COVER FEATURE INGENIEUR RECYCLING & ENERGY RECOVERY By Chin Siew Yin W hen the Malaysian Government conducted a study on National Waste Minimization in Malaysia in 2006, an ambitious target of recycling rate of 22% was set by 2020. The exercise started with an awareness programme which claimed a good success rate although in practice, it was another matter. The incorporation of mandatory source separation of waste in the Solid Waste and Public Cleansing Act, Act 672 in 2007 was one way to increase the recycling rate under the 3R programme. The United Nations Environment Programme (UNEP) and ISWA (Institute of Solid Waste Association) are of the view that we have to ensure recycling and energy recovery are compatible in order to close the material cycle. The related contents of the publication under the “Global Waste Management Outlook” is a good guide for the stakeholders involved in the waste management industry. CLOSE THE MATERIAL CYCLE A key part of the circular economy is to build ‘feedback loops’. Recycling is part of natural processes, and re-establishing this circularity is a key component of overall sustainable development. There are limits to recycling, at which point energy recovery needs to be considered. 6 24 VOL – DECEMBER 2015 VOL64 55OCTOBER JUNE 2013
