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 Recovery in A Dual Fluidized Bed Gasifier

   Författare :Sébastien Pissot; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; recycling; dual fluidized bed; chemical looping gasification; circular economy; carbon recovery; biomass; plastic waste;

   Sammanfattning : As the concept of a circular economy gains acceptance and awareness of climate change and its disastrous consequences increases, the ways in which we produce the carbon-based goods upon which so much of our economy depends need to change. Society must end its reliance on fossil carbon resources and shift to renewable sources that enable the establishment of a carbon cycle. LÄS MER

4. 3. Fruit wastes to biomaterials : Development of biofilms and 3D objects in a circular economy system

   Författare :Veronika Bátori; Kristiina Oksman; Högskolan i Borås; []
   Nyckelord :apple pomace; biodegradable; bioplastics; circular economy; orange waste; resource recovery; Resource Recovery; Resursåtervinning;

   Sammanfattning : To address the current plastic pollution problem, the replacement of conventional plastics with bioplastics can be considered. Although the land use of crop cultivation for bioplastics is still negligible, there is an increasing interest in the utilisation of lignocellulosic waste products for the production of bioplastics.

5. 4. 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.

7. 5. Strategies for Complete Recovery of Carbon in Dual Fluidized Bed Gasifiers

   Författare :Sébastien Pissot; Chalmers tekniska högskola; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; waste; dual fluidized bed; chemical-looping; carbon; circular economy;

   Sammanfattning : To establish a circular economy and curtail our dependency on fossil resources, technologies are needed to extract carbon from biomass and plastic waste. Dual fluidized bed (DFB) gasification is a carbon-extracting technology that offers flexibility in terms of its inputs, outputs, design, and operational conditions. LÄS MER
