Location: Sassenheim, NL

Company: AkzoNobel

We’ve been pioneering a world of possibilities to bring surfaces to life for well over 200 years. As experts in making coatings, there’s a good chance you’re only ever a few meters away from one of our products. Our world class portfolio of brands – including Dulux, International, Sikkens and Interpon – is trusted by customers around the globe. We’re active in more than 150 countries and have set our sights on becoming the global industry leader. It’s what you’d expect from the most sustainable paints company, which has been inventing the future for more than two centuries.

Job Purpose

Nowadays, more environmentally friendly water borne paints are produced instead of solvent borne paints by AkzoNobel. Increase in the water percentage in paint production increases the risk of microbial contamination. There are two ways to avoid contamination issues

a)    preservation of water based products
b)    ensuring good plant hygiene to allow continuous manufacturing activities and reduction of the contamination of products.
In Microbiology Expertise Group (MBEG) we perform microbiological tests with our Deco paints in a laboratory or field/production environment, taking into account necessary technical, legal, HSE and Product Stewardship principles. MBEG performs tests to optimize biocide packages (preservation) for different product categories. Accordingly, different biocides are tested with an in-can challenge test.  Furthermore, tests are done to evaluate the performance of different sanitizers against planktonic microorganisms as well as biofilm to be used in production. Until now, we have tested performance of sanitizer against biofilm in water. The plan is to test the sanitizers in paint (white wash water) environment. 

The plan is to create old biofilm of fungi and bacteria in water and white water environment and check the performance of the sanitizers. Since the incubation time is long, it is expected to participate other running projects.
