How trust and knowledge are transforming agricultural waste into clean energy in Hungary's rural communities
In the picturesque but often struggling countryside of Hungary, a quiet revolution is taking shape—one that seeks to transform agricultural waste into clean, renewable energy. While the technical potential of biomass energy is vast, its success hinges on a factor far more complex than any machine: social acceptance. This article delves into groundbreaking research from the Koppány Valley, revealing how the hopes for a greener, more self-sufficient rural future depend not just on technology, but on winning the trust and understanding of the local communities who will power it.
Biomass is the largest source of renewable energy in the European Union, accounting for almost 60% of all renewable energy consumption.
Biomass energy harnesses organic material—from crop residues like straw and husks to dedicated energy crops and livestock waste—and converts it into power, typically through processes like combustion or anaerobic digestion to produce biogas.
Within the European Union, member states like Hungary have committed to increasing their share of renewable energy. The potential is particularly significant in its rural regions, which are rich in agricultural and forestry biomass 3 .
For rural areas, this represents a golden opportunity: it turns local agricultural by-products, often seen as waste, into a valuable resource that can generate electricity, provide heat, and create shorter, more resilient local energy supply chains 3 6 .
Utilizing these resources can be a cornerstone for achieving Sustainable Development Goal 7 (SDG7), which aims to ensure access to affordable, reliable, sustainable, and modern energy for all 6 . The challenge, however, lies in bridging the gap between this technical potential and the social reality on the ground.
To understand the human factors behind biomass energy adoption, researchers conducted an in-depth study in the Koppány Valley, a micro-region of ten settlements in South Transdanubia, Hungary. This area, characterized by significant natural resources but also by poor socioeconomic conditions and an aging population, had plans to build a community-owned biogas plant 3 .
In May 2018, researchers undertook a detailed survey of the local population, collecting 310 complete responses 3 . The aim was to move beyond simple "yes" or "no" questions and understand the nuanced factors influencing people's opinions.
Using a multinomial logistic regression model, the researchers analyzed how these factors influenced whether a person was a staunch supporter (YES), an opponent (NO), or was uncertain (MAYBE) about the proposed biogas plant 3 .

Identification of key factors influencing acceptance
The analysis yielded critical insights into the minds of the rural population. The results showed that acceptance was not a matter of chance but was strongly linked to specific, measurable characteristics.
| Factor | Impact on Acceptance | Key Finding |
|---|---|---|
| Knowledge & Education | Strong Positive Correlation | Higher general knowledge of biomass and specific technologies, along with a higher education level, significantly increased support. |
| Trust in Local Authorities | Critical | Trust in local organizations and decision-makers was a major determinant of public support. |
| Farming Activities | Moderate Influence | Involvement in plant cultivation or animal keeping (sources of biomass) had some positive effect. |
| Age & Gender | Less Significant | These demographic factors were not the primary drivers of acceptance or rejection. |
The study concluded that a lack of awareness and low levels of trust were significant social barriers. The research demonstrated that trust in local authorities was just as important as technical know-how. When citizens believed in the competence and integrity of their local leaders, they were more likely to support community-led energy projects 3 .
"Perhaps the most significant finding was the identification of a 'convincible middle'—the 'MAYBE' group. This uncertain segment of the population, which could be swayed toward support, held the key to unlocking the project's social potential." 3
Furthermore, the findings highlighted a "knowledge gap." General awareness of renewables was not enough; understanding specific technologies like biogas and biodiesel was a stronger predictor of support. This underscores the need for targeted public information campaigns that go beyond generalities and clearly explain how the technology works and what its local benefits are 3 .
| Research "Reagent" | Function |
|---|---|
| Structured Population Survey | Collect standardized, quantifiable data |
| Multinomial Logistic Regression | Predict probability of category membership |
| Likert Scale Questions | Measure intensity of agreement |
| Variance Inflation Factor (VIF) | Ensure model reliability |
| Group | Characteristics |
|---|---|
| Supporters (YES) | High education, knowledge, trust |
| Opposed (NO) | Low trust, low knowledge |
| Uncertain (MAYBE) | Moderate knowledge, open to info |
The implications of this research are profound for policymakers and community leaders. To successfully implement biomass energy projects in rural areas, a dual strategy is essential:
Local authorities and project developers must engage in open, continuous dialogue with the community. Building trust is a prerequisite for technological adoption 3 .
Information campaigns must be specific and practical. They should demystify technologies like biogas plants and clearly articulate the local economic and environmental benefits, such as shorter local energy value chains and improved energy security 6 .
Higher education, good knowledge of biomass tech, high trust in authorities.
Engage as community champions and advocates for the project.
Low trust in authorities, low knowledge levels, unlikely to change stance.
Focus on addressing specific, tangible concerns rather than broad persuasion.
Moderate knowledge and trust levels; open to information.
Target with clear, accessible information and opportunities for participatory decision-making.
Successful implementation of biomass energy projects in rural Hungary could:
The journey to a sustainable energy future is not paved by technological breakthroughs alone. The case of the Koppány Valley teaches us that the most sophisticated biogas plant will remain a blueprint if it is not rooted in the community it aims to serve. Social acceptance is the cornerstone of the renewable energy transition, especially in rural communities.
By investing in education, fostering trust, and thoughtfully engaging with the "convincible middle," we can unlock the vast social and biomass potential of the countryside, turning it into a powerhouse of sustainability and resilience for generations to come.
