Zero Waste Semiconductor Facility

A process designed to achieve zero waste from a semiconductor facility has been completed. Moving towards zero waste by means of high temperature and burning in the presence of excess oxygen with potent scrubber towers to obtain Btu value. CO2 released from the high temperature burning is fed to algae for the production of ethanol. Additionally, a reverse osmosis facility is installed to aid the incinerating plant in its need for water. Research was conducted to evaluate the feasibility of producing methane gas from combined solid/food and agricultural waste. The agricultural waste was feedlot manure acting as a catalyst for the reaction. The results showed that the combined waste can produce as high as 1.82 m3 of CH4 per day. The process of recycling the chemical waste was done by diffusion dialysis. The proposed design accounts for solid as well as chemical waste with a 94% recovery of all material discarded from the facility.
