Smart technologies for cleaning and preserving the marine ecosystem


Hackathon organized jointly with Technical University of Varna

Join the hackathon! Let your imagination run wild and bring forth your technological and innovative ideas!

19-20 November 2022

Start: 9:00 | 19.11.2022
End: 17:30 | 20.11.2022 

Technical University of Varna
Conference hall, NUK



The hackathon is a technological event for developing software projects, characterized by a competitive and team-oriented nature, bringing together programmers (and not only) who work on creating a prototype of a product or a solution to a specific problem.

The event is free for  students from all universities in the country, as well as 11th and 12th grade students.


Throughout the two days of the event, participants will be provided with:

  • Open workspace
  • Stable internet connection
  • Food for each day
  • Cold and hot beverages


According to research by the World Health Organization, over 90% of Bulgarians nationwide directly feel the effects of air pollution. The advancement of technology provides ample opportunities to offer solutions that can help transform cities into more environmentally friendly places. Building an "eco-city" is associated with access to information about the latest trends in reducing carbon emissions, smart solutions in the use of natural resources, climate preservation, expanding green spaces, and more. Increasing expertise in the field, as well as raising awareness and knowledge throughout society on the topic, would be a step towards effective actions to achieve a cleaner and healthier living environment all around us. Uniting in a common goal involving more people leads to greater and more visible results, and this is achievable by providing more information about the possibilities.

The appropriate utilization of natural resources to create sustainable alternatives for energy production is a step in our pursuit of a better and higher quality of life. Good examples in this direction include the use of biomass in the form of forest and agricultural waste and wood for direct burning, solar energy, geothermal energy, and aerothermal energy. Although still in an early stage, possibilities for harnessing the energy from waves in seas, lakes, and reservoirs are also being explored. The main focus is on improving the quality and accessibility of data, cooperation in data exchange, assessing and monitoring biodiversity, and finding suitable opportunities for their application. There is increasing talk at the national level about the so-called "one-stop-shop" – a single point that offers multiple thematically related services, providing access to comprehensive information on programs and activities in the field of improving energy efficiency in Bulgaria.

Natural resources and energy efficiency


The human-generated waste is becoming an increasing threat to the ecosystem of the Black Sea. The majority of solid waste in the marine environment consists of materials that take decades to degrade. According to studies, 80% of this waste originates from land-based sources, with only 20% being the result of various economic activities at sea. Marine waste is not clearly visible to our society, which largely remains unaware of its existence and its detrimental impact on the marine ecosystem. Approaches to creating good practices for marine ecosystem conservation may include preventing waste production, improving household waste collection systems and waste management in coastal areas, establishing a comprehensive, synchronized monitoring system to identify waste accumulation zones, conducting awareness campaigns for public education, and engaging citizens in each of the above topics.

Climate and Climate Change Climate change is the greatest threat to nature and humanity in the 21st century. According to data from temperature measurements, it can be observed that the 15 warmest years on Earth have occurred in the last 20 years. In Bulgaria, we are witnessing increasingly frequent and longer periods of drought, followed by hurricane storms, severe floods with destruction and casualties, and other natural disasters. Taking adequate actions to improve environmental conditions by preventing risks of floods, landslides, and erosion, especially characteristic of coastal areas, is extremely important. Climate change can lead to new, even more extreme climatic events, jeopardizing the material wealth and lives of many people. Coordination and management of risk prevention will contribute to ensuring a sustainable and secure environment for people's lives and health, as well as for the development of tourism and the economy.

  • For each of the described categories, a score ranging from 4 to 20 points is assigned.


The hackathon is a competition, and as such, it concludes with the selection of the best teams by the jury.

The first three teams will be awarded certificates and prizes from a total cash prize pool of 3000 BGN:

First Place – Cash prize of 1500 BGN for the entire team.

Second and Third Place – Material prizes for each participant in the team.
