How does recycling work?

ScienceLesson on requestFree to read

Quick answer

Recycling works by collecting used materials, sorting them by type, cleaning and processing them into raw material, and using that to make new products. It keeps resources in use and reduces waste, energy use, and pollution. Used items are collected and sorted by material (paper, glass, metal, plastic).

Step by step

  1. Used items are collected and sorted by material (paper, glass, metal, plastic).
  2. Each material is cleaned and broken down into raw form.
  3. That raw material is remade into new products.
  4. Not everything is recyclable, and contamination can spoil a batch.
