The progress towards climate neutrality and sustainable development of the national economy is increasingly challenging. At the European Union level, the target for renewable energy set by Directive 2018/2001 is at least 32 %. Industry is not only an essential part of the national economy but also a field of opportunity for increasing the share of ...

In current study UV light and visible light activated photocatalytic inactivation treatment was applied to the less commonly studied subjects, namely bacteriophages PRD1, T4 and their mixture. By using UV light irradiation and high efficiency P25 TiO2 photocatalyst powders it was demonstrated that individually and in mixture PRD1 bacteriophage is p...

Cooking oils are widely used in food preparation. During cooking, harmful compounds are formed in oils, therefore utilization of used cooking oils (waste cooking oils) is limited. Single cell protein (SCP) is dietary protein, which can be produced from various protein-rich microorganisms that are capable of utilizing industrial by-products such as ...

The use of flue gas condensers proved to be effective in increasing boiler efficiency and achieving primary energy savings. The transition to the 4th generation district heating will lead to temperature reduction in district heating networks. The aim of this study is to determine the effects of the reduction in the district heating return temperatu...

Building energy demand for heating and cooling has a complicated relationship with different environmental conditions surrounding the building sector. Many projects aiming to improve thermal performance in existing buildings in Jordan suggest that roof insulation will improve thermal performance. In this study we try to prove that minimizing buildi...

Large-scale heat pumps (HPs) and refrigeration plants are essential technologies to decarbonise the heating and cooling sector. District heating and cooling (DHC) can be supplied with low carbon footprint, if power generated from renewable energy sources is used. The simultaneous supply of DHC is often not considered in energy planning, nor the cha...
