The introduction of biomass as a substitute for petroleum-based raw materials will make a significant contribution in the development of sustainable products.
In May 2009, The Coca-Cola Co. unveiled its new package. According to the press release, the PlantBottle™ is fully recyclable, has a lower reliance on non-renewable resources, and reduces carbon emissions compared with polyethylene terephthalate (PET) plastic bottles. The rest of the press release discusses the environmental virtues of the new package, but dialogue with Coke employees revealed a different (though equally important) driver: “We have been in business for over 100 years and we plan to be in business for over 100 more years. We are taking steps now to reduce our dependence on petroleum-based raw materials.”
Many biodegradable polymers are suited for adhesive applications, such as environmentally friendly packaging, recyclable envelope adhesives and biomedical devices.
Significant advances have been made over the past 20 years in the development of biodegradable polymers. These materials have been developed in a variety of forms, and thus have potential use in a range of industries, including adhesives.
Starch- and dextrin-based adhesives play a large part in industrial production, especially the packaging industry.
