Development of a device for the production of Bokashi

A co-design experience with the producers of the Cooperative “Federación Rural para la Producción y el Arraigo” in agroecological transition

Abstract

This paper describes an agroecological Circular Economy project that promotes the cooperation of various actors with the aim of generating a bioinput using organic waste, prioritizing local markets, and contributing to sustainable and inclusive development. The project was implemented in the horticultural belt of La Plata, a sector facing challenges due to the intensive use of agrochemicals that affect the health of consumers and workers. To mitigate this problem, some producers began using bioinputs, such as Bokashi, made from crop residues and other mineral and organic components.

With funding from the Ministry of Science, Technology, and Innovation through the PAD Program, a device was co-designed to facilitate the production of Bokashi, improving its performance, work ergonomics, and compost quality. This device can be replicated by local producers using standardized elements and simple hand tools, following a self-construction tutorial. The project included visits to productive units, Bokashi production workshops, and the co-design of prototypes together with the workers. After testing and improving the devices, a self-construction workshop was held where four devices were produced, which were distributed among groups of cooperative women for their evaluation and regular use.
