Once dubbed "garbage island" for its overflowing landfills and filthy streets, Taiwan now has Asia's highest rate of recycling and is a role model for the region, analysts said on Thursday.

With untreated waste causing marine pollution and clogged drains triggering fatal floods from Bangkok to Manila, Southeast Asian cities should look to Taiwan's success in reducing and recycling waste, they said.

"Taiwan didn't do anything mystical; it just developed good policy based on the experiences of others," said Nate Maynard at Taiwan's Chung-Hua Institution for Economic Research.
