Why Anaerobic Digestion?
Fairfield AD Ltd. has experience of composting fruit and vegetable waste through Fairfield Materials Management, which produces beautiful, PAS 100 compost. This system works because it's in-situ and diverts a pure food waste from landfill for composting.
We do not believe that co-mingled collections of household food and green waste for in-vessel composting provide the best environmental nor economic solution for a Local Authority.
Recent reports for Defra suggest that pure food waste collections with AD processing are not cost inhibitive and offer the best environmental solution of all systems examined within the research(1). A 2006 report (2) from the US stated that 'one of the main disadvantages of just composting is the associated odours (which can create problems at the planning stage). The fats and oils that generate these odours are actually ideal for the production of energy . . . In the not too distant future, composting facilities (and biogas facilities) will all contain a mixture of recovery technologies sharing much of the same equipment’.
The Defra report concluded that no country is currently collecting and processing 100 per cent food waste, stating that this is 'a genuine opportunity for the UK to take a lead in the management of biowaste and to use its late-mover advantage to leap-frog over the erstwhile ‘leading nations’ in managing biowaste more sustainably'.
The Fairfield solution has been created to maximise the potential of materials to create a new approach to waste management. It utilises the US vision, with additions, to create a unique model for waste processing in Europe.
