Ecological aspects of cleaning and disinfection Part 3: Chain lubricants and amine acetates as well as proprietary cleaning agents and disinfectants

An evaluation of ecological impact of cleaning agents and disinfectants has to include chain lubricants and their individual components. Some of these agents have good microbicidal action so as to ensure hygiene on conveyer belts. The extent to which they - and a number of other cleaning agents and disinfectants - have an influence on degradability in waste water and whether they themselves are biodegradable has been investigated at the State Institute for Research and Testing of Brewing Technology in Weihenstephan.

Test methods used have been described in "Ecological aspects of cleaning and disinfection, Part 1: Monobromoacetic acid" (see "Brauwelt International" no. VI, 1999, p. 508). They were displaced by amine-based agents.

Microbiological aspects of drinking water and industrial water treatment

The present article deals with implementation of the HACCP concept. Use of chlorine dioxide makes disinfection operations more transparent and reduces running costs.

In recent decades, complicated technologies, in particular aimed at improving quality, have been introduced in various areas of the beverage and food industries. Even prior to efforts at harmonisation under EC Directives, one was certainly aware of health as well as economic implications of microbial product contamination. As a result, hygiene specifications were drawn up for all production steps.

Chlorine dioxide is a disinfectant which can be produced cheaply as needed from commercial chemicals on site.g. disinfection in the cold water zone of a bottle washer.

Ecological aspects of cleaning and disinfection Part 2: EDTA and NTA organic complexing agents

In this second part, the presence of organic complexing agents in brewery effluent, their degradability as well as possible inhibiting effects are investigated.

EDTA and NTA organic complexing agents are used for cleaning purposes in breweries to prevent precipitation of calcium and magnesium hardness in an alkaline environment. They have a chelating effect on calcium and magnesium ions which are thus withdrawn from the system and cannot react with the precipitating counterions. Typical points of use are specially formulated cleaning agents, additives for lye cleaning and conveyor lubricants.

It is said to attack concrete, can lead to a species shift in water bodies, remobilises heavy metals and contributes to eutrophication of water bodies. 508).

Efficient tank cleaning - untapped potential

The brewing and beverage industries are having to fulfil increasingly stringent requirements in terms of product safety, and also improve quality, efficiency and profitability. Production has to be flexible and efficient and be in a position to empty and refill tanks quickly and unproblematically with minimal effort. This gives a pivotal role to automatic cleaning of tanks and equipment.

Cleaning procedures in the brewing and beverage industries are usually automated to the greatest possible extent. Nevertheless, a large number of tanks and vessels are still cleaned with less efficient methods. The current most wide-spread method of vessel cleaning is with static spray balls. Increasingly, rotating spray heads are being installed.

Cyber marketing

Hugo Powell, the veteran marketer behind Labatt’s Ice Beer and recently elected President and Chief Executive of Interbrew SA, believes that the explosive growth of the Internet - it already has a 39 per cent penetration in U.S. homes and is expected to rise to 61 per cent in five years - will further the market fragmentation that has become the marketer’s nightmare. What makes matters worse is that the Internet users are disproportionately the younger, well-educated and wealthy groups that advertisers are trying to reach via mature media such as television. "Television for these people is Internet", Mr Powell declared.
