Plant Cycles: Photosynthesis & Transpiration
Engineers creatively make use of the plant kingdom for many beneficial human applications such as cleaning air and water. Phytoremediation is the engineered use of green plants to remove or render harmless soil or water contaminants including heavy metals, trace elements, organic compounds and radioactive compounds. For example, one company designed a series of engineered ecosystems at a highway rest area using plants, insects, snails and worms to clean the wastewater and recycle it back into the restrooms to flush toilets. Others have planted trees and vegetation as a low-tech and low-cost cleanup technology for contaminated soils, groundwater and wastewater.
