Abstract
A biofuel that includes a blend of municipal solid waste, selected recyclables, and/or construction and demolition waste including about 40% to 60% wood, about 10% to 20% paper, about 10% to 20% cardboard, about 5% to 10% non-chlorinated plastics, about 5% to 10% rags, about 5% to 10% rugs, and an emission reducing agent, the emission reducing agent being one or more of urea, calcium hydroxide, hydroquinone, anthraquinone, ammonium hydroxide, ammonia, and an ammonium compound.
Claims10
A composition of matter comprising a blend of:
- between about 40% to 60% wood;
- between about 10% to 20% paper;
- between about 10% to 20% cardboard;
- between about 5% to 10% non-chlorinated plastics;
- between about 5% to 10% rags;
- between about 5% to 10% rugs;
- and
- an emission reducing agent, the emission reducing agent being one or more of urea, calcium hydroxide, hydroquinone, anthraquinone, ammonium hydroxide, ammonia, and an ammonium compound,
- wherein the urea reduces nitrous oxide emissions, the calcium hydroxide reduces carbon dioxide emissions, the hydroquinone reduces sulfur emissions, the anthraquinone reduces sulfur emissions, the ammonium hydroxide reduces carbon dioxide emissions, and the ammonia and ammonium compound reduce carbon dioxide emissions, when the composition is combusted.
