How the Bio-Circular EconomyIs Changing the Rules

For most of the twentieth century, the dominant logic of agriculture and industry followed a single, unquestioned sequence: extract, produce, consume, discard. Raw materials were pulled from the earth, transformed into goods, used, and then thrown away. Waste was an afterthought, a cost to be minimised or quietly buried. The system functioned, at least for those who could afford to overlook its consequences. But those consequences accumulated over decades: degraded soils, polluted waterways, rising emissions, and a food system that feeds the world while steadily undermining the natural cycles it depends upon.

A fundamental shift is now underway. The bio-circular economy represents a rewriting of the rules that govern how Europe produces food, manages biological resources, and thinks about what we call waste. Understanding this shift is not a matter of idealism. It is a practical concern for anyone operating in the agrifood sector today.

The bio-circular economy is not a future scenario. It is already a measurable economic reality.

The EU bioeconomy currently generates approximately 2.7 trillion euros in annual value added and supports an estimated 60 to 62 million jobs across agriculture, forestry, fisheries, food processing, bio-based chemicals, and energy. This makes it one of the largest economic domains in Europe. The European Commission’s Strategic Framework for a Competitive and Sustainable EU Bioeconomy, adopted in November 2025, projects this figure reaching 7 trillion euros by 2030 as bio-based industries scale and integrate more fully into European value chains.

In the biogas and biomethane sector, the pace of change has been substantial. Europe closed 2024 with 1,620 biomethane-producing facilities across 25 countries, 111 more than the previous year. Combined biogas and biomethane production reached 22 billion cubic metres, equivalent to the total inland gas demand of Belgium, Denmark, and Ireland together. Private investment committed to biomethane development ahead of 2030 already stands at 28.4 billion euros.

The anaerobic digestion market, which converts organic waste into both energy and nutrient-rich digestate, was valued at 58 billion US dollars in Europe in 2024 and is projected to grow at 4.3% annually through 2034. Europe generated 25 million tonnes of digestate in 2024 alone. Current biogas production already supplies organic nitrogen equivalent to 17% of the EU’s nitrogen fertiliser demand, at a time when the EU imported 24.2 million tonnes of synthetic fertilisers.

The linear economy follows a simple sequence: take, make, use, discard. The bio-circular economy transforms that sequence into a loop. What leaves one process becomes the input for another. Agricultural residues, crop stalks, manure, food processing by-products, are not problems to dispose of. They are resources to be redirected.

Consider a farm operating within circular logic. Organic waste from the harvest is composted and returned to the soil, reducing the need for synthetic chemical inputs. Animal manure feeds a biogas unit that generates heat and electricity for the farm. The digestate from that process fertilises the next crop. Every output becomes an input somewhere in the system.

Agricultural residues already represent 45.4% of all European biogas plant feedstock. Germany alone operates over 9,500 biogas plants generating 10 billion kilowatt-hours of electricity annually. Denmark has integrated the model deeply enough that its plants now process food and agricultural waste, recycle nutrients back to fields, and are piloting the use of captured biogenic CO₂ for e-fuels and carbon storage. These are not isolated experiments. They are functioning components of a national economy.

The bio-circular economy is not only changing how farms operate. It is reshaping the broader regulatory and economic framework within which they compete.

The European Green Deal and Farm to Fork Strategy set clear targets: a 50% reduction in chemical pesticide use, a 20% reduction in fertiliser use, and 25% of EU farmland under organic management by 2030. These have been reinforced by the November 2025 Bioeconomy Strategy and the forthcoming Circular Economy Act, which will establish a Single Market for secondary raw materials and aims to double Europe’s circularity rate to 24% by 2030. Horizon Europe has committed 10 billion euros specifically to food, bioeconomy, and agriculture research through 2027.

For producers, processors, and investors, the direction is clear. The regulatory and financial architecture of European agriculture is being redesigned around circular and bio-based principles. Subsidies, market access, and competitiveness will increasingly favour those who operate within circular logic. The bio-circular transition is no longer simply an environmental commitment. It is becoming a condition for remaining competitive in European markets.

Meeting these targets will require more than regulation. It will require adequate support structures, realistic timelines, and economic models that work at the farm level, not only in policy frameworks. Ambition and practicality need to move together.

