PROJECT
RCLG 2.0
FOR CONSTRUCTION AND
DEMOLITION WASTE IN NSW

2. THE ISSUE
The tracking and reporting of construction and
demolition waste is cumbersome and fragmented
across the construction industry. The need for tracking
and reporting for compliance relies on outdated paper
dockets and manual data entry systems that are prone
to error and manipulation. Understanding what waste is
generated, where is goes, and what happens to it is
crucial for compliance, reporting and is a key enabler for
a circular economy in NSW.
PROJECT OVERVIEW
The Digital Twins Project for construction and demolition waste
aims to develop a pilot scale demonstration of the application
of digital twins for the tracking of construction and demolition
waste from generation on site through to recycling, reuse, or
disposal. The data will provide Government and Industry with
actionable insights to help with reporting, deploying resources,
identifying opportunities to improve waste management, and
as a potential enabler of a more circular economy in NSW.

demonstration
04
Provide a report on key findings
and outcomes for Government
and Industry
WHAT IS A DIGITAL TWIN?
A Digital Twin is a digital model of a real-life object, process or system. The digital model
can be informed by historical data and fed with live sensor data to make the digital model
identical – a ‘twin’ – to the real-life subject. Digital Twins of discrete systems can be linked to
create twins of larger, more complex systems such as a factory or a city. (NSW Government
Emerging Technology Guide).
