The disposal of plastic products is very difficult and poses a significant global burden on the environment. This problem is resolved through the use of bioplastics based on PHA, which decompose spontaneously after some time and which are able to replace the PET bottles and other plastic products which have been used to date. Unfortunately, the production of bioplastic has been quite difficult and energy-consuming. However, a team led by Doc. Márová of the Faculty of Chemistry has discovered a method of producing PHA bioplastics from oil used in deep-frying.

Prof. Ing. Jiří Adámek, CSc. and Ing. Michal Batelka of the Institute of Building Testing at the BUT Faculty of Civil Engineering are the originators of a new technical solution concerning slag-agloporite concrete. This is prepared using artificial sintered aggregate of power-plant or heating-plant fly-ash, so-called agloporite - namely the 4-8 mm fraction. As an additional filler, power-plant slag of the same fraction is used as a substitute for natural aggregate.

“A heat exchanger is a device intended for exchanging energy between systems and buildings of various parameters. An example of a small heat exchanger is a radiator in a central or floor heating system which delivers heat from warm-water, low-pressure circulation to the environment of a residential apartment containing another medium – air.”⁽¹⁾

Scientists from the Faculty of Chemistry have developed a material produced by a special technology from a modified inorganic cement (e.g. an aluminate cement with the addition of a refractory component), a polymer soluble in water (e.g. a polyvinyl alcohol acetate of polyphosphate), water and a plasticiser (e.g. glycerol) for heat-resistant applications.

A group of scientists from the Faculty of Mechanical Engineering at BUT headed by Ing. Jan Jedelský, PhD. has developed a realistic model of a part of the human respiratory tract intended for studying the deposition of aerosols deposition and how best to manufacture them.

Vehicle spring suspensions have limited service-life yet simultaneously have a crucial effect on driving characteristics of a car. Therefore shock absorbers have to be checked regularly. Scientists at BUT know a way how to test shock absorbers using a sensor on an independent stand which is connected to an ordinary PC without any a special converter.
