category and their respective regions significantly affect the ranking of factors and point-of-view towards various aspects. The findings clearly indicate that self-take-back collection and recycling facilities, material recovery and recycling incentives are the main factors affecting end-of-life panels handling. As an input to policy makers, it is necessary to understand?the findings presented in present study on consumers and manufacturers’ mindsets regarding photovoltaic waste issue and their willingness to participate in recycling activities.Graphical abstract
