CEO John Casella, of locally based Casella Waste Systems, told Waste Dive in April he thought this material might even need to be dropped from recycling programs if the situation didn't turn around. Casella operates the largest MRFs in Vermont as well as others throughout the Northeast. In May, during the company's quarterly earnings call, Casella said mixed paper prices were down by 90% YoY and he expected the situation could get worse if other developing Southeast Asian markets became saturated.
