In the framework of the Europe 2020 Strategy for smart, sustainable and inclusive growth, Member States committed themselves to reducing GHG by 20% by 2020, raising this commitment in 2011 and targeting a reduction of GHG by 80-95% by 2050 (compared to 1990 level). The EU built environment is responsible for 40% of energy consumption and 36% of CO2 emissions.Miscanthus x Giganteus is a crop with a high yield (15 t/ha). It is a sustainable, fast growing, non-invasive, perennial energy crop. It can grow in degraded land and has phytostabilisation properties. It has a range of applications from land restoration to carbon sequestration, utilisation of fibres, energy production, and potential utilisation of ashes in a fully circular approach. Miscanthus fibres are a very promising source for developing novel, low cost, low carbon bio-based building materials with improved insulation properties, in line with the Clean Growth Grand Challenge and the GW4 community "Circular economy for affordable, low-carbon secondary raw materials" submitted to the Initiator Fund Round 10.The project aims at the development of building materials harvesting the full potential of miscanthus fibres. Although some applications have already been identified, the project will investigate the properties of each component of miscanthus product, listing possible end-products and prioritizing thosewith higher potential for commercial deployment in short to medium term. Building on available experience on "hempcrete", concrete-like materials will be developed investigating parameters such as fibre dimensions, binder content, curing conditions, and optimization of mix proportions. In order to improve the eco-profile of the product, binders different from Portland cement will be considered, such as lime and a new class of binders called geopolymers. Preliminary work carried out by CASE partners on the production of miscanthus fibreboards will be further developed and the potential of fibreboard alone and composite sandwich-like structures will be investigated. The project will determine production parameters and will assess technical properties of developed materials (e.g. achievable mechanical strength, thermal conductivity), along with preferred fields of application. In-depth LCA and and LCC analysis will allow to determine the eco-profile of the developed products and their appeal on the building material market, using existing off-shelf products as benchmark for targeted comparison.

在欧洲2020年智能、可持续和包容性增长战略的框架内，成员国承诺到2020年将温室气体减少20%，2011年提高了这一承诺，目标是到2050年将温室气体减少80-95%（与1990年水平相比）。欧盟建筑环境占能源消耗的40%和二氧化碳排放的36%。芒是一种高产作物（15吨/公顷）。它是一种可持续、快速生长、非侵入性、多年生的能源作物。它可以在退化的土地上生长，并具有植物稳定特性。它有一系列的应用，从土地恢复到碳封存，利用纤维，能源生产，以及以完全循环的方式利用灰烬。芒草纤维是开发新型、低成本、低碳生物基建筑材料的一个非常有前途的来源，具有更好的绝缘性能，符合清洁增长大挑战和GW 4社区提交给发起人基金第10轮的“经济实惠、低碳二次原材料的循环经济”。该项目旨在开发充分利用芒草纤维潜力的建筑材料。虽然已经确定了一些应用，但该项目将调查芒草产品的每种成分的特性，列出可能的最终产品，并优先考虑那些在中短期内具有更大商业部署潜力的产品。将根据“大麻混凝土”的现有经验，开发类似混凝土的材料，调查纤维尺寸、粘合剂含量、养护条件和混合比例的优化等参数。为了改善产品的生态特性，将考虑使用不同于波特兰水泥的粘合剂，如石灰和一类称为地质聚合物的新型粘合剂。CASE合作伙伴在芒草纤维板生产方面开展的初步工作将得到进一步发展，并将调查单独使用纤维板和类似复合纤维板结构的潜力。该项目将确定生产参数，并将评估开发材料的技术性能（例如可实现的机械强度，导热性），沿着首选应用领域。深入的LCA和LCC分析将允许确定开发产品的生态概况及其在建筑材料市场上的吸引力，使用现有的现成产品作为有针对性的比较基准。
