Verktyg för lönsamhetsberäkningar vid bränslekonvertering av spetslastpannor från olja till pellets

This report summarizes the development of a calculation program estimating the profitability of converting a peak-load oil-fired boiler to pellets. To convert an oil-fired boiler to pellets a new fuel handling system must be designed. Changes also have to be made to some other components. Since there are many different techniques for transportation, storage and treatment of the fuel only the most interesting techniques from Swecos experience and interest were included in the study.The capacity of the different parts in the system was dimensioned based on the power of the boiler after conversion. To estimate prices, installed power and dimensions manufacturers and distributers were contacted.

Kundfokuserad miljökommunikation med CRM-system : En Fallstudie hos Green Cargo

BackgroundToday a common approach to solve a complicated problem is to assemble a temporary workforce in order to solve the problem by working together within a project. One of the difficulties with working in projects is to maintain the planned budget. Working hours and costs are often exceeded. Many companies presume that any certain project will succeed, a presumption that leads companies not to anticipate risks involved in a project. In companies today there is seldom time for evaluation or moderation of a project, in order to have time for evaluation there is a great need for an adequate planning of the project.IntentThe intention with this study is to create a model for planning, budgeting and evaluation of projects within consultancy companies.MethodWith the help of interviews and discussions within the group Hamnar och Byggkonstruktioner at Sweco has evidence to present a proposal on planning, budgeting and monitoring been developed.ResultsA model has been developed to ease for consultancy companies to plan, budget, monitor and evaluate projects.

Ekologisk dagvattenhantering på parkeringsytor : Lösningsförslag för Eurostop köpcentrum i Halmstad

Stormwater from trafficked areas often contains high pollution levels. In traditional stormwater management design, stormwater is first transported away through piped networks, and then in most cases passes through oil separators before finally reaching the recipients. While this traditional method removes certain pollutants from the stormwater, it does not reduce the total flow, as in the case of ecological stormwater management. In the ecological method the stormwater is not simply transported away, but is recirculated through infiltration, percolation, and detention. The aim of this study is to investigate possible advantages of ecological management designs, in contrast to traditional management.

Identifiering av slöserier på Lundbergs Plåt AB

Lundbergs Plåt AB is a small company situated in Jönköping. Their main task is to process different kinds of steel such as stainless steel. Lately, they have shown an interest in Lean production.On the basis of the situation mentioned above, we developed the purpose to find and decrease the non value-added wastes in the production at Lundbergs Plåt AB. Out of this, we also developed and answered two questions: Which wastes can be found with help from a value stream mapping (VSM)? In what way can these wastes be reduced and how can these reductions contribute to an improved production? VSM is the method used to find the non value-added wastes.

Ökad återvinning i modebranschen : försörjningskedjans hinder och möjligheter inom produktutveckling

En ökad textilkonsumtion har lett fram till en problematik kring miljöpåverkan på grund av den ökade mängden använda textilier som ska hanteras efter produkternas död. För att ta till vara på de dyrbara resurser som har använts för att skapa textila produkter, har intresset för återvinning av textila fibrer ökat. Forskningen inom återvinning av bomullsfibrer har däremot inte kommit tillräckligt långt för att produktion av återvunna fibrer av hög kvalité ska kunna göras storskalig. Detta speciellt eftersom problem med exempelvis blandfibrer och separerbarhet försvårar arbetet. Det finns förändringar som kan göras av modeföretag i produktutvecklingsfasen redan idag, vilka kan underlätta återvinningsprocessen och syftar till att skapa ett slutet system i framtiden.

En man och hans ?pplen: en fallstudie av Carl Str?mbergs ?ppeltr?dg?rd

This bachelor?s thesis studies Carl Str?mbergs ?ppeltr?dg?rd, a private garden consisting of a large number of apple trees and varieties. The garden is located outside ?rebro, in N?rke, and is owned by a unit owner association whose goal is to preserve and determine the varieties. Through interviews, articles, site visits and documents from Carl Str?mberg, the purpose have been to get an understanding of who Carl Str?mberg was, how he collected the apple varieties and how that process was affected by the climate amongst apple growing and pomology during that time.

Samspelseffekter vid kapacitetsförbättringar. : Exempel från Dalabanan.

