The Benefits of Switching Your Waste Management Fleet to Natural Gas

Waste management is one of the most vital services for communities throughout the U.S., but it does not come without a cost. In a time when fuel costs have rendered leisurely driving cost-prohibitive, fuel costs in the public-services sector can be problematic for refuse fleets and taxpaying residents of local communities. Environmental issues that have cast traditional fuel options in an unfavorable light have compounded these problems.

Thankfully, refuse fleets now have an alternative to conventional fuels like diesel. Compressed natural gas is better for the environment, easier on engines and more readily available at modest prices throughout the U.S. Many state agencies have recognized the benefits of natural gas, and some of them have begun offering incentives to fleet owners who agree to switch from diesel to natural gas.

Despite these advantages, many fleet managers have thus far resisted the switch, in some cases due to the upfront cost of trucks that run on natural gas. The following article explores the benefits of natural gas garbage trucks and why it is in the best interest of refuse fleets to make the switch.

Why Are Refuse Truck Fleets Switching to Natural Gas?

All across the United States, garbage trucks rely on diesel and biodiesel fuel to drive around from neighborhood to neighborhood and collect waste and recyclables. The emissions these trucks produce contribute to the air quality problems residents experience in some of the nation's more heavily trafficked towns and cities.

Overall, garbage trucks consume about 1.2 billion gallons of diesel annually. As a result of this reliance on diesel by the refuse-trucking industry, the U.S. emits approximately 27 billion pounds of CO2 greenhouse gas, solely for garbage collection. These figures could easily be lower if more garbage trucking companies consider alternatives.

The problems associated with diesel fuel and its widespread use among garbage fleets have spurred interest in natural gas fuels, which are less expensive and release fewer emissions. As more garbage trucks begin using natural gas fuels, towns and cities could enjoy cleaner air because the exhaust pipes of refuse vehicles would be emitting fewer gases.

Natural Gas Garbage Trucks

Natural gas fuels fall into two categories: compressed natural gas (CNG) and liquefied natural gas (LNG). CNG is the more economical and accessible option for U.S.-based refuse fleets. In recent years, the cylinder designs in refuse trucks have allowed for greater CNG efficiency.

LNG is the less accessible option for refuse fleets because it is costlier to procure and not as readily available across the U.S. Consequently, refuse fleets would face challenges trying to enact LNG adoption on a broad scale, both in terms of storage and fueling. Therefore, CNG has become the diesel alternative of choice among the refuse-trucking industry.

Garbage trucks, in general, have suffered from lackluster fuel efficiency, a problem the rising costs of diesel fuel have compounded in recent years. In general, garbage trucks burn through a gallon of diesel fuel every three miles. When you multiply this by the per-gallon price of diesel — which hovers around $4 — it becomes apparent why refuse fleets are burning at both ends.

Compared to diesel, one of the key advantages of compressed natural gas is the latter's relatively low cost. Unlike diesel, which has remained relatively costly, CNG has come down in price, thanks in part to a competitive, deregulated domestic market that has made the fueling alternative more readily available to refuse fleets. The increased presence of shale gas resources has also spurred this trend, making CNG the more practical option in an era of expensive diesel and gasoline.

The biggest impediment to widespread adoption of natural gas has been the cost factor in setting up fueling stations that offer CNG. Thankfully, refuse fleets can get around this problem by hiring third-party suppliers. A fleet company could get its on-site fuel tank filled by an outbound CNG supplier regularly, thereby preventing the need for local service stations.

The other major roadblock is the cost of natural gas vehicles (NGVs), which cost upwards of $30,000 to $50,000 more than fleet trucks that run on diesel. Despite this, the savings fleets can accumulate over time can easily earn back the upfront cost of trucks that run on natural gas. NGVs are also kinder to our environment because the high-pressure fuel systems of such trucks emit fewer gases.

The Advantages of Switching to CNG

Refuse fleets can save money and reduce their carbon footprint by switching from diesel to compressed natural gas. With CNG, fleets emit less and spend less on fuel costs. Thanks to the domestic availability of CNG, the trend is also beneficial to the U.S. economy. Moreover, natural gas is cleaner and more efficient and thus a healthier option for refuse vehicles. There are several advantages to natural gas garbage trucks, which we'll explore in more detail below.

The Advantages of Switching to CNG

1. Better on the Environment

One of the most significant benefits of NGVs and CNG is the low amount of emissions natural gas releases compared to diesel. From an environmental standpoint, refuse fleets benefit in the following ways by switching to CNG.

