Plastics and Sustainability Grey is the New Green
Wiley-Scrivener (Verlag)
978-1-119-59184-9 (ISBN)
Increased public scrutiny of plastics materials and the plastics industry has led, paradoxically, to both a deeper understanding and growing confusion about polymers, their origins, their uses, their risks, and ultimately their disposal. The author makes objective comparisons among major polymer grades and bioplastics including their life cycle assessments and practical performance in commercial applications.
Michael Tolinski (Deceased, 2016) was the Managing Editor of Plastics Engineering magazine (SPE/Wiley), author of Additives for Polyolefins (2009) published by Elsevier/William Andrew's Plastic Design Library, and Plastics and Sustainability, 1st edition (2012) published by Wiley-Scrivener. Conor Carlin is the Managing Director of ILLIG LP, the North American subsidiary of ILLIG Maschinenbau GmbH & Co., a Germany-based designer and manufacturer of thermoforming, tooling, and packaging systems. A member of Society of Plastics Engineers sinc 2000, he serves as editor for SPE Thermoforming and Recycling Division publications. Carlin has contributed articles on plastics and sustainability for international industry press in the US, Europe, and Asia. In 2017, he was elected to the SPE Executive Board as VP of Marketing and Communications, and re-elected in 2020 as the first VP of Sustainability. For 10 years he was an active mentor to cleantech startups in the Boston-Cambridge cluster, focusing on energy efficiency and biofuels. Carlin has degrees from Boston University (BA, International Relations / French) and the FW Olin Graduate School of Business at Babson College (MBA).
