Americans throw away over 250 million tons of garbage every year. Out of all that garbage, approximately 32 percent is recovered and recycled or composted, 14 percent is burned at combustion facilities, and the remaining 54 percent (or 135 million tons of garbage) is disposed of in landfills. Because of limited disposal options, many municipalities are forced to transport garbage from local transfer stations to available landfills over long distances as well as pay increasingly higher tipping fees for landfill operators to take their garbage. Landfill operators dispose of garbage by burying it under mounds of dirt where, over time, toxins in the garbage can leach into our water supplies, or by burning it in incinerators releasing many of the toxic materials in the garbage into the atmosphere. We have licensed and developed a group of technologies that used together can process municipal garbage into usable energy products. We use the cellulosic material in municipal garbage to make ethanol by first converting it into a sugar and water mixture. Our ethanol production technology uses a two-stage dilute acid hydrolysis process that recycles heat and acid from each stage of the process to efficiently make C5 and C6 sugars from cellulosic material. The resulting sugars are fermented and distilled into a fuel grade ethanol.
