Waste Aware Fife - Glossary

Term
Description
  Aerate: expose to the air.
  Aerobic: uses oxygen.
  Anaerobic: does not use oxygen.
  Anaerobic digestion: the turning of organic waste into soil conditoner using the process of biodegration without oxygen.
  Best Practical Environmental
Option (BPEO):
the most cost-effective and environmentally-friendly solution.
  Biodegradable: can be broken down by a natural process of decompostition 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 biodegration.
  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 and vegetable waste, tea leaves, coffee grounds and egg shells.
  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.
  Leachate: water from a landfill site in which components of the waste have dissolved.
  Materials Reclamation Facility
(MRF):
plant where materials are seperated 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 is, it does change or decompose.
  Organic waste: refuse that is biodegradable.
  Polluter pays principle: 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: a product that improves the condition of the soil.
  Sustainable: a way of life, behaviour or practice that can be maintained indefinitely, i.e. without exhausting 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 minimisation: the process of reducing the amount of waste that is disposed.
