Effective use of potatoes for water shortage, moisture of potato chips produced during potato chips manufacturing

"If you do not have water you can stop the potatoes,"Marie AntoinetteI think I did not say, the manufacturer of British potato chipsWalkersPossessPepsiCoAnnounced a policy to recover moisture from the potato chimney discharged from the chimney as steam during the potato chips manufacturing process and use it as a source of water for the factory.

Although it is still under development, it is aimed to replace all of the water and drinking water in the factory in the future, beginning with the provision of water to be used for washing potatoes etc. In the future, It is said that they are expected to be available as water resources.

"About 75% of the potatoes are moisture," says Martyn Seal, Environmental Preservation Director at PepsiCo Europe, so considering water resources were wasted in the midst of the nose, there is no hand that does not use this We felt it. "

75% of the potatoes are moisture, but potato chips deep-fried in crisp crust contain little water. The moisture is escaping as a steam from potatoes heated in the process of potato chips manufacturing, and it seems that this steam is currently exhausted from the chimney of the factory roof. PepsiCo is currently developing technology to recover and process this water vapor and to reuse it as industrial water used in processes such as washing, peeling and slicing potatoes,LancashireSkelmersdaleIt is said that the experiment has already been carried out at a factory in. It is said that 3,000 liters of water can be recovered from the stack at this factory per hour.

In PepsiCo it is anticipated that all of the four potato chips factories owned in the UK can be replaced with water recovered from potatoes and furthermore in the future the line of daily use water (drinking water) It seems to aim to be all derived from potatoes. The water that recovered the vapors from the potatoes is distilled water, which is already "clean water" in general tap water, but it is planned to be reused through further processes of removing impurities.

In addition, there is a possibility that it will become possible to provide it as a regional water resource if the factory's water resources become surplus, and even if you can not directly provide water, the factory of PepsiCo is now To avoid using main water source means that water resources available for community increase, it will be significant in areas where water shortage is a problem, Martyn Seal says.

PepsiCo will reduce water usage and carbon dioxide emissions by 50% over the next five years by introducing this potato water source project and the technology called "iCrop" aiming to target water and fertilizer to the necessary places at farmers We aim to be a goal.
