Energy generation from solid waste
Business Model Description
Invest in waste-to-energy plants to generate power for the State national grid and/or directly to industrial zones (B2B). The service price for solid waste treatment and the sales price of electricity is negotiated with local authorities. Flying ash from waste burning will be stabilized and buried; other solid, liquid, and gaseous wastes will be treated as per safety standards. Examples of companies active in this space are:
Everbright Waste to Energy plant: Launched in December 2018, the plant, Can Tho Waste Incineration Plant, has received and treated more than 400,000 tons of waste including domestic waste that has been buried in landfills, generating more than 113 million kWh of electricity for the national grid (21)
Soc Son Waste Power Plant was officially launched into operation. It has 3 incinerators with a capacity of 800 tons of waste per day and a generating capacity of 15MW (22)
Expected Impact
Waste electricity benefits communities and contributes to increasing electricity supply and reducing greenhouse gas emissions.

Country & Regions
- Vietnam: Countrywide
Sector Classification
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
varied by investment but usually complex due to involvement with multiple partners and challenging negotiation with provincial authorities/ municipalities.
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).

Energy generation from solid waste
Invest in waste-to-energy plants to generate power for the State national grid and/or directly to industrial zones (B2B). The service price for solid waste treatment and the sales price of electricity is negotiated with local authorities. Flying ash from waste burning will be stabilized and buried; other solid, liquid, and gaseous wastes will be treated as per safety standards. Examples of companies active in this space are:

Soc Son Waste Power Plant was officially launched into operation. It has 3 incinerators with a capacity of 800 tons of waste per day and a generating capacity of 15MW (22)
Business Case
Market Size and Environment
USD 100 million - USD 1 billion
The total potential of waste-to-energy power is about 1,100 MW (8)
Vietnam's total installed power capacity is 76,620 MW (23). The national revenue of the power system is nearly USD 17b (24)
Indicative Return
5% - 10%
Investment rate of waste power plant for the period 2020-2030: $2,270/kW for landfill gas recovery technology, using internal combustion engines for power generation and $4,000/kW for incineration technology(5)
Feed-in Tariff waste electricity purchase price for 20 years (excluding VAT): 10.05 US cents/kWh for direct incineration technology and 7.28 US cents/kWh for technology to burn gas from landfills (5)
The ADB's average IRR of advanced municipal waste-to-energy projects is 15% (concessional financing) (25)
Investment Timeframe
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)

Impact Case
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
11.6.1 Proportion of municipal solid waste collected and managed in controlled facilities out of total municipal waste generated, by cities
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)
By 2030, the percentage of urban domestic solid waste collected and treated up to the prescribed standards and standards is 95% (1)

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.
Impact Classification
What
Building a waste-to-energy plant to address environmental issues of the current burial and incineration methods, and increase the power supply of the national grid.
Who
People living near unsanitary land impacted by landfills benefit from improved living conditions.
Risk
