The World's Shortest Comprehensive Recycling Guide

Good Bad Notes
Unbroken glass containers
(clear glass is the most valuable).
Tableware, ceramics, pyrex, windows, lightbulbs, mirrors. Only bottle glass is acceptable. Ceramics contaminate glass. Mixed color glass is near worthless, and broken glass is hard to sort.
Clean dry newspapers &
newspaper inserts.
Rubber bands, plastic bags, product samples, water, dirt, mold or other contamination. Pack newspapers tightly in large brown grocery sacks or tie with natural twine. Protect from rain and snow.
Empty metal cans, caps, lids, bands and foil. Full cans, spray cans unless instructed, cans with paint or hazardous waste. Metals can be recycled again and again.
Plastic stamped #1 or #2 on the bottom. Some areas only accept clear plastic or certain shapes. Plastic types #3, #4, #5, #6 or especially #7. Caps are usually a different type from the bottle - toss if unmarked. Even a small amount of the wrong type of plastic can ruin a melt. Much plastic collected for recycling is actually landfilled or wasted.
Plastic bags marked #2 or #4. Unmarked plastic bags. Many grocery stores take bags.
Mixed paper: junk mail, magazines, photocopies, computer printouts, cereal/shoe boxes, etc. (some places also take corrugated cardboard and phone books). Stickers, napkins, tissues, waxed paper, milk cartons, carbon paper, laminated paper (fast food wraps, some food bags, drink boxes, foil), neon paper, thermal fax paper. Any wet or food stained paper. When in doubt, throw it out.

Paper fiber can be recycled about 7 times before it gets too small. Plastic window envelopes are ok in many areas.
Scrap aluminum such as lawn chairs, window frames and pots. Non-metal parts and metal parts attracted to magnets. Aluminum is not attracted to magnets.
There is no need to remove labels or bands from cans and bottles. Clean only enough to prevent odors. Do not recycle containers with traces of hazardous materials. Do not recycle dirty or food stained paper.
Motor oil (never dump into storm drains). Call your garbage company, local quick-lube or 1-800-MOTOROIL. Each year do-it-yourselfers improperly dump more oil than the Exxon Valdez spilled.
Automotive batteries, sealed lead/gel-cell batteries. Keep lead out of the environment; take to an automotive or security dealer for recycling or trade in.
Rechargeable Batteries (cordless phone, camcorder, shaver, portable appliance, portable computer, etc.) Call 1-800-8BATTERY for information. Throw alkaline and heavy duty batteries in trash unless prohibited. Nickel-Cadmium rechargeable batteries contain toxins, please recycle.
Laser/Ink printer cartridges. Send to one of the many recyclers or refillers.
Household toxics (paints, oils, solvents, pesticides, cleaners) Call your garbage company for advice. Do not dump into storm drains.
Computers, eyeglasses, household goods. Donate to charity.
