In a comparison between source separation and central sorting of food waste, the latter turns out to be a better choice regarding economic aspects. The main reason for this is that the capital costs related to central sorting are lower compared to the costs for a system with source separation of the food waste. Regarding the environmental aspects, the two systems are almost equal. Uncertainties within the results primarily concern the performance of a central sorting system. Even though it's not evident, the assumption made is that the sorted fractions from the central sorting facility hold an equal quality with the one from a source separation system.
