项目摘要

This project brings together partners from glass (Glass Futures, Encirc, Calumite, Glass Technology Services, Diageo), steel (British Steel, the Materials Processing Institute, Tata Steel) and cement (LKAB Minerals, Hanson) sectors to develop a novel process to combine waste-materials into blast furnace slag to 'up-grade' low-quality materials into an enhanced Ground-Granulated Blast Furnace Slag (GGBS), increasing the volume of GGBS available for the cement and glass sectors, whilst creating a new value-added product enabling increased percentages to be used in glass-manufacturing.GGBS, sold into the glass sector as 'Calumite', is widely used in container-glass manufacture, displacing silica-sand and limestone, reducing process CO2 emissions, increasing melting rate and reducing furnace energy. Calumite also provides sulphides which refine the molten glass, increasing product quality.In the cement industry, GGBS partially substitutes Ordinary Portland Cement (OPC). OPC is made in a high-temperature, energy-intensive process from limestone and other raw materials, thus GGBS offers a significant reduction in energy and CO2 emissions.The project will utilise pilot scale equipment at Glass Futures and the Materials Processing Institute to develop and optimise this new technology, before undertaking a series of industrial-scale trials at British Steel and various glass manufacturing plants, including Encirc. Large-scale feasibility studies will also be undertaken by LKAB to assess the suitability of these new materials for use in cement applications.The project will engage the paper and ceramics sectors to identify waste-streams that could be utilised in the e-GGBS process and explore ceramics applications which might benefit from e-GGBS.

该项目汇集了来自玻璃的合作伙伴（Glass Futures，Encirc，Calumite，Glass Technology Services，Diageo），钢铁（英国钢铁公司、材料加工研究所、塔塔钢铁公司）和水泥（LKAB Minerals，Hanson）部门开发一种新工艺，将联合收割机废料结合到高炉矿渣中，以将低质量材料“升级”为增强的研磨粒化高炉矿渣（GGBS），增加了水泥和玻璃行业可用的矿渣微粉的数量，同时创造了一种新的增值产品，使玻璃制造业的使用比例增加。矿渣微粉，作为“钙铝石”出售给玻璃行业，广泛用于容器玻璃制造，取代硅砂和石灰石，减少工艺二氧化碳排放，提高熔化速度，降低炉能。在水泥工业中，矿渣微粉可部分替代普通波特兰水泥（OPC）。OPC是在高温、能源密集型工艺中从石灰石和其他原材料中生产的，因此GGBS可以显著减少能源和二氧化碳排放。该项目将利用玻璃期货和材料加工研究所的中试规模设备来开发和优化这项新技术，然后在英国钢铁公司和包括Encirc在内的各种玻璃制造厂进行一系列工业规模试验。LKAB还将进行大规模的可行性研究，以评估这些新材料在水泥应用中的适用性。该项目将与造纸和陶瓷行业合作，以确定可用于e-GGBS过程的废物流，并探索可能受益于e-GGBS的陶瓷应用。
