  • Patent number: 11261310
    Abstract: The present invention relates to a method for treating fragments of polyvinyl butyral (PVB) in which glass shards are encrusted in or on the surface of the PVB. The method involves placing PVB fragments in contact with an aqueous solution comprising a cationic surfactant and a weak base, to obtain a mixture. This mixture, subjected to ultrasound within a defined temperature range, leads to separation of the glass shards and the PVB. In particular, the inventors have discovered that the combined, simultaneous, and complementary action of a weak base, a cationic surfactant, and ultrasound, at an appropriate temperature, made it possible to detach and/or unembed the glass shards fixed to the collected PVB without degrading the polymer matrix.

  • Patent number: 11021720
    Abstract: A process for producing ethanol includes steps of pre-treatment of the lignocellulosic vegetable raw material, including the steps consisting in destructuring the lignocellulosic vegetable raw material, then in separating, on the one hand, the cellulose (C6) capable of then being hydrolysed (and fermented for the production of ethanol) and, on the other hand, the hemicelluloses capable of then being hydrolysed and the lignins. The hydrolysis of the cellulose and of the hemicelluloses is then carried out in a sequenced manner according to the following steps consisting in: i) beginning the enzymatic hydrolysis of the cellulose by at least one enzyme for a first period with a view to obtaining an intermediate hydrolysate; ii) adding hemicelluloses to the intermediate hydrolysate; iii) continuing the enzymatic hydrolysis of the mixture until a final hydrolysate is obtained at the end of a total period of enzymatic hydrolysis.
