Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

The three main types of recycling are mechanical recycling, chemical recycling, and energy recovery. Mechanical recycling involves physically breaking down waste materials into smaller pieces, while chemical recycling involves using chemical processes to convert waste materials into new materials. Energy recovery involves burning waste materials to generate electricity or heat.
