厌氧消化（AD）是一种从有机废物中提取能量的系统。该方法是有效的，因为所产生的能量是非化石相关的燃料，可以在源头消耗，从而减少在运输需求和直接能源使用中碳重化石燃料的使用。一旦能量从有机废物中被去除，残余物“亚硝酸盐”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，从而消除了人工化学增强我们的粮食生产土地的必要性，并节省了碳重化石燃料的生产和运输成本。通过投资于小型工艺效率，例如提高所有AD系统的沼气保留率，显著放大。在正确的地方投资5000英镑可以轻松节省50万英镑。

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.
