Selective collection and recycling

Selective collection -  is  one  of  the  recycling  stages,  together  with  the separation and with the processing of some waste compounds, in order to transform them into useful products.

Recycling -  is  the  process  that  reuses  old  products  and  materials  in  order  to produce and create new ones, without resorting to new raw materials.

Thus  reducing  both  the  energy  consumption  necessary  to  extract  the  raw materials  and  to  destroy  the  waste,  and  also  the  excessive  use  of  natural resources.

Environmental  pollution  is  defined  as  the  undesirable  change  in  physical, chemical and biological characteristics of our air, land and water.

Pollutants are generally grouped under two classes:

(a) Biodegradable pollutants - Biodegradable pollutants are broken down by the activity of micro-organisms and enter into the biogeochemical cycles. Examples of such pollutants are domestic waste products, urine and faucal matter, sewage, agricultural residue, paper, wood and cloth etc.

(b) Non- Biodegradable pollutants - Non-biodegradable pollutants are stronger chemical bondage, do not break down into simpler and harmless products. These include various insecticides and other pesticides, mercury, lead, arsenic, aluminum, plastics, radioactive waste etc.
