A new law bans popular plastic bags in the Mexican capital, and grocery stores are poised to sell reusable synthetic fiber bags. The same law will ban handing out plastic straws, spoons, coffee capsules and other single-use items by 2021. Claudia Hernández, the city’s director of environmental awareness, says, “We are finding that people are returning to baskets, to cucuruchos [cone-shaped rolls of paper].” The old ways are present in other aspects, too. Many residents still use wheeled, folding shopping baskets and some vendors still measure out bulk goods in discarded sardine cans. Grocery stores that give out plastic bags will be fined, so most will opt for reusable shopping bags made of thick plastic fiber for about 75 cents. For hygienic reasons, the law leaves the door open to using plastic bags for such items as perishable deli meats or cheese.
