Composting (aerobic treatment of organic wastes) and digestion (anaerobic treatment of organic wastes combined with biogas production) are important waste management strategies with increasing significance in the European Union and Switzerland. Most of the ...
Aerobic granular sludge technology offer a possibility to design compact wastewater treatment plant based on simultaneous COD, nitrogen and phosphate removal in a sequencing batch reactor.Simultaneous nutriment removal was possible, because of heterotrophi ...
• Goal The goal of the project was to produce biomolecular fingerprints in order to describe the structure of microbial community which develops during aerobic sludge granulation, initiated in sequencing batch wastewater treatment processes. Four SBR were ...
A microchip reactor has been developed on the basis of a layer-by-layer approach for fast and sensitive digestion of proteins. The resulting peptide analysis has been carried out by matrix-assisted laser desorption ionization timeof- flight mass spectromet ...
Material flow management has become an increasingly important paradigm in waste management. An essential goal of this paradigm is prioritizing waste reduction over reuse and recycling, and the latter waste management processes over secure disposal of waste ...
Converting wood to grid quality methane allows to distribute a CO2 free, renewable enery resource in a conventional energy distribution system and use it in transportation applications. Using a previously developed thermo–economic process model for thermoc ...
In this paper we propose a methodology to determine the structure of the pseudo-stoichiometric coefficient matrix K in a mass balance based model, i.e. the maximal number of biomasses that must be taken into account to reproduce an available data set. It c ...
In Europe, 9.3 x 10(6) t(dry weight ( dw)) of compost and digestate are produced per year. Most of this is applied to agricultural land, which can lead to considerable inputs of organic pollutants, such as polychlorinated biphenyls ( PCB) and polycyclic ar ...
Methanogenesis from main methane precursors H2/CO2 and acetate was investigated in a temperature range of 2–70 °C using sediments from Lake Baldegg, Switzerland. Psychrophilic, psychrotrophic, mesophilic, and thermophilic methanogenic microbial communities ...
Among renewable energy sources biomass plays a major role. Several paths for improving the conversion of biomass with minimum burden on the environment are being pursued worldwide. This paper reviews some of the most recent results from research at the Swi ...
