Recycling Could Solve Pesky Polypropylene Carpet Problem
Written by Tina Casey

Yowzers – according to the U.S. EPA, about four billion, yes billion pounds of carpet go into the waste stream every year – much of it is used, some is new carpet left over from building construction. A lot of that carpet (and carpet backing) is made of cheap, durable polypropylene fiber, which makes up about 80% of the sales for commercial carpet.

Polypropylene, aka olefin, may be familiar to recycling addicts through its #5 plastic recycling designation, a number that can spell trouble. Until now, recyclers have been slow to adopt #5, partly due to the expense of separating it from other materials. Used polypropylene carpets on the other hand offer good potential for cost effective processing due to their sheer bulk and availability.

Polypropylene, Carpets and More
Because of its relatively low cost and high durability, polypropylene has a few other uses aside from carpets including ropes, plastic containers (margarine, yogurt, etc.), bottle tops and “living” hinges (think Tic-Tacs), lab equipment, auto parts, piping, furniture, consumer electronics and toys (cell phones, loudspeakers and Rubik’s Cube), lampshades, kettles, surgical materials, buckets, pitchers, model aircraft (in its foam form), car batteries, jewelry, stationery folders and storage boxes, coolers, air filters, insulated cable, diapers (disposable, natch), and activity wear (Under Armour). There is even polypropylene currency, if you can believe it. The annual global market for polypropylene adds up to about 45 million tons – a recycling gold mine ripe for the picking.

Polypropylene Recycling and Axion Polymers
Axion Polymers is a recycling specialist in the U.K. that has just announced it is ready to do some polypropylene picking, working with Carpet Recycling UK Ltd. and the public organization Envirolink Northwest. The company has developed a method for recovering polypropylene from used carpets and converting it into pellets. In this form the material is not suitable for manufacturing sensitive products such as lab equipment or food containers, but it could be reformed through injection molding into things like plant pots, compost bins and buckets. Last year Axion undertook trial runs on a small scale that showed promise, and now it’s ready to embark on larger trials to demonstrate cost-effectiveness.

The Future of Carpet and Polypropylene Recycling
Axion has found that the key to cost-effective recycling of polypropylene carpets starts at the beginning, by selectively targeting “pure” polypropylene carpets for the process. Carpets that contain mixed fibers are not suitable for this form of recycling, but at least it’s a start toward getting more #5 plastic out of the waste stream. In the U.S., carpet recycling is starting to take off in San Francisco among other places, and companies like Aveda, Organic Valley and Stoneyfield Farms are focusing on small #5 plastic items like bottle caps and yogurt containers.

$6 million to support green jobs in Washington
by KING5.com and Associated Press

WASHINGTON – Washington state is receiving nearly $6 million in federal stimulus funds to promote clean energy jobs.

Labor Secretary Hilda Solis says the money will go to the Washington State Workforce Training and Education Coordinating Board to train about 4,700 people.

The grants are for people with disabilities, veterans and those who have been laid off.

Sen. Patty Murray said the grant will help nearly 5,000 Washington state workers get the skills and training they need to succeed in the growing clean-energy industry.

“Washington state is a national leader in the clean-energy sector and this grant will help ensure that our workforce remains strong and able to fill the jobs of the 21st century economy,” she said.

Training includes energy management and auditing.
