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. Republic operates a fleet of more than 1,400 CNG vehicles and 26 natural gas fueling stations nationwide.
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. One of the more lasting contributions we can make in our community is to protect the environment by reducing ozone-forming emissions wherever possible.
Five technology paths for very-low-NO x and GHG emissions from heavy-duty natural gas engines. The “Pathways to Near-Zero-Emission Natural Gas Heavy Duty Vehicles” report, authored by GNA on behalf of Southern California Gas Co. Click to enlarge. Click to enlarge. Background. Click to enlarge.
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.
BP will convert approximately 100 diesel municipal vehicles, including several dozen school buses, to operate on compressed or liquefied natural gas and will construct four refueling stations for the converted vehicles. Exposure to asbestos, a known human carcinogen, can cause asbestosis and two types of cancer: lung cancer and mesothelioma.
The US Environmental Protection Agency (EPA) released its latest set of proposed standards to reduce emissions of methane and volatile organic compounds (VOCs) from the oil and natural gas industry. The proposal also includes incentives to spur the oil and gas industry to minimize leaks.
Despite reports that global emissions of the potent greenhouse gas, HFC-23, were almost eliminated in 2017, an international team of scientists, led by the University of Bristol, has found atmospheric levels growing at record values. This gas has very few industrial applications. —Dr Stanley. Resources. Stanley, D. Krummel, D.
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. 68% from biodiesel (RME).
Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. An important analytical issue that needs to be addressed, the report notes, is the lack of lifecycle assessment studies focusing on a wider set of environmental impact indicators than greenhouse gas emissions.
The FY 2011-2012 plan focused primarily on five areas of interest: sustainable communities; behavior and technology adoption; health and air pollution exposures; air pollution science; and greenhouse gas targets. ARB will also consider projects outside of these areas, to the extent that they provide clear and direct support to its mission.
They focused their comparison on techniques used in a three-dimensional model commonly used by environmental agencies to simulate ozone, particulate matter, and atmospheric acid concentrations, and develop effective emission reduction strategies. Stockwell, Emily Saunders, Wendy S. Goliff & Rosa M.
The major sources of methane in California are livestock (~30% of the state’s methane emissions), followed by landfills and oil and gas production. Methane is 72 times more efficient at trapping heat in the atmosphere than CO 2 , which is the most prevalent global warming gas. CO 2 remains in the atmosphere for up to a century.
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. Most vehicle and fuel combinations had similar levels of greenhouse gas emissions in 2005.
Dow Chemical Company will partner with SNL to reduce the thermal conductivity of insulating foam polyurethane products while using less polymer in its products in a project titled “Predictive Modeling of Polyurethane Foam Processes to Optimize Thermal Performance and Reduce Waste”. VAST Power Systems, Inc.
Methyl halides are naturally produced by a number of organisms; the enzyme responsible for this production—methyl halide transferase (MHT)—has been studied in the context of the environmental production of methyl halides, which contribute to ozone depletion. cerevisiae for metabolism of toxic waste products.
The US Environmental Protection Agency (EPA) and the US Department of Transportation’s National Highway Traffic Safety Administration (NHTSA) jointly released the finalized Phase 2 greenhouse gas and fuel efficiency standards for medium- and heavy-duty trucks. The final standards are expected to lower CO 2 emissions by approximately 1.1
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). Chester and Horvath (2009).
Take, for example, the tens of thousands of fossil-fueled ships that chug across the ocean, spewing plumes of pollutants that contribute to acid rain, ozone depletion, respiratory ailments, and global warming. not a replacement for reducing greenhouse gas emissions, which is imperative. Solar climate intervention is.
California’s and, potentially, EPA’s move toward further heavy-duty NO x reductions to meet National Ambient Air Quality Standards for ozone will be critical. The DOE should continue to explore how the United States might use its abundant petroleum, natural gas, and biofuel resources in the most efficient manner.
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 of oil and natural gas. Reduced gas leakage from long-distance transmission pipeline.
This SAE spec would make it so you could go to a gas station and they would have the proper voltage and plug for your car. but its never even been close to the amount of garbage that gas power vehicles produce. Nuclear waste is a problem much harder to solve than CO2, and dams have quite an impact in the environment.
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 released the draft proposed first update to the AB 32 Scoping Plan, which guides development and implementation of California’s greenhouse gas emission reduction programs. The Air Resources Board is required to update the Scoping Plan every five years. Transportation.
In general, biofuels made from organic waste are environmentally more benign than those from energy crops. Low-input cultivation of perennial plants, e.g. from short-rotation forestry and grasslands, may be an effective source of cellulosic biomass and provide environmental benefits (reduced pollution and lower greenhouse gas emissions).
