Microalgae - Energy Production and Wastewater Purification : Three Scenarios for Microalgae Cultivation in the Kujala Waste Management Center
The diminishing fossil fuels and the emission problems are increasing the effort to develop more sustainable and carbon-neutral energy resources. Microalgae are a promising resource of renewable energy such as biodiesel and biogas. Compared to the current biofuel production from food crops, microalgae grow fast, do not require arable land and can be cultivated in nutrient rich waste waters. The biofuel productivity of microalgae per hectare per year is many times higher than with other biofuel resources. This study is a part of the ALDIGA project (Algae from Wastewater for Combined Biodiesel and Biogas Production), which is developing a concept for closed circulation production of algae-based biofuel. The main focus is to make the process eco-efficient and cost-effective. The project participants are the Technical Research Center of Finland (VTT) as a leading partner, University of Helsinki (UH) (Lahti), Lahti University of Applied Sciences (LAMK), Häme University of Applied Sciences (HAMK) and Finland’s Environmental Administration (SYKE). The project is funded by the Finnish Funding Agency for Technology and Innovation (TEKES). Kujalan Komposti Oy, located in The Kujala Waste Management Center, is improving the level of its organic waste management and is currently undergoing an environmental impact assessment (EIA). This includes the designing of a biogas plant and a microalgae cultivation facility. ALDIGA is studying microalgae cultivation in the Kujala area’s wastewaters. This thesis strived to define the potential of microalgae cultivation in the Kujala area through three scenarios. Worst-case, Moderate and Optimal scenarios modeled the biomass productivity, area requirement and water requirement parameters in three different situations. This gave a range and understanding of the minimum and maximum capacity the Kujala area has. The results indicate that Kujala has a minimum of 40 tons per year and maximum of 1000 tons per year microalgae biomass productivity in its area. Water consumption for this is ...
