I suppose there is a potential of added value ie providing a boat of malting barley from one source may gain a £1 or two more per ton which should pay for the overheads?
does it ever actually happen though ? do central store users get more for their grain over an above the cost of the storage ?
its like these colour sorters - fixing a niche problem that didn't exist but a great thing to get a big grant for despite the economics of them simply not adding up as far as I can tell
