LIGNIN SEPARATION AND EPOXIDE-LIGNIN MANUFACTURING

Environmentally Friendly Polymer Replaces Petroleum-Based Materials

Petroleum is a versatile material, a key ingredient in thousands of everyday products, including the plastic found in products ranging from garbage and grocery bags to computers to cars to telephones and even furniture. Unfortunately, using petroleum-based chemicals has several environmental disadvantages. Most notably, the emissions from the manufacture of these products can release toxic by-products like formaldehyde, a suspected carcinogen, into the environment. Further, disposing of these petrochemical based products, which do not break down efficiently, has led to diminishing landfill space.

Benefits Replacing Petroleum Based Materials With Lignin Based Polymers

◆ Improves safety of workplace environment due to reduced exposure to formaldehyde
◆ Substitutes a renewable environmentally friendly resource for petroleum-derived resins
◆ Produces a lower-cost manufacturing resin with improved performance
◆ Lowers disposal costs for pulp mills and reduces the amount of black liquor burned, reducing air emissions and costs to comply with environmental laws and air emission ceilings

Applications

Resource recovery in pulp and paper industry, which produces resins for the automotive, foundry, plastics,construction, military, furniture,marine, and agricultural industries.

Capabilities

Able to treat black liquor from pulp mills to extract lignin, which is filtered and modified to create manufacturing resins that substitute for urea-formaldehyde, polyesterphenolic, and polyurethane resins.
