Guessing again Adam?
So, say there are ~1000 kids in a secondary school and they produce
500 crisp packets a day (plus what they might each bring in from home / elsewhere), I'm sure they would soon have the minimum quantity of 5kg."5 kilograms = 1000 TerraCycle® points" "8 kilograms = 1,600 TerraCycle® points"
"1 TerraCycle® point is worth 1 penny."
So 8kg would yield them 1600 pennies or £16.
You can get a box of ~96 2B pencils off Amazon for £15.98 (free next day delivery with Prime).
And irrespective of what they actually get, it's pretty well all win.
The kids win when they eat the crisps (that they were going to do anyway, unhealthy or otherwise), we all benefit if the packets don't get burnt, go into landfill or blow around the countryside, Walkers win some PR and recoup some of the recycling costs when they sell the products they make from said recycled plastics and the schools / charities win with they get a bit of cashback.
What's to dislike?
