Sustainable photovoltaic recycling to mitigate environmental
We consider realistic constraints such as recycling opportunities, resource and mineral supplies, waste treatment capabilities, and climate goals for PV development.
The service life arrival of photovoltaic panels will generate a large amount of solid waste. It is estimated that the amount will reach 1,957,099 tons by 2038. The recycling of photovoltaic panels is the key to realizing waste treatment and utilization of resources.
In most countries, PV panels are classified as general or industrial waste and managed in accordance with general waste treatment and disposal requirements . Beyond general waste regulation, voluntary and regulatory approaches have been specifically developed for managing end-of-life PV waste.
Even though solar PV panels significantly differ from typical consumer electronic products, global regulators view PV panels increasingly in the context of e-waste regulations. Solar PV currently accounts for less than 1% of total annual e-waste volumes.
To address environmental challenges associated with the increasing volume of EOL PV panels, the European Union (EU) included PV waste in the updated Waste Electrical and Electronic Equipment (WEEE) Directive (2012/19/EU) (Mahmoudi et al., 2019, Li et al., 2024).
We consider realistic constraints such as recycling opportunities, resource and mineral supplies, waste treatment capabilities, and climate goals for PV development.
Solar panels have a life span of 25–30 years, and developing recycling processes to recover the strategic materials is critical considering the expected volume of photovoltaic waste in
4.3 Before disposing of waste photovoltaic equipment, the type, specifications, structure, and characteristic pollutants should be considered, and corresponding disposal plans should be
Yet PV has not been designed with recycling at EOL in mind, and it presents challenges to returning embodied raw materials back to use in new products through recycling.
For instance, in Nigeria, the absence of formal e-waste legislation and a dedicated PV waste recycling framework has led to the uncontrolled accumulation of imported second-hand solar
Studies from various countries have employed diverse methodologies to estimate EoL PV panel waste within specific national contexts.
Through implementation of the WEEE Directive, Europe has created the first mandatory market for PV module recycling including the development of PV-specific waste handling and
With solar panels having a 25-year lifespan, end-of-life (EoL) PV waste is expected to reach 78 million tons by 2050, posing a major environmental challenge without effective recycling.
This paper reviewed the recycling technology of end-of-life photovoltaic panels, including the development, types and structure of photovoltaic panels, the removal of EVA, the separation of
