Biogas is a mixture of methane and other gases. In its crude state, it contains carbon dioxide (CO2) that reduces its energy efficiency and hydrogen sulfide (H2S) that is toxic and highly corrosive. Because chemical methods of removal are expensive and environmentally hazardous, this project investigated an algal-based system to remove CO2 from biogas. An anaerobic digester was used to mimic landfill biogas. Iron oxide and an alkaline spray were used to remove H2S and CO2 respectively. The CO2-laden alkali solution was added to a helical photobioreactor where the algae metabolized the dissolved CO2 to generate algal biomass. Although technical issues prevented testing of the complete system for functionality, cost analysis was completed and showed that the system, in its current state, is not economically feasible. However, modifications may reduce operation costs.

The Marshall Islands, a small island developing nation, has a significant solid waste problem. The atoll environment of the Majuro, the capital of the Marshall Islands, is one of scarce land and overpopulation. Increasing Western influences has been a major factor in this solid waste problem. This problem has created health issues and is an impediment to the development of a tourism industry, which is essential to the development of economic opportunities. Responsibility for solid waste management in Majuro is divided between several governmental and non-governmental agencies. This system is dysfunctional as there is little or no cooperation between the agencies. Although many consultants have developed recommendations, no action has been taken. Developing an action plan to consolidate solid waste management under one authority is important to solving of this solid waste problem. This project proposes legislation creating a solid waste management authority that will have the power to regulate all aspects of solid waste and help implement education and awareness to the people of the Marshall Islands.
