A landfill methane emissions rule implemented by the Trump administration that delayed action to limit methane emissions from landfills was scrapped earlier this month by a federal appeals court in Washington, D.C. Landfill methane emissions a potent greenhouse gas Landfills...
Scientists have developed a system for ranking toxins commonly found in landfills according to their quantity and level of toxicity, allowing landfill managers and environmental agencies to better manage the environmental threats posed by toxins in leachate. There are nearly...
By Adam Singfield An injection of corporate funding from business giants could boost the development of carbon capture and storage technologies with the purpose of sucking carbon dioxide from the atmosphere and storing it underground in a grand effort to...
Biogas can have impurities removed and upgraded to render it suitable for use as a vehicle fuel. This analysis examines the environmental and economic costs associated with cleaning, upgrading, and compressing RNG for use as compressed natural gas (CNG)...
Biogas can be cleaned to improve the quality, and once upgraded, it can be injected into a natural gas pipeline. In order for the raw biogas to meet quality standards required by pipeline operators contaminants such as sulfur, siloxane,...
A gas turbine engine (also known as a combustion turbine engine) operates on the Brayton Cycle, which is the same thermodynamic cycle that a microturbine engine operates on, but the capacity of a gas turbine engine is larger, ranging...
Burning off biogas produced as a byproduct of activities (e.g. on landfills) by flaring it rather than recovering the biogas for use as a source of energy is one way of getting rid of methane and volatile organic carbons...
Environmental & Economic Impacts of Biogas Combustion in Piston/Reciprocating Engines Reciprocating internal combustion engines, or piston engines, are used worldwide as a low-cost method of generating power. Reciprocating combustion engines have also been widely used to generate power from...
Biogas produced from the anaerobic digestion of organic waste offers a valuable source of renewable energy. Considering the abundance of organic waste produced by various human activities, this could provide a significant source of renewable energy that is completely sustainable...
