The aim of the project Biobased Fertilisers Achterhoek (‘Kunstmestvrije Achterhoek’ in Dutch) is to make fertilisation practices more sustainable through the use of locally available nutrients from renewable sources. The project is part of the Sixth Action Programme of the Netherlands which serves the Nitrates Directive. One of the objectives was t...

In dit rapport zijn de resultaten bijeengebracht van de meetcampagne die is uitgevoerd bij drie typen mestverwerkingsinstallaties (MVI’s) voor varkensdrijfmest: omgekeerde osmose (OO), membraanbioreactor met ultrafiltratie (MBR-UF) en indampen, en bij biologische voorzuivering van kalvergier. Deze studie is uitgevoerd om beter zicht te krijgen op d...
Groot Zevert Vergisting (GZV), located in Beltrum, the Netherlands, started its biogas production in 2004. The plant has a processing capacity of 135 kilotonnes (kt) of feedstock through mesophilic digestion per year. In 2019, GZV started with the production of biobased fertilisers and purified water from digestate. The aim is to offer a sustainabl...
Dit rapport presenteert de resultaten van metingen die zijn uitgevoerd bij verschillende typen mestverwerkingsinstallaties, te weten biologische behandeling, compostering, drogen, indampen, biomembraanfiltratie, omgekeerde osmose en vergisting. Het doel was de effecten in kaart te brengen van deze manieren van mestverwerking op het voorkomen van pa...
In de producten van verschillende mestverwerkingsprocessen zijn de concentraties gemeten van een aantal pathogenen. De resultaten laten zien dat mechanische scheiding vrijwel geen effect heeft op het aantal pathogenen. Vergisting heeft weinig effect op virussen en grampositieve bacteriën, maar reduceert wel het aantal gramnegatieve bacteriën. Gramp...
Membrane filtration of ground, surface, or sea water by reverse osmosis results in permeate, which is almost free from minerals. Minerals may be added afterwards, not only to comply with (legal) standards and to enhance chemical stability, but also to improve the taste of drinking water made from permeate. Both the nature and the concentrations of ...
From 2009 to 2011 the agricultural, economic and environmental effects of the production and use of mineral concentrates, produced from animal slurry, were studied. Part of the study was the monitoring of the 8 participating full-scale (pilot) plants to assess the chemical composition of the half products and the end products of the process. In 201...
