Solid Waste Management

Solid Waste Management
Water treatment, Supply management and Non-revenue Water

Solid waste can broadly be classified into two categories. According to Indian MSW, Rules 2000 "Municipal Solid Waste" includes commercial and domestic wastes generated in a municipal or notified area in either solid or semi-solid form excluding industrial hazardous wastes but including treated bio-medical wastes. Solid waste also includes hazardous waste generated by various industries.

Municipal Solid Waste (MSW) can further be classified into biodegradable waste (such as food and kitchen waste); recyclable materials (such as paper, glass, bottles, metals and certain plastics) and domestic hazardous waste (such as medication, chemicals, light bulbs and batteries).

Solid waste management is one of the major challenges faced by many countries around the globe. Inadequate collection, recycling or treatment and uncontrolled disposal of waste in dumps can lead to severe hazards, such as health risks and environmental pollution.

The management of solid waste typically involves its collection, transport, processing and recycling or disposal.

Collection includes the gathering of solid waste and recyclable materials, and the transport of these materials, after collection, to the location where the collection vehicle is emptied. This location may be a material processing facility, a transfer station or a landfill disposal site.

Waste disposal today is done primarily by land filling or closure of existing dump sites. Modern sanitary landfills are not dumps; they are engineered facilities used for disposing of solid wastes on land without creating hazards to public health or safety, such as the breeding of insects and the contamination of ground water.

Why should solid waste be treated?
Tatva’s Water Treatment, Supply & Distribution Projects

The Ministry of Urban Development, in its manual on solid waste management (year 2000) has estimated country wide waste generation of 100,000 MT per day. Where does this tremendous amount of waste go? In India the segregation of waste is almost negligible. Municipal Solid Waste is dumped in a mixed form in an unscientific manner on open waste land or low lying areas even near creeks, forests, rivers, ponds and other ecological sensitive regions. This practice is commonly known as ‘Open dumping’/haphazard dumping and does not meet the norms of disposal specified in the MSW Rules.

These dumping grounds not only affect the environment by air, water and soil pollution but also damage the property in the vicinity. The presence of moisture and rainwater leach the pollutant chemicals produced during degradation to dissolve and flow into the groundwater reserve/sea/river thereby affecting the flora and fauna of the water body. The dump sites virtually become a breeding ground for all kinds of diseases. Besides this, it leads to formation of secondary pollutants like Hydrogen sulfide, methanethiol and other Hydro sulfurous gaseous pollutants reacting with bacteria present in the waste in the presence of moisture and temperature. Methane, which is one of such toxic gases produced, leads to fire hazards.

Dumped hazardous and biomedical chemicals also leak into waterways and aquifers, which pollute water and soils. Even dumped yard debris harms the environment. In metropolitan cities where the land cost is on high rise, by filling such mixed garbage in the low lying area near the creek and bringing it to a ground level helps the builders to construct the buildings for both residential and commercial houses and ignoring the adverse impact of garbage reaction underneath.

This project was awarded by the MCGM. The dumpsite is located in a western suburb of Mumbai, and is spread over an area of 19.6 hectares. When MCGM awarded the project, the total quantity of Municipal Solid Waste (MSW) and C&D (Construction & Debris) waste stored at the site was estimated to be 2.34 million tons.

The work done for the Gorai Project can be divided into two broad categories: (i) Work relating to the closure and capping of the Gorai dumpsite; and (ii) Work relating to the operation and maintenance of the capped dumpsite for a period of fifteen years.

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:



Total site area



34.52 acres



3.5 acres



643 acres


City Industrial Development Corporation (CIDCO), New Mumbai

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.

National Building Construction Corporation Limited (NBCC), New Delhi

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.

Deonar Municipal solid waste Project at Deonar, Mumbai.

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.
