Demeca farm biogas plant is an energy efficient, the finnish innovation and reliable choice.

Energy efficient Demeca farm -size biogas plant complete effective pre-treatment, which enables efficient and plentiful biogas production. Demeca biogas plants are made by modules and containers. Module biogas plant is easy to remove, transform, grow and sale. Demeca biogas plant is tested with a cold and difficult circumstances in Finland. Biogas production is an economical when you have enough liquid manures (slurry) and dry manures (grass, straw etc.). Biogas production is a significant advance on agriculture and cuts down greenhouse gases. Start bioenergy production with Demeca biogas plant and transfer your farm to biogas era.

Agricultural biogas plant

Demeca agricultural biogas plant is a finnish innovation.

Sales, planning, service and spare parts comes from Finland. You can get remote service wich is easy choice and helps you with daily control. Demeca service check your biogas plant notifications and fix problems with remote connection. Biodegradation® biogas plant has a finnish sertificate Key flag

“The biogas plant produces electricity and heat in to your farm. You can also make a new business by selling a biogas and biomethane”.

Biogas plant: How does it work?

Biodegradation® technology can use both manures: liquid manure (slurry) and dry manures (grass, straw etc.). The main manure is sludge and you can use the old dry manures wich are difficult to dispose. The manures pre-processed in the gFeed container unit. Careful pre-treatment enables efficient and plentiful biogas production.

The slurry from the barn is crushed to a smooth and fluid state with the Demeca Kaira slurry pump and pumped from the barn to the gMix container unit. Dry manures are easy to add through a crushing feeder from the outside to the gFeed container unit. Feeder opens using the remote control.  The feeder processes dry feed, increasing the specific area of plant parts, allowing for effective bacterial activity. Homogenization in biogas production means that wet and dry manures fed into the biogas process, which are processed into a finely dispersed mixture. Then finished feeds is pumped into a biogas reactor for digestion.

“The biogas process produce a better fertilise: less smell, fertilizer dissolves effective into plants and field, you don’t need to buy so much artificial fertilizer and machine breaks decrease”.

Biogas production

Biogas production happens on the biogas plants biggest and most visible part: biogas reactor. Biogas reactor is an oxygen-free space and there is a controlled temperature. Biogas production is a continuous process and is caused by anaerobic bacteria that digest the feedstock.

As a result of digestion biogas is produced which is mainly methane and carbon dioxide + a small amount of other gases such as sulfur compounds. The reactors biofilter effectively removes foul-smelling sulfur compounds from the gas that hinder further processing. The biogas plant or the digestate smell less and fertilise which comes from the biogas process smell less than normal sludge.

Demeca biogas reactor has a device space/ room where biogas is cleaned and dried. After processing and pressurization the biogas is ready to put into the generator for electricity and heat production.

The electricity and heat that comes into the use of the farm is produced by a generator gPower container unit and in cold weather additional heat can be generated by a gas burner in the heating boiler. From the engine and ecuipments comes a muffled voice and the smell does not disturb. As a result of burning only carbon dioxide and water vapor are generated.

Carbon dioxide comes from plants which grows in fields, from renewable feedstock and is considered to absorbed back to new growing plants. That is why biogas is a completely carbon-neutral source of energy and completely emission-free. Biogas is an environmentally friendly source of energy at all stages.

Biomethane

Biogas can still be processed example to biofuel vehicles in a separate gFuel unit which can install and build to the biogas plant at a later stage. The combustible component of the gas is methane and the methane concentration is raised required level by removing carbon dioxide and water from the gas. The generated gas is pressurized and stored in a gas tanks, where it can be refuel or sold on. Production and sale of biofuel opens up new business opportunities for farms.

 “Producing biogas as part of the nutrient cycle reduces environmental pollution. 

Biogas is 100 % renewable and carbon neutral”.
