  1. 1. Cradle-to-Gate LCA of Water Treatment Alternatives : A case study performed for Norrvatten’s future waterwork expansion

    Master-uppsats, KTH/Hållbar utveckling, miljövetenskap och teknik

    Författare :Siddharth Selvarajan; [2021]
    Nyckelord :Life cycle assessment; Water purification method; Potable water production; Microbiological barrier; Activated carbon; Sludge separation; Livscykelbedömning; Vattenreningsmetod; Produktion av dricksvatten; Mikrobiologisk barriär; Aktivt kol; Slamavskiljnin;

    Sammanfattning : Norrvatten is a municipal association which owns a water treatment plant capable of supplying good quality drinking water to the consumers in the associated neighbouring municipalities. After preliminary investigations for the future year of 2050, there were estimates which suggest a potential water quality degradation in the lake which supplies the raw water for treatment due to uncertain future climatic conditions and other forms of pollutions from the surrounding.

    Master-uppsats, Karlstads universitet/Institutionen för ingenjörs- och kemivetenskaper (from 2013)

    Författare :Sandra Bergström; [2020]
    Nyckelord :Carbon dioxide capture; BECCS; CHP; bio-CCS; HPC; hot potassium carbonate; MEA; mono ethanol amine; carbon capture technologies; carbon dioxide; chemical absorption; carbon dioxide capture and storage; Koldioxidavskiljning; BECCS; kraftvärme; bio-CCS; HPC; kaliumkarbonat; MEA; mono etanol amin; avskiljningstekniker; koldioxid; kemisk absorption; koldioxidinfångning och lagring;

    Sammanfattning : BECCS (Bioenergy Carbon Capture and Storage) is an important part of measures to achieve zero net emissions globally by 2050, as the technology can create carbon sinks. However, the technology is very energy-intensive and expensive, and affects the existing systems at implementation. LÄS MER

  4. 3. Total Organic Carbon Reduction of Sorting by-Product Fractions

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

    Författare :Ahmad Abdul Rahman Al Saheb; [2020]
    Nyckelord :Total organic carbon; Loss on ignition; construction and demolition waste; TOC reduction; recycling; sequential separation treatment; converting waste to product;

    Sammanfattning : The drive of the EU countries and most of the world towards a circular economy and togenerate zero waste raised a need to study more efficient and less costly treatment processes. The treatment of secondary and by-product fractions to convert them from what is considered waste to a resource will contribute to the movement towards zero waste and circular economy. LÄS MER

  5. 4. Microwave Heat Treatment of Black Liquor for the Degradation of Hemicellulose

    Master-uppsats, Lunds universitet/Kemiteknik (CI)

    Författare :Maja Rydgård; [2020]
    Nyckelord :lignin; biofuel; black liquor; heat treatment; microwave heating; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Sammanfattning : The largest use of fossil petroleum is the production of fuels. Hence, finding sustainable alter-natives is an important step to reduce the emissions of greenhouse gases. One such alternative is to produce fuel from biomass, such as waste products from agriculture and the forest indus-try. LÄS MER

  7. 5. Drivers and barriers of successful climate commitment development in the fast-food industry The case of MAX Burgers

    Master-uppsats, Lunds universitet/Internationella miljöinstitutet

    Författare :Bairma Damdinova; [2020]
    Nyckelord :fast-food industry; business sustainability; climate action plan; climate responsibility; Social Sciences;

    Sammanfattning : Despite the fast food industry’s significant contribution to climate change, climate action plans are not common practice. Furthermore, there is a lack of academic works devoted to researching climate change issues within the fast-food industry. LÄS MER
