DuPont Reduces Emissions and Fuel Usage through Sentinel Transportation
Sentinel Transportation, LLC, a joint venture of DuPont and ConocoPhillips, reduced NOx emissions by 4000 kg and CO2 emission by 3500 tons in 2007 thanks to state-of-the-art emission reduction and fuel saving programs.
Sentinel, which provides much of DuPont’s bulk truck transportation, has worked for the past several years to successfully implement multiple green initiatives which include limiting highway speeds to 60 mph, purchasing high efficiency truck engines, increasing payloads by reducing weight on trucks and trailers, using day cabs rather than sleeper cabs for one-day trips, specifying wide based tires on trucks and trailers and training drivers to maximize loads and optimize fuel efficiency. Over the next year, a new oil filtering system will be installed on all trucks to save DuPont over 2000 gallons of waste oil annually. Sentinel will generate an additional 5% increase in fuel efficiency and emission reductions with continual dual tire replacements on trucks and trailers.
Sentinel was able to cut fuel costs and emissions in half for a key DuPont automotive customer. Delivery schedules were modified by sending a single truckload for two days of operation instead of dispatching two partially loaded trucks on separate days. For another customer, heavy pumps and compressors were removed from the Sentinel trucks and unloading equipment was installed at the customer’s location. Delivery quantities per truck were increased while the number of loads was reduced by over 4%.
To support long standing environmental goals, DuPont continually focuses on emission reductions for outbound shipment to customers. At our Parlin, NJ site we increased the payload by 50% and reduced the number of trucks by 55% through freight optimization. These results were essentially replicated at our Towanda, PA, facility, where we increased the average weight per truck 51%, reduced the number of trucks by 45%, and consumed 31,000 fewer gallons of gas.
