Toting your own to-go mug or reusable water bottle isn’t just an eco-altruistic act. You can reap some real selfish benefits by becoming a reusenik:

1. Extra money. Whether it’s a nearby Starbucks or an indie coffee shop, many coffee shops offer you between a nickel and dime off your drink for BYOing. Urth Caffe offers you a full quarter off!
2. Fewer injuries. Never burn yourself fiddling with those those flimsy plastic coffee cup covers again! Reusable travel mugs and bottles generally come with spill-proof lids, preventing such unfortunate owies.
3. More style. Show off your uniqueness by carrying a mug that reflects your personal style — whether that’s a sport top bottle or a sleek stainless steel mug. Also, you won’t get coffee stains on your outfit due to ill-fitting disposable cup lids.
4. Prettier neighborhood. Raise your property values by reducing the sidewalk trash! Those overflowing trash bins outside every Starbucks — not to mention the disposable cups jettisoned into flower beds and sidewalk gutters — are an eyesore we can easily prevent.
5. Better health. According to the Natural Resources Defense Council, “Studies have shown that chemicals called phthalates, which are known to disrupt testosterone and other hormones, can leach into bottled water over time. One study found that water that had been stored for 10 weeks in plastic and in glass bottles contained phthalates, suggesting that the chemicals could be coming from the plastic cap or liner.” Don’t become a statistic — Free yourself from disposable plastics!
Of course the environmental impacts too are still important and meaningful. GreenBiz reports that “Three billion of the world’s 200 billion-plus paper cups that start as trees and end up at the dump each year bear the Starbucks logo,” for example. Even if these cups are made with paper, they’re not easily recyclable, as coffee-stained paper shouldn’t be put into your recycling bin. Styrofoam (aka polystyrene) cups are even more monstrous, harming marine life, clogging up our waterways, and costing taxpayers way too much to recycle — which explains why they’re illegal in Santa Monica and should be everywhere else too. Besides, recycling comes in dead last in the reduce, reuse, recycle list. BYOing is the way to go.
I have a small arsenal of to-go mugs and bottles (above), all of which, luckily enough, I got free. I’ve got 2 mugs — a stainless steel Bring Your Own mug that’s my main totable, and a plastic Equal Exchange mug that serves as a spare. In general, stainless steel is better, both in terms of health and simple style. As Umbra of Grist points out, plastic mugs get dingy more quickly: “Stainless, on the other hand, will hold the sleek, successful lawyer look over time.”
My Equal Exchange cup’s a relatively safe #5 plastic, but because there’s so much we still don’t know about plastics, I much prefer the stainless steel. For water, I have both a big BPA-free FilterForGood Nalgene bottle and a smaller Sigg aluminum bottle.
So start bringing your own! And if you forget once in a blue moon — Don’t despair. Just take that as a sign to sit down to enjoy your cup of coffee in the coffee shop in a ceramic mug. Want to take your BYOing habit a step further? Take your own glass to parties and start a trend! LA Green Drinks even encourages enviro-winos to tote their own glasses.

Nice to see you still have your BYO mug! I’ll have to give you a few produce bags, now that I’m back from my ride and getting back to byo….Cheers

Speaking of what we don’t know about plastics, what we don’t know is a lot. Because while the polymer itself might be relatively inert (polyethylene, for example, or polypropylene), it’s the mystery additives that are responsible for so much trouble. And those additives are never disclosed on labels.
This is my rant of the month. We insist that food labels disclose all the ingredients in the food, and we want dairy companies to be able to let us know if their products contain rBHT. But we have no idea what chemicals have been added to the plastic in which those products have been packaged — chemicals that could be leaching hormone disruptors back into our food!
I really feel a campaign coming on, but I have no idea how to proceed with it yet. I think that packaging should be part of organic certification. And I think the ingredients in plastic packaging should be disclosed like food ingredients are. It’s a huge issue and bigger than me. But I think it’s really important.
(I’ve even heard recently that some companies add chemicals to their plastic packaging specifically so they don’t have to list them in the ingredients. Like preservatives for cereal, for example.)
Anyway, this has nothing to do with reusable mugs and water bottles, but your comment about plastic just got me started up again.
Totally agree with you about stainless steel!

I love my Klean Kanteen bottle for my water! I think that I am going to buy one each for my parents so they always have one. I bought one for each of my staff members last Christmas, and they seemed to really appreciate them.
I also need to find a good reusable mug for my dad to drink his coffee. I think they use styrofoam cups at his work, eek!

With office mugs you don’t even need to worry about portability — Get him a cute one he’ll reuse just to show off :)
