  1. 1. Separation and acidification of digested animal manure : properties of the future organic fertilizers

    University essay from SLU/Dept. of Soil and Environment

    Author : Marie Björs; [2023]
    Keywords : Digestate; Eutrophication; Farmers’ survey; Plasma activation; Screw press;

    Abstract : Agricultural areas with a high animal density contribute to eutrophication in waterbodies and seas worldwide due to accumulation of nutrients around animal farms. Animal manure is heavy and bulky, thus unpractical to transport long distances and new techniques have been developed to refine animal manure and make it easier to transport. READ MORE

  2. 2. Recovery of Cobalt and Copper from Zambia Slag via Sulphidisation with Gypsum

    University essay from KTH/Materialvetenskap

    Author : Lloyd Masuzyo Mseteka; [2021]
    Keywords : ;

    Abstract : The main objective of this research was to recover copper and cobalt from slags coming from copper processing on the Copperbelt province of Zambia. Pyrometallurgical processing of copper sulphide concentrate generates huge tonnes of slag wastes. READ MORE

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

    Author : Ghasem Mohammadkhani; [2021]
    Keywords : Chitosan fiber; Fungal fiber; Wet spinning; Hydrogel; Suture applications;

    Abstract : The aim of this project was to address the food waste problem, particularly bread waste, to some extent by producing monofilaments obtained from wet spinning of fungal hydrogel through the cultivation of Rhizopus delemar on bread waste. The project had two phases. READ MORE

  4. 4. Secondary aerosol formation from dimethyl sulfide - Smog chamber experiments and detailed process modelling

    University essay from Lunds universitet/Kärnfysik; Lunds universitet/Fysiska institutionen

    Author : Dana Lüdemann; [2020]
    Keywords : aerosol modelling; atmospheric physics and chemistry; marine aerosols; ADCHAM; aerosol; dimethyl sulfide; Physics and Astronomy;

    Abstract : The aim of this thesis was to investigate the secondary aerosol formation from dimethylsulfide (DMS) using the aerosol dynamics, gas- and particle-phase chemistry kinetic multi-layer model, ADCHAM. The first simulations, concerning the butanol oxidation via hydroxyl radicals (OH), were performed to characterize the UV-light source of the AURA smog chamber (Aarhus university, Denmark), later used for the DMS experiments.

  5. 5. Study of leaching behavior of tin in Zinc-clinker and Mixed Oxide

    University essay from Luleå tekniska universitet/Industriell miljö- och processteknik

    Author : Olle Bertilsson; [2018]
    Keywords : Leaching; tin; Sn; Zn-clinker; Mixed Oxide; sulfuric acid; Zn; residue; H2SO4; Boliden;

    Abstract : Due to the increasing usage of Sn in different electronics, such as solders and in touchscreens, together with Boliden Rönnskärs increased intake of electronic waste as a secondaryraw material, a Zn-containing product called Zn-clinker has increasing amounts of Sn. TheZn-clinker is shipped to Boliden Zn-smelter in Odda, where the Zn-clinker is mixed in withcalcine (roasted concentrate) and leached in several steps. READ MORE
