Althoughcement is a strong construction material, its manufacture produces the same weightof CO2 as it does cement (this was 5 billion tonnes last year). An alternative eco-friendlysetting agent can be produced from sodium and aluminium silicates, that combine to form ageopolymer – a glassy rock-like material that can be made harder and more durable thanconcrete.We have identified an opportunity to produce geopolymer material in an exceptionally eco-friendly way by utilising waste streams from another recycling process – one developed byour sister company to remove toxic lead from CRT glass screens. Once the lead is removedand prepared for sale, they have a clean output stream of mixed silicates. Our project is todevelop the method to prepare this silicate material into the form that it can be used to form ageopolymer.This geopolymer is intended to be stronger, denser, more resistant to chemical attack andmore waterproof than concrete. We plan to develop it for use in our 1-tonne ‘Lego’ styleinterlocking blocks.These blocks provide an easy to install, flexible and re-usable construction system withunparalleled protection from impact, blast and water. It is suitable for temporary, emergencyor permanent construction. It is a flexible & low cost construction system that is easy to use,quick & simple to build, dismantle & re-locate. Due to its unique interlocking design it can bedry laid, or it can be laid with mortar for a permanent solution. No maintenance is required.Two men can dry lay a 50-metre long 1.2m high wall in just 1 hour. It can be used for a widevariety of applications such as;•Flood Defence - permanent or mobile as part of Environment Agency’s strategy•Land Defence - landslide protection & erosion control (permanent or mobile)•Security & Construction - walls, compounds, barriers•Transport - road & culvert repairs, railway embankments, barriers•Bulk Storage & Segregation – construction; agriculture; recycling

尽管水泥是一种坚固的建筑材料，但其制造过程产生的二氧化碳与水泥相同(去年为50亿吨)。一种替代的环保固化剂可以从硅酸钠和铝硅酸盐中生产出来，这两种物质结合在一起就形成了一种像玻璃一样的岩石材料，可以变得比混凝土更坚硬和更耐用。我们已经找到了一个机会，通过利用另一种回收工艺的废液--你的姐妹公司开发的一种去除CRT玻璃屏幕上的有毒铅的方法--以一种特别环保的方式生产地质聚合物材料。一旦铅被去除并准备出售，它们就有了干净的混合硅酸盐输出流。我们的项目是开发一种方法，将这种硅酸盐材料制备成可用于形成聚合物的形式。这种地质聚合物的目的是比混凝土更坚固、更致密、更耐化学侵蚀和更防水。我们计划将其开发用于我们1吨的‘乐高’风格的联锁积木。这些积木提供了一个易于安装、灵活和可重复使用的建筑系统，具有无与伦比的防冲击、防爆炸和防水保护。适用于临时、紧急或永久施工。它是一种灵活、低成本的施工系统，使用方便，建造、拆卸和重新定位快捷简单。由于其独特的联锁设计，它可以铺设床铺，也可以用砂浆铺设永久解决方案。不需要维护。两个人可以在短短一个小时内干铺一堵50米长1.2米高的墙。它可用于多种应用，例如：·防洪--作为环境署战略的一部分，永久性或移动性·土地防御--滑坡保护和侵蚀控制(永久性或移动性)·安全与建筑--墙、院落、障碍物·运输-道路和涵洞维修、铁路路堤、障碍物·散装储存和隔离--建筑；农业；回收
