- the use of living organisms or their products to degrade wastes into less toxic or non-toxic products and to concentrate and immobilize toxic elements, such as heavy metals. Bioremediation may be employed either on site or in bioreactors, using either native organisms or newly introduced ones, including genetically engineered varieties. The choice of organisms and treatments is determined by the nature of the toxic material and the biological and physical characteristics of the affected system.
- Use of living organisms to clean up oil spills or remove other pollutants from soil, water, or wastewater; use of organisms such as non-harmful insects to remove agricultural pests or counteract diseases of trees, plants, and garden soil.
