Clean pulp making

Building on its use of plantations, APP China has developed advanced facilities for its pulp and paper enterprises as an integral part of its plantation-to-paper practice.

An APP China's subsidiary, Jinhai Pulp and Paper Co, China's largest pulp and paper producer, uses advanced technology and facilities in a comprehensive environmental management system that minimizes pollution and maximizes recycling of waste materials.

The company has invested in an eco-friendly alkali recycling system that not only recycles all the "black fluid" produced during pulping, but also makes use of the heat produced from burning it to generate electricity.

To minimize the discharge of wastewater from pulp bleaching, APP China's pulp mills cut the use of water and bleaching chemicals to a minimum by using state-of-the-art technology and equipment.

The wastewater discharged from these firms is well within national standards. The treated wastewater can even be used for irrigation or breeding fish.

Green papermaking

According to the China Environment Annuals 2002, the annual discharge from papermaking was 3.53 billion cu m, accounting for 18.2 percent of all industrial discharges. Chemical oxygen demand (COD) was 2.87 million tons, 40.8 percent of nation's total COD discharge.

APP China's investment of 4 billion yuan in eco-friendly technology and pollution control systems in all its papermaking plants has greatly reduced wastewater discharge and the negative impact of the papermaking industry on the environment.

APP China's largest subsidiary, Gold East, has improved efficiency in the use of energy and resources while putting an emphasis on recycling resources.

To produce one ton of paper, it uses only nine tons of water - one-sixth less than the national standard.

The recovery rate of white water from the papermaking process in Gold East Paper is 90 percent. Recycled water is used for removing dust, cleaning roads and irrigation.
