At the end of 2012 and early 2013 there has been a study at SIC Sterksel to frequent indulgences of manure out of manure trays by under pressure. After a few modifications there is now a system available to apply in practice.
The goal of this study was to develop a new sort of system for finishing pigs with daily indulgences of manure out of manure trays by under pressure. With this system the climate becomes more fresh and ammonia and odour emissions get reduced.
With the system also fresh manure becomes available, which gives a high biogas yield.
