This literature review identified and categorised circular economy (CE) practices within all stages of the food and feed production chain in Europe to provide an overview of current and envisaged practices. There are four macro areas:

1. primary production of food and feed
2. reducing industrial/manufacturing/processing waste
3. reducing food and feed waste in wholesale, food retail, catering and households and
4. reducing food and feed packaging waste.

It is recommended that future primary research in novel food and feed in the CE focuses on areas other than insect farming, and that there are further investigations into the potential risks associated with importation into the EU of livestock/goods that may have been subject to different restrictions/legislation.
