Clean Fuels (Alternative Fuels) In Refuse Collection Trucks: The Compelling Case for Converting to CNG or LNG from Diesel or Biodiesel

Introduction & The Challenge:
Everyday in every major City, Town or Community, one vehicle type, besides school buses, passes through every residential street - the garbage truck. Garbage Trucks (aka as Refuse Collection Trucks) operate daily in various parts of every residential part of every City, collection garbage, refuse or recycling. In most cities or twons, these trucks are still powered by traditional diesel or biodiesel, spewwing tons of carcingens into our atmosphere and our communities.

Those black plumes of smoke emit dangerous levels of CO2 and in the United States approximately 180,000 refuse trucks operate and burn approximately 1.2 billion gallons of diesel fuel a year, releasing almost 27 billion pounds of the greenhouse gas, CO2. Every gallon of diesel fuel burnt emits more than 22 pounds of CO2.

WIH Resource Group , a global leader in developing Client-specific Environmental and Logistical Solutions, has developed an industry White Paper on the subject focusing on what Federal, State and local grants, tax incentives and other means are available to assist both private sector waste management garbage companies as well as governmental agencies convert their diesel powered garbage trucks to cleaner, more environmentally firendly CNG or LNG alternative fueled fleets.

The Solution:
CNG is natural gas that has been compressed into a high-pressure container for transportation. Since the 1960s, CNG has become a vehicle fuel alternative to oil-based gasoline and diesel fuel. The International Association for Natural Gas Vehicles estimates that more than one million vehicles worldwide operate on CNG.

  • Dec 27 2011: A term like "27 billion pounds of ... CO2" doesn't mean much to me, or, I suspect, to most others. 13.5 millions tons would be a small improvement, but how do I visualize the weight of a gas anyway? I think such figures should be given in something like percent of total CO2 pollution, or of CO2 presently in the atmosphere.

    The main problem with natural gas (also a greenhouse gas, about 22 more powerful than CO2) is the potential leakage. It's said if changed to general use of CO2 instead of other fossil fuels, and more than 2% were to leak from pipes and equipment, it would cause more global warming that CO2. Meanwhile, the industry says it expects to lose about 3%. Bottom line, there's no really green fuel, not even biofuels.

    The problem we really need to deal with is drastically reversing global human population growth, instead of trying to turn the Earth into a monocullture of humans and their support systems. Nature will take care of that soon, but I'd kind of like to avoid Nature's methods.
