REPORTS TO: PSC-TVA Project Manager

Period Cover: October 1, 2022 to December 30, 2022

Plastic Smart Cities (PSC-TVA) Project for Manila City aims to reduce the plastic waste leakage in the open environment by 30% at the end of 2024. This will be done in close coordination with different stakeholders. After which, the project aims to integrate circular solutions into the City Plan of Action on Marine Litter. Results from the conducted baseline study showed the need for the following interventions: (1) policies on reducing plastic wastes, (2) business engagement and private sector participation for reducing plastic wastes, (3) identification and pilot of solutions on reduction, collection, and recycling of plastic wastes, (4) increased compliance of households on waste segregation, (5) increasing capacity of Material Recovery Facilities (MRFs), and (6) supporting local community enterprises engaged in plastic waste recovery and management. It will also be accompanied by cross-cutting activities such as trainings, communication, and monitoring.

The 2021 WWF-Philippines lead Waste Analysis and Characterization Study (WACS) in Manila City results showed that the current waste generation rate (WGR) of the city is about 0.707 kg/cap/day while the disposal rate (WDR) is 0.425 kg/cap/day. Most of the generated and disposed wastes in the city are biodegradables with food wastes being the highest. Plastic bags, despite being lightweight, dominate the plastic waste composition of both generated and disposed wastes.

The results of the baseline study also show that about 116,292 tons of plastic wastes are annually generated. A total of 86% or 100,099 tons of these generated plastic wastes are collected by both formal and informal sectors while the remaining 14% or 16,193 tons/year of plastics are considered as uncollected/unaccounted.

Nevertheless, about 24% of the total generated plastic wastes are unmanaged. About 13% or 15,254 tons of the plastic wastes are leaked to water systems, 10% or 11,100 tons are retained on land, and the remaining are burnt or found in storm drains. A significant number of potential leakages of plastics was identified from collection services and disposal facilities of about 2,969 tons and 8,887 tons, respectively.

With regards to waste collection in the city, the collection is done daily with two waste categories that are being collected on an alternating schedule – biodegradable and non-biodegradable. Biodegradable wastes are collected on Sundays, Mondays, Wednesdays, and Fridays while non-biodegradable wastes are collected on Tuesdays, Thursdays, and Saturdays. A private waste hauler has been contracted by City of Manila for the collection service of the city. Collection services are conducted on a regular time and schedule. Monitoring officers from the Department of Public Services (DPS) in each zone are deployed per collection truck trip to ensure that wastes are properly collected, and all assigned routes are covered.

Waste collection in the city is normally carried out in the early morning, in the afternoon, and in the evening to avoid causing traffic congestion in the busy streets of the city during rush hour and business operations. There are some cases, however, that some residents such as in Barangay 412 are not consistently able to give their waste to the collectors because the time of collection is too early. During the FGD, one of the concerns presented by the barangays in the waste collection is that the collection truck does not haul garbage in areas of the barangay with narrow roads.

Based on the results of the above-mentioned WACS and a series of Focus Group Discussions (FGDs) with Barangay Officials, WWF-Philippines has included in the list of project interventions for the implementation phase of the PSC-TVA Project the improvement of MRF capacities, river/estero waste collection system, organic waste treatment facilities and small waste collection vehicle.

WWF-Philippines will engage a Technical Consultant that will validate the initial study conducted by the Project, provide conceptual and architectural of MRF and recommendation for the improvement of organic waste treatment facility.


Specifically, the Fabricator will have the following responsibility:

  • Data Gathering and Review. Consultant will gather and review the following information and data in line with the study:
    • For Data Gathering:
      • Demographics of Select Barangays in the City of Manila;
      • Coordinates of the Project Site Boundaries;
      • Compost Production Data in Centralized MRF;
    • For Review:
      • Initial Study on the Assessment of Material Recovery Facilities and Systems Conducted by WWF in the City of Manila;
      • Solid Waste Management Baseline Studies of Manila City;
      • DOST-ITDI Composting Technology Operations and Maintenance Manual;
      • Existing Standards and Guidelines in MRF Design – Asian Development Bank MRF Tool Kit, US Environmental Protection Agency Manual for Waste Transfer Stations, and Illinois Recycling Association Best Operational Practices Manual for MRFs and Recycling Drop-off Facilities;
      • Existing As-Built Plans of Centralized MRF in Manila Zoo;
      • Existing Laws, Policies, Regulations, Ordinances, and Programs Related to the Study;
      • Other Related Literature and Secondary Data;
      • Availability of Junkshops, Model Operators, and Recyclers in the City.
  • Site Visits and Ocular Inspections. Site visits and ocular inspections will be conducted by the Consultant to gain vital information about the current situation and natural features in the area that may influence the outcome of the study.
  • Validation of Initial Study. The initial study on the assessment of existing MRF and MRS in the City of Manila conducted by WWF will be reviewed by consultant based on accuracy and completeness. Consultant will perform a desk study and will conduct necessary site visits to validate the assessment. This will examine if the initial study identifies the gaps and overlaps between the capacity of the MRFs and the waste generated in the study area. The recommended improvements and potential technologies to be applied in the MRFs will also be reviewed. Consultant will also assess the existing organic waste treatment in the Centralized MRF in Manila Zoo.
  • Conceptual and Architectural Design of the Clustered Barangay MRF. Consultant will develop the conceptual and architectural design of a clustered MRF for select barangays. Conceptual and architectural layouts of the clustered MRF will be designed using licensed Autodesk and other drawing software. Consultant will present the conceptual and architectural design of the MRFs to WWF Philippines and other relevant stakeholders for approval. Once the designs are approved, a report for the MRF will be submitted to the Client. The report may contain the layout of the facility, the operation and maintenance framework, the type of waste accepted, the mode of waste collection and transport to the MRF, and mode of disposal of rejects.
  • Recommendations to the Improvement of the Centralized MRF. Consultant will also recommend the renovation of Centralized MRF in consideration to the currently existing design and layout based on the assessment conducted during site visit.
  • Provide suggestions for those barangays that don’t have an area for MRF.
