Managing dairy excreta as slurry can result in significant emissions of ammonia (NH3) and greenhouse gases (GHGs) during storage and thereafter. Additionally, slurry often has an imbalanced nitrogen (N) to phosphorus (P) ratio for crop fertilization. While various treatments exist to address emissions …

De toekomst van de zeevaart ziet er volgens Martien Visser zonnig uit. “We hebben weliswaar de ambitie minder afhankelijk te worden van landen van buiten Europa, maar in de praktijk komt daar niets van terecht. We willen zelfs geen datacenters. Extra belangrijk dus te werken aan een CO2-vrije internationale …

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 …
