At an aquaponics farm in Luxembourg called “Fësch Haff” the effect of the water quality on the growth rate and behaviour of the rainbow trout has been analysed. Three times a week the water quality in the fish tank expressed by temperature, KH (carbonate hardness), pH, ammonium/ammonia, nitrite, nitrate …

The emission of greenhouse gasses is a trending subject worldwide. Also the maritime industry is looking for alternative options for zero-emission transport. Nedstack provides fuel cells as a solution for this challenge. This research is a first glance at the possibilities to create a feasible retrofit …

Ammonia is heavily used in agriculture as a fertilizer and in industry as a raw material for the production of various organic nitrogen compounds. Its high hydrogen content and its established infrastructure for both storage and distribution makes ammonia a prominent candidate for storing fluctuating …

This study originates from an increasing demand for seaweed cultivation. HZ University of Applied Sciences, together with farmers, under the umbrella “Living Lab Schouwen Duiveland” will conduct a field study to assess the possibilities for introducing brown seaweed cultivation at or near existing mussel …

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 …

Materials with semiconducting properties are present in every microelectronic device and form the backbone of our information society. Commonly used inorganic semiconductors are poorly modular and their production is expensive and energetically demanding. Moreover, the use of metals and critical raw …

Kunstmest voor de velden en brandstof voor landbouwvoertuigen zijn belangrijke kostenposten voor de landbouw. Kunstmest en dieselbrandstof zijn energie-intensieve producten en daarmee ook een belangrijke bron van CO2 emissies vanuit de landbouw. Technologie voor hernieuwbare energie zoals zonne- en wind …

This report focuses on the feasibility of the power-to-ammonia concept. Power-to-ammonia uses produced excess renewable electricity to electrolyze water, and then to react the obtained hydrogen with nitrogen, which is obtained through air separation, to produce ammonia. This process may be used as a …

For the recycling of carpet and artificial turf the latex backing is often a real stumble block. Many strategies have been developed like freezing the carpet, followed by grinding and subsequent separation of the milled particles. Once it has been separated from its backing materials, PA 6 is relatively …
