Original article: Chacay: La especie invasora que se transformó en abono y solución ambiental para Chile In an interdisciplinary conversation blending applied science, entrepreneurship, and public debate, the Universidad Católica de Temuco hosted a seminar that scrutinized one of the most problematic species in southern Chile: Chacay (Ulex europaeus). For decades regarded as an invasive weed, it is now emerging as a viable alternative within the circular economy. The event, organized by the Faculty of Natural Resources in collaboration with Rume Chacay and supported by Corfo, brought together academics, researchers, and entrepreneurs to explore productive and sustainable uses of this species.
The program featured presentations covering topics from its biological properties to its potential as an agricultural bio-input. Notably, Rodrigo Navarro, the founder of Rume Chacay, shared insights from over a decade of research on this plant and its transformation into tangible products. “What started as a basic idea has made significant advances in how to repurpose Chacay for agriculture and other uses,” Navarro explained.
Among its developments are mulching-type substrates (used to enhance soil quality) and sanitary sawdust for pets, both biodegradable and plant-based. From the academic perspective, researcher Ricardo Tighe, a key supporter of the event, highlighted the day’s focus on bridging knowledge and application. “It facilitated connections between business and science to generate results that can be beneficial in the field and have commercial potential,” emphasizing Chacay’s potential as a raw material for family agricultural practices.
Finally, the seminar included a discussion panel addressing the challenges and future directions for valorizing invasive species, calling for a reevaluation of their role in an environmental crisis context. Thus, in a landscape where innovation is at the intersection of science, territory, and market, Chacay is beginning to transform from a problem into a concrete and sustainable solution.
