Building a Better Water Bottle: Aluminum, Steel, and No BPA
by Alicia MacLeay
February 1, 2008
Backpackers, hikers, and climbers have always relied on reusable water bottles. As the general public becomes more aware of the negative environmental impacts of
commercial bottled water (see “The Bottled Water Problem”
below) they’re turning to reusable bottles too.
But,
with health concerns about some plastics making the news, many are left
confused. In what should you store your filtered or tap water? And is that
old polycarbonate plastic bottle safe, or is it leaching chemical
compounds?
(see “What’s the Deal with BPA?” below)
Whether it’s for a trek into the backcountry or a trip to the store, there are a growing number of aluminum, stainless steel, and BPA-free plastic alternatives to choose from, beyond the popular, but potentially problematic, polycarbonate water bottle.
The Bottled Water Problem
Still drinking bottled water when you could safely filter or turn on a tap? Consider:
- 1.5 million barrels of oil are used to make water bottles in the U.S. each year.
- Bottled water also requires oil for shipping, refrigerating, and even recycling.
- 86% of plastic bottles in the U.S. end up in a landfill or incinerator.
- More than 60 million plastic bottles end up in landfills and incinerators every day — 22 billion a year.
- Water quality standards set by the EPA for tap water are more stringent than the FDA’s standards for bottled water.
- Ounce for ounce, bottled water costs more than gasoline.

Aluminum
SIGG
At 100 years old, the stylish Swiss company is coming off its strongest year ever in the United States. SIGG
bottles, made from a single piece of aluminum (no leaks), have a
water-based, non-toxic interior coating. The liner’s finish helps
protect from bacteria and mold and is neutral and resistant to fruit
acids and energy drinks (so drinks taste like they should). SIGG
bottles have been independently tested to prove they are completely
leach-free and are 100 percent recyclable.

Simply Eco-Logical
SIGG lifestyle bottles come in a range of sizes (0.3, 0.6, 1.0 liter,
and more) and lids (screw top, active, sport, kids). And new designs
are offered seasonally. For 2008 choose a 1-liter Eco-Logical bottle
and send a message like “Friends don’t let friends drink from plastic”
on the back. Capacity: 1 liter (33.8 oz)
Weight: 5.2 oz
MSRP: $21.99 |
Stainless Steel
Guyot Designs and Nalgene
Guyot Designs’
stainless steel, wide mouth bottles are the only ones that work with
standard 63 mm water purifiers and accessories. Through May 2008, the
unlined, single wall bottles are available only through Guyot. After
that they’ll be co-branded with Nalgene, so expect wider availability soon.
As
part of their C-Minus program, every Guyot bottle comes with more than
enough greenhouse gas offsets to offset the negative impact of their
manufacture (100 lbs of verified greenhouse emissions). And, like all
stainless steel bottles, they’re 100 percent recyclable.
Klean Kanteen
Since 2004, Klean Kanteen
has produced unlined, stainless steel bottles in children’s (12 ounce)
sizes up to 40 ounces. Bottles come with a range of cap options (sport,
flat, loop, sippy for the small set) and are clean tasting, dishwasher
friendly, and 100 percent recyclable. Klean Kanteen’s first colored
bottles will debut in late spring of 2008.
SIGG
SIGG’s signature item is its aluminum lifestyle bottle, but the company also offers stainless steel thermoses, vacuum-insulated mugs, and, new for 2008, a thermal bottle and a vintage oval bottle.

Hot & Cool
The double wall Hot & Cool has a classic SIGG shape, but with thermal properties to keep drinks at the right temperature. Capacity: 0.5 liters (17 oz)
Weight: 11.7 oz
MSRP: $27.99 |
 | Vintage Oval
The designer Vintage Oval bottle has a smooth hand feel and a leak-proof, retro swing top.
Capacity: 0.4 liters (13.5 oz)
Weight: 5.8 oz
MSRP: $27.99

BPA-Free Plastic
CamelBak
CamelBak’s Performance and Podium Bike bottles are, and always have been, BPA- and phthalate-free. By summer 2008 all CamelBak bottles, including new Better Bottles and Classic Cap Bottles, will be BPA- and phthalate-free.
What’s the Deal with BPA?
Due to health concerns about infertility and cancer, Canada’s Mountain Equipment Co-Op (MEC) pulled most products
containing bisphenol-A (BPA) in December. Vancouver yoga
retailer Lululemon Athletica followed suit. Patagonia pulled polycarbonate products from its
retail stores back in 2005.
Bisphenol-A (BPA), found in polycarbonate plastics (#7/other, sometimes called Lexan), is an endocrine disruptor that has
been shown to affect reproduction and brain development in animal studies. it can
leach into foods and liquids and mimics estrogen when absorbed by the
human body.
Think new polycarbonate bottles are okay? A
recent study by University of Cincinnati scientists showed that liquid
temperature, not a container’s age, has the most impact on how much BPA
is released. When the same new and used polycarbonate drinking bottles
were exposed to boiling hot water, BPA was released 55 times more
rapidly than before exposure to hot water. (Toxicology Letters)
Phthalates are used as
plastic softeners or solvents. They are believed to cause damage to the reproductive system and increase the
risks of allergies, asthma, and cancer. They’re banned from toys and childcare items in Europe.

Better Bottles
CamelBak switched its 2008 Better Bottle line to
Eastman Tritan
copolyester, a new bisphenol-A (BPA)- and phthalate-free material. BPA-free bottles started
shipping to retailers in January of 2008, and all Better Bottles will be
BPA/phthalate-free by the end of spring. In the mean time, look for a
BPA free-logo on the bottle’s side. 0.5 Liter
Weight: 5.4 oz ($10) 0.75 Liter
Weight: 6.6 oz ($12) 1 Liter
Weight: 7.4 oz ($14)

Classic Cap
New
for 2008, the Classic Cap Bottle is made from
the same temperature- and impact-resistant, BPA- and phthalate-free
Tritan material as the Better Bottles. 0.5 Liter
Weight: 5.4 oz ($10) 0.75 Liter
Weight: 6.6 oz ($12) 1 Liter
Weight: 7.4 oz ($14) |
Nalgene
Nalgene
is practically synonymous with the polycarbonate water bottle. While
those ubiquitous, bright-colored, plastic bottles are now coming under
fire (see
“What's the Deal with BPA?”
above), the company isn’t dropping its popular line, yet. However, it
is offering consumers more options, including different plastics and Nalgene-branded versions of Guyot Designs’
stainless steel bottles (see above).
|
HDPE Bottles
Nalgene
makes several versions of its classic water bottle in softer, HDPE
(#2) plastic. HDPE, high density polyethylene, is non-leaching and
considered safe for food and drink containers. A new,
full line of HDPE bottles, in a range of colors, will be available
starting February 21, 2008. The HDPE bottles come in 12- to 48-ounce
sizes, with narrow or wide mouths, and loop tops.
Capacities: 12, 16, 32, and 48 oz
Weight Range: 3.68 oz to 5.28 oz
MSRP’s: $5 to $10 |
|
Everyday Line
Made with the new temperature- and impact-resistant Eastman Tritan copolyester (like CamelBak’s Better and Classic Cap bottles
above), the Everyday Line will launch in March 2008 with BPA- and phthalate-free versions of Nalgene’s 32 oz Wide Mouth bottle, On-the-Go bottles, and kids Grip-n-Gulps. |
GSI Outdoors
GSI Outdoors reportedly is working on a BPA-free water bottle and aims to eliminate BPA across its product line by 2009. GSI already offers stainless steel vacuum bottles, mugs, and flasks.
