4. 13. Pyrolysis profiles and global kinetics of tropical biomass : coconut and cashew nut shells

   Författare :Alberto Júlio Tsamba; KTH; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; thermogravimetry; cashew nut cocnut shells; pyrolysis; kinetics; Other materials science; Övrig teknisk materialvetenskap;

   Sammanfattning : Biomass has been recognised as renewable and environmentally friendly source of energy since decades. Tropical biomasses which are available in large quantities as residues in Latin America, Africa and Asia, have high energy potential for exploitation through thermochemical conversion process, as pyrolysis, gasification or combustion.

5. 14. Fungi-based biorefinery model for food industry waste : progress toward a circular economy

   Författare :Pedro Souza Filho; Satinder Kaur Brar; Högskolan i Borås; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; filamentous fungi; circular economy; biorefinery; food industry; fungal biomass; bioplastic; resource recovery; Resource Recovery; Resursåtervinning;

   Sammanfattning : The food industry, one of the most important industrial sectors worldwide, generates large amounts of biodegradable waste with high organic load. In recent years, the traditional management methods to treat this waste (e.g., landfilling) have been considered not suitable because they do not exploit the potential of the waste material. LÄS MER

7. 15. Characteristics of fresh and aged carbonaceous aerosol from anthropogenic combustion sources

   Författare :Erik Nordin; Ergonomi och aerosolteknologi; []
   Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Aerosol; biomass combustion; gasoline vehicle exhaust; polycyclic aromatic hydrocarbons; secondary organic aerosol; soot; mass-mobility relationship; emissions; toxicity;

   Sammanfattning : Emissions from anthropogenic combustion sources, such as light duty vehicles and small scale biomass combustion, contribute significantly to ambient aerosol particle concentrations both on local and global scales. These emissions have controlling impacts on public health and global climate. LÄS MER
