Due to the color, toxicity, and biological and chemical oxygen demand, lignin and other phenolic compounds are unwanted substances in effluents. But these compounds are often difficult and expensive to remove from the effluents.
Enzymes offer a simple solution for addressing lignin in effluent. Enzymes oxidize lignin and phenolic compounds to enable and promote separation from effluents and increase capacity. Moreover, enzymes can modify the residual lignin in unbleached pulp to improve the physical and mechanical properties of paper and board and the runnability of the paper machine.
Enzymes are a biodegradable alternative to petroleum-based and/or expensive strengthening agents and effluent management additives.
