Social acceptance of littering behaviour has changed in the recent decades, with rapidly increasing public awareness about the human health and biodiversity impacts that can result from waste-mismanagement. Littering has an important impact on landscape and overall environment. It is of vital importance to assess existing littering sources and to try to limit them at their source. During recent years European Union (EU) has significantly strengthened the waste management requirements. In terms of newer Member States it meant – inventory of the existing system, closure and recultivation of the sub-standard landfills, development of new infrastructure, using best available technologies and, of course implementation and development of separate waste collection system. In order to ensure higher quality recycling, requirements to sorted waste collection become higher. The authors see one of the solutions – implementation of the deposit refund system (DRS), especially taking into account that both plastic beverage bottles as well as bottle caps have been identified within top 10 single use plastic found in the marine litter. The research is based on the benchmarking and statistical data analysis. As the result of the research, the authors propose implementation of DRS as a solution both to Latvian waste management issues and as a tool to improve landscape from the environmental aspects.
Items on waste generation in the Riga city are analysed. Short presentation of the study methods is provided, and achieved results are presented. Three different dwelling areas have been investigated: multi-apartment houses with and without of waste shoots and private houses. Comparison of obtained results with similar ones have been got abroad is included. It is stated that average solid household waste generation in the Riga city is 199.2 kg / capita / year or 1.52 m3/ capita / year. Morphological composition of waste is analysed, and it is stated that following types of waste are dominating: putrescible waste, paper-cardboard, glass and plastics. Conclusion is done that generated waste amount strongly depends on value of the gross domestic product is done, i.e. increase of waste amount generated per capita maybe expected in the Riga city.
-Municipal waste management is an activity that decreases environmental hazard and impact on human health, on the other hand, it is still linked with possible technogenic risks during management processes. The paper is focused on the assessment of low potential risk with the high impact on technogenic safety -waste inflammation at different waste management stages. The paper performs an assessment of most common inflammation causes and offers a variety of activities to be undertaken to eliminate or decrease such risks. As one of the solutions in order to minimise possible inflammation risk, the authors advise improving sorting system so that the fractions that are exposed to inflammation are sorted out at the early stages and managed in the best possible way.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
