Vertus Technologies, a subsidiary of London-based Nviro Cleantech, has signed a 25-year contract with Cincinnati Bulk Terminals to install and operate a plant along the Ohio River.

The company says the facility will remove pollutants such as sulfur and mercury from coal before it is burned, and that could increase markets for Ohio coal. The project will cost $3 million to $5 million and will be able to process 100,000 tons of coal a year.
