A Nova Scotia company says it could turn hundreds of millions of litres of polluted sludge from Boat Harbour into a non-toxic construction material, offering an alternative to the current plan to permanently store the dredged sediment in a massive tank on site.
Boat Harbour was once a tidal estuary, but for more than 50 years it acted as a receptacle for industrial waste from the nearby and now shuttered Abercrombie, N.S., pulp and paper mill currently owned by Northern Pulp.
