Sustainable Materials
Sustainable materials are materials that can be regenerated usually by biological action without limit.Sustainability is one of those terms which seem obvious but coming up with a clear, measurable definition is not so easy. Tullo in an editorial in Chemical & Engineering News, 4/19/2010 defined sustainability as “being able to keep on doing what you have been doing”. His editor, Rudy Baum defined sustainability as “learning to live off the sun in real time”. The point of the editorial was about measuring quantitatively how companies are doing in terms of sustainability. Both these definitions actually seem to reflect the point of sustainable materials. Petroleum based plastics certainly are not sustainable while linseed oil based coatings are. (RDC 4/21/2010)

Prime foam containing vegetable oil polyol
Willaim Briggs of Sleep Innovations has developed a polyurethane foam using an isocyanate, a sufactant and a polyold blend of petrochemical and vegetable oil polyols. The formulation contains 1 to 70 percent vegetable polyol. (RDC 6/21/20100)

Synthesis and characterization of new benzoxazine-based phenolic resins from renewable resources and the properties of their polymers
(2843–2848)Journal of Applied Polymer Science 122 #5 (2011)
Li et al ofWuhan university of Technology and Huangshi Huibo Anticorrosion Technology of China, synthesized two types of novel benzoxazine-based phenolic resins from phenol-furfural (PFB) and cardanol-furfural (CFB) resins and the highly thermally stable polybenzoxazines were obtained by the thermal cure of the corresponding benzoxazine-based phenolic resins. Thermogravimetric analysis indicated that the incorporation of furan groups could enhance the char yield and thermal stability. However, the long alkyl side chain from cardanol could increase the toughness, while decreasing the char yield and thermal stability. (RDC 9/6/2011)
