  1. 1. Clean development Mechanism (CDM) Policy and Implementation in China

    Författare :Lei Zeng; Leif Gustavsson; Mälardalens högskola; []
    Nyckelord :Climate change; Clean development mechanism; CDM; CO2; Green House Gas; GHG; landfill gas; sustainable development; China; Energi- och miljöteknik;

    Sammanfattning : China is the second largest emitter of greenhouse gases (GHG) in the world. Since 68% of its primary energy is from coal, China’s average energy intensity is 7.5 times higher than the EU and 4.3 times higher than the US (EU, 2003). LÄS MER

  3. 2. Reducing Radon Gas Emissions in Concrete

    Författare :Magnus Döse; Johan Silfwerbrand; Franz Josef Maringer; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Radon gas; emissions; health; concrete; building materials; ionizing radiation; Betongbyggnad; Concrete Structures;

    Sammanfattning : Several compulsory regulations and recommendations regarding ionising radiation for building products have been introduced in recent years. Furthermore, industry-affiliated aggregate and concrete companies strive to implement environmental goals that should be fulfilled regarding building materials. LÄS MER

  4. 3. Innovative Contact Free Sensors for Metallurgical Process Control

    Författare :Donald Malmberg; Stuart M. Millman; Högskolan i Halmstad; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; microwave spectroscopy; laser; TDLAS; high temperature; gas; slag; NATURAL SCIENCES; NATURVETENSKAP; spectroscopy; slag analysis; high temperatures; Mät- och instrumenteringsteknik; Instrumentation technology; TDLAS; microwave; laser; Fysicumarkivet A:2003:Malmberg;

    Sammanfattning : The steel- and metal industry has an extensive production processing comprising many different process steps of solid, gaseous and liquid nature. Thus it is obvious that a number of different measurement technologies must be used to collect and evaluate key physical parameters which are necessary to control the production processes. LÄS MER

  5. 4. Integration of a hemicelluloses extraction step into a forest biorefinery for production of green chemicals

    Författare :Jonas Helmerius; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Biokemisk processteknik; Biochemical Process Engineering;

    Sammanfattning : Sustainable use of forest and agricultural resources will play an important role for solving urgent global challenges such as the enhanced green house effect and increasing demand for fossil fuels. The development of processes where lignocellulosic biomass can be refined to several different end-products in the same plant, i.e. LÄS MER

  7. 5. Developments in Feedstock Analysis and Process Control for Biogas Production

    Författare :Sten Strömberg; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Anaerobic digestion; Process control; Biochemical Methane Potential; Process analysis; Feedstock; Biogas;

    Sammanfattning : A sustainable treatment of organic wastes, generation of renewable energy, reduction of green house gas emissions, limiting the eutrophication and closing the nutrient cycles are several environmental challenges for which anaerobic digestion may be a suitable solution. There is today a large amount of available organic waste materials that could serve as potential feedstock for biogas production. LÄS MER
