so, this is a modern day mini churn. it can hold ten litres of milk which is the equivalent of five of these plastic cartons. but the important thing is that this is made stainless steel, so could last a lifetime, whereas the plastic bottles are only used once. once delivered to coffee shops, the churns are housed in bespoke fridges. milk is dispensed directly intojugs, programmed to measure exactly the right amount for different drinks. we have just been using it for at least a couple of weeks now and it saves so much time and effort. we are a busy cafe and we were using quite a lot of the milk bottles so you can imagine, the bins were up and up and up. we can prove a concept, i we can show that it can work, but then we can share it with bigger business around sheffield and around the country. every year, the university of sheffield cafes dispose of 87,000 plastic cartons of milk. it was time to find an environmentally friendly alternative.
