Performance BioFilament Inc. (PBI) is actively engaged in developing industrial applications of nanocellulose**filaments, a renewable resource product derived from wood fibre. The nanocellulose filaments have**exceptional strength and unique physical properties. These features permit the cellulose to be used as**reinforcement agents to enhance the strength and stability of a variety of materials. The company intends to**extend the application of their product to treat oil sands tailings. The oil sands mining industry in northern**Alberta has amassed a significant volume of over 1 billion cubic meters of fine grained slurry waste known as**fluid fine tailings (FFT). The FFT has poor settling properties and without treatment, the FFT would take**decades to settle and develop strength thereby delaying reclamation activities. To permit reclamation and**closure to proceed at the oil sand mine sites, the strength and density of FFT must be increased. Research is**needed to supplement current treatment approaches to stabilize the FFT and speed up the reclamation process.**It is anticipated that treatment of FFT with PBI's nanocellulose filaments would lead to a favourable increase in**strength and density. Through a series of bench top tests, measurements of potential strength and density**enhancements, as a result of treating FFT with nanocellulose filaments, will be conducted. Development of an**optimal dose and application method of the nanocellulose will also be undertaken. Ultimately, this project**aims to develop the process of using nanocellulose filaments to stabilize FFT thereby promoting faster**reclamation and closure of the oil sand tailings deposits.

Performance Biofilement Inc.（PBI）积极参与开发纳米纤维素**细丝的工业应用，这是一种源自木纤维的可再生资源产品。纳米纤维素丝具有**出色的强度和独特的物理特性。这些特征允许将纤维素用作**增强剂，以增强各种材料的强度和稳定性。该公司打算**扩展其产品的应用来处理油砂尾矿。北部**艾伯塔省的油砂矿业行业已经积累了超过10亿立方米的细粒泥浆废物，称为**流体细尾矿（FFT）。 FFT的定居特性差，没有治疗，FFT将需要数十年的时间来定居和发展力量，从而延迟开垦活动。为了允许填海和**在油砂矿场上进行，必须提高FFT的强度和密度。需要研究来补充当前的治疗方法来稳定FFT并加快填海过程。通过一系列的基准测试，将对用纳米纤维素丝处理FFT进行潜在强度和密度**增强的测量。还将开发**最佳剂量和纳米纤维素的应用方法。最终，该项目**旨在开发使用纳米纤维素丝稳定FFT的过程，从而促进更快的填海和封闭油砂尾矿沉积物。
