Can PVC be made from recycled plastic?
Thermoplastics are plastics that can be re-melted and re-molded into new products, therefore, recycled. Thermoset plastics are cross-linked to form an irreversible chemical bond. They cannot be re-formed and are non-recyclable. PVC, for example, is a thermoplastic material.
Can windows be made of recycled materials?
