Askåterföring i Jämtland : biobränslets och askans innehåll av tungmetaller relaterat till markernas geokemi

Using biofuels from regeneration cuttings is becoming more common in Sweden. Ash from the combustion of biofuels contains many valuable nutrients and base cations. The Swedish Forest Agency recommends that ash should be recycled to clearings where biofuels have been removed, to avoid future impoverishment of Swedish woodlands. In Jämtland, in northern Sweden, a large quantity of biofuels are taken out from cuttings but ash Recycling has not yet been tried. The aim of this thesis was to examine the conditions for ash Recycling in Jämtland regarding to soil chemistry and heavy metal content in soil and biofuels.

Problemidentifiering vid införandet av ett tågprojekt - En fallstudie för Stena Recycling AB

Stena Recycling AB använder sig i dagsläget av både externa lastbils- och interna tågtransporter i Norrland för att frakta material söderut. Företagets vision är att minska andelen lastbilar till förmån för tågen både av kostnads-, konkurrens- och miljöskäl. Studien har genomförts eftersom tågen nu utnyttjas till 90 procent och företaget vill använda dess maximala kapacitet. Det material som är tänkt att fraktas med det lediga tågutrymmet går i dagsläget med externa lastbilstransporter. Det är ur ett helhetsperspektiv vi vill undersöka lönsamheten samt kartlägga tänkbara problem som Stena Recycling AB står inför, när de vill överföra delar av sina vägtransporter till en intermodal lösning.

Undersökning av avfallshantering i Stockholms innerstad

According to the European Union waste hierarchy, waste should first of all be minimized. Reuse and material and energy Recycling come next. Lastly the waste should be thrown at the refuse tip. In the inner city of Stockholm waste handling can be done in various types of ways. The solutions vary as a result of the type of architecture of the building and its condition.

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.

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.

Dietary intake of zinc and iron within the female population of two farming villages in the Red River Delta, Vietnam

In many developing countries, among them Vietnam, contamination of agricultural land is a major issue that has public health implications. A fast growing population, rapid urbanization and industrialization have led to air and water emissions of potentially toxic elements (PTEs), such as cadmium (Cd). Earlier studies have shown that individuals with low iron (Fe) and zinc (Zn) status absorb larger quantities of Cd than those of adequate nutritional status. The purpose of this study was to investigate and compare the Fe and Zn intake from the foods consumed by women (15-45 years) in selected households in two agricultural villag-es in the Red River delta in Vietnam. In one of the villages the residents were involved in metal (mainly Fe) Recycling activity, whereas in the other village the residents had agricul-tural production as main source of income. Interviews, followed by food intake calcula-tions, were performed.

Statens rätt i konkurs : Lika rätt för borgenärerna?

This essay is questioning if the state as an unsecured creditor in a bankruptcy proceeding, according to the principle of equal treatment, has the same rights as the other unsecured creditors. The principle of equal treatment means that creditors with unsecured claims are supposed to have mutually equal rights to dividends in a bankruptcy. In the Swedish bankruptcy law from 1987 there are Recycling rules which means that some legal actions taken by the bankrupt debtor before the bankruptcy can be recycled to the bankruptcy estate. These rules do not apply on taxes. This essay analyzes whether the state should have this advantage or not.

Design for Recycling för hårda konsumentplastförpackningar : Betydelse under produktlivscykeln och implementering under designfasen

På grund av den globala uppvärmningen och den ökade användningen av plast de senaste årtiondena har plastavfallshantering blivit allt viktigare. Eftersom materialåtervunna produkter sparar material och naturresurser, såsom den olja som används för tillverkning av plast, är denna återvinningsmetod högst aktuell. De begränsningar som finns idag för vad som är möjligt att materialåtervinna gör det allt viktigare att anpassa förpackningar för återvinning bättre. Detta visas tydligt av att de svenska målen för återvinning av hårda plastförpackningar inte uppnås, trots dagens medvetenhet kring miljöproblemen. Denna studie undersöker därför hur Design for Recycling (DfR) kan användas och implementeras på bästa sätt för att stimulera återvinning av hårda konsumentplastförpackningar.Utifrån litterära referenser har en kartläggning av betydelsen av DfR under alla stadier i en produkts livscykel genomförts och genom denna har problemområden identifierats och pågående utveckling inom området urskilts.

En miljo?ja?mfo?relse av traditionellt stambyte kontra relining av tappvattenro?r : Med hja?lp av livscykelanalys

This study was a final thesis, for the bachelor program in civil engineering at theUniversity of Uppsala, which was made on behalf of Riksbyggen in Uppsala. Acomparative study of two stain renovation methods; tradition pipe replacement andrelining was done with an environmental perspective. A simplified life cycleassessment (LCA) was done according to the International Organization ofStandardization (ISO) with the LCA tool Eco-indicator 99, in order to be estimate theimpact on the environment. LCA is a method that follows a product or a system?from the cradle to the grave?, which means that all the environmental impact over alifetime is considered.The work was executed by using a stairway with nine apartments in a house called?Uppsala Hus 9? as a reference object, which was provided by Riksbyggen.

Krav på exportlicens vid gränsöverskridande transporter av farligt avfall inom EU

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.

PLASTHANTERINGEN I SVERIGE En kvalitativ studie om storstadskommunernas plasthantering utifr?n EU:s Plastdirektiv (EU) 2019/904

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.

Källsortering och återvinning : upplevda problem, orsaker och tänkbara lösningar

We are soldiers, not policemen.Denna uppsats rör det vakuum som ofta uppstår när en regim faller samman på grund av krig, och dess ordningsmakt upplöses, eller av annat skäl inte förmår upprätta ordningen. Ofta inträffar plundring och upplopp i det ?polisiära? tomrum som inträffar från det att den tidigare regimens ordningsmakt drar sig undan, till dess att en ny poliskår träder in och bör-jar återupprätta lag och ordning. Av olika skäl frånsäger sig den intervenerande makten inte sällan arbetsuppgifter av mer ?polisiär? natur, alltifrån att bevaka samhällsviktiga byggnader till att dirigera trafik.I stor utsträckning följde kriget i Irak våren 2003 detta mönster från tidigare konflikter; ordningsmakten drog sig undan, plundring utbröt och koalitionen, bestående främst av USA och Storbritannien, nekade inledningsvis till att det var deras uppgift att ingripa mot laglösheten.
