  1. 21. APPRAISAL OF FOOD RESIDUE (WASTE) BASED FUEL BRIQUETTES IN DOMESTIC COOKING APPLICATIONS: A CASE STUDY OF UGANDA

    University essay from Högskolan i Gävle/Energisystem

    Author : WINFRED KAKOOZA ATEGEKA; [2017]
    Keywords : ;

    Abstract : The research focuses on developing and evaluating the performance of low cost, low technology food residue based fuel briquettes as an alternative to the widespread use of wood fuels (charcoal and firewood) for domestic cooking applications. In view of the declining accessibility of wood fuels, inadequate electrification coverage and ever-rising prices of cooking gas and kerosene in Uganda, harnessing energy from within reach, alternative sustainable energy sources such as food residues has been regarded as a viable solution to domestic cooking energy.

  3. 22. Mechanical behavior of a bio-based composite : influences of production conditions

    University essay from Linnéuniversitetet/Institutionen för byggteknik (BY)

    Author : Seyed Mazdak Hosseini Moghadam; Mohamed Alshihabi; [2016]
    Keywords : DuraPulp; polylactic acid PLA ; press time; load rate; mechanical properties; E-modulus; maximum strength.;

    Abstract : Some mechanical properties of DuraPulp, a bio-based, bio-degradable composite made from polylactic acid (PLA) and pulp fibers, were determined. Focus was put on the conditions during productions whereby three different press times were studied. Additionally, two different material compositions (PLA to fiber ratios) were used. READ MORE

  4. 23. Fractionation of textile fibres from denim jeans

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Gustaf Chroona; [2016]
    Keywords : Fractionation; Separation; Textile fibres; Jeans; Regenerated cellulose fibres; Fraktionering; Separation; Textilfibrer; Jeans; Regenererade cellulosafibrer;

    Abstract : The structure and composition of denim jeans is complex. In addition to cotton, which is the dominating type of textile fibre, there may be up to about 20 % synthetic fibres. The synthetic fibres are found in the sewing thread and in the elastic yarns that are used to make stretch denim jeans. READ MORE

  5. 24. Predictions of Pulp and Paper Properties Based on Fiber Morphology

    University essay from KTH/Skolan för kemivetenskap (CHE)

    Author : Sara Sundblad; [2015]
    Keywords : Pulp Refining; Tensile Index; Zero-span tensile index; Fiber Morphology; Linear Regression;

    Abstract : The aim is to investigate models that predicts the potential of pulp and evaluate the relevance of the zero-span tensile index within these. Two chemical pulps made from softwood and eucalyptus were refined in a Voith-beater with different energy input in order to study the change of fiber morphology signals and other pulp and paper properties.

  6. 25. The influence of pH on fiber and paper properties : Different pH levels during beating and sheet forming

    University essay from Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper

    Author : Jennie Jansson; [2015]
    Keywords : pH; beating; WRV; fiber charge;

    Abstract : The effect of pH on fiber and paper properties, during beating and sheet formation, was investigated for three different pulps. The pulps were pH adjusted to four different pH levels between 3 and 9. Isotropic laboratory sheet were made of both unbeaten and beaten pulps. READ MORE
