Do you Know Producing the food we Throw Away generates more greenhouse gases (GHGs) than most entire countries do ?
More than a third of all of the food that's produced on our planet never reaches a table. It's either spoiled in transit or thrown out by consumers in wealthier countries, who typically buy too much and toss the excess. This works out to roughly 1.3 billion tons of food, worth nearly $1 trillion at retail prices.
Aside from the social, economic, and moral implications of that waste—in a world where an estimated 805 million people go to bed hungry each night—the environmental cost of producing all that food, for nothing, is staggering.
The water wastage alone would be the equivalent of the entire annual flow of the Volga—Europe's largest river—according to a UN report. The energy that goes into the production, harvesting, transporting, and packaging of that wasted food, meanwhile, generates more than 3.3 billion metric tons of carbon dioxide. If food waste were a country, it would be the world's third largest emitter of greenhouse gases, behind the U.S. and China.
What are the solutions?
ohn Mandyck, the chief sustainability officer of United Technologies, a U.S.-based engineering and refrigerated transport firm, says that food waste can be mitigated by improving the "cold chain," which comprises refrigerated transport and storage facilities.
However, we can't take today's sophisticated refrigerated truck-trailer systems available in the U.S. and Europe and expect they can be immediately adopted in emerging countries. In many cases, the roads in these countries can't accommodate large truck systems, the technical skill is not yet present to support the systems, and the economy can't yet afford the systems. So we have to scale the technology to the local needs—smaller systems, fewer features, more affordable...
