Sonichem, a clean tech startup in Scotland, is pioneering a method to replace petrochemicals with natural compounds from sawdust.
- The company aims to open its first commercial plant by 2027, processing 15,000 tonnes of forestry material annually.
- Industries like cosmetics and pharmaceuticals heavily rely on petrochemicals, which contribute significantly to global emissions.
- Sonichem’s ultrasound process efficiently extracts lignin, a versatile natural polymer, providing an alternative to petrochemical compounds.
- The initiative is supported by various studies and collaborations, highlighting its potential role in achieving environmental sustainability.
A pioneering venture in Scotland, Sonichem is set on a path to revolutionize the reliance on petrochemicals by utilizing sawdust and woodchips. This groundbreaking approach aims to convert forestry waste into viable substitutes for chemicals derived from fossil fuels. The plan is ambitious, with Sonichem targeting the year 2027 to commence operations at a commercial facility designed to handle 15,000 tonnes of forestry material annually. This effort aligns with the broader governmental objectives to reduce fossil fuel dependency.
The cosmetics, packaging, and pharmaceutical sectors are known for their substantial use of petrochemicals. These industries contribute significantly to global emissions, with studies indicating that the pharmaceutical sector alone emits more carbon dioxide than the automotive industry. Sonichem’s innovative use of its patented ultrasound process aims to change this narrative by breaking down forestry co-products into natural, petrochemical substitutes.
Chief chemist Andy West highlights the versatility of lignin, a key component derived from wood. Lignin’s potential application as an alternative in various fields is largely due to its properties as a natural polymer. However, extraction has historically been a challenge as lignin acts as a structural ‘glue’ in trees. Sonichem’s advanced technology now offers the best chance yet to harness lignin’s properties effectively.
The ongoing development involves collaboration with manufacturers already using resin and the forestry sector to ensure sustainable supply chains. Strategic forestry management is crucial, as the right types and numbers of trees need to be planted to support future production demands.
Dr. Liz Fletcher from the Industrial Biotechnology Innovation Centre underscores the economic importance of Scotland’s forestry sector, which contributes over £1 billion to the economy. She sees Sonichem’s initiative as a catalyst for growth, turning biomass from sawmills into higher-value applications, beyond its traditional low-value uses.
Sonichem’s innovative approach to using sawdust as a replacement for petrochemicals presents a promising step towards environmental sustainability and economic growth.
