Believe it or not, cashew shells are an important part of our business. The circular journey of the cashew shells starts at our factory. To power the steaming and drying process of our cashews, we use an innovative gasifier furnace that runs on leftover cashew shells. We then use the resulting biochar as a super carbon-rich fertilizer for our cashew trees and rosella plantations.
Our excess cashew shells we pass on to other small businesses, such as commercial laundries, which use the shells to heat their boilers. While the shells may seem like a simple byproduct with little value compared to the cashews themselves, they’re actually integral to our operations and need to be managed with care.
In 2016, we started to take the “use the whole cashew” idea to the next level. We have ambitious plans to replant Bali’s – and eventually Indonesia’s – cashew trees within the next decade. Part of this plan involves buying old cashew trees from farmers to make space for the new seedlings. We are using the wood chips from these trees to fire our furnaces as well, leaving no part of the cashew – or its tree – unused.
