<![CDATA[Ineffective management of green mussel shell waste could worsen environmental issues. Green mussel shell waste can be used as a bioaggregate because it contains 90% CaCO3, which is similar to limestone and is generally chemically inert. Seashells calcined at high temperatures and fine particle sizes exhibit limited reactivity. This study aimed to analyze the amount of green mussel shell waste produced, the performance of calcined green mussel shell bioaggregate, the optimal substitution of bioaggregate in pervious concrete paver blocks, the performance of pervious concrete paver blocks, and the influencing factors. The methods used were observational to calculate the amount of waste produced over eight consecutive days and experimental to determine the mechanical and physical performance of pervious concrete paver blocks with bioaggregate substitution levels of 0%, 6%, 12%, 18%, and 24% at a test age of 28 days. The production of green mussel shell waste in the 2025 planting season was 86.7 kg/day. The test results for pervious concrete paver blocks showed that the compressive strength, porosity, and permeability values were within the ranges recommended by ACI 522R-10, 2010 and SNI 03-0691-1996 for permeable concrete used as parking area pavement material.]]>
