Over the last 50 years, conventional fossil-based plastics have become an integral part of our everyday lives. Apart from their low production costs, this is due to a number unique properties, including durability, strength, lightness, electrical and thermal insulation, resistance chemicals corrosion. The has increased 1.5 million metric tons in 1950 359 2018. Of total, 61.8 were produced Europe. There are various problems associated with plastic use disposal that pose serious threat both...
The world production of plastic exceeded 360 million tonnes in 2020 alone, a considerable amount which is not properly disposed of. significant pressures and damages posed by conventional to human environmental health suggest that alternatives are urgently needed. One them "bioplastic", defined as bio-based (or not) biodegradable. This paper reports on study the perceptions bioplastics among consumers 42 countries identify their levels information concerns. results most respondents have...
In this study, an evaluation of food waste generation was conducted, using images taken before and after the daily meals people aged between 20 30 years in Serbia, for period 1 January 31 April 2022. A convolutional neural network (CNN) employed tasks recognizing meal estimating percentage according to photographs taken. Keeping mind vast variates types available, image recognition validation items present a generally very challenging task. Nevertheless, deep learning has recently been shown...
Qualitative or quantitative description of the future by developing scenarios is a key method when taking long-term view, e.g., up to 2050. Previously time frames covered have usually been no more than 20 years. This period can be too short for achieving goals when, example, testing watershed management plans. paper an attempt introduce and illustrate potential Story-and-Simulation methodology Fuzzy Cognitive Mapping drawing qualitative semi-quantitative Lake Peipsi, one largest surface...
This study evaluated the impact of socio-economic and lifestyle changes on nutrient loads water quality in Haapsalu Bay, Baltic Sea between 1995-1996 2003-2004. Monthly monitoring data four rivers discharging to bay seawater at five sea stations were used. External input TN remained almost unchanged during period despite somewhat higher riverine load that was explained by intensified agriculture. The TP decreased approximately 45% due decrease river point source loads. Point sources...
The nutrient content in streams and rivers depend on many interacting processes such as hydro-geographical conditions land use practices. aim of this study was to investigate the current status Estonian determine any trends concentrations total nitrogen (TN) nitrate-nitrogen (NO3-N) between 1992 2013. This involved 43 monitoring sites 32 Estonia. temporal were assessed using partial Mann- Kendall (PMK) test, which adapted account for influence water discharge. Most studied did not show trend...
This study aimed to develop scenarios for a further decrease of point source nutrient load in Estonia achieve the reduction target levels set up by HELCOM Baltic Sea Action Plan produced 2007. A possible total phosphorus (TP) and nitrogen (TN) has been assessed based on requirements Estonian EU legislation as well recommendations. Scenarios were developed four urban pollution classes with different waste water quality at outlet wastewater treatment plant (WWTP). The results revealed that TP...
The task of this study is the comparative analysis diffusion process Blockchain into national higher education systems as well best-practice examples. It part EU Erasmus+ project "BlockWASTE", which has its overall objective to promote application in municipal waste management through development targeted university curricula and plans on Circular Economy Blockchain, training manuals other educational tools. With goal mind, first question be answered where there a need for Blockchain. This...
The aim of this comparative study is to document the status quo in digitalization ofmunicipal waste management EU countries, order ultimately examine which areasthe implementation blockchain solutions makes sense.Blockchain only a database solution that allows trace and track transactions within awaste chain, transfer digital assets from peer use smart contracts forautomating processes. But for application like blockchain, decisive factoris course automatic collection data via...