The trend in the transport sector is moving towards eco-friendly, fast and convenient transportation,this results in higher demands on railway transports. To meet the demand and quality requirements,the Swedish railway network will have to expand. The cheapest way is to expand little by little butwhat impact do these small steps actually have on the capacity?This thesis examines the interactions of different improvement for the capacity on a single-trackrailway. Through simulations in the software tool RailSys this report studies what effect block signals,extra meeting stations and rebuilding existing two track passing loops to three track loops have onthe capacity.

Sverige ut ur EU : ett dilemma för vänster- och miljöpartiet?

This paper addresses how political parties make decisions. Parties often have to choose between conflicting objectives such as influence on policy, control of the government, and support among the voters. This paper examines the behavior of the two Swedish parties on one of their particular policy positions: Swedish withdrawal from the EU. The aim is to describe why the Left Party (Vänsterpartiet) and the Green Party (Miljöpartiet) retain thisspecific policy position when it on one hand seems damaging to their chances of getting into government, and on the other seems to be an unrealistic policy to realize. I undertake a twocase study of the two Swedish parties, which I assume to represent a population of Nordic parties critical to the EU.

SCA Skogs arbetsmetoder för att fastställa nyttan av en väginvestering

The basis of road investments is to minimize the transportation cost. The forest industry wants roundwood to be available during the whole year. One way of determine which road to invest in is to do a cost/benefit calculation. SCA Forest lacks a uniform approach to determine the utility of a road investment. The goal of this report is to describe how the organization works today and find areas of improvement. The data collection was done through interviews.

Transportkvalitetshöjande åtgärder : en fallstudie vid GP-Last

This thesis has been done on a haulage contractor company named GP-Last (AB Gustav Perssons Åkeri) and the purpose with the paper was to analyse their traffic from Malmö to Stockholm and leave suggestions on efforts that GP-Last can use to increase their level of transportation quality. This has been done with two main questions, which problem do they have today and which efforts they need to do to solve their problems? Through a case study with interviews as method to collect data it showed that GP-Last had four main problems.        Not enough information about their freights. The transport planning unit in Malmö doesn?t have the exact delivery address when GP-Last begins to bring in the gods.        There are no clear routes.

Finns det potential att införa en massdatabas för handel och utbyte av överskottsmassor i Eskilstuna?

In Eskilstuna and Sweden in general the level of reuse of surplus material containing soils and rocks from excavation is low. In this report the potential for increasing the reuse of excavated material in Eskilstuna by using a web-based earth information database has been examined. The purpose of a web-based earth information database is to connect those who have surplus material with those who need material for a fast and simple transaction. The intention is to give Eskilstuna a more environmentally and economically efficient handling of surplus material by increasing the level of reuse and thereby reducing the amount of surplus material that is wasted and emissions given off to the atmosphere during transportation. The potential has been examined in two different ways, by tracing information about a number of projects to see if excavated material driven to the dump could have been used in another project and by interviewing eight of the work leaders active in Eskilstuna.

Skogsåkeriägares inställning till organisationsförändringar :

There are two groups of haulage contractors in roundwood transport , those who are contracted direct by the transport buyer and those who are connected to a freight company which in its turn is contracted by the transport buyer. Today the roundwood haulage is dominated by contractors with one to two lorries. The effort of coordinating transportation for a transport buyer is dependent on how many communication contacts that must be managed (how many individual haulage contractors the transport buyer has to work with). A structural change in the sector that leads to a decrease in the number of haulage contractors but an increase in the capacity of each contractor, makes it possible for a transport buyer to coordinate transports with fewer communication contacts. The reason why a company reaches a certain size can be explained by the number of contracts it makes and manages.

Miljöarbete på bibliotek: En komparativ studie av tre folkbiblioteks yttre miljöarbete

A trend since the early 90?s has been that some public libraries offer a special shelf containing environmental information to the community, but it seems as though the subject has been overlooked by the literature and the science community. The purpose of this bachelor thesis is to study how three independent public libraries work with environmental information that is made available to the community. The following questions were addressed: 1) Which arguments can be found as to why the libraries offer this activity? 2) How does the environmental work at the public libraries look and what does it contain of? 3) Are there any similarities or differences in this work between the three libraries?To answer these questions interviews with librarians were carried out; observations were made to complement the interviews.
