[1] Lumena mines the glauberite and associated class of minerals that is the raw ingredient used by the company to manufacture PPS and thenardite products including laxatives.

The Hong Kong listed company was suspended from trading by the exchange after Glaucus, a short seller investment research firm, published a report that alleged sales stated by the company were fraudulently inflated and its claim to have the most production capacity volume was misleading.

[6] Lumena is one of a handful of manufacturers of PPS, a plastic with several engineering applications, along with competitors including Solvay (which bought the PPS business from Chevron Philips), Chengdu Letian, DIC Corporation, Kureha, Fortron (a joint venture between Kureha and Ticona), Toray Industries, and Tosoh.

[7] The goal behind the acquisition was to build a vertically integrated company as one of the main feedstocks in producing PPS is thenardite.

[8] Procter & Gamble is a major buyer of powdered thenardite from the company, using it to make laundry detergent.
