    Sammanfattning : Ghana as a rapidly growing and urbanizing middle-income country is facing a number of challenges, including (1) implementing a sanitary, environmental-friendly, and economically-sound waste management system; (2) increasing its agricultural productivity in a sustainable way to meet the growing domestic food demand; and (3) providing livelihood opportunities in both rural and urban areas. Using the black soldier fly (BSF), a particularly beneficial insect, to locally and cost-effectively valorise abundant, high-impacting, and nutrient rich organic waste streams, such as food waste (FW) and faecal sludge (FS), into affordable and sustainable farming inputs like organic fertilizer and animal feed products, could tackle all these challenges at the same time.

  2. 17. När är gränsen nådd? : En kvalitativ studie om Barcelona

    Kandidat-uppsats, Södertörns högskola/Institutionen för naturvetenskap, miljö och teknik

    Författare :Nicole Lindsjö; Sanna Andersson; [2018]
    Nyckelord :Barcelona; urban tourism; mass tourism; behavior; sustainability; sustainable-development; carrying capacity; crowding and overcrowding; local residents; tourists.; Barcelona; urban turism; massturism; beteende; hållbarhet; hållbar-utveckling; bärkraft; trängsel; trångboddhet; lokalinvånare; turister.;

    Sammanfattning : Syfte: Mot bakgrund kring en ökad turism i europeiska storstäder (Statista, u.å.) har syftet med studien varit att studera Barcelona som exempel för att bidra med en djupare förståelse kring hur turister och lokalbefolkning uppfattar varandra i stadsmiljöer med högt turistantal.

  3. 18. Återbrukssystem för möbler i kommunal sektor - hinder och möjligheter för cirkulära lösningar

    Master-uppsats, Lunds universitet/Miljövetenskaplig utbildning

    Författare :Antonia Jonsson; [2017]
    Nyckelord :Återbrukssystem; Återbruk; Återbruk av Möbler; Kontorsmöbler; Återbruk i offentlig sektor; Återbruk i kommunal sektor; Cirkulär ekonomi; Re-use system; Re-use of furniture; Recycling of furniture; Mistra REES; Off2off; Earth and Environmental Sciences;

    Sammanfattning : With today’s consumption trends it has become important to use resources more efficient and work towards a more circular economy. Municipalities may do so by using a re-use system for furniture, which means that they can mediate their furniture via an IT software and re-use them within the organization. LÄS MER

  4. 19. Modeling and implementation of dense gas effects in a Lagrangian dispersion model

    Master-uppsats, Umeå universitet/Institutionen för fysik

    Författare :Niklas Brännlund; [2015]
    Nyckelord :Dense gas; Lagrangian dispersion model; Langevin equation; Stochastic modeling; Accidental releases;

    Sammanfattning : The use of hazardous toxic substances is very common in the industrial sector. The substances are often stored in tanks in storage compartments or transported between industrial premises. In case of an accident involving these substances, severe harm can affect both population and the environment. LÄS MER

  5. 20. The bearing capacity of Nordic soil

    Master-uppsats, KTH/Maskinkonstruktion (Inst.)

    Författare :Begoña Pla Rubio; [2015]
    Nyckelord :Bearing capacity; root reinforcement; shear test; COMSOL Multiphysics; Bekker; Bärkraft; rotförstärkning; skjuvtest; COMSOL Multiphysics; Bekker;

    Sammanfattning : Heavy forestry machines have great immediate effect on soil properties. This increases the interest to develop approaches that help understanding better the interaction between the forest machines and the terrain and consequently develop the forwarders to be gentle to the environment.
