Taking steps forward in effluent waste management
The upgrades in Suzhou concerning the wastewater management ensure a consistent commitment to the environment at our manufacturing facility. We made the following changes to improve our effluent waste management:
- The bio-treatment system moved to the existing pond, utilizing self-generated energy to maintain process temperatures above 15°C. The benefit is that during the winter period no additional energy consumption is required to sustain bacterial activity.
- Due to the location of the effluent treatment plant (ETP) near a main road and bus station a closed system was created, preventing the release of undesired odors that cause hindrance to our neighbors. ETP exhaust is collected and passes through air treatment before it is discharged.
- Upgrades were made to the physical treatment of waste to reduce moisture in sludge cake by up to 25%, which decreases the volume of disposable waste and its added costs significantly.
- Easy maintenance was a key factor for the new facility. So during ETP maintenance, each individual aeration head can be lifted and replaced, without any interruption or impact on the processes.
These upgrades are another step for Stahl in making our operations more environmentally responsible, following our recent efforts in power generation at our manufacturing site in Brazil.
Blue skies, green land and clean rivers
The Chinese Government is committed to stimulate a more responsible industry with a policy for blue skies, green land and clean rivers. This is realized through new legislation and strict supervision on the implementation of these new policies. A new national standard for waste discharge control was also established to emphasize these goals. The upgraded facility in Suzhou now fully meets (and exceeds) these new environmental requirements.
Continuous focus on reducing our environmental footprint
Water and effluent management is one of the highest priority issues for Stahl. That is why we continuously monitor and innovate the consumption of water, energy and resources at our manufacturing sites. We continuously work to upgrade our facilities to increase efficiency and improve our work practices. Water management is one of the ongoing projects and Stahl is installing water treatment facilities at all our global sites not yet equipped with them. This way, we reduce the amount of wastewater sent to third-party treatment locations and improve our overall environmental footprint.
