| agriculture, mining, industry | solid wastes are generated by these |
| methane gas | microorganisms give off this when they decompose matter in a landfill |
| car batteries should be recycled | to prevent leakage of lead |
| source reduction | a process in which the amount of solid waste generated is reduced |
| incinerator | place where solid wastes are burned to produce eletricity |
| recycling | process of collecting, sorting, and processing waste materials to produce new materials or products |
