Post Use Plastic Scrap Recycling

摘要

Plastics are used in a wide range of applications and some plastics items,such as food packaging,become waste only a short time after purchase.Other plastic items lend themselves to be reused many times over.Reusing plastic is preferable to recycling as it uses less energy and fewer resources.Long life,multi-trip plastics packaging has become more widespread in recent years,replacing less durable and single-trip alternatives,so reducing waste.For example,the major supermarkets have increased their use of returnable plastic crates for transport and display purposes four-fold from 8.5 million in 1992 to an estimated 35.8 million in 2002.They usually last up to 20 years and can be recycled at the end of their useful life.