  • Reduced emissions: Garbage trucks that use CNG emit fewer greenhouse gases. As such, the fleets that adopt NGVs are helping the nation reduce its carbon footprint. Overall, the trend toward CNG has made the garbage-collection industry one of the more eco-friendly branches of the public sector.
  • Less impact on residents: Vehicle emissions can make ambient conditions unhealthy for residents of congested cities. For children who grow up near busy streets, the constant flow of diesel-burning vehicles can have adverse health effects, some that might only manifest at a later age. By switching to natural gas, refuse fleets are helping build a better, cleaner future for the nation's children.
  • Improved public image: In an age of increased environmental consciousness among the public at large, any company that adopts eco-minded practices tends to cultivate a more favorable public image. As more and more refuse fleets switch to CNG, the industry as a whole could become one of the most favorably viewed public-service sectors.

In the decades to come, history may come to view natural gas-powered refuse trucks as a major catalyst in the move away from gas-emitting vehicles.

2. Lower Cost

Lower Fueling Costs

Garbage truck fleet fueling is less expensive with natural gas. Compared to competing forms of fuel, CNG costs an average of $1.50 to $2 less per gallon. When you multiply that savings for each vehicle in a fleet over the course of a given year, the savings that accumulate with CNG could be immensely rewarding for refuse fleets. From a savings standpoint, the lower costs associated with CNG work in the following ways.

  • Reduced operating expenses: Fuel is the lifeblood of any fleet. To travel the distances required for garbage collections and disposals, refuse trucks require fuel in great quantities. Natural gas can slash the costs associated with fueling expenses by as much as half, allowing fleets to allocate resources in other areas.
  • Savings for taxpayers: In some jurisdictions, taxpayers could end up saving money on their garbage collection services if more refuse fleets switch to CNG, all thanks to the lower cost of natural gas.
  • Higher pay: For refuse vehicle drivers, the lower costs of CNG could result in pay increases. When fleet companies can save on fuel expenses, they can invest that savings back into things such as vehicle maintenance, new vehicles and higher wages.

Even with the initial cost of switching a garbage truck fleet to natural gas, companies could easily recoup the up-front price of the vehicles within a year, after taking all the potential savings into account.

3. Reduced Reliance on Foreign Oil

The move toward CNG is slowly loosening America's reliance on foreign oil, due to the ample domestic supply of natural gas, which has become more readily available over the past two decades thanks to deregulation and increased competition. As more U.S. suppliers offer natural gas, fleet companies and other entities in the public-services sector stand to reap the following benefits.

  • Avoid price fluctuations: The price of foreign oil is often due to political strife in the oil-rich Middle East. Oil imports are more difficult to procure when the supplying nations are hostile towards the U.S. As war and unrest continue, oil imports become increasingly costly. With the increased availability of domestically cultivated natural gas, refuse fleets can avoid the pricing issues that stem from the international situation.
  • Support domestic suppliers: From an economic standpoint, it is best to support companies that operate here in the U.S. What comes around goes around, and domestic entities mutually benefit when they purchase goods and services from fellow domestic entities.
  • Invest in the domestic economy: When you purchase from U.S.-based natural gas suppliers, the money you spend on fuel goes back into the nation's economy and infrastructure. So, instead of earning more money for some nation halfway around the world, your purchase on fuel can now help make America a wealthier nation.

The trend of refuse trucks switching to natural gas is one of many moves that could help make the U.S. a more self-sufficient country in the future.

4. Cleaner Burning and Better on Engines

For the same reason compressed natural gas is healthier for the environment, the fuel is also better for vehicles. CNG is a cleaner-burning fuel than diesel. CNG leaves fewer trace elements in vehicle engines, thus reducing the need for maintenance. You can get more mileage on a tank of natural gas and operate a truck for a longer span with little or no need for engine repairs or parts replacements. As such, companies can earn the upfront cost of CNG garbage trucks back in due time, thanks to the relative lack of performance issues they are likely to encounter over the course of a typical year.

How to Switch Your Garbage Truck Fleet to Natural Gas

Over time, switching your garbage truck fleet to natural gas could present numerous benefits. Initially, however, the upfront costs can make the undertaking somewhat daunting, especially if you operate a small fleet. The best way to go about the switch is to look for incentive opportunities and find CNG suppliers that offer good deals to fleets in your area.

Switch Your Garbage Truck Fleet to CNG

Knowing the benefits of natural gas-powered refuse trucks, some states offer grants and other funding opportunities to encourage more fleets to make the switch. California, Florida and Texas have all enacted programs that give fleets financial incentives to purchase natural gas vehicles. Other states are offering incentives to encourage developers to construct natural gas fuel facilities. The discovery of natural gas reserves in the U.S. has spurred the latter move, a development that is freeing North America from its longstanding dependency on foreign oil.

Fleets can also switch to natural gas by seeking local suppliers that offer good deals and offers. For example, Shipley Energy offers fuel storage tanks for lease. Smaller fleets could use this opportunity to acclimate to CNG and then invest the resulting savings in CNG garbage trucks.

Why Choose Shipley Energy for Natural Gas Fleet Fueling?

The U.S. is currently home to more than 900 natural gas stations. Still, the spread of compressed natural gas has remained relatively unknown among many fleets that continue to operate on old-fashioned fuel.
