Consider both the Quantity and Quality of Waste
 
Even waste that is able to decompose safely, and is not toxic to humans, can still be a problem if it occurs in excessively high quantities. Too much of a good thing can become a bad thing!
 
Education of the general population is an important way of protecting the environment from the negative impacts of both safe waste, and more dangerous waste.
 
Where potentially dangerous chemicals are required in a household only the minimum amount should be kept.  They need to be stored and disposed of in a safe manner.  Dangerous household chemicals should not be disposed in the garbage, burned, buried, or poured down the sewer without processing. 
 
Storage, usage and disposal of dangerous chemicals can be regulated by various authorities, be they local, national or international.
 
Disposal and processing of dangerous wastes is conducted by special organisations. Processing of dangerous waste can start with mechanical conversion of waste form one form to another (e.g. disassembling spray cans or mercury lamps). 
 
The aim of processing is to convert dangerous waste into non-dangerous material that can be safely disposed using one of four methods depending on the laws and regulations in your area:
  • Sewer;
  • Landfill;
  • Recycling centre;
  • Combustion.
