From the start of the energy transition is has been believed that the development of wind power as a renewable source of electricity was vital for reaching the climate goals related to the decarbonization of the energy sector. The LCOE variable is globally applied when comparing the cost for the use …

Large wind turbines have recently had the energy sector’s attention given their reliability, cost-effectiveness, competitive power, and the maturity of their technology. Unfortunately, large wind turbines usually face obstacles regarding their social acceptance near rural or residential areas. On the …

High-pressure anaerobic digestion is an appealing concept since it can upgrade biogas directly within the reactor. However, the decline of pH caused by the dissolution of CO2 is the main barrier that prevents a good operating high-pressure anaerobic digestion process. Therefore, in this study, a high-pressure …

A bioaugmentation approach was used to enhance the performance of anaerobic digestion (AD) using cow manure (CM) as the substrate in a continuous system. To obtain the desirable microbial culture for bioaugmentation, a biochemical methane potential test (BMP) was used to evaluate three commonly used …

Many articles have been published on scale-down concepts as well as additive manufacturing techniques. However, information is scarce when miniaturization and 3D printing are applied in the fabrication of bioreactor systems. Therefore, garnering information for the interfaces between miniaturization …

De Haagse Morgensterkerk (GKv) verandert ongepland van een blanke kerk in een gemêleerde, interculturele gemeenschap. De voorganger, ds Gerrit den Broeder, vertelt het verhaal van deze omwenteling en de vreugde én de uitdagingen die dat met zich meebrengt. Aansluitend reageren Nadine van Hierden en Sake …

OBJECTIVES: To evaluate the clinical performance of partial glass-ceramic (IPS e.max Press) posterior restorations. MATERIALS AND METHODS: A total of 765 restorations in 158 patients were placed between 2008 and 2018 and evaluated in a prospective study during regular dental care visits between 2015 …

This study evaluated the performance of anaerobic co-digestion of cow manure (CM) and sheep manure (SM) in both batch and continuous digesters at 37 °C. Synergistic effects of co-digesting CM and SM at varying volatile solids (VS) ratios (1:0, 0:1, 3:1, 1:1, 1:3) were observed in the batch experiment, …

Polyhydroxyalkanoates (PHAs) form a highly promising class of bioplastics for the transition from fossil fuel-based plastics to bio-renewable and biodegradable plastics. Mixed microbial consortia (MMC) are known to be able to produce PHAs from organic waste streams. Knowledge of key-microbes and their …

Due to the exhaustion and increased pressure regarding the environmental and political aspects of fossil fuels, the industrial focus has switched towards renewable energy resources. Lignocellulosic biowaste can come from several sources, such as industrial waste, agricultural waste, forestry waste, and …
