Answer:
You can actually do waste management on a commercial scale. This is with regard to solid urban waste.
You will notice that when segregated, waste materials fetch fixed prices in the market. For eg. plastic bags fetch about Rs.7/- per kg. Waste paper gets Rs.6/- cardboard fetches about Rs.12/-, scrap steel fetches about Rs.15/-, aluminium Rs.60/- and copper Rs,300/-. Rubber waste also has a price. PET bottles also fetch about Rs.10/- a kg.
What requires to be done is get a batch of rag pickers or even unskilled labourers, hire a mini truck on a daily basis and get these guys to collect all man made materials that are suitable for recycling. Normally a person collects about 20 kg of waste and carries it on his back over huge distances to reach the trash buyer and sells it. In this case because the workers are followed by a goods vehicle, they can collect 200 kg of waste a day each.
The waste must be segregated. The stuff that is segregated will fetch an average price of Rs.7/- a kg. Assuming that you have 5 persons for collection and another two for segregation, it will cost you Rs.3500/- in labour charges at the rate of Rs.500/- per head per day
. The van will cost you about Rs.2000/- for a day because running will be within about 50 km per day. That should leave you with Rs.1500/- as profit. In fact it will be more because when everything possible is collected there will be some metals and other materials as well that will fetch a better price.
You will need a place for segregation. You can even ask municipal trucks to dump their waste in your segregation unit and pay them a thousand or two for a truck load. In this case you will get about 20% of recyclable materials and about 80% of organic waste. This can be used to make compost with the help of a bit of farm yard manure, poultry manure and such other animal wastes. Compost sells for Rs.4/- to Rs.5/- per kg.
Segregated materials can be sold to bulk dealers and that will fetch you better prices. In my view segregation of normal urban waste will give you a profit of Rs.1000/-to Rs.1500/- per ton of waste segregated.
If done efficiently this can be a profitable business as well as serve as a boon to society.
