Each day millions of tons of plastic and organic products are "thrown away". Where is "away"? Probably a land fill. A better idea would be to somehow recycle these materials into a useful product, or use it as a source of energy.
A new patent application claims that a blend of waste plastic and cellulose from plant material can make a good building material or the plastic/cellulose mix could be burned for fuel. (click to view patent application, 38pg PDF)
It would be beneficial to develop a process that can efficiently and cost effectively convert multiple types of waste byproducts into useful materials usable for: (i) heat and/or energy generation; and/or (ii) structural, sound attenuation, and/or insulation materials.
Would someone explain what this patent does? To me it claims to own the concept of turning garbage into stuff or burning it. If someone works out detailed methods of doing what is described in the blockquote above, would they have to pay money to the person who patented the concept?
