Enzymes are stable, biodegradeable and environmentally friendly
Enzymes work at low temperature and moderate pH and are far more stable catalysts than other chemicals or biological molecules, making them the most environmentally-friendly solution for industrial manufacturing. Enzymes are biodegradeable, and keep on working until they are dissolved, usually by other enzymes.
Enzymes do not become part of the final product of the biochemical reaction which they are catalyzing. When the biochemical reaction is over, the enzyme is ready to effect the same reaction on another molecule again and again. Given the right conditions, the enzyme can go on and on for as long as needed. In some production processes, this lowers costs.
When industrial enzymes leave a production plant with the waste water, the used enzymes create no hazardous waste. They do not last long in the surrounding environment as they are broken down by microorganisms found in nature.
