Erratum to: Biowaste Reuse Through Composting: The Response of Barangay Holy Spirit in Quezon City, Philippines, to Solid-Waste Management

Abstract

Biowaste is the large volume of solid waste generated daily by households, and it presents environmental and health hazards if not reused. Composting is one of the best options for such reuse. This study documents biowaste generation and collection from households and reuse through composting in Barangay Holy Spirit, Quezon City, Philippines. This barangay (the smallest administrative unit) has made pioneering efforts in composting, having developed it from a simple process to a mechanized process. The barangay's composting has been integrated with its vegetable and flower urban garden, which serves as a demonstration and training center on how to provide livelihood opportunities and environmental benefits. However, to enhance the compost's marketability, issues relating to quality, such as the high organic carbon, high carbon-to-nitrogen ratio, and low levels of nitrogen, phosphorus, and potassium, need to be addressed. The barangay intends to boost compost production and sales, thereby increasing income, which can further improve the solid-waste management and increase staff salaries. Barangay Holy Spirit is one of the most developed barangays in terms of solid-waste management, and it can serve as a model for other barangays.
