|
Algae can provide a compelling alternative to traditional mechanical aeration systems used in bioremediation (or, wastewater treatment), which is not only cheaper but also environmentally friendly. Conventional wastewater treatment is extremely capital and energy-intensive, with high construction, maintenance, and operating costs, large labor requirements, high carbon emissions, and daily production of sludge. Sewage sludge is infectious and is typically disposed of in a landfill, where its further decomposition results in the emission of methane, a potent greenhouse gas. Algae can use inputs waste streams – municipal, agricultural, or industrial - including energy, CO2 and nutrients. All over the world, municipalities and utilities spend enormous sums of money to treat wastewater and sewage to remove pollutants and impurities. Some of the pollutants in the wastewater and sewage are nutrients on which algae thrive. In fact, certain algae strains that grow in sewage are high in oil content. The combined effects yield an interesting value proposition: use algae to bio-filter and clean nutrient-laden, CO2-heavy and low-oxygen water so it can be returned to the ecosystem or reused, while simultaneously producing oil and/or other high-value biomass.
BioVantage, together with its bioremediation partners, offers one of the most sustainable wastewater treatment, energy and nutrient recovery, and water reclamation solutions available. Worldwide, ~$150B are spent on waste water treatment solutions (Water: a Market of the Future, SAM Sustainable Asset Management AG, December 2007). In 2002 the EPA estimated capital needs for "clean water" (sanitation) in the US to be ~$19 B/year (The Clean Water and Drinking Water Infrastructure Gap Analysis of 2002). |
