High-quality manure and lower traffic

In the Veluwe region a project was started in 2005 for the annual removal of approximately 45,000 cubic metres (1.6 million cubic feet) of slurry produced in the region’s veal fattening farms via a pressure discharge pipeline. This required the construction of 23 kilometres (14 miles) of pressure discharge pipelines, with approximately 30 connections for the veal fattening farms. This reduces the number of tank trucks on public roads by about 1,500.

The system pumps the slurry directly from the farms to a collection depot near the village of Stroe. This brings about a noticeable reduction in noxious smells and ammonia emissions. Furthermore, in the event of an outbreak of diseases such as foot-and-mouth disease or bird flu, manure transportation via the pressure discharge pipeline can continue as usual.

Central management thanks to C.A.R.S

The central server indicates when an underground slurry reservoir is almost full. The operator sends a message to the farmer to request permission to empty the reservoir. At the push of a button the reservoir is then emptied by a pump installed at that farm. C.A.R.S records the slurry volume, determines its density, and takes samples. Next comes the processing of the slurry: the solid components are separated from the liquid. The liquid is discharged via the sewage system to a water treatment plant. The solid components are turned into fertilizer that is suitable for agricultural use and for sale in garden centres.
A nice project that contributes to traffic safety, ammonia emissions reduction, and to a good end product as a bonus.
