VGTU Achievements of 2016

December 30, 2016
As the year approaches to an end, it is common to look back at the past year and sum up what has been achieved. The outgoing year 2016 was truly generous with outstanding achievements by members of Vilnius Gediminas Technical University (VGTU) community. It would take many pages to list all of them, but today we would like to remember the most memorable 7 achievements; those, which attracted the most public attention and gained the most publicity in the press in 2016:
 
1. Extremely durable asphalt mixture
 
 
VGTU scientists created an asphalt mixture which withstands a long-term static load. The asphalt mixture is unique in Lithuania. It ensures durability of heavy traffic roads, streets and other traffic areas. This product can also be used for aerodromes' apron areas and ramps, port quays and terminals.
 
 
2. Insulating materials from sheep wool waste
 
 
VGTU scientists developed a method to benefit from sheep wool waste – production of ecological insulating materials. The properties of such materials are very similar to contemporary-classics in insulation materials, but materials produced from recycled wool waste are environmentally friendly during whole period of use and at the end of their life cycle are easily disposed of by using mechanical recycling.
 
 
3. A significant contribution in the field of electrochemistry
 
 
A joint VGTU and VU team of scientists was working on more efficient ways to produce energy from biomass and created an efficient biocathode. The invention of Lithuanian scientists was acknowledged by the global scientific elite – their paper was published in a prestigious multidisciplinary international journal “Energy & Environmental Science”.
 
 
4. The first VGTU's European patent – bio-filter
 
 
Using biotechnologies, a unique bio-filter was created by VGTU scientists. This new product helps to regulate the level of pollution and contributes to solving an especially relevant problem – mitigation of climate change. This achievement granted a first European patent in VGTU's history.
 
 
5. Heated and self-drying bath mat
 
 
VGTU students came up with an idea for heated and self-drying bath mat. Their new product "Warm Feet Mat" works almost like heated floors. There are weight sensors in the mat, activating continuous 15-minute heating cycle when someone stands on it. The mat is charged with a simple mini-USB charger, just like the one we use for our smart phones.
 
 
6. Vehicle control system based on the Internet speed
 
 
Engineers of VGTU “LinkMenų fabrikas“ together with telecommunication company “Tele2” developed a unique vehicle control system based on the Internet speed. The system allows a vehicle to drive at the speed of the 4G Internet in that area: megabits per second are converted into kilometres per hour.
 
 
7. The first digital campus in Lithuania
 
 
VGTU scientists made a first step towards a digital city. They have created a digital prototype of VGTU Saulėtekis campus, which is the first of its kind in Lithuania. A modern digital city is a smart model of a city based on the latest technologies, which encompasses enormous amount of data and information on buildings, their environment, roads, green zones, trees etc.
 
 
We are very proud of the achievements of VGTU scientists, students and other members of the community, and hope that the next year will be at least as generous with achievements, discoveries and pleasant moments as 2016!

New doctoral dissertation
New doctoral dissertation
VILNIUS TECH Library invites you to follow the published new dissertations. The dissertation „Resistance of technological waste-modified concrete to freeze–thaw cycles and alkaline corrosion“  („Technologinėmis atliekomis modifikuoto betono atsparumas užšaldymo ir atšildymo ciklams bei šarminei korozijai“) prepared at VILNIUS TECH by Edvinas Pocius. The dissertation was prepared in 2021–2026. Scientific consultant – Prof. Dr Džigita Nagrockienė. The dissertation was defended at the public meeting of the Dissertation Defence Council of the Scientific Field of Materials Engineering in the Aula Doctoralis Meeting Hall of Vilnius Gediminas Technical University at 10 a.m. on 8 June 2026. The dissertation investigates concrete modified with glass processing waste, concrete sludge, and a crystallizing additive. The goal is to develop concrete that is resistant to freeze–thaw cycles and alkali–silica reaction (ASR) by replacing part of the cement with glass waste and sand with concrete sludge. By selecting the optimal amount of technological waste, the aim is to improve the basic properties of concrete while maintaining its resistance to freeze–thaw cycles and alkali–silica reaction. The tasks addressed in the work include the analysis of glass processing waste and concrete sludge, evaluating their impact on the properties of the cement paste. After determining the recommended waste content, the physical and mechanical properties of the modified concrete are investigated, focusing on resistance to freeze–thaw cycles and alkali–silica reaction. This research sequence aims to substantiate the basic properties and resistance to freeze–thaw cycles and alkali–silica reaction of the newly developed material. The dissertation consists of an introduction, three chapters, general conclusions, a list of references, a list of the author‘s scientific publications, and a summary in English. The Introduction discusses the research problem and relevance, describes the object of research, formulates the aim and tasks, and outlines the research methodology, scientific novelty, practical significance, and statements for defence. The First Chapter discusses active mineral substances, their formation and use in concrete production. It discusses the generation of concrete sludge and glass waste, as well as the impact of their use on the physical and mechanical properties and durability of concrete. The durability of waste-modified concrete and the assessment of carbon dioxide emissions are also described. Conclusions are formulated, and the objectives of the dissertation are refined at the end of the chapter. The Second Chapter presents the materials used, their properties, and their formation. It describes the research methods and equipment chosen to investigate the structure and properties of the concrete and to calculate its CO2 emissions. The Third Chapter substantiates recommended dosages of glass waste and concrete sludge and their effects on cementitious systems. Glass waste was found suitable for cement replacement, and dry sludge for fine aggregate. An environmental impact assessment was also performed. Five scientific articles were published on the dissertation topic in the Web of Science database, Science Citation Index Expanded, peer-reviewed publications with a citation index. Doctoral dissertation readers can search via VILNIUS TECH Virtual Library.
