Precycling is trying to reduce waste by "pre-thinking" our purchases.
While recycling is, of course, a positive thing, it still requires energy to transport the materials, melt them down and then re-manufacture items. Precycling tries to avoid the amount of stuff that gets chucked into landfills AND the recycling bin to begin with. Here are some tips:
Buy in bulk, avoid individually wrapped items.
Buy items that come in recyclable packaging instead of non-recyclable.
Avoid junk mail.
Use a computer instead of reading "real" magazines and newspapers.
Bring your own utensils with you instead of using plastic ones.
Use cloth handkerchiefs and napkins. And of course, reduce and reuse as much as you can, first!
