Restoring biodiversity: for Sinopec, Veolia makes the ecological and the petrochemical go hand in hand

The Beijing Yanshan PetroChemicals (BYP) complex, one of the largest Chinese petroleum product manufacturing sites and a subsidiary of Asia’s leading oil and gas company, Sinopec, processes over ten million metric tons of crude oil per year. For several years, protecting the site’s natural ecosystem has been an absolute priority for the manufacturer, which has made it one of the pillars of its strategy. It has been spurred on in this regard by an array of draconian laws, regulations and standards enacted in 2011, particularly targeting the city of Beijing and its petrochemical industry!

To support it in this transition to more sustainable and responsible industrial practices, BYP chose Veolia, its partner since 2006 in managing the wastewater treatment and recovery facilities, as well as optimizing the entire water cycle. The challenge: restoring the NiuKouYu park’s derelict wetlands, by treating the wastewater from BYP’s site. Once reintroduced into these wetlands via “filtering” plants, the site’s treated wastewater thus undergoes a second natural treatment, ensuring that the ecosystems that depend on it will continue to thrive.

This vast area, encompassing eight hectares of wetlands, dry grasslands, ponds and willow forests, is home to a wealth of landscapes and ecosystems: plants, insects, amphibians, badgers, hares, rodents, etc. To restore biodiversity, Veolia has created 23 “terraces” near the petrochemical complex. Each of these terraces has specific vegetation carefully chosen for its purification qualities, in order to optimize the quality of the water entering the natural environment. Restoring the ecosystem has encouraged over fifty bird species to repopulate the area.

All the same, the park has also been designed to serve a social purpose: the site has become a hub of activity for the local communities. A popular leisure spot, it has attracted over 600,000 visitors since opening free to the public on November 1, 2017. Thanks to this type of exemplary action to promote biodiversity, Sinopec is now one of the top 10 Chinese companies heavily investing in reducing greenhouse gas emissions. And ranks among the country’s 50 greenest companies.
