Introduction

Southeast Asia is in the midst of an extraordinary transformation. In just a few decades, rice paddies and fishing villages have given way to bustling megacities, glittering skyscrapers and digital economies. By 2030, 405 million individuals, representing 55.6% of the total regional population, is projected to live in urban centres (1). For governments, investors, and innovators, this urban boom signals unprecedented opportunity.

Yet, beneath the gleaming skylines lies a sobering reality. The same growth that drives prosperity is also eroding its foundation. Farmland is disappearing at a pace that threatens food security and livelihoods, as in Vietnam where agricultural land and crop production are projected to shrink by 10.3% and 15.9% respectively by 2030 (1). Waste mountains are rising, with Southeast Asia accounting for 20% of global waste production (2) and landfills like Semakau in Singapore expecting to reach its limits by 2035 (3).  Climate extremes across the region from typhoons in the Philippines (4) and Vietnam (5) to record-breaking heatwaves in Indonesia, Thailand and Myanmar (6), are no longer anomalies but recurring disruptions. Without intervention, these converging crises threaten to undo the very gains that urbanization has created.

The question is not whether Southeast Asia can continue to grow, but whether it can do so sustainably. This is where environmental biotechnology becomes more than a scientific discipline but a strategic imperative. By harnessing microbes, plants, enzymes, and bio-based processes, biotechnology can help reimagine food systems, transform waste into resources, and restore polluted ecosystems, turning urgent environmental challenges into engines of resilience and opportunity.

 

Opportunity areas

Climate-resilient agriculture

Southeast Asia’s farmland is shrinking under the pressure of urban expansion, while erratic weather threatens the productivity of what remains. Rice, the region’s staple, is especially vulnerable, with every 1°C increase in temperature cutting yields by up to 10% (7). To safeguard food security, agriculture must be reimagined for resilience. Environmental biotechnology offers pathways to sustain production while reducing vulnerability to climate shocks.

Gene editing offers a powerful tool. By making precise modifications to plant genomes without introducing foreign DNA, high-yielding, drought- and disease-resistant crops, or even varieties with enhanced nutritional content can be developed. Countries such as Thailand, Indonesia (8), and Vietnam (9) are not only building legal frameworks but also actively encouraging the use of this technology. This is a promising signal that the region is preparing to harness biotechnology for food security.

Cellular agriculture, meanwhile, decouples food production from land and weather altogether. From cultivated meat and milk to coffee and chocolate, the field is gaining traction across the region. While cost and accessibility remain significant hurdles, recent developments suggest startups are tackling these challenges head-on. The Singapore start-up Prefer, for instance, uses precision fermentation to transform day-old bread and soybean pulp into coffee beverages (10), simultaneously addressing food demand and waste reduction. This dual benefit underscores how agricultural biotechnology can be aligned with broader sustainability goals, including waste management, setting the stage for the next opportunity area.

 

Waste management and circular economy

Southeast Asia’s rapid urbanization has fueled unprecedented consumption and waste generation. Food (11) and plastic (2) wastes dominate the landscape, while e-waste is surging with rising digital adoption and short device lifespans. Over 3.9 million tons of e-waste are produced annually in the region, yet formal recycling systems remain limited (12). Current solutions, heavily reliant on landfills and incineration, generate new risks: methane emissions, ocean leakage of plastics, and toxic chemical leaching. These challenges are exacerbated by poorly managed waste infrastructure, particularly in rural and peri-urban areas.

Yet waste is not just an environmental liability but an untapped backbone of sustainable development (13). Indonesia, producing over 14.7 million tons of food waste annually, has seen innovative responses such as Magalarva, a social enterprise using black soldier fly larvae to convert food waste into high-quality animal feed (14). Similarly, researchers in Singapore are exploring the potential of gut bacteria in “superworms” (Zophobas atratus) to digest plastic (15), alongside enzymes that can break down polyethylene terephthalate (PET) into its building blocks for remanufacture or upcycling (16). Research groups in Singapore (17) and Malaysia (18) are also piloting the use of microbes to extract valuable metals such as lithium, nickel and copper from discarded lithium-ion batteries and circuit boards. Though not yet scalable, these innovations hint at a future where food, plastic, and electronic waste can be converted into critical resources, turning liabilities into economic and ecological opportunities.

 

Pollution mitigation and ecosystem recovery

The stench of garbage-choked rivers or the sight of coastlines darkened by oil slicks are stark reminders of how human activity degrades our environment. Pollution disrupts daily life, harms health, and threatens economies dependent on natural resources. Environmental biotechnology offers ways to reverse this damage.

Take Tonle Sap, Southeast Asia’s largest freshwater lake as an example. It is increasingly contaminated by agricultural runoff and untreated waste, which residents rely on for drinking, cooking, and bathing. These unsafe waters drive outbreaks of diarrhoea, killing more than 380 children every year (19). Solutions such as HandyPod, a decentralized sanitation system, demonstrate how the use of microbes can purify and remove pathogens from wastewater and protect public health (20). While effective, the system remains costly, limiting its adoption in many rural communities.

 

Similarly, crude oil spills, like the one off Rayong province in Thailand, highlighted the vulnerability of marine ecosystems and economies reliant on tourism. Researchers are developing “oil-eating” microbes that can break down oil pollutants and other toxic residues (21), offering a natural, less intrusive way to restore ecosystems. If scaled, such innovations could form the foundation of a regional toolkit for pollution response and ecological recovery.

 

Challenges

Southeast Asia’s diversity in development and urbanization complicates the implementation of environmental biotechnology. The region experiences vastly different degrees of urbanisation, ranging from 100% in Singapore to around 26% in Cambodia in 2024 (22). This disparity underscores the need for solutions that are tailored to local conditions, infrastructure, and socio-economic realities.

Many environmental biotechnology solutions remain in the research or pilot stages, requiring significant investment, regulatory support and time commitment to achieve impact at scale. Yet, funding for biotechnology has historically been concentrated in healthcare and pharmaceuticals, leaving climate and environmental applications relatively under-resourced. Encouragingly, philanthropic organizations like the Gates Foundation have earmarked areas such as agriculture and sanitation for funding, and other sustainability-focused funding streams are also emerging. Environmental biotechnology could strategically position itself to tap into these resources, but this requires greater visibility and prioritization.

Governments also face the delicate task of balancing environmental sustainability with economic imperatives. For countries still working to industrialize or lift populations out of poverty, environmental goals cannot come at the expense of livelihoods and growth. This makes it essential to frame innovation not as a luxury but as a tool for sustainable development — one that enhances resilience, creates green jobs, and drives inclusive growth. The ASEAN’s Plan of Action on Science, Technology, and Innovation 2026–2035 (23) signals positive momentum, but the region must ensure that environmental biotechnology is not sidelined in this process.

Finally, equity must remain central. If solutions are designed only for urban centers or wealthier populations, they risk deepening existing inequalities. Rural communities, informal settlements, and vulnerable groups often face the greatest environmental risks yet have the least access to technological solutions. For environmental biotechnology to fulfil its promise, it must deliver benefits across society and ensure that no community is left behind in the transition toward sustainability.

 

Conclusion

Southeast Asia faces a pivotal choice: allowing rising waste, pollution, and climate pressures to dictate its future, or harness environmental biotechnology to transform these challenges into engines of growth, resilience, and innovation. Climate-resilient agriculture, waste-to-resource systems, and pollution mitigation represent immediate, actionable opportunities to reshape the region’s development trajectory. Will the region be able to leverage science, policy, and collaboration to act decisively before this window closes?
