Abstract:本文在啤酒酿造阶段基础上,将原料种植及麦芽制备引入研究范围,利用Gabi5.0软件对啤酒进行从摇篮到大门的生命周期评价.各阶段考虑温室效应、酸化、富营养化、非生物资源消耗、人体潜在毒性、光化学毒性6种环境影响类型.结果表明,温室效应是啤酒生产对环境影响的主要类型,占总环境影响潜值43.75%,环境影响由强至弱分别为温室效应、富营养化、酸化、人体潜在毒性、光化学毒性和非生物资源消耗.灌装阶段是造成环境影响的主要阶段,占总环境影响潜值39.77%,种植阶段次之.其中灌装阶段的温室效应、非生物资源消耗、人体潜在毒性和光化学毒性影响潜值为啤酒生产各阶段最高值,种植阶段的富营养化、酸化影响潜值在各阶段最高.对灌装阶段采用传输管道改进,空压机热能回收、蒸汽二次利用等清洁生产方案降低能源消耗和环境影响,方案实施后蒸气和电能消耗分别减少247.66 MJ和4.46 kWh,温室效应影响潜值减少19.18%,具有一定的环境效益和经济效益.
