Biological degradation of oils and greases in professional kitchen ventilation

Purpose and goal

The overall target of the project was to develop a cleaning system based on biotechnogy that could break down in an efficient manner grease deposits in the ventilation systems of catering establishments. It was also a target to achieve so high an efficiency that it would be possible to apply the technology on all types of catering ventilation. The target was to develop technology that would function satisfactorily at fast-food outlets and restaurants working at high capacity. Both the biological development and the technical development exceeded all expectations.

Results and expected effects

The project has resulted in it now being possible for Bioteria to offer cleaning technology based on biotechnology that is able to minimise the accumulation of grease in catering ventilation. Our expected effects of the result are that the technology will be adopted by the market, and that it will contribute to building a sustainable society. The technology means also that our expectations that Bioteria can carry out a successful export drive have increased dramatically.

Approach and implementation

The project was divided into three subprojects and seven work packages (WP) The three subprojects were: a) to develop a biotechnological liquid product containing selected adapted bacteria that can hydrolyse grease efficiently, which would be able to minimise grease deposits in ventilation systems and heat exchangers b) to develop an application technology for optimal dosing and rinsing methods c) to develop an innovative filter housing in which the biotechnology was built-in, in order to minimise loss of pressure, fire risk and the high noise levels.
