Abstract
In this manuscript, we analyze hydrothermal processes applied to four very different side stream biomasses (chestnut foliage, sugar beet pressing chips, pine bark and branches from park cleaning, bamboo cuts) and identify diverse soluble products in dependence of the starting pH of the reaction covering mild to strong basic conditions. Despite biological diversity of starting products, hydrothermal disintegration of biomass results in a remarkable reduction of chemical diversity towards a controllable number of molecular products, and the well resolved and rather simple NMR-spectra allow assignment of the products to only a few families of compounds. We discuss diverse valorization schemes depending on the biomass and conditions applied
