We at Green 4 India, are committed to offering solutions for processing of Municipal Solid Waste into useful by products. The non-biodegradable waste like plastics, textiles, broken furniture, carpets, old tyres .... have to be processed into refuse derived fluff, which encounters many challenges.
It starts with separation of plastics to restrict the quantity (not more than 5%), shredding of different constituents of non-biodegredable waste in the most economical manner to make it a sustainable byproduct in the market. Green 4 India has developed air classifier which separates light plastic particles from other dense materials, where the content of plastic allowed can be controlled.
Green 4 India's research group with year's of field trials has successfully developed a special shredder to shred the materials as per customer needs of -40 mm to -100 mm with a unique single pass shredding resulting in the lowest power cost per ton of waste conversion. The challenge continuous to removal of moisture content in the refuse derived fuel and screening out fine silica content. Green 4 India's existing product line of special screening equipment and rotary dryers are integrated into the system to eliminate silica and to down the moisture from 30% to 20% which increases the calorific value to 3000 - 3200 K.cals.
This process calls for a heat value of 10,000 kJ/kg to dry the material which makes it expensive to be carried out at the MSW processing facility. Green 4 India suggests to install these systems at the cement plants where waste heat available can be utilized at no much extra cost. The refuse derived fuel can be used by cement plants as an alternate fuel to coal. It also best fits into as an alternate to Biomass fuels which have become expensive over a period of time, making the Biomass power plants unsustainable with the power tariffs fixed by the government. There are various methods of increasing the calorific value of the refuse derived fuel and Green 4 India with its expertise, offers these solutions.
