A team from IP-BAS is looking for a way to increase the efficiency of glycolysis for the recycling and reuse of waste materials from polyethylene terephthalate (PET), optimizing the concentration of the catalyst and the yield of bis(2-hydroxyethyl) terephthalate (BHET) in the presence of titanium (IV) phosphate (TiP) as a catalyst in conventional and microwave (MW) heating for energy saving. The product obtained from glycolysis can be directly used for further processing without the need for additional separation procedures, for example in the synthesis of phosphorus-containing flame retardants.

Institute of Chemical Engineering – BAS presents a method for optimal synthesis and management of resource-assurance chains for biodiesel, bioethanol, biogas and biohydrogen and productions from the food industry.
The methods for optimal design of strategic DOM for the production of biofuels and tactical for the production of food products make it possible to analyze the stages of the entire life cycle of each of the products under consideration, which includes all activities in the chain from the supply of raw materials, through the production itself to the final users.
The methods simultaneously take into account the three aspects of sustainability – economic, ecological and social.
The resulting optimal solutions in terms of determining: selection of raw materials and suppliers; places for the production of agricultural crops for the production of biofuels; waste biomass processing sites for biofuel production; locating the installations and facilities for the production of biodiesel, bioethanol and biogas, as well as the optimal location of charging stations for biohydrogen; production capacity; the transport network; biofuel blending sites; the markets etc. can serve as a basis for making optimal decisions by managers that take into account all three indicators of sustainability.
The technology is at the stage of readiness for implementation.

Institute of Chemical Engineering – BAS presents a method and installation for the processing of urban household waste by incineration.
Incineration of waste in the presence of an increased content of water vapor reduces emissions of nitrogen oxides.
Тhe method enables the utilization of waste heat from combustion and its subsequent use for heating purposes. The exhaust gases during the combustion process are treated in a packed scrubber column, where their purification is carried out.
The technology has opportunities for implementation in all cities with built-in central heating and large enterprises with hot water needs for technological purposes.
