Nicknamed Chester by students, the award-winning digester has been gobbling up food scraps, leftovers and expired ingredients.
“We grow food, pick it, process it, transport it to stores, purchase it, transport it home, store it, cook it and then toss it out? That’s just crazy.”
What will happen when these ancient, ice-bound viruses thaw out?

The president and whomever he chooses to serve as his Interior secretary will have broad authority to decide what kind of energy development should take place on land owned by the federal government. On this question, Biden has been clear — he has said he would not issue new leases for fracking on federal lands.
Burger King is staging an intervention with its cows. By tweaking their diet, it said it believes it can reduce a cow's daily methane emissions by about 33%.
Biofuel -- much of which is burned in garbage trucks and other heavy equipment -- not only offsets the use of fossil fuels, it also keeps methane -- a far more potent greenhouse gas than carbon dioxide -- from escaping into the atmosphere.
Two energy scholars who have studied the extent of methane leaks in the oil and gas industry explain what rescinding methane emissions regulat…
The U.S. natural gas infrastructure includes a million miles of pipes and millions of valves, fittings, tanks, compressors and other components that operate 24 hours per day, 7 days per week, to deliver natural gas to your home. Natural gas can travel over 1,000 miles from the well to end use. During that long journey, gas has many opportunities to escape into the atmosphere. This includes unwanted leaks from faulty components as well as intentional venting of gas from devices that use the high-pressure gas to open and close valves.
Because the natural gas infrastructure is so vast, it is not possible to measure every leak from every faulty valve or fitting. Indeed, we don’t even have accurate estimates of the total number of valves and fittings. The best way to estimate the total amount of methane emissions from the natural gas infrastructure is to perform as many measurements as possible from as many different types of components as possible. The reason that one has to perform hundreds or even thousands of measurements from each type of equipment is so that you can capture the high-emitting sources (the so-called super-emitters), which are low in number but their emissions are so high that they can account for 50% to 80% of the total emissions.
The Obama-era regulations were put in place in 2016 to set emissions limits for methane from a variety of sources in the oil and gas industry. The 2016 regulations built upon previous regulations put in place in 2012 for emissions of volatile organic hydrocarbons (VOCs), which are nonmethane hydrocarbon gases produced by oil and gas operations. The companies that had installed controls for VOC emissions sources were not required to install any new controls because reduction in VOC emissions also reduce methane emissions.
Methane is a highly potent greenhouse gas, with more than 80 times the climate warming impact of carbon dioxide over the first 20 years after it is released. Studies show that if methane leaked at a rate of greater than 3%, there would be no immediate climate benefits from retiring coal-fired power plants in favor of natural gas power plants. The good news is that a 2.3% leak rate suggests that natural gas power plants are slightly more beneficial to the climate in comparison to coal-fired power plants. However, the results of our studies also showed that power plants could show more substantial benefit to the climate if the industry reduced the total methane leakage rate to 1%, which many of our industry partners believe to be achievable.
The EPA estimates that the proposed new amendments would save the oil and gas industry $17 to $19 million per year. While this may sound like a lot of money, it pales in comparison to the economic value to be gained by minimizing leakage. We estimate that reducing methane emissions from 2.3% to 1% would result in an annual revenue of over a half billion dollars per year, which is more than 30 times the estimated savings from rolling back the regulations. Many oil and gas companies recognize this fact, and they also recognize that regulations are needed to ensure that all companies are held to the same standard.
I am pleased to read that some, though not all, of the oil and gas companies disagree with our president’s decision to roll back the regulatio…
