The Use of Air Quality Models in the Assessment of Air Quality Impact from Concrete Batch Plants

摘要

Until now, several models were running, with a different kind of controls and production. In those models, the main findings are: 1. Vehicular traffic is an important source into the plant. Attention of care of road and transit areas must be an activity of interest. The field observations and operator reports shows that a constant maintenance of the road surface and optimize the circulation cycle can give a guaranty of less PM concentration due emission of traffic. Paved surface, can reward investment in low maintenance costs and ease of cleaning to reduce particulate emissions. This is the case of Puente Aranda Plant, where a constant cleaning of road surface, and short travel into the plant, result in a low concentrations of PM, like models show, comparing with his big production. 2. Location of concrete batch plant, no matter its scale, must consider local conditions of air quality. Strategy location in a development area can give advantage in logistic term, but those areas are commonly affected by several sources of PM. Optimization of internal process, reducing the cycle of raw material and traffic for delivery the concrete help to significant reduce of PM emission.
