Biowaste recycling: here’s what you need to know

Biowaste accounts for 30–50% of Europe’s municipal solid waste, making it a major stream with untapped potential. While in the past much of this biodegradable waste ended up in landfills or incinerators, the EU’s growing focus on sustainability has placed biowaste at the core of circular economy strategies. Properly managed, biowaste offers multiple benefits: it can be transformed into compost or renewable energy, reduce greenhouse gas emissions, and help restore degraded soils across Europe.

Yet, despite the potential, the continent still faces challenges: uneven infrastructure, fragmented policies, and insufficient public engagement. Understanding how biowaste is managed and recycled—and what lies ahead—is critical for businesses, municipalities, and industries aiming to comply with regulations and harness the opportunities in this evolving sector.

Legal framework: EU policies driving biowaste recycling

Waste Framework Directive (2008/98/EC)

This foundational EU directive introduced the waste hierarchy, placing recycling above disposal. It mandates separate biowaste collection across all Member States starting January 1, 2024, and favors composting and anaerobic digestion (AD) over landfill or incineration.

Circular Economy Action Plan

Building on climate goals and the UN Sustainable Development Goals (SDGs), this plan targets a 50% reduction in food waste by 2030. It emphasizes biowaste as a vehicle for nutrient recovery and soil health restoration, promoting outputs like compost and digestate as replacements for synthetic fertilizers.

How biowaste is recycled: main processing methods

Composting (Aerobic Decomposition)

Used extensively in countries like Italy, Austria, and Germany, composting breaks down organic material in oxygen-rich conditions to produce a stable, soil-enriching compost. This method is well-suited for community-level or industrial-scale operations, depending on local infrastructure.

High-quality compost requires clean feedstock—which means low contamination from plastics and non-organics. When quality is ensured, compost is widely used in agriculture, landscaping, and land rehabilitation.

Anaerobic digestion (AD)

Ideal when energy recovery is a goal, AD processes organic material in the absence of oxygen, yielding biogas (usable as fuel or converted to biomethane) and digestate, a nutrient-rich fertilizer. Northern European countries, especially the Nordics, lean heavily on AD due to its dual energy and recycling benefits.

Mechanical-biological treatment (MBT)

Used where separate collection is incomplete, MBT systems attempt to recover biowaste from mixed municipal waste. However, they generate lower quality compost or digestate due to high contamination, making them a fallback option, not a best practice.

Biowaste recycling – performance examples by country

Across Europe, biowaste recycling performance varies widely by country. Austria and Germany lead the way with high collection rates supported by well-developed composting and anaerobic digestion (AD) infrastructure. Italy has seen rapid growth in both AD and composting facilities, reflecting a strong national push toward circular waste practices. France shows moderate progress—its infrastructure is expanding, and the country has set ambitious policy goals, but implementation still lags behind the frontrunners.

In contrast, Poland and much of Southern Europe continue to struggle with uneven collection systems and limited treatment capacity, hindering large-scale biowaste recovery. Meanwhile, Nordic countries boast advanced AD technology and efficient processing systems, although the use of composted material in agriculture remains less common compared to their Central European counterparts.

Challenges facing the biowaste sector

Despite legal backing and technological advances, several barriers limit the scalability and efficiency of biowaste recycling:

• Infrastructure gaps: Eastern and Southern Europe often lack composting and AD facilities, hampering progress despite legal mandates.
• Policy fragmentation: Different standards for compost and digestate usage across Member States hinder cross-border markets and investment.
• High operational costs: Separate collection, feedstock sorting, and contamination control demand significant investment.
• Plastic contamination: Still a leading cause of low-quality outputs; overcoming this requires both technological filtering and citizen education.
• Public awareness: Participation in biowaste separation is inconsistent. National campaigns and digital solutions (smart bins, traceability apps) are starting to address this.

Innovation and market trends in biowaste recycling

• Smart collection: Technologies like weight-based billing, contamination detection, and app-based tracking are enhancing efficiency.
• Biorefineries: Converting biowaste into bio-based chemicals and bioplastics represents a promising frontier.
• Soil health legislation (upcoming): Will likely mandate compost use in degraded soils, increasing demand and improving market conditions.
