Water from this pond at the Alma Sugar Mill in Lakeland, La., is sampled monthly for algal growth ex
Producing energy pellets from dried animal waste and biomass Forestry and poultry, the top two income-producing agricultural commodities in Louisiana, generate significant quantities of waste that can be used for producing energy pellets or other value-added products such as soil amendments. The magnitude of waste from the poultry industry is the primary reason for concern. Because of the costs associated with hauling the material over long distances, poultry litter is often overapplied to nearby land, leading to excess nutrients and pathogens in runoff water. Therefore, generating energy from this waste and biomass is both economically logical and environmentally sustainable.

Impact of microalgae/cyanobacteria co-culture on sugar mill effluents: Water treatment and added value assessment. Presentation by Jacob Foy focuses on a case study on sugar mill effluents from the Alma Plantation Sugar Mill.

Use of Sugar Mill Effluents for Growth of Louisiana Co-Culture. This presentation, given by Jacob Foy, addresses the quality of wastewater from a sugar mill used to process feedstocks in to biofuels.

Characterization of sugar mill effluents for cultivation of microalgae/cyanobacteria co-culture. The objective of this study is to determine the suitability of sugar mill effluents from a Louisiana sugar mill for biomass production of a Louisiana native co-culture (Chlorella vulgaris/Leptolyngbya sp.).

Environmental Life Cycle Assessment. The Environmental Life Cycle Assessment (LCA) is a methodology that assesses environmental impacts and human risks from all of the steps in the production chain of a product or a service.

Life Cycle Greenhouse Gas Emissions, Fossil Energy Use and Eutrophication. The production of biofuels and commodity biochemicals relies mostly on fermentable carbohydrate from agricultural feedstocks. Choosing a low-environmental-impact feedstock for fermentable carbohydrate is an important part of establishing a sustainable biofuels and commodity-renewable chemical industry. This study looks at the environmental impact of energycane and sweet sorghum for use as biofuel/bioproduct crops.
