Upon arrival at the mill, the wood logs are chopped down into small chips and chemically processed to separate pulp from lignin. This pulp is then bleached, dried, and baled for transport to the client. Pulp represents our present capital and lignin is a renewable energy and one of the paths to new businesses.
