Bury your trash
In this online resource instructions are given for a long-term experiment in which students can learn about what happens to rubbish when it is buried.
Students bury various pieces of trash in a plotted area of land. After two to three months, they uncover the trash to investigate what types of materials biodegrade in soil.
Waste management engineers use the process of biodegredation to minimize the amount of space that landfills take up. Civil and agricultural engineers take advantage of the biodegradation process in designing waste and water treatment facilities and making soil improvements to improve crop production.