More Than Technology: A Change in Economic Logic

Reducing the bio-circular economy to a set of technical solutions misses the deeper change taking place. Biogas plants, composting systems, precision fermentation, bio-based materials: these are instruments. The more significant transformation is economic. It concerns how value is defined, how resources are priced, and how the relationship between production and natural systems is understood.

In a linear economy, waste is an accounting cost to be minimised. In a circular bioeconomy, waste streams become potential revenue streams. A tonne of organic waste carries value as biogas, as compost, as biofertiliser, or as feedstock for bio-based plastics. The farm that manages manure as a resource rather than a liability captures that value. The region that builds infrastructure to aggregate and process agricultural residues generates new economic activity from materials previously discarded.

This shift also changes who can participate meaningfully. Smaller farms, rural communities, and regions that have long sat on the periphery of industrial food systems hold genuine assets in a bio-circular model: land, organic resources, local knowledge, and proximity to natural biological cycles. The circular bioeconomy has a structural tendency toward decentralisation, distributing value creation across territories rather than concentrating it in large industrial nodes.

Europe generates 286.4 million tonnes of crop residues and 14.4 million tonnes of animal manure annually, most of it still underutilised within circular frameworks. Approximately 8 to 10 million tonnes of food and garden waste are currently lost within mixed waste streams, never reaching composting or anaerobic digestion. The EU Urban Waste Management Directive requires 65% municipal waste recycling by 2035; current performance in many member states falls well short of this target.

Closing these gaps is not primarily a question of technology. The technologies are available. It is a question of infrastructure, incentive, and connection. Three areas stand out as particularly important:

Regional aggregation and processing infrastructure. Individual farms rarely reach the scale needed to justify standalone biogas or composting facilities. Shared anaerobic digestion plants, composting hubs, and bio-waste collection networks allow the circular model to reach the threshold at which it becomes economically viable.

Stable markets for bio-based outputs. Digestate, compost, bio-based fertilisers, and biopolymers require consistent demand and clear pricing frameworks. Public procurement policies that prioritise bio-based products, alongside certification schemes that distinguish quality bio-inputs from conventional alternatives, are essential to making the circular value chain commercially sustainable.

Knowledge transfer and business model development. A significant share of adoption barriers are informational rather than technical. Farmers need accessible tools to evaluate the economics of bio-circular investments. Municipalities need practical frameworks for bio-waste collection. Entrepreneurs need networks that connect their innovations to markets. Structured mentoring, cross-border exchange of experience, and targeted support for SMEs working in this space are among the most effective levers available.

The Role of AGRI-BIOCIRCULAR-HUB

The transition described in this essay does not happen through policy alone. It requires concrete action at the regional level, connecting researchers, businesses, public institutions, and farmers within ecosystems capable of turning knowledge into practice. This is precisely the work that the AGRI-BIOCIRCULAR-HUB project is designed to support.

Funded under Horizon Europe and coordinated by Lviv Polytechnic National University, the project brings together partners from Poland, Latvia, Ukraine, Belgium, and Spain to build regional excellence hubs in smart agriculture and circular bioeconomy. It focuses on three countries where the bio-circular transition holds particular economic and strategic significance: Poland, Latvia, and Ukraine.

In Poland, the ecosystem is led by Poznan University of Life Sciences, which hosts one of Europe’s largest composting and biogas laboratories, alongside industry partners working on organic waste processing and sustainable materials. In Latvia, the Agroresursi un Economics Institute coordinates a pilot centred on poultry-based biogas and deep-tech commercialisation, with support from national innovation agencies and the Latvian Biogas Association. In Ukraine, Lviv Polytechnic leads regional work on circular waste management and bio-based innovation strategy, in partnership with municipal enterprises, regional administration, and civil society organisations.

Across all three ecosystems, the project operates through the same mechanisms that the evidence identifies as decisive: building shared infrastructure knowledge, developing business cases for circular technologies, supporting SMEs through mentoring and access to cascade funding, and facilitating cross-border exchange of experience between regions at different stages of the transition.

The project also addresses a structural gap that holds back bio-circular development in many European regions: the distance between what research institutions know, what entrepreneurs can build, and what farmers and municipalities are prepared to adopt. Bridging that gap through structured cooperation is, in practical terms, how the new rules get implemented on the ground.

AGRI-BIOCIRCULAR-HUB is one contribution to a much larger European effort. But it represents the kind of contribution that matters: regional, concrete, and oriented toward the networks and capacities that allow a transition of this scale to take root.
