Is there anywhere where you can take papers to be shredded?
A friend of mine puts all of her shreddable, non-glossy papers in a big bucket and fills it with water, then drains the water after a couple of days. She shapes the mush into big balls (bigger than softballs) and uses them as fire starters for her wood stove or outdoor campfires.
Is that cool or what? Her 4 year old loves being the ball thrower!
Also, probably just about any bank. When I worked as a teller we had to shred *everything* because so much of what we handled was confidential. We were a teeny tiny branch and had two big locked mega trash bins that a service came and took once a week. We didn't advertise is as a service, but we never turned anyone down who asked us to shred old checks or whatever. A whole garbage bag probably wouldn't fly because we fill up those bins, but a grocery bag wouldn't have been a big deal.
OfficeMax does too. Shredit the company has shredding days where they park a big truck and you can bring your stuff. Staple and OfficeDepot and OfficeMax have bins that they put your stuff in that they cannot get into and then a shredding company comes and destroys it. The only issue with this is that sometimes with large volumes they dont have a lot of room so call the stores and ask how many bins they have open. One bin will usually hold 4 paper boxes full of paper.
The ups store has a huge self serve shredder. But this costs around three times as much as the bin service.
You can also have them come stop by your house and shred it on site for you.
Whats nice about the bins at omax, officedepo or staples is that they can shred anything up to the thickness of a wall nail. So binder clips paper clips and staples and all stay on the documentation.
