ESPP has submitted, to the European Commission, proposed quality and safety criteria for (a) use of biomass ashes as a fertiliser or (b) as a raw material in fertiliser production. The proposed criteria, elaborated after concertation with ESPP members and partners, covers sewage sludge incineration ash (SSIA), poultry litter combustion ash, biomass energy ash, meat and bone meal ash (MBMA) and specific industry sector biomass ashes, in total over 600 000 tonnes P/year. Consideration. ESPP already proposed criteria for recovered struvite as a fertiliser, which have been transmitted to the EU’s JRC (Joint Research Centre) for consideration in the process of developing EU criteria with the objective of implementation in the EU Fertiliser Regulation revision (criteria for future CE label). The proposed criteria for ash cover input materials, combustion conditions, possible contaminants (heavy metals, dioxins …) and agronomic value of the ash. The document notes that poultry litter combustion ash and MBMA are already proven and used as fertilisers in Europe. ESPP welcomes comments on the proposed criteria.
