Sustainable Operations

These trucks weigh tens of thousands of pounds, but our drivers and technicians know how to make them tread lightly on the landscape.
Throughout the northeast we operate over 130 facilities and over 843 collection vehicles. To make these operations more sustainable, we are investing in fuel efficiency and alternative fuel vehicles, while maintaining a daily focus on meeting and exceeding our environmental compliance requirements.

Fuel Efficiency

goal Fuel Efficiency

Improve our fuel efficiency, reducing our Gigajoules (GJ) of fuel consumed per ton of waste and recycling collected by 20% below a 2019 baseline

For the past five years, we have worked to standardize and modernize our fleet. The effort has driven significant improvements in our maintenance and productivity metrics and has substantially reduced the average age and size of our fleet. By phasing out and replacing older equipment with newer models, we have improved our emission controls and overall efficiency. We are now turning our focus to increasing our level of automation.

We expect to achieve our next wave of efficiency improvements as we deploy the latest automation technology and improved routing capabilities throughout our fleet. These measures will also deliver important safety benefits. In test markets, the preliminary results have shown a significant improvement in worker safety metrics, a 30% reduction in miles driven, and a 19% increase in driver productivity.

By 2030, we aim to improve the fuel efficiency of our waste and recycling collection operations by 20%. We track our performance in terms of Gigajoules of fuel per ton of material collected, which we aim to reduce from 0.495 to 0.396. When we achieve this goal, we expect to be saving over 1 million gallons of diesel fuel per year.

Alternative Fuels

Alternative fuel technology for refuse vehicles has advanced markedly in recent years and we look forward to deploying more compressed natural gas (CNG) and electric vehicles in our fleet over the coming years.

Compressed Natural Gas (CNG) vehicles play an important role in our industry’s transition away from diesel fuel reliance. These CNG trucks have a lower carbon footprint and a cleaner emission profile compared to standard diesel trucks. They also have the ability to run on Renewable Natural Gas (RNG), opening the possibility that our trucks may one day be fueled by the gas produced at our landfills.

Today CNG vehicles make up 4% of our routed vehicle fleet. In markets with available CNG fueling infrastructure, 19.6% of our routed fleet runs on CNG.

Electric vehicle technology continues to advance and is becoming increasingly viable for heavy-duty refuse fleets such as ours. Improvements in battery capacity, vehicle range, and power will help enable the adoption of electric trucks in our industry.

We intend to pilot one or more electric refuse trucks in 2021 to evaluate the progress of the technology and its ability to meet the demands of our collection routes.

Environmental Compliance

goal Environmental Compliance

Maintain strong environmental compliance, reducing our number of sanctions including notices of violation, enforcement orders, and notices of non-compliance/deficiencies

Compliance with environmental laws and regulations is a core expectation for each of our operations and a daily responsibility of each Casella employee. Our engineering and environmental professionals work with our facility operating teams to continuously manage to this standard.

Our commitment to compliance is best understood within the context of our published environmental policy, which outlines seven key environmental leadership statements on the topics of resource conservation and renewal, environmental compliance, air and climate protection, water protection, land protection, community engagement, and leadership and continuous improvement. Our environmental policy is available for download on our website or in Appendix C of this report.

Greening Our Yellow Iron

Our push for fuel efficiency extends to our offroad fleet. Today, three of our landfills are running Cat® electric drive dozers, which the manufacturer reports can yield a fuel savings of up to 35%. Additional fuel efficiencies have come from upgrading our landfill compactor equipment.

Having adopted the new technology, the local operating teams report that the equipment works very well while consuming less fuel than the machines they replaced. We will deploy the electric drive dozer technology at two more locations in 2021.
