Asbestos is a general name applied to a group of silicate minerals which naturally occur in fibrous form. It is a natural mineral widely used in the past, especially in the construction industry. Despite its good performance properties, it is currently known that asbestos has carcinogenic properties. The problem of storing asbestos wastes is significant worldwide. This especially applies to countries where the production and use of asbestos products is prohibited by law. One of the possible methods of proceeding a...

Cities in the Czech Republic and nearby Central Europe usually have a very long tradition. This post shows changes in the long run in the scope and function of green and water areas in selected municipalities. Most of the cities in the region were founded in the Middle Ages, from the 10th to the 13th century. At this time, the issue of water and green cities was directed purely at the utility function of drinking water and food supply. The exception at this time was only the gardens of noble and tin buildings. Ove...

Miyawaki-forest is a well-known method to create small forest quickly in urban conditions. It works with native woody species that are densely (4-5 pcs/m2) planted together after topsoil changing in a quite small area. The first Hungarian Miyawaki-forest was introduced in Taban, 2021. It planted with 9 native species (Acer platanoides, Acer campestre, Carpinus betulus, Crataegus monogyna, Euonymus europaeus, Pyrus pyraster, Ulmus laevis, Sorbus torminalis and Quercus robur). The area is 40 m2. Soil was changed up ...

Today, it is possible to work with a wide range of freely available data, often on a daily basis. These data can be used to create an early warning system for estimating the approximate hazard. It can also be used to develop models of long-term catchment behaviour. Most applications are generally carried out on catchments larger than 200 km2. For this reason, areas between 20 and 350 km2 were selected to test the hypothesis using models based on machine learning methods. How good results can be achieved when using...

Even today, factories and production systems are primarily planned using established methods from lean production, developed in the 1990s, which only partially address sustainability. Industrial production significantly impacts climate change; in Germany, for instance, 70% (9.1 million TJ) of the primary energy requirement of 13 million TJ comes from industry, and around 28% of annual new land use is attributed to industrial expansion and new construction. This situation is no longer viable, given the European Com...

Biopolymer-based packaging materials are increasingly favored for their eco-friendly and biodegradable properties.
