Paragraph starter

The integration of recycled materials, such as recycled concrete aggregates and plastics, into construction offers a significant pathway towards reducing environmental impact. Research indicates that these materials can lead to substantial reductions in greenhouse gas emissions and energy consumption, while diverting waste from landfills. However, designers must be aware of potential limitations, including variability in material properties and the need for robust quality control and adherence to emerging standards to ensure performance and durability.
