The tone of news stories about food waste shifted a week or so ago. For nearly a month, news outlets and bloggers seemed so overwhelmed with the size of the problem, that few bothered to dig deeper. But, those rehashed stories on the amount of food wasted in developed nations are now becoming more nuanced.
According to the USDA, the annual cost of food waste for an average family of four in the United States is $2,275.
My interested in waste management was piqued by an investigation onthe life cycle of our food waste once it has been collected. This story focuses on a community that already requires food waste to be separated from other waste. For those who need to see the magnitude of food waste we generate each week, call your local waste management centre. Many waste and water treatment plants offer tours for the public.
Another report claims that LED lighting might slow food decay in grocery stores and save about 300,000 tonnes of food waste, simply because LED light do not burn as hot as incandescent lights. (Of course, the study was funded by Sedna LED, so more research is needed, but it may be a way to work with local grocery stores to help find new ways to reduce their costs and reduce food waste.)
Massachusetts is leading the way in the United States, with two approaches to reduce the amount of food that ends up in land fills. The state now requires businesses in the food industry to compost their organic waste, the goal is to expand this requirement to every home in the state.
But there is a more interesting approach to managing food waste that might be even more efficient. A province in Korea has implemented a mandatory “pay-as-you-throw” system charges households for throwing food in the bin. What appeals to me about this approach is that economic cost of wasting food becomes more transparent and big wasters pay more for being wasteful than those who are frugal.
And, finally, it looks like the plastics industry is jumping into the food waste debate and looking for ways to help reduce food waste with better packaging. This report has me wondering about other landfill issues, but we work hard to reduce packaging waste at home too, so I may be a bit biased.
