RENOVATION RENOVATION WASTE WASTE WASTE MANAGEMENT MANAGEMENT MANAGEMENT PROJECTS PROJECTS PROJECTS
RENOVATION RENOVATION Planning and Design Waste Reduction Principles MUST be established from Day 1 • Recycled existing loose furniture, fixtures and equipment • Reused existing teakwood flooring • Recycled all doors • Use of proprietary reusable protection system • Use of pre-cast partition wall panels • Redesigned corridor carpet to reduce off-cuts • Reused existing marble
RENOVATION RENOVATION Planning and Design Recycled existing loose furniture, appliances and fittings Furniture items and fittings (kitchen appliances, TV sets, sanitary fittings and doors) handed over to Mok & Lockwood Joint Venture to recycle : • 40% to a 4-star services apartment located at Port Dickson, a popular beach resort in Malaysia . • 30% to a group of timeshare holiday apartments in 3 resort locations in West Malaysia . • 20% to an suburban Melbourne Motor Inn. • 10% was retailed to various individuals in Kuala Lumpur .

RENOVATION RENOVATION On-site Management Consists of: • A Waste Management Plan and Report • Mandatory Material Sorting/Recycle and Reuse of C&D Waste • Identifying Reusable Items • Conducting Regular Site Audit
RENOVATION RENOVATION On-site Management Mandatory material Sorting/Recycle and Reuse of C&D Waste Recycled Items : Copper Piping, Light Troughs, AHU/PAU Coils, Fire Dampers, Fan Coil Units
