these days appartments are praticing of collecting degradable solid waste such as food, vegetables peals, fruits etc and storing it in a tank for 2 to 3 days by addind water and cowdung to it to decompose and for a manure. this manure is used for gardening within the gated community. it is heigenic also ..kids play in these garden and parks.
why cant we opt for a option wherein we can collect the segregated degradable waste from residential areas and form a manure and use it for the area parks and gardens... now the solid waste collection system is collecting waste from each area and disposing it in a common area for further treat.when we use it for area parks the collection burden is also less and the transportation cost is saved.

I'm working in ACC ltd Kymore Cement Works. Here we have started the same thing in our colony and also going to use vermicomposting technique.
But I would like that it will be done in cities also where RWAs can work together and implement this.

COMPOSTING:
Composting is controlled decomposition, the natural breakdown process of organic residues. Compost is easier to handle than manure and other raw organic materials, stores well and is Odor-free. Composting is an ancient technology, practiced today.
Composting is nature's way of recycling. Composting biodegrades organic waste. i.e. food waste, manure, leaves, grass trimmings, paper, wood, feathers, crop residue etc., and turns it into a valuable organic fertilizer.
Optimal conditions for rapid, aerobic composting
Condition Acceptable Ideal
C: N ratios of combined 20:1 to 40:1 25-35:1
Feedstocks
Moisture content 40-65% 45-60% by weight
Available oxygen >5% >10% or more
Concentration
Feedstock particle size < 1 inch Variable
Bulk density 1000 lbs. /cu yd 1000 lbs. /cu yd
pH 5.5-9.0 6.5-8.0
Temperature 110-150o F 130-140o F
(43-66o C.) (54-60o C).
The Composting Process:
Raw Finished
Water, Heat, CO2 Organic Matter

3. Water Microbes
4. Microorganisms
5. Oxygen Compost

Applying to Soil:
Compost should be applied to soil in the spring and summer so plants will get the benefit of the nutrients during the growing season.Compost can be either dug into the top 15-20 cms of soil (no deeper) or left on the surface to act as a mulch (make sure the soil is moist before doing this). It can be spread over soil surrounding established plants.
For use with shrubs, bedding plants, lawns, tubs and planters, vegetable patch, fruit plants, Potting compost.
As garden compost is so rich, it must be diluted before using it as a potting compost for raising seedlings. Use one part (by volume) of compost with one part of loam/good soil and one part leaf mould or coir.
The other technique is Vermicomposting:
Vermicomposting is a modified and specialized method ofcomposting- the process uses earthworms to eat and digest farm wastes and turn out high quality compost in two months or less. Vermicompost is not a biofertilizer as is touted by some, merely improved compost.
good idea. Where r u located? If you are in Delhi, we are organising seminar on waste management, which will have some focus on waste to organic fertiliser manufacturing: business opportunities
