On 19th July 2018, the Province of Overijssel made a provinciaal inpassingsplan/provincial integration plan (pip) available for inspection, outlining plans for the construction of a manure processing plant at the Elhorst-Vloedbelt landfill site in Zenderen. The pip and the environmental permit application will be available for viewing until 19th September. In mid-December, the province will make a decision as to whether the zoning plan and permit will become final. After this, the selected contractor, Twence, can start building the facility.
The new manure processing facility will have capacity to process 250,000 tonnes of manure each year, representing around a quarter of Ost-Nederland's current annual manure surplus. The facility will convert the manure into phosphate and potassium fertilisers, ammonia water, clean water and biogas. The manure processing plant will be located in closed halls under the landfill site's existing transfer hall.
The site will continue to serve as a landfill, with an unchanged total capacity of 4.8 million cubic metres. However, when the manure processing installation is completed, the annual amount of waste received by the landfill will be reduced from 190,000 tonnes per annum (tpa) to 95,000 tpa. The supply of waste will be reduced from 19,000 deliveries per year to 7,000.
In April 2016, the Provincial Executive of Overijssel granted an environmental permit for the facility, but this licence was annulled by the Administrative Jurisdiction Division of the Council of State in October 2017. As the Province of Overijssel is of the opinion that the construction of a manure treatment plant at the Elhorst-Vloedbelt location is of provincial importance, it has decided to establish the pip, in the belief that the manure processing plant's social purpose transcends local interests.
