  1. 1. In-Situ Gold Resource Estimation Using Satellite Remote Sensing and Machine Learning in Defunct Tailing Storage Facilities (South Africa)

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Shenelle Agard; [2023]
    Keywords : tailings storage facility; critical raw materials; machine learning; mine valorisation;

    Abstract : The mining industry generates billions of tonnes of waste annually, which is often stored in tailings storage facilities (TSF). This waste is generated from the extraction of ore from surface or underground mines, as well as from metallurgical processing and low-grade stockpiles. READ MORE

  3. 2. Using biological conversion to increase the value of short-chain fatty acids by mixed cultures

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Elisabeth Beach; [2023]
    Keywords : Ethanol; Mixed culture; Volatile fatty acids; Anaerobic digestion;

    Abstract : The development of anaerobic digestion processes has gained recognition for its potential for producing volatile fatty acids alongside bio-alcohols. In addition, the fermentation process and the products produced from biological fermentation have the possibility to overcome the abundance of organic waste in our society, which is potentially immensely rich in untapped valuable potential products.

  4. 3. Production of filamentous fungal biomass on waste-derived volatile fatty acids for ruminant feed supplementation and it's in vitro digestion analysis

    University essay from Högskolan i Borås/Akademin för textil, teknik och ekonomi

    Author : Mohammadali Bouzarjomehr; [2022]
    Keywords : VFAs volatile-fatty-acids ; Fungi production; Feed production.; Fermentation processes; Aspergillus oryzae; A. oryzae fungal biomass; Sustainability; Rumen fluids; Evaluation of the digestibility of the produced fungal biomass; TT method analysis; Gas production method; Nylon bag method analysis;

    Abstract : Single cell proteins such as that of edible filamentous fungal biomass are considered as a promising sustainable source of animal feed supplementation. Filamentous fungi can be cultivated on different organic substrates including volatile fatty acids (VFAs) such as acetic, propionic, and butyric acids. READ MORE
