I didn't know where else to post this... I detest the plastic part but at least they are looking at ways to use manure unfit for gardening.
Quoting:
Construction Materials Developed From Manure Products
A Michigan State University Extension educator has developed a way to turn manure into environmentally friendly construction materials. An anaerobic digester was used to break down manure solids into a fibrous material; the digester fiber was then combined with plastic to create a digester fiber/plastic composite product that can be used as decking and medium-density fiberboard. When tested, the fiber/plastic composite met or exceeded industry standards and even performed better than some wood/plastic composite products. The development of the fiber/plastic “lumber” was supported by a grant from the Michigan Biomass Energy Program.
