| Summary: | This paper compares the economic and environmental impacts of truck collection of household waste with those of the pneumatic tube system employed by one New York City neighborhood, Roosevelt Island (RI), since 1975. Although all homes are connected to the pneumatic system, businesses and institutions are not, meaning that trucks still collect three-quarters of the Island’s waste. In order to assess the potential benefits of employing pneumatic tube systems in other New York neighborhoods, the paper discusses the findings of a 2013 feasibility study which analyzed potential upgrades and extensions to the network. The study confirmed the context-specific nature of collection impacts and found that on Roosevelt Island trucks are more energy-efficient than the pneumatic system. However, the pneumatic scenarios tested would reduce truck miles by up to 70%, and could lead to a system based on 90% electricity While direct operating costs are slightly lower for the tube-based scenarios, when debt service on the initial capital expenditures is included, pneumatic systems are 40 to 90% more expensive. The study did not calculate the local impacts of increased heavy-truck traffic, but it suggests that the relative cost of pneumatic collection may be offset by the public benefit of reductions in these local impacts as well as improved collection of recyclable materials. Cet article compare les impacts économiques et environnementaux de la collecte des ordures ménagères (OM) par camion à ceux de la collecte pneumatique utiliséeée sur Roosevelt Island à New York City depuis 1975. Bien que toutes les habitations soient reliées au réseau pneumatique, les entreprises et les institutions ne le sont pas, en conséquence les trois quarts des OM de l’île sont toujours collectées par camion. Afin d’évaluer les avantages potentiels de l’emploi de systèmes pneumatiques, cet article examine les résultats d’une étude de faisabilité de 2013 qui a analysé des améliorations et extensions potentielles du réseau. L’étude a montré la nature ...
