- What's the final destination of abandoned refrigerators?
The refrigerators are dismantled into their major spare parts in this place.
Various plastic and copper parts, as well as insulation foams, are salvaged from the fridge.
The rigid-foam insulation is made of polyurethane which is widely known as a common environmental pollutant.
A total of 20,000 tons of polyurethane have been dumped in South Korea every year.
The scrap polyurethane is burnt away in a subsequent process, creating toxic gases.
A local research team led by the Korea Institute of Geoscience and Mineral Resources (KIGAM) has developed what it claims is the world's first such technology to recycle the scrap polyurethane into a construction material.
First, the polyurethane foams collected from waste refrigerators are ground into fine powder.
Melting the polyurethane powder results in the liquid polyol which is a key ingredient used in polyurethane formulations.
If the reclaimed polyol is mixed with special substances, a new building insulation material is created.
[Jo Bong-Gyu, senior researcher, KIGAM]
"We plan to further expand our research to develop technologies for recycling other polyurethane foam materials used in furniture, bed mattresses and car seats."
The cost required for the recycling process is only two-thirds of that for the production of polyurethane insulation materials with the conventional technology.
The KIGAM expects the new technology will attract multiple interests from abroad.

Good
Hello, I would like to know which kind of ingredient do you use for diluted or make the polyol recycled
Interested in the technology. Can this be used for rigid PU like shoe sole, car parts etc?? Let's get connected.
Can I get details /contact details of this recycling company .

Hi, What outer layer are you using?
Pp non woven
@@Nomad_Wanderer Do you know any supplier sell it? I'm finding it. Thanks
I'm from Indonesia, I need this information
2/3 of original cost does not reduce costs "sharply".
yeah, not as sharp as expected but it also reduce toxic gas created from burning it
Hi, we wanna apply this technology in Viet Nam, how to contact with machinery supplier?
South chungcheong pronvince
I need it for india, can you please assist us?
India? Hmm.. call me
Do you need urethane board?
Do you have the company contact?
I have why??
I would like to know about process, and the techonolgy have been used. Thanks
process... Do you want to urethan board machine? Pur or pir , 141b or cyclo pentane ?
@@뜬다 I mean the technology or machine of polyurethane recycling like in this video. Sorry I don't understand the meaning of pur/pir and 141b or cyclo pentane.
@@뜬다 i want to know more about the production process of this reciclage
