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 BioFilament Inc (PBI)积极开发纳米纤维素 ** 长丝的工业应用，纳米纤维素 ** 长丝是从木纤维中提取的可再生资源产品。纳米纤维素长丝具有 ** 卓越的强度和独特的物理性能。这些特性使纤维素可用作增强剂，以增强各种材料的强度和稳定性。该公司打算扩大其产品的应用范围，以处理油砂尾矿。北方 ** 阿尔伯塔的油砂开采业已经积累了大量超过10亿立方米的细粒泥浆废物，称为 ** 流体细粒尾矿（FFT）。FFT具有较差的沉降特性，如果不进行处理，FFT将需要数十年的时间来沉降和形成强度，从而延迟填海活动。为了允许在油砂矿场地进行复垦和关闭，必须增加FFT的强度和密度。** 需要进行研究，以补充目前的处理方法，稳定快速傅立叶变换，并加快回收过程。预期用PBI的纳米纤维素长丝处理FFT将导致 ** 强度和密度的有利增加。通过一系列的实验室试验，将进行作为用纳米纤维素长丝处理FFT的结果的潜在强度和密度 ** 增强的测量。还将开发纳米纤维素的最佳剂量和应用方法。最终，该项目 ** 旨在开发使用纳米纤维素长丝稳定FFT的工艺，从而促进油砂尾矿沉积物的更快 ** 回收和关闭。
