CMPC is seeking solutions to help fight the blue staining in wood caused by the Ceratocystis Pilífera fungus.


Innovation Challenge

Low Water, Blue Stain-Free Wood Challenge

CMPC, one of the biggest worldwide pulp and paper companies, is seeking solutions to help fight the blue staining in wood caused by the Ceratocystis Pilífera fungus. This stain is currently prevented with high water use throughout the processing stage.

The Opportunity

One of the main goals of CMPC's 2030 strategy is to reduce the consumption of water in its operations. 

Currently, one of the operations with significant water usage is the prevention of the blue stain caused by the fungus Ceratocystis Pilífera in radiata pine logs stored in their yards during the summer months. 

The only way to avoid the appearance of the fungus is by watering the logs as once the blue stain sets in, there is no way to get rid of it and it will appear in the end product. 

CMPC is searching for alternatives to prevent the appearance and growth of this blue stain fungus by avoiding or significantly reducing the use of water.

The prize will be co-creating a pilot proposal with CMPC to potentially implement your technology in their yards. If your technology has not been tested with this fungus, CMPC will test your technology in their labs, and if it's successful, will co-create a pilot proposal with your team.

The Partner

CMPC produces and commercializes products based on pulp, paper, wood, and tissue. The company was born in 1920 with the production of papers and cardboards, and today commercializes its products through its three main businesses: Pulp, Biopackaging and Softys, reaching more than 26,700 direct clients around the world.
