CONTEXT AND OBJECTIVES

Multi-level plant featuring conveying systems, water treatment lines, and glass refining processes. The objective was to ensure high-quality separation by color while reducing environmental impact through dust control and noise reduction measures.

SCOPE OF SUPPLY

·       Power and control electrical infrastructure: design and installation of LV switchboards, MCCs, and electrical backbones

·       Wiring of drives (VFDs) for motors, pumps, and fans, including programming

·       Dry commissioning, integration of safety logic, and preparation of signals for SCADA interfacing

PROCESS / PLANT ARCHITECTURE

Washing & Clarification

·       Local control panels for pumps and chemical dosing units (IBC), with pH, redox, turbidity, and level instrumentation

·       Electrical connections for GRP clarifiers and tanks; dedicated emergency power network and earthing system

Crushing

·       Power supply and speed control via VFDs for mills, vibrating screens, conveyors, and elevators

·       Control of ventilation and dust extraction systems

·       Speed/misalignment sensors and safety devices (limit switches, E-STOP pull cords); rotation tests and interlock verification

Pre-Sorting

·       Wiring of scalpers, windshifters, and overband magnetic separators

·       Control of transfer conveyors, fans, and ducting

·       Connection to local panels and interface with the central MCC

Sorting / Power Center

·       Supply and installation of LV main switchboards (LVMS/MCC), auxiliary service panels, and UPS for critical loads

·       Electrical backbones, cable trays, and floor-mounted conduits

·       Electrical provisions for optical sorting islands and metal detectors

SAFETY, TESTING, AND DOCUMENTATION

·       Integrated E-STOP network, protective interlocks, cable labeling, and full traceability

·       Equipotential earthing system and dry functional testing (rotation direction, current absorption)

·       Preparation of single-line diagrams and as-built documentation, including I/O lists for signal mapping

RESULTS AND BENEFITS

·       Lines ready for start-up with reliable LV power distribution and field automation

·       Compliance with CEI/EN standards and enhanced operational safety

·       Preparedness for integration with the client’s SCADA system for centralized control and traceability

·       High-quality cullet reducing raw material consumption and CO₂ emissions, aligned with European sustainability objectives
