Sector

Infrastructure

Development needs
In 2018, 6.3% of the population in rural areas does not have access to sanitary water (1); 84.3% of solid waste from urban activities is collected and treated as per national standards, but this is mainly for landfills (2018), and the ratio is much lower in some regions (e.g. 63% in the Highlands) (2018) (2), social housing achieved 41.7% of the national target in 2020 (3)

Policy priority
as specified in the Socio-economic Development Strategy 2021-2030 of the Vietnam Communist Party, infrastructure development is one of the key strategic development pillars of the Vietnam government; the application of high and green technology and private sector participation is strongly encouraged by the government (4).

Gender inequalities and marginalization issues
Women account for half of the 64m population in rural areas (65% of Vietnam's total population) that suffers from underdeveloped infrastructure services, including pollution caused by solid waste, and unhygienic water supply (5, 6)

Investment opportunities introduction
Vietnam's waste management market was valued at USD 3.8 billion in 2020 (7), the potential of electricity generation from solid waste is estimated at 1,517 MW with an average power output of 10,617,740 GWh/year (8), and the investment demand in the water sector is estimated between $1.3 billion to $2.7 billion over the next 10 years (9).

Key bottlenecks introduction

Sub Sector

Waste Management

Development need
Vietnam lacks the adequate capacity to process solid waste: 75 % of collected solid waste went into landfills in 2020 and 80% of this is not compliant with sanitary standards (TCVN 6696:2000 by STAMEQ); the rate of waste collection is only approximately 40% and 60-80% in rural and urban areas respectively (2)

Policy priority
Decision 491/QD-TTg/2018 set out objectives for waste management wherein, by 2025, 90% and 80% of solid waste in urban and rural areas, respectively, will be collected and treated as per environmental standards, and the rate of directly buried waste will be less than 30%; 80% of waste from industrial activities is recycled and processed. (10)

Gender and marginalization issues
over 30 m women in rural areas (16) are suffering from improper processing of solid waste and limited access to clean water. Over 50,000 women are working in waste management and suffering from polluted working conditions that cause dangerous diseases, like respiratory tract or gastrointestinal infections (2). About 50% of solid waste in rural areas is not treated (11)

Investment opportunities introduction
(a) Solutions for solid waste recycling, (b) Application of advanced technologies for processing solid waste before going to landfills (The current investment in technologies is of low level; waste processing equipment/ machine is generally outdated causing environmental pollution), (c) Waste-to-energy generation

Key bottlenecks introduction
the service cost for solid waste processing and land access is defined by the negotiations with the local governments (provincial and municipal).

Investment Timeframe

Timeframe
Describes the time period in which the IOA will pay-back the invested resources. The estimate is based on asset expected lifetime as the IOA will start generating accumulated positive cash-flows.

Long Term (10+ years)

Due to a lack of specific guidelines for the implementation of the Planning Law, the additional new projects to the Power Development Plan are delayed. The procedures for investment in waste treatment are complicated and lengthy. E.g this process took the Nam Son plant (Hanoi) more than 3 years. (36)

Between investors, local municipalities, and the community, it takes time to negotiate and agree on the investment location due to concerns regarding the level of environmental pollution caused by the waste power plants.

This depends on size, construction scope, and technologies. Investors suggest the investment timeframe can be up to 10 years based on current market conditions. (26)

Market Risks & Scale Obstacles

Capital - CapEx Intensive

The waste-to-energy plants require a high level of technology to not cause an unfavorable impact on the environment. As a result, the investment amount is intensive (more than USD/MW) (5)

Market - High Level of Competition

Bidding is required for participation in the waste electricity market. At the same time, the construction of a waste power plant requires to be compliant with several legal procedures which vary across municipalities.

Business - Supply Chain Constraints

Waste in Vietnam is not sorted properly at sources, causing operational deficiencies (the calorific value of waste used for power generation must be 110 kcal/kg or more). In addition, the factory may not have enough waste volume to run at full capacity (8)

Impact Case

Read about impact metrics and social and environmental risks of the investment opportunity.

Sustainable Development Need

Approximately 75% of solid waste collected throughout the country is treated under the landfill method, of which about 80% is sanitarily disqualified, causing harm to the environment (2). Only 13% of waste is burned to recover energy (27).

Waste management is an important area contributing to the mitigation of greenhouse gas emissions (GHG), identified by the National Contribution Self-determined Country (NDC) of Vietnam.

Gender & Marginalisation

Domestic waste landfills are often located on the periphery of the city, and directly affect poor communities, resulting in the loss of alot of arable lands, along with air and water pollution.

Expected Development Outcome

Compared to the landfill method, waste electricity helps to reduce the volume of waste by 90-95%; power supply reduces greenhouse gas emissions; proper waste disposal reduces water pollution and bad odour. (27)

Gender & Marginalisation

Communities living near garbage power plants are less exposed to environmental pollution impacts resulting from landfilling (if the waste-to-energy solution is not applied). (27)

Primary SDGs addressed

Sustainable Cities and Communities (SDG 11)
11 - Sustainable Cities and Communities

11.6.1 Proportion of municipal solid waste collected and managed in controlled facilities out of total municipal waste generated, by cities

Current Value

Across Vietnam, there are more than 660 landfill sites, 69% (456 landfills) of which are unsanitary. More specifically, out of 98 centralized landfills operating in major cities, only 17 are sanitary. (28)

Target Value

By 2030, the percentage of urban domestic solid waste collected and treated up to the prescribed standards and standards is 95% (1)

Secondary SDGs addressed

Affordable and Clean Energy (SDG 7)
7 - Affordable and Clean Energy
Reduced Inequalities (SDG 10)
10 - Reduced Inequalities

Directly impacted stakeholders

Public sector

Reduce the budget burden of the municipal governments to invest in a waste treatment system.

Indirectly impacted stakeholders

People

People who sort waste at the collection sites and those who work in the existing landfills gain from improved working conditions in jobs in waste-to-energy plants.

Planet

Animals, both on land and in water, benefit from reduced hazards to their health by consuming waste, microplastics, and the like, in contaminated water.

Corporates

The power industry has alternative power sources with lower greenhouse gas emissions than existing coal-based power.

Public sector

Reduction in the Government's burden for protecting the environment in terms of biosecurity and food security.

Outcome Risks

A high rate of fly ash due to the use of the wrong technology and/or the fly ash landfill is not satisfactory for technical requirements.

Groundwater may get contaminated due to leakage of improperly treated waste, and harmful emissions may result due to operational management mistakes.

Dioxin formed during combustion may be above the allowable level if the right combustion technology is not applied in the beginning.

Gender inequality and/or marginalization risk: Investment risks will directly affect the people in areas where the plant is located, especially where there are a high number of vulnerable people.

Impact Risks

Air and water pollution is persistent due to inappropriate technology investment and/or improper operation.

Waste electricity investment is not attractive for scaleup because 3R classification and operation system (reduce, reuse, recycle) for household waste is not implemented efficiently.

Gender inequality and/or marginalization risk: If waste treatment does not meet the technical standards satisfactorily, the lives of vulnerable communities in the area will be adversely affected.
