Pulp and paper experts in Sweden are set on creating new bio-based products from the waste generated in pulp and paper mills.
Pulp and Paper Waste Doesn’t Have to Go to Waste
Raw materials used in many industries are often expensive and in high demand. By using the by-product of pulp and paper processes, industries open themselves up to more sustainable and affordable production of all kinds of products.
Karin Willquist, Project Manager and researcher at RISE, Research Institutes of Sweden, says that “Industries can compete for the same raw materials, but here we start with something that no one really wants. What was previously a by-product waste from a purification problem is now becoming a cascaded resource.”
The waste residues from pulp and paper can be converted into fossil-free bioplastics, bio-hydrogen gas and fish feed. Researchers and practitioners have been working to integrate economic flows and materials in pulp and paper mills with the fish farming industry to create a strong business partnership. The main goal is to create an environment where the market for bio-based products and services can thrive.
A One-of-a-Kind Project
This Swedish project is unlike any other project in sustainable use of waste and by-products. For one, it couples three processes into a single system. It also allows pulp and paper mills to continue their normal processes, methods, and business while also partaking in renewable resource production.
