1. 1. Carbon materials: towards a circular economy through thermochemical recycling of mixed waste

   Författare :Isabel Cañete Vela; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; plastic waste; circular economy; thermochemical recycling; mixed waste; recycling; Carbon materials; steam cracking;

   Sammanfattning : Carbon-containing materials, such as paper, wood, plastic, and textiles, are essential for our daily lives, being used in everything from clothing to infrastructure. However, their use typically follows a linear pattern, in that we extract carbon resources, create products, and eventually dispose of them, thereby contributing to greenhouse gas (GHG) emissions throughout the supply chain.

3. 2. Carbon materials: towards a circular economy through thermochemical recycling of mixed waste

   Författare :Isabel Cañete Vela; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; circular economy; recycling; mixed waste; thermochemical; carbon materials;

   Sammanfattning : Carbon materials, such as paper, wood, plastic and textiles, play an important role in our everyday life, from clothes and packaging to infrastructure. However, the use of those materials follows a linear way. We take carbon resources, we make products, and we discharge them in a short amount of time, producing GHG emissions along its supply chain.

4. 3. Recycling Potential and Design for Disassembly in Buildings

   Författare :Catarina Thormark; Institutionen för byggvetenskaper; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Arkitektur; interior design; Architecture; LCA; Environmental Assessment; Deconstruction; Disassembly; Design; Building Products; Recycling Potential; Recycling; Building Waste; inredningsarkitektur; Building construction; Byggnadsteknik; Environmental technology; pollution control; Miljöteknik; kontroll av utsläpp;

   Sammanfattning : Recycling as part of environmental considerations has become a common feature in architecture and building construction. Recycling of building waste can make a considerable contribution to reducing the total environmental impact of the building sector. LÄS MER

5. 4. Policy Framework for Material Resource Efficiency : Pathway Towards a Circular Economy

   Författare :Leonidas Milios; Internationella miljöinstitutet; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; resource efficiency; circular economy; policy studies; reuse; remanufacturing; recycling;

   Sammanfattning : The strategic direction of the European Union (EU) over the past twenty years has focused on increasing resource productivity and innovation in the economy, aiming at the efficient use and secured supplies of resources, economic growth and job creation, with fewer environmental impacts. One of the basic premises of the new ‘Green Deal’ for Europe is the promotion of the circular economy. LÄS MER

7. 5. The Technology and Economy of Farm-Scale, High-Solids Anaerobic Digestion of Plant Biomass

   Författare :Mattias Svensson; Bioteknik; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; farm-scale; Bioteknik; farmhouse construction; Lantbruksteknik; Biotechnology; agricultural machines; kontroll av utsläpp; Agricultural engineering; Miljöteknik; pollution control; Environmental technology; Lantbruksekonomi; straw bed priming; stratified bed digesters; nitrogen recycling; greenhouse gases; Sweden; Agricultural economics; sequential single-stage fed-batch; ley crops; sustainability; wheat straw; sugar beet tops; crop residues; high-solids; economy; Anaerobic digestion; biogas upgrading;

   Sammanfattning : Anaerobic digestion is a microbially mediated process occurring in nature in the absence of oxygen and other non-carbonaceous electron acceptors. The majority of the carbon of the organic matter degraded in the process is transformed into carbon dioxide and methane. LÄS MER
