This report contains the results of the graduation research of Jurre Kuijper and Martin Volgers. The research goal is to find an appropriate model to calculate the heat transfer under different sets of system conditions. The system in this case is a sewer heat system, which consists of a sewage pipe …

As a means to decrease the amount of waste tires and to re-use tire rubber for new tires, devulcanization of ground passenger car tires is a promising process. Being an established process for NR and EPDM, earlier work has shown that for ground passenger car tire rubber with a relatively high amount …

Anaerobic digestion (AD) can play an important role in achieving the renewable energy goals set within the European Union. Within this article the focus is placed on reaching the Dutch local renewable production goal set for the year 2020 with locally available biomass waste flows, avoiding intensive …

Improving the sustainability of the Anaerobic Digestion (AD) process through modeling.Presentation given at the European Biomass Conference & Exhibition 2016 in Amsterdam regarding the local waste biomass availability for Anaerobic Digestion, the local biogas yield, and the optimization of farm based …

Plasma gasification has been studied as a new technology which may combine bio-waste treatment and energy generation. Currently, a setup for carrying out gasification experiments has been built up in order to obtain more experimental data for further research. According to previous experimental results, …

Biogas produced through Anaerobic Digestion can be seen as a flexible and storable energy carrier. However, the environmental sustainability and efficiency of biogas production is not fully understood. Within this article the use, operation, structure, validation, and results of a model for the environmental …

Anaerobic digestion (AD) can play an important role in achieving renewable goals set within the Netherlands which strives for 40 PJ bio-energy in the year 2020. This research focusses on reaching this goal with locally available biomass waste flows (e.g. manures, grasses, harvest remains, municipal organic …

BACKGROUND: Hemodialysis patients experience an elevated risk of malnutrition associated with increased morbidity and mortality. Nocturnal hemodialysis (NHD) results in more effective removal of waste products and fluids. Therefore, diet and fluid restrictions are less restricted in NHD patients. However, …

In many cities, pilot projects are set up to test or develop new technologies that improve sustainability, urban quality of life or urban services (often labelled as “smart city” projects). Typically, these projects are supported by the municipality, funded by subsidies, and run in partnerships. Many …

The energy efficiency and sustainability of an anaerobic green gas production pathway was evaluated, taking into account five biomass feedstocks, optimization of the green gas production pathway, replacement of current waste management pathways by mitigation, and transport of the feedstocks. Sustainability …
