Utilization of Fly Ash and Plastic Waste as Partial Replacement of Cement and Fine Aggregate in Concrete Paver Blocks
AI summary Read the abstract
Researchers investigated using fly ash and recycled plastic waste as partial replacements for cement and fine aggregate in concrete paver blocks, evaluating structural performance while addressing environmental concerns around both industrial byproducts and plastic pollution.
Fly ash primarily consists of finely divided unburned oxides generated during the combustion of coal. Fly ash is comprised of elements such as mercury, cadmium, and arsenic, which have the potential to contaminate waterways and the air, posing a threat to human...

Simultaneous Utilization of Fly Ash and Waste Plastics for Making Bricks and Paver Blocks
AI summary Read the abstract
Researchers developed paver blocks combining fly ash and waste plastics as a strategy for simultaneously diverting two industrial waste streams from landfill, assessing performance via hardness, wear, and compression testing. Safely immobilizing waste plastics in construction materials may prevent their fragmentation into microplastics and leaching of endocrine-disrupting chemicals like bisphenol A and phthalates into surrounding environments.
Suitability of Plastic Modified Asphalt Concrete (PMAC) in Sri Lankan Context
AI summary Read the abstract
This study evaluated the suitability of incorporating non-recyclable waste plastics — LDPE and BOPP — into asphalt concrete in Sri Lanka, testing performance characteristics and feasibility within local conditions. Incorporating plastic waste into road materials offers a potential diversion pathway that reduces the volume of plastic available to fragment into environmental microplastics, with implications for long-term pollution reduction.

Researchers evaluated the use of recycled plastic waste in road paver blocks in India, finding that incorporating recycled plastic improved block strength and weather resistance compared to conventional materials, offering a construction application for plastic waste.
Putting plastic waste management technologies into practice
AI summary Read the abstract
Researchers argued that achieving sustainable plastic waste management requires a systems-level approach that integrates mechanical, chemical, and biological recycling technologies rather than treating individual methods in isolation, emphasizing that no single technology can address the full complexity of the global plastic waste problem.
