1. On-site sanitation systems - An integrated assessment of treatment efficiency and sustainability
Abstract : Small on-site sanitation systems for wastewater collection and treatment are prevalent in suburban and rural areas in many countries. However, these systems often underperform, causing potential impact to the receiving waters and increasing the risks to public health, thus hindering the overall sustainability of the systems.

2. Processing Aspects for Improving Mechanical Properties in Aluminium Castings
Abstract : The relation between the process and mechanical properties in aluminium alloys for castings has been examined. The relation was hard to define since the spread in data was severe due to defects created in the casting process. To avoid such defects a gradient solidification equipment was built. READ MORE

3. Small Sanitation Systems – Treatment Efficiency, Sustainability and Implementation
Abstract : Current socio-technical wastewater system paradigms are being challenged by emerging global issues such as climate change, environmental degradation and scarcity of resources. Thus, exploration of innovative new urban water management solutions is required that enable closure of resource loops. READ MORE

4. Towards Energy-Efficient Drinking Water Production using Biomimicry
Abstract : Water is a prerequisite for life and we therefore need pure drinking water to survive. Yet there are more than half a billion people that do not have access to pure drinking water. Water treatment can be performed in many different ways, one of the most commonly used being filtration. READ MORE

5. Microplastic Mitigation in Urban Stormwater : Assessing Horizontal-Flow Filters of Bark, Biochar and Sand as Remediation Strategies
Abstract : Urban stormwater has been suggested as a significant vector through which microplastics (MPs) reach aquatic environments. Currently, only a small fraction of stormwater in Sweden undergoes any form of treatment. READ MORE
