” Until recently, food and other organic waste like this made up a quarter of our trash. Estimate gas and electric costs Massachusetts officials want to cut that in half by 2020. Cost of gas fireplace insert So, they’ve enacted a law that prohibits throwing away more than a ton of food each week.

Gas cost trip calculator While composting is sometimes compared to recycling for food, anaerobic digestion is the food equivalent of waste-to-energy. Estimate gas cost for trip Microbes break down food in the absence of air and produce bio-gas that can be burned to make electricity. Road trip gas cost calculator That’s what Stop and Shop chose.

“Stop and Shop’s goal is to be landfill-free by 2020, and we’re eighty eight percent of the way there,” says Tracey. Cost of a gas furnace “This is just the icing on the cake for us.

How to calculate fuel cost Inside, microbes are sucking up that food waste milkshake and spewing out methane gas. “So, this is the 1.2 million gallon reactor, the actual digester. The cost of gastric bypass surgery The biogas is rising to the top, and we’re pulling a vacuum on it and collecting that gas. Gas furnace cost calculator That’s then going into our generator – an internal combustion engine – where we’re burning the biogas.” There are eleven anaerobic digesters in Massachusetts producing electricity. Approximate gas cost for trip About half of those – including Stop and Shop – use the energy on-site, while the other half earn credit for the electricity they feed into the grid.

Cost of gas per gallon We fill up maybe two of those per week.

Miles to gas cost calculator And that was the first official training I had,” says Ryther.

Cost of gas hot water heater “More recently, the US composting council had a compost facility operators training course. Cost of gas boiler replacement And, again, that course was aimed at large scale facility operators.

Calculate cost of gas The other, Sandwich-based Watts Family Farms, works primarily with grocery stores on Cape Cod and the South Shore.

“So what we do is we dump it off the truck,” explains Ryther. Cost of gas for road trip “We put it into the wire, and then add the brown materials, which are the leaves, horse manure, wood chips, and cardboard.

” For composting to work, nitrogen-rich “greens” like food have to be mixed with carbon-rich “browns” like leaves and manure. Cost of gas today Ryther gets paid to take food waste, but accepts browns free of charge.

Cost of gas trip calculator She has three part-time employees and pays a bobcat operator to come in and turn the piles so they get the air they need. “The smelly days are the ones when you turn it, so we like to do it early in the morning, before the wind kicks up. How to calculate fuel cost per km We make sure there’s not a wedding going on,” says Ryther with a laugh.

Compost with Me is something of an experiment. Cost of gas in canada We know composting works biologically, the question is – can a small operator make a living at it. “Working on that,” says Ryther.

Figuring gas cost for trip “I think so, as long as an operator can make money from the collection of the food scrap materials, process it at a fairly low cost, and then sell the product at the end.” Both composting and anaerobic digestion keep uneaten food out of landfills and turn it into something useful. Average cost of a gallon of gas And there may even be a silver lining to the economic challenges they face. Gas cost calculator trip Institutions often find their best option is simply to reduce the amount of food they need to dispose of in the first place.
