The Waste Agency allocates 4.5 million for organic collection vehicles (up to 90% funding, maximum €200,000 per vehicle), 5 million for recycling centers, and 3 million for recycled aggregates. Circular economy projects receive up to 75% funding for SMEs.

Andalusia has allocated 61 million euros from Next Generation EU funds for bio-waste treatment, resulting in 68 grants for 20 million in improved separate collection and 14 grants for 22.7 million for facility construction. Additional programs include 10 million for collection vehicles and 700,000 euros for local circular economy plans.

Galicia offers 9.2 million euros in non-competitive regime throughout 2025, financing up to 90% in three lines: separate collection of bio-waste, home and community composting, and collection of used oils. Valencia implements lines for new separate collections especially for bio-waste, construction of treatment facilities, and collection of oils and textiles.

Extremadura structures four support lines: door-to-door collection (90% funding, maximum €742,500 per municipality), collection in closed containers, composters for municipalities with fewer than 1,000 inhabitants, and construction of recycling centers, with completion scheduled for March 31, 2026.

Fundable projects: from composting to digitalization

The biogas composting financing programs cover a complete technological spectrum that reflects the sector's maturity and innovation opportunities.

Composting technologies include advanced aerobic systems with automated monitoring, container composting for controlled processing, community initiatives with social participation components, smart technologies incorporating IoT sensors and AI optimization, and regional networks connecting multiple waste sources.

Biogas production encompasses anaerobic digestion facilities for energy recovery, co-digestion systems processing multiple organic waste streams, biogas upgrading to biomethane for grid injection, decentralized small-scale biogas for rural communities, and industrial biogas from food processing waste.

Biofertilizer development comprises nutrient recovery technologies extracting N, P, K from organic waste, production of liquid fertilizers from digestate processing, specialized biofertilizers for specific crop applications, integrated biorefineries producing multiple products, and integration with precision agriculture.

Digitalization includes AI-powered sorting systems, blockchain traceability for waste-to-product chains, digital platforms connecting producers with processors, IoT systems for collection optimization, and data analytics for flow optimization.
