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

    Författare :Mikael Karlsson; Chalmers tekniska högskola; []
    Nyckelord :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;

    Sammanfattning : 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. LÄS MER

  3. 2. Recovery and reuse of TiO2 and other pigments from paint waste

    Författare :Mikael Karlsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Titanium dioxide; Paint Waste; Recovery; Pyrolysis;

    Sammanfattning : Titanium dioxide (TiO2) has numerous applications in our society, most notably as a white pigment in products such as paint, paper and plastic. Since 2010 there has been a sharp increase in the demand for and price of TiO2. As a result new and innovative ways of TiO2 production are needed. LÄS MER

  4. 3. Chemical risk information in product chains: The cases of paint and textile

    Författare :Kristin Fransson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; supply chains; paint; textile; Chemical risk information; product chains; REACH;

    Sammanfattning : Chemicals are present in or have been used for production of a large number of products available for private consumers. There are many benefits and useful applications of chemicals, but risks and negative side-effects shall not be overlooked. LÄS MER

  5. 4. Use and environmental impact of antifouling paints in the Baltic Sea

    Författare :Maria Alexandra Bighiu; Ann-Kristin Eriksson-Wiklund; Bethanie Carney Almroth; Manu Soto; Stockholms universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; boats; antifouling paints; metals; XRF; in situ; caging; Theodoxus fluviatilis; toxicity; Applied Environmental Science; tillämpad miljövetenskap;

    Sammanfattning : Biocide-based antifouling (AF) paints are the most common method for preventing biofouling, i.e. the growth of algae, barnacles and other organisms on boat hulls. AF paints for leisure boats are predominantly based on copper (Cu) as the main biocide, with zinc (Zn) present as a pigment and stabilizer. LÄS MER

  7. 5. Towards Prospective Exposure Modeling of Nanoparticles - Applying Particle Flow Analysis and Kinetic Exposure Modeling for the Cases of TiO2 and Ag Nanoparticles

    Författare :Rickard Arvidsson; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; exposure modeling; environmental risk assessment; nanoparticles; Particle flow analysis PFA ;

    Sammanfattning : The claims regarding the usefulness of nanoparticles (NPs) in different applications, such as wound dressings, solar cells and soil remediation, has been accompanied by concern that NPs may also pose risks to humans and to the environment. Considering the past century, when many substances later shown to cause unacceptable damage were manufactured in large amounts, there are reasons to thoroughly assess the risks of these NPs. LÄS MER
