Abstract: The present invention relates to a stable mat (10) based on thermoplastic materials, comprising a core of compacted plastics (14), the cohesion of which is provided by spot thermal fusion (18) in the core of the mass, and a skin obtained by surface thermal fusion and/or a thermoplastic shell (12) firmly attached to the core by localized thermal fusion. Such a mat may serve as bases for civil engineering constructions, for the distribution of loads in the case of loose, unstable, or marshy soils, the stabilization of embankments or of unstable soils, earthquake-resistant protection of foundations of structures and composition of absorbent ballasts of railroads. They may also be used for the manufacture of prefabricated road elements.

Abstract: The present invention relates to a method and facility for preparing lignocellulosic biomass, in particular by means of water extraction and optionally particle-size refinement, for subsequent use particularly in a process of torrefaction, carbonization, pellet production, such as fuel pellets or soil enhancement pellets, or the manufacturing of building materials, or even the preparation of agri-food products, comprising centrifugation (100) of the biomass followed by attrition milling and drying (200).

Abstract: The invention concerns a method for transforming a biomass into at least one biochar, comprising the following steps of: (a) Providing a ground and dried biomass, said biomass containing at least 30% of a lignocellulosic biomass, by mass relative to the dry weight of the ground and dried biomass; (b) Heating progressively this biomass to a temperature higher than 140° C. and lower than 350° C., in an oxygen-free gas stream, under a pressure comprised between 1 and 40 bar; (c) Allowing the reaction to proceed by maintaining the temperature in the 300-700° C. range and the pressure in the 1-40 bar range; (d) Cooling the biomass derived from step (c), at a temperature of at most 100° C., in an oxygen-free gas stream; and (e) Collecting the biochar. The invention also concerns the thus obtained biochar.
