Cement manufacturing is one of the most energy intensive processes and is accountable for substantial pollutant emissions. Increasing energy costs compel stakeholders and researchers to search for alternative options to improve energy performance and reduce CO2 emissions. Alternative fuels offer a realistic solution towards the reduction of the usage of fossil fuels and the mitigation of pollut...

In order to reduce the atmospheric pollution emitted by automobiles, control devices are being incorporated in the vehicles in many countries. This has resulted in a reduced vehicle mileage to the extent of about fifteen percent. Without the introduction of new technology, any further reduction in emission levels would be expected to extract payment in the form of further fuel economy losses. I...

BACKGROUND Consequences of exposure to household air pollution (HAP) from biomass fuels used for cooking on neonatal deaths and stillbirths is poorly understood. In a large multi-country observational study, we examined whether exposure to HAP was associated with perinatal mortality (stillbirths from gestation week 20 and deaths through day 7 of life) as well as when the deaths occurred (macera...

The need to replace fossil fuels with biofuels has become necessary due increasing release of greenhouse gases and particulate matter by combusting fuels. Biofuels are better options compared fossil-based the availability cheap abundant renewable feedstock. Due large number possible fuel structures clustered in databases, solo experimental search strategies cannot identify a clean efficient mol...

The emission of carbon monoxide, greenhouse gases (e.g., dioxides), hydrocarbon, and particulate matter can be reduced by applying oxygenated additives as a blend to combustible hydrocarbon fuels. However, conventional oxygenates, such dimethyl ether methyl t-butyl ether, are sourced from non-renewable feedstocks. This study presents critical review on the catalytic synthesis furanic compounds,...

Ungulates exert a strong influence on the composition and diversity of vegetation communities. However, little is known about how ungulate browsing pressure interacts with episodic disturbances such as fire and stand thinning. We assessed shrub responses to variable browsing pressure by cattle and elk in fuels treated (mechanical removal of fuels followed by prescribed burning) and non-fuels tr...

 Cost-competitive with petroleum fuels  Long-term stable price for budget forecasting  Made from sustainable, renewable Biomass residuals  Storable and pumpable liquid similar to petroleum fuels  Clean burning fuel without the sulfur and particulates from petroleum fuels  Low greenhouse gas emissions Sustainability issues have become an important part of the supply chain for operati...

Sustainable development is the common goal of current concepts bioeconomy and circular economy. In this sense, biorefineries platforms are a strategic factor to increase in economic balance. The incorporation renewable sources produce fuels, chemicals, energy, includes sustainability, reduction greenhouse gases (GHG), creating more manufacturing jobs fostering advancement regional social system...

Concerns about depletion of fossil fuels and energy security have increased interest in renewable energy sources. Biogas, generated from anaerobic digestion of organic wastes, has a relatively low cost and is considered to be a renewable energy carrier. There is an increasing interest in converting biogas to “green” transportation fuels. This fact sheet discusses the technologies that are curre...

Sulfur-containing compounds in transportation fuels are converted by combustion to SOx, which is a major source of acid rain and air pollution [1]. For environmental protection pur‐ poses, many countries have mandated a reduction in fuels sulfur level down to 10 ppm by 2009 [2,3], and with more and more stringent regulatory constraints, it is a trend to achieve little-to-no sulfur fuels in the ...
