    Pneumatic waste collection is a novel waste collection method. Its potential to increase safety and hygienic levels and reduce traffic flow makes the pneumatic waste collection an interesting choice when planning new solutions for the waste collection in dense urban areas. In this case study, the environmental loads (GHG, NOx and SOx) of hypothetical pneumatic system installed in Punavuori area, Helsinki, Finland, are calculated and the results are compared to those of the prevailing conventional vehicle operated waste collection system. Life cycle inventory (LCI) is used as a tool to evaluate the environmental loads of the relevant life cycle phases. A marginal analysis is performed by determining the environmental loads of the pneumatic waste collection first for a smaller area and then gradually expanding the analysis to cover a larger area. Also, the number of waste fractions collected varies in the different stages of the analysis. In the results, the loads formed in the whole case area in both waste collection systems are combined. According to the analysis, replacing the prevailing waste collection with pneumatic system would generate more air emissions. The electricity consumption and the origin of energy have a significant effect on the results, but decisive are the emissions from manufacturing the system components. On the local level emissions nonetheless diminish, since collection traffic reduces
