The subject of the present invention is to provide a resin material in which woody biomass and a thermoplastic resin are uniformly mixed, and which is easy to mold. The present invention provides a molding resin material containing a pulverized product from a woody biomass-derived torrefied product and a thermoplastic resin.

A composition for eco-friendly crayon and a method for producing the eco-friendly crayon is disclosed. The composition comprises one or more non-toxic ingredients including soy wax, beeswax, and coloring pigment. The waxes are combined and heated in a heating chamber. The mixture is heated to form a halfway melted mixture. The coloring pigment is added to the halfway melted mixture and stirred until fully dissolved. The dissolved mixture is then poured into a mold and cooled. The cooled mixture is removed from the mold to prepare crayons for use. The crayons are made in a variety of shapes and sizes. The non-toxic ingredients are free of harmful components and prevent crayons from remaining in the user's hand. Further, a method used to prepare the non-toxic crayon uses waxes and coloring pigment without any additional ingredients, thereby providing softer crayons with high level of eco-friendly attributes.

The invention relates to a method for producing a biodegradable thermoplastic starch-based article intended to come into contact with foodstuffs. In this method, the semi-crystalline starch granules are transformed into a homogeneous and almost amorphous material, called thermoplastic starch, by the addition of plasticizers at high temperatures and under shear. Thermoplastic starch is modified with organic acid during melt processing to prevent the retrogradation of starch. Moreover, cellulose derivatives are used as the reinforcement filler of thermoplastic starch. The article is produced using hot-pressing and then coating by immersion in a waterproofing solution.

A suture for lifting is disclosed. The suture comprises: a medical fiber yarn; fixing parts formed at one side of the fiber yarn and fixable to the skin; and anchor parts protruding on an outer circumference of the fixing parts, wherein the anchor parts are integrally formed with the fiber yarn by a double injection.

Stapling assemblies for use with a surgical stapler and methods for manufacturing the same are provided. Three dimensional adjuncts for use with a surgical stapling assembly and methods for manufacturing the same are also provided.

Provided are an inorganic substance powder-blended biodegradable resin composition exhibiting excellent processability, sufficient mechanical strength and excellent flexibility as a molded product, and having economic advantage, as well as having excellent degradability under a natural environment and a molded product formed by using the composition. Provided is a molded product molded by using an inorganic substance powder-containing biodegradable resin composition including: a biodegradable resin and an inorganic substance powder in a range by mass of 10:90 to 70:30, in which the biodegradable resin is a multicomponent hydroxyalkanoic acid copolymer comprising lactic acid and other hydroxyalkanoic acid and the inorganic substance powder is heavy calcium carbonate.

A compostable single-use container generally includes a substantially planar lid component and a tray component. The lid component has a top surface and a bottom surface. The tray component has a generally planar top surface adhesively bonded to the bottom surface of the lid component with a sustainable adhesive, and a chamber configured to store an object. The tray component is thermoformed fiber comprising at least one of recycled cardboard, hemp straw, and cannabis straw. The lid portion comprises at least one of a natural-fiber card stock and a compostable sticker.

A blown film of soil biodegradable aliphatic polyesters produced primarily from diacid and diol monomers. The diacid monomers may be of any type including succinic acid, adipic acid, and hexanedioic acid. The diol monomer may be of any type including ethylene glycol, propanediol, butanediol, and hexanediol. Commercial aliphatic polyesters produced from diacid and diol monomers include polybutylene succinate (PBS), polybutylene adipate succinate (PBAS), and polybutylene adipate (PBA). Comonomers may also be added. Such comonomers include chemicals with a single carboxylic acid, hydroxy, or amine moiety, which act as chain terminators, chemicals with three or more carboxylic acid, epoxy, and/or hydroxy moieties which, act as branching agents.

A disposable eggshell eco-friendly material and manufacturing method are disclosed. The disposable eggshell eco-friendly material, for volume ratio, includes 50%-80% of calcined eggshell powder, 10%-48% of biodegradable polymer, 1%-5% of natural degradation agent, and 1%-5% of natural binding agent, which are subjected to a mixing and stirring step according to such ratios, and then subjected to a pelletizing step to be first prepared as a plurality of disposable eggshell eco-friendly material pellets, and the disposable eggshell eco-friendly material pellets being then subjected to a shaping and forming step by means of one of film blowing, extruding, vacuum forming, bottle blowing, injecting, and drawing, to obtain a disposable eggshell eco-friendly material product that is disposed of after one time of use.

Methods of making articles with a 3D printer using biomaterials that retain physical properties and biological activity are discussed. Methods can include providing a crosslinkable material and a biomaterial to a 3D printer, and crosslinking the materials to form an implant. Biomaterials can include, among other things, bone, or tissue.
