The Hai'an High-tech Industrial Development Zone – located in the county-level city of Hai'an in Nantong, East China's Jiangsu province – recently won national recognition.

It was designated as a national eco-friendly industrial park – one of the three in Jiangsu and the first one in Nantong to be so honored – in the 2021 list of green manufacturers announced on Dec 10 by the Ministry of Industry and Information Technology.

In recent years, the Hai'an high-tech zone has faithfully followed a low-carbon development concept and focused on developing eco-friendly plants, buildings and transport – to contribute to China's target of reaching peak carbon emissions by 2030 and carbon neutrality by 2060.

Last year, the proportion of days with good air quality in the zone was 85.5 percent. The water reuse rate and the industrial solid waste disposal rate – including hazardous waste – reached 33.33 percent and 97.94 percent, respectively.

Moreover, the zone has organized for 145 resident businesses to be equipped with solar power generators, biogas power generators and other renewable energy applications facilities.

China Tianying Inc (CNTY), a resident enterprise, specializes in the development of advanced incineration and pollution control, plasma gasification and melting and other related key technology research.

It broke the pre-existing foreign technology monopoly and has participated in industrial standards formulations, becoming an exemplar of Jiangsu's energy saving and environmental protection industrial cluster.

Centering on low-carbon development, another resident company – Xinyuan Group – has established a model base for the comprehensive utilization of silkworm and cocoon by-products, included in the second group of national models for the circular economy.
