A method for producing a foam, wherein polyol and an isocyanate are combined in a mold, and wherein an additive of biological matter and/or waste materials is added at the same time, before, or after, wherein the additive is pretreated.

The present invention relates to polymer compounds containing hemp and/or components of hemp, and methods for producing such polymer compounds.

The present invention provides methods for preparing the nut waste composites from a nut waste component, one or more binders, and an oil using a compounder/extruder.

The present invention relates to biodegradable and compostable granules consisting of natural ingredients comprising starch and thickening and gelling agents and does not comprise bioplastics. According to the invention, the granules are used for producing biodegradable and preferably compostable products and articles of daily use. The present invention also relates to methods for producing the granules according to the invention, as well as methods for producing different products by using the granules according to the invention.

A moisture barrier layer-foamed polymeric composite sheet underlayment article comprising a foamed polymeric sheet and a moisture barrier layer adhered thereto is disclosed. In one aspect, cork particles are present in the composite.

The present invention relates to polymer compounds containing hemp and methods for producing such polymer compounds. More specifically, the invention relates to such hemp-containing polymer compounds containing one or more property-enhancing additives.

The present disclosure relates to composite materials comprising a resin and at least one sheet that comprise optionally cellulose filaments (CF), fillers and optionally reinforcing fibers as well as methods for the preparation thereof. The methods comprise impregnating the sheets comprising the cellulose filaments, fillers and optionally the reinforcing fibers or a stack thereof with resin. The composite materials can optionally comprise at least one other sheet, the at least one other sheet being different from the at least one sheet and comprising fibers chosen from wood pulp, fiberglass, natural fibers and mixtures thereof. The sheet can also be in the form of a panel of a preform.

Embodiments herein are related to hydrophilic open cell foams with particulate fillers. In an embodiment, an article is provided that has an open cell foam structure including a hydrophilic polymer and about 0.1 wt. % to about 40.0 wt. % of a particulate filler dispersed within the hydrophilic polymer. The open cell foam structure can exhibit a rate of absorption of water greater than an otherwise identical foam lacking the particulate filler. Other embodiments are included herein.

A process for the manufacture of biodegradable plastic films in aqueous environment, starting from vegetal wastes in powder form includes dissolution at a temperature lower than 50° C. of waste material in form of a powder in an aqueous solution of hydrochloric acid, and transfer of the aqueous solution in a casting mould and evaporation of the aqueous solution, to yield the biodegradable plastic film. The total concentration of the hydrochloric acid is equal to or lower than 5% by weight. The aqueous solution may include acetic acid. The aqueous solution may also be filtered or centrifuged and/or subjected to dialysis against pure water.

The invention relates to a method for coating a planar workpiece. In order to provide a planar workpiece, which is produced from a workpiece having lignocellulose fibers and a proportion of more than 50 wt % binding agent and optionally filler, with improved performance characteristics, a method is provided having the following steps: providing the planar workpiece, which has an upper face and a lower face and a lateral surface, applying a coating, applying a decoration, optionally structuring the coating, at least on a portion of an upper face, a lower face, or a lateral surface, in each case, and optionally curing the coating.
