QUESTION: Can I compost junk mail?
ANSWER: Yes you can, and yes you should! Instead of sending all of your paper trash to the landfill, invest in a nice paper shredder and start turning your junk mail and other paper waste into garden gold. Small, inexpensive shredders are usually more trouble than they are worth, as they fill up too quickly and tend to jam or break often.
For around $150, however, you can get a large volume, high-quality shredder for your home office and composting needs. Adding paper waste to your composting efforts is a great way to increase the amount of compost you create, plus, decomposed paper is a carbon-rich material that gives a nutrient boost to your finished compost.
