Study on the factors influencing municipal solids waste generation in China by multiple statistical analysis
The factors influencing municipal solids waste generation in China is present in this study by multiple statistical analysis. The 12 items was chosen to investigated, including GDP, per capita GDP, urban population, the proportion of urban population, the area of constructed urban, the area of paved roads, the area of urban gardens and green areas, the number of the big cities, annual per capita disposable income of residents, per capita annual consumption expenditure, total energy consumption and annual per capital consumption for households.
Three new dimensions to be found by principal components analysis (PCA).Component 1-Economy and urban development; Component 2-Population; and Component 3–Energy consumption; the three components together account for 97.8% of the initial variance (KMO=0.736; Bartlett’s test P-value=0.000; Cronbach’s alpha coefficient ranging from 0.68 to 0.76). The results show that economy and urban development items are important factors influencing MSW generation, but the relationship between gross domestic product (GDP) growth and production of MSW was not as clear-cut as assumed in China. For the first time, the energy consumption is considered as a main approach to influencing the MSW generation. The annual MSW quantity variation was also investigated by cluster analysis.

Wertstoffhof 2020 - Neuorientierung von Wertstoffhöfen
© ia GmbH - Wissensmanagement und Ingenieurleistungen (4/2015)
Im Jahr 2014, zwanzig Jahre nach dem durch das Bayerische Staatsministerium für Landesentwicklung und Umweltfragen organisierten Wettbewerb „Der vorbildliche Wertstoffhof“, ist es sicher angebracht, sich dem Thema erneut zuzuwenden. Was ist aus den prämierten Wertstoffhöfen der Preisträger in den jeweiligen Clustern geworden? Wie hat sich das System grundsätzlich entwickelt? Wo geht es hin, wenn man die gesellschaftlichen Anforderungen aus demografischer Entwicklung, Ressourcenschutz und Klimarelevanz betrachtet?

Municipal solid waste (MSW) management is considered a public service, roviding citizens with a system of disposing of their waste in an environmentally sound and economically feasible way. The amount and composition of waste generated comprise the basic information needed for the planning, operation and optimisation of waste management systems.
Household’s size affecting solid-waste production in municipality of Volos, Greece
© Aristotle University of Thessaloniki (6/2009)
Solid-waste generation differs from region to region since it depends on many socioeconomic and other factors. Quantity and composition of generated waste are essential in order to plan a municipal solid waste management strategy. Therefore it is necessary to estimate solid-waste generation for a given region as well as its correlation with the socioeconomic factors. Household’s size is under investigation in the present paper, in order examine whether there is an effect on solid-waste generation.
Aktuelle Situation der Abfallwirtschaft in Mecklenburg-Vorpommern - Nord-Ost-Deutsche Abfallantworten

„Aktuelle Situation der Abfallwirtschaft in Mecklenburg-Vorpommern – Nord-Ost-Deutsche Abfallantworten“ – so lautet das Thema meines Vortrags. Zugegeben, ich war etwas verwirrt, was die „Nord-Ost-Deutschen Abfallantworten“ beinhalten sollten. Aber aufgrund der Struktur Ihrer Landesgruppe Küstenländer ist es für Sie vielleicht doch von besonderem Interesse, welche Sicht wir in Mecklenburg-Vorpommern auf heiß diskutierte Fragen in der Abfallwirtschaft haben.
