Environmental Science

1. Recycling material into a product of lesser quality
4. The process of generating energy in the form of electricity or heat from the primary treatment of waste
9. A measure of the cleanliness of the air and its impact on health
11. A recycling process where all recyclables are mixed together and sorted at a facility
13. The process of turning organic waste into nutrient-rich soil
15. Process of converting waste into reusable material
18. Variety of life in an ecosystem
20. Natural home of an organism
23. Transforming waste materials into new, higher-quality products
24. These materials include some type of electronic component and are most often disassembled in order to be recycled

2. Often used to make biofuels such as ethanol.
3. Lightweight, durable material often used in turbine blades for capturing wind energy.
5. Meeting needs without compromising future generations
6. Community of interacting organisms and their environment
7. Contamination of the natural environment
8. Energy harnessed from the internal motions of ocean waters
10. To decrease the amount of waste produced
11. Wastewater that needs to be treated before being released into the environment
12. Plants cultivated specifically for energy production.
14. Energy derived from heat stored beneath the earth's surface.
16. Protection and preservation of natural resources
17. Organic material that can be recycled into fertilizer
19. Plastics that can be melted and reshaped multiple times, making them ideal for recycling
21. Material discarded after it has served its intended use by a consumer
22. Soda cans are made of this material
