This study investigated the influence of environmental culture on household solid waste management in Quebrada Verde, Pachacámac (2025). With a quantitative approach, basic type and non-experimental correlational-causal design, 178 residents were surveyed. The results showed that environmental culture significantly influences general waste management (coef. ,200, p < ,001), with notable effects on collection (χ² = 4.62, p = ,032) and, especially, on segregation (χ² = 7.72, p = ,005; coef. 1.015, p = ,035 for high levels), the latter being the most sensitive. No significant impact was found for transfer and transportation (χ² = 2.26, p = ,133), suggesting dependence on institutional factors. It is concluded that environmental culture is key to individual action but requires structural support for sustainable results.
