Green technology or greentech innovations are playing a crucial role in waste management in Southeast Asia. As the region’s urban population grows, so does the need for effective and sustainable solutions for managing waste. Greentech uses science and technology to create environmentally friendly products and services. It aims to reduce the negative impact of human activity on the environment and promote sustainability. Waste management is one of the areas where it is making a significant impact. 

As savvy investors also consider the industry’s impact on the environment, many are choosing to put their money into companies that focus on sustainability and corporate responsibility. This move towards cleaner and more effective waste management is becoming a hot topic. As pressure mounts on countries to clean up their acts, many governments also support schemes and startups working in the clean tech sector.

Tech solutions to waste

As companies strive to be more energy efficient and environmentally conscious, many seek innovative solutions to aid their progress. This has led to an uptick in startups developing technology to assist in the battle against wastage and the disposal of byproducts of manufacturing and life in general. 

Some emerging sectors are:

Waste-to-energy technologies

Governments across Southeast Asia are eager to tap into Waste-to-energy (WTE) technologies to address the region’s rapidly increasing waste generation. These technologies convert waste into energy to power homes and businesses. In 2023, the industry is worth approximately USD 3,326 million, but predictions show it almost doubling to USD 6,070.97 million by 2028. Malaysia has recently invested in one such project.

However, it is not the perfect solution to the lack of energy and waste disposal. There are concerns about the environmental impact of these incinerators and the need to balance the correct calorific value and quality of the waste to optimise both disposal volumes and electric sales.

Biomass and hydropower

ASEAN countries are also embracing renewable energy sources like biomass and hydropower. Biomass, derived from agriculture and forestry waste, has massive potential in countries such as Vietnam, where a robust agrarian culture already exists. 

Laos has a plentiful supply of renewable energy, with a biomass supply of approximately 46 million tonnes per year. 

Several other green startups in the region are developing innovative solutions to counteract the damage of industrial, agricultural and household waste. One such innovation is from Hi-Gi Energy in the Philippines. It changes a commonly found plant, the water hyacinth, into compressed blocks of coal dust known as briquets. In a country where many still use firewood or charcoal, this green, alternative cooking fuel can play a vital role in reducing deforestation and air pollution.

Recycling innovations and circular economy practice

Recycling is an essential part of waste management, and green technology is making it more efficient and effective. Startups like Sustaintech have developed reverse vending machines for PET plastic bottles and aluminium cans, incorporating AI and IoT technology to improve community recycling rates in Thailand. 

REBOON is another company focussing on establishing waste separation and recycling centres within community temples in Thailand, leveraging the temple’s central role within the community as a spiritual and educational hub to raise awareness on environmental and waste issues. 

Waste4Change in Indonesia is a green startup that provides waste services, including recycling, composting, and waste-to-energy solutions, with most countries having similar innovative companies.

IoT and data-driven waste management systems

The use of IoT and data-driven waste management systems to optimise waste collection and disposal is a growing trend. Such systems use sensors and data analytics to monitor waste levels and predict when bins need emptying. 

The data collected reduces the number of collection trips required, saving time and money while reducing carbon emissions. Singapore’s Green Nudge uses IoT technology to optimise waste collection in the island nation.

Lessons from China and the scope of waste management

As Southeast Asian countries embrace technology for waste management, they must learn from China’s rapid adoption of waste-to-energy. It has the most waste-to-energy capacity globally but is more comparable to other emerging economies, as its waste tends to be “wet” and of low caloric value for burning. 

Southeast Asian countries can learn from China’s experience utilising wastewater and other organic matter to produce biogas and developing waste incineration plants as a waste management solution, with energy as a co-benefit. 

Greentech innovations in Southeast Asia must overcome some challenges, including high upfront investments and a lack of technical expertise. However, opportunities exist to create jobs and economic benefits, reduce reliance on landfills, and promote sustainability. By investing in green technology, supporting government policies, and taking practical steps to reduce the environmental footprint, the region’s countries can all contribute to a more sustainable world and help preserve the planet for future generations.

Green technology is playing a crucial role regionally. Waste-to-energy technologies, recycling innovations, circular economy practices, IoT and data-driven waste management systems are some of the most promising solutions for a greener future.
