A 2019 study by researchers found that, contrary to popular belief, the pharmaceutical industry produces more carbon dioxide equivalents per million dollars than the automotive sector. Despite its relatively small size in comparison to other industries, the pharmaceutical sector still has an urgent need to reduce its carbon emission levels.
Scientists at the University of Bath in the United Kingdom have proposed a solution to this problem. They’ve devised a revolutionary technique that makes use of a-pinene, a component of turpentine, in the production of medications like paracetamol and ibuprofen.
A great breakthrough by researchers
Chemical precursors produced from crude oil are typically used by pharmaceutical companies to produce these over-the-counter pain relievers. Turpentine, on the other hand, is produced in excess of 350,000 metric tons annually as a byproduct of the paper industry and is thus readily available. Scientists have proven that turpentine can be used to synthesize 4-HAP, a precursor of beta-blockers, salbutamol, and other common cleaning chemicals.
Since turpentine is unaffected by the geopolitical forces that create swings in energy and oil prices, this novel ‘bio-refinery’ technology may help stabilize medicine prices for customers.
Drugs made from turpentine are currently more expensive than crude oil to produce. The researchers speculate that some patients would be prepared to pay a somewhat higher price for more environmentally friendly pharmaceuticals. However, it’s important to keep in mind that those experiencing illness or pain may not put sustainability at the top of their list of concerns.
