Recycled materials

Definition

Recycled materials are products that have been processed and repurposed from their original use, diverting waste from landfills and reducing the need for new raw materials. This practice not only conserves natural resources but also minimizes environmental impact and energy consumption associated with manufacturing new products. Utilizing recycled materials plays a significant role in making technologies, such as piezoelectric energy harvesting systems, more sustainable and cost-effective.
