The results demonstrated that PPW, a by-product of the potato
industry, could be efficiently utilized for ethanol production with
simultaneous reduction of waste by-product. The production of
ethanol from PPW represents an alternative, readily manageable
option; the feasibility of implementing this technique will be further
investigated by means of a larger scale technico-economical
study. Moreover, the availability of manufacturers to become involved
in this project and to devote resources to its implementation
will provide a significant contribution.
Therefore, the sugars consumed were 16.55 g L1. Ethanol production
was 7.58 g L1 and ethanol yield corresponded to 91.6% the
max theoretical yield.
