The Zürich-based Pakka Fundation is involved in fourteen nut production units worldwide. As part of the project Pyro-Power Colombia, it collaborates closely with Generation Carbon to develop pyrolysis systems to improve organic waste management in cashew nuts plantations. The two organisations guarantee that the higher standards in term of sustainability are met.
Pyrolysis systems allow to recycle specific type of waste such as cashew nut shells. This technique consists in heating the organic waste at a high temperature to transform it into a new material called biochar. Biochar can then be used for various ends, such as soil fertilisation. The heat produced during the pyrolysis process is reused to dry the cashew. Eventually, the process could be adapted to other waste products.
