Bennagen, Georgina Nepomuceno and Ramil Covar EXECUTIVE SUMMARY This studyexamines household waste management systems and the attitudes and behavior of selected middle-income communities in two haran gays' in Metro Manila. The factors that influence householdwaste segregation and composting are examined using descriptive statistics and regression analysis of primary survey data. The study identifies some household attitudes and behavior with regard to waste management that are important in designing community-based waste management programs, especially in the light of the country's new law on ecological solid waste management. The study also demonstrates the potential economic benefits from the adoption of resourcerecovery practices at the householdlevel. 1.0 INTRODUCTION Solid waste generation is an inevitable consequence
