The present disclosure discloses a novel composition for transforming a non-biodegradable material into a decomposable material. In one embodiment, the non-biodegradable material may be plastic. The composition comprises a carbonate or a bicarbonate compound, a plant extract, a hydrating agent, and a coloring agent. The carbonate or bicarbonate compound, the plant extract and the hydrating agent are mixed in a predetermined ratio by weight along with the coloring agent and maintained in an aqueous medium. In one embodiment, the novel composition is applied on the non-biodegradable material to degrade it into a decomposable form. In another embodiment, the novel composition is mixed with the non-biodegradable material to degrade it into a decomposable form.

The present invention provides recyclable copper clad laminates (CCLs) each including copper coil and a recyclable/degradable fiber composition, and printed circuit boards that are made of or include the CCLs of this invention. Also provided are method for recycling these CCLs and printed circuit boards.

A foamable composition comprising at least one cellulose acetate, a plasticizer, a nucleating agent, and either a chemical blowing agent or a physical blowing agent is disclosed. The composition is formed into foamed articles that are biodegradable.

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.

The present invention provides a master batch composition for environmentally degrading conventional plastics including a carrier resin, at least one oxidative degradant, at least one nature biodegradable degradant and at least one foaming agent. The present invention also provides a plastic product which is environmentally degradable at a very low cost versus conventional bio-sourced plastics, and has broad applications for single-use disposable applications or for short-lived products that are discarded within two years of manufacture.

A biodegradable sampling bag for containing samples or the like, comprises a flexible enclosure defining a chamber adapted to contain therein the sample, the flexible enclosure being made of a plastic material, which contains an additive that renders the flexible enclosure biodegradable when exposed for a sufficient period of time to microbial action. The additive is adapted to enable microorganisms to metabolize the molecular structure of said flexible enclosure. The additive is effective in altering the polymer chain of the plastic material to allow microbial action of a suitable environment to colonize in and around the plastic material, whereby microbes can then form a biofilm on a surface of the flexible enclosure and secrete acids which break down the entire polymer chain. The flexible enclosure, when exposed to microbial action, is adapted to withstand biodegradation for a given period of time, typically of at least three months.

This invention is directed to composites and films comprising hydroxyapatite, biodegradable polymer, a biocompatible surfactant with inorganic fullerene-like (IF) nanoparticles or inorganic nanotubes (INT); methods of preparation and uses thereof.

Provided is a biodegradable resin molded product that exhibits excellent processability and sufficient strength as the molded product, is advantageous in terms of cost and at the same time, has excellent biodegradability under an environment, in particular, marine biodegradability, and a method for producing the same, and pellets used therefor. The molded product is produced using a biodegradable resin composition including a biodegradable resin and heavy calcium carbonate particles in a range by mass of 50:50 to 10:90.

An oxo-biodegradable antimicrobial receptacle for organic waste or waste from care activities which comprises a layer comprising low density polyethylene, an oxo-biodegradation additive at between 0.2 and 2.2% by weight and an antimicrobial additive at between 0.2 and 2.2% by weight, distributed in the polyethylene. It affords a period of preservation, in the dark, of at least 3 years, preferably 5 years, at a temperature not exceeding 30° C. The preservation is estimated by the carbonyl optical density resulting from the degradation of the polyethylene, measured according to the standard ISO 10640-2011 by FT-IR spectroscopy. The oxo-degradation is inhibited by the absence of light, and a period of degradation estimated by the carbonyl optical density of less than 2 years. The oxo-degradation additive does not promote Clostridium difficile spores.
