In Spain, a study by the Universitat Rovira i Virgili (URV) has evaluated how to extract oil from coffee grounds efficiently while preserving the rest of the plant material so that it can also be utilized in other processes. The research, published in Biomass and Bioenergy, focuses on spent coffee grounds, which are a very […]
In Australia, RMIT researchers are advancing new ways to cut the carbon footprint of infrastructure by turning everyday organic waste into useful construction materials. A life-cycle analysis has shown, for the first time, that biochar made from spent coffee grounds can help produce a lower‑carbon concrete while supporting strength benefits seen in earlier lab trials.

In the UK, Aston University researchers have produced high-quality biodiesel after ‘feeding’ and growing microalgae on leftover coffee grounds. In just the UK, approximately 98 million cups of coffee are drunk each day, contributing to a massive amount of spent coffee grounds which are processed as general waste, often ending up in landfill or incineration.
