Thanks to the hydro fracking shale gas revolution, the US is currently leading the oil and gas production race, recently overtaking Saudi Arabia in this quest. However, this does not come without its pitfalls. Pollution – both of the atmosphere,...
If we want to use natural gas to limit greenhouse gas emissions associated with climate change, it would be most effective to use it to replace fuel-oil furnaces and coal-fired power stations to generate heat and electricity rather than using...
A gas blowout at a natural gas well in Aliso Canyon resulted in over 100,000 tons of methane being released into the atmosphere before the leaking well was plugged on the 11th of February, according to a study that was...
The circular economy takes recycling one step further, making it a more efficient method of resource use than single cycle recycling. Consumers, small business and larger corporations alike are increasingly moving towards more sustainable alternatives when making purchasing decisions —...
A recent landfill fire in Mumbai, India, which was clearly visible from space, highlights the impact that atmospheric emissions from such a fire can have on the environment and human health — in terms of both greenhouse gases and airborne...
One of the benefits of using livestock waste in the biogas production process is that, compared to waste used in municipal sewage digesters, it has a relatively uniform composition. Consequently, upsets are uncommon once the digestion process is underway and...
Methane Production Potential of Farm Waste The rate of methane production is typically expressed as the volume of gas produced (measured in cubic feet) per pound of organic solids (volatile solids) destroyed. Livestock manure typically consists of around 80% organic...
Lets face it, farm animals generate a ton of waste -- waste that could in fact be recycled to produce energy and fertilizer, offering a second stream of income to a struggling farming enterprize. In the following series of articles...
Leachate Collection Layer Regardless of whether a landfill has an engineered landfill liner system installed, leachate collection is still an important issue. If a bottom liner system is installed, it is usually covered with a protective layer of sand or...
