Abstract: A biodegradable composite comprising a polymeric matrix including but not limited to poly lactide (PLA), poly (butylene succinate) 20 (PBS), poly(butylene succinate adipate) (PBSA), including bio-based PBSA (BioPBSA), poly(butylene adipate-co-terephthalate) (PBAT), polycaprolactone (PCL), polyhydroxyalkanoate (PHA(s)), poly(3-hydroxy)butyrate (PHB), poly(3-hydroxy-butyrate-hydroxyvalerate) (PHBV), copolyester of the monomers 1.4-butanediol, adipic acid and terephthalic acid (Ecoflex™) and polypropylene carbonate (PPC), and biocarbon, a.k.a. biochar or pyrolyzed biomass as a sustainable filler. The biodegradable composite achieves high oxygen barrier with balanced water barrier. Also, a method of manufacturing the biodegradable composite and articles of manufacturing comprising the biodegradable composite. The articles of manufacturing have application in limiting gas permeation into a package and extending shelf life of a material.

Abstract: Composites containing one or more synthetic plastics, such as thermoplastics, one or more natural materials, such as plant/tree fibers, and biochar and/or torrefied material are described herein. The composite can contain additional additives, such as reinforcing agents and/or fibers, compatibilizers, etc. The composites have improved mechanical and/or physical properties, such as strength, impact strength, rigidity/modulus, heat deflection temperature, moldability/melt flow index, renewability, and lower cost compared to composites that do not contain the biochar and/or torrefied material. The presence of the biochar and/or torrefied material also serves to remove the odor often associated with natural fibers and other additives.

Abstract: A biodegradable composite including: (a) a polymeric matrix having a biodegradable polymer; (b) a filler; and (c) an anhydride grafted compatibilizer including one or more biodegradable polymers modified with an anhydride group. The composite may also include (d) polymer additives such as polymer chain extenders or plasticizers. An in situ method of manufacturing the biodegradable composite of the present invention, including the steps of: (a) melting one or more biodegradable polymers in the presence of a functional monomer and a free radical initiator to form a mixture; and (b) adding a filler and polymer additives to the mixture thereby manufacturing the biodegradable composite. A method of manufacturing a biodegradable polymer including (a) synthesizing a compatibilizer by (i) mixing a free radical initiator and a functional monomer, (ii) melting one or more biodegradable polymers to form a melt, and (iii) combining the product of step (i) and the melt of step (ii) thereby synthesizing the compatibilizer; and (b) mixing the compatibilizer of step (a), with a matrix of one or more biodegradable polymers and a filler and polymer additives, thereby manufacturing the biodegradable or compostable composite.

Abstract: Toughened polyolefins and methods used to produce toughened polyolefins in presence of a bio-filler. These materials can substitute traditional thermoplastic polyolefins known as TPOs or mineral filled TPOs. Exemplary compositions include a phase based on α-olefin elastomers and the use of biobased fillers. The bio-based filler used, can be a material rich in elemental carbon content. The use of additives is of regular usage for these compositions as they may be related to coupling agents, UV absorbers, light stabilizers, antioxidants, and so forth. These composition offer a remarkable lower density compared to traditional TPOs compositions altogether with bio-based value-performance addition.

Abstract: Biocarbon is presented as an alternative to synthetic carbon black. Master batches having biocarbon for usage in raw plastics and/or the production of composites. Biocarbon is mainly derived from plant biomass, but other sources can be used. A method of producing the master batch: (a) pyrolyzing processed biomass in an oxygen-starved environment to produced biocarbon; (b) comminuting the biocarbon in a reduced oxygen atmosphere; (c) cooling the comminuted biocarbon; (d) mixing the cooled comminuted biocarbon with a carrier resin, thereby producing the master batch.
