Clean Harbors said it intends to use the net proceeds to finance the purchase price of its acquisition of environmental and waste management services provider EnviroServe. The remainder of the net proceeds will be used to repay the borrowings under its revolving credit facility that were incurred to partially finance the purchase price of its acquisition of ES&H, the company said. If either acquisition is not completed, the company said it intends to use the remaining net proceeds for general corporate purposes.
