Fig. 5: The influence of digestate transportation distance on the amount of favorable land for siting anaerobic digesters.
From: Integrating regional transportation and ecological factors into anaerobic digestion siting decisions
The percent of available land with favorable conditions for siting an anaerobic digester in Western New York as a function of the distance over which digestate must be transported to nearby fields for land application. Here, favorable land reflects places where an anaerobic digester could be sited and not lead to more phosphorus application than fields within this transportation radius could accept. This graph reflects two scenarios: one in which digestate is generated from wasted food (WF) and manure co-digestion (blue line) and one in which lower volumes of digestate are generated from the digestion of wasted food alone (orange line).
