  • NEA | General Waste Disposal Facility

    As part of efforts to safeguard public health and the environment, NEA started licensing general waste disposal facilities from 1 August 2017. Effective 1 August 2018, all general waste disposal facilities must either obtain their licence or submit an exemption declaration.Use of waste copper slag, a sustainable material | Request PDF,Use of waste copper slag, a sustainable material.,and proper management and disposal of huge volumes of copper mine tailings arising thereof is a huge challenge.NEA | Collectors, Traders and Local Recycling Facilities,In Singapore, private companies set up recycling facilities to recycle different types of waste, for example, food, plastics, metals, steel slag, spent copper slag, tyres/rubber, horticultural, wood, electronic waste, as well as construction and demolition waste into useful resources.Characteristics and utilisation of copper slag—a review,,Granulated copper slag is more porous and therefore, has lower specific gravity and higher absorption capacity than air-cooled copper slag. The granulated copper slag is made up of regularly shaped, angular particles, mostly between 4.75 and 0.075 mm (No. 200 sieve) in size (Emery, 1986, Hughes and Haliburton, 1973).Cement-based solidification for the safe disposal of,,The mortar incorporating waste copper slag up to 10% replacement is, therefore, safe with respect to leachability of the above metal ions. The compressive strength of copper slag mortar was found to be lower than that of OPC mortar. The safe disposal level of copper slag in mortar for optimum strength performance was about 5%.MATERIAL SAFETY DATA SHEET,- COPPER SLAG - 1.
