Plastic waste poses significant environmental challenges due to its inability to decompose naturally, necessitating recycling or reuse. A recent study explores using recycled plastic and biocharBiochar is a carbon-rich material created from biomass decomposition in low-oxygen conditions. It has important applications in environmental remediation, soil improvement, agriculture, carbon sequestration, energy storage, and sustainable materials, promoting efficiency and reducing waste in various contexts while addressing climate change challenges. More as partial substitutes for fine aggregates in concrete. The research assesses mechanical properties when incorporating waste plastic particles such as bottles, bags, and packaging materials, and evaluates various treatment methods, including shredding, melting, and chemical modification, to improve compatibility with concrete. Biochar, a carbon-rich material, is also examined for its potential to enhance concrete performance. A comparative analysis shows that concrete with a 20% replacement of shredded plastic maintains nearly the same strength (41 MPa) as conventional concrete. Replacements of 30% and 40% result in reduced strengths of 38 MPa and 35 MPa, respectively. Incorporating biochar and recycled plastic in concrete offers a promising solution for reducing plastic waste and improving material sustainability.
