**Material Research Ltd** has developed a novel bio-based insulation material that utilises locally grown hemp as the insulating material, held together with a patent pending binder. This material, trade marked HempSil, has already been licensed for use as the moisture buffering insulation within a pre-fabricated construction solution comprising a breathable thermal envelope, cladding, internal walls, internal finishes and MEP services. The Natural Building System requires a breathable board to provide a fire resistant layer and to support the internal finishes and currently the only available materials are cement based woodwool materials which have relatively high embodied energy and are heavy and awkward to handle.This project is a feasibility study to create a replacement for imported woodwool boards which will make use of a waste stream from the production of biodiesel, combined with locally grown hemp.Hemp is an annual crop which bio-remediates contaminated soil, improves soil structure and nutrient levels and can lead to greater yields in follow-on crops. Most importantly hemp is a growing industry which empowers small communities by providing local manufacturing and industry employment.The combination of these two materials will result in a low density breathable acoustic and thermal insulation board with a very low environmental impact. A 25mm thick 2m x 600mm board will weigh around 6kg and would have a thermal conductivity of 60mW/mK.The proposal is to develop this material, using known technology, through to prototype full scale boards.Benefits from this novel board include:* Supply chain resilience with no reliance on imported raw materials or finished goods* Growth in local employment* Valorisation of an industrial waste-stream* Improved ease of use on site through lower unit weights* Improved thermal performance of buildings

** 材料研究有限公司 ** 开发了一种新型的生物基绝缘材料，利用当地种植的大麻作为绝缘材料，与正在申请专利的粘合剂结合在一起。这种材料，商标为HempSil，已经被许可用作预制建筑解决方案中的水分缓冲绝缘材料，该解决方案包括透气热外壳，覆层，内墙，内部饰面和MEP服务。天然建筑系统需要透气板来提供防火层并支撑内部饰面，目前唯一可用的材料是水泥基木丝材料，其具有相对高的内含能量，并且沉重且难以处理。该项目是一项可行性研究，旨在利用生物柴油生产中的废物流来替代进口木丝板，大麻是一种一年生作物，可对受污染的土壤进行生物修复，改善土壤结构和养分水平，并可提高后续作物的产量。最重要的是，大麻是一个不断发展的行业，通过提供当地制造业和工业就业机会来增强小社区的能力。这两种材料的结合将导致低密度透气隔音和隔热板，对环境的影响非常小。一个25 mm厚的2 m x 600 mm板将重约6 kg，导热系数为60 mW/mK。该提议是使用已知技术开发这种材料，直至原型全尺寸板。这种新型板的好处包括：* 供应链弹性，不依赖进口原材料或成品 * 本地就业增长 * 工业废物流的价值化 * 通过降低单位重量提高现场使用的便利性 * 提高建筑物的热性能
