A comprehensive life-cycle inventory of all consumptions and emissions of environmental relevance was made for the windrow composting plant treating garden waste in Aarhus (Denmark). The flows of materials and substances within the facility were balanced using the mass-balance model STAN. The overall fuel and electricity use at the facility (3.04 L diesel Mg(-1) wet waste (ww) and 0.2 k Wh Mg(-1) ww) was low whereas the emissions of CH( 4) and N(2)O from the windrows (2.4 ± 0.5 kg CH( 4)-C Mg(-1) ww and 0.06 ± 0.03 kg N(2)O-N Mg(-1) ww) were relatively high compared to data reported in similar studies. The loss of carbon during the 14-month-long composting was 56%. CH(4) made up 2.1% of the C lost. Loss of nitrogen-containing compounds was identified as the most sensible and uncertain parameter and could be relevant for global warming (N(2)O emissions), acidification (NH(3) emissions), and eutrophication (NH(3) and NO(3) emissions). The compost produced had a very low content of heavy metals and was suitable for use in gardens and/or agriculture.
对丹麦奥胡斯处理园林废物的条垛堆肥厂进行了全面的生命周期清单编制，以评估其所有与环境相关的消耗和排放。利用质量平衡模型 STAN 对设施内的物质流进行了平衡。该设施的总体燃料和电力使用量（3.04 升柴油 Mg(-1)湿废物（ww）和 0.2 千瓦时 Mg(-1) ww）较低，而条垛中 CH(4) 和 N(2)O 的排放（2.4 ± 0.5 千克 CH(4)-C Mg(-1) ww 和 0.06 ± 0.03 千克 N(2)O-N Mg(-1) ww）相对较高，与类似研究报告的数据相比。在 14 个月的堆肥过程中，碳损失了 56%。CH(4) 占损失 C 的 2.1%。含氮化合物的损失被确定为最敏感和不确定的参数，可能对全球变暖（N(2)O 排放）、酸化（NH(3) 排放）和富营养化（NH(3) 和 NO(3) 排放）产生影响。所生产的堆肥重金属含量非常低，适合用于花园和/或农业。
