A lot still needs to be done with regard to biowaste. While 1.3 million tonnes of biowaste are turned into recycled fertilisers, 4.2 million tonnes are incinerated each year. In addition, a substantial share of food that’s thrown away, more than 50%, is still edible.51 Food consumption in Switzerland generates 2.8 million tonnes of avoidable food waste per year at all stages of the food chain, both in Switzerland and abroad. Per person and per year, CHF 600 go to waste. The environmental impact of food waste occurs: 38% in households, 14% in gastronomy, 8% in wholesale and retail, 27% in processing and 13% in agricultural production.

Product and process design needs to take food waste into account and design-out food waste.
