On Mixing and Separation During Polyhydroxyalkanoates Extraction – Yield and Purity Optimization

Popis výsledku v původním jazyce

Polyhydroxyalkanoates (PHAs) are biodegradable thermoplastic polymers naturally produced by various organisms. Cupriavidus necator, which biomass was extracted in this work, is one of the most promising sources. In conjunction with utilizing waste substrates (e.g. used cooking oil) it offers cheap and near-to-zero carbon emission concept. Unfortunately the most economic form of production, which enables PHAs to be competitive with oil-derived plastics, utilizes halogenated hydrocarbons like chloroform. This means full recycling of solvent used in technology to prevent environmental harm. In case of accident, apart from all precautions, the amount of such solvent kept in factory need to be minimized, which means perfect optimization of all processes involved. Optimizing the amount of chloroform needed for effective extraction of unit amount of biomass is also important for product purity. Polymer purity is very important for numerous applications, typical example are biomed applications. Unfortunately
