The purpose of this report is to increase the awareness about the problem that occur when the waste hierarchy is applied to management of contaminated land. The work with remediation of contaminated land in Sweden is part of the efforts towards reaching the national environmental objectives. Therefore a subsidiary aim is to analyze how this influences the prospects of reaching the objectives. The work consists of two parts; a case study and a comparative literature study that focus on England, the Netherlands and Sweden. The case study is intended to provide a practical perspective through a comparison of the climate impact from two methods.

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.

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 concept of sustainable development has been pervasive in recent years and many organizations choose to implement sustainability and adapt their activities accordingly. The purpose of this study have been to explore how a collaboration on the use of waste materials may look to analyze what influences cooperation. A case study has been carried out examining a Swedish state regional project aimed at creating partnerships between actors and utilizing textile waste with the help of design. The study was conducted using qualitative methods and the collection of data has been done through interviews and by examining documents. The results show that there are seven key factors that affect cooperation: expectations, commitment, internal communication, a strong non-profit actor, individual treatment, personal networks and the diversity of actors.

The aim of this essay is to examine the handling of plastic waste on a local level in the three municipalities of Gothenburg, Malm? and Stockholm. This is achieved with the help of guidance within the theory of Multi-level Governance. By applying the EU directive 2019/904, about disposable plastic, and examining the global plastic problem, the efforts to promote sustainable use, and recycling of plastic, is analyzed. The method involves a qualitative content analysis, where the 2022 waste plans of the three municipalities, ?Sveriges handlingsplan f?r plast? by the Government Office, and the 2019/904 EU directive constitutes the base of the study.

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.

This thesis has identified and studied measures to allow for reduced use of electricity in a waste incineration plant in western Sweden. The energy extracted from the waste at the powerplant is utilized and sold in form of electricity and heat. Technical and environmentally the combined heat and power plant is by today's standards among the leading waste incineration plants in the world. The owners are constantly striving to improve the efficiency of the waste incineration plant. They have seen the opportunities for savings in reducing internal usage of electricity.

In the last few years the environment becomes more watchful, even for us farmers. All agricultural enterprises that exceed 200 animal units must be tested according to regulation of environment. A farm business with 200 animal units and more is classed ?environmentally hazardous activities? and has to make an environmental impact assessment for the business you have today, and the activity after expansion. Before you can construct a building and expand the numbers of animals is a lot of applications to make. I have in this project restricted me to establish a environmental impact assessment and a consultation foundation. To make a environmental impact assessment is the big part of the application. The environmental impact assessment take a lot of time and you need skills for all the rules in the environmental code to be abele to make an environmental impact assessment approved. The environment codes purposes (1 kap 1 § Miljöbalken) is to rule the laws. The purpose of the environment code is to promote sustainable development which will assure a healthy and sound environment for present and future generations. Definitions of a ?environmentally hazardous activities? 9 kap 1§ Miljöbalken) shall mean the discharges of wastewater, solid matter or gas from land, buildings or structures onto land or into water areas or ground water.

A variety of food is produced and passes the whole chain by processing, transport and trade and finally it ends up with the consumer. But in many cases, the food is disposed before it is eaten. Some of the produced food does not even pass the whole entire chain before it turns to waste. The question about food waste in debates is a case of access to food for every human beeing. It is question of consumption of the resources, waste management and an issue of environmental impact.

The RoHS Directive was introduced in order to restrict hazardous substances in Electrical and Electronic Equipment, EEE. It currently restricts the use of six hazardous substances/compounds; cadmium, lead, mercury, hexavalent chromium, PBB, and PBDE. The RoHS Directive currently includes category 1-7 and 10 in the categories of EEE listed in Annex 1A to the WEEE-Directive (Waste of EEE). The aim with the report is to investigate and elucidate prospects and obstacles to increase the scope of RoHS. This report mainly considers the inclusion of product categories 8 (Medical Devices) and 9 (Monitoring and Control Instruments).

The waste of material is a big expense for manufacture companies caused by lack of quality. The cost by lack of quality often totaled to a big percentage share of the turnover when all cost related to lack of quality is included. New manufacturing systems like Lean production or Just In Time demands better internal quality for the manufacturer. To make those manufacturing system with small and none buffer stock successful the quality improvement continuously have to be developed.Measuring of waste of material in Bubs Candy?s factory where not simple due to the products does not have a permanent weight during the manufacturing process.

Storage of biomass is often associated with problems such as heat development, dry matter losses and reduction of fuel quality. The rise in temperature can potentially cause a risk of self-ignition in the fuel storage. Moreover, emissions from storage piles can cause health problems in the surrounding. The dry matter losses and reduction of fuel quality can have economical effects. The aim of this thesis project is to develop guidelines on how to store large amount of biomass at Vattenfalls heat and power plants in an optimal way.

This master's theses was carried out on assignment from Stockholm Vatten AB as a part of a project developing new waste water treatment techniques. The goal of the theisis has been to evaluate an anaerobic membrane bioreactor for treatment of waste water from Hammarby Sjöstad. The bioreactor has not been heated and the main interest has been to study the gas production, power consumption and the reduction of organic matter and nutrients.The system has been completed with a reverse osmosis unit and a total of four batch runs have been made with good results. The use of reverse osmosis allows nutrient in the waste water to be reintroduced into circulation as the reverse osmosis concentrate can be used as crop nutrient.The membrane unit is of VSEP ("Vibratory Shear Enhanced Processing") type and an extensive membrane test has been conducted. This so called L-test helped determine the most suitable type of membrane for the system to allow a higher ±ux and thus lower power consumption.

Goods that children come in contact with on a daily basis for example toys, electronics, textiles, household items, have attracted an increased attention in recent years because of a common occurrence of residues of potentially hazardous chemical substances. Some municipalities in Stockholm have developed plans for managing chemical risks and work systematically to phase out products containing hazardous substances. This thesis aims to contribute to an improved knowledge base for any future work with non-toxic nursery schools in Haninge. The study's focus is on the challenges encountered by conditions and problems of preschool personnel to manage chemical risks in early childhood environments. Primary data was collected through a qualitative approach based on semi-structured interviews with both the preschool staff and practitioners working in the central organization of the municipality.
