Letter: Recycling threat

Published 3 July 1999

From Tom Tate, Imperial College

Your article on the Belgian food scare is particularly alarming, if I have
understood it correctly
(This Week, 12 June, p 4).
You state: “One theory is
that used transformer oil, rich in PCBs, was dumped in a public recycling
container for used frying oil. The batch would have made 1600 tonnes of feed,
enough to feed 16 million chickens for a day.”

So used cooking oil, collected from public recycling sites (which are largely
unsupervised, if British sites are anything to go by), is not, as I had always
assumed, used in manufacturing hydrocarbon-based materials, but is put straight
back into the food chain.

It sounds like a bad idea. Is this really the case?
