Challenges, not Problems.
Harvesting algae from open environments is a major obstacle to large-scale production of algal biofuels. Current harvesting methods are species-specific requiring a monoculture, and either contribute to a net energy loss, or they render the algae unsuitable for anaerobic digestion.
Sustainable harvesting of algae from waste and eutrophic water would provide a low energy treatment solution.
Additionally, wastewater treatment processes have high energy inputs; using algae would present a low energy solution, if it could be harvested sustainably. Eutrophication remains a problem in freshwater systems and coastal water.

Algae as part of a closed loop system
|
The Problem
Currently the processes of producing energy and treating waste water are entirely linear, relying heavily on fossil fuels, and producing damaging waste products.
|
The Solution
The use of algae to both produce (bio)energy and treat wastewater eliminates the dependency on fossil fuels and facilitates a 'double' closed loop system.
