    Sammanfattning : Bauxite residue, also known as red mud, is produced in large quantities as a result of alumina refining (the first stage in aluminium production), and is one of the world’s most abundant and important industrial wastes. As demand for aluminium continues to increase and space to store this residue diminishes, the potential to utilise bauxite residue as a secondary resource is increasingly being considered by the alumina industry.

  3. 2. Valorisation of fish waste biomass through recovery of nutritional lipids and biogas

    Författare :Betty Mbatia; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; by-products; value addition; EPA; DHA; PUFA; biogas;

    Sammanfattning : Commercial fish catch in Eastern Africa is dominated by Nile Perch. Of the fish that is processed for human consumption, 30-40% is wasted. Currently, these wastes are not fully utilized; they are sold off at low price, converted to low valued products or left to decompose leading to environmental pollution and wastage of bioresource.

  4. 3. Prevention and valorisation of surplus bread at the supplier-retailer interface

    Författare :Pedro Brancoli; Clara Cicatiello; Högskolan i Borås; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Food waste; Life cycle assessment; Bread; Prevention; Valorisation; Resource Recovery; Resursåtervinning;

    Sammanfattning : The global food system is a major driver of many environmental impacts, particularly those related to climate change, biodiversity loss, and depletion of freshwater resources. These problems are aggravated by a substantial waste of food throughout the supply chain, where retailers are responsible for large quantities of waste. LÄS MER

  5. 4. Supermarket food waste : prevention and management with the focus on reduced waste for reduced carbon footprint

    Författare :Mattias Eriksson; Sveriges lantbruksuniversitet; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : Food waste occurs along the entire food supply chain and gives rise to great financial losses and waste of natural resources. The retail stage of the supply chain contributes significant masses of waste. Causes of this waste need to be identified before potential waste reduction measures can be designed, tested and evaluated. LÄS MER

  7. 5. Can we go circular? : On the multifaceted challenges of facilitating shredder fines valorisation in the Swedish context

    Författare :Tharaka Gunaratne; Joakim Krook; Hans Andersson; Rajib Sinha; Linköpings universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : In concomitance with the growing developments around the circular economy concept in the region, the resource recovery and recycling of industrial production residues is increasingly being envisaged in the European Union and its member states. The role of the recycling industry has become ever important in this context. LÄS MER
