The overriding purpose of the thesis research is to develop new design concepts for improved and sustainable asphalt mixes. To accomplish this goal, it became necessary to reach some prerequisite goals. Determining what a sustainable asphalt means, and how that ideal is connected with the field of asphalt …

Dekker wil weten of de huidige stand van zaken met betrekking tot puin- en houtverwerking wel de meest duurzame oplossing van deze afvalstromen is. Als alternatief heeft Dekker drie voorstellen van alternatieve verwerking gedaan. Dit onderzoek is uitgevoerd om helderheid te verschaffen over de duurzaamheid …

In the current discourses on sustainable development, one can discern two main intellectual cultures: an analytic one focusing on measuring problems and prioritizing measures, (Life Cycle Analysis (LCA), Mass Flow Analysis (MFA), etc.) and; a policy/management one, focusing on long term change, change …

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 …

Presentation given to a delegation from the University of Oldenburg and the Research company Next Energy to explore fields of collaboration in research topics.

The environmental impact of Synthetic Natural Gas (SNG) production from wood gasification is analysed, focusing on the comparison of two continuous processes (CO2 removal and Fuel-assisted hydrogen addition) to balance the gas mix for the methanation, and their coupling to an intermittent process (Full …

Biogas plays an important role in many future renewable energy scenarios as a source of storable and easily extracted form of renewable energy. However, there remains uncertainty as to which sources of biomass can provide a net energy gain while being harvested in a sustainable, ecologically friendly …
