The current global emphasis on environmental sustainability has led to a keen interest in developing polymers and related technologies that are eco-friendly and sustainable. In this regard, significant research efforts are being undertaken worldwide, where sustainable polymer-based research is rapidly emerging as a field with considerable promise and potential. The Fourth International Symposium on Advances in Sustainable Polymers (ASP-17) to be organized from Jan 8 to 11, 2018, is aimed at providing a platform for researchers to share recent state-of-the-art advances in the area of sustainable polymers. The symposium will include plenary talks and invited talks on recent advances in several aspects of sustainable polymer-based technologies.
