Industrial, agricultural, and domestic sectors have an impact on the pollution of surface waters. More specifically, discharges of wastewater treatment plants also have a major impact on the quality of surface waters. According to PBL Netherlands Environmental Assessment Agency, Dutch surface waters …

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 …

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 …

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 …

Using either freshly pulped or preserved seaweed biomass for the extraction of protein can have a great effect on the amount of protein that can be extracted. In this study, the effect of four preservation techniques (frozen, freeze-dried, and air-dried at 40 and 70 °C) on the protein extractability, …

Renewing agricultural grasslands for improved yields and forage quality generally involves eliminating standing vegetation with herbicides, ploughing and reseeding. However, grassland renewal may negatively affect soil quality and related ecosystem services. On clay soil in the north of the Netherlands, …

In 1990, livestock grazing was introduced in Meijendel, a 1800 ha lime-rich coastal dune area, at a density of 0.06–0.07 LLU.ha-1.year−1 (1:12–18 ha) to counteract encroachment of tall grasses and shrubland on dune grassland and increase the bare sand area. Monitoring was based on four digital orthophotos …

Decomposition is an ecosystem process, mainly important in the carbon and nitrogen cycles. When looking at what drives decomposition, there are three major drivers. These are plant litter quality, microbes and soil animals (detritivores). A large problem in understanding the decomposition process is …

Microalgae can produce a wide range of valuable metabolites such as proteins, lipids and pigments, so they can be used in many ways. For aquaculture industry, microalgae are usually used as live feed because of their high nutritional level. Fry Marine(Vlissingen, NL) is a hatchery for marine feed and …

In the search for low greenhouse gas propulsion, the dual fuel engine provides a solution to use low carbon fuel at diesel-like high efficiency. Also a lower emission of NOx and particles can be achieved by replacing a substantial part of the diesel fuel by for example natural gas. Limitations can be …
