As a result of an increased consumption, waste volumes has grown steadily throughout the 1900s, and this puts great demands on an efficient and ecological sustainable waste management on both local and national level. In order to evaluate collection and disposal of household waste, a large number of Sweden´s municipalities are using waste analyses. The overall aim of this study has been to summarize and assess results from waste analyses executed in Härjedalen´s municipality during the years 2007-2011.The evaluation has given information about the household waste´s composition, quantity and change in time. The report´s objective has been to create a basis which the municipality can use in planning of future information efforts and other measures, and give some proposals on how these can be designed and targeted. Therefore, the report also highlights research on motivations factors that affects environmentally conscious behavior such as recycling, and how different instruments like information can be used to promote this.

Background: The demand for sending letters, in the traditional aspect, has decreased because of electronic sources which have replaced a big part of letter communication. The Postal Service constantly strives for lowering costs and due to the changeable demand, a greater awareness is required regarding recourses and their usage. The previously mentioned measures in combination with commonly occurring quality issues during the collective process at the letter terminal in Alvesta would be improved by applying a lean-perspective to the process. A first step towards saving of time is to apply the ?value stream mapping?-method on the collective process for small and large letters.Purpose: To map the process of collection for small and large letters to be able to identify waste of recourses and furthermore give suggestions on how the Postal Service would be able to reduce the waste of recourses identified.

Every year 67000 tons of food is wasted by Swedish retail stores. The waste implies financial losses for the retailer and it has a huge impact on the global environment. Reducing in-store food waste is thus a win-win situation for both retailers and society. The most effective way to reduce waste is primarily by optimizing the logistics of supply, but customers expect a store with a wide range of products and stuffed shelves. Thus there will always be products about to expire.

The waste fractions offered to households in Sweden differ depending on where you live. The responsibility for the waste are grounded by the Swedish law where the municipality are responsible for the collection of household waste and FTI are responsible for collecting all packages and papers that the households sorts out. A new waste regulation is under consideration where the responsibility for the household waste may change. The bulky waste from households is collected at recycling centers where the households leave it in different containers for different fractions. These recycling centers are formed different and the fractions offered in them also differ depending on in what municipality they are located.

The world?s growing need for energy together with a desire to ward off the worst consequences of global climate change has resulted in a never seen desire to invest resources in renewable energy sources. Biogas production through anaerobic digestion is one of those growing energy sources. In Sweden there are over two hundred plants that uses this biological process to break down organic substances while producing carbon dioxide and the energy-rich gas methane.This master?s thesis has focused on development of the mixture of different organic substances that is treated at a specific plant, namely Mosserud biogas plant.

People of the modern world consume more than they ever used to do. Because of the close correlation between consumption and the amount of waste, the waste volume is also expected to increase. The purpose of this study is to examine if some measures in the recycling process from Sweden could be implemented in Indonesia. In fact, Indonesia is one of the countries in which the waste management system is struggling. Tetra Pak, one of the world leading producer of food packaging, is studied in this report.

Economy and environment has for a long time been studied separately and seen as incompatible. With a growing society and increasing pressure on environmental issues the need of a new economy with the environment included is necessary. This study examine if European Union´s picture of the waste hierarchy match the reality. Since the purpose with the waste hierarchy is to benefit environmental and economy. A survey was made over Käppalaförbundets waste from 2013, to see where the waste falls in the waste hierarchy.

This paper deals with challenges associated with handling scrubber waste in the port of Karlshamn and what various industry partners are doing to meet this growing demand. The main challenges have been the proportion of ships with scrubber, the amount of generated waste and waste characterisation. An understanding of these factors has been crucial in order to ascertain the aim of this study, which has been made with calculations based on leading manufacturer?s scrubber analyses and with an estimation of the quantity of ships with scrubber by examining AIS data from the Port of Karlshamn. In order to calculate the quantity of scrubber waste two different scenarios were established, which in turn produced two different outcomes.

The goal of this master thesis project was to develop computer models of some plausiblepretreatment techniques and to assess the potential benefits/costs of using pretreatment andanaerobic digestion for waste management of organic waste from a system perspective. Forthis purpose a computer program called ORWARE has been used. ORWARE (organic wasteresearch) is a program for making life cycle assessments of waste management. As the mainpart of the project work the ORWARE system has been provided with three new models ofpretreatment techniques. The additions consist of: One model of pretreatment with ultrasound,one model of thermal hydrolysis and one model of a screw press.

