Definitions of the main concepts and variables

Biodegradables : Readily biologically degradable waste, mostly food waste and waste from production of food and feeding stuff.
Biogas production: Biogas refers to a mixture of different gases produced by the breakdown of organic matter in the absence of oxygen. Biogas can be produced from raw materials such as agricultural waste, manure, municipal waste, plant material, sewage, green waste or food waste.
Composting is a sort of aerobic biological treatment, i.e. decomposition of the waste by means of micro-organisms and in the presence of air.
Energy recovery is exploitation of the energy which is released during waste incineration.
Hazardous waste : Waste which requires special treatment according to Regulations Concerning Hazardous Waste, owing to its toxic or flammable Properties.
Landfilling is final disposal in an officially approved landfill.
Recycling (Material recovery) : processing and use of wastes in production and consumption processes
Reuse : Use of materials or products more than once, e.g. refilling of bottles
Waste handling is usually defined as everything which is done with the waste, from discarding to final disposal. The term treatment/disposal denotes processes which lead to physical or chemical transformation of the waste (material recovery/recycling, composting or incineration) or final disposal (landfilling, dumping, export and reuse).
