SSOIL: Turning Agri-Food Waste into Functional Compost-Like Materials

  • by

Project Name: Valorisation of agri-food residues as functionalised compost-like material
Acronym: SSOIL
Participating Companies: AERIS Tecnologías Ambientales S.L. (Lead SME), Jopo Sa Canoval S.L. (Partner SME)
Funding Program: CESAM Cascade Funding – Open Innovation Projects

The SSOIL project aims to strengthen sustainability in the agri-food sector by developing a compact, on-site solid-state fermentation (SSF) unit to transform agri-food residues—including pruning waste—into functional compost-like material. By combining raw and nutrient-enriched wood, the process produces a soil input rich in macronutrients, organic carbon, and biostimulant properties. The solution will be validated agronomically, while strategic IP and exploitation actions will support market readiness. With key partnerships including LEITAT, UAB, and CLIQIB, SSOIL integrates strong innovation, local knowledge, and user alignment.

Project Goals:

  • Design a compact, low-energy SSF unit for agri-food waste valorisation.

  • Produce high-quality compost-like material tailored with N, P, organic matter, and biostimulants.

  • Perform agronomic tests to validate effectiveness and soil health impact.

  • Promote regenerative agriculture by improving soil fertility and reducing chemical inputs.

  • Support commercial adoption through exploitation plans and technology transfer.

Interregional Collaboration & Impact:

SSOIL connects Catalonia and the Balearic Islands through a collaboration between AERIS and Jopo Sa Canoval. Technology developed in Catalonia will be tested and applied in the Balearics, acting as a demonstration for other farmers in the region. Workshops and local engagement activities will showcase results and support replication. Involvement of CLIQIB and Leitat enhances outreach and strengthens interregional knowledge exchange, paving the way for future commercialization and adoption.

Circularity at the Core:

The project brings circular economy principles to life by transforming local agricultural waste into valuable soil enhancers. AERIS expands its portfolio with a microbiology-integrated SSF system, while Sa Canova reduces costs and reliance on synthetic inputs. The resulting compost-like material improves soil health and nutrient cycling, supporting climate resilience and low-impact farming practices. SSOIL contributes directly to reducing the carbon footprint of waste management and fertilizer use—key goals of Europe’s Green Deal and bioeconomy agenda.
