  1. 1. Anaerobic Co-digestion of steam pretreated wheat straw and sewage sludge

    University essay from Lunds universitet/Bioteknik (master); Lunds universitet/Bioteknik (CI)

    Author : Virginia Tosi; [2021]
    Keywords : Anaerobic co-digestion; wheat straw pretreatment; nutrients availability; OLR; VFA acumulation; Biotechnology; Technology and Engineering;

    Abstract : Anaerobic digestion (AD) of wastes and residues is a widely applied and explored process. However, when the process is not optimized, inadequate concentrations of nutrients and inhibitory compounds are common and can lead to low maximum organic loading rates and increased risk of process problems, low organic dry solids degradation rate and reduced methane yields.

  2. 2. Study of a valorisation process for biomass industrial waste involving acid cooking and enzymatic hydrolysis

    University essay from KTH/Skolan för kemi, bioteknologi och hälsa (CBH)

    Author : Nicolas Brunet; [2020]
    Keywords : ;

    Abstract : Lignocellulosic biomass has potential to chip in the chemical and biofuels supplies in future societies,even though lignocellulose is a recalcitrant structure that has to be treated in several steps. After theirproper life cycle, wood-derived materials such as particleboards have few outcomes today apart fromenergy recovery for heat production. READ MORE

  3. 3. Microwave Heat Treatment of Black Liquor for the Degradation of Hemicellulose

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maja Rydgård; [2020]
    Keywords : lignin; biofuel; black liquor; heat treatment; microwave heating; chemical engineering; kemiteknik; Technology and Engineering; Chemistry;

    Abstract : The largest use of fossil petroleum is the production of fuels. Hence, finding sustainable alter-natives is an important step to reduce the emissions of greenhouse gases. One such alternative is to produce fuel from biomass, such as waste products from agriculture and the forest indus-try. READ MORE
