Population growth, consumerism and linear (take-make-dispose) economy models have been piling up waste for decades. The construction industry is also based primarily on linear economy models, but the good news is that most of the waste can be re-used or recycled. So far, numerous models for managing construction and demolition waste in a sustainable way have been developed, but only a few models have included circular economy approaches. The main objective of this study is to propose an integrated framework for the sustainability assessment of CDW management. Apart from the economic, environmental and social aspects of sustainability, this model also includes circular economy principles. The proposed framework is based on the integration of existing methods: bottom-up materials stock approximation; cost–benefit analysis for criteria calculation; and scenario and multi-criteria decision-making analysis for sustainability. It is suggested that the European average recovery rates should be used for future scenario development. With higher re-use and recycling rates, the potential for the circularity of the recovered waste grows. In an effort to increase circularity in the region, particular attention was devoted to customize the framework and examine its potential for use in the Western Balkan countries. The framework may also be useful in countries with immature construction and demolition waste management.

In the world, around 30% of the total solid waste is construction and demolition waste. In India, as per the building material promotion council, 150 million tonnes of C&D waste is generated every year. In the total C&D waste, only one percent which is 6500 tonnes per day is recycled, mentioned in the report released by the Centre for science and environment, New Delhi. There is a rising gap between increasing demand and limited sources in the construction sector of India. It leads to market instability and environmental harm. Linear business model is most commonly used in present times. It is one of the main reasons for the increase of C&D wastes. This linear approach (source-commodity-waste) encourages the one-use of products. It leads to excessive dumping of C&D wastes in landfills, which is not a sustainable practice. Circular business models leads to closed-loop approach (source-commodity-waste-new source). The adoption of circular business models in C&D waste management is the possible solution for the decreasing resources. This study aims to discuss the implementation of various approaches including conceptual models, methods, and tools of circular business models in the C&D waste management in India, which leads to the circular economy and sustainable development. Through the study of recent literature sources, various data related to circular business models, circular economy are collected. Data analysis will be done using the literature review. This research will highlight the socio-economic, environmental benefits, improvements, and the applicability of circular business models in the C&D waste management of India. This paper is concluded that framing strict circular economy policies for India would encourage the implementation of CBM in C&D waste management which reduces the need for fresh resources and ensures sustainable development.

Abstract The construction sector plays a crucial role in the transition to a circular economy and a more sustainable society. With this objective in mind, Flanders – the Dutch speaking part of Belgium – makes use of a traceability procedure for construction and demolition waste in order to guarantee that value can be derived from downstream waste processing activities. This article takes this traceability procedure as a legal case study and examines if the use of blockchain technology could lead to even stronger supply chains, better data management, and, more generally, a smoother transition to circular practices in the construction sector.
