  1. 16. Developing biofertilisers in Grenada from the residues of an anaerobic digestion plant using Sargassum seaweed : Evaluating how problematic Sargassum algae can be turned in to a resource in Caribbean states

    University essay from KTH/Hållbar utveckling, miljövetenskap och teknik

    Author : Danielle Crowter Elfving; Emma Stahre; [2022]
    Keywords : Sargassum Algae; Fertiliser; Biofertiliser; Anaerobic Digestion; Massblooming; Cultivation; Sargassotång; Gödsel; Biogödsel; Anaerobisk Nedbrytning; Massblomning; Odling;

    Abstract : The West Indies have during recent years been experiencing large quantities of washed up Sargassum seaweed on beaches and coastlines causing many issues for local communities such as unpleasant odours, making beaches inaccessible and largely affecting tourism and fisheries. The issue has caused money loss for the communities both in cleaning costs and decreasing incomes from tourism and fishing. READ MORE

  3. 17. Increase of biogas production by incorporating residual streams from agriculture

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Stephanie Fjäll; [2022]
    Keywords : Anaerobic digestion; Agricultural residue; Lignocellulosic biomass; Mechanical pretreatment; Biogas production; Biorefinery; Chemical engineering; Agriculture and Food Sciences; Technology and Engineering;

    Abstract : To expand the biogas production in Region Västra Götaland (RVG), residual streams from the agricultural sector can function as a large-scale supplier of biomass. The production of biogas decreases the dependence of fossil fuels and the digestate that is formed can also be returned to the agricultural sector, creating a closed loop. READ MORE

  5. 19. Analysis and modelling of ozone pre-treatment of sludge for biogas production

    University essay from KTH/Kemiteknik

    Author : Gokul Prasad; [2022]
    Keywords : Wastewater treatment; anaerobic digestion; sludge pre-treatment; ozonation; methane; Avloppsvattenrening; anaerob rötning; slamförbehandling; ozonering; metan;

    Abstract : Ozonförbehandling av avloppsvattenslam har diskuterats i litteraturen som en potentiell metod för att öka biogasproduktionen och minska slamvolymen. I detta arbete utvecklades en numerisk modell för att simulera effekten av ozonförbehandling på biogasproduktion genom anaerobrötning. Modellen bygger på en befintlig modell från litteraturen.

  6. 20. Energy recovery through anaerobic co-digestion of food waste and wastewater treatment sludge : A proposition of a water treatment and biogas plant for a floating island in Stockholm.

    University essay from Linnéuniversitetet/Institutionen för byggd miljö och energiteknik (BET)

    Author : Rodrigo Bahena; [2022]
    Keywords : ;

    Abstract : The urge for more sustainable living motivated the Stockholm Tiny House Expo. The project aims to build a floating, sustainable, man-made island for living and working outside of Stockholm. This paper proposes a waste management method with possible energy recovery for the island. READ MORE
