New Building Materials Update -December 13, 2008

With all of the news pointed at alternative energy and like stories it is refreshing to see progress being made on some of the other products that go into your buildings.

We have a couple of inovative insulation products the first being recycled blue jeans! The story at Cleantechnica.com (http://cleantechnica.com/2008/12/02/bonded-logic-insulation-made-from-recycled-jeans/) is a very interesting example of what can become useful with a little thought!

Excerpt: “Ok, the company actually takes post-industrial denim and cotton fibers (basically, the stuff that never became jeans) rather than the jeans that you’re tired of, and uses that as the major component (85%) to create LEED-applicable commercial and residential insulation.

Because of this feedstock and the process used to create the insulation, the insulation created by Bonded Logic doesn’t contain any chemical irritants or carcinogens. You can buy it at Home Depot, and get your kids to help you install it at home.

The other is a wall product being made for loofahs!  Actually it is a hybrid product that includes the loofahs and other recycled materials (http://ecopreneurist.com/2008/12/11/the-next-green-building-material-loofah/).

Excerpt: ” So she wondered what use/value could be created from these. Material for house walls and roofs, she decided. After extensive trial and error, she and Padros devised the perfect combination of loofah, recycled plastic, and things like cotton netting and corn husks, all of which would otherwise be disposed of. At less than $3 a square meter, competitive with wood.

But beyond being merely equivalent in price, it exceeds wood’s capabilities, with the ability to take dye during manufacture, making painting unnecessary. They are flexible, able to better withstand disaster situations. If they do fall, there’s less chance of injury, as they’re lighter weight. And they can be recycled, repeatedly. And with care in initial selection of plastics, when they can no longer be remade into housing material, they can be used as biofuel.

While totally viable as a building material in many environments far outside rural Paraguay, their ease of use, and ability to work with local, familiar materials like adobe makes them ideal for use locally, providing both shelter and income.
