PROCESS FOR PRODUCING THERMALLY STABILIZED LIGNIN
The present invention is directed to a process for the production of thermally stabilized agglomerated lignin, which avoids melting and/or significant foaming during subsequent thermal processing. The process comprises the steps of providing agglomerated lignin and heating the agglomerated lignin to obtain thermally stabilized agglomerated lignin. The thermally stabilized lignin can be further processed to a carbon enriched material.
METHOD FOR PRODUCING SYNTHETIC RESIN MOLDED ARTICLE IN WHICH MARINE FLOATING PLASTIC WASTE IS USED
The present invention provides a method for manufacturing a synthetic resin molded product which does not require classification of recovered ocean floating plastic trash according to kind of plastic, and can reuse most thereof as a raw material. The method is characterized by including mixing ocean floating plastic trash P (30 to 80 wt %) having a diameter or a side of 5 mm or less or a weight of 0.1 g or less, and a woodchip W (second material) (20 to 70 wt %) having a diameter or a side of 5 mm or less, and not molten under a temperature condition of 200° C. by a mixer 3, supplying a mixture of the ocean floating plastic trash P and the woodchip W to a grinding device 4, grinding the mixture into a powder with a diameter or a side of 1 mm or less, supplying the resulting powder as a raw material for a synthetic resin molded product to a molding machine, and carrying out a molding step.

SUPERCRITICAL FLUID INJECTION FOAMING POLYLACTIDE FOAM MATERIAL AND PREPARATION METHOD THEREFOR
The present application relates to a supercritical fluid injection foaming polylactide foam material and a preparation method therefor. The method includes: first obtaining a surface-modified cellulose nanofiber aqueous solution; then melting and blending the cellulose nanofiber aqueous solution and a polylactide twice; passing same through extrusion, cooling under water, and granulation so as to obtain a polylactide/cellulose nanofiber composite material; then plasticizing and melting the polylactide/cellulose nanofiber composite material in a microporous foaming injection molding machine; uniformly mixing same with a supercritical fluid foaming agent in the injection molding machine; injecting same into a mold cavity; and subjecting the resultant to post-treatment so as to obtain a polylactide foam material. The polylactide foam material has a sandwich structure, in which two outer surface layers are solid layers that do not contain any foam, and the sandwiched layer is a foam layer having a cellular structure.
