Version française disponibleSoil erosion on slopes is a natural phenomenon caused by the rainwater draining down the slope. Covering theslope with a protective layer of vegetation can stop loosening soil particles due to rain and preventing themfrom being washed down the slope. Erosion Control Blanket (ECBVerdyol) is a full line manufacturer oferosion control products, hydraulic mulches, and revegetation products. The company seeks to enter a newbusiness that would supply a lignin-based binder system to supplement ECB's sprayable mulch products.ECBVerdyol does not have a binder system that is needed to keep the mulch systems in place, especially onsloped earth when exposed to rain to prevent erosion. To improve the internal bonding of mulch, bindingagents can be added. The best commercial product that is being used in mulches is based on expensivepetro-chemically derived components. Therefore, the objective of this proposal is to develop a binder systembased on bio-renewable components such as lignin and glycerol.It is proposed that low and high ash content lignin made by West Fraser in Hinton, AB and supplied byECBVerdyol will be used and mixed with a natural plasticizer (glycerol). Mixture of water, glycerol, and ligninwill be tested for viscosity and tackiness. Blends of the above mixture with mulch will be tested for staticfriction by measuring the angle of repose. The experimental results of the tested mixtures will be compared tomulches mixed with a commercial product containing FINN E-Tack as a reference. The results of theinvestigations will provide data for ECBVerdyol with regard to the lignin-plasticizer-mulch ratio and will allowthe company to replace petrochemical-based components such as FINN E-Tack with the environmentallyfriendly lignin-based binder. The experimental results obtained from this project will be essential to help thecompany to make a decision on an economical scale-up production of a high-tack binder for the mulch systemsbased on bio-renewable components.

Version française disponible坡面土壤侵蚀是雨水沿坡面下泄造成的一种自然现象。用植被保护层覆盖斜坡可以阻止土壤颗粒因雨水而松动，并防止它们被冲下斜坡。侵蚀控制毯（ECBVerdyol）是一家生产侵蚀控制产品、液压覆盖物和植被重建产品的全系列制造商。该公司寻求进入一个新的业务，将提供一个基于木质素的粘合剂系统，以补充ECB的可喷洒覆盖产品。ECBVerdyol没有一个粘合剂系统，需要保持覆盖系统的地方，特别是在倾斜的土地上，当暴露在雨水中，以防止侵蚀。为了提高地膜的内部粘结力，可以添加粘结剂。用于覆盖物的最佳商业产品是基于昂贵的石油化学衍生成分。因此，本提案的目的是开发一种基于生物可再生组分（如木质素和甘油）的粘合剂体系。建议使用由West Fraser（位于欣顿，AB）生产并由ECBVerdyol提供的低灰分和高灰分木质素，并将其与天然增塑剂（甘油）混合。将测试水、甘油和木质素的混合物的粘度和粘性。上述混合物与覆盖物的混合物将通过测量休止角来测试静摩擦。将测试混合物的实验结果与含有FINN E-Tack作为参考的商业产品混合的乳液进行比较。调查结果将为ECBVerdyol提供有关木质素-增塑剂-覆盖物比例的数据，并将使该公司能够用环保的木质素基粘合剂取代石油化工基成分，如FINN E-Tack。从这个项目中获得的实验结果将是必不可少的，以帮助thecompany作出决定的经济规模生产的高粘性粘合剂的覆盖系统的基础上，生物可再生的成分。
