The specialty chemical maker Ingevity says it is exploring strategic alternatives for its industrial specialties business, including most of its pine-derived chemicals. Last year, Ingevity announced the closure of pine chemical plants in Arkansas and Louisiana; the company now says it is reviewing the fate of portions of a pine chemical plant in South Carolina. The firm, which was spun off the paper company MeadWestvaco in 2015, will instead focus on its polymer and performance material businesses.
