    Sammanfattning : The fast breeder is a type of nuclear reactor that aroused much attention in the 1950s and 60s. Its ability to produce more nuclear fuel than it consumes offered promises of cheap and reliable energy, and thereby connected it to utopian ideas about an eternal supply of energy. LÄS MER

  4. 8. Integration of thermochemical processes with existing waste management industries to enhance biomethane production

    Författare :Chaudhary Awais Salman; Jinyue Yan; Eva Thorin; Yang Weihong; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; polygeneration; process integration; integrated biorefineries; biomethane; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : In most waste management industries, waste is separated into different fractions, each of which is treated with suitable processes. Established technologies such as waste combustion for combined heat and power (CHP) production and biomethane production through anaerobic digestion (AD) of biodegradable waste work fine as standalone processes.

  5. 9. Indigenous microalgae-activated sludge cultivation system for wastewater treatment

    Författare :Anbarasan Anbalagan; Emma Nehrenheim; Carl-Fredrik Lindberg; Sebastian Schwede; Raquel Labrero; Mälardalens högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Energy- and Environmental Engineering; energi- och miljöteknik;

    Sammanfattning : The municipal wastewater is mainly composed of water containing anthropogenic wastes that are rich in nutrients such as carbon, nitrogen and phosphorous. The cost for biological treatment of wastewater is increasing globally due to the population growth in urban cities. LÄS MER

  7. 10. Simulation of Indoor Radon and Energy Recovery Ventilation Systems in Residential Buildings

    Författare :Keramatollah Akbari; Konstantinos Kyprianidis; Anestis Kalfas; Mälardalens högskola; []
