Malaysia’s Waste-to-Energy Shift: A Solution for Landfills or a Pollution Risk?
Malaysia is undergoing a significant transformation in how it manages its 40,000 tonnes of daily solid domestic waste. As the country’s 135 landfills face the threat of reaching full capacity by 2050, the government is turning to Waste-to-Energy (WTE) technology. By converting trash into electricity, officials hope to ease the strain on overburdened waste sites while boosting the nation’s renewable energy capacity.
Did you know? Malaysia aims to operate 18 WTE plants nationwide by 2040, which would contribute 600MW of renewable energy to the national grid—enough to potentially offset 2.5 per cent of the country’s current power supply.
Inside the Jeram Facility: Powering Homes with Trash
The flagship of this new strategy is the Jeram WTE incinerator in Selangor. Operated by Worldwide Sdn Bhd, the facility represents a major leap in waste management infrastructure. With an investment of RM1.2 billion (S$385 million), the plant is designed to incinerate 3,000 tonnes of waste daily once fully operational.
During a recent site tour, Selangor legislative watchdog head R. Rajiv observed the plant generating 29.8MW of electricity, exceeding its projected 25MW capacity. This output is expected to support at least 11,000 homes. The facility processes waste into electricity while recycling bottom ash for construction materials. However, toxic fly ash remains a critical component, requiring treatment with cement before it can be safely disposed of in a secure landfill area.
The Growing Debate: Innovation vs. Environmental Anxiety
Despite the promise of renewable energy, the WTE rollout has faced stiff resistance. Green groups and local residents have expressed concerns regarding potential health risks, traffic hazards, and the environmental impact of emissions. For instance, the Rawang Reject Incinerator Network gathered over 12,000 signatures in 2025 to oppose a proposed facility in Batu Arang.
Critics, including Greenpeace Malaysia zero waste campaigner Weng Dun Xin, argue that WTE plants may rely on “greenwashing” to mask environmental risks. Concerns center on the management of hazardous by-products like fly ash and the lack of transparent, continuous emissions data. Weng suggests that a more sustainable approach would prioritize waste separation at the source—composting organic waste and recycling materials—rather than relying on mass incineration.
Can Technology Overcome Past Failures?
Malaysia’s history with incinerators is cautionary. In 2014, the Parliament’s public accounts watchdog identified that four mini-incinerator projects in popular tourist destinations failed due to the use of unproven technology. Experts, such as Saman Ilankoon and Shafeeq Ahmed Syed Ali from Monash University Malaysia, suggest that current WTE projects offer a more sophisticated alternative, though they warn that public perception remains a hurdle.
Pro Tip: For large-scale infrastructure projects to succeed, authorities must engage in data-driven dialogues with local communities. Open communication regarding emission monitoring and safety protocols is essential to mitigate “not-in-my-backyard” (NIMBY) opposition.
Frequently Asked Questions
- What happens to the ash produced by WTE plants?
Bottom ash is recycled for use in road paving and construction. Toxic fly ash, which captures pollutants, must be treated with cement to comply with environmental standards before being sent to a secure landfill. - Does the Jeram plant segregate waste?
No, the current facility in Jeram does not segregate waste before the incineration process. - Why are residents concerned about WTE plants?
Concerns typically include potential air and water pollution, respiratory health risks from emissions, and the long-term management of hazardous waste by-products.
