CO2Fixator is the commercial name of a mix of bacterial strains and a fungal one.  CO2Fixator exploits microbial competition towards bacterial strains, already present in the soil substrate, to avoid the emission of greenhouse gases due to the fermentation of plant residues in the soil. The CO2Fixator transforms agricultural soil into a Carbon Sink  simultaneously improving its quality. Compared to other CO2 capture techniques and systems, such as reforestation, algae cultivation, air filtration or conversion of CO2 into fuel, CO2Fixator can be applied wherever there is soil, whether agricultural or not, including organic waste, sewage sludge and organic fertilizer.
