In Europe, disinfectants (biocides) used in the food industry are controlled by a range of legislation, but two are key in determining the level of disinfectant that can be taken up by foodstuffs after the disinfectant’s legitimate use.

Water reuse and recycling in the food industry

Issue 6 2012  •  11 January 2013  •  Anke Fendler, Environmental & Innovative Technologies Specialist, Campden BRI

Water is an essential resource for food and drink production. With water scarcity worldwide a serious concern, there is a need for industry to address the impact of its water consumption and consider ways in which it can optimise water use in the future whilst ensuring the safety and wholesomeness of its products. This article discusses legal, quality and safety issues for reuse and recycling of water in the food industry and gives an overview of possible treatment technologies.

Water is scarce worldwide. Some recent examples include the severe drought of summer 2012 affecting 80 per cent of the United States as well as parts of Mexico and Central and Eastern Canada1, and the risk of a serious drought in the South East of England after an exceptionally dry winter, only averted by persistent heavy rainfall in recent months2. Water use has been growing at more than twice the rate of popula tion increase in the last century, and around 1.2 billion people, or almost one fifth of the world’s population, now live in areas of physical water scarcity3.

Water scarcity directly impacts on all areas of food production. Water is used throughout the food production process as an ingredient and in unit operations such as food cleaning, sanitising, peeling, cooking or cooling. Water is also used as a conveyor to transport food materials through the process. Finally, water is used to clean production equipment between operations.
