The International Society for Environmental Biotechnology defines environmental biotechnology as "the development, use
and regulation of biological systems for remediation of contaminated environments (land, air, water), and for environment-friendly processes (green manufacturing technologies and sustainable development)".

Environmental biotechnolgy techniques involves TDS determination, Hardness testing of water, Biological Oxygen Demand (BOD), Chemical Oxygen Demand (COD) Dissolved Oxygen, Chlorine Estimation, Silver Estimation. Waste water treatment biorem edication.
