As the largest privately held LTL carrier in North America, Estes understands that our day-to-day actions have an impact on the world around us. That’s why we strive to reduce the emission of harmful pollutants and the consumption of natural resources by adhering to eco-friendly policies and processes throughout our company.
In addition to helping preserve the environment, many of our green initiatives also allow us to operate more efficiently and cost effectively. Every day, Estes proves that it’s possible to provide affordable, top-of-the-line freight transportation services while still being good stewards of the earth. Here’s how we do it:
The EPA has consistently awarded Estes the highest possible score among SmartWay partners for our environmental efforts. Estes also uses vendors that are EPA SmartWay partners for purchases of new tractors, trailers and tires.
From lightbulbs to scrap metal, Estes keeps waste out of landfills and conserves precious natural resources by reusing and recycling materials. Learn more.
Recycling efforts—We send all of our scrap metal to recyclers, which has kept thousands of tons out of landfills across the country. What’s more, we help protect the groundwater by having a licensed disposal company collect and recycle our used antifreeze, oil and oil filters in an environmentally responsible manner.
Improved shop cloths—We conserve water and electricity—and help keep detergents and other chemicals from the environment—by replacing washable cloth shop rags with biodegradable, paper-based clean-up sheets.
Paper conservation—Since 2006, we have reduced our company-wide paper consumption by millions of sheets through employee education and by providing customers with paperless e-commerce solutions (online shipping forms, EDI and Web Services, etc.).
Refurbished parts and components—We use rebuilt/remanufactured components when repairing units—including starters, alternators, brake shoes, transmissions, differentials and other parts. In 2014, Estes also plans to refurbish at least 200 trucks by installing new chassis.
LED lighting—All 2006 and newer equipment purchases are equipped with LED lighting. This long-life lighting technology will reduce the number of light bulbs we discard by an estimated 50%.
Repurposed materials—Our nationwide network of more than 200 terminals reuses cardboard and pallets as dunnage to help secure customer freight during transit.
Recapped tires—We have extended tread life and reduced waste by recapping more than 135,000 tires since 2008.
Estes follows environmentally responsible procedures to keep harmful pollutants out of the air and groundwater in the communities we serve. Learn more.
Nonhazardous cleaning solutions—Our shop facilities use a nonhazardous solution for parts cleaning to minimize waste disposal. And to help protect groundwater from contaminants, no chlorinated solvents are used in our shops.
Smarter wash systems—Many of our wash systems feature oil-water separators, plus closed-loop applications that minimize discharge to sewer systems. For facilities without wash systems, outside contractors reclaim all wash water. We’ve also eliminated the use of acids in our trailer-washing process to help prevent metals from seeping into the groundwater.
Refrigerant capture—When servicing our air conditioning units, we always capture Freon and other harmful refrigerants to ensure their disposal in an environmentally friendly manner.
Better tank systems—Most of our in-house fueling facilities use above-ground tank systems, which meet or exceed all federal, state and local regulations. Many are equipped with canopies to help prevent storm-water runoff, as well as 5-minute timers to limit potential spillage.
Maintenance—We follow more efficient schedules for routine vehicle maintenance, which reduces the amount of waste oil to recycle.
Mosquito prevention—Our mounted wheel program helps prevent the build-up of standing water in tires, which prevents attracting mosquitoes that can carry the West Nile virus.
Wheel refurbishing—We’ve reduced the use of aerosols in our shops by sending our wheels to responsible outside contractors for restoration.
Earth-friendly parts washing—Estes shops feature self-contained sinks for washing vehicle parts, which helps prevent oil and chemicals from entering the environment.
Solar is a nonpolluting, renewable resource that delivers reliable power year round. So far we’ve installed solar-power systems in our Baltimore, MD; Elkton, MD; and Greensboro, NC, terminals. Learn more.
The results are promising:
Greensboro’s system includes 2,760 solar panels that generate about 1,000 megawatt-hours of electricity each year. Meanwhile, Baltimore’s system generates about 320 megawatt-hours from its 1,100 rooftop panels. Another 360 megawatt-hours come from Elkton’s 1,232 panels.
Approximately 93% of the Elkton terminal’s annual energy needs are met though its solar power system, which accounts for an annual reduction in CO2 emissions of about 280 tons. Baltimore’s system covers the reduction of about another 250 tons each year.
Greensboro’s system is designed to produce enough clean electricity to power all of the buildings on site. It accounts for the annual reduction in CO2 emissions of about 775 tons.
The following comparable equivalents illustrate the magnitude of our solar power systems’ combined environmental impact through reduced annual CO2 emissions:
Making environmentally responsible decisions about fuel usage is an important part of Estes’ green program. We’ve successfully lessened our environmental impact by using cleaner fuels and taking steps to improve our equipment’s fuel efficiency. By making sure we carry freight as efficiently as possible, we minimize our truck’s fuel consumption and carbon dioxide emissions. Learn more.
Bio-diesel—We are using B5 blend bio-diesel in some states.
ULSD fuel—We only use ULSD (Ultra-Low-Sulfur Diesel) fuel, which reduces the emission of particulate matter and nitrogen oxides.
Conversion to propane—Our forklifts have been converted from gasoline/diesel to propane.
PrePass and EZ Pass—Our drivers utilize PrePass and EZ Pass to bypass weigh stations and toll plazas, which means that our trucks spend less time idling.
Efficient Driving— Every Estes tractor is equipped with computerized PeopleNet® hardware that records driver inefficiencies that can waste fuel, such as long idle, excess speed and over-RPM metrics.
Fuel economy monitors—Estes trucks are equipped with technology for tracking and measuring fuel economy. We can then address any issues that might lead to wasted fuel.
Idle shutdown system—Our tractors are equipped with idle shutdown systems set at 3 minutes.
Improved aerodynamics—Estes will begin installing aerodynamic skirts on more than 6,700 trailers by the end of 2014, which should cut fuel consumption by about 4–5%. Our equipment also features air farings and side farings, which further improves vehicle aerodynamics.
Reduced oil consumption—We use synthetic lubricants for all drivetrains (transmissions and rears) to reduce friction and improve fuel mileage.
Low-profile tires—We’re converting our entire fleet to low-profile tires to reduce rolling resistance and lower fuel consumption.
Speed management—We’ve reduced power-unit speed from 68 to 65 mph to increase vehicle fuel mileage.
Weight reduction—By using aluminum rather than steel fuel tanks, we’ve reduced power unit weight by 65 pounds, which improves fuel economy.
Auxiliary Power Unit (APU)—The APU in our sleeper cabs cuts fuel consumption significantly by reducing engine idle time.
Card-locked fuel systems—We use card-locked systems for our vehicles to foil wasteful, unauthorized access to fuel. Our systems also employ breakaway hoses to help prevent potential soil and water pollution from fuel spills.
Innovative route-planning software—Estes uses sophisticated route-planning software to ensure that we’re carrying freight as efficiently as possible, thereby limiting greenhouse gas emissions and unnecessary fuel consumption
Fewer empty loads—We’ve reduced our empty loads by over 25% since 2007, which has cut freight carbon emissions by more than 7,744 tons.
Intermodal transport—Since 2007, we’ve increased by more than 300% the number of miles we carry freight via rail. This has led to an additional 11,434-ton reduction of our freight carbon emissions.
Effective driver behaviors, efficient engines and streamlined routing are crucial for limiting a trucking company’s carbon footprint. Estes’ strategy for reducing greenhouse gas emissions addresses these fundamentals. Learn more.
