We have invented a novel process for recovering commercially-valuable natural products from a pulp and paper (P&P) mill waste stream. Papermaking is a multi-step process utilizing large volumes of water, while generating considerable organic waste. One specific stream, black liquor condensate, is produced during the chemical and energy recovery step of the pulping process. Due to the organic compounds present, this stream is one of the most environmentally toxic in the mill, requiring considerable treatment. However, many of these compounds are very valuable when recovered. Our analysis of the natural product market has identified an immediate and considerable market for one specific compound, manool, which is used in proprietary processes by the flavour and fragrance industry. Together with two industrial partners (one pulp mill and one industrial processer) this current project will implement a pilot trial to achieve three objectives. Firstly, to test pilot scale production equipment and to create early production specifications for a commercial-scale process. Secondly, to produce sufficient samples of manool for prospective customer consideration and feedback. Thirdly, to de-risk the technology and develop a sustainable and profitable business plan. The first phase of the process, at the pulp mill, involves the crude recovery of the condensate, for shipping to the industrial processer. The processer will then implement the second phase of isolating and purifying the product for customers. For the P&P industry our invention provides a "bolt-on" solution, generating value-added products from waste streams, while addressing pressing environmental and economic issues. This also provides the Canadian chemical industry with new ways to generate revenue and to share them with P&P producers.

我们发明了一种从纸浆和造纸厂(P&P)废水中回收具有商业价值的天然产品的新工艺。造纸是一个多步骤的过程，利用大量的水，同时产生大量的有机废物。在制浆过程的化学和能量回收步骤中，会产生一种特殊的流--黑液冷凝液。由于存在有机化合物，这条溪流是工厂中环境毒性最大的溪流之一，需要大量处理。然而，这些化合物中的许多在回收时都非常有价值。我们对天然产品市场的分析发现，一种特殊的化合物甘露醇立即有相当大的市场，这种化合物用于香料和香料行业的专有工艺。目前的项目将与两个工业伙伴(一个纸浆厂和一个工业加工厂)一起进行试点试验，以实现三个目标。首先，测试中试规模的生产设备，并为商业规模的工艺制定早期生产规范。其次，提供足够的甘露醇样品，以供潜在客户考虑和反馈。第三，降低技术风险，制定可持续和有利可图的商业计划。该过程的第一阶段是在纸浆厂，涉及凝析油的原油回收，然后运往工业加工机。然后，加工者将为客户实施分离和提纯产品的第二阶段。对于P&P行业，我们的发明提供了一种“补充式”解决方案，从废流中产生增值产品，同时解决紧迫的环境和经济问题。这也为加拿大化学工业提供了产生收入并与P&P生产商分享收入的新方式。
