An entire branch of biotechnology, known as 'white biotechnology', is devoted to this. It uses living cells—from yeast, moulds, bacteria and plants—and enzymes to synthesize products that are easily degradable, require less energy and create less waste during their production. This is not a recent development: in fact, biotechnology has been contributing to industrial processes for some time.

For decades, bacterial enzymes have been used widely in food manufacturing and as active ingredients in washing powders to reduce the amount of artificial surfactants. Transgenic Escherichia coli are used to produce human insulin in large-scale fermentation tanks. Good book know all about Biotechnology
