Use of renewable sources of energy, some refuse from

plant material and animal waste have been exploited as re-

sources to provide fuel, light and heat energy e.g. sugarcane

and cotton seeds residues are used as fuel. In this way, trees,

oil or coal are preserved.

*r
Metal wastes, garbage and plastic materials can be recycled

and used instead of new materials. This saves volumes of new

raw materials.
