A Scottish startup is turning sawdust into replacements for petrochemicals, addressing global dependency concerns.
- The initiative aims to lessen reliance on fossil fuels by using forestry waste in the cosmetics, packaging, and pharmaceutical industries.
- Research indicates that the pharma industry emits more carbon than automotive sector, highlighting urgency.
- New ultrasound technology is central to transforming wood waste into usable compounds, specifically lignin.
- This approach could significantly boost Scotland’s economy while promoting environmental sustainability.
In an effort to replace petrochemical use, a group of Scottish researchers is developing a process to convert sawdust and woodchips into natural alternatives. This innovative method aims to address environmental challenges brought by the heavy reliance on petrochemical products in various industries, including cosmetics and pharmaceuticals.
Petrochemicals are prevalent in numerous everyday items, from medical products to make-up. However, their production significantly contributes to global emissions, with recent studies showing the pharmaceutical industry surpasses even the automotive sector in terms of pollution. Sonichem, a clean tech startup, hopes to change this with its promising technology.
The core of Sonichem’s breakthrough is a patented ultrasound process that effectively breaks down forestry by-products into natural chemical compounds. According to Sonichem’s chief chemist Andy West, lignin—a component found in wood and bark—is particularly promising for widespread industrial use: “Lignin is highly versatile and can be used in almost any setting.” This new method could revolutionise how we think about sustainable manufacturing.
Lignin traditionally acts as a natural adhesive in trees, making extraction challenging. However, Sonichem’s ultrasound technology could unveil new practical applications for this compound, reducing dependency on petrochemicals. This technological advance aligns with broader governmental goals to minimise fossil fuel reliance, presenting a step towards a net-zero future.
The onward strategy involves engaging with current manufacturers and the forestry sector to ensure a sustainable supply of the right types of trees. By utilising biomass from sawmills, there’s potential for significant economic growth within Scotland’s forestry sector, currently valued over £1 billion. Dr. Liz Fletcher from the Industrial Biotechnology Innovation Centre notes that this example of innovative eco-friendly business could transform low-value biomass into a vital resource.
This pioneering project not only exemplifies environmental responsibility but also offers economic opportunities through innovative use of natural resources.
