  2. 1. Reducing household waste : A social practice perspective on Swedish household waste prevention

    Author : Mimmi Bissmont; Kerstin Sandell; Hans Bertil Wittgren; Malmö universitet; []
    Keywords : SAMHÄLLSVETENSKAP; SOCIAL SCIENCES;

    Abstract : This thesis studies household waste prevention from a social scienceperspective. Swedish waste management is efficient in handling wastebut has not succeeded in reducing its quantities, even though theissue of waste prevention is being raised at both international andnational levels.

  4. 2. Loss Minimisation in Dynamic Food Processes

    Author : Marcus Henningsson; Livsmedelsteknik; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Livsmedelsteknik; Food and drink technology; Teknik; Technological sciences; CFD; dual plane ERT; ERT; waste minimisation; loss; milk; density; sensor fusion; multivariate calibration; electrical resistance tomography; dairy process; turbidity; conductivity;

    Abstract : The overall aim of the present work was to reduce losses during product changes or during rinsing in continuous food processing, with particular attention to dairy plants. The concept of sensor fusion of common process instruments was implemented as a tool to monitor the milk and fat concentrations in a dairy processing line. READ MORE

  5. 3. A model of pH and redox buffer depletion in waste landfills

    Author : James Crawford; KTH; []
    Keywords : ;

    Abstract : The geochemical processes governing the release of heavymetal contaminants from solid waste materials have been studiedexperimentally and modelled using a mass balance approach. Theaim of the modelling work was to develop calculation tools thatcan be used to predict the release rate of heavy metals fromwaste heaps or landfills. READ MORE

  6. 4. Experimental Investigation of Refrigerant Charge Minimisation of a Small Capacity Heat Pump

    Author : W. Primal D. Fernando; Björn Palm; Alberto Gavallini; KTH; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; heat pump; propane; low-charge; Wilson plot method; minichannels; aluminium heat exhangers; single.phase flow; Mechanical and thermal engineering; Mekanisk och termisk energiteknik;

    Abstract : Enormous quantities of heat are available in air, soil, water, exhaust air from buildings, and in waste water of any kind. However these heat sources are use-less for heating purposes since their temperatures are lower than the tempera-ture required for heating. READ MORE

  7. 5. Improvement of Labour Performance and Productivity in Uganda´s Building Industry

    Author : Henry Mwanaki Alinaitwe; Byggproduktion; []
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; performance improvement; Labour productivity; building industry; Uganda;

    Abstract : Productivity of labour is particularly important especially in developing countries where most of the building work is still carried out on manual basis. Previous research has pointed out that productivity in the building industry is low and in some cases declining. READ MORE
