Last week’s mail stacking up on the kitchen counter? Recycling mailing materials and envelopes is easier than you think! You can remove the plastic window in envelopes that have them, but you don’t have to. Those get removed or sorted out at most recycling facilities. Leave stamps on the envelopes, unless you happen to be a collector! Flyers, magazines, newsletters and paper mail of all shapes and sizes can go straight in the bin. Glossy, colored, or plain, throw it right in.
