2) Compost- in a house, in condo, in a apt, you can do it, and use the soil to plant your own home herb garden! Eartheasy has a terrific site to show you how to get started, or what do do next!
3) Use homemade household cleaners like vinegar and baking soda to make these great cleaners:
All-purpose cleaner
Fill a spray bottle halfway with vinegar and top it off with plain water. Add lemon juice or another pleasant-smelling essential oil to hide the vinegar smell. Shake it up and use as every day household cleaner.
Glass surface cleaner
Fill a spray bottle a quarter way with vinegar and top off with warm water. For a faster-drying alternative, pour 1 cup rubbing alcohol, 1 cup water and 1 tablespoon vinegar into a spray bottle. The rubbing alcohol evaporates quickly, and acts as a good rival for commercial glass cleaners.
Floor cleaner
Fill a bucket with 1 gallon hot water, 1 cup vinegar, and a few drops of tea tree oil. For tough jobs, add 1/4 cup borax or baking soda and 1/2 cup ammonia. For marble or granite floors substitute rubbing alcohol for vinegar or ammonia. This will protect the porous surface from the harsh acidic qualities of the vinegar and ammonia.
Furniture polish
In an old olive oil bottle, mix 1 cup olive oil and 1/2 part lemon juice. Pour the oil onto soft cloth and gently rub into the furniture. This is best for real wood surfaces, but works on faux wood and plastic, as well.
