===Technical===
[[Biochemical oxygen demand]] (BOD) is a measure of the amount of oxygen required by aerobic micro-organisms to decompose the organic matter in a sample of material being used in the biodigester as well as the BOD for the liquid discharge allows for the calculation of the daily energy output from a biodigester.

Another term related to biodigesters is effluent dirtiness, which tells how much organic material there is per unit of biogas source. Typical units for this measure are in mg BOD/litre. As an example, effluent dirtiness can range between 800 and 1200&nbsp;mg BOD/litre in Panama.{{citation needed|date=February 2014}}

From 1&nbsp;kg of decommissioned kitchen bio-waste, 0.45&nbsp;m<sup>3</sup> of biogas can be obtained. The price for collecting biological waste from households is approximately €70 per ton.<ref>{{cite journal|last1=Obrecht|first1=Matevz|last2=Denac|first2=Matjaz|title=Biogas – a sustainable energy source: new measures and possibilities for SLovenia|journal=Journal of Energy Technology|date=2011|issue=5|pages=11–24|url=http://www.fe.um.si/images/jet/jet4-5-internet.pdf}}</ref>
