| zabor-bilketarako ibilgailu | refuse collection vehicle (Special vehicles designed and equipped for the collection of wastes and their transportation to a waste disposal site) | |
| zabor-edukiontzi | waste bin (A container for litter, rubbish, etc.) | |
| zabortegi | waste dump (Area where wastes are deposited and burned) | |
| zabortegi | landfill (The oldest method of waste disposal for the solid matter discarded in the domestic dustbin, along with the packaging material and paper from high street shops and offices. Landfill sites are usually disused quarries and gravel pits. When they were filled, previous practice was to cover them up with soil and forget about them. Housing estates have been built, often with disastrous consequences, on old landfill dumps. Waste burial has now become a serious technology and a potential source of energy. Landfill sites can be designed to be bioreactors, which deliberately produce methane, gas as a source of biofuel or alternative energy. Traditionally, waste tips remained exposed to air and aerobic microbes - those which thrive in air - in order to turn some of the waste into compost. However, open tips also encourage vermin, smell in hot weather and disfigure the landscape. In the 1960s, as a tidier and safer option, landfill operators began to seal each day's waste in a clay cell. While excluding vermin, the clay also excluded air. Decomposition relied on anaerobic microbes, which die in air. However, the process produced methane (natural gas), which was a safety hazard. The methane is now extracted by sinking a network of perforated pipes into the site) | |
| zabortegi klandestino | uncontrolled dump (Place where waste is left on the ground and not buried in a hole) | |
| zabortegiko gas | landfill gas (Landfill gas is generated in landfill sites by the anaerobic decomposition of domestic refuse (municipal solid waste). It consists of a mixture of gases and is colourless with an offensive odour due to the traces of organosulphur compounds. Aside for its unpleasantness, it is highly dangerous as methane is explosive in concentrations in air between 5 per cent, the Lower Explosive Limit (LEL), and the Upper Explosive Limit (UEL) of 15 per cent. Landfill gas must be controlled at all operational landfill sites, whether actively or passively vented or both especially in the case of deep sites) | |
