Bio-based technological innovations enhancement in the management of organic almond sector
About this good practice
In Sicily, a business-led initiative tackled the high volume of waste from almond processing, especially shells and skin, which typically form two-thirds of almond fruit. Recognising the hidden value in these by-products, a consortium comprising some stakeholders led industrial research to create sustainable reuse models. The project focused on three innovative streams: a) Compost production by combining almond shells with manure and grape residues. This organic compost demonstrated high effectiveness in nurseries and almond groves; b) Construction materials using ground almond shells mixed with gypsum, producing eco-certified blocks with good mechanical and environmental performance; c) Nutraceutical enhancement of baked goods through the inclusion of antioxidant-rich almond skin, with successful market and sensory tests. The project shows how agri-waste can be transformed into high-value products across sectors, agriculture, construction, and food, generating new income opportunities and reducing environmental impact. The project was implemented in line with the regional research strategy, in collaboration with regional officials. The project team worked with the region to implement the results, as well as developing the integrated dried fruit supply chain projects put out to tender under RDP 2014/2022. The model supports policy goals for circular economy, agri-food innovation, and rural development.

Evidence of success
The practice led to marketable compost and food products, certified construction materials, and new business opportunities. Market-ready compost and bakery products were launched; certified building blocks were developed. The initiative reduced almond waste and expanded local value chains.
Potential for learning or transfer
This practice demonstrates how local agricultural waste can fuel circular business models, inspiring public authorities to foster similar initiatives. It highlights the role of research-industry partnerships in turning residues into economic opportunities. Local and regional governments can replicate or support this model by integrating it into rural development plans, agri-innovation funds, or climate resilience strategies. The approach is easily adaptable to other crops or sectors (e.g., wine, citrus), and scalable through cooperation with universities or innovation hubs. By supporting regulatory frameworks for sustainable materials, certification processes, or targeted subsidies, authorities can drive local green jobs, reduce waste costs, and diversify rural economies. The experience also supports policy learning on cross-sectoral innovation, linking food, farming, and construction, within the wider goals of the Green Deal and the EU bioeconomy strategy.
