  2. 1. Ageing behaviour of steel slags in landfill liners

    Author : Silvia Diener; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : Steel slags are by-products of the steelmaking process. To avoid unnecessary disposal, e.g. into landfill, their chemical and physical properties should be exploited to support alternative uses. READ MORE

  4. 2. Accelerate ageing of refuse-derived-fuel (RDF) fly ashes

    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Other technology - Environmental engineering; Övriga teknikvetenskaper - Miljöteknik; Waste Science and Technology; Avfallsteknik;

    Abstract : Ashes have properties that can be exploited in various applications, e.g. some ashes can be used in the construction of barriers in a landfill final top cover. READ MORE

  5. 3. Pre-treatment of substrates for anaerobic digestion : potential and development needs

    Author : My Carlsson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : Substrate pre-treatment has been gaining interest in anaerobic digestion (AD) as a means to increase biogas yields with nowadays more diversified substrate sources. The objective of this thesis is to identify improvement potentials and development needs within applications of substrate pretreatment in anaerobic digestion (AD) based on literature and specific examples, with special focus on the impact assessment and exemplified by the case of electroporation(EP) pre-treatment.

  6. 4. Environmental assessment of bottom ash pre-treated with zero valent iron

    Author : Mirja Nilsson; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : Bottom ash has similar properties as crushed rocks and gravel, andcould replace some of the 40 million tonnesof virgin material used for road constructions each year.However, results presented in the literature indicate thatthe leaching of e.g. Cr, Cu, Mo, Pb and Zn can cause athreat to the sur rounding environment if the materialis used as it is.

  7. 5. Suitability of fly ash for construction and land applications

    Author : Evelina Brännvall; Luleå tekniska universitet; []
    Keywords : ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Waste Science and Technology; Avfallsteknik;

    Abstract : Municipal solid waste incineration fly ash is often landfilled or sent abroad for stabilization because it is considered a hazardous waste. These approaches to fly ash are both costly, and highlight the need for alternative and sustainable ash recycling. READ MORE
