  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.

The population explosion is driving massive urbanization and infrastructure developments across the globe, which result in huge demand for metals, especially steel. READ MORE

  3. 3. How Odd is Betelgeuse?

    University essay from Lunds universitet/Astronomi - Genomgår omorganisation

    Author : Martin Oshaughnessy; [2020]
    Keywords : Betelgeuse; runaway stars; stellar evolution; binary interactions; Physics and Astronomy;

    Abstract : The role of massive stars (those with masses greater than eight solar masses) in the chemical enrichment of galaxies and renewed star formation forms an important field of fundamental research in modern astrophysics. The complex nature of massive star evolution produces formidable challenges in furthering our understanding of the processes driving massive star evolution. READ MORE

  5. 5. Feeding the 45 million : substituting soybean protein with insect protein within EU poultry and egg production

    University essay from SLU/Dept. of Ecology

    Author : Douglas Hunter; [2019]
    Keywords : insects; insect production; livestock feed; entomophagy; land use; futures research; food security; energy security; black soldier fly; mealworm; house cricket; sustainable development;

    Abstract : A global population increasing both in number and in resource consumption per capita has resulted in food, livestock feed and energy crop demands that are increasingly difficult to meet on rapidly degrading soils within a diminishing available area of arable land. With further expansion of agricultural land infeasible and yield increases through further intensification insufficient to meet the scale of predicted crop demand, the use of insects as an animal feed has gained traction as a method of not only reducing competition for arable land, but also some of the detrimental environmental consequences of livestock and conventional feed production.
