The pneumatic nozzle uses a pressurized gas stream to push materials through the nozzle. Hera, Kevin R.Ī pneumatic nozzle capable of removing dry solid debris, liquids, and mixtures of solid and liquid waste is provided. Pneumatic conveyance apparatus and process If shown to be economically and : operationally feasible, reducing the num. This study explored possibilities for using existing transportation infrastructure for the cost-effective : installation of pneumatic waste-collection technology in Manhattan. All rights reserved.Ī study of the feasibility of pneumatic transport of municipal solid waste and recyclables in Manhattan using existing transportation infrastructure.ĭOT National Transportation Integrated Search While the electricity consumption of the hypothetical pneumatic system and the origin of electricity have a significant bearing on the results, emissions due to manufacturing the system's components prove decisive. Locally, in the waste collection area, emissions would nonetheless diminish, as collection traffic decreases. The results indicate that replacing the prevailing system with stationary pneumatic waste collection in an existing urban infrastructure would increase total air emissions. In this study, we report the atmospheric emissions of greenhouse gases (GHG), SO(2) and NO(x). The evaluation method used is the life-cycle inventory (LCI). Environmental loads are calculated for a hypothetical pneumatic waste collection system modelled on an existing dense urban area in Helsinki, Finland, and the results are compared to those of the prevailing, container-based, door-to-door waste collection system. Furthermore, we analyse whether the size of the hypothetical pneumatic system, or the number of waste fractions included, have an impact on the results. In this study, we compare the environmental sustainability of conventional door-to-door waste collection with its hypothetical pneumatic alternative. However, limited information is available on the environmental impacts of this system. Pneumatic waste collection systems represent a new way of arranging waste collection in densely populated urban areas. Waste collection is one of the life cycle phases that influence the environmental sustainability of waste management.
