The Bioremediation Technology Area focuses on basic and applied research on microbial resources for biotechnological intervention to address environmental pollution from various industries. The activities of bioremediation area are focused to clean up oil spills on land, Oily ETP and tank bottom waste, oil contaminated soil, oil contaminated pond and sea water, oil contaminated drill cuttings, synthetic oil based mud waste, and other type of contamination like pesticide contamination to name one by using specific microbial consortium like Oilzapper , Oilivorous – S , Oilivorous - A , KT – Oilzapper, and so on.

The The Area is involved in the bioremediation of sites contaminated with crude oil spills and the treatment of oily sludge (hydrocarbon waste generated by oil refineries) using 'Oilzapper', a bacterial consortium, which can biodegrade different types of crude oil and oily sludge. The end product of bioremediation is CO2, water, and dead biomass, hence the process is very much environment friendly. Oilzapper has been in use since 1997 to treat oily sludge and clean up crude oil spills. So far, approximately 1 30 000 metric tonnes of oily sludge/ oil contaminated soil has been treated through this process. The various types of oil contamination are crude oily sludge, oil contaminated sites (lands and lakes), oil contaminated drill cuttings, SOBM (synthetic oil based muds), emulsion oily sludge, acidic oily sludge, high sulfur containing oily sludge, oil contaminated spent clay, and so on, which can be bioremediated by using Oilzapper technology. The microbes have been demonstrated very successfully in all the oil companies including Hindustan Oil Corporation Limited (refineries and depots), Bharat Oil Corporation Limited (refineries and depots), Indian Oil Corporation Limited (Refineries and depots), Oil and Natural Gas Commission (Ankleshawar, Ahmedabad, Assam, Cauvery, Meshana assets, and Uran plant), Cairn Energy Ltd, BG Exploration and Production India Ltd, Tata power in various parts of the country.
The area has set up one pilot scale bioreactor facility at TERI Gram, Gual
Pahari, with the support of DBT (Department of Biotechnology), Government of
India, and the following oil industries.
Indian Oil Corporation Ltd
Oil and Natural Gas Corporation Ltd
Bharat Petroleum Corporation Ltd
Hindustan Petroleum Corporation Ltd
Oil Industry Development Board
With this facility TERI will be able to provide the required quantity of Oilzapper, Oilivorous-S, and Oilivorous A for bioremediation of the oil spills and oil contaminated sites at the various oil industry locations in India.
TERI also intends to utilize the proposed facility in research and development
and commercial scale demonstration as well as in imparting training and human
resource development. Training imparted by working in the proposed fermentation
set up will further enhance the manpower expertise for application and operation
of high volume fermentation processes.

With the encouraging success of technology in bioremediation area a joint venture known as OTBL (ONGC TERI Biotech Limited) between ONGC and TERI was created for clean up of oil spills, oily sludge, oil contaminated site, and oil contaminated water <http://www.otbl.co.in>.
The Area initiated a program for the creation of a referral centre for microorganisms that could degrade toxic hydrocarbon compounds and desulphurize fuel oil. It also undertook a programme to assess and document microbial diversity at sites contaminated with toxic organic pollutants.
In addition, the Area has initiated programmes for detoxifying and removing recalcitrant pesticide residues in the environment. Microbes are used to develop a bioremediation technology to degrade chlorinated and nitro-aromatic pesticide residues.Areas of Expertise
