incorporated into our current Dulles International Master Planning process and eventually the planning process for Reagan National as well .
Salt Use Along the Dulles Toll Road
While rock salt is an effective means to protect drivers along the DTR from icy and snowy conditions , this salt eventually makes its way into surrounding waterways with negative environmental repercussions . The quantity of salt we need to use is dependent on weather conditions . Nonetheless , there are potential replacements for rock salt that have fewer impacts on the environment but are still effective . In addition , we may be able to improve our process for applying rock salt to the roads , so that the total quantity needed is reduced . One area that could be explored is utilization of pavement monitoring systems to evaluate the current and potential temperature of the roadway system based on weather forecast , chemical composition sensors , and pavement temperature sensors . These systems can enable operators to forecast the need to apply the appropriate chemicals prior to impending weather events , and monitor areas that may need reapplication . The result is more targeted application of safety products , with less waste and environmental impacts .
Summary
With over 16,000 tons of municipal solid waste generated each year across our airports and other facilities , there are many opportunities to reduce this amount and save money in the process . Rethinking the process by which goods enter our airports for subsequent distribution to concessionaires may create opportunities for waste reduction . Our rates of recycling are relatively low , and contamination of recyclable materials also appears to be an issue . Despite the higher costs , we will continually look for ways to improve on both metrics . Nonetheless , we are fortunate that what we do not recycle is sent to a WtE facility as raw material to produce electricity . As a result , the percentage of our waste that is disposed of at the landfill is low compared to our peers . Finally , improving on our waste stream management practices is also a team effort and we look forward to working with our various partners in this area .
