2. 1. Fungi-based biorefinery model for food industry waste : progress toward a circular economy

   Author : Pedro Souza Filho; Satinder Kaur Brar; Högskolan i Borås; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; filamentous fungi; circular economy; biorefinery; food industry; fungal biomass; bioplastic; resource recovery; Resource Recovery; Resursåtervinning;

   Abstract : The food industry, one of the most important industrial sectors worldwide, generates large amounts of biodegradable waste with high organic load. In recent years, the traditional management methods to treat this waste (e.g., landfilling) have been considered not suitable because they do not exploit the potential of the waste material.

4. 2. Spatial Design for Circularity - Exploring Spatial Aspects in Housing Design with Focus on the Kitchen

   Author : Anita Ollár; Chalmers tekniska högskola; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; HUMANIORA; HUMANITIES; HUMANIORA; HUMANITIES; spatial design; value proposition; circular economy; sociomateriality; adaptability; kitchen; circular design; housing design;

   Abstract : The building industry and especially multiresidential buildings are responsible for a large portion of environmental impact, energy use and resource exploitation. Hence, there is a need to shift towards more sustainable design solutions for such buildings, which might be achieved by adopting circular economy strategies. READ MORE

5. 3. Circularity Assessment of Water and Waste in Cities : A Proposed Framework for Sustainable Performance Evaluation using LCA and LCC

   Keywords : Life cycle assessment; life cycle costing; environmental externalities cost; sustainable city; circularity; wastewater treatment; organic waste; waste to energy; assessment framework; environmental science; miljövetenskap;

   Abstract : Urbanization is a global phenomenon, happening on a massive scale and at a rapid rate, with 68% of the planet’s population predicted to be living in cities by 2050 (UN-DESA, 2018). The sustainability of a city (Goal 11 of UN SDGs) undergoing rapid urbanization depends on its ability to maintain a low consumption of resources and materials at any given time (referred to as the urban metabolic rate), whilst simultaneously providing essential municipal services to its inhabitants, such as a water supply, wastewater treatment and solid waste management.

6. 4. Landfills and glass dumpsites as future bank accounts of resources : waste characterization and trace elements extraction

   Author : Yahya Jani; William Hogland; Monica Odlare; Linnéuniversitetet; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Landfill mining; metals extraction; glass dumpsites; hazardous waste; chemical extraction; reduction-melting; Miljövetenskap; Environmental Science;

   Abstract : Environmental pollution and health threats as well as scarcity of raw materials, water, food and energy are among the main challenges our world are now facing. Simultaneously, landfills and open dumpsites still are the dominant global waste disposal option even with their long term environmental impacts in case of greenhouse gases and contaminated leachates.

7. 5. Insights to beachcast management on Gotland, Sweden : An Industrial Ecology perspective on waste-resource ambiguity

   Author : Hanna Nathaniel; Fredrik Gröndahl; Daniel Franzén; Sofia Lingegård; Johanna Spångberg; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Beachcast; natural resource management; policy; circular bio-economy; agroecosystems; governance; sustainable development; industrial ecology; Släke; naturresursteknik; policy; cirkulär bioekonomi; agroekologiska system; naturresursförvaltning; hållbar utveckling; industriell ekologi i; Industriell ekologi; Industrial Ecology;

   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
