Water and energy savings at every step

For 16 years, Veolia has been helping LG Lotte Petrochemicals significantly to reduce its energy and water use while increasing production capacity.

MOBILIZING ON BEHALF OF AN INDUSTRIAL GIANT IN SOUTH KOREA

With an output of more than 4.6 million metric tons of petroleum-based products in 2014, the 430-hectare Daesan industrial complex accounts for approximately a full 40% of South Korea’s petrochemical production. Veolia has been a partner to this industrial giant for more than 16 years, treating all industrial wastewater at the site and supplying drinking water to its 1,600 employees.
 

OUTPERFORMING LOCAL ENVIRONMENTAL STANDARDS

On obtaining the contract, Veolia assumed responsibility for the water treatment facilities at the site, and now also handles operation and maintenance for the production of reverse-osmosis water, demineralized water, cooling water and drinking water. The customer was seeking to operate the facilities more efficiently, reduce costs, shrink its water and carbon footprints, ensure compliance with quality standards and ensure reliable service. Veolia has fulfilled all those objectives, enabling LG Lotte Petrochemicals to surpass South Korea’s regulatory requirements for environmental performance. Energy efficiency at the site has risen from 80% to 95% over the 16-year period, while the volume of sludge produced has fallen from 85% to 65% and more than one third of cooling water is returned to the production process after treatment – a significant factor in reducing the site’s consumption of this precious resource in South Korea.
