Once construction waste is generated, source separation will be conducted by workers to prevent waste materials being mixed. Basically, there are four The most important step for recycling of construction waste is on-site separation. Initially, this will take some extra effort and training of construction personnel.

In the study by Shen et al. [12], several major weaknesses of on-site CWS practices in Hong Kong were presented and discussed, including: (W1) lack of waste sorting-out process, (W2) no consideration for recycling waste, (W3) intensive labor work involved in handling waste, (W4) double-handling in collecting waste, and (W5) time Responsible management of waste is an essential aspect of sustainable building. In this context, managing waste means eliminating waste where possible; minimizing waste where feasible; and Construction Waste Management Whole Building

On-site sorting of construction and demolition waste in Hong
The feasibility of on-site waste sorting is examined respectively in construction and demolition sites. For construction waste, alternative 1 is the most applicable on-site sorting method. It involves two refuse chutes set up for each building block for debris collection, enabling separation of non-inert materials from inert materials Abstract. Construction and demolition waste (CDW) substantially contributes to environmental degradation because of its intrinsic characteristics of fast and high generation volume, low recycling rate, and low revenue margins. A systemic problem is that recycling facilities are not usually a part of a reverse supply chain (RSC) specific for CDW.Reverse supply chain conceptual model for construction and demolition waste

Previous research indicated that on-site CWD separation and recycling is one of the most important CDW recycling methods: it increases the proportion of reused and recycled building materials, reduces land resource consumption and landfill pollution, and waste transportation and disposal costs [17].recycle and landfill waste. Off-site recycling is also known as commingled or single-stream recycling. On-site recycling also referred to as source-separated recycling involves several dumpsters. Each material goes into a different container to lower the chances of cross-contamination.

Since separation for recycling is now already performed in the middle processing institutions as well, if we separate waste on construction/ demolition sites, separation efficiency will be greatly improved.

According to [18], the on-site recycling technique is the isolation of the construction waste and then is used as a raw material in other construction processes. Meanwhile, the off-site recycling technique is the separating and transporting of the construction waste to other organizations so that it can be use as the raw material.To overcome these issues, autonomous robots are designed to pick up and sort waste according to the material type.

Implementing on-site construction waste recycling in Hong
Construction and demolition (C&D) waste recycling constitutes an indispensable component in the overall waste management strategy. Unlike the traditional recycling approaches whereby C&D waste is transported to off-site facilities for treatment, construction managers are actively exploring the possibility of on-site recycling where The scientific community has revealed the environmental benefits of recycling construction waste (CW) versus its disposal, and its contribution to circularity. The Life Cycle Assessment (LCA) method enables the environmental impact of CW management to be quantified and facilitates the comparison of recycling versus Environmental Impact Assessment of Construction Waste Recycling

This paper focus on air jigging separation studies for removing brick particles from recycled construction and demolition waste aggregates. The operational parameters were achieved by studying the aggregate movement trajectories based on the small specific density differences of 2.52 g/cm 3 and 1.97 g/cm 3. Separation tests were Guide. The construction industry uses many different types of materials in large quantities. This means there are many opportunities for construction businesses to increase the amount of waste they reuse or recycle.
