WEST TERRE HAUTE, Ind. (AP): A Connecticut-based company is planning a $450 million project to convert a closed coal gasification plant in western Indiana into an ammonia fertilizer production facility.

The project announced Wednesday will be at the former SG Solutions coal gasification plant near West Terre Haute. Current owner Wabash Valley Power Association decided last year to shut it this spring.

The (Terre Haute) Tribune-Star reports Phibro LLC’s affiliate Phillip Brothers Fertilizer plans to use petroleum coke from Midwest refineries to produce ammonia. Company officials say the project has a mid-2018 completion target and the fertilizer plant could have about 100 jobs.

Phibro CEO Simon Greenshields says the plant will provide affordable fertilizer for farmers in the area and reduce the need for imported ammonia fertilizer.
