Research / Scholarly interests
Dr John J Milledge's current research interests are:
- The use of seaweed, primarily Sargassum (both S. muticum and holopelagic species), for fuel and biorefining. - Ongoing project involvement: Darwin Plus funded project, "Sustainable solutions for Sargassum inundations in Turks & Caicos". Previous project involvement: a) EPSRC-funded project entitled "MacroBioCrude: developing a potential integrated process design and establishing the energetic and techno-economic viability together with sustainability of large-scale marine-based biofuel in UK coastal regions." b) Higher Value Chemicals from plants (HVCfP) funded project, "Road Map for the Use of Sargassum muticum in high-value Bioactive Compound Discovery". c) HVCfP funded project, "Novel application of brown seaweed as an antibacterial coating for interdental drug delivery".
- The growth and processing of microalgae to produce biofuel, food and other high-value products. Current project involvement: 'Valgorize' (Valorisation of algae for a better taste) funded by Interreg-2-seas. Previous project involvement a) the Dfactory (the microalgae biorefinery) funded by the EU FP7. b) Interreg IVA Channel Project Ecotec 21, " Glycerol Fuel Supply Chain". c) AllGas, "Industrial-scale demonstration of sustainable algae cultures for biofuel production" supported by EU FP7
- Energy Balance of bioenergy and algal production processes.
- Anaerobic digestion.
- Hygienic design of food plant – with interest in the cleanability of stainless steel used as a food contact surface.
