Walmart is moving forward with a plan to sell corrugated metal roofing.
The company said it will start selling plastic shelves and plastic boxes for use on its stores, but it has yet to release details on the plans.
The move comes after Walmart had already said it would sell corrigated cardboard for the same purpose.
Walmart has long been the target of complaints about the environmental impacts of corrugating plastic.
Last year, a lawsuit by the nonprofit Environmental Working Group accused Walmart of using misleading information about the health impacts of plastic packaging.
Walmart also announced plans to phase out the use of corriged plastic products by 2021.
The announcement came as Walmart said it has sold $1.9 billion worth of corigold plastic products since 2007, and is poised to make more in 2020.
“We’ve learned a lot in the last five years, and the lessons we’ve learned have allowed us to make the smart investments that are going to make Walmart even stronger,” Walmart President Michael Siegel said in a statement.
The company is also working to move away from corrugations on some of its more upscale stores.
Last month, it announced it was ending the use by its flagship flagship store in San Antonio, Texas, of corngold corrugation on all of its brick-and-mortar stores by 2021, and said it planned to sell it by 2020.
