Canada: Lehigh Cement has initiated the administrative process to begin the use of alternative fuels (AF) in cement production at its Picton cement plant in Ontario. Under the company’s plans, the plant will substitute 200t/day of AF for coal and petcoke at the plant. Possible AF sources include excess seed from farm feed production in Ontario. The Picton cement plant previously reduced its CO₂ emissions per tonne of cement by 20% through assorted sustainability initiatives.

Picton plant manager Carsten Schraeder said that the move will support Canada’s 2030 emission reduction plan, and also take pressure off landfill sites.

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.

Canada: The Metro Vancouver government body is considering sending its refuse as refuse derived fuel (RDF) pellets to the Lehigh Cement plant in Delta. The scheme is one of three new options the body is considering to manage its waste including incinerating it to produce electricity or gasification, according to local media.

"There's no electricity produced, but it would be a benefit because it would result in no increased air emissions. The others (mass burn and gasification) would have new emissions," said Sarah Wellman, project manager of Metro Vancouver's waste-to-energy project, in relation to the cement plant option.

Metro Vancouver is waiting to hear from the provincial government on how to proceed. The area currently generates electricity from the Covanta Burnaby Renewable Energy incineration plant.
