2. 1. Turning waste into resources: Rethinking the way we discard things

   Author : Maria Isabel Ordonez; Isabel Ordonez Pizarro; Göteborgs universitet; []
   Keywords : HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Solid waste; resource recovery; material loops; waste sorting; user centred design; design with waste; waste collection systems; waste sorting;

   Abstract : Waste is one of the biggest challenges faced by our society. If not handled correctly, waste pollutes our natural environment with devastating results. However, it seems almost unavoidable that our society generates waste. READ MORE

   Abstract : Beachcast or beach wrack, washed-up algae and seaweed, used to be a highly sought-after agricultural resource (fertiliser and soil conditioner) in coastal communities around the world before being replaced by chemical fertilisers, but considering the talks of a circular bio-economy – can we reintroduce it? Since the abandonment of beachcast in agriculture, the amount of beachcast has significantly increased as an effect of eutrophication caused by the use of chemical fertiliser, and the material is commonly considered waste. Meanwhile, soils have degraded and need the multiple positive effects on agroecosystems that beachcast could provide. READ MORE

5. 3. Beyond Waste Management : Challenges to Sustainable Global Physical Resource Management

   Author : Jagdeep Singh; Björn Frostell; Olga Kordas; Anju Singh; KTH; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Sustainable global physical resource management; global waste management; systems thinking; life cycle thinking; planning framework; global environmental justice; circular economy; Industrial Ecology; Industriell ekologi;

   Abstract : Current physical resource management (PRM) was investigated in a global perspective in this thesis, to gain a deeper understanding of its implications in a sustainability perspective. In particular, the main challenges to the current PRM system and the kinds of systemic changes needed for sustainable PRM were examined. READ MORE

6. 4. A Resource-Aware Component Model for Embedded Systems

   Author : Aneta Vulgarakis; Ivica Crnkovic; Tiziana Margaria-Steffen; Mälardalens högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; component based software engineering; formal modeling; embedded systems; resources; analysis; behavior; component model; Computer science; Datavetenskap; Computer Science; Datavetenskap;

   Abstract : Embedded systems are microprocessor-based systems that cover a large range of computer systems from ultra small computer-based devices to large systems monitoring and controlling complex processes. The particular constraints that must be met by embedded systems, such as timeliness, resource-use efficiency, short time-to-market and low cost, coupled with the increasing complexity of embedded system software, demand technologies and processes that will tackle these issues.

7. 5. Small Sanitation Systems – Treatment Efficiency, Sustainability and Implementation

   Author : Brenda Vidal; Annelie Hedström; Inga Herrmann; Günther Langergraber; Luleå tekniska universitet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Sustainable sanitation; sand filter; phosphorus filter; package plant; cold climate; treatment process; system analysis; sustainability indicators; decentralization; centralization; historical development; on-site; resource recovery; source separation; source-separating systems; blackwater; urine; greywater; hållbarthetsanalys; små avlopp system; enskilda avlopp; markbädd; minireningsverk; kallt klimat; systemanalys; fosforfälla; fosforfilter; indikator; urin sortering; svartvatten; toalettvatten; gråvatten; BDT; VA-teknik; Urban Water Engineering;

   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
