Las Piñas Kitchen Wastes Project: Community-Based Composting
Transforming Kitchen Waste into Fertilizer, Las Piñas Inspires Green Solutions Across Metro Manila
The Las Piñas Kitchen Wastes Composting Project, pioneered by Senator Cynthia Villar and the Villar SIPAG Foundation, has become an internationally recognized model for sustainable urban waste management.
Through a network of 89 composting centers in barangays across Las Piñas, this initiative processes over 75% of kitchen waste, converting it into organic fertilizer that local farmers and gardeners use.

Keeping Up with our Trash
The project not only addresses the growing challenge of landfill waste by keeping organic material out of dumps but also cuts city waste management costs. Moreover, it also creates a more eco-friendly and economically efficient solution for cities around the country.
Beyond waste reduction, the Las Piñas Kitchen Wastes Composting Project promotes environmental education through partnerships with schools, encouraging residents to adopt sustainable practices. These educational efforts reinforce the project’s mission by teaching individuals and communities about the environmental and economic value of composting. As a result, the project has inspired similar community-based waste management initiatives throughout Metro Manila, highlighting its scalability and impact.
