  • Patent number: 9486774
    Abstract: The present document describes a system and a process for the thermochemical treatment a matter containing organic compounds such as biomass, for the production of useful energetic products such as biochar, bio-oil and gases from non-condensed vapors. The system comprises a reactor comprising a feedstock reservoir having entry and exit, a thermochemical reaction chamber having an entrance disposed under and coupled to the reservoir exit, an exit, and a first heating means for thermal treatment of the matter to produce a solid and a vapor. The system also comprises a feeder having at least one substantially vertical auger operatively coupled to the feedstock reservoir and the thermochemical reaction chamber exit to drive the matter downwardly from the feedstock reservoir exit through the thermochemical reaction chamber.

  • Patent number: 8124401
    Abstract: The invention relates to a method and a system for producing biofertilizers, from sludge that are stabilized, dried, and rich in fertilizing matters originating from high load effluent treatment method. Such solution may be integrated into an already existing treatment facility for industrial, municipal, or agronomical organic effluents (100), and is based on recovering the thermal energy created during the treatment steps of such system in bioreactors (120), air suppression units (122), biodrying units (500), drying units (600), and other units. Such recovery of energy creates a synergy that allows the increase of efficacy and yield of bioreactors (120) due to a greater stability from the temperature regulation, thus ensuring an important energy saving for the final drying step in producing biofertilizers.
