MUNICIPAL SOLID WASTE
Management of discarded wastes is now a challenging task in all the urban and semi-urban areas specially the task of prompt collection-transportation and disposal. The high organic matter containing materials known as biodegradable or green waste is highly susceptible to pathogenic bacterial invasion thereby causing mal-odors, diseases, smoke, fire and acidic leachates. Also, several other items such as metals, paper products, wood, plastic are getting lost in the garbage dumps thereby putting fresh demand on non-renewable petro products on one side and on the other side consuming costly land space in urban areas.
The approach described here is aimed at technological solutions for processing treatment of waste to recover various usable products such as compost, fuel pellets, recyclable materials like plastic, glass and metals to the maximum extent so as to minimize the burden on the landfill site and also to conserve the usable products, rather than destroying them in landfills or mass burn / incineration process.

M/s. Hydroair Tectonics (PCD) Ltd. is a leading project engineering company engaged in all types of Environment Engineering Projects especially in the field of Municipal Solid Waste Management. We are armed with more than 150 engineers working all over India for various environmental projects and have successfully completed more than 200 Environmental Projects

The Various Technologies have been applied for Integrated Municipal Solid waste Processing are as below.

Compliance with the MSW (M&H) Rules, 2000

Biodegradable Waste will be processed by composting only.
Compost or any other end products will comply with standards as specified in Schedule-IV of MSW (M&H) Rules, 2000.
Land filling shall be restricted to non-biodegradable, inert waste & other waste those are not suitable either for recycling or for biological processing.

Advantages of Integrated waste processing facilities:

1. Eco friendly and non polluting process in order to reduce the impact of dumping site in the adjacent areas.
2. Control of malodor and fly control measures.
3. Mechanical and manual segregation can separate the entire incoming MSW into various categories depending upon their usage, which would make the whole process more efficient.
4. Reducing the burden on landfill.
5. The rejects or by products from one process can be merged with other process in the integration of the technologies, which would lessen the burden on landfill.
6. Inert separation from composting usually takes away 5 to 7 percent of the compost that is recovered and added to compost thereby increasing the compost output.
7. Control of pH and EC.
8. In a non integrated facility only one third to one fifth of the collected waste is accepted for composting where the rest would be dumped in the landfill thus increasing the burden on the costly urban land.
9. Minimizing the generation of Leachate, gaseous matter, pathogens and reduction of SLF volume thereby involving lesser costs and economize on land use.
10. Treatment and consumption of Leachate through Bio-composting process.
11. Low cost environment friendly technological option for garbage treatment and disposal.

At Present we are executing the following MSW Processing Project-

1400 TPD Integrated MSW Processing Project with Power Generation Plant at Perungudi Dumping ground, near Chennai for Chennai Municipal Corporation.
750 TPD Integrated MSW Processing Project with Power Generation Plant at Turbhe, for Navi Mumbai Municipal Corporation.
300 TPD Integrated MSW Processing Project with three transfer stations at Pallavapuram, Tambaram & Alandur for Pallavapuram Municipality, Chennai.

Compost Processing Machinery
Refuse Derived Fuel Processing Machinery
Inert Processing to Eco Bricks

The Various Technologies have been applied for Integrated Municipal Solid waste Processing are as below.

Environmental Issues covered	:	Control of Mal-odors and toxic gaseous emissions Control of pathogens, flies, rodents and vultures. Control of Dusty Particulate matters Control of Smoke & Fire
Technology Relevance	:	Triple Eco-friendly It takes care of polluting putrescible matters Processing treatment itself is non-polluting Recover products namely organic manure to help in soil health building and RDF as a replacement of fossil fuel.
Recovered products from MSW	:	Soil friendly compost RDF Plastics/metals/Glass etc. Eco Bricks from Inert Processing Power generation from RDF
Compost and Potting Media	:	Highly useful for improving organic carbon content of soils and supplementation of trace element requirements. The product will be useful in improving the efficiency of fertilizers and conservation of moisture. Compost will be extremely useful as organic soil conditioner.

Compost Manufactured at Ichalkaranji MSW Processing Plant at Ichalkaranji, Maharashtra.

RDF– Green Coal

:

The lignitic content of MSW having high calorific value will be processed into green coal. This will be supplementing the fuel requirement from other sources. The calorific value of processed green coal will be 3200 to 3800 kcal/kg. Fixed Carbon 10 to 12% Sulfur content <0.70% and ash content of 20 to 25%.

Benefits to Urban Local Body

Compliance of MSW Rules 2000 & other regulatory aspects
Saving of cost on maintenance of disposal site;
Increasing the shelf life of disposal site by 6 folds;
Minimization of waste related litigations;
Hygienic working conditions for SWM workers;
Protection of aesthetic value of the city;
Project operation in eco friendly with international standards;
Integration of recovered product usage with national theme
Municipal Solid Waste will be treated in scientific manner as per MSW     Handling Rules 2000.
