Our commitment: Treat the water we discharge effectively



Our commitment: Treat the water we discharge effectively

We apply the most efficient technologies and methods to treat the water we use, prior to reuse or release into the environment. We are committed to treating the effluents from our operations in a responsible manner and adhere to strict quality requirements for returning it to the environment. In 2016, we strengthened our already demanding Nestlé Environmental Requirements (NER), including new water effluent parameters.

Our objective in 2016

By 2016: Implement the new and strengthened Nestlé Environmental Requirements for water quality and effluent discharge in all factories in order to help protect the environment.

Our progress to date

By the end of 2016, we reduced water discharge per tonne of product to 1.4 m3 per tonne, and improved the average water quality discharged to 72 mg COD (Chemical Oxygen Demand) per litre versus 2015. Over the last 10 years, we have reduced water discharge per tonne of product by 55%.

All our factories either have their own on‑site wastewater treatment plant or are linked to a local facility. Where required, we invest in our plants to keep them up to our NER, spending CHF 22.5 million in 2016 on their efficiency, conservation measures and on improved treatment facilities, as well as strengthening treatment requirements, or CHF 107 million since 2010.

We aim to minimise waste generation and recover value from by-products; more than 96% of sludge is recovered or reused. We have improved water effluents training and workshops in our operations and work with stakeholders to identify how to protect the environment.

Our objective towards 2020

By 2017: Monitor the implementation of the new and strengthened Nestlé Environmental Requirements for water quality and effluent discharge in all factories, in order to help protect the environment.
