厌氧消化(AD)是一种从有机废物中提取能量的系统。这一过程是有效的，因为所生产的能源是一种与化石无关的燃料，可以从源头上消费，从而减少了运输需求和直接能源使用中重碳化石燃料的使用。一旦从有机废物中去除能源，残渣是一种高价值的有机肥料，可以完全取代对化学肥料的需求，从而消除人为地提高粮食生产用地的必要性，并节省重碳化石燃料生产和运输成本。通过投资于小的过程效率，如提高所有AD系统的沼气保留率，好处可以显著放大。在正确的地方投资5000 GB可以很容易地节省500,000 GB。

Anaerobic Digestion (AD) is a system for extracting energy from organic waste. The process is efficient in that the energy produced is a non-fossil related fuel that can be consumed at source thereby reducing the use of carbon heavy fossil fuels in both the transportation requirement and direct energy use. Once the energy has been removed from the organic waste the residue ‘digestate’ is a high value organic fertiliser that can replace entirely the need for chemical fertilisers thereby eliminating the necessity to artificially chemically enhance our food producing land and saving on carbon heavy fossil fuel production and transportation costs.By investing in small process efficiencies such as improving the biogas retention of all AD systems the benefits can magnified significantly. £5000 invested in the right place can easily result in a £500,000 saving.
