(a) Measurement of variability of key MSW characteristics within and across unique MSW streams (b) Development of novel methods for rapid/real-time measurements. • (a) Improvements in productivity with traditional carbon dioxide (CO 2) supply 2 from ambient air. The Feedstock Technologies Topic Area will focus on the characterization of MSW streams. Projects will work on understanding MSW variability and informing the steps necessary to produce conversion-ready feedstock. The Advanced Algal Systems Topic Area looks to improve seasonal productivity of algae via a diverse portfolio of strains and improvement approaches. Projects will develop tools to accelerate current and future strain and cultivation improvements.
