The Environmental Cost of a Free Canvas Bag

When it comes to the environment, free canvas bags aren’t free

  • Cool Tote's Environmental Impact

It’s difficult  to pinpoint when the canvas tote craze really started. The concept isn’t new, of course. Public television stations have been giving them away during fundraisers for decades, and L.L. Bean’s “Boat and Tote” has been a New England staple even longer. Sometime during the past few years, how­ever, the environmental appeal of reusable bags and the easy application of graphics catapulted canvas sacks from health food stores to the runway.

Graphic designers embraced the form as a venue for messages on a par with the T-shirt. Design blogs became enthralled by the never-ending stream of totes—each one made unique by a clever or beautiful graphic. This glut of bags raises questions about the sustainability of any product regardless of the intentions behind it.

The ascension of canvas, after all, was fueled by the totes’ compelling social benefits. Not only is canvas a renewable resource, but the bags are biodegradable and sturdy enough to stand up to years of use. With global warming emerging as an everyday anxiety, designers and consumers alike latched on to the reusable tote as a tangible step they could take to help the environment. Reusing canvas bags could reduce—and eventually eliminate—the billions of plastic bags that are discarded every year.

The thought is noble, but it’s worth considering the irony: The plastic bag itself began as an environmental salve. Before the introduction of ultra-thin plastic bags in the 1980s, groceries were primarily packed in paper. Plastic was touted as a way to save trees. Within a few years plastic dominated the market. Comparing plastic to paper, it’s easy to see why; the plastic bag is a vastly superior design. It consumes 40 to 70 percent less energy to manufacture, generates 80 percent less solid waste, and produces 60 percent fewer atmospheric emissions. A plastic bag costs a quarter as much to produce and is substantially lighter (so it takes far less fuel to transport).

What is marvelous about an individual bag, however, becomes menacing when it is multiplied to accommodate a global economy. The low cost allowed merchants to give plastic bags away and, despite their strength, they’re routinely double-bagged. Their incredible durability means it can take up to hundreds of years for them to decompose. Although plastic bags are recyclable, in-store programs have barely managed to achieve a 1 percent recycle rate. It is simply too easy and efficient to keep making and distributing more plastic bags.

We could be headed for the same kind of catch-22 with the adoption of the canvas tote. I’m certainly an outlier in this case, but I recently found 23 of them in my house. Most were given to me as promotional materials for design studios, start-ups, and boutique shops; more than one came from an environmental organization; one even commemorates a friend’s wedding. A community group recently delivered a reusable bag to every house in my neighborhood to promote local holiday shopping.

Can we do anything right? First, we switched to plastic to save trees. Now, we're told paper bags are better than plastic. Re-usable bags became the ticket. Now, you're telling us they're not environmentally sound. I get my canvas bags at yard sales & thrift shops. Some of them I've used for more than 10 years. I'm not about to count individual uses. The fact is any bag is reusable -- plastic, paper, or kumquat. Consumers just need to be educated -- look at the number of news bags being used at the grocery store. People haven't gotten the point yet. Articles like this one defeats attempts to educated about reuse. Hmmm ... why bother if it's all bad. Another point of education is simplify. I buy my produce from a local farmers coop. No bag needed. I buy staples by bulk through another coop. Don't use a bag. I only have to go to the grocery store once a month a most. And, I proudly take my reusable bags.

The way to use canvas bags is to have them barcoded by the supermarket, use the same ones each time and get discount or gas miles or other incentive when used. This helps cut down multiple production of canvas bags. Other methods in the same vein: 1- promote a favorite charity by having the supermarket donate in your name from the same bar-coded bag. might be tax deduction as well. 2. promote a cause. Print bags with slogan, ie; "eliminate plastic bags" 3. since most folks shop at the same market each time, the reusable bag can be tracked and info used for a variety of purposes. 4. When no longer useful, canvas bags can be recycled for making paper.

I had a conversation with my neighbor just yesterday about the stockpile of the new non-woven polyethylene grocery bags I'm amassing. They're great--easier to carry home when one is on foot--but I agree with this article. They're one more thing for me to buy and I am buying them. Dozens of them. They, unlike the canvas bags, are still made from a petroleum product, and they don't last as long. Good things to think about, thanks!
