Demolition and construction waste can be repurposed into durable prefabricated
elements like curbs, interlocking pavers, and slabs for infrastructure and
landscaping. Recycled aggregates, made from crushed rubble, concrete, and
bricks, are combined with binders to create versatile, eco-friendly products. These
elements reduce reliance on virgin materials, lower CO₂ emissions, and promote a
circular economy. Properly treated, they match the durability and strength of
traditional materials, offering sustainable solutions for modern construction
projects.
Demolition and construction waste can be transformed into various prefabricated
elements, such as curbs, interlocking pavers, and other products used in outdoor
landscaping. Here's how these materials are integrated into the production of
such elements:
1. Curbs and Interlocking Pavers
● Recycled Aggregates: Rubble, concrete, bricks, and other construction
materials can be crushed into recycled aggregates. These aggregates are
then mixed with cement or other binders to create pavers and curbs.
● Manufacturing Interlocking Pavers: Recycled aggregates are mixed with
binders, then molded and compacted to produce interlocking pavers. Once
installed, these pavers stabilize each other due to their shape and are used
for driveways, courtyards, and parking lots.
● Benefits of Pavers Made from Recycled Materials: They provide a durable,
versatile, and aesthetically pleasing solution while being more
environmentally friendly.
2. Prefabricated Elements for Infrastructure and Landscaping
● Recycled Concrete Blocks and Slabs: Blocks and slabs can be
prefabricated from recycled concrete for use in walls, pathways, fences, and
even retaining walls.
● Sidewalk Curbs and Protective Elements: Demolition waste is reused to
create sidewalk curbs, lane separators, benches, and other urban elements.
● Green Space Slabs: Slabs made from recycled concrete are designed for
green spaces, allowing rainwater infiltration while promoting material
reuse.
Benefits of Using Recycled Prefabricated Elements
● Circular Economy: This approach closes the lifecycle loop of materials by
reintegrating them into construction instead of sending them to landfills.
● Reduced CO₂ Emissions: Producing new concrete is energy-intensive, so
using recycled concrete helps lower overall emissions.
● Durability and Strength: Elements made from recycled materials can be
as durable as those made from virgin materials, provided the aggregates
are properly sorted and treated.
This approach offers eco-friendly and cost-effective solutions in the construction
sector by repurposing demolition materials for new applications.
