Useful
Wastes:
The two main useful wastes are Cow dung and Press mud.
Cow dung is utilised for producing biogas and the used
dung slurry is reused as manure. Press mud on the
other hand is a waste obtained during the manufacture
of cane sugar and is a valuable manure used in dry
lands as it conserves the moisture and releases plant
nutrients.
Recycling
Recycling is utilizing wastes as raw materials in the
manufacturing of new products. Wallboard, organic
fertilizer and cellulose plastics are some end
products of recycling. Recycling has two distinct
advantages:
-
Recycling
conserves existing natural resources. For instance
recovery of 1 tonne of paper saves 17 trees from
the axe, and are the virgin sources of paper.
-
Sufficient
reduction in the volume of waste.
