A team of researchers at the University of "Bath" in Britain has succeeded in devising a new method for making two of the most common pain relievers, "ibuprofen" and "acetaminophen", known as "paracetamol", based on a chemical compound found in pine trees, and it can be obtained from waste in the paper industry, according to a report by ScienceAlert.
British chemist Josh Tibbets, who is leading the research, explained that the compound extracted from waste paper is called beta-pinene, and it comes from turpentine.
He also noted that researchers have been able to make many other beneficial chemicals from turpentine, including those that can be developed into cleaning products, asthma medications, and beta-blockers used to treat certain conditions of high blood pressure.
The method used by Tibbets' team is based on what are known as "continuous flow reactions", because chemical reactions occur continuously rather than in batches, acting like a conveyor belt for chemicals.
This method may be more expensive
"A carefully calibrated series of reactions is needed to move from beta-pinene to intermediates for acetaminophen and ibuprofen," the British researcher explained.
He pointed out that research still needs further development before it can be used commercially, stressing that it may be more expensive than industry methods that depend on crude oil.
It is noteworthy that many common medicines are chemicals that come from crude oil, a condition that must be changed in order to reduce dependence on fossil fuels, which contribute to raising levels of environmental pollution and increasing the risks of global warming and climate change.
