This innovative technology allows waste to be composted with a liquid consistency, obtaining a reduction in the volume of said fraction of up to 70% and significant savings in the cost of digestate management.
The biodigester consists of:
- Reinforced concrete enclosure, covered.
- CLF MODIL self-propelled machine that moves along the premises using rails.
- Automatic control system that regulates the basic parameters of the process.
Through an automated feeding and progressive mixing system, the liquid fraction (digestate or slurry) is incorporated into a lignocellulosic waste base, developing an oxidative decomposition process lasting approximately between 40 and 180 days. The system controls both the physical-chemical composition of the biomass as well as the oxygen content, humidity and the carbon-nitrogen ratio.
The result of this process is a high quality organic amendment with a solid consistency, free of pathogens, odor emissions, stabilized and homogeneous.
The CFL Modil system is specially designed to provide environmental solutions to the management of both slurry and digestate (by-products generated in biogas plants) since they are waste that, due to their characteristics, entail complications for their management.
Controlled composting technology provides a solution that improves both the economic and environmental viability of biogas plants since, in addition to facilitating the management of the digestate due to the significant reduction in the volume of water in the mixture, it also significantly reduces the risks of contamination. of aquifers and the emissions of polluting gases derived from their management.
CFLModil technology provides something that none of the existing treatments achieve: a comprehensive solution to the management of digestate from agroindustrial biogas plants, increasing the viability of newly built biogas plants and improving the added value of the digestate generated in existing ones. existing.
SPD Navarra de Biogás has presented this new technology to the innovation contest of the first Renewable Gas Show.
