Bio Digesters


  • CbS with support of technology, developed and approved by DRDO Ministry of Defence has offered an innovative technology for disposal of human waste in an eco-friendly manner.
  • These Bio Digesters can function at any atmospheric temp between -40⁰C to 45⁰C.
  • The bacterial consortium degrades night soil at temp as low as -40⁰C and produces colorless, odorless, inflammable biogas contacting 50-70% methane.
  • Bio-digester can be designed of mild steel and Fiber Reinforced Plastic (FRP).
  • Bio-digesters are cylindrical or square in structure with the provision of inlet for human waste and outlet for Biogas. Temp in these bio digesters is maintained between 5 ⁰C-30 ⁰C.
  • A person can use the toilet which is connected to the bio-digester. Night soil degradation occurs through microbial reaction which converts it into biogas.
  • The smell of night soil, the disease causing organism in the night soil and the soil matter are almost eliminated. On dry weight basis 90% of the solid waste is reduced.
  • The gaseous effluent (biogas) is continuously left off to the atmosphere.
  • Biogas can be used for various energy incentive activities like cooking, water and room heating.
  • Liquid effluent can be drained to any surface or soak pit without any environmental hazards.

We provide a huge range of Bio-Digester Tanks according to the size or customization demanded.
