While consumption of potatoes has decreased, processed products
such as French fries, chips, and puree have experienced growing
popularity (ZMP, 2000). Losses caused by potato peeling range
from 15% to 40% their amount depending on the procedure applied,
i.e. steam, abrasion or lye peeling (Scieber et al., 2001). Plants peel
the potatoes as part of the production of crisps, instant potatoes
and similar products. The produced waste is 90 kg per Mg of influent
potatoes and is apportioned to 50 kg of potato skins, 30 kg
starch and 10 kg inert material. The downstream processing in
the potato crisp industry is illustrated in the following general
flowchart of Fig. 1 (Vlyssides et al., 2007).
