Project Overview

• Project Name: Xi’an Municipal Construction Waste Resource Recovery Plant

• Location: Xi’an, Shaanxi Province, China

• Date: May 2025

• Material handled: Mixed Construction & Demolition (C&D) Waste (Concrete, bricks, mortar)

• Final Output: High-purity recycled aggregates and finished eco-bricks/pavement tiles.

We help project owners design complete resource recovery chains, from initial debris sorting to final brick-making integration.

The Challenge: Urban Development vs. Waste Accumulation

As a rapidly growing metropolitan area, Xi’an faced a surge in construction debris. The challenge was not just to “sort” the waste, but to find a high-value downstream application that justified the investment in automated sorting technology.

Our Solution: Integrated Sorting & Resource Recovery

Guoxin Group implemented a heavy-duty [Construction Waste Sorting Machine] system designed to bridge the gap between demolition and reconstruction.

Phase 1: Heavy Fraction Separation

The system utilizes reinforced Trommel Screens and Air Separators to isolate heavy aggregates (concrete and bricks) from light impurities like wood, plastics, and dust.

• Recovery Rate: The line achieved over 95% purity for stone and brick fractions.

Phase 2: Recycled Aggregate Preparation

The sorted heavy materials are crushed and screened to produce standard-size recycled aggregates. These materials serve as the high-quality raw material for the onsite brick-making line.

Phase 3: High-Value “Brick-to-Brick” Recovery

Unlike projects that simply landfill sorted debris, this Xi’an project features an integrated brick-making unit.

• End Product: The recycled aggregates are mixed with cement and pressed into high-strength pavement bricks, permeable tiles, and standard construction bricks.

Project Impact & ROI

• Zero Landfill Goal: Significantly reduced the local government’s pressure on C&D waste disposal.

• Economic Value: By converting “debris” into “bricks,” the facility turned a disposal cost into a product revenue stream.

• Environmental Sustainability: Reduced the demand for natural river sand and quarried stone, aligning with green building standards.

Technical Highlights

• Dust Control: The plant features an integrated dust suppression system to ensure the facility meets strict urban environmental regulations.

• Automated Control: The entire sorting logic is managed via a centralized PLC system, requiring minimal labor while maintaining stable output quality.
