SOY OIL DERIVATIVESSoy-based methyl soyate and new soy solvents for stickies removal and cleaning and degreasingpaper machine equipment to replace chlorinated and petroleum solvents.• USB #2412 - Soy Methyl Esters Used in Recycled Paper Pulp Cleaning Systems, CescoSolutions, Inc. Cesco developed Purrge 200 to remove stickies and Purrge 100 fordeinking. Purrge 200 is being marketed in Latin America, China and the Middle East.Soy oil waxes can provide non-stick and barrier properties for packaging of aqueous products.Transfer of UV curing resin technology based on chemically modified soybean oil for woodfinishes to paper processing. At present these new soy coatings are unpigmented. It is probablethat these clear soy resins could be pigmented and used for UV cured colored paper coatings.United Soybean Board funded work at Lehigh and Northampton Community College.ENVIRONMENTAL AND REGULATORYThe United States Environmental Protection Agency (EPA) issued national regulations that setpollution prevention standards for the pulp and paper mills in the 1990s. These “Cluster Rules"link two major sets of standards for air and water which restrict pollution by industries thathave high effluent/emission volumes. These rules have significantly changed the way pulp canbe treated. The Clean Air Act in 1997 mandated chlorine restrictions in bleaching and chemicalpulping mills. Elemental chlorine use has been banned and the industry has switched toalternate bleaching and pulping processes involving chlorine dioxide. Maximum AchievableControl Technology (MACT), which limits air discharge of vented gas, has caused conversion tooxygen delignification processes.Water recycling expectations of mills have emphasized two potential methods. ZEF (ZeroEffluent Mill) is a closed loop water system where a complete balance exists between input andoutput - all water is recycled, reused and cleaned. In contrast, the TEF mills (Total Effect Free)produce effluent, but the wastewater has been treated to meet water pollution standardswithout the large expenditure required for ZEF.The 2008 proposed ban on perfluorooctanoic acid (PFOA - Teflon) has prompted research intoalternative materials to impart grease and oil resistance to paper and packaging applicationsuch as pizza boxes, disposable food containers and pet foods bags. Ashland has beensuccessful in marketing alternatives with no detectable PFOA.33
Agenda 2020 created in 1994 as a partnership between the American Forest and PaperAssociation and the Department of Energy’s Industrial Technologies Program (ITP) has theobjective of accelerating the research and development of new technologies in the paperindustry. Emphasis is on developing processes and technologies that can cut energy use,minimize environmental impacts and improve productivity in industry. Bio-based alternativetechnologies are sought for evaluation.UNMET NEEDS• Innovative and sustainable alternatives with stable pricing over the long term. Thecommodity nature of paper markets demands high quality at very slim profit margins.The volatility of petrochemical pricing puts a great risk on profitability from day to day inan industry that requires huge capital investment to maintain and advance pulp andpaper processing.• Alternative sources of cellulose are needed as wood resources become scarce andcostly. The high alpha cellulose content of soy hulls makes an ideal starting material fordissolving pulp. Demand growth is forecasted to continue between 3-7% per year. L• Dry strength and dimensional stability additive improvements from cost saving measuressuch as increasing recycled fiber content and/or thinner base sheet. Stronger resins withenhanced binding abilities in wet-end or coating applications can compensate forstrength reduction with recycled fibers.• Optimization of water resources using effective drainage and retention aids.• Optimize wet-end components to maximize fiber retention and water removal ahead ofdry end for more efficient drying. Existing petro chemicals such as polyacrylamides andpolyampholytes are costly.• Increased deinking mill production capacity. Demand for recycled paper fiber is growingbut industry deinking mill production is not keeping pace. The use of recycle pulp varieswidely from 45% in tissue products to only 6% in printing and writing papers. There are17 major deinking mills in the United States that are running at 90% of capacitycurrently in the face of this rising demand. Additional capacity and better quality fiberproduction is required to supply recovered paper pulp to more finished paper gradesthat could use it. This will require the utilization of more effective chemicals to deinkand remove stickies from recycled fiber.• More effective stickies removal processes. Recycle fiber is being recovered at a rate of44 million tons annually in the United States. Currently, 75% of paper mills utilizerecovered fiber and 200 mills are 100% recycle. It is estimated that the economicimpact of stickies on paper industry production is $700-800 million per year. The cost34
