  1. 1. Synthesis and characterization of lactic acid-based elastomers

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

    Författare :Afsaneh Makhdoumi; [2023]
    Nyckelord :Lactic acid; Elastomer; Bio-based elastomer; Renewable resource;

    Sammanfattning : Synthesized polymer from bio-based and renewable resources reported as an attractive substitution for fossil-fuel based polymers. Therefore, this work has focused on using sustainable material for production of elastomers to reduce the environmental impact of fossil-based elastomers and overcome the shortage of non-renewable fuels.

    Sammanfattning : Överkonsumtionen av engångsartiklar i fossilbaserad plast är ett av dagens stora miljöproblem. Således finns en efterfrågan på strategier för framställning av biobaserade plaster i allmänhet och härdplaster i synnerhet. LÄS MER

  4. 3. Metabolically engineer the cyanobacterium Synechocystis sp. PCC 6803 to produce 1,2-propanediol

    Master-uppsats, Uppsala universitet/Institutionen för biologisk grundutbildning

    Författare :Hanna Stjernfeldt; [2022]
    Nyckelord :Cyanobacteria; Propanediol; Propylene glycol; Synthetic biology; Cyanobakterier; Propandiol; Propylenglykol; Syntetisk biologi;

    Sammanfattning : Climate change and its effects on our society is a steadily growing problem. In 2010, the industry sector accounted for more than 30% of the global greenhouse gas emissions. The chemical industry is one of the industrial subsectors responsible for the highest emissions of greenhouse gas. LÄS MER

  5. 4. Impact of Industry 4.0 on the Supply Chain of Zagros Petrochemical Company

    Magister-uppsats, Linnéuniversitetet/Institutionen för ekonomistyrning och logistik (ELO)

    Författare :Mynudden Zikria Bahar; Ghazal Rostami; [2021]
    Nyckelord :Supply Chain Management; Industry 4.0; Information and Communication Technology; Business Intelligence; Multi-Channel Network; Zagros Petrochemical Company;

    Sammanfattning : Industry 4.0 is a concept that emphasizes system and process automation, digitalization, and data interchange in the workplace. Its purpose is to create a smart factory that will cut lead times and increase system productivity by responding to client demand or unforeseen circumstances. LÄS MER

  7. 5. What's Next in Sustainable Acoustic Materials?

    Master-uppsats, Lunds universitet/Innovation

    Författare :Klas Hellqvist; Anna Andersson; [2020]
    Nyckelord :Sustainability; Acoustics; Materials; Sound Absorption; Technology and Engineering;

    Sammanfattning : As industries have begun to rethink the way they design, make and dispose of products for the purpose of sustainable development, manufacturers of acoustic products have been slow off the mark. The majority of acoustic products are still made of primarily virgin material made from petrochemical resources, which have a significant impact on the environment. LÄS MER
