  1. 1. Refining the particulate matter airway deposition arising from indoor cooking-related biomass combustion for children in the Haramaya district in Ethiopia

    Master-uppsats, Lunds universitet/Ergonomi och aerosolteknologi

    Författare :Kasper Malmborn; [2023]
    Nyckelord :Air pollution exposure; charcoal; wood; animal dung; low-income setting epidemiology; Technology and Engineering;

    Sammanfattning : Background: Air pollution, a global issue affecting millions of individuals, is linked to adverse health effects on the respiratory system, but also to e.g., cancer and cardiovascular ailments. In low-income countries, cooking is often conducted by biomass-combustion, causing women and children to be exposed to high levels of indoor air pollution. LÄS MER

  3. 2. Quality of Spent Mushroom Compost Amended with Organic Material- Effect on Nutrient Content and Plant Growth

    Master-uppsats, SLU/Dept. of Biosystems and Technology (from 130101)

    Författare :Rasha Kamel; [2023]
    Nyckelord :Apple Waste; Wood Chips; Microbial Content; pH; Pseudomonas; General Bacterial Flora; General Fungal Flora; Electrical Conductivity; Nutrient Content; Bulk Density; Porosity; Water Holding Capacity;

    Sammanfattning : Peat, as a non-renewable growing media, poses environmental concerns due to extraction and decomposition processes, leading to increased greenhouse gas emissions. Alternatives growing media with potential to replace or reduce the use of peat are of great need. LÄS MER

  4. 3. Investigation of above-ground biomass with terrestrial laser scanning : A case study of Valls Hage in Gävle

    Magister-uppsats, Högskolan i Gävle/Samhällsbyggnad

    Författare :Mathias Billenberg; [2023]
    Nyckelord :TLS; tree species; QSM; AGB; volume; wood density; biomass; allometric; point cloud;

    Sammanfattning : The thesis investigates above-ground biomass (AGB) with terrestrial laser scanning (TLS) for estimating AGB in a study area in Valls Hage, Gävle. The study used TLS for field measurements to collect highly detailed point clouds of two tree species for AGB estimation and comparison against validation data. LÄS MER

  5. 4. Flexible Sector Coupling (FSC) of Electrical and Thermal Sectors via Thermal Energy Storage (TES) : A Case Study on Oskarshamn Energi

    Master-uppsats, KTH/Skolan för industriell teknik och management (ITM)

    Författare :Raúl Calvo García; Jose María Marín Arcos; [2023]
    Nyckelord :Flexible sector coupling FSC ; district heating DH ; thermal energy storage TES ; heat pump HP ; capacity optimization; dispatch optimization; open-access tools; Flexibel sektorkoppling; fjärrvärme; termisk energilagring; värmepump; kapacitetsoptimering; leveransoptimering; verktyg med öppen tillgång;

    Sammanfattning : The integration of distributed energy sources and systems is of high relevance for the transition towards a more sustainable energy system. Taking into consideration the  amount of emissions produced by the heating sector, which account for at least half of the energy demand in buildings, district heating systems have the potential to play a key role in the transition, by enabling the integration of various energy sources and provide flexible energy services to the grid.

  7. 5. The transition of reaction-to-fire behavior from biomass to corresponding biochar

    Uppsats för yrkesexamina på grundnivå, Luleå tekniska universitet/Institutionen för samhällsbyggnad och naturresurser

    Författare :Jacob Johansson; [2023]
    Nyckelord :biochar; biomass; heat release rate; reaction-to-fire;

    Sammanfattning : As of now, the environmental issue is very topical and there is also an underutilization of different biological material where these can be used in ways that are typically not thought of. One way to increase the degree of utilization is to convert various biomasses such as natural rubber, olive pits, wood chips, and reed pellets into biochar. LÄS MER
