Biogas production involves the complex process of anaerobic digestion in bioreactors. This paper presents numerical modeling results and analysis of bioreactors. We discuss research methodology, model geometry, internal bioreactor processes, and possible modifications. Two mathematical models and their …

Climate change calls for an energy transition utilizing all available renewable energy resources, such as bioenergy from biomass. However, the use of biomass is debated in society, and public acceptance is low or lacking. This survey-based research demonstrates for the first time that public acceptance …

The topic of this bachelor's thesis is an investigation of the manure solids produced during the separation of cow manure for suitability as bedding in horse stalls. The aim is to show the aspects of this material that influence the health of horses, but also with regard to the sustainability aspect …

Problems of energy security, diversification of energy sources, and improvement of technologies (including alternatives) for obtaining motor fuels have become a priority of science and practice today. Many scientists devote their scientific research to the problems of obtaining effective brands of alternative …

The biodiversity in the Netherlands is at an all-time low, in 2020 this was at a level of 15% especially while compared to Europe’s average of 40%. The biggest cause for this is intensive agriculture and lack of livable space for a wide variety of plants and animals. In the agricultural sector this is …

The following research justification report shows to which extent adding HemCell prebiotics to the current product line is financially feasible. Before coming up with a calculation model, some more background research needed to be done. Four information gaps were identified on which this research is …

The aim of this research was to find out in how far the Netherlands could learn from Sweden regarding the use of manure, in order to create awareness within the equine sector on sustainable solutions. The number of horses in Europe exceeds 5 million and keeps increasing, therefore contributes to greenhouse …

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 …

The 'AgroCycle' project investigates whether a cooperation of farms can become self-sufficient in energy and fertilization by using manure and organic waste streams for the production of energy, green fuel and green fertilizers by means of anaerobic digestion (AD). In the project, the project partners …

This study was conducted to investigate dairy farming practices and gross margin at smallholder dairy farmer level to design a business model for scaling up climate-smart dairy in Ziway-Hawassa milk shed. 80 sample dairy farmers from five districts (which then categorised as urban and peri-urban dairy …
