Subject: [Biofuel] Half of US food goes to waste
... and half the energy use too?

Half of US food goes to waste
25/11/2004 - As the US celebrates Thanksgiving, a new study reveals that
almost half the food in the country goes to waste - a statistic that
should alarm an industry that is struggling to achieve greater efficiency
in order to salvage profits.
The new study, from the University of Arizona (UA) in Tucson, indicates
that a shocking forty to fifty per cent of all food ready for harvest
never gets eaten.
Timothy Jones, an anthropologist at the UA Bureau of Applied Research in
Anthropology, has spent the last 10 years measuring food loss, including
the last eight under a grant from the US department of agriculture (USDA).
Jones started examining practices in farms and orchards, before going onto
food production, retail, consumption and waste disposal.
What he found was that not only is edible food discarded that could feed
people who need it, but the rate of loss, even partially corrected, could
save US consumers and manufacturers tens of billions of dollars each year.
Jones says these losses also can be framed in terms of environmental
degradation and national security.
Jones' research evolved from and builds on earlier work done at the
University of Arizona. Archaeologists there began measuring garbage in the
1970s to see what was being thrown away and discovered that people were
not fully aware of what they were using and discarding.
Those earlier studies evolved into more sophisticated research using
contemporary archaeology and ethnography to understand not only the path
food travels from farms and orchards to landfills, but also the culture
and psychology behind the process.
The fact that the US is a wasteful nation is not necessarily news, of
course. The country has long has been chastised for its wilful consumption
of the world's resources, and many aspects of the country's culture
encapsulate what environmentalists disparagingly refer to as today's
throw-away society.
Similarly, researchers have known for years about the volumes of food
Americans toss into the trash. But only recently, though, has that been
quantified as a percentage of what is produced, and the UA statistics are
the first tangible proof that US food production is frighteningly
wasteful.
A certain amount of waste in the food stream cannot be helped of course.
Little can be done, for instance, about weather and crop deterioration.
The apple industry, for instance, loses on average about 12 per cent of
its crop on the way to market.
Apples in the US are harvested over a two-month period and then stored and
sold year-round. People in the apple business use aggressive methods to
maintain their crop, with fresh apples hitting the supermarkets on a
regular basis and marginal ones sent to be made into applesauce and other
products.
The goal of apple growers is to provide a nutritious product, all year
long, at fairly constant prices. Jones says they've adopted a conservative
business plan that forgoes the boom-and-bust cycles that other fruit and
vegetable growers aim for and opts instead for a steady income stream.
But Jones argues that fresh fruit and vegetable growers, in contrast,
often behave like riverboat gamblers. They will take a risk on the
commodity markets if they think it will help them make a financial
killing. A bad bet often means an entire crop is left in the field to be
ploughed under.
Jones' research also shows that by measuring how much food is actually
being brought into households, a clearer picture of that end of the food
stream is beginning to emerge.
On average, households waste 14 per cent of their food purchases. Fifteen
per cent of that includes products still within their expiration date but
never opened. Jones estimates an average family of four currently tosses
out $590 per year, just in meat, fruits, vegetables and grain products.
Jones says that consumers better need to understand that many kinds of
food can be refrigerated or frozen and eaten later. Nationwide, he says,
household food waste alone adds up to $43 billion, making it a serious
economic problem.
Cutting food waste would also go a long way toward reducing serious
environmental problems. Jones estimates that reducing food waste by half
could reduce adverse environmental impacts by 25 per cent through reduced
landfill use, soil depletion and applications of fertilisers, pesticides
and herbicides.
Consumers and retailers are also of course responsible for minimising food
waste, but it is manufacturers, who are being squeezed by high raw
material prices and low retail costs, that stand to
