Tristram Stuart is a visionary who elucidated his viewers on the issue of food waste in his TED talks in May of 2012. The experience that opened his eyes to this tragedy occurred when he decided to purchase swine to produce pork for profit. He fed his pigs the unwanted food from his school bakery and other places. He noticed that the food was fit for human consumption.
because of the lack of empherical data on national and global food waste, Tristram modeled it himself. It was concluded that ( if you take into account the food given to livestock) European and North American countries produce 3 to 4 times surplus food than it needs. This is a colossal waste of food.
Using biscuits he found in the garbage of a local supermarket, Tristram models where our food actually goes. Out of 9 biscuits
- 1 is thrown out in the fields
- 3 are fed to livestock- 2 are turned into feces and heat, and 1 is left
- 2 we throw in the garbage
- We are left with 4 biscuits, we discard more food than we eat.
Because food is not “supermarket quality” the majority of it is thrown out or fed to pigs and other animals. There is inevitably going to be some level of food waste, this is unavoidable, however such waste can be used in raising pigs for pork production. This reduces CO2 emissions much more efficiently than using the wasted food to produce energy.
