GREENEVA has delivered Technical Approval (Persetujuan Teknis/Pertek) and Environmental Technical Details (Rincian Teknis/Rintek) assignments under national and subnational authorities, demonstrating strong capability in preparing technically robust and approvable documents.

In line with Government Regulation No. 22 of 2021, GREENEVA has led end-to-end processes from data collection and verification, pollution source characterization (wastewater, air emissions, B3), to technical calculations/modeling and evaluation of pollution control systems.

All outputs are structured, defensible, and implementation ready, with full support provided through the approval process up to the issuance of technical recommendations and directives from relevant authorities.
