1. Halvvägs mellan dåtid och framtid : ett anslutande gestaltningsförslag för Gjuteriparken
University essay from SLU/Dept. of Landscape Architecture, Planning and Management (from 130101)Abstract : Det här arbetet tar avstamp i Malmö kommuns planer att utveckla Gjuteriparken, ett avlagt järnvägsfragment i norra Limhamn. Förfallet av tidigare järnvägsverksamhet gav upphov till platsen som den är idag: när växter etablerat sig på den gamla banvallen och ny, spontan användning uppkom i hålrummet som uppstått efter tågen slutat gå.

2. Idealised remediation scenario in two small-scale intersecting fractures
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Analysis of mass transport in rock fractures has become increasingly important in underground storage of radioactive materials and remediation of polluted groundwater in fractured rock aquifers. Permeability of rock mass is regulated by present rock fractures, where flow is mainly through the fracture networks. READ MORE

3. Modelling of Fluid Flow and Contaminant Transport in Fractured Rock : Case Study
University essay from KTH/Hållbar utveckling, miljövetenskap och teknikAbstract : Drinking water contamination is a big concern in Sweden and is commonly traced back to being waste from former manufacturing industrial sites. Pollutants in the topsoil can be remediated by several techniques, such as decontamination or excavation but the toxins already enclosed in the bedrock cannot be treated the same and is harder to track possible contaminant pathways.

4. Critical elements scavenged by secondary gypsum and HFO : Determined by sequential extraction combined with mineralogical studies
University essay from Luleå tekniska universitet/Geovetenskap och miljöteknikAbstract : The demand for metals is great for the purpose of developing green technologies, and EU has listed 30 metals and minerals that are of critical importance for the maintenance and evolving of today’s society, so called critical materials. However, mining of raw materials generates mine waste which can have adverse effect on human health, ecosystems, and surrounding areas. READ MORE

5. Long-term Effect of Metallic Iron Sorbents on Arsenic Mobility in an Anoxic Aquifer : An assessment based on long-term column experiments
University essay from SLU/Dept. of Soil and EnvironmentAbstract : Zero valent iron (ZVI) sorbents have successfully remediated soils burdened with different groups of contaminants. When working to alleviate arsenic (As) contamination, the location-specific subsurface chemistry greatly affects the efficiency of the sorbents as it controls the speciation of As and the transformation of the ZVI, as well as the interaction between these (remediating mechanisms).
