The Bangkok Metropolitan Administration (BMA) and the Thai-Danish network have launched a significant pilot project aimed at reforming waste management in high-rise residential buildings (condominiums). The initiative, spanning the Khlong Toei and Watthana districts, aligns with the city’s “Mai Te Ruam” (No Mixing) policy to create an efficient sorting model. The project is designed to prepare residents for upcoming “polluter pays” waste collection fees while addressing Bangkok’s daily 9,000-tonne waste crisis.
The capital currently faces an immense logistical and financial burden: approximately 9,000 tonnes of municipal waste are generated daily, more than 50% of which is organic food waste. Pornphrom Vikitsreth, advisor to the Governor of Bangkok on environmental affairs, emphasized that separating waste at the source is essential for reducing management costs and ensuring sustainable urban operations.
District Focus and Statistical Data: What’s Inside the Bins?
The pilot project was launched across ten selected condominiums in the Khlong Toei and Watthana districts. A field survey conducted by the Thailand Environment Institute (TEI) shed light on the exact composition of waste generated in high-rise buildings, providing a baseline for the system’s refinement:
-
General (Mixed) Waste: 41% (the largest share)
-
Food Waste: 35%
-
Recyclable Materials: 21%
-
Hazardous Waste: 3%
The research also identified the five most common items found in general waste bins: food scraps, contaminated paper, single-use plastics, recyclable plastics, and glass. These insights are helping the BMA optimize educational messaging and the placement of collection bins to prevent cross-contamination.
The “Polluter Pays” Principle: Economic Incentives on the Horizon
A primary goal of the pilot project is to prepare residential communities for the implementation of the “New Regulation on Fees for the Management of Municipal Solid Waste and Wastewater (BE 2568 / 2025).” This legislation is based on the Polluter Pays Principle and utilizes economic incentives to encourage sorting:
-
Lower Fees: Households and condominiums that can demonstrate they effectively separate their waste will be eligible for a discounted tariff.
-
Higher Fees: Those who continue to dispose of waste in a mixed fashion will face significantly higher waste management costs.
Pornphrom Vikitsreth noted that the project fills a market gap where residents are willing to sort, but high-rise internal systems—such as trash chutes or centralized storage areas—currently do not support efficient separation.
The Danish Connection: Simplicity and Pictograms
The Thai-Danish network and the Embassy of Denmark in Thailand play a pivotal role in the project’s execution. Danny Annan, the Danish Ambassador to Thailand, pointed out at the launch that in Denmark, household waste is separated into up to 10 different categories, allowing for the recycling of nearly half of all waste.
Key lessons from the Danish model being adapted for Bangkok include:
-
Simplicity: Utilizing clear, visual signals and pictograms instead of complex written rules.
-
Corporate Collaboration: The network brings together Danish giants such as Pandora, Grundfos, and Danfoss, providing technical expertise in localizing circular economy models.
-
Danish Environmental Protection Agency (DEPA): Represented by Jens Nytoft Rasmussen, the agency provides technical know-how to refine the logistics of the collection systems.
Future Outlook and Scaling
The BMA is closely monitoring the results of the pilot project in Khlong Toei and Watthana. Following a successful trial period, the administration intends to scale the model across all 50 districts of Bangkok. The ultimate goal is to create an integrated system where high-rise properties handle waste separation from the design or operational phase, meeting the expectations of the “no mixing” policy and laying the groundwork for a cleaner, more economically sustainable metropolis.
