Shaw Brothers approach to reducing our environmental impact means looking at all aspects of the business and how we can integrate new solutions to create meaningful change to our environment.
Shaw Brothers is currently in the process of building a new solar farm as part of the reclamation of an old gravel pit. Every year, this 3.2-megawatt array will generate 4 million kilowatt-hours of electricity. This electricity generation will cover all of Shaw Brothers usage including our shop, asphalt plant, both stationary crushers and return extra power back into the grid.
Our Asphalt Plant, purchased in 2013 is one of the most environmentally friendly plants in New England. The plant is powered by natural gas which emits 99% less Sulphur oxide, 80% less nitrogen oxide, 40% less CO2 and no heavy metals or soot particles.
Our custom-made mix designs contain 20% to 50% reclaimed asphalt pavement (RAP) which reduces the need for virgin material by the same amount. By using recycled pavement, we reduce the amount of liquid asphalt needed by over 20%.
In 2018 Shaw Brothers installed a new Telsmith Crushing Plant. The extensive conveyor system will reduce emissions from trucking and loading equipment and has the ability to stock pile over 3/4 a million tons of various stone and gravel sizes eliminating the need for rehandling thus saving emissions.
We also converted our Dayton crushing plant from a diesel-powered generator to electric power.
Shaw Brothers was the first contractor in northern New England to purchase a track-mounted portable crusher with a magnetic separator. We now have ten portable crushing plants, eight of them on tracks, enabling us to work multiple sites simultaneously or maximize recycling throughput at one large site.
Track-mounted portable crushers allow us to recycle materials on the project site, so we don’t need to haul construction demolition debris somewhere else for processing. In many cases, recycled aggregate can be used on the same project to further minimize transportation cost to and from the site and minimize greenhouse gas emissions.
In 2019 Shaw Brothers purchased the first 988K XE CAT Loader in New England. This electric drive loader will save 4,250 gallons of diesel fuel over the prior 988 H loader that Shaw Brothers owned.
Over 50% of our equipment and trucks are equipped with Tier 4 Diesel engines. These new engines meet the strictest EPA emission standards for particulate matter, black soot and nitrogen oxides.
We have installed new LED lights in our shop, office and parking lot to reduce electricity usage.
• In the office we installed 203 new UltraLED Edge-Lit Panels have reduced our energy usage by 64% per panel.
• In the shop we installed 120, I-Beam IBH High Bay reducing our energy consumption by 60% per fixture.
• In our parking lot we installed 36 new LED V4 Shoe Box light reducing energy and maintenance costs up to 90%
We heat our shop and office with waste oil, recycling 12,000 gallons of waste oil every year.
