  • Publication number: 20230192983
    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.

  • Patent number: 11332371
    Abstract: The invention relates to a method of preparing sub-micron biocarbon materials using biomass that is chemically modified with organic or inorganic agents including but not limited to acrylamide, glycine, urea, glycerol, bio-glycerol, corn syrup, succinic acid, and sodium bicarbonate. The use of foaming and heating methodologies which could be either pre or post carbonization and subsequent particle size reduction methodologies for the creation of cost-competitive sub-micron biocarbon particles and fibers for a variety of applications.

  • Patent number: 10472440
    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 ?-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.

  • Patent number: 10414880
    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.

  • Publication number: 20180127554
    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.

  • Patent number: 9809702
    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.
