    Sammanfattning :  Cashew nut and coconut shells are two potential renewable and environmentally friendly energy sources that are commonly found as agro-industrial wastes in tropical countries. Despite this fact, they are not yet widely studied as such. LÄS MER

  3. 2. Enhancing the circular economy: Resource recovery through thermochemical conversion processes of landfill waste and biomass

    Författare :Ilman Nuran Zaini; Weihong Yang; Pär Jönsson; Ashwani K. Gupta; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; gasification; pyrolysis; waste-to-energy; landfill waste; hydrogen production; circular economy; municipal solid waste; Teknisk materialvetenskap; Materials Science and Engineering;

    Sammanfattning : Currently, the global economy looses a considerable amount of potential secondary raw materials from the disposed waste streams. Furthermore, the existing landfill sites that often do not have proper environmental protection technologies pose a long-lasting risk for the environment, which urge immediate actions for landfill remediations.

  4. 3. Automating condition monitoring of vegetation on railway trackbeds and embankments

    Författare :Roger G. Nyberg; Narendra K. Gupta; Mark S. Dougherty; Siril Yella; David J. Murray-Smith; Alistair Armitage; Högskolan Dalarna; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Complex Systems – Microdata Analysis; Komplexa system - mikrodataanalys;

    Sammanfattning : Vegetation growing on railway trackbeds and embankments present potential problems. The presence of vegetation threatens the safety of personnel inspecting the railway infrastructure. In addition vegetation growth clogs the ballast and results in inadequate track drainage which in turn could lead to the collapse of the railway embankment. LÄS MER
