Two small wins for Hawaii residents — easier composting and fresher school food — plus a Diet Coke squeeze annoying shoppers on the mainland and here.

• Starting October 1, Honolulu's G.R.O.W. program goes island-wide on Oahu, so food scraps can go in the green cart with yard waste.
• The rule is simple: if it grows, it goes — fruit, vegetables, meat, bones, coffee grounds, eggshells, bread, even spoiled leftovers. No plastic, glass, metal, or so-called compostable bags and utensils.
• Diverting scraps could cut Oahu's trash by up to 20%. To keep the cart from stinking, freeze scraps until pickup night, bury them under yard waste, and use baking soda or peppermint, rosemary, and eucalyptus oil to keep rats and roaches away.
• Hawaii's Department of Education is now serving locally grown pineapple, with 2,100 pounds sent to 21 Oahu schools and more joining — as a side or in a new island-style chicken wrap.
• Diet Coke cans are hard to find in some stores, though the brand is still one of Coca-Cola's billion-dollar sellers with global sales up 7% last quarter. Frustrated shoppers can pay up to $95 for a rage retreat session, a trend spreading out of Chicago that therapists say is no substitute for real therapy.

Outlook: More Oahu households start composting curbside in October, and more schools should get local pineapple as the state keeps buying from Hawaii farmers.
