Make a zero waste kit
For when you are out and about, it’s a good idea to bring a zero waste kit with you for when you need to grab something to eat. Now, there are a ton of zero waste kits for sale online but it’s super simple to put your own together. Here are the things you need: cloth napkin, reusable cutlery (these can just be the regular metal cutlery you use at home), reusable container (any container will do but the collapsible kind does takes up less space in your bag), a reusable water bottle, a reusable coffee mug, and a metal straw (if you ever buy smoothies or prefer straws at restaurants, etc). You can keep those items wrapped in a reusable cloth bag in your purse or backpack and you are all set.
