Solution: Turning plastic bottles into thatched roofs

The previous post, “The ghosts of our consumption,” illustrates the scourge of plastic on sea life. Could plastic thatch roofs be a solution?

Betsy Teutsch writing in The Atlantic:

“David Saiia, a professor of strategic management and sustainability at Duquesne University, has come up with a brilliant alternative: plastic thatch from the huge amount of discarded plastic.”
“Saiia specializes in developing business solutions that will help people out of poverty while preserving habitats. On one of his many trips taking university students to the Ecuadoran nature preserve, Maqui Picuna, he challenged them to think of something useful to do with all the plastic bottles littering this scenic Andes cloud forest. Saiia’s sculpture, painting, and drawing skills kicked in; shortly a proverbial back-of-the-envelope drawing launched his business transforming bottles into thatch strips. The tops and bottoms are sliced off; the remaining body of the bottle is flattened and then cut into strips. (Saiia and Carnegie Mellon’s Engineers without Borders are now tweaking a human-powered machine to do this work.) Next, the strips are adhered to a cross-strip using ultrasonic sealing machines provided by Dukane. If you’ve ever sliced yourself wrestling with a device encased in clam-shell plastic, you know how effective ultrasonic sealing is.”

Replacing traditional thatch roofs with corrugated tin roofs creates homes trap heat and produce deafening noise when it rains. Plastic thatch roofs are a quieter, longer lasting solution.

“Albatross chicks eat what their parents feed them, plastic included.” Unfortunately, the ocean is now littered with plastics “including pieces of shotgun shells, paintbrushes, pump spray nozzles, toothpaste tube caps, clothespins, buckles, toys - just to name a few.” Their parents “mistake the trash for food as they forage the vast, polluted Pacific Ocean.”

Patagonia, the new local economy, and fabric recycling

Patagonia.jpg

Yesterday I took the day off. Yes, in the middle of the week, unusual. I drove to Boulder and took an easy hike in Chautauqua Park at the Flatirons base, my first hike since the cycling injury. After lunch, I strolled along Pearl Street and stopped into the Patagonia store. One of the first things to catch my eye was the book let my people go surfing: the education of a reluctant businessman by Patagonia founder Yvon Chouinard. 

In the Preface, Yvon lays out new directions for Patagonia brought on through reflections on sustainability:

At Patagonia we have started to prepare for what we think will become a more locally based economy. A global economy based on cheap transportation is not sustainable. Our present mode of production includes buying organic cotton in Turkey, shipping the bales to Thailand to be processed into fabric, shipping the fabric to Texas to be cut, to Mexico to be sewn, on to our warehouse in Reno, then to our stores and dealers, and finally to our customers' homes.

The retail price of regular gas 10 years ago (May 8, 2001) was $1.427 per gallon. Today it is $3.963. If petroleum prices continue to increase at same rate over the next couple of decades, it wont be sustainable at all.

Another direction for Patagonia is to "start making all clothing from recycled and recyclable fibers." This is a dramatic change, one that will likely take years, and may never fully materialize. But for a company already a leader in sustainability, it signals a new direction that other companies will likely emulate. Beginning with the Common Threads Recycling Program:

We seek to close the manufacturing and consumption loop in the way the modern aluminum industry works. We'll collect from our customers their worn out polyester garments and send them back to Teijin for recycling into new polyester fiber. ...With the extra shipping, the program still yields energy savings of 76% and reduction in greenhouse-gas (CO2) emissions of 71 percent, compared to the creation of polyester fiber from new, petroleum based raw material.

Those savings are sure to generate interest among competitors. However, as always, customer choices drive the market.
