Dow Makes Energy from Recycled Plastic


Pilot Test Successfully Demonstrates Ultimate End-of-Life Option for Recycled Plastic

MIDLAND, Mich. - May 23, 2011

The Dow Chemical Company (NYSE: DOW) announced today that it has successfully demonstrated the use of recycled plastic to generate energy. The successful pilot test measured how plastic that has been reused and recycled to the full extent possible can be used as fuel for an ultimate end-of-life option instead of going to a landfill for disposal.

The pilot test found that 96 percent of available energy was recovered after incinerating 578 pounds of used plastic in a kiln at one of Dow’s waste treatment facilities. The energy recovered was equivalent to 11.1 million Btu’s of natural gas and was used as fuel for Dow’s incinerator during the test. The trial was completed in compliance with regulatory permits.

Linear low-density polyethylene (LLDPE) scrap film generated in one of Dow’s extrusion laboratories was used in the test. The film was the same type commonly used for packaging food and consumer products. The test took place at Dow’s second-largest U.S. manufacturing location in Midland, Mich.

“The purpose of the test was to collect data showing that used plastic can provide a valuable source of energy and ultimately help reduce our need for natural gas or other fossil fuels,” said Jeff Wooster, Plastics Sustainability Leader for Dow’s North American Plastics business. “The study results demonstrate that almost all of the available energy stored in used plastic can be captured and reused as opposed to being buried in a landfill.”

While most thermoplastics can be reprocessed, there currently are limited end-of-life options for certain types of used plastic packaging, such as some flexible films and containers made from a combination of materials.

“Energy recovery and chemical transformation do not replace the traditional means of recycling plastics – they extend and complement it,” Wooster explained. "The U.S. lags behind many other countries that capture trapped energy from recovered materials. Recovering embedded energy in recycled plastic is a ‘best-in-class’ approach used in Europe and other regions. Our next step is to help find a way to scale up this more sustainable practice in the United States.”

The sustainability advantages of energy recovery include utilizing natural gas or oil first to make plastics, which can then be used, reused, recycled and recovered at end-of-life, capturing the energy content of the original feedstock. Energy recovery allows more utility captured from every natural gas or oil molecule.

“Energy recovery is a clean, reliable, renewable source of energy having less environmental impact than many other sources of energy,” Wooster explained. “We look at this endeavor as another way in which Dow can deliver on its core value of protecting the planet – by harnessing its innovation engine to help customers, communities and society while encouraging others to do the same.”

The recycle-to-energy recovery trial provided the concept validation for the submission and approval of one of several energy efficiency projects recently chosen to receive funding through Dow’s Energy Intensity Improvement Fund. The $100 million investment fund targets Dow projects designed to help reduce energy usage and greenhouse gas emissions.

Dow is committed to working with value chain partners, industry associations and others in the field to increase the availability and viability of end-of-life options including mechanical recycling, chemical transformation and energy recovery. These efforts are another step Dow is taking toward achieving its long-term vision of recycling 100 percent of used packaging.
