Vale of Glamorgan Foodshare gives members a means of offering excess perishable or nonperishable unexpired / unspoiled food items that might otherwise go to waste.
The principle is very similar to RealCycle or FreeSharing and members can offer items such as excess items from government programs (infant formula, milk, etc), excess items from your cabinets and pantries, seeds, plants, fruit before it rots on the tree, excess veggies from the farm or garden, canned goods, emergency survival stock, pet foods, and so on.
We all have that tin of unwanted soup or peaches in the back of the cupboard, if you don't want it, then offer it, someone may well have it.
This is new for the UK, and will be interesting to see how it goes.
