RENEWABLE PRODUCTS FROM
FOREST INDUSTRY RESIDUES
About
Carbon is a key building block in almost everything we have around us. To maintain our way of living, we need to secure sustainable carbon sources for the future. The forest industry has a long history of working with carbon, in the form of wood, where most of it ends up in everyday products like paper, carton board, textiles, hygiene articles and sawn products. There is however a large, carbon rich resource coming from woody biomass - lignin - that is waiting to be unlocked for higher value purposes. Pulp mills have been finetuned ever since paper making was first invented into a well-tuned and mature process industry. Extracting the lignin without disturbing the chemical balance of the mill requires great finess. SunCarbon is doing exactly that - producing valuable lignin, or “Carbon Green” as we call it, while returning the cooking chemicals to the mill.
We’re hiring!
We’re currently looking for a dedicated chemical engineer to take part in our journey towards a full-scale lignin production process. If you’re interested, reach out to us for a chat to learn more! Full job ad (in Swedish) can be found on LinkedIn here.
Technology
Fundamental understanding
Lignin is a true wonder of nature - an extremely complex polymer, essential to plant life, but with properties that has been challenging researchers for decades. Understanding how lignin interacts with water and oil media during variations in pH, temperature and pressure is key to develop a cost efficient and robust process.
The solution of SunCarbon is based on years of experience working with lignin in the lab. We know what works, and what does not.
Technical solutions
To make actual impact, the results of the lab scale trials needs to be adapted to industrial conditions. We work directly plugged into mill operations to make sure that what we have developed works where it’s supposed to. We have challenged ourselves to integrate our concept into the Kraft process for retrieving lignin. The lignin in the kraft process comes dissolved in the black liquor, and the handling of it determines the final product. The key for any success is the integration - we have been extensively working on how to accommodate our process into the mill chemical-, energy and heat balances while extracting the lignin-based product Carbon Green.
Legacy
Lars Stigsson (1953-2022) founded SunCarbon with a clear vision of contributing to a better world by using chemistry. His wisdom and lively enthusiasm are greatly missed. Following his path of developing new processes towards new environmentally-friendly products remains with us.
