From The Daily Green:
Being thrifty in the kitchen, just like grandma used to, will cut down on the amount of waste you produce. Nobody expects you to make a pie every day like she did, but taking a few pointers will help you be as green as possible.
Use up leftovers. Try incorporating them into new recipes instead of letting them sit in the fridge. Leftovers today are opportunities for tomorrow.
Cook instead of going to restaurants or ordering take-out. You’ll save money cooking for yourself, and you’ll avoid the waste from extra take-out packaging.
Don’t just cook. Cook from scratch. Whole, natural ingredients are better for you. Avoid the pre-packaged stuff, and you’ll avoid preservatives, additives and the wasted packaging material.
Be thrifty. But don’t be thrifty by buying cheap stuff. Try to pick things (like appliances and furniture) that are durable and will last you a long time. You’ll go through less stuff, and less will be sent to the dump. It’s a win-win!
