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 …

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 …

Waste disposal management and the energy crisis are important challenges facing most countries. The fruit-processing industry generates daily several tons of wastes, of which the major share comes from banana farms. Anaerobic digestion (AD) technology has been applied to the treatment of wastewater, …

In deze praktijkgerichte studie wordt door middel van literatuur en interviews duidelijk gemaakt hoe hbo-theologen hun beroepsidentiteit ervaren in de Gereformeerde Bond binnen de PKN. In deze context is er ten aanzien van de veranderende cultuur spanning waarneembaar tussen de ambtsopvatting in de …

Onderzoek naar geschikte vormen van nieuwe media voor een doelgroep van Stichting Sprank: mensen met een verstandelijke beperking in combinatie met een Autisme Spectrum Stoornis.

In dit boekwerk ‘Ciudad del Flamenco, de choreografie van het proces’, wordt het ruimtelijk ontwerp gepresenteerd, en het proces wat daar toe heeft geleidt, als antwoord op de schaduwprijsvraag ‘Ciudad del Flamenco’, destijds uitgeschreven door de gemeente van Jerez de la Frontera.