The research in this paper aims to producing a home version machine thatcan dry and make biological waste into compact pellets. This product ismade primarily for those who want to improve the environment and reducethe energy consuming process of separating the biological leftovers fromother waste in the large processing plants and save money due to reducedpickups of waste. Since there is no commercially available product thatdoes what we want to achieve we had to start from the beginning with boththe design and the mechanical aspects. The result is a machine, that fits inour homes, and in an easy and inexpensive way reduces the amount ofbiological waste that needs to be collected by the public wastetransportation system. This is done without reducing any of the energy inthe waste and it can still be used to compost or by large-scale plants that usethe waste to make electricity.

Outside of many Swedish households today, you will find a typical green wastecontainer. This container has not changed since its introduction, despitecomplaints about foul-smelling and its impractical system. Even if the system usedtoday, still is the most optimal choice, there is a lot of newly developedalternatives out there.Its purpose is to get a broader perspective on how a waste management systemcan be developed into a working, land efficiently and aesthetically pleasing systemof humans and the environment in a small residential area.The authors treat the residential area of Jära, Ekhagen, in Jönköping, which ismanaged by JM AB as a problem area in regards to waste management.The issues raised by the authors are the different waste management systems usedin the corresponding areas of the world, how to apply technical andenvironmental as well as the waste management facilities from financial aspects.In the process, the methods used were literature reviews, case studies and aninterview. The case study was done through a modeling of waste managementsystems in the area Jära and an interview was conducted with the company Envacworking with vacuum systems. Studies have been made by different systems n theareas around the world.The results show that using directives and guidance will reduce the environmentalimpact done without replacing the traditional system.

As a small and land scarce country, effective waste management is ofoutmost importance in Singapore. In this study the production of biogasthrough anaerobic digestion from the organic fraction of municipal solidwaste (OFMSW) was compared to incineration of the waste. At the momentalmost all of the OFMSW in Singapore is incinerated. Three differentscenarios were compared to the reference scenario (incineration): one with alarge scale biogas plant that can treat half of all OFMSW in Singapore, onewith a medium scale biogas plant about 15 times smaller than the large oneand one with a small scale biogas plant that can treat waste from e.g. ashopping center or a food center.By using life cycle assessment (LCA) the different scenarios were comparedin terms of global warming potential (GWP), acidification, eutrophication,energy use and land use.

The purpose of this study was to examine how food managers of Östergötland County disucss around their possibilities of reaching the government´s orientation towards 25 per cent of the food - procured, prepared and cooked in the school meal - coming from certified organic production. The study was a cross-sectional study in wich a qualitative approach was used. The sample consisted six food managers in Östergötland. Data processing was done through a semantic content analysis.  The result showed that involvment and intrest were significant factors for the introduction of organic food in the school meal. The three municipalities with the highest percentage of organic food used the SMART - concept.

This report is the result of a thesis work carried out on the Risifrutti production at the company Procordia Food AB. The thesis is at a master level and is the final work for the author to receive a Master of Science in Innovative production at Mälardalen University. The thesis comprises 30 credits and has lasted for 18 weeks. The thesis is mainly a research on whether it is possible to perform an Environmental Value Stream Map (E-VSM) in a food processing industry and an evaluation if the tools E-VSM and Green Performance Map (GPM) are useful in this type of industry. An extra part to this research is to use the results from the E-VSM and give Procordia Food AB information on improvement potentials in the Risifrutti production. The author has found it difficult to collect some of the quantitative data to the E-VSM, mainly regarding energy, but by using the Value Stream Mapping (VSM) tool and other Lean tools the author was able to identify and quantify several wastes in the Risifrutti production. Recommendations for improvements based on these wastes have been given to the company. In the research part of this report the utility of the Value Stream Map, Environmental Value Stream Map and Green Performance Map in a food processing industry have been analyzed. The author has found that the Value Stream Map has been a useful tool since waste and unevenness in the tact of the production has been identified. The Environmental Value Stream Map and the Green Performance Map are also great tools when a company wants to analyze their environmental impact and then invest in environmental improvements. However, no profound energy analyzes has been done in the Risifrutti production because of the lack of energy meters for steam, electricity and compressed air in the production lines..

Construction waste from the housing industry includes all unnecessary consumption of building materials. The definition of construction waste is construction materials that has not been built in and becomes waste. Constructions waste can be divided into two types of contributions: operational and work site contribution. Some of the common construction materials in housing industry have such low usage level as 75 % and the rest becomes construction waste. Low usage of construction materials creates unnecessary costs and has a major environmental impact.
