Agriculture and food science literature on waste-to-value applications that allow upcycling of byproduct ingredients is increasing. However, this stream of research rarely takes an international
trade and sustainability systems perspective. This focused review defines the term of waste-tovalue and the sustainable development goals connected to it, and points to the tensions and
questions arising when international trade is involved. Further, it exemplifies the challenges and
opportunities of waste-to-value in tropical fruit trade through five cases of tropical fruit from
South America: Green coconut, ac¸aı, maracuja, cambuci, and jabuticaba. We present a model of
the international supply chain that indicates where the opportunities of waste-to-value applications in international tropical fruit trade are situated, and discuss which future research questions
need to be addressed to tackle the challenges of waste-to-value in global tropical fruit chains.
Establishing the waste-to-value approach in the export of yet-underused tropical fruits can
amongst others improve local employment, preserve natural resources, allow favorable use of
side-streams in local energy production, environmentally friendly packaging material for transport,
and add health functionalities to the end-consumer products, but challenges have to be solved in
order to ensure these environmental and social benefits materialize.
