This classification can be further divided by the nature of the [[Food Waste]] (i.e. [[Animal By-product Material|ABPR]] and non-[[Animal By-product Material|ABPR]] material) - where the process utilises [[Animal By-product Material|ABPR]] materials, it must comply with the [[Animal By-Products (Enforcement) (England) Regulations 2011]] requirements and some Agricultural plants, for example, only utilise non-[[Animal By-product Material|ABPR]] material so as to avoid the need to comply with these requirements. Additionally, the three different feedstocks in the 'Agricultural' classification can be co-digested in different combinations to optimise plant productivity and yield of [[biogas]] and can be talked about in those terms.[[Sewage Sludge]] doesn't tend to be blended with other materials and tends to be a dedicated AD solution in its own right - primarily as it becomes impossible to to deliver [[End of Waste Criteria|End of Waste]] [[digestate]] with the introduction of [[Sewage Sludge]] as an input feedstock. | This classification can be further divided by the nature of the [[Food Waste]] (i.e. [[Animal By-product Material|ABPR]] and non-[[Animal By-product Material|ABPR]] material) - where the process utilises [[Animal By-product Material|ABPR]] materials, it must comply with the [[Animal By-Products (Enforcement) (England) Regulations 2011]] requirements and some Agricultural plants, for example, only utilise non-[[Animal By-product Material|ABPR]] material so as to avoid the need to comply with these requirements.

The online tool captures those plants which are based on four different feedstock configurations and three different power output configurations. A summary of the total plants listed is set out below, with an extract in the map to the right of MSW/Commercial [[Food Waste]] AD facilities generating electricity: | ||
