In recent years, under China’s national “dual-carbon” strategy aimed at achieving carbon peaking and carbon neutrality, cities across the country have accelerated their green transformation. Among the key initiatives is the remediation of contaminated construction land, a critical task for urban sustainability and long-term environmental governance.
However, this is far from an easy undertaking. To ensure the safe and compliant use of contaminated land parcels, each site must undergo comprehensive soil pollution investigations and risk assessments. Every subsequent land-use decision relies heavily on accurate and reliable data as a fundamental basis.
For a long time, fragmented data systems across national and local authorities, inconsistent enterprise reporting practices, and non-unified data standards resulted in construction land information being scattered across different departments. This made effective monitoring and investigation difficult, while data circulation and sharing across processes were severely constrained. In addition, insufficient data structuring from field sampling and the lack of digital, quantifiable land classification and evaluation mechanisms further complicated regulatory oversight and governance.
To address these challenges, the Department of Ecology and Environment of Zhejiang Province partnered with Hyperchain Technology to build a digital platform for soil pollution risk management. The platform integrates data from local environmental authorities, natural resources departments, and grassroots administrative units to establish a centralized database. It supports a full-cycle evaluation system covering soil investigation, risk assessment, control measures, and remediation for construction land.
The core value of the platform lies in transforming fragmented data submissions from enterprises and regulatory bodies into a structured, analyzable database. Based on this data foundation, regulators can strengthen risk supervision and remediation efforts, strictly enforcing land access management for contaminated sites. The platform delivers an end-to-end digital workflow, combining offline data collection, online processing, and blockchain-based traceability, representing a comprehensive digital transformation of traditional regulatory processes.
To date, the platform has provided services to nearly 6,000 enterprise users, consolidated tens of thousands of land data records across Zhejiang Province, and brought more than 770 enterprises under unified regulatory management.
While urbanization leaves its mark on every era, each parcel of land remains a precious home we deeply cherish. Recognizing the scarcity and value of land resources, we maintain a respectful approach to nature and leverage technology to give back. Through digital innovation, we contribute to China’s broader vision of building a Digital China and advancing sustainable development.
