Waste Minimization

Construction and demolition waste contribute heavily to landfills. Integrating recycled materials curbs waste generation and eases the burden on disposal sites.

Types of Recycled Materials

Recycled Concrete Aggregates

Crushed and reused concrete not only reduces landfill waste but also exhibits similar properties to traditional aggregates, making it an ideal choice.

Reclaimed Wood

Salvaged wood from old structures can be repurposed for various applications, lending a unique aesthetic to projects.

Recycled Metal

Scrap metal from various sources can be melted down and reformed into new structural components, saving energy and reducing mining activities.

Reused Masonry

Bricks and other masonry units salvaged from demolished buildings can find new life in construction, preserving their durability and character.

Incorporating Recycled Materials

Structural Applications

Recycled materials can be used in load-bearing elements like foundations and columns, proving their structural integrity.

Non-Structural Applications

In interior design and non-load-bearing elements, recycled materials offer an artistic touch while promoting sustainability.
