A process for producing a biomaterial product based on sunflower seed hulls/sunflower seed husks comprising providing or producing a sunflower plastic compound (SPC) compounded material (SPC PBS, SPC PBSA), wherein the material is obtained by compounding a sunflower seed hull material/sunflower seed husk material with a biodegradable plastic, for example polybutylene succinate (PBS), polybutylene succinate-adipate (PBSA), or the like. The SPC compounded material is preferably used for producing an injection molded product, for example biodegradable containers, packagings, films or the like, in particular coffee capsules, tea capsules, urns, cups, plant pots, flowerpots, or the like.

Adhesive tapes and/or methods having a substrate in the form of a flat element comprising a composition containing modified polylactic acid and containing the following components: (1) at least one (co-)polymer based on at least one lactic acid; (2) at least one compound comprising at least one carbodiimide group; (3) optionally at least one compound having at least one epoxide group additionally containing at least one ester group and/or at least one aromatic group; (4) at least one phosphorus-containing compound and (5) optionally additives and/or fillers.

The present invention relates to the development of a filler additive derived from processing and/or pressing wastes of the citrus, for polymeric compositions for use in hot processing techniques such as, for example, extrusion, injection molding and 3D printing.

The present invention is directed to a process for manufacturing a biodegradable synthetic polymeric material wherein the process has the steps of binding, pelletizing, extruding; and sealing. Moreover, the invention discloses degrading substances which participate in the first three steps (a, b, c) wherein the degrading substances comprise betaine (C.sub.5H.sub.11NO.sub.2), cassava (yucca) starch (C.sub.6H.sub.10O.sub.5), carrot carotene (C.sub.40H.sub.56), water, carbon monoxide, corn glucose (C.sub.6H.sub.12O.sub.6), and a carboxylic acid of 1 to 6 carbon atoms.

According to the present disclosure, a hydrophobic polymeric composite comprising a hydrophobic polymer matrix with hydrophobically modified particles dispersed therein is provided. The hydrophobically modified particles may be derived from hydrophilic particles modified with organic moieties. The hydrophobically modified particles may also take in the form of core-shell fibers with hydrophilic particles encapsulated inside the core of said fibers or in the form of monolithic fibers embedded with hydrophilic particles. The method for making hydrophobic polymeric composite comprising each of the various hydrophobically modified particles is also provided. The hydrophobic polymer matrix can be chosen from poly(alpha-hydroxyesters), of carbonates, polyurethanes or polyalkanoates. For example, hydrophilic particles, such as barium sulphate, zirconium oxide, tantalum oxide or bismuth oxide, are dispersed in the hydrophobic biodegradable polymers, such as poly-(L-lactide) (PLLA).

A biopolymer blend is provided that comprises a combination of three components: poly (butylene adipate-co-terephthalate) (PBAT); agriculture sourced polylactic acid (PLA); and engineered proteinaceous eggshell nanoparticles. The two polymer components can be present in any ratio but an approximate 70:30 ratio is preferred. The engineered proteinaceous eggshell nanoparticles are preferably about 10-25 nanometers. Also provided are methods of preparing biopolymer film and packaging components. Pelleted poly (butylene adipate-co-terephthalate) and agriculture sourced polylactic acid (PLA) are dissolved in chloroform and mixed together to form a polymer blend, and engineered proteinaceous eggshell nanoparticles are incorporated into the polymer blend, which is then extruded to create a biopolymer film or component.

The present invention relates to a family of preferably bio-based plasticisers and resins containing said plasticisers. The disclosed plasticisers belong to the poly (ester ether) family. Resins containing the plasticisers exhibit a broad range of applicability in terms of suitable processing techniques and utilisation for final products.

Provided is a polylactide resin composition that is used in combination with a specific nucleating agent, wherein the composition is excellent in crystallization half-life and crystallinity degree, and thus can maintain the properties inherent in the polylactide resin while having excellent processability.

The present invention relates to polymer compositions comprising at least one basic additive, and processes comprising at least one process step to obtain the polymer composition or articles comprising the polymer composition. The polymer composition generally displays an enhanced biodegradability.

Compositions and methods are provided that are beneficial for use in downhole applications, especially oil and gas well bores. A composition includes an elastomer doped with a dopant. The presence of the dopant increases a rate of microbial degradation of the elastomer by a microbe. A method includes forming an article including a doped polymer. The doped polymer includes an elastomer doped with a dopant. The method also includes placing the article in a service environment. The presence of the dopant in the doped polymer increases a rate of microbial degradation of the elastomer by a microbe in the service environment.
