Kjell : Ett examensarbete som syftar till att underlätta källsorteringen i svenska privathem

Abstract (in English)During the last fifty years, the waste in an average Swedish household has increased by about five hundred percent. In order to manage (eller take care of) all of this new waste, Swedes need a method of facilitating the handling process. In this report, both the habits and needs among private households across Sweden are investigated, followed by a pertinent solution to the waste problem. This solution is a container with two compartments, using the standarddimensions of a grocery store paper bag..

Inventering och karakterisering av brännbart avfall i
Norrköpingsregionen

The purpose of this study has been to make an inventory of combustible waste in the region around Norrköping and to investigate the composition of domestic waste, industrial waste and two different types of sludge. The work was performed at the request of Norrköping Miljö & Energi, due to the planning of an incineration plant. The inventory of the waste was performed through inspection of environmental impact reports, from waste disposal plants in a number of local government areas in the region. The quantities were also compared to another inventory, carried out in a different way. The characterisation of the wastes was compared to the fuel specification determined by Norrköping Miljö & Energi.

Environmental impact assessment of energy recovery from food waste in Singapore : comparing biogas production to incineration

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.

Garbage to gardens : design proposals for two decentralised waste management units in Pune, India

The population growth and urbanisation in low-income countries bring issues of poor living standards and miserable sanitation conditions onto the agenda. If well-functioning Waste Management systems were developed, this could master some of the problems. The already existing local informal waste handling system that is common in many low-income countries, needs to be developed with proper sorting and composting solutions to decrease the environmental burden and improve the overall situation in the dense cities. This master?s thesis project is performed with the intention of developing functional decentralised Waste Management units in the city of Pune, India.

Avfallsdirektivets påverkan på efterbehandling av förorenad mark

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.

Utredning om en ökad biologisk behandling av matavfall i Halmstads kommun

Environment and sustainable development are very current topics in today's society, bothnational and international. The government's bill 2004/05:150 ?Swedish environment objectives - a common commission? contains several environmental quality objectives, that in turn is divided up in smaller secondary objectives. One of the secondary objectives says: ?Latest year 2010 shall at least 35% of the food waste from households, restaurants, largescale kitchens and shops be recycled through biological treatment.

Vinster med återvinning, Stena Recycling

This project operate an environmental assessment of total waste was conducted by using a life cycle assessment (LCA), that examines the environmental benefits of recycling production waste from Atlas Copco at Stena recycling. Atlas Copco is a company engaged in the development and production of rig-mounted hydraulic breakers and handheld air breakers and handheld motorized rotisserie. Stena recycling is a recycling company engaged in recycling, processing and refining of metals, paper, electronics waste and hazardous waste.The purpose of this study is to focus on Stena customer Atlas Copco and evaluate environmental benefits between to recycle and not to do it. The result shows that the total energy gain, resulting from the recycling of waste fractions, lands at 6 990 089 MJ, corresponding to drive 3 times around the Equator with a truck (40 t). The result shows that recycling 3040 kg paper provides an energy gain of (38 600 MJ) compared with burning paper (19 500 MJ) is 19 100 MJ, which corresponds to heat a house for 11 weeks.

Undersökning av miljöstatusen i Gothemsån / Dalhem i anslutning till utsläpp av lakvatten från sopdeponi i Roma 2010

In October 2010 it was discovered that leach water had been released from a waste deposit directly into a ditch during a period from March until October 2010. The river Dalhemsån runs close to the waste deposit, just about 10 meters from the ditch. By studying the benthic fauna it was discovered that the environmental status of Dalhemsån is bad in this part of the river, but the discharges of leachate from the waste deposit does not seem to have deteriorated the water further since May 2010..

Återvinning av dryckeskartonger : En studie som syftar till att öka återvinningsgraden av Tetra Paks förpackningar i Indonesien

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.

Miljöoptimera avfallsindustrin i Sverige : - återvinn restprodukten gips

One of the most common ways to produce heat and electricity in Europe today is by the incineration of waste or combustion of coal. These materials can be very sulfurous and during combustion sulfur dioxide is produced. This is an environmental and health related toxic substance which is why power plants have strict regulations on removing it from the flue gas. Sulfur dioxide is removed from the flue gas by adding a limestone reagent. The sulfur dioxide reacts with the limestone and the synthetic product obtained is ?Flue Gas Desulfurization gypsum?.

Spillvärmeåtervinning ur kylvattensystemet ismältverket på Sapa Profiler AB i Sjunnen

The smelting process at Sapa Profiler AB in Sjunnen generates large quantities of waste heat which is absorbed by the cooling water when the aluminum is cooled down. This paper is the result of a Master?s Degree Project aiming to present the conditions for recycling the waste heat. The cooling water absorbs the heat from the aluminum at an average rate of 600 kW and the paper shows that it can be used to replace electrical power consumption for heating the production plant?s facilities.
