Surakarta, November 26, 2025 — The novel planting medium BIOMETAM was showcased at the BIOCHAMP 2025 event in Building F Hall, Faculty of Teacher Training and Education (FKIP), Universitas Sebelas Maret, Surakarta. At this expo, the BIOMETAM team unveiled an environmentally sustainable planting medium made from coconut trash, positioning it as a viable, cost-effective, and high-value option for sustainable agriculture to the student audience. At the outset of the event, the BIOMETAM booth attracted considerable attention from attendees across multiple departments who were keen to understand the product’s creation and implementation.

BIOMETAM’s innovation fundamentally resides in its astute reutilization of coconut husks and shells, which are transformed into cocopeat and biochar. The two components are amalgamated into a singular, ready-to-utilize medium appropriate for diverse horticultural and ornamental plants. This formulation presents a unique market advantage, as the combination of cocopeat and biochar delivers enhanced water retention, excellent aeration, and stable carbon content that promotes plant growth more effectively than conventional raw materials. This differentiates BIOMETAM from other traditional products that are frequently marketed as raw materials devoid of supplementary nutrients.
Innovation encompasses the product’s packaging, which boasts a distinctive cylinder form. This wrapper is designed to be opened and converted into a functional polybag, so minimising plastic waste and ensuring the packaging has a secondary use instead of being promptly tossed. This design decision underscores BIOMETAM’s dedication to a “zero-waste” mentality, in harmony with international initiatives aimed at fostering environmental preservation through more intelligent product lifecycles.
The demonstration had significant interaction, with interactive discussions centred on the technical manufacturing of biochar, the medium’s durability, and its potential as a green business opportunity. Students and instructors commended the idea for its capacity to convert agricultural waste into a commercially viable product while mitigating environmental degradation. BIOMETAM’s involvement in BIOCHAMP 2025 is a crucial initiative to enhance academic understanding of sustainable resource management and the significance of leveraging local resources to address contemporary agricultural issues.
