Treatment of toxic wastes before they reach environment

Many of the above technologies used for decontaminating the contaminated sites can also be used for the treatment of toxic wastes, before they reach the environment. This is easier, since with the knowledge about the toxic wastes, it is easier to control the conditions of treatment. This will also prove to be more cost-effective for the industry.

In this method, biodegradable waste from an industrial facility can be treated in line using a bioreactor, which is inoculated with contaminant-degrading bacteria. The treated effluent may then be discharged to an appropriate outlet (e.g. sewer). Another similar example is the use of grease eating bacteria in grease traps at restaurants, rather than using caustic chemical or mechanical force to break up grease clogs
