In store pre-treatment
The novelty we propose aims to implement a pre-treatment process, in-store, of the retail food waste in order to transform it into a dehydrated “powder” that can be used for microalgae feed.
Simply put, all that is needed is a dryer machine that, thanks to automatic temperature and humidity control, dries and crushes the waste until just a powder, with less than 80% of the initial volume, is left.
Then, this “powder” needs to be valorised. To use these types of food waste into a circular economy approach its preferable to link the solutions with high value added applications that can cover the corresponding costs and ensure the economic feasibility of the valorisation process.
