Methaanoxidatie bij mestopslagen: Voortgangsverslag deel 1: werking en aandachtspunten voor 3 methaanoxidatie technieken

This project has focussed on researching the possibilities of capturing methane at manure storages and subsequently convert (oxidise) it into CO2. For three types of manure storages (manure bags, manure silos and manure basins) a test was performed to capture methane with as few as possible adjustments to existing storage facilities. Subsequently, a pilot was carried out with three different methane oxidation techniques with manure bags; chemical oxidation with a torch and biologically oxidation with a biofilter and a soilfilter. The first tests show that for all three techniques it is possible to oxidize methane with an efficiency of >95%, 60-80% and 60-70% respectively. Calculations with a methane production model and a cost analysis show that cost efficiency is highest if manure is stored as quickly as possible in a manure storage coupled to a methane oxidation technique. The field filter is the cheapest solution, but the total amount of methane converted is higher with flaring and the biofilter. In addition, the parties who will be involved in, among other things, licensing and control of the techniques were interviewed. The interviews show that assurance of the continued working of the technique and enforcement will play a crucial role in the acceptance of the techniques in livestock farming.
