Glossary

aerobic
uses oxygen
 
anaerobic
does not use oxygen
 
anaerobic digestion
the turning of organic waste into soil conditioner using the process of biodegradation without oxygen
 
Best Practical Environmental Option (BPEO)
the most cost-effective and environmentally- friendly solution

biodegradable
can be broken down by a the natural process of decomposition by bacteria and other microorganisms

Biodegradable Municipal Waste (BMW):
the portion of Municipal Solid Waste which can be broken down by bacteria and other microorganisms.

compost: to turn organic waste into soil conditioner using the process of biodegradation.

Energy from Waste (EfW)
energy that is recovered by burning or otherwise treating waste
 
gasification
turning into gas; thermal treatment of waste to recover energy - the waste is heated to between 800 and 1400 degrees C, in the presence of oxygen
 
green waste
organic waste from the garden
 
incineration
burning
 
inert waste
waste that is not active, that is, it does not decompose or otherwise change
 
landfill
the method of disposing of waste by burying it under the ground
 
Materials Reclamation Facility (MRF):
plant where materials are separated and baled and then sent for recycling.
 
methane
CH4 - a smelly gas that contributes to the greenhouse effect

Municipal Solid Waste (MSW): solid waste that is collected by or on behalf of a Local Authority.

non-inert waste
waste that is active, that it, it does change or decompose
 
organic waste
refuse that is biodegradable
 
polluter pays
principle by which one who produces pollution (including waste) is made responsible for it.
 
pyrolysis
breakdown by heat; thermal treatment of waste to recover energy - the waste is heated to between 400 and 800 degrees C, in the absence of oxygen, and a mixture of gas, solid and liquid fuel is produced
 
recycling
breaking down something to make something new from the material
 
soil conditioner
product which improves the condition of soil
 
sustainable
a way of life, behaviour or practice which can be maintained indefinitely, e.g. without using up finite resources.
 
sustainable development
development that can be maintained in the long term, that is without consuming or destroying finite resources.
 
thermal treatment
treatment by heat - in terms of waste, this includes, incineration, pyrolysis and gasification
 
waste hierarchy
Reduce, Reuse, Recycle - the order in which we should try to deal with waste before we dispose of it.
 
waste minimization
the process of reducing the amount of waste that is disposed of
