The Aim

To design a novel harvesting technique for the sustainable removal of algal biomass from open environmental systems prior to post-
processing of the biomass for energy / product recovery.

Objectives to achieving this aim

  • Conduct a comprehensive Literature Review focussing on algal harvesting methods that are currently used, and the possibilities offered through biomimicry concepts.

  • With the help of Scottish Water and/or SEPA, identify open environmental water systems in Scotland where algae are a problem, and retrieve samples to characterise the taxonomy in the lab.

  • Design a mechanical technique to aid in harvesting algae in a suitable state for anaerobic digestion, as well as other fuel refining processes.

  • Conduct a life cycle analysis to assess the sustainability of the technology.
Outline of the Case Study


Sustainable development meets the needs of the present without compromising the needs of future generations to meet their own needs.
