Compost
Compost is an organic material that can be added in soils
to increase the fertility and nutrient content of the soil
or as a medium to grow plants. Mature compost is a stable
material with humus that is dark brown or black and has a
soil-like, earthy smell. It is formed by the process of
composting, combining organic wastes (e.g., garden wastes,
food wastes, manures) in proper ratios into piles, rows, or
vessels; adding materials such as wood chips,etc. which are
necessary to accelerate the breakdown of organic materials;
and allowing the finished material to fully stabilize and
mature through a curing process. The compost has many
advantages: it increases the fertility of soil by increasing
the nutrient content of the soil, reduces the need of
fertilizers and pesticides, compost can bind heavy metals
and prevents them from migrating to water resources or being
absorbed by plants, prevents soil erosion, has been found to
protect plants from certain pests and disease and also it
may be used cost-effectively to remediate soils contaminated
by hazardous waste.
Recycled paper and related products
Paper along with cardboard forms the second biggest
component of domestic wastes after organic waste; about 13
percent of the total domestic solid wastes. Therefore
recycling of paper not only reduces the demand for cutting
of trees and use of energy but also helps in solving the
littering problem in the city and around dumping sites.
Various paper based items such as books, magazines,
newspapers, wrapping paper, cardboards, cartons, etc can all
be recycled into new useful products like hand-made paper,
filter papers, merchandise packing, decorative items, etc.
