Cornwall Cullet was started in 1995 by John Lee, who at the time was in the double glazing industry and with the problem of getting rid of the waste glass (cullet). After reading an article in a trade magazine, he noticed that an advert from a waste glass recycling firm looking for people to supply them. After a few phone calls, he decided that he would start collecting and offering other companies in the same trade a service for recycling window glass.
