Waste Treatment Facility Model for ERP Public Private Partnership

Waste Treatment Facility Model for ERP

On this page: Waste Treatment Facility leveraging a Existing-Build-Finance-Bulk-Tariffs model - Model 10 in the ERP Project Guidelines. Read more below, or visit Strategic Guidance for Country System Assessments, Guidance for Countries in Assessing ERC Projects, or Mobilizing ERC Finance.

Project Type: Landfill gas

Sector: Waste

Applicable Project Methodology: AM0025 – Avoided emissions from organic waste through alternative waste treatment processes

This project type aims to reduce methane emissions by setting up and running composting facilities. These facilities will treat organic matter obtained from municipal waste. The project's core activities include pre-sorting and categorizing municipal solid waste (MSW), recycling plastic waste, and subjecting the organic portion to thermal-aerobic treatment. The primary objective of the project is to generate aerobic compost from MSW, which would otherwise undergo anaerobic decomposition in waste landfills.

Proposed Structure of this Public Private Partnership (PPP) Model

The project will be leveraging a Existing-Build-Finance-Bulk-Tariffs model. An experienced waste treatment operator is provided the concession to receive pre-agreed daily volumes of waste from the government or state-owned entity landfill operator, in lieu of landfill tipping at no charge. The private sector entity in this case will be raising financing and building the waste treatment facility, after which the investment will be recovered through the sale of the by-products (e.g. compost material), as well as through the emission reduction credits (ERCs) generated and sold in the voluntary carbon markets.

Table 1: Model Attributes

Dimension	Attribute	Description
Business	New	This model assumes that the government or state-owned entity grantor will be granting a concession to an experienced waste treatment operator, potentially through a competitive bidding process.
Business	Existing
Construction	Build	The project involves the build of the new waste treatment facility in the vicinity of the landfill operated by the grantor.
Construction	Refurbish
Private Funding	Finance	The project company will be charged with raising financing for the new installation, both from financial institutions as well as the voluntary carbon markets.
Service	Bulk	Revenues of the project company will be sourced from contracted bulk purchasers of the waste treatment’s by-products.
Service	User
Revenues	Fees	Revenues in this model will be driven by the tariffs paid to the project company for the by-products produced by the waste treatment facility.
Revenues	Tariffs

Proposed risk allocation of the Public Private Partnership Model

Key features of PPP structure

Private sector entity to design, build, finance, operate and maintain MSW project via long- term agreement with the ministry/ government or state-owned entity
The private sector entity acts as the implementation partner, and is responsible for all activities related to the implementation, management, monitoring and reporting of the project over the project crediting period
In exchange, private sector entity can earn the revenues from the ERCs generated from the project
The government or state-owned entity benefits from the cost savings from not needing to treat municipal waste

Expected ERC end use

End use can belong to project developer as part of additional revenue stream

Key considerations/risks for proposed project

Extensive stakeholder engagement required to ensure buy-in from operators of landfill sites as well as any other relevant stakeholders
Need to ensure adequate technical local expertise in day-to-day execution to ensure minimal carbon leakage from treatment of MSW
Stable political environment key to enable smooth execution of MSW project
Partnering with a service provider for the project’s marketing, sales and pricing is needed to identify potential offset buyers, negotiate contracts, and secure good target price per tonne to enable the financial viability of ERC generation
Contracting a monitoring, verification and reporting (MRV) service provider with experience in conducting MRV and preparing the necessary documents for generating ERCs in a voluntary carbon market standard will reduce risk of registration and issuance delays or bottlenecks, and strengthen credibility of project’s carbon integrity quality

Case study: Vietstar Municipal Solid Waste Treatment Facility, Vietnam

Project description

The project will reduce methane emissions by establishing and operating composting facilities to treat organic matter collected from municipal waste. The total designed capacity of 432,000 tons of solid waste per year with daily waste reception of 1200 tons and the proposed product of organic compost as 53,568 tons annually.

The proposed project activity involves the pre-sorting, classification of municipal solid waste (MSW), recycling of plastic waste and thermal-aerobic treatment of the organic fraction utilizing LEMNA composting technology. The main purpose of the proposed project is to produce aerobic compost from MSW that would have been left to decay anaerobically in waste landfills.

Targeted results

Expected annual ERCs generated from the program will be 181,492 tonnes.

Figure 2: Structure of Case Study PPP

Vietstar Joint Stock Company, the project owner, operates a Public Private Partnership (PPP) with the Ho Chi Minh Department of Natural Resources and Environment (DONRE) via waste treatment contract signed between the two entities, agreed at $5¹ per tonne of waste treated.

Summary of the model financials

Assuming a similar project parameter as the case study, the project’s Net Present Value (NPV) without ERC in- and outflows – only considering non-ERC inflows through other revenue streams or cost savings enabled by the project – is $1.18 million (M), while the NPV of ERC in- and outflows alone is $6.68M, reflecting the significant value that generating ERCs from the project will bring. Considering all ERC and non-ERC cashflows, the project’s NPV is $7.87M, approximately 6.5 times of the NPV without ERC cashflows, which demonstrates a strong case for such project archetypes to consider generating ERCs.

Value component	Assumptions	Sources
ERC revenues or inflows	Three issuances across the project’s 10-year crediting period, at year 3, year 6 and year 10 $9.05 per tonne today for 604,976 estimated tonnes of ERCs likely generated in the first issuance 10% price increase to $9.95 for 1,209,952 estimated tonnes of ERCs likely generated for the second and third issuance	Average Gold Standard (GS) price of waste disposal in Asia from Allied Offsets database (2022)
Non-ERC revenues or inflows	$45 per ton of compost sold for 53,500 tons of compost produced per year, over 10-year crediting period $5 per ton of waste treated for plant capacity of 1200 tons per day and 360 days per year, over 10-year crediting period at maximum capacity $400 per ton of recycled plastic and 5,400 tons recycled per year over 10-year crediting period	Project Design Document (PDD) of the case study
