does food sorting prevents and improves sorting of household Waste a case in sweden
Journal of Cleaner Production, 2015Co-Authors: Jurate Miliuteplepiene, Andrius PlepysAbstract:This paper analyses household behaviour as response to changes in Waste management systems. The paper discusses the results of a case study from Vellinge municipality (Sweden), where the introduction of separate food Waste collection is thought to have a role in reducing the total amount of household Waste and improving the sorting of packaging Waste. The study relies on data from official Waste Statistics and a survey of 117 municipal residents focusing on households' perceptions, attitudes and self-reflected changes in Waste sorting behaviour. The respondents mentioned the increased environmental awareness and the convenience of food Waste sorting among the primary reasons for the perceived changes in personal Waste sorting routines. The study also tested the significance of other variables, such as income, employment, economic activity, socio-demographics, infrastructure, Waste tariffs, illegal dumping, and awareness raising campaigns. Most of the variables were static and none showed sufficient correlation to the observed reduction of Waste collection rates and the improvements in sorting other Waste fractions. The analysed case had particularly high income levels, which were the main dynamic variable under study. The analysis suggests that we may be observing an example of a decoupling between economic growth and Waste generation rates. This observation is explained by the Kuznets phenomena and it is being discussed in this paper. (Less)

solid Waste management practices and review of recovery and recycling operations in turkey
Waste Management, 2003Co-Authors: E Metin, A Erozturk, C NeyimAbstract:This paper provides a general overview of solid Waste data and management practices employed in Turkey during the last decade. Municipal solid Waste Statistics and management practices including Waste recovery and recycling initiatives have been evaluated. Detailed data on solid Waste management practices including collection, recovery and disposal, together with the results of cost analyses, have been presented. Based on these evaluations basic cost estimations on collection and sorting of recyclable solid Waste in Turkey have been provided. The results indicate that the household solid Waste generation in Turkey, per capita, is around 0.6 kg/year, whereas municipal solid Waste generation is close to 1 kg/year. The major constituents of municipal solid Waste are organic in nature and approximately 1/4 of municipal solid Waste is recyclable. Separate collection programmes for recyclable household Waste by more than 60 municipalities, continuing in excess of 3 years, demonstrate solid evidence for public acceptance and continuing support from the citizens. Opinion polls indicate that more than 80% of the population in the project regions is ready and willing to participate in separate collection programmes. The analysis of output data of the Material Recovery Facilities shows that, although paper, including cardboard, is the main constituent, the composition of recyclable Waste varies strongly by the source or the type of collection point.

Analys av möjligheter för miljövänlig och effektiv hantering samt reducering av restprodukter från Scanias motortillverkning
2020Co-Authors: Al-sabti Noor, Cederwall EmmaAbstract:At Scania's engine manufacturing in Södertälje, manufacturing processes are used for designing and machining engine components. In the manufacturing of these engine components, residual products are formed such as millings, Wastewater and residual emulsion. Scania's internal goal is to reduce the amount of non-recyclable Waste by 25% from 2015 to 2020. Engine manufacturing aims to handle all Wastewater and residual emulsion at Scania's internal Waste management facility "by 2018". The thesis examined technical possibilities of reducing the amount of residual products from the engine manufacturing, as well as investigating the potential for improvement of residual product management. Qualitative and quantitative methods, such as interviews and data processing of Waste Statistics have been used in the study. A solution proposal has been developed for reducing and managing millings from the production. For reduction and management of Wastewater and residual emulsion, four different solutions have been developed. The solution proposals have been analyzed based of economic profitability, Waste reduction and applicability. For the reduction and managing of millings, the most qualified technique was briquetting. The study shows that the amount of millings produced at the crankshaft department can be reduced by 100% and to invest in a briquetting system is financially profitable after 2,3 years if the briquettes are recycled internally at Scania. For Wastewater and residual emulsion management, there is a potential for improvement at the engine manufacturing to reduce external handling. Effciency enhancement and development of processes and working methods for engine manufacturing is a cost-effective solution to improve the management of residual products. The investigation shows that investing in a buffer system is an effective solution for improving the management of Wastewater and residual emulsion, with regard to a more leveled Waste flow. The two solutions are both economically profitable and environmentally beneficial in the form of less external handling. Engine manufacturing has the opportunity to reduce the amount of Wastewater by investing in staff for the maintenance and control of washing machines. The investigation also shows that the amount of Wastewater could be further reduced by investing in measuring and monitoring systems for the final washers. The two solutions will generate an economic profit in the form of improved cleanliness of the engine components, reduced amount of Wastewater, as well as fewer external handlings

