METHOD FOR PRODUCING POLYHYDROXYALKANOATE AND USE THEREOF

An objective of the present invention is to provide a production method that enables PHA (e.g. PHA powder) to be produced with high productivity. The above is achieved by providing: a method for producing a polyhydroxyalkanoate, including the steps of (a) preparing an aqueous suspension that contains a polyhydroxyalkanoate and an alkylene oxide-based dispersing agent and has a pH of not more than 7 and (b) spray-drying the aqueous suspension prepared in the step (a); and the like.

BIODEGRADABLE COMPOSITE AND PRODUCT CONTAINING BIODEGRADABLE COMPOSITE

A biodegradable composite includes an organic matter and a porous material, wherein the organic matter has viable bacteria, and a total plate count of the organic matter is greater than or equal to 10.sup.4 CFU/g. The organic matter accounts for 40% to 80% of a weight of the biodegradable composite. The porous material accounts for 20% to 60% of the weight of the biodegradable composite. The biodegradable composite could instantly remove unpleasant odor and accelerate a decomposition process to form compost. A product containing the biodegradable composite is provided as well.

Soil biodegradable blown film bag formulation

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.
