Smart, safe and circular (SMASC)

Purpose and goal

In close contact with industrial partners we have performed risk analyses when introducing circular systems related to food industry. Our recommendations are to always perform microbial risk assessments as circular systems might have inherent differences compared to linear systems, for example problems due to accumulation of microorganisms. We also recommend performing Life Cycle Analyses to make sure there is an environmental benefit. We can also conclude that the current legislation could be a barrier preventing circular initiatives and solution.

Expected results and effects

Our overall assessment is that, when introducing a circular solution, one should look at microbiological risks. The re-circulation process itself has a major impact on whether, for example, microorganisms can survive and accumulate. When introducing a new circular solution, a life cycle analysis should be undertaken to quantify the environmental benefit, since it is not definite that re-circulation is beneficial from an environmental viewpoint. A reasonable attitude is that you should always have re-circulation in mind before planning a new product or process.

Planned approach and implementation

The project was divided into part for the project group based on previous experience and expert competence. A lot of reading and consultation was required with external experts and government representatives to get familiar with current legislation and understand its practical significance. Our business partners had initial responsibility for their respective cases, and according to the plan, researchers from RISE were involved contributing with advice and critical review. A significant part of the project comprised in putting together and reviewing the final project report.
