  1. 21. Evaluation of natural materials in Sustainable Buildings : A potential solution to the European 2050 long-term strategy

    University essay from KTH/Skolan för industriell teknik och management (ITM)

    Author : Víctor de las Heras Reverte; [2021]
    Keywords : Straw-bale building; Rammed earth building; Sustainable construction; Natural Building Materials; Energy performance analysis; Energy performance optimization;

    Abstract : Today, buildings consume 40% of total energy demand in the EU and are responsible for 36% of GHG emissions. For this reason, and due to the delicate situation of climate change that planet Earth is experiencing, solutions are being sought to make the building sector more sustainable. READ MORE

  3. 22. 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.

  4. 23. Comparison of Different Wood Types for Use as a Porous Substrate in Denitrifying Woodchip Bioreactors

    University essay from Uppsala universitet/Institutionen för geovetenskaper

    Author : Erica Erikson; [2021]
    Keywords : denitrification; woodchip bioreactor; column experiments; denitrifikation; träflis-bioreaktor; kolonnexperiment;

    Abstract : Explosives used in the mining industry release nitrate into the environment, causing concerns for the water quality in local river-systems. One way of reducing the nitrate loading into the environment is through a woodchip bioreactor. READ MORE

  5. 24. Mimic Drinking from a Straw in a Lab Environment

    University essay from Lunds universitet/Innovation

    Author : Karoline Teigland; Ella von Matern; [2021]
    Keywords : plastic straws; children’s usage; mimic drinking; Tetra Pak; human stresses; Technology and Engineering;

    Abstract : In July 2021, single-use plastics will be banned from the European market, meaning that the plastic straws used with Tetra Pak’s portion packs will no longer be permitted. Therefore, Tetra Pak develops new straws, and it is important to test their functionality, something that previously has been done with panel tests. READ MORE

  6. 25. Alkaline wet oxidation of biorefinery lignin from wheat straw

    University essay from Lunds universitet/Kemiteknik (CI)

    Author : Maja Lindblad; [2021]
    Keywords : alkaline wet oxidation; lignin oxidation; wheat straw; chemical pretreatment; biorefinery lignin; anaerobic digestion; response surface-modelling; chemical engineering; Technology and Engineering;

    Abstract : Climate change and depletion of fossil resources have generated a need for energy production based on renewable resources such as lignocellulosic biomass. Agricultural residues, like wheat straw, is lignocellulosic biomass that could contribute to the energy supply if it was used for biogas production. READ MORE
