Förorenade områden är ett problem då föroreningarna kan påverka hälsa och miljö. När förorenade områden saneras genom schaktning eller muddring utgör schaktmas-sorna ett avfall. Avfallsklassificering är en viktig del vid sanering av förorenade områ-den. Det finns mycket lagstiftning att förhålla sig till och många analysmetoder att välja på. Detta kandidatarbete syftar till att avfallklassificera och identifiera aktuell de-poni för bottensedimenten i Vinterviken i södra Stockholm samt diskutera resultatens relevans mot bakgrund av forskning på området. Resultaten visar att bottensedimen-ten utgör ett icke farligt avfall som på grund av sin TOC halt inte kan placeras på de-poni utan att genomgå förbehandling eller att dispens från gränsvärdena ges. Det finns osäkerhet i de reglerade analysmetoderna och redovisade avfallsegenskaper kan på denna grund ifrågasättas.

This project deals with a transformation of a park to an entity of a urban scale. Context; Stockholm is growing but have many spaces that could connect areas but doesn’t. They often connect with small gestures but have big spaces of nothing which is experienced as unsafe and uninviting borders. I would like to propose a change for one of those areas. Minor architecture; I would like to do minor insertions in this park to unify and clarify it. To do this I propose a concrete path that spans the full lenght of the park and with some structures along the way to activate the parts that lacks it today. The main idea of the path is to establish something constant and durable so that it gives upportunity for the activities and functions to evolve around it without dissolving the base structure of the park.

Stockholm is an archipelago of islands connected by water that historically has been an important resource for the city and for the industries, which found an easy access for ships and therefore they settled on strategic positions along the edges. This thesis investigates the topics of water, industrial heritage and edges in the city of Stockholm: these aspects are strong in their individual identity but they also interact in a powerful and interesting way. This work intervenes where this pattern is still visible -due to the presence of water and industries- but not accessible because it lacks the third element of connection with the city. The aim is therefore to investigate strategies that increase and reconnect the potential of these aspects that got disconnected through time. To obtain accessibility and usability, the edge was transformed and redefined to enhance the experience of walking along it. An analysis was carried out and a proposal was designed for the site of Lövholmen, which has these characteristics -the water, a strong industrial heritage and proximity to the city- that are now disconnected. The opening of the edge and possibilities of walking will transform and reconnect the site - and the richness in it- with the city of Stockholm.