Analysis of opportunities for environmentally friendly and efficient handlingand reduction of residual products from Scania's engine manufacturing
SLU Institutionen för energi och teknik, 2020Co-Authors: Cederwall Emma, Al-sabti NoorAbstract:På Scanias motortillverkning i Södertälje används olika tillverkningsprocesser för utformning och bearbetning av motorkomponenter. Vid tillverkning av motorkomponenter uppstår restprodukter i form av slipmull, spillvatten och restemulsion som Scania måste hantera. Scania har som internt mål att reducera mängden icke-återvunnet avfall med 25 % från 2015 till 2020. Motortillverkningen har som enskilt mål att allt spillvatten och restemulsion ska hanteras på Scanias interna avfallsanläggning by 218. Examensarbetet har undersökt de tekniska möjligheterna att reducera mängden restprodukter från motortillverkningen samt undersökt förbättringspotentialen för hantering av restprodukter. Utgångspunkten i arbetet har varit kvalitativa och kvantitativa metoder i form av intervjuer och sammanställning av avfallsstatistik. För reducering och hantering av slipmull har det bearbetats fram ett lösningsförslag. Vad gäller hantering samt reducering av spillvatten och restemulsion har det tagits fram fyra olika lösningsförslag. Lösningsförslagen har analyserats utifrån aspekter såsom: ekonomisk lönsamhet, avfallsreducering och applicerbarhet. För reducering och hantering av slipmull ansågs den mest kvalificerade tekniken vara brikettering av slipmull. Undersökningen visar att mängden slipmull som bildas på vevaxelavdelningen kan reduceras med 100 % och att investera i ett briketteringssystem är ekonomiskt lönsamt efter 2,3 år om slipmullsbriktetterna återvinns internt på Scania. Vad gäller hantering av spillvatten och restemulsion visar studien på att det finns förbättringspotential på motortillverkningen för att minska externa hanteringar. Effektivisering samt utveckling av processer och arbetssätt på motortillverkningen, är en kostnadseffektiv lösning för att förbättra hanteringen. Undersökningen visar även att investering i en buffertanläggnig har en effektiv lösning för att förbättra hanteringen av spillvatten och restemulsion, med avseende på ett mer utjämnat avfallsflöde. De två lösningförslagen för hanteringen är både ekonomiskt lönsamt och miljömässigt lönsamt i form av färre externa hanteringar. Motortillverkningen har möjlighet att reducera mängden spillvatten genom att investera i personal för skötsel och kontroll av tvättmaskiner. Undersökningen visar även att mängden spillvatten skulle kunna reduceras ytterligare vid investering i mät- och övervakningssystem för sluttvättarna. De två lösningsförslagen kommer generera en ekonomisk vinst i form av förbättrad renhet på motorkomponenterna, reducerad mängd spillvatten, samt färre externa hanteringar.At Scania's engine manufacturing in Södertälje, manufacturing processes are used for designing and machining engine components.

towards a more circular construction sector estimating and spatialising current and future non structural material replacement flows to maintain urban building stocks
Resources Conservation and Recycling, 2018Co-Authors: Andre Stephan, Aristide AthanassiadisAbstract:Abstract Humans are extracting and consuming unprecedented quantities of materials from the earth’s crust. The construction sector and the built environment are major drivers of this consumption which is concentrated in cities. This paper proposes a framework to quantify, spatialise and estimate future material replacement flows to maintain urban building stocks. It uses a dynamic, stock-driven, and bottom-up model applied to the City of Melbourne, Australia to evaluate the status of its current material stock as well as estimated replacements of non-structural materials from 2018 to 2030. The model offers a high level of detail and characterises individual materials within construction assemblies for each of the 13 075 buildings modelled. Results show that plasterboard (7 175 t), carpet (7 116 t), timber (6 097 t) and ceramics (3 500 t) have the highest average annual replacement rate over the studied time period. Overall, replacing non-structural materials resulted in a significant flow of 26 kt/annum, 36 kg/(capita·annum) or 721 t/(km2·annum). These figures were found to be compatible with official Waste Statistics. Results include maps depicting which material quantities are estimated to be replaced in each building, as well as an age pyramid of materials, representing the accumulation of materials in the stock, according to their service lives. The proposed model can inform decision-making for a more circular construction sector.
