Abstract
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
