US: Lehigh Cement’s is preparing to co-process ‘raggertail’ at its Glens Falls plant in New York state. The state Department of Environmental Conservation (DEC) has prepared a draft air pollution permit for the unit. It is accepting public comments until late December 2018.
Raggertail is derived from non-recyclable ‘raggertail’ residuals processed by Frontier Fiber from Norampac and Greenpac recycled paper mills in Niagara Falls. It consists of approximately 60% plastic and 40% fibre (biomass). Emissions testing performed at the plant while burning the alternative fuel on a trial basis demonstrated that its use will not cause ambient impacts above State guideline concentrations. At present the cement plant’s kiln is powered by natural gas and coal.
