Biogas Facilities Engineering
From Waste to Energy
EDOPEC provides comprehensive Engineering, Procurement, and Construction (EPC) services for the development of modern biogas facilities, transforming organic waste from agricultural, industrial, and municipal sources into sustainable and reliable energy.
Our multidisciplinary engineering team manages the entire project lifecycle—from feasibility studies and specification development to detailed engineering, automation, commissioning, and handover of fully operational plants. By integrating proven process technologies with robust safety and control systems, we deliver facilities optimized for maximum methane yield, operational stability, and environmental compliance.
