Project Overview

In the Nestlé ice cream production plant (D’onofrio), the washing process is constant in 40 maturation tanks and 11 lines of ice cream production with the Cleaning in Place (CIP) system. CIP consists in the circulation of washing liquids (water-acid and base), through machines, pipes and other equipment into a washing circuit. When CIP is applied, the blending of water, detergent and disinfectant passes through at high velocity and eliminates the waste in ice cream lines ...

In the Nestlé ice cream production plant (D’onofrio), the washing process is constant in 40 maturation tanks and 11 lines of ice cream production with the Cleaning in Place (CIP) system. CIP consists in the circulation of washing liquids (water-acid and base), through machines, pipes and other equipment into a washing circuit. When CIP is applied, the blending of water, detergent and disinfectant passes through at high velocity and eliminates the waste in ice cream lines and maturation tanks. During CIP washing process, there are 3 phases with water: first, there is a pre-rinsing phase to clean residues of ice cream preparation; the second phase consists on washing tanks after applying acid and base; and, third phase consists on a rinsing process. All the process used drinking water which was disposed to wastewater treatment plant and then to sewerage system. Nestle identified the opportunity to reuse water of the last washing phase, storing water between cycles to use it in the first washing phase. After implementing this project, water consumption decreased in 26,050 m3/year, saving water resources. Principal activities: implementation of a 3 m3 tank to store water from the last washing phase, installation of 20 meters of pipes to reinject residual water, change of CIP process control panel, consumption water monitoring (monthly).

Project Results

Reduction on water use 26,050 m3/year
