Conversion of Paper Sludge to Ethanol and Potentially Recyclable Minerals

9613342 Lynd拟议的研究将解决废纸污泥转化为乙醇和可回收矿物的问题。由此产生的潜在效益包括：将重要的工业废物转化为有用的产品；提高纸张回收的成本效益和环境影响；提高乙醇生产和从纸污泥中回收矿物的成本效益，相对于单独进行这些努力中的任何一项；提高造纸污泥中矿物质回收再利用的技术可行性；为新兴的生物质乙醇工业提供切入点和试验场。研究建议建立在广泛的数据基础上，由P.I.组装的纸污泥组成和转化为乙醇。提出的任务将描述，改进和评估：-连续同步糖化和发酵（SSF）将预处理和未预处理的纸污泥转化为乙醇。——利用里氏木霉从纸污泥中生产纤维素酶，用于SSF系统。——利用嗜热细菌将纸污泥连续转化为乙醇。—液体热水（LHW）预处理作为一种手段，以增加纸张污泥向乙醇的高转化率和—根据评估其可回收性对矿物残留物进行测量。

9613342 Lynd The proposed research will address conversion of waste paper sludge to ethanol and recyclable minerals. Potential benefits derived include: diverting a significant industrial waste into a useful product; improving both the cost effectiveness and environmental impact of paper recycling; raising the cost-effectiveness of ethanol production and mineral recovery from paper sludge relative to either of these endeavors undertaken alone; improving the technical feasibility of recovering and reusing minerals from paper sludge; providing a entry point and proving ground for the emergent biomass ethanol industry. Research is proposed that builds upon an extensive data base on paper sludge composition and convertibility to ethanol assembled by the P.I. Proposed tasks will characterize, improve and evaluate: --continuous simultaneous saccharification and fermentation (SSF) for conversion of pretreated and non-pretreated paper sludges to ethanol. --use of Trichoderma reesei for the production of cellulase from paper-sludge for use in an SSF system. --use of thermophilic bacteria for continuous conversion of paper sludge to ethanol. --liquid hot water (LHW) pretreatment as a means to increase the fraction of paper sludges that exhibit high conversion to ethanol and --Perform measurements on mineral residues pursuant to evaluating their amenability to recycling.
