摘要:
Patente de uma composição para fabricação de recipientes biodegradáveis reutilizáveis e comestíveis para armazenamento de líquidos e alimentos, que após o uso a pessoa poderá comê-lo e também os animais, sendo rico em proteína e colágeno. Também poderá ser utilizada na agricultura como adubo orgânico. Atualmente, o impacto ambiental de recipientes plásticos causado à flora, à fauna e aos humanos é preocupante. Milhões de toneladas de plástico são jogadas no planeta. Milhares de animais marinhos morrem sufocados por confundir estes resíduos com alimentos. A poluição do solo por recipiente plástico, o degrada interferindo diretamente nas relações ecológicas. A referida composição, objeto da presente patente é caracterizada por ser constituída de: 52% a 56% proteína de colágeno hidrolisado, 22% a 26% extrato de Symbiodinium thermophilum, 7% a 12% Lipídio de Metaphyta, 3% a 6% de corante.
摘要:
This invention discloses a bioplastic composition comprising biomass as a component comprising a plastic compound resin comprising polybutylene succinate (PBS), polylactic acid (PLA), and additives selected from biomass from the coffee roasting processes, i.e. silver skin of coffee (SSC); and/or at least one fluoropolymer or fluoropolymer derivative as a friction reducing agent. This invention also relates to a process of pretreating the silver skin coffee for using as an additive for bioplastic resin to produce various products or using as a natural color masterbatch together with other plastics via extrusion, injection molding, compression and thermoforming processes in the industrial level.
摘要:
Die Erfindung betrifft eine Zusammensetzung zur Herstellung von Holzimitaten durch Kalandrieren, Spritzgießen oder 3-D-Drucken, die ein Gemisch aus 45 - 80 Gew.-% PVC- Harz und 10 - 50 Gew.-% Reis- oder Erdnussschalenpulver oder eines Gemisches aus Reis- und Erdnussschalenpulver mit einer Teilchengröße von 10 - 250 μm enthält. Die erfindungsgemäßen Holzimitate haben eine sehr holzähnliche Optik und Haptik und sind mit konventionellen Holzwerkzeugen bearbeitbar. Sie sind problemlos lackierbar und verklebbar und eignet sich wegen ihrer sehr hohen Witterungsbeständigkeit besonders für Outdoor-Anwendungen, insbesondere in feuchten oder nassen Umgebungen.
摘要:
Use of a chemically derivatized polysaccharide-protein blend comprising partially water-swellable polysaccharides and proteins, wherein the polysaccharides and proteins have each been at least partially chemically covalently modified by a) at least one noncrosslinking derivatization; and b) at least one crosslinking derivatization, wherein the polysaccharides and proteins have been at least partially chemically covalently crosslinked with one another, and wherein the chemically derivatized polysaccharide-protein blend in aqueous medium forms a hydrogel, as an additive for drilling muds - in the development, completion and exploitation of underground mineral oil and natural gas deposits, and in deep wells.

摘要:
The present invention concerns a plastic composition which is biodegradable, and which does not discharge contaminants during incineration or leave plastic fragments after decomposition. According to the invention the composition comprises: (i) 30-50 % by weight of a polyester which is biodegradable and/or decayable; (ii) 20-40 % by weight of starch from vegetable oil origin from corn, potatoes, and/or sunflower; (iii) 20-40 % by weight of a filler composition comprising dolomite and/or calcium carbonate, wherein the filler composition particles have a polished surface; and (iv) 1-5 % by weight of a binding agent comprising a resin ester of vegetable origin; wherein said polyester and said starch together form a bioplastic base composition and together comprise 55-79 % by weight of the total weight of said plastic composition. The present invention further concerns a method for preparing said plastic composition; a plastic film prepared of said plastic composition; and a waste bag prepared of said plastic film.
摘要:
