Abstract:
A biodegradable plastic composition enabling to stably adjust biodegradation rate, improve hydrolysis resistance and heat resistance, and retain transparency, molded articles thereof and a method for controlling biodegradation rate of the biodegradable plastic. In more detail, a biodegradable plastic composition, characterized in that said composition is made by compounding 100 parts by weight of a biodegradable plastic (A), in particular, an aliphatic type polyester with 0.01 to 5 parts by weight of a carbodiimide compound (B) and 0.01 to 3 parts by weight of an antioxidant (C), in particular, a hindered phenol type antioxidant with a molecular weight of not less than 400 alone or mixed antioxidants of said hindered phenol type antioxidant and a phosphite type antioxidant, a molded article thereof and a method for controlling biodegradation rate of the biodegradable plastic.
Abstract:
The present invention teaches a chemiluminescent device along with a process for its production. The invention specifically relates to a chemiluminescent article of manufacture which includes a containment device and chemical system, both of which may be selected so as to be particularly susceptible to environmental degradation subsequent to their use. In a preferred embodiment the chemiluminescent device is categorized as being biodegradable, i.e. designed to be capable of losing its physical form and re-entering the environment.
Abstract:
Described herein are improved surgical fixation devices and methods of making the same. The methods comprise mechanochemical processing and vacuum annealing of biocompatible polymer-nanomaterial mixtures to form composites exhibiting superior mechanical properties.
Abstract:
The present invention relates to a biodegradable resin having outstanding colouring properties, and provides a resin composition which does not give rise to problems such as reduced strength due to colouration. The composition of the present invention, suggests that a PBSAT resin is used as a biodegradable resin, and colouration is performed with same. Also, at this time, the colourant can be mixed in the form of masterbatch. In the present invention, the resin composition is used in the production of various products, in particular monofilament yarn produced via spinning and a fishing net manufactured from same is provided. Fishing nets such as the above are advantageous in that such fishing nets can be realized in various colours in accordance with customer requirements and satisfy the required strength and, after use, degrade naturally in seawater and so do not give rise to problems like environmental pollution.
Abstract:
The present invention relates to a masterbatch composition comprising high concentration of biological entities having a polymer-degrading activity and uses thereof for manufacturing biodegradable plastic articles.
Abstract:

Also provided are method for recycling these CCLs and printed circuit boards.
Abstract:
A stone based copolymer substrate includes calcium carbonate (CaCO3) from approximately fifty to eighty-five percent (50-85%) by weight and varying in size generally from 1.0 to 3.0 microns, high-density polyethylene (HDPE) from approximately two to twenty-five percent (2-25%) by weight and a biopolymer from approximately two to twenty-five percent (2-25%) by weight. The substrate may include a biodegradation additive from approximately three fourths of a percent to two percent (0.75-2%) by weight. By selectively adjusting the ranges of the substrate's components, various products can be made to replace current tree-based and plastic-based products. The substrate can be configured to be tear proof, water proof, fade resistant and fire retardant while utilizing less energy and producing less waste during its manufacture. In an exemplary embodiment of the invention, the stone used in the substrate includes limestone.
Abstract:
[Obj ect] To provide a biodegradable material that has sufficient mechanical strength, considering in vivo use also, and that can suppress pH changes caused by acidic degradation products. [Solving Means] Provided is a biodegradable material using polyester as a base material, including calcium phosphate particles having an average particle diameter of 10 to 1000 nm.
Abstract:
Compositions comprising 1,3-propanediol and an extraction product are provided, and the 1,3-propanediol in the composition is biologically derived. Also provided are processes for extracting an extract from a source. These processes comprise providing 1,3-propanediol and mixing the 1,3-propanediol with the source. This serves to extract the extract from the source into the 1,3-propanediol. The processes also include separating the source from the ester and extract.
