Consider making a habit of making your own lunch, rather than relying on takeout food supplied with single use packaging and utensils. A good quality lunch cooler like this one from Kooshty will make it a lot easier. The bonus is that it’s made using RPET fabric, which is a material made from recycled single-use plastic bottles.
