Biogas is obtained from the fermentation of vegetable substrates from the agricultural or agro-industrial sector and organic substrates such as dung when the right environmental conditions are present in the digester (no air, appropriate temperature, continuous mixing), allowing the bacteria to transform the organic substance contained in the biomass.
Biogas is produced from energy crops such as maize and sweet sorghum, from crop residues, organic vegetable waste and animal by-products, manure and slurry, and is used as a fuel to generate electricity and heat

• The electricity is channelled into the grid, guaranteeing a high investment return and self-sufficiency for the farmer.
• The heat can be used on the farm or used or sold for domestic, business and industrial heating.
• The digestate (the process residue) is an organic fertiliser which is re-used in agriculture, without any additional cost, thus completing a natural environment-friendly cycle without any contaminating waste.

Seko, via its Agripower division, is now marketing a second generation of biogas plants, designed and built for top performance in the multi-faceted world of international agriculture.
The great advantages of our technology, confirmed also by the numerous patents registered, are all targeted at development of the highest energy efficiency with maximum saving in biomass and optimised plant operation.

In mechanical and biological terms, we have made important innovations in the preliminary phase of loading and pre-treatment of the solid biomass, a decisive factor for increasing biogas production.
Thanks to a patented mechanical pre-treatment system, using a special machine called Bio-Refiner, all the biomass fed to the plant is crushed and finely chopped, thus increasing the surface area for bacterial attack with consequent improvement in breakdown.

The material is fed into the pre-fermenter by pumping the biomass and not by means of loading modules or loading augers, thus minimising both servicing costs and replacements of mechanical parts.

The heating and mixing technology applied to our pre-fermenter operating system produces, via bacterial inoculum from the storage tanks or the digesters, enzymatic hydrolysis of the fresh biomass, triggering biogasification in only 2-4 hours compared to the 24-36 hours required by traditional plants.

The entire process is automatically controlled by a user-friendly software, developed by SEKO, which allows management, programming and recording of all the functions and operations, also in remote mode.
The system provides complete management of all the plant operating parameters, unrivalled on the international biogas scene and developed by SEKO to facilitate management of a complex system with ingenious simplicity, designed and built to operate in all working conditions, even when routine and extraordinary maintenance is scheduled.

In addition, the modular standardised configuration adopted in the production of our biogas plants allows substantial simplification of the entire process with consequent financial savings and easy management.
