Nisargruna technology has been developed at BARC for processing different types of biodegradable waste including kitchen waste, municipal solid waste, slaughter house waste, fruit industry waste etc. The technology has evolved in last several years and about 250 installations are operative in various parts of country.
The main aim of the NISARGRUNA plant is to pay back Nature's loan in the form in which NATURE will appreciate. This technology offers a comprehensive solution for handling the biodegradable waste material and employs "Zero garbage, zero effluent" method for waste disposal.
Biodegradable waste mostly comprises of food waste (38-40%) which can generate about 60 m3 of biogas (about 35-40 Kg methane) per ton of waste. This can be used as fuel for domestic purposes or generation of electricity.
Organic manure is another by-product of this technology. Manure is an important component of sustainable agriculture. Nisargruna Biogas manure obtained from biodegradable waste comprises a quantum of 10% of the total waste processed having carbon to nitrogen ratio of 12:1.

Advantages of NISARGRUNA technology:
•    This plant processes all types of biodegradable waste.
•    This plants uses mixer for homogenization of waste.
•    There is a biphasic separation of aerobic and anaerobic phases.
•    Thermophilic bacteria are developed at predigestor stage which enhances the degradation of waste.
•    Most of the effluent water is recycled which saves about 60% water.

•    Environment friendly disposal of biodegradable waste, which is the need of the hour considering mass pollution everywhere.
•    Generation of fairly good amount of fuel gas, which will support the dwindling energy resources,
•    Generation of high quality manure, which is an excellent soil conditioner. This is very important for replenishing the diminishing productivity of soils.
•    Employment generation
•    Environmental protection by helping in maintenance of elemental cycles in the nature.

1. Combination of aerobic and anaerobic phases for better performance.

2. Enhanced performance due to addition of hot water from solar heating system.

3. Enrichment of methane due to recycling of biogas

4. Recycling of water to the extent of 60% for gardening and other applications.

This technology is suitable for majority of biodegradable wastes including kitchen waste, food processing industry waste, Municipal solid waste, poultry waste, slaughter house waste, agriculture waste, dairy industry waste etc.
