SOY CHEMICALS FOR PAPER PROCESSING - Soy New Uses

Energy consumption can be reduced by up to 65% by using recycled pulp according to theBureau of International Recycling. Water use by the paper industry is vast but can be reducedby about 50% using recovered paper and by closed-loop recirculation of wastewater. Producingpaper from recycled pulp is generally a cleaner manufacturing process which reduces chemicaluse and cuts the generation of waste. Copy paper made from 100% recycled paper fiber, versus100% virgin wood fiber, reduces wastewater and solid waste by 50% and particulate emissionsby 41%. The recycling of waste paper also saves landfill space and reduces greenhouse gas(methane) emissions from land filled paper by about 38%.Sources of Recycled StockThere are three categories of paper waste that are recycled to produce “recovered” paper:• Mill broke is paper trimmings and other scrap from the manufacture of paper that isrecycled internally in a paper mill.• Pre-consumer waste includes scraps created in a paper mill after the initialpapermaking process as well as scraps from paper converters and printers.• Post-consumer waste includes old corrugated cartons (OCC), old newspapers (ONP)and office/residential mixed paper (RMP).Recycling ProcessRecycling starts with the sorting of waste paper by type: newsprint, magazines, etc. Each typeis processed differently as determined by waste (scrap) paper composition and the recoveredpaper product that will be produced.FIGURE 1223
