Our responsible supply chain in Peru with Deshidratados Tropicales Avocado, maracuja and maca are part of the composition of many Expanscience products and active ingredients. These raw materials come from sustainable, fair-trade crops, most notably in Peru. Sourcing and the transformation of these raw materials are ensured by Deshidratados Tropicales, our local implantation. In this way, we control the entire supply chain and reduce our environmental and social impact. #SustainableCrop Protection of local biodiversity Combat deforestation #Employment: 350 avocado producers supported by our activity in Peru #EconomicDevelopment Sustainable crops thanks to a long-term commitment Fair prices for producers To learn more about other actions, go to the “Our Purpose” page !
