This PPP project is a BOOT basis project for a period of 20 years and has been approved under Jawaharlal Nehru Urban Renewal Mission (JNNURM) scheme of the Govt. of India.  

Tatva has done development, design, engineering, finance, construction, implementation, operation and maintenance of: transfer stations, transportation of Municipal Solid Waste (MSW) from transfer station to waste processing & disposal site, closure of existing dumpsites, and processing & disposal facility of treating 400 tons of waste generated from Coimbatore in the State of Tamil Nadu.

For the Coimbatore projects waste dumpsites have been created at:

Tatva has executed the project of development, maintenance & operation of waste processing for a period of 3 years for CIDCO, at Chal near Taloja MIDC, as per MSW Rules 2000 on a BOOT Basis. Tatva has utilized the Windrow Technology for Composting. The capacity of the compost plant is 55 MT per day & for the landfill is 15.5 years with a total area of 14 hectares.

Tatva is executing a project for providing, testing, and commissioning of 100 TPD Municipal Solid Waste (MSW) compost plant and Vermi composting in Jodhpur, Rajasthan on BOOT basis. With a total area of 48 acres to work with, Tatva will be using Windrow Technology and Vermiculture for the project.  The project will include providing all mechanical, electrical, hydraulic accessories etc., including 5 years of operation & maintenance.

The project was awarded to a consortium, which formed a Special purpose vehicle (SPV) by the name of "Tatva Global Environment (Deonar) Limited" to execute this Integrated Waste Management facility in Deonar, Mumbai.

The existing landfill at Deonar covers a total of 132 hectares, of which approximately 120 hectares have been used for waste disposal. The overall management plan for site has the following components:

Tatva's activities in Deonar consist of

• Operation and Maintenance of all the processing facilities and partial closure area throughout the period of concession of 25 years.
• Partial closure within 2 years while continuing to receive Municipal Solid Waste (MSW) to the tune of 5,500 TPD and silt at the rate of 9,000 TPD (6,000 cum) per day for 75 days during the first year.
• Creating basic infrastructure and undertaking site development works such as peripheral bund, boundary wall/fencing, roads, storm water drains, water supply, electrification, office building, landscaping, etc.
• Creating a new MSW processing facility (composting technology or its variant) with leachate collection and primary treatment facility (centralized).
• Creating two separate landfill facilities for: (i) disposal of rejects from the processing facility (ii) emergency operation by MCGM. It is anticipated that the leachate from all the two landfill facilities will be treated on-site in a centralized primary treatment facility. Emergency landfill will be designed in a manner such that after 3 years of operations, it can be integrated with the landfill for receiving rejects.
