  1. 16. Fruit wastes to biomaterials : Development of biofilms and 3D objects in a circular economy system

    Författare :Veronika Bátori; Kristiina Oksman; Högskolan i Borås; []
    Nyckelord :apple pomace; biodegradable; bioplastics; circular economy; orange waste; resource recovery; Resource Recovery; Resursåtervinning;

    Sammanfattning : To address the current plastic pollution problem, the replacement of conventional plastics with bioplastics can be considered. Although the land use of crop cultivation for bioplastics is still negligible, there is an increasing interest in the utilisation of lignocellulosic waste products for the production of bioplastics.

  3. 17. Does fish health matter? The Utility of Biomarkers in Fish for Environmental Assessment

    Författare :Niklas Hanson; Göteborgs universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Biomarkers; Fish; Environmental monitoring; Ecological risk assessment; Rainbow trout; Perch;

    Sammanfattning : Two common strategies to assess exposure to environmental toxicants are to measure chemical concentrations in the environment and to examine the presence of certain species that are known to be sensit... merive to pollution. LÄS MER

  4. 18. Dioxin emissions from small-scale combustion of bio-fuel and household waste

    Författare :Björn Hedman; Stellan Marklund; Calle Nilsson; Brian Gullett; Umeå universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Source-sorted waste; Household waste; Textile; Biofuel; Firewood; Pellets; Combustion; Wood boiler; Pellet boiler; Backyard burning; Garden waste; PCDD F; dioxin; PCB; Emission factor; Källsorterat avfall; Hushållsavfall; Textil; Biobränsle; Ved; Pellets; Förbränning; Vedpanna; Pelletpanna; Trädgårdsavfall; PCDD F; dioxin; PCB; Emissionsfaktor; Environmental chemistry; Miljökemi;

    Sammanfattning : Denna avhandling behandlar rökgasutsläpp av persistenta organiska föroreningar, framförallt dioxiner, vid förbränning av fasta biobränslen och torrt hushållsavfall i relativt små anläggningar (5-600 kW) utan avancerad rökgasreningsteknik.Samförbränning av avfall och biobränsle i effektiva mindre biobränslepannor testades som en alternativ strategi till den vanligen förekommande storskaliga hanteringen och förbränningen fast hushållsavfall.

  5. 19. Interface design of biodegradable polyester/nanocellulose biocomposites via reactive melt processing: tailoring of polyester matrix

    Författare :Angelica Avella; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; aminolysis; cellulose nanocrystals; wet-feeding; crosslinking; poly ε-caprolactone ; biocomposites; reactive melt processing;

    Sammanfattning : Pushed by the societal awareness of plastic pollution, attempts are being made to find sustainable materials that can minimize the environmental impact of plastics. In this context, biocomposites based on biodegradable polymers and renewable lignocellulose are of interest. LÄS MER

  7. 20. Contamination in Swedich waste wood : environmental implications, sources and waste management strategies

    Författare :Joakim Krook; Linköpings universitet; []
    Nyckelord :TECHNOLOGY; TEKNIKVETENSKAP;

    Sammanfattning : Today, bulk materials, e.g. wood, plastic, steel, and concrete, are contaminated by hazardous substances such as heavy metals, causing environmental and resource problems during waste management. LÄS MER
