Biowaste Management in Europe: Comparative Insights from Finland, France, and Italy

The EU Policy Framework for Biowaste Management

Biowaste management is a key element of the European Union’s sustainability agenda, aimed at reducing greenhouse gas (GHG) emissions, improving resource efficiency, and transitioning to a circular economy. The EU Green Paper on Biowaste Management [1] outlines three central goals for member states: separate collection, landfill diversion, and biological treatment. These objectives address the dual challenges of managing waste sustainably and protecting the environment.

Separate collection is essential for the high-quality processing of biowaste into compost and biogas, enabling its use in agriculture and renewable energy generation [2]. However, effective implementation requires substantial public engagement and infrastructure investment. Landfill diversion focuses on mitigating methane emissions from decomposing organic waste, which contribute significantly to climate change. The EU Waste Framework Directive mandates the progressive reduction of biodegradable waste in landfills, promoting alternative treatment methods. Biological treatment, including anaerobic digestion (AD) and composting, facilitates nutrient recycling and renewable energy production, supporting the EU’s circular economy objectives.

Visby, the historically rich capital of Gotland, Sweden, stands as a remarkable example of how heritage and sustainability can be harmoniously integrated [1]. My recent visit to attend the EUSBSR Annual Forum 2024 provided an opportunity not only to engage with leading experts on regional sustainability but also to observe firsthand how Visby balances its medieval heritage with contemporary environmental practices. This reflection captures the multifaceted approaches of Visby and Gotland to managing tourism, conserving biodiversity, and addressing water resilience.

Situating the discourse of recycled nutrient fertilizers in circular economy principles for sustainable agriculture

The article explores the multifaceted discourse surrounding recycled nutrient fertilizers (RNFs), examining their technological, environmental, economic, and policy-related dimensions. It highlights how stakeholders’ perceptions and the influence of public and farmer acceptance shape the adoption of RNFs, alongside the critical impact of regulatory and policy frameworks on their implementation.

At the end of October, I had the opportunity to attend the 15th Annual Forum of the EU Strategy for the Baltic Sea Region (EUSBSR) in Visby, Gotland. This year’s forum brought together over 500 stakeholders, including policymakers, industry representatives, and researchers, all focused on advancing the sustainability, resilience, and security of the Baltic Sea Region. Set against the historical backdrop of Visby, with its UNESCO-recognized medieval architecture, the forum provided both an inspiring and ideal setting for discussing sustainable regional development.

As co-lead for the EU Interreg BSR core project CiNURGi, my goal was to showcase our work on developing a circular economy for nutrients in the region. CiNURGi is an EU Interreg BSR core project dedicated to enhancing nutrient recovery from various resource streams, including agricultural, municipal, and industrial sources. By upgrading current infrastructure and technology, we aim to increase nutrient recovery efficiency and promote the adoption of recycled fertilizer products. In a region facing significant environmental challenges due to nutrient leakage and eutrophication, CiNURGi’s mission aligns well with the EUSBSR’s broader goals of sustainability and environmental protection.

Reflecting on the Nordic Biogas Conference 2024: Championing Circular Economy and Nutrient Recovery

This past October, I had the privilege of participating as a plenary speaker at the Nordic Biogas Conference (NBC) 2024 in Aalborg, Denmark. The NBC is a key platform for knowledge exchange and networking among experts, innovators, and stakeholders in the biogas and circular economy sectors. Organized by leaders from the biogas industries of all five Nordic countries, NBC 2024 brought together a diverse group of professionals dedicated to advancing sustainable energy and waste management solutions.

A Focus on Circular Economy, Waste Management, and Nutrient Recovery

During the session, titled Circular Economy – Waste Management – Feedstock and Fertiliser Quality, moderated by Linn Andersson from Avfall Sverige, I presented insights from the EU Interreg BSR core project, CiNURGi, where we focus on nutrient recovery as a catalyst for sustainable synergies across various sectors in the Baltic Sea Region. My presentation, Circular Solutions for Nutrient Recovery: Building Sustainable Synergies Across Sectors in the Baltic Sea Region [PDF], highlighted innovative solutions for recycling nutrient-rich biomass, developing industry standards for safe fertilizers, and fostering cross-sector collaborations. These approaches are essential for creating resilient, circular systems that reduce environmental impact while opening new economic opportunities.

Advancing the Discourse on Recycled Nutrients: Integrating Sustainable Practices into the Circular Economy

Introduction

The growing discourse on recycled nutrients (RNs) in organic farming is influenced by several key factors. Nutrient deficits, particularly of phosphorus (P) and potassium (K), are a significant challenge in organic farming, as biological nitrogen (N) fixation can only partly meet nitrogen demand, necessitating the replenishment of other nutrients through external inputs. Yet the uptake and use of RNs remains challenging. Concerns about contaminants, such as potentially toxic elements (PTEs), microplastics, and antibiotic resistance genes, create doubts among organic farmers regarding the safety and health impacts on soil and crops. Although some contaminants are declining, and soils show resilience in degrading or stabilizing pollutants, uncertainties persist.

The integration of nutrient recycling within the broader circular economy framework aligns with organic farming principles, promoting the reuse of societal waste streams to reduce reliance on finite mineral resources and minimize environmental impacts. However, acceptance of such practices remains debated within the organic sector. Economic feasibility and policy support are crucial, as cost-benefit analyses highlight the varying viability of different ecotechnologies. Technologies like anaerobic digestion of agricultural wastes are more economically viable compared to those in the wastewater sector, which require significant investments. Effective implementation depends on aligning economic and policy incentives with sustainability goals.

Public perception and stakeholder involvement also play a critical role, as participatory decision-making processes address local concerns and improve the legitimacy of implementing new ecotechnologies. Addressing stakeholders’ concerns about health risks, environmental pollution, and technical reliability is essential for broader acceptance. These factors collectively shape the ongoing discussion on the use of RNs in organic farming, balancing the benefits of nutrient recycling with the challenges posed by contamination, economic viability, and public acceptance.

In this article, a brief literature review is conducted to place the current discourse and concerns regarding RNs and nutrient recycling practices within the broader context of the circular economy, aiming to investigate how the uptake of RNs can be more effectively addressed.

Using 9 journal articles [1-9] as example studies of the field, this article begins by tracing the historical context and use of term “recycled nutrients”. It examines the various technological, environmental, economic, and policy-related dimensions of nutrient recycling, and illustrates how the practice of nutrient recycling can become an integral part of the circular economy.
