TECHNOLOGY

BIOSTABILIZATION 

It is a solid waste treatment process that consists of the biological degradation of its organic fraction through the aerobic activation of the microorganisms present in the environment and the evaporation of most of the water with the heat generated by the biological process. This treatment is adapted for the remaining fraction of undifferentiated waste.

RECOVERY 

It is the reformed hydrogasification process, in which partial oxidation is achieved through the water contained in the waste, as is the partial reforming of the "off-gas" generated within the gasifier itself. The final result is a synthesis gas (Syngas) with a high H2 content, which can be used as an energy vector, due to the versatility of its composition and the possibility of conversion to liquid through Fisher-Tropsch type processes. 

POSSIBLE INPUTS

MAIN SOLID WASTE TREATMENT METHODS

INCINERATION

They are combustion processes of fresh or previously treated MSW, with or without net energy generation.

WASTE SORTING + COMPOSTING

In them, the waste is subjected to mechanical and/or manual processes for separating recyclable materials (metals, hard plastics, etc.), from inert materials (pieces of glass, ceramics, etc.) that are deposited in a controlled landfill; and finally the organic fraction, which is subsequently subjected to aerobic fermentation, that is, in the presence of air, for the production of a compost of variable quality depending on the composition of the organic matter of origin.

WASTE SORTING + DRY METHANIZATION

In this case, the same first separation process already described in the previous treatment is carried out and the organic fraction is subjected to anaerobic fermentation (in the absence of air), to obtain biogas as fuel, depositing the rest of the material resulting from this landfill process or subjecting it to a new aerobic fermentation for the production of compost.

WASTE SORTING + PYROLYSIS

A first process identical to the one described in the two previous treatments is carried out, followed by drying and crushing of the remaining fraction to facilitate its combustion in the absence of oxygen and at low temperature to obtain a syngas as fuel and a synthetic diesel that, in both cases they will require a cleaning and purification process for their later use. The remains of the pyrolysis process must also go to landfill.

BIOSTABILIZATION (BMT) + VALORIZATION

In this treatment from the undifferentiated solid waste (the black bag), with or without selective collection, almost all the degradable organic matter and water present in the waste are eliminated, through an aerobic fermentation process accelerated by aeration continuously forced drying, eliminates the pathogens present in the waste, eliminates bad odors, reduces the volume and weight of the original waste, facilitating its manual and/or mechanical handling to later separate, with greater safety and hygiene guarantees, the recyclable materials and obtain at the end of the process a sanitized and biologically stable material. Finally, by means of a simple mechanical treatment of this material, a solid fuel that can be recovered energetically can be produced, leaving only less than 5% of the original residue to be deposited in the glue dump.
