Recycling Systems

Wet Concret

Gulf Center provides advanced recycling solutions for the concrete production industry, in partnership with BIBCO© Germany — a global leader in concrete recycling technology.

Our Wet Concrete Recycling Systems are designed for ready-mix and precast plants, offering efficient recovery of returned concrete, process water, and aggregates.

From ready-mix reclaimers and grey-water treatment to filter presses, settling pits, and truck rinsing systems, Gulf Center delivers complete recycling setups that help clients reduce waste, save water, and meet environmental sustainability standards.

Efficient wet concrete recycling systems engineered to recover aggregates, sand, and process water — delivering sustainable, zero-waste solutions for ready-mix and precast plants.

Gulf Center provides two advanced systems for managing leftover ready-mix concrete and promoting sustainable production within concrete batching plants:

1. Reclaiming Systems (Open-Loop)

These systems allow aggregates and sand contained in returned ready-mix to be separated, cleaned, and reused in the batching process.
Process water is directed to settling pits, where it can also be reused.
The fine materials collected at the bottom are manually removed and disposed, making it an open-loop recycling approach.

2. Recycling Systems (Closed-Loop)

A complete closed-loop solution that integrates a reclaimer with a water treatment unit, enabling full reuse of aggregates, sand, and grey-water.
This results in zero discharge, eliminating the need for waste disposal and minimizing environmental impact.
All systems are engineered in partnership with BIBCO Germany
and designed for ready-mix and precast concrete plants operating in Kuwait and the GCC.

COMTEC & COMTEC Mobile Version Compact, high-performance recycling units available in both stationary and mobile configurations for maximum flexibility on-site
