GRI 303: Water

Management approach

Although a scarce and especially valuable resource, water is an essential part of many of Interseroh’s services. Interseroh is very careful to utilise water sparingly in all of its processes. Over 85 percent of this water is used at non-administrative sites: for the washing of returnable transport packaging crates at locations operated by INTERSEROH Pool-System GmbH, for the cleaning of pre-shredded plastic waste, and for the swim-sink separation process used in plastics recycling at the plant in Eisenhüttenstadt.

As part of the environment programme, all sites are required to work continuously towards improving their environmental performance, and this includes working to reduce water consumption. Causes of avoidable water consumption such as leaking taps or pipes are resolved as quickly as possible. All employees are also encouraged to use water sparingly.

303-1: Water withdrawal by source

In 2018, Interseroh consumed approximately 129,365 m3 of water. This represents a year-on-year reduction of 30.6 percent.

This consumption is largely attributable to the increased water recovery at the Eisenhüttenstadt plant, where all the process water used in production is now recycled several times. The process water supply is used mainly to maintain the necessary water quality. This allowed this site to reduce its total water withdrawal by 47.3 percent compared with the previous year.

303-2: Water sources significantly affected by withdrawal of water

Interseroh sources its water from municipal and private utilities. No water is taken from other sources (such as a company-owned well).

303-3: Water recycled and reused

In 2018, Interseroh consumed approximately 129,365 m3 of water. Most of this was attributable to the Eisenhüttenstadt production plant, which consumed 51,145 m3 in 2018. To minimise water consumption, all process water is recirculated and reused several times. The use of recycled water saves 70 m³ of fresh water every hour. This works out at 403,200 m³ recycled water over the entire 2018 reporting year.
