When it comes to coffee habits, switching to a reusable mug can make a big impact. Many Americans grab coffee on the go, and disposable cups and lids add up quickly. A travel mug that fits in your car cup holder can reduce waste and may even earn discounts at some coffee shops. If you brew at home, consider using a reusable coffee filter instead of disposable paper ones. This is a small shift that reduces waste without changing the flavor of your morning routine.
