Vietstar Sustainable Waste Treatment

Avoiding large-scale methane emissions and driving circularity


When organic waste starts to decompose it releases methane, a potent greenhouse gas. In the past, there has been a lack of measures to control greenhouse gas emissions from being released into the atmosphere from landfills in Vietnam.


Sustainable Development Goals

2. Zero Hunger

53,000+ tons of organic fertiliser

created annually, providing a sustainable recycled resource for farmers and reducing landfill

8. Decent work and economic growth

388 jobs created

in project implementation and operation, boosting local economies with new income streams

11. Sustainable communities and cities

432,000 tons of waste

collected and treated on average per year

13. Climate Action

181,000 tonnes of CO2e

on average reduced annually through sustainable waste handling and disposal activities

The Solution

This innovative project aims to address the environmental impact of municipal landfills by pre-sorting and classifying solid waste, recycling plastic and then treating remaining organic matter with advanced composting technology. To drive circularity the final product of organic compost is then sold as high-quality bio-fertilizer – producing over 53,000 tonnes each year. The facility treats 432,000 tons of solid waste per year, daily that’s around 1,200 tons.

How do we address waste?

In the era of disposable goods, the world generates at least 3.5 million tons of plastic and other solid waste a day, 10 times the amount a century ago, according to World Bank researchers. This needs to be addressed urgently, but it won't change overnight. In the meantime, this project is helping make Ho Chi Minh City's waste disposal a bit more sustainable. It sorts landfill, recycling as much as possible, like plastic and turns organic waste into compost to cut methane emissions.

Expanding capacity

The centre's capacity is doubled to process c.432,000 tons of solid waste per year! Almost 5% of this is plastic that is recycled using advanced Japanese technology, instead of going into the ground.


Project Progress

4th successful verification

The project completes its 4th successful verification under the Gold Standard. All the project's environmental and social impacts–such as creating fair, well-paid job opportunities for hundreds of people, are audited by a third-party, TÜV SÜD.

The Impact

By preventing methane emissions from being freely released, the project is helping to combat climate change. It also reduces the amount of waste going into landfill through a stringent recycling, which prevents soil contamination.The sustainable fertiliser creates jobs and supports local farmers as it improves soil productivity, contributing to economic sustainable development of the region. More jobs are created for operating the site and workers have the opportunity to increase their technical skills through training sessions. The technology used to treat the organic matter is not yet widely used in Vietnam, therefore this project is pioneering new innovative solutions to environmental challenges.


The recycling system converts waste into sustainable compost for local farmers.
