Before the establishment of Shizong Huahai, Shizong's local planting forest area was less than 100,000 mu, and the forest area continued to decrease. Since year 2007 Shizong Huahai was established, the company has actively encouraged local forest farmers' enthusiasm of planting, which actively promoted the development of plantation forests and related industries, and boosted 80,000 forest farmers. By the end of 2016, the scale of local planting forests reached 1 million mu, showing a rapid growth trend.

While planting forests bring economic benefits, ecological benefits are also significantly improved. The 1 million mu plantation forest absorbs about 24 million tons of carbon dioxide every year, and the environmental protection effect is remarkable.

Our company's new project adopts the world's advanced German original environmental protection equipment. The total investment of environmental protection equipment in a single production line is about 20 million. Atmospheric emission standards are higher than the national standard. The actual particulate matter emissions 1.3935KG/h (GB: 3.5KG/h), formaldehyde 0.0625KG/h (GB: 0.26KG/h), sulfur dioxide (SO2) emissions 25.95mg/m³ (GB: 50mg/m³), nitrogen oxide (NOX) emission 93.4mg/m³ (GB: 100mg/m³). High sewage recycling rate.

Treezo improves production efficiency and reduce energy consumption by adopting world's advanced equipments, new processes and new methods.

The new paving production line makes the paving faster and better. The thermal energy center enhances the energy utilization efficiency, saves energy and reduces emissions. The continuous heat pressing production line greatly improves the efficiency. The new mixing rubber workshop makes the rubber mixing more uniform. Therefore quality of the products have been further improved.
