We develop, design, execute and operate energy recovery projects for self-consumption of industrial organic waste, as well as improvement and optimization of existing biogas installations.
Bio-refinery is understood as the organic waste management and recovery for manufacturing micronutrients and organic fertilizers.
Intensive and organic farming requires an increasingly larger quantity of organic matter, but it must also be of a higher quality and be able to be used in the irrigation systems.
This brand new bio-refinery model provides a solution to the significant challenge of organic waste management of the area. Also, it covers the huge organic matter and nutrients needs for intensive crop farming, where the soils are not capable, on their own, of having the required structure and nutrients, as they have to bear up to 3 harvests.
One of the innovations of this system lies in making use of the by-products obtained in the recovery process itself, using the energy provided by biogas to concentrate and increase the value of the biofortifiers obtained. By having free energy, we can ensure minimum production costs, sustained over time. Thus, we offer the market a great value, natural and ecologically sustainable product at a competitive price, generated right at the heart of demand.
Biogas is a blend of different gases generated by the degradation of organic matter in the absence of oxygen.
It can be generated from materials such as: plant waste, manures, urban waste, agro-food industry waste, aerobic sludges, etc. In conclusion, from any organic waste or by-product.
This biogas can be used in an engine to generate electricity or heat, or burned in a boiler to generate heat. This versatility makes anaerobic digestion the best choice to recover organic waste.
Furthermore, after fermentation, a semiliquid flow (digested) is generated, and that can be used as a fertilizer.
A Biogas plant is useful to manage organic waste in an integrated way, solving two problems at a time:
A Small Biogas plant is a biogas plant for self-consumption, customized and escalated to the customer’s inherent needs and specifications.
The main advantages of this type of plant are:
This Upgrading process involves removing the biogas CO2, turning it into Biomethane.
Biogas is mainly made up of CO2 (between 30 % and 50 %) and methane (between 50 % and 100 %), the methane being the part that provides the energy power. In the Upgrading process, CO2 is removed through an extraction process by means of amines, increasing the methane volume and, therefore, its purity, matching it in quality with natural gas.
The system is based on an absorber (washing column with amines) and a separation column with attached heat exchangers in which the extraction liquid is continuously purified. Thus, it can be reused in the absorber.
The main advantages of using this technology are:
Another crucial advantage is that only biomethane is pressurized, as compression follows the purification section. As a consequence, the compressor size is up to 50 % smaller in comparison with other technologies, significantly cutting the plant price and power consumption.
It can also produce energy or fuel derived fuel that can be used in the cogeneration plants.
Thanks to an innovative system for the recovery of organic matter, we perform an advanced treatment of waste, in the minimum space, starting at 50,000 t / year, achieving the maximum material recovery (over 93%) and reducing the amount that finally goes to the landfill.
The key objective is to obtain the moist organic fraction for its recovery.
Waste is put under pressure in special chambers with small relief holes, that result in the extraction of the organic part, collected aside from the dry fraction. The resulting moist material, after a cleaning stage, is ready to be digested and to generate biogas.
During the cleaning stage, all the impurities and inert elements from the organic fraction are removed in order to optimize the anaerobic digestion process.
Two products are generated from biodegradable waste:
During the organic separation process, plastic, cardboard, paper, ferrous metals, non-ferrous metals, fine sands, glass and PVC can also be obtained.
