I don't think they are including plastic in their "organic waste" stream.

They obviously are not. From Harvest Power's website (emphasis added by me):

We design and build two types of anaerobic digestion systems to meet the organic waset, environmental and economic needs of each site:

Low solids anaerobic digestion - best for pumpable slurries like manure, wastewater and pulped food waste that are less than 20% solids content. Materials are blended, mixed with heated water and innoculum to kick-start the digestion process, and pumped into the chamber(s) where digestion and biogas production occur. After digestion the solids are separated from the liquids and either composted or pelletized for land application. The liquids are processed through a wastewater treatment system. Many low solids anaerobic digestion facilities are successfully operating around the world, commonly at municipal wastewater treatment plants and dairy farms.

High solids anaerogic digestion - also known as "dry fermentation", best for stackable materials like food waste and yard debris that have a solids content of 25% - 50%. Materials are mixed and loaded into digestion chambers using a wheel loader. After two weeks in the digestion system the partially degraded material is aerobically composted while the biogas can be used for power generation, heating or vehicle fuel.

Biomass Gasification

Harvest employs a revolutionary gasification technology to convert wood waste and other dry, lignitic feedstocks into renewable syngas ideal for producing electricity, heat and substitute natural gas.
