    Sammanfattning : Plastproduktionen och användningen av plast ökar varje år i hela världen och detta är ett av världens största problem. Plaster är ett svårnedbrytbart ämne och processen kan ta hundratals år. Detta leder i sin tur till att plastackumuleringen orsakar skadlig påverkan på klimat, miljö och människor. LÄS MER

  3. 2. The effects of pH and biodegradation on polymer-based granules

    Master-uppsats, Lunds universitet/Bioteknik (master)

    Författare :Isak Svenningsson; [2021]
    Nyckelord :polymerteknik; biopolymer; bioteknik; Technology and Engineering; Biology and Life Sciences; Chemistry;

    Sammanfattning : The use of biopolymers instead of traditional fossil fuel based and non-biodegradable polymers is seen as a positive step forward towards a more environmentally friendly future. This project investigates a granule product that is used in a dishwashing system with the aim of gaining knowledge about how it is affected by the storage in between uses and its biodegradability.

  4. 3. Biomethanation of Red Algae from the Eutrophied Baltic Sea

    Master-uppsats, Tema vatten i natur och samhälle

    Författare :Rajib Biswas; [2009]
    Nyckelord :Anaerobic Digestion; Baltic Sea; Biogas; Codigestion; Eutrophication; Nutrients; Pretreatment; Red Algae; Ultrasound; Biodegradation; Renewable Energy; Environmental Science; Chemical Engineering; Environmental Engineering; Process Technology;

    Sammanfattning : In the semi-enclosed Baltic Sea, excessive filamentous macro-algal biomass growth as a result of eutrophication is an increasing environmental problem. Drifting huge masses of red algae of the genera Polysiphonia, Rhodomela, and Ceramium accumulate on the open shore, up to five tones of algae per meter beach. LÄS MER

  5. 4. Biodegradation of Aliphatic Chlorinated Hydrocarbon (PCE, TCE and DCE) in Contaminated Soil.

    Magister-uppsats, Institutionen för tema

    Författare :Aloysius Tibui; [2006]
    Nyckelord :Aerobic biodegradation; Anaerobic biodegradation; Inorganic fertilizers.; Chlorinated compounds; Tetrachloroethene PCE ; Trichloroethene TCE ; Dichloroethene DCE ; Mico-organisms; Methane; basis mineral medium; Gas Chromatography GC ;

    Sammanfattning : Soil bottles and soil slurry experiments were conducted to investigate the effect of some additives on the aerobic and anaerobic biodegradation of chlorinated aliphatic hydrocarbons; tetrachloroethylene (PCE), trichloroethylene (TCE) and dichloroethylene (DCE) in a contaminated soil from Startvätten AB Linköping Sweden. For the aerobic degradation study the soil sample was divided into two groups, one was fertilised. LÄS MER
