Bio gas composter in vegetable markets to fuel public buses

Updated: Jun 18, 2022

Naturecalls Sustainability Solutions was established to give everyone a way to take direct climate action. But we do realize, before taking any action, education is important so we’re sharing a perfect circular economy case study to produce bio-CNG from vegetable waste generated every day in all cities at the vegetable markets.

Data showed, approximately 20-25 MTPD fruit and vegetable waste was generated on daily basis by the vegetable vendors in the market. Earlier, the waste made IMC incur heavy transportation and manpower costs as it had to be collected and transported to a centralized disposal site and waste disposal unit. Hence, the organization under its policy of promoting decentralized treatment of organic waste established Asia’s biggest Bio-CNG Plant of 20 MTPD capacity.

To create a circular system of vegetable commodification.

Take waste from vegetable markets - Dump all vegetable waste in the bio composter.

Composter will digest everything to give Bio CNG to fuel public buses and manure slurry for growing more organic vegetables. Also the digestion is fast and takes less than 24 hours for all waste to be converted to useful products making it a super profitable venture.

Key Highlights:

  • Tonnes of vegetable waste becomes Bio-CNG on a daily basis using the bio-methanation process instead of reaching the land fills and mixing with other dry garbage which degrades the dry garbage as well.

  • Multiple public buses were fueled successfully in the first phase of the project.

  • The system first segregates the three types of gases – methane, carbon dioxide and hydrogen sulphide.

  • With the use of 1,000 kilos of bio-CNG on a daily basis, IMC can save Rs. 5,000 a day on the fuel expenses of these buses. Thus, saving about Rs. 1.5 lakhs a month.

  • There is no solid residue. Most of the input is converted into gas and the leftover is highly nutrient liquid manure.

  • Presently all the fruit and vegetable waste generated at multiple vegetable markets is being collected and processed in the Bio CNG plant.

To execute a project like this, it is imperative for the team to have utmost clarity and assertion. With years of experience, our team can seamlessly integrate circular principles that align with your ESG/CSR commitments and transformation.
