Types of wet waste (NH) in hyderabad: Process optimization
Currently 1 operator working on 8hrs basis.
Expected 100kgs of composting /day.
AMC by Vennar Organic composting
Food waste – 78 kgs/day Garden Waste – 300 kgs/day
Cost saving and ROI
Garden waste generated in site per month approx. - 10 tractor tripsPer trip cost is Rs.850/-Approx. cost per month is 10*850 = 8,500/-Approx. cost per annum is 8,500*12 = 102,000/-Composting Manure generation – 400 kg /month –Rs 10 kg –4000, Per year Rs 48000Investment Rs 8.25 lacsROI – 4.8 years
Benefits of organic waste converters
• Large quantity of solid waste is converted to fertilizer in a very short period. • Fertilizers can be used for gardening in site.• Machine requires less space and the efficiency is high • Manpower and maintenance is very less • This is one of the latest techniques of managing solid waste.
