Sansiri, a leading Thai property developer, has successfully converted 50,000 plastic bottle caps (206 kg) from residents into a durable, safe children's playground across three pioneering projects in the Ratchaphruek area. The "Waste to WORTH" campaign demonstrates circular economy principles in action, reducing plastic waste by 61 kg and preventing 117 kg CO₂e emissions. This marks the first eco-friendly playground in Thailand's real estate sector, developed through a partnership with four green ecosystem partners including logistics provider WasteBuy Delivery and recycling platform GC YOU Turn.
