Descripción del proyecto
La recuperación orgánica deviene posible para las plantas pequeñas
El digestato, el material restante tras la digestión anaerobia de la materia prima biodegradable, se utiliza principalmente para mejorar las cualidades físicas del suelo. Sin embargo, en la actualidad, las limitaciones, como la falta de un equipo rentable disponible, impiden que las plantas pequeñas conviertan el digestato en productos biofertilizantes. El proyecto NOMAD, financiado con fondos europeos, tiene como objetivo superar este obstáculo mediante el desarrollo de una solución tecnológica novedosa a pequeña escala que recuperará la fibra y los nutrientes específicos del digestato. Así, estos nutrientes pueden utilizase para formular productos biofertilizantes de alto rendimiento. Dadas la movilidad y la modularidad de la solución, podría servir en múltiples plantas y dar como resultado unos gastos compartidos que podrían hacer que fuera más viable que instalar sistemas en cada planta.
Objetivo
NOMAD gathers partners from China, Greece, the UK, Italy, Romania, Malta and the Netherlands to develop an innovative, small-scale tech solution designed to recover fibre and specific nutrients from digestate for formulation into high performance bio-fertiliser products. It addresses key digestate issues including environmental and health risks, handling, variable composition and the increasing volume being produced. Currently, turning digestate into bio-fertiliser products is not feasible for most small plants due to lack of available, cost-effective equipment, and the expense of achieving end of waste standard PAS110.
Building on partners’ previous work, the proposed technology will utilise heat from combustion of waste timber and recovered energy from a collection vehicle to improve energy efficiency while simultaneously addressing regulatory compliance. Specific nutrients will be extracted from the liquid fraction and water recovered for reuse. The remaining sludge will be blended & composted with ash (derived from waste timber combustion) and biochar to produce optimised, nutrient-balanced soil conditioners. The model rests on the solution’s mobility and modularity as one unit could serve multiple plants, tackling digestate from a range of feedstocks with shared costs making it more viable than installing systems at individual plants.
Other project activities include stakeholder engagement; field trials across contrasting regions; policy recommendations; a comprehensive impact assessment of the business model; and dissemination of key outputs. The project aims to replace non-renewable mineral fertilisers with low-carbon, organic equivalents; minimise environmental and health risks associated with digestate; create a new, disruptive business model for rural decentralised AD; and achieve a more favourable climate for circular economy development through successful stakeholder engagement.
