The piece of work evaluates environmental impacts associated with the lab-scale production of 1 kg activated carbon (AC) as a functional unit from the obtainment of 2.14 kg feedstock. The environmental advantages over lignocellulose-based carbon, particularly in terms of acidification potential, non-renewable energy demand, and carbon footprint were considered. The quantification of environmental interactions over the stages of the life cycle of AC manufacturing chain, in terms of inputs of energy and natural resources and of outputs of emissions to the different environmental compartments, were studied. Drying (99.2%)and impregnation with an H2SO4(0.7%)attribute to major impact categories: carcinogens, respiration organics, respiration inorganics, climate change, radiation, the ozone layer, ecotoxicity, acidification, land use, minerals and fossil fuels. Disposal of AC might not affect the environment. On contrary, the predictions (human health(16.7%), ecosystem quality(0.928%), and resources(74.2%)) indicates that disposal of untreated brew waste might exhibit harmful effects to the environment hence improvements are necessary. In particular, the operations utilizing electricity, heat, natural gas and resources were the main factors causing emission to air, water and soil.

基于啤酒废料的碳生产的环境因素及其处置方案的评估

这项工作从获得2.14千克原料的角度评估了与实验室规模生产1千克活性炭(AC)作为功能单位有关的环境影响。考虑了基于木质纤维素的碳的环境优势,特别是在酸化潜力,不可再生能源需求和碳足迹方面。研究了交流制造链生命周期各阶段中环境相互作用的量化,包括能源和自然资源的投入以及向不同环境区域的排放的产出。干燥(99.2%)并用H 2 SO 4浸渍(0.7%)属于主要影响类别:致癌物,呼吸有机物,呼吸无机物,气候变化,辐射,臭氧层,生态毒性,酸化,土地利用,矿物质和化石燃料。处置AC可能不会影响环境。相反,预测(人类健康(16.7%),生态系统质量(0.928%)和资源(74.2%))表明,未经处理的啤酒废料的处置可能对环境产生有害影响,因此有必要进行改进。特别是,利用电力,热力,天然气和资源的作业是导致向空气,水和土壤排放的主要因素。
