Abstract

The research investigated the impact of the Quezon City Trash-to-Cash Back (TTCB) program on household solid waste segregation, employing key informant interviews, logistic regression modeling, propensity score matching (PSM), and robustness checks. Key informant interviews with Quezon City officials provided insights into the TTCB program's objectives and operations. Household survey data revealed disparities between participating and non-participating households, with participating households exhibiting higher levels of solid waste segregation and distinct demographic and socioeconomic profiles. Tobit regression analysis identified economic incentives, pro-environmental intrinsic motivation, and action planning as significant predictors of solid waste segregation behavior. Propensity score matching ensured balance between treatment and control groups, facilitating estimation of the Average Treatment Effect on the Treated (ATET). Results indicated a statistically significant positive ATET, with participating households segregating 8.30 percent more household solid waste (HSW) weekly compared to non-participating households. Robustness checks, including direct nearest neighbor matching and alternative matching techniques, validated the primary findings, confirming the effectiveness of economic incentives in promoting HSW segregation. In conclusion, the research underscored the importance of economic incentives in incentivizing sustainable waste management practices within the TTCB program. The findings could contribute to understanding waste management strategies and inform policy decisions aimed at enhancing environmental sustainability and mitigating solid waste accumulation.
