  1. 36. Reuse and Recycling of Food Packaging - Odour Related Aspects of the Use and Misuse of PET Beverage Bottles

    Författare :Heléne Widén; Avdelningen för livsmedel och läkemedel; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Livsmedelsteknik; Food and drink technology; aroma transfer; reuse; recycling; migration; contaminants; post consumer material; food packaging; polyethylene terephthalate PET ;

    Sammanfattning : The reuse and closed-loop recycling of food packaging was studied in order to assess consumer safety and the sensory quality (e.g. taste and smell) of packaged food. LÄS MER

  3. 37. Sanitisation of faecal sludge by ammonia : treatment technology for safe reuse in agriculture

    Författare :Jörgen Fidjeland; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Faecal sludge contains valuable plant nutrients and can be used as a fertiliser in agriculture, instead of being emitted as a pollutant. As this involves a risk of pathogen transmission, it is crucial to inactivate the pathogens in faecal sludge. One treatment alternative is ammonia sanitisation, as uncharged ammonia (NH₃) inactivates pathogens. LÄS MER

  4. 38. Managing Collaborative Product Development : A Model for Identifying Key Factors in Product Development Projects

    Författare :Sofi Elfving; Mats Jackson; Björn Fagerström; Lars Bengtsson; Mälardalens högskola; []
    Nyckelord :Collaborative product development; Integrated product development; Concurrent engineering; Product development; Product design; Collaboration; Integration; Communication; Key factors; Decision-making; Knowledge transfer; Experience reuse; TECHNOLOGY; TEKNIKVETENSKAP; Innovation och design;

    Sammanfattning : The increasing complexity of products and systems today has forced new processes, methods, and tools for managing the development of products. It has also forced the development of complex organisations and diverse relationships among functions and peoples within product development organisations. This implies a need for integrated processes. LÄS MER

  5. 39. Immobilization of feruloyl esterases in mesoporous silica

    Författare :Christian Thörn; Chalmers tekniska högskola; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Mesoporous materials; Feruloyl esterases; Protein modeling; Biocatalysis; QCM-D; Hydroxycinnamic acids; Enzyme immobilization; Silica;

    Sammanfattning : Feruloyl esterases are a class of enzymes that can be used as biocatalysts for the modification of bioactive hydroxycinnamic acids. In industry, enzyme immobilization is often necessary to stabilize the enzymes and to allow their reuse. LÄS MER

  7. 40. Towards sustainable plastics : Microbial production of aromatic and aliphatic building blocks from biobased feedstock and plastic hydrolysate

    Författare :Oliver Englund Örn; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Cell factories; Biobased plastics; Protocatechuic acid; Adipic acid; 4-Hydroxybyratate; 1; 4-Butanediol; PBAT; Enzymatic recycling; Synthetic promoter library;

    Sammanfattning : The current plastic system is unsustainable and needs to change. Plastics are mainly produced from fossil feedstock, contributing to greenhouse gas emissions, and low rate of post-consumer recycling results in pollution on land and in oceans with high ecological impact, and huge loss of valuable material.
