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.
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 Company owns two local recycling processing centers, and is a leading collector of industrial waste and commercial organic food waste.
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.
They are employing a special microbial fermentation process similar to biogas production to produce hydrogen directly from organic waste. Micropollutants such as pharmaceuticals, pesticides and cosmetics can be removed from wastewater when ozone is introduced. KG in the HyPerFerMent I project to produce renewable hydrogen from biomass.
On a per-storage basis, the team found that the NiMH technology was found to have the highest environmental impact, followed by NCM and then LFP, for all categories considered except ozone depletion potential. They also found higher life cycle global warming emissions than have been previously reported.
Researchers at North Carolina State University are developing an ozone-based pre-treatment technique (ozonolysis) to release sugars from the energy grass miscanthus for production into renewable fuels or chemicals with minimal generation of chemical waste streams and degradation of the carbohydrate components.
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.
The first is the Vehicle Technologies Office (VTO), which aims to advance combustion engine technology and simultaneously reduce criteria emissions, such as carbon monoxide, nitrogen oxides and ozone.
The settlement addresses the company’s noncompliance with a 2001 consent decree and Clean Air Act regulations requiring strict controls on benzene and benzene-containing wastes generated during petroleum refining operations.
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.
The fuels studied were: biogas from sugar beet, ley crops, maize and waste products in the form of household waste, industrial waste and manure; biodiesel from rapeseed; ethanol from wheat and sugar beet; and ethanol from Brazilian sugar cane. Co-production of biogas and ethanol from wheat was also analyzed.
That the reduction has not materialized—and that global emissions have instead risen—is a puzzle, and may have implications for the Montreal Protocol, the international treaty that was designed to protect the stratospheric ozone layer. —Dr Stanley. Resources. Stanley, D. Krummel, D. O’Doherty, P. Salameh, P. Simmonds, R.
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.
Here, RME show advantages for primary energy and GHG, but disadvantages in terms of acidification, eutrophication and ozone depletion. use biomass to produce a material and the recover the energy content of the resulting waste); and mineral-based solar energy systems.

The gas and hydrocarbons can then be treated and used or sold, avoiding the waste of natural resources that cannot be renewed. Those benefits include reductions in health effects related to fine particle pollution, ozone and air toxics, along with improvements in visibility.
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. Organic wastes converted to biogas could supply enough renewable natural gas for about 2 million residential units.
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.
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”.
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.
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). 83% of rail passenger kilometers are performed by metropolitan systems (with Amtrak serving the remaining).
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.
Specifically, they proposed a method to assess the contribution of EVs to urban air quality in Belgium, compared to conventional vehicles of the same weight class; they modeled the effect on human toxicity (HT), photochemical ozone formation (POF) and particulate matter formation (PMF). Air Waste Manag. Denier van der Gon, H.A.C.,
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. These new targets need to be set for the research efforts.
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. As we confront the enormous challenge of climate change, we should take inspiration from even the most unlikely sources.
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. Pellet stoves and boilers, using fuel made from recycled wood waste or.
A) shows the base case peak concentrations for O 3 (ozone), ClNO and HCl in parts-per-billion by volume (ppbv). (B) Under extreme circumstances, this previously unknown chemistry could account for up to 40 parts per billion (ppb) of ozone; the current US Environmental Protection Agency (EPA) 8-hour average standard is 75 ppb.
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.
Im gonna post a couple excerpts here: Most ozone pollution is caused by motor vehicles, which account for 72% of nitrogen oxides and 52% of reactive hydrocarbons (principal components of smog). (7, Nuclear waste is a problem much harder to solve than CO2, and dams have quite an impact in the environment.
Excess NO x emissions are a major public health concern in California, because they are a key ingredient in formation of ozone (smog), CARB notes. More than 10 million Californians live in areas in extreme non-compliance areas for ozone. Ozone is a contributor to asthma attacks, cardio-pulmonary disease and premature death.
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
Wastes from cattle, chickens and other livestock include nitrogen. But excess nitrogen is emitted from soils, seeps into groundwater and runs off into surface waters. Farm machines burning oil, gasoline and diesel release nitrogen to the air.
The update identifies eight key sectors for ongoing action: Energy; Transportation, fuels, land use and infrastructure; Agriculture; Water; Waste management; Natural lands; Short-Lived Climate Pollutants (such as methane and black carbon); and Green Buildings. Transportation. The 2016 SIPs will outline attainment strategies through 2032.
As a BYD investor, I'm upset to see them waste so much money on dead technologies like PHEVs/EREVs. Swapping out CO2 for other toxins like ozone and nitrogen oxides is not a solution. As the economies of scale disappear for ICE, so too will they disappear for hybrids that depend on the existence of ICE.

In general, biofuels made from organic waste are environmentally more benign than those from energy crops. A few studies also include other relevant impact indicators as acidification potential, eutrophication potential, ozone depletion potential and various toxicity potentials. However very few studies include water use impacts.
