Silicone manufacturer Dow Corning said it made significant progress in reducing their waste partly through its materials conversion program, which converts or recycles its waste, scrap and off-spec silicone materials instead of sending them to landfill or incineration. Materials are then reprocessed into new products that meet customers’ specifications.
In Europe, the company said it was able to reduce 80% of its waste in Seneffe, Belgium plant, and 10% in its Barry, Wales site. The Barry plant was also able to use a recycled solvent which reduced the plant’s overall amount of waste solvent.
In North America, Dow Corning said it was able to reduce consumption of natural gas and carbon dioxide emissions by burning hydrogen at its Midland, Michigan plant; reduced the amount of solvent used in a coating process in Midland using recycled solvents; and reduced emissions of greenhouse gases through energy reduction at its Carrollton, Kentucky plant.
In China, the company was able to recycle more than 80 percent of the waste at its Zhangjiagang (ZJG) sealant plant as well as reduced generation of nonhazardous silicone and solvent streams in the plant by 50% through the first half of 2008.
