Bulgarian May Day-Varna foundation (name as given by the source) is to launch a pilot project in Russe, northeastern Bulgaria, where offices will use chiefly recycled paper over a period of nine months, it was reported on February 4, 2003. In the capital Sofia alone a total of 12.5 million sheets of paper are being used every month, experts said. Some 3,125 trees have to be felled in order to provide this much paper, which will upset the ecological balance, foundation experts said. No further details were available.
