There are lots of waste and recycling terms not only used by Biffa but within the news, government legislation and around the workplace but do you know what they all mean? Check out Biffa's list of definitions on common waste and recycling terminology.

End of journey and waste facilities:

Anaerobic digestion - The breakdown of organic material, such as food waste, by micro-organisms in the absence of oxygen. The process produces biogas, a methane-rich gas that can be used as renewable energy. Biffa's flagship AD plant, Poplars produces enough renewable energy to power over 10,000 home as well as the local supermarket.

Commodities - Materials that can be traded on the market. Types of waste commodities include recycled paper, plastic pellets, metal and glass.

Energy from Waste (EfW) - The process of creating energy in the form of electricity or heat from the incineration of waste materials.

Fly-tipping - The illegal disposal of any waste onto land that does not have a licence to accept it such as public highways, footpaths or private property (other than the waste producer’s).

Gasification - A process that converts organic materials into carbon monoxide, hydrogen and carbon dioxide.

Green energy - The energy produced from a non-polluting source such as wind turbines or solar panels. See renewable energy.

Incineration - Thermal treatment of waste with or without the recovery of the combustion heat generated. See Energy from Waste (EfW)

In-vessel composting - The in-vessel composting (IVC) process mixes organic material, including food waste, under strictly-controlled environmental conditions within a sealed and fully enclosed purpose-built container.

Landfill - Used for the disposal оf unrecyclable waste аnd rеfuѕе where no other waste process can be utilised. Wаѕtе іѕ burіеd іn ехсаvаtеd ріtѕ whісh аrе uѕuаllу соvеrеd wіth ѕоіl once full.

Litter - Usually small amounts of consumer waste left in an open or public place such as wrappers, cigarette butts and chewing gum.

Material Recycling Facility (MRF) - A facility designed specifically to receive, separate and prepare recyclable materials for marketing to end-user manufacturers, such as paper, cardboard, plastic bottles and containers, aluminium and steel cans. Discover what happens to waste at one of Biffa’s Material Recycling Facilities (MRFs).
