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

   University dissertation from Borås : Högskolan i Borås

   Author : Pedro Souza Filho; Satinder Kaur Brar; [2018]
   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. Assessing Mineral Resource Scarcity in a Circular Economy Context

   University dissertation from Gothenburg : Chalmers tekniska högskola

   Author : Hampus André; [2020]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; supply risk; life cycle assessment; resource-efficiency; area of protection - natural resources; complex products; material flow analysis; scarce metals; circular economy; criticality assessment; electric and electronic equipment;

   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.

5. 3. Circular Business Model Design : Business Opportunities from Retaining Value of Products and Materials

   University dissertation from International Institute for Industrial Environmental Economics, Lund University

   Author : Julia L.K. Nußholz; [2020-02-11]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; 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

6. 4. Adaptive Design for Circular Business Models in the Automotive Manufacturing Industry

   University dissertation from University of Gothenburg HDK

   Author : Thomas Nyström; [2019]
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; 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

7. 5. Circular Business Models that Extend Product Value : Going Beyond Recycling to Create New Circular Business Opportunities

   University dissertation from International Institute for Industrial Environmental Economics, Lund University

   Author : Katherine Whalen; [2020-02-10]
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circular business model; product life extension; obsolescence; circular economy; business model; reuse; repair; refurbishment; sustainability strategies; sustainability education;

   Abstract : Over the past ten years, significant industry, policy, and scientific attention has been given to the ‘circular economy’, which aims to create a more sustainable society by decoupling economic growth from resource consumption. Firms are expected to play a significant role in the shift to a circular economy model by implementing circular business models that encourage prolonged use of products, components, and materials.
