1 BIOTECH - Innovative scheme turns food waste into gas for cooking and electricity.
In 1994, driven by a desire to see an end to the dumping of waste in public places, Saji Das set up BIOTECH to focus on ways of managing organic waste to produce alternative sources of energy. Four years later BIOTECH launched its innovative biogas programme which uses unwanted food waste and other organic waste to produce gas for cooking and, in some cases, to produce electricity.
In order to have a real impact on the waste problem in Kerala and to produce significant amounts of clean energy, BIOTECH has developed biogas digesters that are not only suitable for domestic use but also for schools and hostels and larger municipal sites. To date BIOTECH has built and installed 12,000 domestic plants, 220 institutional plants and 17 municipal plants that uses waste from the municipal fish markets to produce biogas which is then used in a 3kW engine to generate electricity for lighting the market.
