Phenolics are seldom used in general consumer products today, due to the cost and complexity of production and their brittle nature.

Biotechnology ( sometimes shortened to " biotech ") is the use of living systems and organisms to develop or make useful products, and it is usually seen in agriculture, food production and medicine production.

In simpler term, Biotechnology is the research and development in the laboratory that involves bioinformatics for exploration, extraction, exploitation and production from any living organisms and any source of biomass by means of biochemical engineering where high value-added products could be planned ( reproduced by Biosynthesis, for example ), fore-casted, formulated, developed, manufactured and marketed for the purpose of sustainable operations ( for the return from bottomless initial investment on R & D ) and gaining durable patents rights ( for exclusives rights for sales, and prior to this to receive national and international approval from the results on animal experiment and human experiment, especially on the pharmaceutical branch of biotechnology to prevent any undetected side-effects on safety concerns by using the products ), for more about the biotechnology industry, see.

Biotechnology has applications in four major industrial areas, including health care ( medical ), crop production and agriculture, non food ( industrial ) uses of crops and other products ( e. g. biodegradable plastics, vegetable oil, biofuels ), and environmental uses.
