Recycled poly(ethylene terephthalate), PET, mainly recovered from plastic beverage bottles, can be used to produce unsaturated polyester resins. Polymer concrete (PC) made with these resins has been investigated for potential use in construction and structural applications. Resins using recycled PET offer the possibility of a lower source cost of materials for making useful PC-based products. The recycling of PET in PC would also help solve some of the solid waste problem posed by plastics and save energy.
