In this process, red algae pulp was produced simultaneously at
10–11% yield by algal dry weight with superior physical properties
over the wood chemical pulp (Seo et al., 2010). Market price of
wood chemical pulp is usually much higher than that of ethanol,
and it is expected that the price of red algae pulp would be higher
than that of wood chemical pulp, if commercialized. Simultaneous
production of pulp and ethanol from red algae instead of ethanol
alone (Park et al., 2012) may improve the economics of the process
and preserve forests.
