Landfilling vs. Recycling: Weighing the Environmental and Economic Trade-offs of Solar Panel Disposal

With the global proliferation of solar panels, the amount of solar panel waste has become a growing concern for the industry. The International Renewable Energy Agency (IRENA) currently estimates that if no aggressive measures are taken, solar panel waste could reach 60 million metric tons by 2050.

In tackling the challenge of solar panel disposal, the comparison of treatment methods for used solar panels reveals two prevalent approaches: landfilling and recycling. Landfilling involves discarding end-of-life solar panels at waste disposal sites. However, solar panels contain hazardous materials such as lead, cadmium, and selenium, which can leach into soil and waterways, polluting ecosystems and posing health risks. Furthermore, solar panels contain valuable materials such as silicon, silver, and aluminum. When discarded in landfills rather than recycled, these reusable components are lost, further wasting resources. In contrast, recycling harnesses advanced recycling technologies to recover valuable materials such as silicon, silver, and aluminum, considerably mitigating environmental impact and aiding resource conservation. Although currently more costly, recycling offers a sustainable pathway, aligning with renewable energy goals.

The comparison of treatment methods for used solar panels

Innovative technologies and approaches are transforming how solar panel disposal is managed, paving the way for more sustainable practices. Leading this transformation, companies like DOING are deploying advanced recycling technologies designed to efficiently extract valuable materials like silver and silicon for reuse. DOING's solar panel recycling equipment exemplifies this progress, turning environmental responsibility into a tangible economic opportunity.
