  2. 1. 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

  4. 2. Investigation of Ilmenite from Oxygen Carrier Aided Combustion: Sulfur Interactions and Recovery of Elements

    Author : Mariane Vigoureux; Chalmers tekniska högskola; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Recycling; Oxygen Carrier Aided Combustion; Circulating-Fluidized Bed; Ash; Sulfate process; Sulfur; Biomass; Ilmenite; Leaching;

    Abstract : Oxygen- Carrier- Aided Combustion (OCAC) is a promising technology for the combustion of solid heterogeneous fuels such as biomass and waste in fluidized-bed (FB) units. In OCAC the conventional bed material silica sand is replaced by an oxygen carrier (OC). Replacing the bed material with an OC has many advantages. READ MORE

  6. 4. Logistics systems for recycling : on the influence of products, structures, relationships and power

    Author : Maria Huge Brodin; Linköpings universitet; []
    Keywords : logistics systems; recycling; products structures; relationships; power; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP;

    Abstract : The environmental trend, and environmental legislation, has during the past decade grown stronger, and with it the focus on environmental issues within many fields of research and practice. This has implications for logistics, and the focus in this dissertation is on the logistics systems that are needed to realise recycling of end-of-life products: logistics systems for recycling (LSRs).

    Abstract : In the modern practice, a sustainable development strategy in a domain of wasteutilization is shifting its focus from a general completeness of recycling to a morespecific attention to efficiently utilize elements in the wastes. This is well-illustrated bythe steelmaking slag industries. READ MORE
