Beyond-Katrili: An Innovation Rooted in Circular Economy
At the heart of Project Beyond-Katrili is the innovative integration of geothermal energy research with advanced agricultural technology to formulate a unique agricultural booster. This groundbreaking product is primarily based on geothermal silica, a byproduct traditionally requiring careful management in geothermal operations, combined with chitosan. Crucially, the chitosan component is derived from waste materials, specifically shrimp and crab shells, which are abundant byproducts of Indonesia’s vibrant fisheries industry. This dual-component formula is designed to significantly improve soil quality, enhance nutrient uptake, and stimulate robust plant growth, thereby contributing to higher crop yields and healthier produce.
The application of Katrili is straightforward: it is mixed with water and then irrigated into the soil at calibrated dosages. This ease of use makes it highly accessible for a wide range of farmers. Initial trials have demonstrated promising results across various staple commodities vital to Indonesia’s food supply, including tomatoes, beans, shallots, and rice. These early successes validate the scientific premise and practical applicability of the booster, paving the way for broader adoption. The utilization of waste products like shrimp and crab shells to extract chitosan aligns perfectly with the principles of the circular economy, transforming what would typically be discarded into a valuable agricultural input. This not only reduces waste but also provides an economically viable and environmentally sound alternative to synthetic fertilizers.
