Purpose of the development: Designed to optimize the development of industrial technology production of biodegradable plastics.

Recommended application field: Medical - Surgical elements bioimplantanty, matrices functioning cells for cell and tissue therapy (reconstruction of soft and hard tissues and organs damaged in orthopedics, dentistry, urology), biocompatible intravascular prostheses (stents) in cardiac surgery. Hygiene and sanitation - nonwoven materials, disposable products. Pharmacology - lasting drugs of controlled release formulations. Agriculture - polymer coatings, packaging of fertilizers and pesticides for targeted delivery, reducing the dispersion and accumulation of xenobiotics in the biosphere. Food, light industry, public utilities.

Advantages over analogues: Benefits: - An integrated approach to solving scientific and technical problems, the goal - the creation of a new industry which bioplastics production with high consumer properties and high export potential; - Formed a team of researchers and specialists in various fields (biophysics, microbiology, biotechnology, materials scientists, engineers and physicians); - The presence of his own collection of high-producing strains capable of synthesizing PHA different structure implemented by the laboratory to the proficient level on various substrates; - The possibility of the synthesis of polymers of different composition with modified properties without substantially changing the process parameters and the use of expensive media; - The possibility of the synthesis of polymers of different values for a range of applications due to the raw materials of different origin - from monouglerodnyh substrates to waste products (CO2, sugar and sugar-containing substrates, organic acids, hydrogen, of various origins, including the products of processing low-grade brown coal); - Availability of the technologies developed in the polymer processing special products; - Standard results of biomedical research confirming bilogicheskuyu safety and compliance with the requirements of bioplastics derived medicine.

Description of the development:
()
Developed and implemented an efficient biotechnological process for the preparation of biodegradable thermoplastic polyesters linear polyhydroxyalkanoates (PHAs) with - using copyright microbial strains of the genus Ralstonia, characterized by the possibility of the synthesis of polymers of different chemical structure and composition using a variety of substrates. Microbiological process for producing polymers comprising culturing the producing strain in a liquid medium at a constant aeration with sterile air and stirred with an excess of a specific mode of the carbon substrate and imbalanced growth when the main process (nitrogen) cellular macromolecules limited to any component of the substrate. PHAs in a number of physical and himichekih properties similar to not degrade in the environment synthetic polymers (polypropylene, polyethylene). In addition to thermal plasticity PHAs have antioxidative properties, biodegradability and biocompatibility. As a result of the process there is a special opportunity, without significant changes to existing technology and equipment to organize the production of polymers with different cost using new types of raw materials, including industrial waste in the regions having different energy and raw material potential. In general, the technology allows for biodegradable plastics is significantly cheaper (3-5 $ / g) than currently used technology as well as to synthesize polymers (homopolymer and copolymer of hydroxybutyrate and hydroxyvalerate hydroxybutyrate with different ratios manometer) on various raw materials. Foreign market offers two types of polymers in this class: polyhydroxybutyrate and copolymers hydroxybutyrate. PGA has 100% degree of purification and cost $ 05.03 per gram, and polyhydroxybutyrate-hydroxybutyrate and copolymers have 5% impurities and cost $ 10-12 per gram. When volume production of bioplastics 100t / year This is an revenue of 300 million. $ / Year.
