Resource detail

Researchers from Indian Institute of Technology Hyderabad (IIT-H) are developing algal-bacterial hybrid systems that help treat waste water while enabling biodiesel production. The immediate intended beneficiaries of the research are gated urban communities that have in-house plants for treating sewage. The team primarily focuses on treatment of domestic sewage and its components like those originating from kitchen and laundry. Currently, sewage treatment facilities in the country can only treat about 26 billion litres per day. The unavailability of an extensive centralised system of waste water treatment has led to the discharge of untreated water into water bodies and land, resulting in pollution and contamination.
