    Sammanfattning : By rethinking wastewater treatment plants (WWTPs) as resource recovery facilities, it is possible to de- velop the next generation of WWTPs. Moreover, it allows to accomplish environmental goals, such as reducing the CO2 footprint, and comply with increasing effluent standards regarding the concentration of nitrogen in a more sustainable way.

  4. 23. Life cycle assessment of DHA produced by microalgae using food waste : Assessing global warming, fossil energy use and effects on biodiversity

    Master-uppsats, Uppsala universitet/Institutionen för geovetenskaper

    Författare :Louise Bartek; [2020]
    Nyckelord :Life cycle assessment LCA ; docosahexaenoic acid DHA ; biodiversity loss; volatile fatty acids VFA ; global warming; sustainable development; Livscykelanalys LCA ; dokosahexaensyra DHA ; biodiversitet; flyktiga fettsyror VFA ; global uppvärmning; hållbar utveckling;

    Sammanfattning : Biodiversity is a key component for life on Earth since it contributes to clean water, fresh air and food security. Today, fatty fish farmed in aquaculture is the main Omega 3 source consumed by humans, including the essential fatty acid docosahexaenoic acid (DHA). DHA origin from plants and accumulate in fish via the marine food web. LÄS MER

  5. 24. Study of a valorisation process forbiomass industrial waste involvingacid cooking and enzymatichydrolysis

    Master-uppsats, KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Författare :Nicolas Brunet; [2020]
    Nyckelord :;

    Sammanfattning : Lignocellulosic biomass has potential to chip in the chemical and biofuels supplies in future societies,even though lignocellulose is a recalcitrant structure that has to be treated in several steps. After theirproper life cycle, wood-derived materials such as particleboards have few outcomes today apart fromenergy recovery for heat production. LÄS MER

  7. 25. Bakteriell Cellulosa-tillverkning från Melass genom Kombucha-fermentering

    Master-uppsats, Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Författare :Adina Engström; [2019]
    Nyckelord :Bacterial Cellulose; Molasses; Kombucha;

    Sammanfattning : As the global plastic consumption is increasing, an innovative substitute for petroleum-based product must be developed towards a more sustainable society. Cellulose is the most abundant biopolymer on earth having potential because of its biodegradability and is produced from renewable resources. LÄS MER
