  2. 1. Designing out waste - Exploring barriers for material recirculation

    Author : Isabel Ordonez Pizarro; Chalmers tekniska högskola; []
    Keywords : HUMANIORA; HUMANITIES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste sorting; sustainable development; Water; Waste; Urban; waste management; Resources; resource recovery; ​Recycling; designing with waste; recycling;

    Abstract : This doctoral thesis has investigated what hinders material recirculation in society, to later suggest possible ways to support material recirculation in the future. Since material recirculation is proposed as a way to use waste materials for new production, it was deemed relevant to investigate two separate case studies that enabled recirculation from production systems and waste management.

  4. 2. Logistics Systems for Recycling - Efficient Collection of Household Waste

    Author : Marianne Jahre; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; waste col lection systems; reverse distribution; green logistics; collection; reverse logistics; recycling; environment; waste;

    Abstract : This dissertation investigates collection and recycling of household waste with focus on packaging materials. The purpose is how to describe and explain the d esign of a collection system according to different system environments in orde r to achieve high logistics performance in terms of low cost and high service.

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

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

    Abstract : 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.

  6. 4. Systems Aspects of Increased Swedish Waste Incineration

    Author : Jenny Sahlin; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; biological treatment; incineration tax; waste management; waste import; value of households’ time.; waste incineration; district heating; MSW; landfilling ban; recycling;

    Abstract : Abstract Recent bans on landfilling of combustible and organic waste in Sweden have resulted in an increase in alternative waste treatment, especially waste incineration with energy recovery. This thesis elucidates how the current increase in Swedish waste incineration affects and is affected by the two systems to which it belongs: the waste management and the energy systems. READ MORE

  7. 5. Recycling of TiO2 Pigments from Waste Paint: Process Development, Surface Analysis, and Characterization

    Author : Mikael Karlsson; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Recovery; Paint; Titanium dioxide; Waste.; Municipal solid waste handling; Pyrolysis; Pigment;

    Abstract : Pigments are commonly used in paint, plastic and paper products and titanium dioxide (TiO2), the most important white pigment, accounts for approximately 70 % of the total volume of all pigments used today. Minerals containing TiO2 are relatively abundant in the earth’s crust. READ MORE
