Organic material used for biogas production can also undergo other treatments. The emissions and impact from the different treatments are evaluated in this environmental assessment, with a focus on energy and climate. The materials included in the study are organic household Waste, slaughterhouse Waste and liquid manure. Other than biogas production, the possible treatments for organic household Waste and slaughterhouse Waste are incineration and composting, and for liquid manure storing and spreading. The analysis is based on data and information from current and relevant literature, and relates to the conditions in the Swedish energy system.

The purpose of this analysis was by qualitative semi-structured interviews with twelve children 5-years old and six pre-school teachers at three pre-schools, a total of six departments, find out how pre-school teachers worked with Waste separation, if it motivated the children to take care of the environment, and if the work was understandable for the children. The results showed that the children did not comprehend what the pre-school teachers expressed that they worked with regarding Waste separation and actions connected to caring for the environment. The pre-school teachers also expressed that the children was not mature enough to learn about the process when Waste separated garbage is recycled, and that the work with the subject therefore had been carried out on a lower level. The children however expressed knowledge that did not come straight from their actual every day life, but since dialogue about the subject did not seem to exist between pre-school teachers and children, the pre-school teachers appeared to have failed in making the learning meaningful and understandable for the children, from their knowledge, experiences and interests..

The production costs have steadily increased within the construction industry during the 21st century. Voices are raised meaning that the construction industry is too unsuccessful in making the production more efficient and to develop it?s way of working. One way to deal with the production costs is to minimise the Waste, with Waste meaning activities that doesn?t add value to the finished product.

Today's society is facing major challenges. In order to reduce the climate impact fossil fuels should be replaced with fuels that do not contribute to the greenhouse effect. The growing population generates organic Waste originating from industry and households so called organic fraction of municipal solid Waste (OFMSW). Through anaerobic digestion, Waste can be utilized to produce energy-rich methane gas. In this way, Waste can be a resource instead of a burden on society.

Käppala Wastewater treatment plant situated on the island of Lidingö northeast of Stockholm is running a project during 2004 and 2005 with the purpose to map out the capacity of anaerobic digestion in the digesters that treat primary and excess sludge. The purpose of this thesis work, which is part of that project, was to characterize the present anaerobic digestion process and to investigate its capacity to treat other organic Wastes such as restaurant Waste and Waste from water works. To decide the potential of both methane and biogas production from different substrates batch laboratory tests were carried out. To imitate the anaerobic digestion process at Käppala continuous tests with small scale reactors were carried out. These reactors were later fed with restaurant Waste.The batch laboratory tests showed that primary sludge had a potential biogas and methane production of 0,62 and 0,35 Ndm3/g VS respectively after 40 days of digestion.

The main project Dry preservation of food Waste from households includes a new technique concerning drying and storage of dried bioWaste as well as a study of the sorting of household Waste and further usage of the dried bioWaste. A question asked in the project is, can the dried bioWaste be used as a soil amendment? If organic Waste is used as a soil amendment, precaution concerning hygienic safety risks has to be accounted for. The objective of this M. Sc.

This report, written by Ma?ns Ridze?n and Jonas Stenberg, presents the thesis carried out the spring of 2012. The authors met the first time in 2008, when they started their studies at Uppsala University. Since then they have completed various projects, both within and without the university. This study is based on a theory that was first conceived when Jonas Stenberg did his internship in the summer of 2010.

The purpose of this essay is to draw attention to the obstacles that affects the internal trade of Waste within the EU. The essay doesn?t in any way encourage pollution or illegal handling of Waste but unfortunately there are large profits to be made from illegal destruction and recycling of Waste and especially hazardous Wastes. Therefore the dependable companies handling Waste must access a market with fast and flexible (but predictable) regulations as well as lower transaction costs to help make the environment better and encourage a strive for increased recycling. There are examples where some Waste only can be sent to a land-fill within the country but could be recycled in other EU-countries.

The evaluation of the function of the feeding of sheep herds is suggested to involve the work effort, the fulfilment of the nutrient needs of the sheep and the feed Waste. Mechanisation of the feeding can be very simple or include high degrees of mechanisation. Three different farms, representing different levels of mechanisation are presented. Descriptions and analysis of the feeding systems including mechanisation, work effort and estimations of the feed Waste are made on each farm. The herd with the most advanced feed mechanisation included a rolling feed band and mix wagon. The other farms were partly or little mechanised including ad lib feeding from big bales and manual distribution of hay and concentrates. The most mechanised farm was able to feed a large herd of sheep at a low work effort and little feed Waste. However, the investment in machinery has to be weighed against the improved efficiency.

According to recent statistics the construction industry is responsible for the largest Waste discharges of both dangerous and non-dangerous Waste, when disregarding the "non-dangerous" amount of granite Waste produced by the mining industry and the Waste produced by the pulp and paper industry. Preventive work within Waste management is an ongoing practice so to be able to reduce negative environmental effects. One of the most common actions for the companies to take is to separate the different kinds of Waste from one another at the construction site. Although by working with the problem in earlier stages of the process a large amount of the Waste could already have been reduced.Companies in the construction business that are actively working to decrease environmental impact in their operations often use an EMS (Environmental Management System). By using environmental management as method the company can manage their environmental work so that actions can be taken where they are needed the most.

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.
