Environment and production

This page covers the following topics:

1. Polymers and the environment
2. Recycling polymers

Many polymers are non-biodegradable and so their disposal can cause a number of environmental issues. There are three main methods for disposing of polymers: recycling, landfill and burning.

Polymers and the environment

Recycling is one method of disposal for polymers. It has a number of advantages and is often preferred over disposal through landfill or burning. It does, however, also have some disadvantages.
