Utilization of Waste Products in the Potato Processing Industry. 1. Wastes from Norwegian potato starch plants have been analyzed. The composition found is summarized. 2. An alkohol plant has been constructed to utilize the wastes from a potato starch factory. Later on this alkohol plant has been modified to utilize the wastes of a potato flake plant and a potato chips line. To make profitable use of the wastes, they have to be collected and concentrated. A system for this purpose is indicated. The mash of the alkohol plant is prepared in a continuous tube system. The fermentation and distillation are carried out in a conventional equipment. 3. A pilot plant for the removal of water from potato fruit water by evaporation has been built and tried out. The concentrate from the evaporator was dried in a Rotadisc dryer with waste pulp as carrying material and used in mixed feeding‐stuffs.
