Self-sufficient organic Finnish farm grows its own fuel and a greener future

An award-winning farm has teamed up with Helsinki University to create a symbiotic food production system that is self-sufficient in energy and nutrients. It’s a trailblazer in sustainable agriculture.

Organic Knehtilä Farm provides its own nutrients and energy, thanks to careful long-term planning and a small onsite biogas plant operated by energy utility Nivos.

The biogas powers his tractor, pickup truck and cars, and is available to others at a commercial filling station on the edge of the farm, although vehicles that can use biogas are still relatively rare. It offers a valuable alternative to meet the growing need for affordable, clean domestic energy.

Demand for organic food continues to grow. “The price gap between organic and standard production is narrowing, partly because we don’t need fertiliser. Our farm has its own product line of oat and buckwheat products, which are produced here using a proven cultivation method known as agroecological symbiosis, where nutrients and energy are efficiently recycled.”

The sprawling 380-hectare farm’s carefully balanced circular economy has developed over a decade and a half, earning a WWF award in 2015 as a model of nature-friendly agriculture. In 2021, the Finnish Organic Association chose Knehtilä for the honour of Organic Business of the Year.

“Biogas production can convert farms from being energy consumers to energy producers, and play an important role in the transition away from fossil fuels. When it’s done in a smart way, it’s also possible to increase biodiversity in farming systems.”

Knehtilä forms part of the Global Network of Lighthouse Farms, a project led by Wageningen University in the Netherlands, involving commercially viable farms that offer “radical solutions to address sustainability challenges.” International visitors frequently come to Knehtilä to learn about unique system.

The rich, vibrant cycle of life at Knehtilä is visible in not only the lush fields, but also in the insects and frogs that frequent them, and in a few animals such as horses, sheep, goats, chickens and rabbits. The farm is also a lively event venue; a high-ceilinged, 80-year-old barn has been converted to a space for up to 100 people for weddings, theatre performances and concerts.

The biogas produced in Kerala is primarily used for cooking and electricity generation. However, raw biogas contains impurities that reduce its energy efficiency and contribute to equipment corrosion and environmental pollution. Upgrading and purification enhance the usability of biogas, making it a cleaner and more versatile energy source.

Steps in Biogas Upgrading and Purification

Carbon Dioxide Removal: CO₂ is separated using techniques like water scrubbing, chemical absorption, or pressure swing adsorption to increase methane concentration.

Hydrogen Sulfide Removal: H₂S is removed using iron oxide filters, activated carbon, or biological desulfurization to prevent corrosion and toxic emissions.

Dehydration: Moisture is removed using drying agents or refrigeration to ensure the biogas is free of water vapor.

Compression: The purified biomethane is compressed for storage and transportation.

Applications of Upgraded Biogas in Kerala

Compressed Biogas (CBG): Used as a clean fuel for vehicles, reducing dependency on petrol and diesel.

Grid Injection: Upgraded biogas can be injected into natural gas pipelines to supplement conventional energy sources.

Industrial Use: Biomethane serves as a reliable energy source for Kerala’s industrial sector.

Export Potential: Purified biogas can open opportunities for energy export, boosting Kerala’s economy.

Economic and Environmental Benefits of Biogas Upgrading in Kerala

Energy Efficiency: Upgraded biogas has a higher calorific value, increasing its efficiency in energy production.

Cost Savings: Cleaner biogas reduces maintenance costs for equipment and extends their lifespan.

Reduction in Greenhouse Gas Emissions: Purified biogas burns cleaner, cutting down carbon emissions and contributing to Kerala’s fight against climate change.

Job Creation: Setting up upgrading and purification plants creates employment opportunities in technology, operations, and maintenance.

Challenges in Implementing Biogas Upgrading in Kerala

High Initial Investment: The cost of setting up upgrading plants can be a barrier for smaller biogas producers.

Lack of Awareness: Many biogas producers in Kerala are unaware of the benefits of purification technologies.

Technology Gaps: The availability of advanced purification technologies remains limited in some areas.

Policy and Regulation: Standardizing biogas upgrading requires robust government policies and incentives.

Government Initiatives and Support for Biogas in Kerala

The Kerala government is actively promoting biogas adoption through subsidies and training programs. Incorporating upgrading and purification into these initiatives will further enhance the efficiency and adoption of biogas in Kerala as a clean energy source.

Conclusion

Upgrading and purifying biogas in Kerala is a critical step toward a cleaner and more sustainable future. By transforming raw biogas into high-quality biomethane, Kerala can significantly improve energy efficiency, reduce environmental impact, and boost its renewable energy portfolio. With continued investment in technology, awareness, and policy support, biogas upgrading and purification can revolutionize the state’s green energy landscape.

A few months back I saw a clip from Mad Max:Beyond Thunderdome for the first time in decades and a light went off in my head. I don't have as many swine as they did in Bartertown but I don't need more than we already have to make biogas. Three hogs should shit enough to keep us supplied well enough.

I figure I can improve on the simple, single-barrel, "batch digester" design by equipping them with both drain fittings and agitators, and by using them in a battery array of multiple barrels going at once, in succession. It's been "indoor chores weather" lately so I've been keeping my brain busy with R&D on that. I think that with this system our pigs can provide us enough biogas to meet our needs. Now I have to run a test model and gather some data.

The instant I finished inking the first diagram I though of a far better way to do the agitator. Of course.
