Waste is not only an environmental problem, but an economic loss because Romania recycles only a small part of municipal waste. The use of atmospheric pollutant dispersion models has become necessary due to cost-efficiency reasons, given the limitation of fixed measuring points/stations for these pollutants. The paper studies the dispersion of PM10 dust particle pollution in the landfill?s area of influence, depending on wind direction and speed. Simulations are based on measurements of suspended particles, carrie...

In 2019, the Slovak Republic committed to start implementing actions aimed at achieving carbon neutrality. The carbon neutrality is to be achieved by 2050. The selection of building materials in the project planning phase is considered to be one of the actions. When choosing a building material, the client will decide not only on the construction cost, but also on the environmental cost of building material. This environmental cost takes into account the carbon footprint from the initial origin of the building mat...

Pollution and its effects on the environment have been at the centre of debates on the global stage, with growing concerns from researchers and the public. A major source of pollution is polymeric materials, which are increasingly used in various industries because of their similar properties to metal. If, in the case of polymeric thermoplastics materials we have recycling and reusing technologies when they reach the end of their lifespan or they break, not the same can be said about polymeric thermosetting materi...
