No matter what you buy, chances are most things can be made from post-consumer recycled or recyclable material. Post-consumer' refers to products previously bought, used and recycled. Buying such products also encourages manufacturers to use recyclable materials. Second-hand items can also help conserve your bank account and the environment. You can barter for pens, pencils, rulers, compasses, binders and text books.
Packaging is also something to think about when making school lunches.
Aim for a litterless lunch. Reusable, plastic containers eliminate the need for plastic wrap and keep your food from getting crushed. And by using your own refillable containers, you can buy food in bulk instead of purchasing the more expensive one-serving sizes. Finally, pack the whole lot in a reusable lunch box or cloth bag instead of a disposable paper bag. There's no better place to learn about the environment than in school.
