Pigments add shine and colour to a multitude of daily products. They are ubiquitous in cosmetics, fashion, packaging, paints, and even food. However, as currently formulated, they contain a mix of problematic materials such as microplastics, mineral oxides, like titania and mica, and high GHG refined metals. Extractive mining is a major environmental and social concern for which there are currently very limited technological alternatives that would offer **plant-based, renewable and high performance metallic-effect colourants**.Without **a fundamental design and innovation shift in pigment technology**, direct pollution to the natural environment and GHG emissions from existing processes and supply chains enabled by petroleum consumption and extractive mining will never be eliminated. It is now clear that pigment materials have a negative impact on the environment across their entire life cycle and are not sustainable. They are associated with negative human health effects, are accumulating in the environment and have the potential to be toxic to animal and plant life. Therefore, there is an unmet need to develop truly sustainable alternatives.The solution is now available: the project partners Sparxell (SX) and Impossible Materials (IM) are start-ups aimed at the commercial delivery of **breakthrough sustainable pigments based on plants**: Sparxell has developed unique new pigments using cellulose-derived nanocrystals to deliver metal-like effects without metal; Impossible Materials' first product is a cellulose-derived white pigment, addressing one of the most environmentally problematic and high-volume pigments - titanium dioxide.In this collaboration, we will build a **new manufacturing process platform** by transforming the primary waste cellulose stream from the production of white pigments (IM) into functional cellulose nanomaterials that are the main and sole ingredient of metallic-effect pigments (SX).The overall process will be monitored and accompanied by a **cradle-to-cradle life cycle analysis (LCA)** performed by the Cambridge Institute for Sustainability Leadership (CISL), University of Cambridge. This rigorous approach will guide the process design and choice of materials to ensure that the overall production process is significantly more sustainable than the separate manufacturing processes used today by IM and SX.The overall aim of this project is to demonstrate the **technical viability, commercial attractiveness and sustainability benefits** of coupling Impossible Materials' nanocellulose waste stream to Sparxell's raw materials inputs to deliver a more profitable and sustainable supply chain for both organizations.

颜料为多种日常产品增添光泽和颜色。它们在化妆品，时尚，包装，油漆甚至食物上无处不在。但是，如目前所述，它们包含有问题的材料，例如微塑料，矿物氧化物，例如钛和云母，以及高温室气体精制的金属。提取挖掘是一个主要的环境和社会关注，目前有非常有限的技术替代方案将提供**基于植物的，可再生和高性能金属效应的颜色**。没有**颜料技术的基本设计和创新变化**，直接对自然环境的污染直接从现有过程和供应范围消除了彼得和供应范围，从而消除了彼得和供应范围的消耗，并提取了peterle的范围。现在很明显，色素材料对整个生命周期的环境产生负面影响，并且不可持续。它们与负面的人类健康效应相关，在环境中积累，并有可能对动物和植物生命有毒。因此，解决了真正可持续的替代方案的需求。现在可以使用该解决方案：Project Partners Sparxell（SX）和不可能的材料（IM）是旨在基于植物的**突破性可持续颜料的商业交付的初创企业**：Sparxell已使用纤维素衍生的Nananocrystals开发了独特的新色素，可提供金属型的Nananocrystals，没有金属型金属效果；不可能的材料的第一种产品是一种纤维素衍生的白色色素，它可以解决最有问题的和高体积的颜料之一 - 钛二氧化钛。在这种合作中，我们将通过将白色颜料的产生（IM）转化为功能性的纳米型含量的主要废料来构建一个**新的制造过程平台** （SX）。总体过程将受到剑桥大学可持续发展领导力研究所（CISL）的**摇篮到摇篮生命周期分析（LCA）**的监视和伴随。这种严格的方法将指导过程设计和材料的选择，以确保与当今IM和SX当今使用的单独的制造过程更可持续。该项目的总体目的是证明**技术的可行性，商业吸引力和可持续性效益**耦合不可能的材料材料的纳米纤维素浪费的纳米纤维质量流向Sparxell的供应材料，并提供更有价值的材料。
