Disposal in landfill is the worst option but recycling post-consumer plastic waste presents a technological nightmare given the huge range of polymers used in packaging and products. A rapid, online method of identifying the different plastics in a recycling stream would provide a way to sort them and allow recycling plants to operate far more efficiently and perhaps make plastic recycling commercially viable.<br /><br />A technique being investigated by Spanish researchers to this end is laser-induced plasma spectroscopy (LIPS). Jesús Anzano, María-Esther Casanova, María-Soledad Bermúdez, and Roberto-Jesús Lasheras of the Laser Analytical Spectroscopy Lab at the University of Zaragoza, in Spain, have now demonstrated that LIPS used in conjunction with a simple statistical correlation method can indeed differentiate between plastics prior to recycling.<br /><br /></span><a href="http://www.unizar.es/janzano/images/SN10b_A_plastics.jpg"><span style="font-family:verdana;font-size:85%;"><img style="FLOAT: right; MARGIN: 0px 0px 10px 10px; WIDTH: 208px; CURSOR: hand; HEIGHT: 184px" height="195" alt="" src="http://www.unizar.es/janzano/images/SN10b_A_plastics.jpg" border="0" /></span></a><span style="font-family:verdana;font-size:85%;">Among the most commonly used household and industrial plastics are polyethylene terephthalate (PET), high-density polyethylene (HDPE), polyvinyl chloride (PVC), low-density polyethylene (LDPE), polypropylene (PP), and polystyrene (PS). The team has developed a compact LIP spectrometer with which they obtained LIP spectra for these polymers in the 200-800 nm range and compared them with library spectra of recycled plastic samples. The researchers have also developed a computer program for data acquisition and data processing that exploits linear and non-parametric (rank) correlations to classify the spectral data.<br /><br />"The robustness of the technique was demonstrated by the 90-99% reliable identification of almost all analysed plastics," the researchers says, "The technique has excellent potential for on-line, real-time analysis of recycling materials," they say.<br /><br /><br />Related links: </span><br /></p><ul><li><a href="http://dx.doi.org/10.1016/j.polymertesting.2006.04.005"><span style="font-family:verdana;font-size:85%;">Polym Testing, 2006, in press </span></a></li><li><a href="http://www.unizar.es/janzano"><span style="font-family:verdana;font-size:85%;">Laser Lab, Zaragoza </span></a></li></ul><br /><br /><br /><div><br /><a href="http://www.spectroscopynow.com/coi/cda/detail.cda?id=567&amp;type=Feature&amp;chId=0&amp;page=1"><span style="font-family:verdana;font-size:85%;">Article by David Bradley</span></a></div></div><div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4596206033500604246-2125168622366845378?l=laslab.blogspot.com' alt='' /></div>Jesús Anzanohttp://www.blogger.com/profile/11816767492119461480noreply@blogger.com0tag:blogger.com,1999:blog-4596206033500604246.post-22397448522343641392008-02-20T11:16:00.000-08:002011-02-08T10:52:55.307-08:00LABORATORIO LÁSER<br />Universidad de Zaragoza<br /><br /><br /><br />JESÚS ANZANO LACARTE<br />JUSTINIANO CASAS GONZÁLEZ,<br />ROBERTO-JESÚS LASHERAS MOLINA<br />CRISTINA BELLO GÁLVEZ<br />SONIA SANGÜESA VILAR<br />ELIANA GASPAR MORENO<br />MAYTE BENEDED SERRANO<div class="blogger-post-footer"><img width='1' height='1' src='https://blogger.googleusercontent.com/tracker/4596206033500604246-2239744852234364139?l=laslab.blogspot.com' alt='' /></div>Jesús Anzanohttp://www.blogger.com/profile/11816767492119461480noreply@blogger.com0tag:blogger.com,1999:blog-4596206033500604246.post-53640028326757653472007-07-25T11:27:00.000-07:002007-07-25T11:34:40.502-07:00El pasado 12 de julio Roberto Jesús lasheras defendió su Tesis Doctoral, obteniendo la calificación de sobresaliente "Cum Laude".
