2. 1. Circular Manufacturing Systems : A development framework with analysis methods and tools for implementation

   Author : Farazee M A Asif; Amir Rashid; Peter Hopkinson; KTH; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Circular economy; circular manufacturing systems; resource conservative manufacturing; ResCoM; system dynamics; Production Engineering; Industriell produktion;

   Abstract : The society today lives on the philosophy of ‘take-make-use-dispose.’ In the long run, this is not sustainable as the natural resources and the waste carrying capacity of the earth are limited. Therefore, it is essential to reduce dependency on the natural resources by decoupling the growth from the consumption. READ MORE

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

   Author : Pedro Souza Filho; Satinder Kaur Brar; Högskolan i Borås; []
   Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; 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.

5. 3. Assessing Mineral Resource Scarcity in a Circular Economy Context

   Author : Hampus André; Chalmers University of Technology; []
   Keywords : NATURVETENSKAP; NATURVETENSKAP; TEKNIK OCH TEKNOLOGIER; NATURAL SCIENCES; NATURAL SCIENCES; ENGINEERING AND TECHNOLOGY; supply risk; criticality assessment; scarce metals; electric and electronic equipment; circular economy; complex products; resource-efficiency; area of protection - natural resources; life cycle assessment; material flow analysis;

   Abstract : Due to humanity’s dependence on metal resources there are growing concerns regarding impacts related to their potential scarcity, both for current and future generations. The vision of a more circular economy suggests that extending the functional use of metals through measures aiming for resource-efficiency (RE) such as increasing technical lifetime, repairing and recycling could reduce mineral resource scarcity.

6. 4. Circular Business Model Design : Business Opportunities from Retaining Value of Products and Materials

   Author : Julia L.K. Nußholz; Internationella miljöinstitutet; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; TEKNIK OCH TEKNOLOGIER; SAMHÄLLSVETENSKAP; ENGINEERING AND TECHNOLOGY; SOCIAL SCIENCES; Circular Economy; business model innovation; circular business model; Resource efficiency; Reuse; Life cycle management; Value creation; sustainability assessment; Circular business model tools;

   Abstract : Today our economy is largely based on linear material flows, and many products, such as electronics, furniture,building materials and textiles, are discarded even when they could still be used. Without urgent action, globalwaste is expected to increase by 70% by 2060 and global materials use is expected to more than double. READ MORE

7. 5. Adaptive Design for Circular Business Models in the Automotive Manufacturing Industry

   Author : Thomas Nyström; RISE; []
   Keywords : Circular Business Models; Product Service System; Business and Design Logic; Circular Economy; Design for Circular Business Models;

   Abstract : The vision of a circular economy (CE) promises both profitability and eco-sustainability to industries, and can, from a material and energy resource flow perspective, be operationalized by combining three business and design strategies: closing loops; narrowing and slowing down resource flows by material recycling, improving resource efficiency; and by extending product life by reuse, upgrades and remanufacturing. These three strategies are straightforward ways for industries to radically reduce their use of virgin resources. READ MORE
