Assessing construction and demolition waste generation rates using satellite imagery
Municipal solid waste management has seen a surge in the use of satellite imagery in decision-making processes, yet its application to analyze quantitative variations in construction and demolition (C&D) waste remains underexplored. Especially the COVID- 19 pandemic disrupted conventional municipal …

Developing a cost effective construction and demolition waste management plan
Concern over construction and demolition (C&D) wastes is becoming a prevalent part of any construction project. Historically, landfilling waste materials was the standard solution for most contractors, but as tipping fees have risen dramatically over the past five to seven years, many contractors …

The use of construction and demolition waste in concrete in Cape Town
… to promote the use of RAs, a construction and demolition waste (C&DW) recycling culture has to be developed. Analysis of municipal waste data over the past 10 years shows that the commercial aggregate industry and market has not grown. A major contributor to the excess C&DW in the City, is the …

Determination of Size Fractions and Concentrations of Airborne Particulate Matter Generated From Construction and Demolition Waste Processing Facilities
Construction and Demolition (C&D) processing and recycling facilities accept waste materials that are generated during construction and demolition activities. The processing facility sorts, processes, and transfers the material to another operation. A consequence of these processes is the …

A BIM-based Object-oriented Data Model to Support Sustainable Demolition Waste Management Decision Making at End-of-Life
Sustainable demolition waste management is rarely practiced within the construction industry. This is mainly due to the fact that the decision-making process for sustainable demolition waste management is a very resource-demanding and time-consuming task in terms of data collection and data …

The Matter of the Hold: Housing futures and the paradigm of the ship
… Oftentimes, this material was sourced from waste, such as stone offcuts from quarrying, and transported across space and time, slipping through value systems; from waste, to weight, to commodity. In time, structures across the continent boasted chimneys or foundations that had begun their …

From Waste to Structure: A Deep Reinforcement Learning Approach to Circular Design
… in this manner is resource-intensive and wasteful, making it incompatible with our global climate goals. One way to significantly reduce our material and environmental footprint is by extending the lifespan of building materials through circular design practices. In this approach, the …

Characterisation and behaviour of recycled concrete and bricks as engineered fill.
Demolition waste materials mainly consist of concrete and bricks and arise from the demolition of existing structures and buildings. Environmental and economical reasons make their recycling necessary but up to date little research has been undertaken to what is perceived as low level reuse of …
