To this end, we have an anaerobic pilot plant station and another testing plant in accordance with DIN 38414-S8 at our disposal for investigations to analyse the potential, quality, composition and reaction kinetics of biogas from all residues. In a research project funded by the Federal Office for Agriculture and Food, these testing facilities have already been used to develop a process to purify and reuse waste water and production residues from wine-making on individual vineyards. The thermal use of solid residues was investigated on the basis of a patented invention. Here, a method was developed that enables fuel pellets to be produced from pressing residues from wine-making, also called pomace. In Germany alone, approximately 330,000 t/a of grape pomace are potentially available, constituting an interesting and, above all, previously unused source for the supply of energy. Due to the grape seed oil released during processing, which acts as a binding agent, the pressed pellets are highly solid, fulfilling all of the relevant quality demands. Thanks to the energy-rich grape seed oils, the determination of calorific values revealed higher energy contents than wood pellets.
