Abstract: The bike (10) comprises a frame provided with a front wheel (12) oriented by a handlebar, a saddle (39) and a crankset. The bike (10) further comprises two pivoting rear uprights (18, 19) each carrying a rear wheel (22, 23), the pivoting rear uprights being mounted by independent pivot links on the frame. The crankset actuates two drive means (26, 27, 59, 60) independent of the rear wheels. The drive means of each rear wheel comprises a free wheel (59, 60). The drive means are configured such that, in a bend, only the rear wheel located on the inside of the bend is driven by the crankset, the rear wheel located on the outside of the bend freewheeling and not being driven by the crankset.

Abstract: A system for asbestos neutralization, that includes a neutralization unit having a module configured for sorting of asbestos waste, an asbestos waste grinder; a concentrated sulfuric acid tank, a vat containing a hot diluted acid solution, for which temperature is between 70° C. and 100° C., in which grinded asbestos waste containing asbestos is dipped, the solution is configured for neutralizing asbestos contained in the grinded asbestos waste, a filtration unit to separate, at the end of the neutralization reaction, a solid inert waste from a liquid phase of the diluted acid solution, a regeneration unit for the diluted acid solution, which adjusts the hydrogen potential of the extracted liquid phase by adding concentrated sulfuric acid from the tank, and means for transferring the regenerated solution into the vat.

Abstract: An asbestos waste neutralization device, that includes an acid tank and a vat containing a diluted acid solution, in which waste containing asbestos is dipped, the diluted acid solution neutralizing the waste containing asbestos during a neutralization reaction. The device further includes a filtration unit to separate, at the end of the neutralization reaction, solid inert waste from a liquid phase of the acid solution, and a regeneration unit for the liquid phase of the acid solution, which adjusts the hydrogen potential of the liquid phase of the acid solution by adding concentrated acid contained in the acid tank. In addition, the device includes an attenuation sensor for regenerated liquid phase of the acid solution from the regeneration unit, and a selective precipitation unit for the regenerated liquid phase of the acid solution, depending on the degree of attenuation the attenuation sensor senses.

Abstract: The invention relates to a system for asbestos neutralization, that comprises a neutralization unit comprising, in an atmospheric containment: a module for sorting of asbestos waste, an asbestos waste grinder, which reduces the size of the asbestos waste to a dimension ranging from one-tenth of a millimeter to one millimeter, a concentrated sulfuric acid tank, a vat containing a hot diluted acid solution, for which temperature is between 70° C. and 100° C., in which grinded asbestos waste containing asbestos is dipped, said solution neutralizing asbestos contained in the grinded asbestos waste, a filtration unit to separate, at the end of the neutralization reaction, a solid inert waste from a liquid phase of the diluted acid solution, a regeneration unit for the diluted acid solution, which adjusts the hydrogen potential of the extracted liquid phase by adding concentrated sulfuric acid from the tank, and means for transferring the regenerated solution into the vat.

Abstract: The invention relates to a system for neutralizing asbestos, said system comprising a mobile neutralization unit (200) comprising: an asbestos waste sorting module (225), an asbestos grinder (255) and a hot acid bath (250) for rendering asbestos inert. Preferably, the asbestos waste sorting module comprises: a window with glove boxes; and a conveyor for transporting the asbestos waste in front of the window. In embodiments, the system comprises a means for containing the atmosphere within the mobile neutralization unit and/or the hot acid bath (250) of the mobile neutralization unit (200) comprises sulfuric acid.

Abstract: The asbestos waste neutralization device (10) comprises: an acid tank (23), a vat (16) containing a diluted acid solution, in which waste containing asbestos is dipped, with this solution neutralizing the asbestos waste, a filtration unit (21) to separate, at the end of the neutralization reaction, the solid inert waste from the liquid phase of the acid solution, a regeneration unit (22) for the attacking acid solution, which adjusts the hydrogen potential of the extracted liquid phase by adding concentrated acid contained in the acid reservoir, and means for transferring the regenerated solution into the vat.
