University of Queensland identifies invasive weeds as lignin‑rich feedstock

In Australia (Queensland), University of Queensland researchers have reported that 15 invasive weed species around Ipswich—including Brazilian Nightshade and Climbing Asparagus—contain high lignin contents (~25 %), making them promising feedstock for compacted biomass pellets. The initiative aims to convert environmental nuisance species into sustainable feedstock for biodiesel and renewable diesel, promoting circular economy innovation. While early in development, the study supports scalable and low‑cost biomass sourcing routes beyond traditional crops. — Source: UQ news and QAAFI reports (enerkem.com) enerkem.com
