The main goal of this project was to develop some sort of a diverter for pipestransporting waste in a vacuum system. This unit was supposed to be both cheap andeasy to serve/exchange worn out parts. With a limited space to install the pipeexchanger, the challenge was to keep it as compact as possible without constructingbends with to small radius or to sharp angles as this would wear out the system a lotfaster than planned. The system was also supposed to be able to handle clothes andscrubs from hospitals. Having too much sharp edges or angles would tear the clothesapart. We were also limited to the building plan. The diverting unit had an inlet thatwas required to be aligned with a hole in the wall that was currently being molded tofollow the already thought out flow. The two outlets also had to align with the rest ofthe piping system, to make sure that the containers on the loading bay did notbecome offset from the original position. This would cause problems with the spacefor the trucks that retrieve them in the building.The result from this thesis is a solution that is adaptable for different situations, and indifferent scales. This is really beneficial as the company has two different sizedsystems and will be able to use the same module for all of their constructions. It doesnot matter whether the construction is mounted horizontally or vertically.Throughout the designing process there were aspects about costs, simplicity and lastbut not least function that was taken into account. There are a lot of things that isdependent of these three mayor aspects. As for design, a more esthetic design, makesit more costly to produce. And having unnecessary weight in the construction affectsboth the simplicity as in it gets harder to mount into place and serve, as well as anunnecessary cost. Keeping it simple was also required as we had to keep it compact.

Municipal waste management aims to collect waste from people and businesses in a sustainable manner. Today's waste management relies on an old container system which is simple and flexible. There are some problems with this type of management for both waste generators and collectors. The working environment is not the best for municipal waste collectors, there is heavy lifting and risk elements in the handling of containers and bags. There are also risks involved with heavy vehicles moving in sensitive areas such as residential areas and around schools. Forecasts show that most urbanized areas are expected to grow further for some time. This creates problems of increasing waste volumes, thereby increasing traffic. This makes it interesting to evaluate new and existing solutions of the collection and transportation of municipal solid waste. The study aims to identify the current municipal solid waste management theories and evaluate the opportunities that exist to develop the theory forward with focus on the collection in urban areas. The study intends to review whether it is economically feasible to implement automated vacuum systems in existing infrastructure. The theory shows that it is often possible to implement this in new construction projects, but the research is vague and inadequate regarding implementation in existing infrastructure. The case study examines whether implementation of an automated vacuum collection system is possible in central Gothenburg. The analysis assesses the financial feasibility of the implementation. Specifically, the unused surface of the refuse rooms can be utilized differently, thus reducing the costs that arise initially. The study shows that it will be profitable to implement an automated vacuum system in the study area since the initial investment can be offset through the alternative use of the floor space in the waste rooms. The study results suggest that other areas in existing infrastructure can implement similar solutions without economic losses.

Dagens sophantering är inte hållbar då exploateringen blir tätare och samhällenabelastas med mer mängd avfall. För en hållbar utveckling så måste sophanteringen blimer miljö- och funktionssmart.Syftet med rapporten är att undersöka olika sopsugsmodeller för olika ändamål.Undersökningen har sin utgångspunkt följande områden: Sopsugsystemetsuppbyggnad för stationär och mobil anläggning, komponenter i systemen, hållbarutveckling, tillvägagångssätt för nyproduktion respektive ROT-arbeten,användningsområden och intervjuer med kommuner om befintliga system.Informationen om sopsugsystemen har tagits dels från Logiwaste AB genomintervjuer, föredrag, dokument och fem intervjuer med kommuner för att få en verkliginblick hur systemen fungerat.För att kunna genomföra en byggnation av en sopsugsanläggning har vi analyseratbyggtekniska metoder för att uppnå ett renare och hållbart samhälle.Dagens sophantering är inte hållbar för framtiden. De modernasopsugsanläggningarna är ett alternativ till en utvecklad och hållbar sophantering.Vid en fortsatt läsning av rapporten kommer läsaren få en fördjupning i områdenasom tagits upp. / Today's waste disposal is not sustainable as exploitation becomes denser and societiesare loaded with more waste. For a more sustainable development, waste managementneeds to be more environmentally and functional.The purpose of the report is to investigate different waste disposal systems fordifferent purposes. The study is based on the following areas: The contexture of wastedisposal system for stationary and mobile installations, components in systems,sustainable development. New production, renovation and extension approaches.Applications and interviews with municipalities about existing systems.The information about the waste disposal systems has been taken from Logiwaste ABthrough interviews, lectures, documents and five interviews with municipalities to geta real insight into how the systems worked.In order to carry out a construction of a disposal systems we have analyzed buildingtechnology methods to achieve a cleaner and sustainable society.Today`s garbage disposal is not sustainable for the future. The modern automaticwaste collection facilities are an alternative to developed and sustainable wastemanagement.At a further reading of the report the reader will get an indentation in the areasmentioned.
