Sewage Sludge in Agricultural Lands. The Legislative Framework in EU-28
Summary
This review examines the legislative framework across EU member states for using sewage sludge as agricultural fertilizer. While sludge provides valuable nutrients and organic matter, researchers found it can also contain contaminants including microplastics, heavy metals, and pathogens. The study highlights the need for updated regulations that account for emerging pollutants like microplastics to better protect soil health and food safety.
Incorporating sewage sludge (SS) into soils presents a cost-effective and environmentally friendly option compared to conventional farming practices. However, SS could be perceived as a double-edged sword, as it may contain a broad spectrum of contaminants, posing threats to soil, underground waters, food chains and human health. Even from an epidemiology perspective, the COVID-19 pandemic has instigated debates regarding the potential health risks associated with SS. The handling of SS is emerging as a significant issue in the European Union (EU), primarily due to its increasing utilization and the presence of contaminants such as heavy metals (HMs), microplastics (MPs), Pharmaceuticals in the Environment (PIE), and personal care products (PSPs). The Council Directive 86/278/EEC governs the limits of HMs when SS is utilized in agriculture. However, the Directive is enacted diversely throughout EU member states (MS), with their national legislations highlighting differences, gaps and various approaches in implementing the Council Directive. The Directive, which has been in force since 1986, has not undergone any significant revisions until the recent disclosure of a revised version in May 2023. The executive summary of the evaluation of the Council Directive 86/278/EEC (SWD-2023) – {final 158} specifies maximum concentrations of six HMs in SS among its regulatory measures. This article delves into capturing the current legal framework that defines and delimits the processes and obligations of EU MS regarding SS's management, treatment, and agriculture amendment. The primary objective is to explore the qualitative and quantitative differences/discrepancies between the MS National legislation and point out discontinuities and gaps, thus setting forward a cohesive step for future revisions and updates of the relevant legislation. Part of the article's results reflect the different approaches to permissible limits of HMs concentrations in the EU MS and between international organizations such as the Food and Agriculture Organization (FAO) and the World Health Organization (WHO). Moreover, the total absence of MPs and other Common Soil Pollutants (antibiotics, pharmaceuticals, etc.) limit values are evidence of the gaps in the current legislative framework.

Sewage Sludge in Agricultural Lands: The Legislative Framework in EU-28
This study examines how European Union member states regulate the use of sewage sludge in agriculture, finding significant inconsistencies in permissible heavy metal limits and a near-total absence of regulations for emerging contaminants like microplastics and pharmaceuticals. The core EU directive governing sewage sludge application has not been substantially updated since 1986. The findings highlight a critical need for harmonized, modernized regulations to protect soil health and food safety across Europe.
Agricultural Use of Sewage Sludge as a Threat of Microplastic (MP) Spread in the Environment and the Role of Governance
This study examines how agricultural use of sewage sludge introduces large amounts of microplastics into soil ecosystems. The researchers propose a multi-stakeholder governance strategy for the European Union that balances the benefits of sludge as fertilizer against microplastic contamination, recommending stricter regulations on sludge quality including limits on microplastic content.
Land Application of Biosolids in Europe: Possibilities, Con-Straints and Future Perspectives
This review examines how sewage sludge, or biosolids, is used as agricultural fertilizer across European countries and the regulations governing this practice. While biosolids provide valuable nutrients like phosphorus, the study highlights concerns about contaminants including microplastics, pharmaceuticals, and heavy metals that could enter soil and food chains through land application.
Microplastic contamination in sewage sludge: Abundance, characteristics, and impacts on the environment and human health
This review focuses on microplastics found in sewage sludge, which is often spread on agricultural land as fertilizer. The practice introduces microplastics directly into farm soil, where they can be taken up by crops or leach into groundwater. This creates a pathway for microplastics to reach human food and drinking water, raising concerns about the safety of using sewage sludge in agriculture.
Arıtma Çamurlarının Tarımsal Amaçlı Kullanımı:Türkiye’de ve AB Ülkelerinde Yasal Durum
This Turkish-language review examines the legal frameworks in Turkey and EU countries governing the agricultural use of sewage sludge. Sewage sludge applied to farmland is a known pathway for microplastics to enter agricultural soils, making this regulatory review relevant to understanding how sludge management policies affect microplastic contamination of food-producing land.
