Hazelnut shells could fuel the future with renewable xylose and furfural.
The researchers studied how heating hazelnut shells with acid can make sugar and furfural. They found that heating at 120°C for 10 minutes gave the most sugar (xylose), while heating at 160°C for 30 minutes gave the most furfural. Heating at higher temperatures decreased sugar production but increased furfural. This method could be useful for making these chemicals from agricultural waste.
