Evaluation of thermal storage materials for solar cooker
(Metropolia Ammattikorkeakoulu, 2014)
The performance of a solar thermal energy storage system using Lapland granite rock fragments 2-4 cm in diameter were assessed using a scaled-down model. The thesis deals with a selected medium that absorbs and stores solar ...
Ion exchange for natural organic matter removal
(Metropolia Ammattikorkeakoulu, 2014)
The purpose of this thesis was to evaluate the efficiency of different types of ion exchange resins in terms of natural organic matter (NOM) removal from drinking water.
The experimental part of this project was done ...
Nutrient Limitation of Phytoplankton in Helsinki Coastal Region
(Metropolia Ammattikorkeakoulu, 2014)
Bioassay factorial design experiments were carried out to study the limiting nutrient in Helsinki coastal area during the summer of 2013. The study also focused on finding out cost effective methods for modelling the ...
Sustainability Life Cycle Analysis of a Logistics Company : A case study of Itella Oy
(Metropolia Ammattikorkeakoulu, 2014)
It is now globally recognized that there is a critical need for human society to be ecologically sustainable. The decline in natural resources, pollution, and climate change are only a few factors of concern regarding the ...
CARBON FOOTPRINT ANALYSIS (CFPA) OF UPM FORMI USED IN BIOFORE CONCEPT CAR : Comparative CFPA of UPM ForMi and Acrylonitrile Butadiene Styrene (ABS) Assumed to be Used in Mass produced Biofore car
(Metropolia Ammattikorkeakoulu, 2014)
This thesis report is based on the cradle-to-grave carbon footprint (CFP) calculation performed on UPM ForMi GP20 that is used in ‘Biofore Concept Car’. A comparative cradle-to-gate CFP calculation was also performed on ...
Phosphorus Poisoning and Characterization of Al2O3 Based Support Material
(Metropolia Ammattikorkeakoulu, 2014)
Purpose of this thesis project was to study the effect of phosphorus poisoning on Al2O3 based support material. Al2O3 is widely used as a support material in natural gas oxidation catalysts as a part of support material. ...
Pressurised hot water extraction (PHWE) and alkaline extraction of spruce
(Metropolia Ammattikorkeakoulu, 2014)
Lignocellulosic biomass is among the potential renewable feedstock for the production of energy and chemicals. The pathway to biofuel from biomass involves four core steps: pretreatment, hydrolysis, fermentation, and ...
Mass flow calculation method for a thermal biosludge drier
(Metropolia Ammattikorkeakoulu, 2014)
Sludge generated at waste water treatment plant has to be disposed of. As generating site and disposal site are not necessarily in close proximity, reducing the sludge becomes pivotal to avoid unwanted transportation costs ...
Potential of microalgae for biofuel : An experimental study on the effects of light irradiance and photoperiod on the growth rate and lipid content in microalgae Phaeodactylum tricornutum
(Metropolia Ammattikorkeakoulu, 2014)
Microalgae appear as an alternative source of biofuel due to their oil content, metabolic flexibility, ability to grow in non-arable land and their ability to use fertilizers with 100% efficiency. To make the biodiesel ...
Effects of Mining and Hydropower on Metals in Surface Waters : Case: Nam Ngum
(Metropolia Ammattikorkeakoulu, 2014)
Nam Ngum, a river in Lao PDR, is experiencing rapid development of hydropower and mining. Hydropower dams may influence the water quality via sediment trapping and hydrology changes. They also create barriers for migration ...
