Naimish Patel1, Mr. Smit Sachapara2, Mr. Jayesh Variya3, Mr. Yash Vyas4 1,2,3,4 B. In India infrastructural generation have risen due to the rapid growth of towns and facilities are increased due to the construction, refurnishing cities.

Due to the increase in the economic growth after and explosion of buildings, bridges, runways, flyover, roads, development and redevelopment projects in the country and factories, industries, hospitals and other similar subsequent increase in the urbanization in the cities has made formulations.

So there is a need of proper site work. The primary method is adopted in waste handling planning of waste management and recycling of waste is carried through by interviewing professionals like project material. In India being developing countries, there is managers, architects, civil engineers, contractors and immense need of awareness for waste management. Due to government officials like city engineers, solid waste lack of awareness waste management project is not working management officials.

From the last few decades, European countries make excessive growth on the waste management and utilize the The agriculture is the largest industry in India. According construction waste and recycling that waste. Material is the major part of all types constructions projects. In country like India where on one hand side the growth of development and 1. Today the environmental issues such as flood levels due to o It is very difficult to dispose plastics. Plastics reduces the possibilities of cracking.

As these processes involve sustainability in environmental, economic and social terms, they may create problems and hence need multi-criteria decisions at every stage of its life cycle Melare et al.

Managing solid waste would, therefore, be very costly Lamichhane, While, Construction and Demolition Waste Management CDWM is considered as an inter-disciplinary area as it involves social, environmental, economic, institutional and political aspects while it faces challenges from the perspective of engineering, technology, management and policies and legislation Arshad et al.

Nonetheless, recent studies have focused on finding solutions with the use of advanced Information and Communication Technologies ICTs to face those challenges in waste management. Rapid improvement in the capacity of innovative technologies enables digitisation, automation, and integration of the construction process at all stages Oesterreich and Teuteberg, Several past studies have recognised the potential use of various ICTs brought by the revolution of industry 4.

These emerging ICTs are being adopted in different solid waste management processes to provide widespread solutions to achieve the goals of sustainability Melare et al. This bounds understanding of their potential application, where the construction sector is ignorant hence is not yet ready to transmit and extract their real value in CDWM.

In this context, the objectives of this study are twofold. The first is to evaluate the extent of current adoption and potential use of smart technologies and ICTs in SWM and the second is to outline the potential applications of such technologies in multiple processes of CDWM. Melare et al. ICTs improve effective practices in terms of planning and management and help managers to make informed decisions on environmentally related issues Melare et al.

However, the application of these technologies has not fully implemented in the sector Jin et al. The construction industry is recognized as the second least industry in adopting the technologies and systems across the construction value chain Agarwal et al. Some researchers have recognized that the lack of the use of advanced technologies in CDWM hinders the development of effective management practices in the construction sector.

The issues identified with the lack of usage of advanced technologies in WM are lack of historical waste data, inconsistencies in waste data reporting, inaccuracy in waste estimation and lack of established platforms for promoting the circularity of recovered waste materials through reusing, repairing and recycling.

In contrast, Melare et al. Contributions of ICTs become substantial in handling the issues associated with increasing solid waste, which in turn has urged the need for the automation of waste data acquisition, identification, communication, storage, and analysis Hannan et al. For instance, Zaman and Swapan highlighted the need for a uniform data capture platform to obtain more reliable and compatible data on waste estimation which could provide appropriate developmental directions for benchmarking of WM in the future.

Wu et al. In the first stage, to limit the scope of the research, a keyword search in Scopus and Google Scholar were conducted. Several keywords were applied to find related publications. Besides, publicly available applied publications such as technical white papers, and other commercial web pages were reviewed to identify the use of ICTs and other smart technologies in commercial based SWM systems online platforms to which no peer- reviewed articles were found.

To understand and analyse the potential use of such technologies in CDWM, the current adoption of smart technologies in SWM was reviewed. Table 1 presents a summary of the current status of the application of various types of spatial, identification, data communication and acquisition technologies in several processes of SWM and CDWM. Jin et al. For example, Jin et al. As such, the following sections briefly discuss the proposed applications and likely usage of some advanced technologies in different CDWM processes.

The issue of insufficient data quality has been addressed with the use of Big data in a study by Lu et al. Furthermore, Chen and Lu have used Big data analytics to examine the inter-relationships among waste generation and multiple factors such as demolition cost, demolition duration, and public-private nature of a building project by connecting several databases.

In addition to the function which facilitates estimating the generated demolition waste, GIS can be used as an environmental impact assessment tool. For example, Mastrucci et al. RFID can stimulate the reuse of construction components and reduce their wastage Iacovidou et al. According to Iacovidou et al. While Zhang and Atkins proposed a framework that combines Rule-based Reasoning technology and RFID technology to track, schedule and intelligently handle incidents of waste movement.

The integration of these technologies with BIM offers many advantages in terms of facilitating location-based management, tracking of building materials and collecting remote data Chen et al.

BIM has been used in the building design stage to estimate the amount of demolition waste Kim et al. According to Won and Cheng , BIM offers great potential capacities in design review, 3D coordination, quantity take-off and phase planning for managing waste more efficiently throughout the project life cycle. Cheng and Ma developed a BIM-based system for demolition and renovation waste estimation and planning. This developed model poses the capability to deal with the estimates of the detailed volume information of each element category and material type, total inert, and non-inert demolition and renovation waste volumes, demolition and renovation waste-disposal charging fees and the total number of pick-up trucks for demolition and renovation waste.

Porwal and Hewage proposed a BIM-based analysis to minimise the waste rate of the structural reinforcement applicable for a two- storey reinforced concrete structure.

Blockchain technology creates a decentralised environment in which storage, operation, and control of the transactions do not rely on trusted third parties Yli-Huumo et al. Though BIM and Big data can be used as data communication technologies, Blockchain is the only technology where decentralised databases of records allow participants in the network to directly interact via a peer-to-peer network for information sharing and transaction of payments Turk and Klinc, According to Wang et al.

Further, the distributed nature of blockchain and its distinct features including a high level of trust, transparency, immutability, and traceability could help to address the issues related to the quality of historical waste data, reporting, and data management. However, the application of Blockchain in the construction industry, in general, has been limited and lack of studies exploring the role of Blockchain found in the WM stream Turk and Klinc, Blockchain can fundamentally change the traditional way of collecting, storing, replicating and tracing waste data at each movement of waste thus enabling the auditing of waste management performance while fulfilling waste-related compliances.

The framework contributes to the understanding of the potential capacities of each category of technologies in improving the process of WM in the construction sector. A good distribution of a wide range of smart technologies and ICTs have been adopted in several processes of SWM while the adoption is still at the prototype stage with limitations in CDWM.

The framework which outlined the potential application of technologies contributes to the understanding of how smart technologies could play effective roles in improving waste management processes in the construction sector. This study also explored the features of Blockchain, as a viable data management and transaction technology which can facilitate waste data management and trading of waste with improved operational efficiency, trust, and transparency while enabling the waste generators and waste consumers to connect without a trusted intermediary.
