The University of Bath’s Department of Chemistry and Institute for Sustainability have made a groundbreaking discovery in the field of pharmaceutical production. By utilizing a compound found in pine trees and waste from the paper industry, scientists have found a sustainable way to produce two widely used painkillers, paracetamol and ibuprofen. This innovative approach addresses the sustainability challenge posed by the reliance on crude oil-derived chemical precursors for manufacturing pharmaceuticals.
The research team from the University of Bath has developed a method to produce pharmaceutical precursors from biorenewable β-pinene, which is present in turpentine, a waste by-product generated by the paper industry. With an annual production exceeding 350,000 tons, β-pinene has the potential to revolutionize the pharmaceutical industry. By converting β-pinene into paracetamol and ibuprofen, which are produced on a massive scale, the researchers have showcased the viability of this sustainable approach.
The groundbreaking discovery goes beyond just painkillers. The scientists have also synthesized several other precursor chemicals from turpentine, including 4-HAP (4-hydroxyacetophenone), which serves as the precursor for drugs like beta-blockers and the asthma inhaler drug, salbutamol. These chemicals are not only vital for pharmaceuticals but also find applications in perfumes and cleaning products.
Dr. Josh Tibbetts, a Research Associate in the University’s Department of Chemistry, highlights the inherent unsustainability of using oil to manufacture pharmaceuticals. This reliance not only contributes to rising CO2 emissions but also introduces price volatility due to geopolitical factors affecting oil reserves. With their sustainable “biorefinery” approach, the research team envisions a future where the extraction of oil from the ground is replaced by a bio-based model.
The turpentine-based biorefinery model developed by the scientists utilizes waste chemical by-products from the paper industry to produce a wide range of valuable and sustainable chemicals. This includes the production of not just painkillers, but also perfumes and other commodities. The researchers employ continuous flow reactors, as opposed to traditional batch production methods, allowing for uninterrupted and scalable production.
While the current process may be slightly more costly compared to using oil-based feedstocks, there is a potential willingness among consumers to pay a slightly higher price for pharmaceuticals that are both sustainable and plant-derived. This discovery marks a significant step towards a more environmentally friendly and economically stable future in the pharmaceutical industry.
The scientists from the University of Bath have discovered a sustainable way to produce common painkillers, paracetamol, and ibuprofen, by leveraging a compound found in pine trees and waste from the paper industry. This breakthrough extends beyond painkillers, as it allows for the production of various pharmaceutical precursors used in beta-blockers and asthma inhalers. By challenging the reliance on crude oil in pharmaceutical production, this innovative approach paves the way for a more sustainable and cost-effective industry. With their bio-refinery model, the researchers demonstrate the potential of waste products to drive positive change in pharmaceutical production and help create a greener future.
