根据英国目前的脱碳政策，对玻璃工业实现净零的可能途径进行了总体展望，并指出了脱碳过程中的区别。生物质灰富含某些有利成分，主要是网络改性剂，被认为是制造低碳玻璃的潜在替代原料。结果表明，简单的筛分方法可以有效地从生物质灰分中分离出S、氯、碳等杂质。随着颗粒尺寸的增大，杂质的浓度降低。较大的洗涤生物质灰颗粒的形貌和X射线衍射图表明，在生物质燃烧过程中形成了液体/无定形相。对骨灰的清洗也被证明是一种潜在的净化途径。一种与现代和古代玻璃生产有关的洗涤蕨灰进行了表征，以进行比较。用生物质灰生产的代表性绿色容器玻璃的紫外可见近红外(UV-Vis-Near IR)吸收光谱证实，代表性批次的∼5%灰分对玻璃的颜色和氧化还原状态几乎没有影响；通过UV-Vis-近红外吸收光谱观察到，使用2 mm生物质灰生产的玻璃洗涤后的氧化还原状态比使用高水平(>；∼9 wt.%)的生物质灰单独筛分后的玻璃减少得少。
Based on the current UK decarbonization policy, a general outlook on potential routes for the glass industry to achieve net‐zero is discussed and the differentiation during decarbonization is specified. Biomass ash is considered a potential alternative raw material for low‐carbon glass manufacture as it is rich in certain advantageous components, chiefly network modifiers. Simple sieving processes were shown to effectively separate impurities such as S, Cl, and C from some biomass ashes according to particle size distribution. The concentration of undesirable impurities decreased with increasing particle size. Morphologies and X‐ray diffraction patterns of larger washed biomass ash particles indicated liquid/amorphous phase formation during biomass combustion. The washing of ashes was also shown to be a potential route to purification. A washed bracken ash relevant to both modern and ancient glass production was characterized for comparison. Ultraviolet‐visible near‐infrared (UV‐Vis‐near IR) absorption spectra of representative green container glasses produced using biomass ash confirmed that ∼5 wt.% ash in representative glass batches has little impact on the color and redox state of glasses; the redox status of glass produced using >2 mm biomass ash after washing was less reduced than that of glass produced using high levels (>∼9 wt.%) of >2 mm biomass ash after sieving alone, observed via the redox couple Cr3+/Cr6+by UV‐Vis‐near IR absorption spectroscopy.
