Snippets – Waste Not Want Not

1
Today, I want to share a few not-quite-so-recent stories related to waste that have been on my mind lately.
Via the New York Times, a food industry alliance is planning a three-year initiative to reduce the tremendous amount of food that Americans still throw in the garbage even as they grow somewhat more conscientious about recycling paper and yard trimmings. … A substantial portion of food is thrown away while still fully edible because of cosmetic blemishes or overstocking. … According to the most recent available statistics, more than 30 million tons of food was dumped in landfills in 2009, making food by far the most abundant material there by weight, the federal Environmental Protection Agency says.
From NPR comes a story about how all that wasted food contributes to climate change. A company called CleanMetrics gathered USDA’s estimates of food loss from retail and consumers for 2009. And when the company’s founder, Kumar Venkat, fed the data into his software he found that food waste is responsible for 135 million tons of greenhouse gases every year, or about 1.5 percent of all emissions ,,,  “If you compare beef to tomatoes, beef has a much higher footprint,” says Venkat. “So if you’re going to reduce waste, you need to prioritize.”
Via Bloomberg, a story about Bank of America selecting some its most decrepit, derelict homes in Cleveland, Detroit, and Chicago and paying up to $7,500 to local agencies toward demolition costs. “There is way too much supply,” said Gus Frangos, president of the Cleveland-based Cuyahoga County Land Reutilization Corp., which works with lenders, government officials and homeowners to salvage vacant homes. “The best thing we can do to stabilize the market is to get the garbage off.”
From the New York Times –  Across western North Dakota, hundreds of fires burn as companies rushing to extract oil from the Bakken shale field treat the gas as waste and simply burn it. … Every day, more than 100 million cubic feet of natural gas is flared this way — enough energy to heat half a million homes for a day. The flared gas also spews at least two million tons of carbon dioxide into the atmosphere every year, as much as 384,000 cars or a medium-size coal-fired power plant would emit.
And again from NPR, some insight into why cleaned wastewater stays dirty in our minds. … “It’s a very broad feature of human thinking,” Nemeroff explains. “Everywhere we look, you can see contagion thinking.” … The conclusion? “It is quite difficult to get the cognitive sewage out of the water, even after the real sewage is gone,” Nemeroff says.

Links – Water and Energy

Alex Wilson, of BuildingGreen, has written two blogs posts recently that I think will be of interest to Zero Resource readers…I’ve posted snippets, but I recommend reading the entire original posts.

Saving Energy by Conserving Water

Averaged statewide , roughly 5% of California’s electricity is used for moving and treating water and wastewater. (The oft-quoted figure of 19% includes water heating and other things we do with water in homes, businesses, and farms.) But these figures vary widely in different parts of the state. A 2005 report from the California Energy Commission found supply and conveyance of water to range in intensity from 0 to 16,000 kilowatt-hours per million gallons (kWh/MG), while filtration and treatment varied from 100 to 1,500 kWh/MG, distribution varied from 700 to 1,200 kWh/MG, and wastewater collection and treatment varied from 1,100 to 5,000 kWh/MG. Not surprisingly, average totals are far higher in southern California (12,700 kWh/MG) than in northern California (3,950 kWh/MG).

Saving Water by Conserving Energy

By weighting thermoelectric and hydroelectric power generation sources, the NREL report calculated an average water-intensity of electricity in the U.S. to be 2.0 gal/kWh. So if you use 500 kWh per month, that’s requiring, on average, 1,000 gallons of water.
