Heineken brewery: recycling ammonia effluents and organic waste to reduce the impact on the environment
In 2008, Heineken, one of the largest breweries in the world, regularly exceeded the authorised effluent discharge standards in one of its UK plants, particularly with regard to ammonia. Backed by its duel expertise in water cycle management and organic waste treatment, SUEZ set up an effluent reduction solution coupled with organic waste recycling. In this way, Heineken preserved the age-old quality of its beer and optimised its economic and environmental competitiveness.
Help Heineken to reduce its environmental footprint
In 2008, world no.3 brewer Heineken acquired John Smith's, one of the largest breweries in the UK. Located in Tadcaster, Yorkshire, the hundred-year old plant frequently exceeded the ammonia discharge levels permitted by the UK Environment Agency.
In order to satisfy environmental requirements, Heineken had to take up a major environmental challenge while sustaining its competitiveness. Objectives: lower the ammonia content in discharged water to reduce the brewery's environmental impact.
Optimise performance and reduce the environmental footprint
Identify and optimise the operating processes
- A solution to reduce nitrogen particles responsible for producing ammonia, at the inlet to the plant.
- Installation of an anaerobic digestion tank to lower the ammonia content.
Reduce energy consumption and enhance competitiveness
SUEZ also proposed that Heineken deploy energy production technologies:
- Introduction of an organic waste treatment channel with biogas recovery through methanisation.
- Production of steam and electricity using this biogas to cover the needs of the production process.
