Enhanced Ground Granulated Blast Furnace Slag for use in glass and cement sectors (e-GGBS)

这个项目汇集了来自玻璃(Glass Futures，EnCirc，Calumite，Glass Technology Services，Diageo)，钢铁(British Steel，The Material Procedure Institute，Tata Steel)和水泥(LKAB Minerals，Hanson)部门的合作伙伴，开发一种新的工艺，将废物结合到高炉炉渣中，将低质量材料提纯到强化磨细高炉炉渣(GBS)中，增加水泥和玻璃行业可用的GBS数量，同时创造一种新的附加值产品，使更多的百分比能够用于玻璃制造。GBS，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，降低窑炉能耗。方解石还提供硫化物来精炼熔融的玻璃，提高产品质量。在水泥行业，GGBS部分取代了普通波特兰水泥(OPC)。OPC是由石灰石和其他原材料通过高温、能源密集型工艺制造的，因此GGBS显著减少了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在内的多家玻璃制造厂进行一系列工业规模的试验。此外，LKAB亦会进行大规模的可行性研究，以评估这些新材料是否适合用作水泥用途。这项计划会与造纸业和陶瓷业合作，找出可用于e-GGBS工序的废流，并探讨可从e-GGBS中获益的陶瓷应用。

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.
