I’ve always been shocked at the amount of food that is wasted and the huge environmental impact food production has. We grow food and transport it all over the world, often flying it thousands of miles and then transporting it by road for hundreds of miles only to throw half of it away because it is the wrong shape, colour or past it’s “best by” date. We eventually get the food to the school, restaurant, hospital or home, prepare it and then leave some of it on the plate. Next it goes into a bin to be collected by bin lorries that transport it miles to dump it into land fill sites where it decomposes to produce methane and carbon dioxide – more greenhouse gases – and because it gets mixed in with all the other rubbish it is of no use to anyone.
I believe that it is important for us and our children to understand where our food comes from and the real cost of producing it. Many schools are already growing food so that their pupils realise that peas and tomatoes come from plants and not tins or packets from supermarkets.
But it is also important to understand where our food waste goes and the impact it has on the environment. Some schools have started compost heaps to dispose of vegetable waste but this usually deals with a small amount of the food waste produced by a school.
A company called Ridan was a finalist in the Devon Environment Business Initiative (DEBI) awards for its Ridan Composter, a carbon negative device that can turn food waste into useful compost that can be used in the school grounds. There is also a cash saving in the money saved on disposal costs and the opportunity to teach young people how food waste can become a valuable resource.
The Resurgence article that introduced me to the Ridan composter tells of a school that installed a Ridan composter and then had an assembly about it in which the children sang ‘I’ve got a brand new Ridan Composter’ to the tune of the Wurzels classic song!
The Ridan website also includes more information about composting. If your school is interested in installing a composter you may be eligble for a grant from organisations like Biffa.
