Progress toward full water recycling at PrimeAsia
Leather manufacturing group PrimeAsia has reiterated its goal of using 100% recycled water in its tanneries by 2040.
Currently, the company recycles 58% of the water used in its production processes.
At its China facility, water treated in the on-site wastewater plant is clean enough to support koi fish in a pond outside the building. The water is recycled from leather manufacturing activities.
To achieve its recycling targets, PrimeAsia has invested in automation and new treatment technologies. In China, automation of the wastewater treatment plant has helped reduce chemical use and improve water quality. In Vietnam, the company has trialled a membrane bioreactor (MBR) system combined with ozone treatment. This process improves water quality and colour while reducing sludge output. The MBR system is expected to become fully operational in Vietnam later this year, with trials due to begin in China.
PrimeAsia has said it will continue to seek further technological improvements to support its environmental targets.
