At a time when increasing attention is paid to sustainability in chemistry, levulinic acid (LA) is one of the most important platform chemicals for the goal of overcoming our dependence on fossil raw materials. However, a so far limiting obstacle on the way to efficient LA production from biomass is the formation of undesirable humin byproducts. In this work, a new catalytic route for the effective utilization of these humin byproducts, enabling a cyclic synthesis of LA using formic acid (FA) as organocatalyst is proposed.

The implementation of a nationwide ban on fireworks during the New Year festivities was only temporarily enforced as part of the protective measures during the Covid-19 pandemic. These two exceptional years provide an opportunity for evaluation as a model experiment to demonstrate the impact of a fireworks ban on the frequency of explosion-related hand injuries.
