Construction Waste Reutilization

 

Circular Construction Materials for a Sustainable New Era

TCC is not only a leader in the cement industry but also a key advocate for low-carbon construction and the circular economy. 
With technical innovation at its core, TCC is committed to the recycling and reuse of construction waste, transforming waste into resources for sustainable development.

 

 

1

Separation and Recycling：Remove waste rebar and other non-reusable impurities to ensure stable quality of recycled aggregates and powder materials.

2

Crushing and Screening：Demolished building waste is processed through crushing, with aggregates of different particle sizes (such as 3/8" and 3/4" stones) and fine powder materials separated through advanced screening technology.

3

Regenerative Applications：Recycled coarse aggregates can be used as partial replacement material for concrete, while fine powder materials can serve as raw material or binding material to replace cement, applied in new building production to reduce carbon emissions.

4

Permeable Concrete Manufacturing：Some recycled construction materials can be used to produce permeable concrete, enhancing rainwater infiltration capacity and reducing the pressure on urban drainage.

Applications of Recycled Construction Materials

 

Permeable Concrete Pavement

 

TCC transforms waste concrete into Recycled Concrete Aggregate (RCA), which is used in road paving, such as permeable concrete pavement. Using construction waste as the coarse aggregate for the road's base layer, it demonstrates high durability and environmental adaptability, and enhances resilience to extreme rainfall and strong earthquakes. It has already been applied to roads surrounding the RRRC and energy storage site of TCC Green Energy.

Recycled Aggregates Concrete

 

In 2023, the strong earthquake in Turkey generated a large amount of construction waste. TCC's subsidiary, OYAK, rapidly invested capital to purchase machinery, enhancing the efficiency of construction waste processing and reuse. They are now using 100% recycled aggregates in concrete production, accelerating post-disaster cleanup and reconstruction.

Recycled Concrete

 

Located in Portugal, the Central Laboratory of TCC's subsidiary CIMPOR, is continuously developing more advanced "circular concrete". The goal is to remanufacture 100% of construction waste into new construction materials and actively promote "pre-carbonation treatment" technology, transforming concrete by-products into important carbon sinks.
