About the Organization

Every human activity generates waste and yet management of the waste is left as an afterthought and not made an integral part of our planning.

At Saahas, we believe that it is time human systems mimic natural systems where Nothing Is Waste! Saahas plays the role of an enabler in India’s path towards Circular Economy and we help build holistic and scientific solutions to reduce and manage solid waste based on the principles of Circular Economy.

We believe in integrating decentralization and localized climate action into larger, systemic changes and our programs focus on building Sustainable Communities, Resilient Cities and Villages, Rejuvenated Land and Water Bodies and Capacitated Governance Systems

About the Proposal

Saahas invites Request for Proposal (RFP) from qualified and experienced bidders to submit proposals for the Design, Supply, Installation, and Commissioning (DSIC) of a 1500 kg/day biogas plant based on organic kitchen and food waste.

The project aims to create sustainable and state-of-the-art facility that:

• Efficiently process primary segregated kitchen waste from urban sources,
• Generate clean biogas for cooking application.
• Provide nutrient-rich slurry for use as organic fertilizer,
• Minimize carbon emissions and maximize circular economy outcomes.

Scope of Work (SOW) & Responsibility:

The selected bidder shall be responsible for the end-to-end execution of the biogas plant project, including but not limited to:

Setting up the 1500 kg Capacity Biogas Plant: This solution will encompass the entire waste management process, including secondary segregation, efficient waste digestion for biogas production, and environmentally friendly disposal of by-products and remaining materials.

• Design & Engineering
• Preparation and submission of detailed plant layout, PFD (Process Flow Diagram), and P&ID.
• Engineering design of digester, gas handling, storage, and utilization systems.
• Civil, electrical, mechanical, and instrumentation design.
• Procurement & Supply
• Supply of all plant equipment including digesters, gas storage, piping, gas analyser, flow meters, safety devices, and control systems.
• Auxiliary systems: feed handling, slurry management, flare system and safety equipment.
• Safe transportation of all equipment to site.
• Civil & Structural Works
• Contractor shall consider and quote for all civil work required for the plant. Site will be provided with proper leveling.
• Installation & Commissioning
• Mechanical, electrical, and instrumentation installation.
• Integration of gas flow meters and gas analyser.
• The contractor shall comply with all the relevant environmental laws. Necessary emission control mechanisms shall be adopted by the contractor. The technology used shall not emanate foul smell and disturb the environment.
• Trial runs and commissioning (defined in detail in point 20 in General Requirement section).
• Preparation of as-built drawings and commissioning reports.
• Operations & Maintenance
• The proposal should clearly outline the operational requirements including water, electricity, communication, manpower etc. to run the site.
• Carbon savings from the output vs. inputs needs to be calculated and shown.
• Equivalence table of different fuels vs. biogas including PNG, LPG and CNF as observed Practically through experience.

Note - Requirement for commissioning of plant: The contractor shall submit the details of land, water and electricity requirements for setting up the plant.

Salient features of the offered plant:

General Requirements:

• The RFP is for the Design, Supply, Installation, testing and commissioning of a Biogas plant with a nominal capacity of 1500 kg/day of purely biodegradable (wet waste) material. The plant shall run in full capacity and capable of achieving the daily throughput of 1500 kg/day as specified above. It is the contractor’s obligation to size the equipment in accordance with the operating requirements of the plant.
• The plot available for installation of the Biogas plant is 1600sq ft approx.
• The system should be designed for minimal manual intervention and ensure efficient operation in the longer run, taking advantage of the natural processes involved.
• The system should not generate any bad odour, pollution and further garbage. The system should be eco-friendly and harmless to humans and animals.
• The Biogas plant shall comprise a digester designed for anaerobic decomposition of the slurry. The slurry will be pumped into the digester, where the organic material will undergo the process of anaerobic digestion, resulting in the generation of biogas. The biogas produced should be automatically stored in a balloon through a piping system. The Biogas will further be compressed & utilized as cooking gas to be used in the kitchen of the building with required pressure.
• The Digester where the anaerobic digestion takes place shall be leak proof made in Mild Steel. No leachate generated shall leak onto the floor.
• The equipment shall include a crusher/hammer mill specifically designed for converting food/kitchen/ wet waste into slurry.
• Any Mild Steel parts that form part of the plant shall have appropriate FRP/ epoxy coat to reduce corrosion problems.
• The other parts of the system will include compressor, gas storage, gas flow meter, control panel, solid liquid separator, Feed Tank and Slurry storage tank etc.
• The plant will be equipped with a 4 -6 burner and a pipeline extending up to 250 -400 meters for cooking purposes.
• The biogas plant shall include a gas capture system to effectively collect the gases generated during the digestion process. The inherent design of the plant must ensure the containment and utilisation of the biogas, eliminating any potential odour-related concerns.
• The machine shall have both visual and audible warnings that would help the user notice the fault and take immediate action. The crusher used for making slurry, the feeding system and any components should have the necessary safety features.
• The biogas plant equipment shall ensure reliable, pathogen-free biogas production within the desired timeframe.
• The contractor must ensure that all biodegradable material fed into the biogas plant is properly treated, and that there is no short-circuiting between the raw material and the biogas produced.
• Any exposed metallic components forming part of the system shall either be adequately coated.
• Any electrical boards attached to the outer structure of the biogas plant shall have an IP65 rating.
• Hardware info, manuals, and schematics of connection cables shall be provided either on a CD or in a printed manual format.
• The biogas plant shall include easy access for cleaning and maintenance purposes, ensuring efficient maintenance of the system surface.
• The successful contractor shall be responsible for the installation and commissioning of the equipment and shall provide all technical assistance required during the operation of the Biogas Plant unit installed.
• Commissioning will be considered as successful only when the machine proves that: i. One single plant can treat 1200 KG (organic waste) per day; ii. The manure produced shall comply with FCO norms; iii. Efficient Biogas generation is achieved from the plant.

Eligibility

Bidders must meet the following eligibility conditions:

• Experience:
• The bidder should have successfully installed and commissioned at least 10 biogas plants in India.
• Out of these, at least 3 plants of capacity 1 TPD or above must be commissioned based on organic kitchen waste.
• The bidder should currently operate at least 3 plants in North /Central India.
• Financial Strength:
• The bidder should have had a minimum turnover of INR 5 Crores or above in each of the last three financial years (audited statements to be submitted).
• Legal Compliance:
• The bidder must be a registered legal entity in India and comply with all statutory and regulatory requirements. (Details like , Company Registration, Legal Status, PAN, TIN, GST, Bank details, Quality Certifications need to be submitted).
