Circular Economy of Dharavi

As developing nations continue to progress, people of these countries face problems of shortages in building materials and rising production of solid waste. The purpose of this research study is to explore the potential of establishing a circular economy by recycling/reusing solid waste as alternative building materials. Focused on the slum of Dharavi in Mumbai, a settlement well-known for its existing recycling business, this article explores the concept of a circular economy utilizing local informal labor by considering the flow of waste materials in the slum. This article presents an analysis of the case studies where waste is reused as a building product and identifies the gaps, advantages, and disadvantages related to how and where the building materials from the case studies could be adapted in the context of the Dharavi slum.

High Temperature Processing

At present, processing and recycling of municipal solid waste (MSW) has become more relevant in our country and the world at large. This problem concerns large towns and cities, where every year millions of tons of all kinds of fractions of household waste are produced. Disposal or recycling of solid waste is an environmental issue, but it is associated with the solution of complex technical, energy and economic challenges. The purpose of this study is to identify the advantages and disadvantages of modern methods of processing and disposal of MSW with the prospect of developing and creating a device for recycling MSW taking into account modern approaches to energy saving and environmental protection. The main results of the study are to create a simple, reliable and technically sound method of MSW disposal to obtain additional energy. The significance of the results obtained for the construction industry is the design of a device for the disposal of solid waste with the production of solid combustion products and further their use as building materials and products for various purposes. Because of the technological process of MSW processing, it becomes possible to generate some returns through use of resulting thermal energy for electricity production.

Heritage Buildings

With the development of a modern designer's workshop, various smart city issues have to be included in line with more conventional analyses. Presently, we also face emerging circular economy theme, which has a high impact not just on the introduction of circular loops into the flow of building materials, but also on the design approach and management choices. Historic heritage buildings should also be considered within this new theme. Most of the existing research either deals with new or modernized buildings, or with the re-use flows of various materials, often coming from historic buildings gone outside the limits of repair. This chapter explains the proposed approach and includes case studies where such an approach has been provided.

ABSTRACT The following study is based on the comparison of the actual transition processes in Estonia and Slovenia in 1991-2000 with the aim of testing two conceptual models (shock therapy versus gradualism) of transition theory in practice. This article has two main goals, closely interlinked with each other. The first task is to analyse whether the reform paths undertaken by Estonia and Slovenia followed the theoretical concepts of 'shock therapy' and 'gradualism', the models the states are often symbolising in theoretical debates. The second task is to evaluate the ability of the theoretical models to correctly allocate the classical country examples to the shock therapy and gradualist models. This research study is also interested in what are the advantages and disadvantages of a polarised approach to transition theory models and how these models can be improved.

Waste Minimisation

A circular economy requires closed circuits of consumed resources. Construction generates approximately 50% of solid waste globally, which is difficult to manage. The aim of this article was to identify the factors that determine the development of circular construction in the context of waste minimisation in the life cycle of building structures. The identification of cause-and-effect relationships by means of the DEMATEL method allows the problems of construction waste management to be taken into account in the context of the development of sustainable construction and fulfilling the principles of the circular economy.
