Growing plants: The natural evolution of petrochemical centers

TIANJIN - Deer, peacocks and ostriches bask in the warmth of the sun and wander outside their wooden houses, against the backdrop of a surrounding rockery, fishing pond and large green vegetation.

At first glance, one might be tempted to think it is a park, but it is actually a petrochemical plant of Sinopec Group, the country's leading petroleum refiner and oil products producer, which is operating on the site in northern China's Tianjin municipality.

Hundreds of pipelines are set up to connect various towers and refining equipment, which are busy producing oil and chemical products.
