In July 2019, the EU Fertilisers Regulation was published with the objective of placing secondary raw materials on the EU fertiliser market in order to protect primary raw materials. It aims to enable recycled organic fertilisers and soil improvers (composts and digestate products) access to the EU internal market so that they can compete on an equal level with mineral fertilisers.
The main objectives were:
- Boosting organic matter (biowaste) recycling from biowaste
- Integration of organic fertilising products into the scope of the NFR
- Introducing harmonised EU rules for products diverting from organic waste materials
- Creating access to CE marking and free trade for organic fertilising products across EU
The regulation defines in Annex II a list of component material categories (CMC), of which compost is CMC 3 and non-energy crop digestate is CMC 5. Specific labelling requirements are also set out for product function categories (PFC), which are subdivided into fertilizers, soil improvers, growing media, liming materials and biostimulants.
Manufacturers of these product groups have to demonstrate that their products comply with environmental and health requirements (limit values for physical and chemical contaminants) in order to display the CE mark on their products. In addition, compost and digestate products manufactured from waste must be subject to external quality control, which is recognized by each member state through a conformity assessment.
In order to avoid creating additional barriers to the marketing of established secondary raw materials in national markets, the regulation foresees an ‘optional harmonisation’. This means that compost and digestate manufacturers can decide whether to label their products with the CE mark: they can either freely trade their CE-marked products on the internal market
in accordance with common European rules, or simply market their
non-CE marked products according to national rules.
The regulation sets out criteria covering safety, quality and labelling that all fertilising products must meet so that they can be freely traded throughout the EU. In addition, quality requirements for specific raw materials for the production of fertilisers, soil improvers and growing media are specified in the annexes.
For compost and digestate products, these specific requirements are based on the JRC Report 2014 (End of Waste Criteria for Biodegradable Waste Subjected to Biological Treatment). In addition to requirements covering the production process and product quality, only separately collected organic waste is permitted as input materials for composting and anaerobic digestion.
For the component materials ‘compost’ and ‘digestate’ only specific input materials are allowed and specific process requirements for composting and anaerobic digestion are described. As suitable input materials source separated bio-waste, incl. ABP category 2 and 3 materials and residues from food processing industries can be used. Excluded as input materials are sewage sludge and mixed municipal waste.
The general process requirements are comparable to the process requirements laid down in the ECN–QAS and in several national quality assurance schemes.
For all animal by-product input material, like catering waste, the EU Fertiliser Regulation recognises only the ABP transformation standard of 70 °C for at least 1 hour at a maximum particle size 12 mm, which is not suitable for composting.
Therefore, the European Compost Network submitted an application on new European transformation parameters for composting animal by-products to the European Food and Safety Authority (EFSA). If alternative methods will not be adopted, it is unlikely that any compost or digestate including kitchen waste will be placed as CE marked fertilising product on the European market.
The final fertilising products can be placed on the market according to a specific conformity assessment procedure. If compost (CMC3) or digestate (CMC5) from waste materials are used in an organic fertiliser, solid improver or growing media an external conformity assessment, including process and product control by a notified body will be obligatory.
