Recyclability potential index rpi the concept and quantification of rpi for textile fibres
Ecological Indicators, 2012Co-Authors: Subramanian Senthilkannan Muthu, P Y MokAbstract:Abstract A focus on recycling is one of the key pillars in this environmentally conscious era. In recent times, the situation is forcing people to recycle everything that are produced due to various factors such as present and future projections of scarcity of potential resources, limited landfill space, governmental policies, rewards in terms of monetary benefits given to people when they return the product for recycling. Textile products, occupying a significant proportion of one's daily activities in almost every place, need to be recycled. Many types of fibres are being used to manufacture textile products for daily use and they necessarily need to be recycled at the end of their lives. The potential Recyclability of different fibres varies from one fibre to another and many factors play a major role in deciding their Recyclability. This study proposes a concept for the Recyclability Potential Index (RPI) of textile fibres considering their environmental and economic gains from the recycling process and also attempts to quantify the Recyclability Potential Index (RPI) of ten common, widely used textile fibres. According to the developed system, polyester and polypropylene seem to be bestowed with higher and the nylon 66 appears to have the lowest RPI.

mesoporous silica supported catalysts for metathesis application to a circulating flow reactor
Chemical Communications, 2010Co-Authors: Jaehong Lim, Su Seong Lee, Jackie Y YingAbstract:Using click chemistry for linkage, a ruthenium-based metathesis catalyst was efficiently immobilized on nanoporous silica. The heterogenized catalyst exhibited good activity and Recyclability for various substrates. An interesting application was demonstrated for a continuous process using a circulating flow reactor.

silica supported catalysts for ring closing metathesis effects of linker group and microenvironment on Recyclability
Chemical Communications, 2008Co-Authors: Jaehong Lim, Su Seong Lee, Jackie Y YingAbstract:The interesting effects of the linker and microenvironment on the Recyclability of well-defined silica-supported catalysts were examined, which demonstrated the excellent activity and reusability for the ring-closing metathesis (RCM) of a number of substrates.

mesocellular foam supported catalysts enhanced activity and Recyclability for ring closing metathesis
Advanced Synthesis & Catalysis, 2007Co-Authors: Jaehong Lim, Su Seong Lee, Siti Nurhanna Riduan, Jackie Y YingAbstract:Although ring-closing metathesis (RCM) has been one of the most powerful methodologies for creating cyclic compounds, the pharmaceutical industry has not yet widely adopted this process commercially due to the high costs and leaching problems of homogeneous ruthenium catalysts. To circumvent these problems, we have immobilized the second-generation Hoveyda–Grubbs catalyst effectively onto siliceous mesocellular foam (MCF). The open and interconnected pores of MCF facilitated ligand immobilization and substrate diffusion. We have observed that the ligand and metal loadings significantly affected the catalytic activity and Recyclability. Enhanced Recyclability by suppression of ruthenium leaching was achieved by using excess immobilized ligands. The resulting novel heterogenized catalysts demonstrated excellent activity and reusability for the RCM of various types of substrates.
