If a landfill operator has invested in a landfill gas operation, that might be the most economically feasible place to send organic waste.

Most of us don’t think of food waste as a cause of global warming, but it’s a significant one that also contributes to world hunger.
Cleaning up wastewater from coffee processing not only prevents water pollution, but also creates biogas that would otherwise be emitted as methane.
Anaerobic digestion – extracting methane from organic wastes – doesn’t get the love of, say, solar and wind: it’s not nearly as sexy, and definitely more smelly. But it’s also a renewable energy technology with plenty of available feedstock: all of that food waste we discuss regularly could go towards the creation of biogas.
The phrase “food to fuel” often refers to production of corn-based ethanol or soy-based biodiesel… not exactly most efficient use of these commodities. But there are situations when food to fuel represents a smart use of resources: when that food will go to a landfill. While the capture of landfill gas has become more prevalent, why spend the money and other resources shipping it there? Why not just direct food waste to energy production?
Ideas are where all innovation begins. The environment is not only becoming a big part of the public dialogue, it is also fueling research, education, and business. The green job sector is amongst the fastest growing in a fairly unstable and stagnant economy.
While carbon dioxide receives most of the attention in the debate over greenhouse gas emissions, climate scientists warn that methane is about 30 times more potent than CO2 in terms of contributing to a warmer climate. You’ve likely already seen concerns expressed about methane emissions from geological sources, as well as from cattle and other […]
A landfill gas-to-energy plant in Conestoga, Pennsylvania. When it comes to corporations fighting climate change, landfill owners don’t necessarily leap to mind. But in Michigan, the landfill industry is working to repeal a 19-year-old ban on the disposal of grass clippings and tree trimmings in dumps — on the grounds that the yard waste, mixed […]
[social_buttons] I’m probably going to irritate some people with this post. I apologize in advance because that is not at all my intention. For those readers that don’t think climate change is a real problem, I respect the fact that there is uncertainty in that science, but if the majority position of climate scientists is true, the […]
[social_buttons] When thinking about “carbon footprints” it helps to have real numbers to put things in perspective. The EPA estimates that for the US, agriculture represents about 8% of total human-related greenhouse gas emissions. The following is a list with a little of the detail of what makes up the footprint of an acre of […]
[social_buttons] My earlier blog about greenhouse gas emissions from composting generated a lot of good discussion so I am writing to respond. Yes, composting is certainly better than some outcomes like food scraps going into a garbage dump which does not do anything to capture the methane Yes, an anaerobic digester would be a very […]
Composting is a really green thing to do, right? I’ve always thought so since my Grandfather taught me to do it in the early sixties. Large-scale composting is getting to be quite the rage. The City of San Francisco attracted a great deal of attention with it’s mandatory food scrap recycling program and lots of local […]
With Congress deep in debate over legislation aimed at the prevention of global warming, and skeptics ramping up their rhetoric, it seemed like a good time to take a step back to some basics — more accurate information is critical here. Step one in figuring in out how we can help in the battle against […]
