About Westfort

Westfort is a specialised pork company that controls the entire processing chain: from purchasing, meat processing and meat products to the worldwide delivery of quality meat to various customers. Created after a merger of Lunenburg Vlees uit Oudewater and Egbert Kruiswijk Vleesproducten from IJsselstein, Westfort concentrates slaughtering, processing and freezing capacity at one location in IJsselstein within the foreseeable future.

At the end of 2015, the completely new slaughterhouse in IJsselstein was put into operation. A unique slaughterhouse with innovations in the field of animal welfare, automation and the environment.

Our project

The new factory was designed with a great deal of attention towards sustainability. An important aspect of this, is the self-sufficiency of energy and the efficient way of waste water treatment.

The production of meat generates a lot of waste water. More than 1400 m3 of waste water must be treated to meet the requirements of the permit daily.

Other requirements that applied were: limited footprint (limited space), sustainability (low energy consumption) and robustness (continuity of the business process).

Raw material efficiency

Robust, reliable and proven technique to generate bio-energy, fertilizers and water.

The modern slaughterhouse of Westfort Vleesproducten has access to sludge treatment and a fully-fledged wastewater treatment plant (90m3/hour). In addition to flotation and partial flow membrane filtration, the waste water treatment plant consists of two Nereda® reactors. The Nereda process is characterized by a very compact design, very low energy consumption and its robustness.

Westfort produces 20% of its own electrical capacity and 80% of its own thermal capacity with an innovative fermentation unit. The methane gas produced by the fermentation process is burned in the combined heat and power plant, resulting in green energy of 500 kWh. In addition, the fermentation plant processes the residual flows into natural fertilizers.

The mechanical and electrical installation of this water treatment plant with fermentation unit is carried out by RWB as part of a construction team (design & construction). RWB also designed and installed a source water treatment system.

Our customer speaks

“Last year, one of the most progressive – if not the most progressive – slaughterhouses in the world for Westfort meat products was realized in IJsselstein. An important part of the overall process is the water purification and fermentation carried out by RWB, in which the innovative Nereda® technology patented by Royal Haskoning DHV is applied.”

“Self-sustainable entrepreneurship with attention for the environment and sustainability”

In IJsselstein, one of the most progressive slaughterhouses in the world has been realized.

A sustainable slaughterhouse where more than 500 kWh of own energy is generated from the slaughterhouse waste. That is equivalent to the electricity of 1.750 large families. The residual product from the digester is processed into organic fertilizer and water that can be discharged. This will result in an 80% reduction in the transport of residual flows.
