Researchers found that coffee grounds can be transformed into biochar, which strengthens concrete, reduces waste, and promotes sustainability by replacing sand in construction, with further testing needed for large-scale use.
Researchers have discovered that coffee grounds, typically discarded in landfills, can be transformed into biochar through a heating process called pyrolysis.
This biochar can then be integrated into concrete, improving its strength and reducing environmental impact. By replacing part of the sand in concrete, this method lowers reliance on natural resources and promotes sustainable construction practices.
Additionally, using coffee grounds helps reduce organic waste and greenhouse gas emissions, offering environmental benefits.
Further testing is needed to ensure the material's durability for large-scale use, potentially transforming waste management and construction industries by turning waste into a valuable resource.
