Waste and recycling company Republic Services, Inc. has deployed 23 compressed natural gas (CNG) solid waste and recycling trucks to serve customers throughout the Twin Cities area. The new CNG fleet will replace older diesel powered trucks. Natural gas fueling stations enable CNG trucks to fuel during non-peak hours.
Black carbon and tropospheric ozone are harmful air pollutants that also contribute to climate change. Reducing black carbon and tropospheric ozone now will slow the rate of climate change within the first half of this century, the study said.
has brought 67 Compressed Natural Gas (CNG) solid waste and recycling trucks to serve customers throughout southern New Jersey and in Philadelphia. The new CNG fleet will replace older diesel-powered trucks. Continuing its string of local deployments ( earlier post ) Republic Services, Inc.
As part of the settlement, the company will spend an additional $6 million to reduce air pollution from diesel vehicle emissions in Texas City and the surrounding area. BP will eliminate approximately 51,000 pounds of HCFCs by retrofitting industrial and commercial cooling appliances at Texas City to use non-ozone-depleting refrigerants.
The program funds projects to encourage the development and use of new technologies and alternative and renewable fuels, including electricity, natural gas, biomethane, hydrogen, and gasoline and diesel substitutes, such as cellulosic ethanol (derived from woody materials, including agricultural waste), and biodiesel from waste grease.
HFCs are powerful greenhouse gases originally developed as substitutes for ozone-depleting chemicals. A binding legal agreement exists that can cut HFCs now—the Montreal Protocol ozone treaty—and many alternatives to HFCs have already been developed and are waiting for the right regulatory incentive from the Montreal Protocol to be deployed.
These technologies include, but are not limited to, advanced aftertreatment and waste heat recovery; lean-burn plus lean-NO x emissions traps; integration of zero-emission miles technologies; further refinements in reducing friction and parasitic energy losses; and widespread utilization of renewable and natural gas and hydrogen blends.
A study by researchers at Lund University in Sweden found that Swedish biofuels produce between 65 and 148% less greenhouse gas emissions than gasoline and diesel, even when direct and indirect land use changes are taken into account. Co-production of biogas and ethanol from wheat was also analyzed.
Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. From 2007 to 2008, the share of ethanol in global gasoline type fuel use was estimated to increase from 3.78% to 5.46%, and the share of biodiesel in global diesel type fuel use from 0.93% to 1.5%.
The committee that wrote the report focused on monetizing the damage of major air pollutants—sulfur dioxide, nitrogen oxides, ozone, and particulate matter—on human health, grain crops and timber yields, buildings, and recreation.
These reductions have come from strong efforts to reduce on-road vehicle emissions, especially diesel particulate matter. The State’s organic waste should be put to beneficial use, such as for soil amendments/compost, electrical generation, transportation fuel, and pipeline-injected renewable natural gas.
Development of sustainable communities strategies can also provide an opportunity for associated criteria pollutant emission reductions that will be needed to attain air quality standards for ozone and particulate matter as well as reduce near-roadway exposures.
In order to achieve the 2008 Ozone National Ambient Air Quality Standards set by US EPA, CARB estimates that the South Coast Air Basin alone (including Los Angeles) will need an 80% reduction in NO x emissions by 2031. CARB said it looked forward to continued cooperation with the federal agencies on this long-term effort.
Mikhail Chester and Arpad Horvath inventoried on-road, rail, and air travel to determine energy consumption, greenhouse gas (GHG) emissions, and criteria air pollutant (CAP) emissions (excluding PM, lead, and ozone due to lack of data). Peak urban diesel buses showed the best overall energy consumption and GHG emissions per PKT.
As the trend toward cleaner technologies with reduced exhaust emissions continues through the use of catalytic converters, diesel particulate filters (DPF), and improved fuels and engines, non-exhaust PM will soon surpass exhaust emissions and may well become dominant by 2020 both in terms of emissions and contributions to air quality.
The fundamental diesel engine research program pursuing advanced technologies and combustion processes and engine architectures to achieve 55 percent BTE should continue to be a focus of the 21CTP engine activities. If necessary, the next-generation code development should be adjusted.
Fast action on pollutants such as black carbon, ground-level ozone and methane may help limit near term global temperature rise and significantly increase the chances of keeping temperature rise below 2 °C (3.6 °F)—and Waste management. Diesel particle filters for road and off-road vehicles. for 2030 and beyond.
Methane is both a potent greenhouse gas and an important precursor to ground-level ozone. Ozone, a key component of smog and also a greenhouse gas, damages crops and human health. Tropospheric ozone and black carbon (BC) contribute to degraded air quality and global warming.
The California Air Resources Board (CARB) approved a plan to mitigate statewide harm from more than 10,000 tons of smog-causing pollutants released in the state due to Volkswagen’s (VW) use of illegal “defeat devices” in diesel passenger cars. liter diesel passenger vehicles with illegal software in the United States. Background.
Wastes from cattle, chickens and other livestock include nitrogen. Farm machines burning oil, gasoline and diesel release nitrogen to the air. But excess nitrogen is emitted from soils, seeps into groundwater and runs off into surface waters.
A new report prepared by the World Bank at the request of the G8 identifies ways that the World Bank can do more through its projects to reduce the emission of short-lived climate pollutants (SLCPs): black carbon, methane, tropospheric ozone, and fluorinated gases known as HFCs. Over the six-year period of the review (FY2007-2012), 7.7
