Increased construction activities in Australia have led to the generation of a massive volume of construction and demolition (C&D) waste annually. Management of this volume of waste requires an effective waste framework. The literature reported that the current Australian waste framework does not meet expectations and needs immediate improvements. This study was therefore conducted to seek the key C&D stakeholders' opinion about various issues identified in this waste stream. The specific objectives of this study are identification of the main barriers to effective C&D waste management, the impact of current regulations and opportunities to enhance the current C&D waste management system. A survey was conducted in 2019 to capture the stakeholders' perception. 132 participants from various industries and government agencies based in various Australian jurisdictions took part in the survey. The key results showed that the main barriers towards an effective management system are "overregulation, tough acceptance criteria, and increased testing requirements", "lack of local market" and "culture, poor education and low acceptance". Furthermore, a low number of participants indicated that the current legislation encourages waste recovery activities. The main areas of improvements included "providing a guideline that determines the accepted level of contamination for reusing C&D waste”, "preparation of guidelines on requirements of using recycled C&D materials in different industries" and "setting target for reduction, reusing, and recycling C&D waste". The results can inform policy development and be used as evidence for a broader discussion to solve lasting issues in C&D waste management.

During last few decades, construction and demolition waste has attracted great attention from practitioners and researchers, as well as governments in all over the world. It's obvious that construction and demolition waste and its control is very important in many aspects. In other hand, system dynamics is an empirical tool and waste management system is a dynamic system that needs to be studied and analyzed dynamically so that many misconceptions and problems in this area to be avoided. The main question is how we can manage and control waste management system to have a less amount of negative impacts on the environment and society. In order to answer this main question, this paper tries to represent a conceptual model called “cause and effect diagram” to have a general and typical understanding of waste management system especially in Ardabil city. Next, it represents Stock-Flow diagram that has capability of running in computer for further analyzing. Then, it simulates the model by POWERSIM software to analyze and optimize the dynamic model. The study indicated that increasing values of the variables including fines for illegal dumping, unit cost of landfilling, unit cost of collecting, unit cost of transportation and also developing waste management sites has implications of a low illegal waste dumping and a high amount of waste recycling and reuse.

PurposeThe literature shows that the current Australian waste management framework does not meet industry and government expectations. This study, therefore, seeks the key construction and demolition (C&D) stakeholders' insights on various issues identified. It aims to understand the main barriers to effective C&D waste management, examining the role of the federal government and exploring perceptions around waste regulations, policies and schemes.Design/methodology/approachAn online survey was conducted in 2019 to capture stakeholder perceptions. One hundred and thirty-two participants from various industries and government agencies representing Australian jurisdictions took part in the survey. Quantitative and qualitative data were collected.FindingsThe results show that the main barriers are “overregulation, tough acceptance criteria and increased testing requirements”, “lack of local market” and “culture, poor education and low acceptance”. The main areas of improvement include “providing a guideline that determines the accepted level of contamination for reusing C&D waste”, “preparation of guidelines on requirements of using recycled C&D materials in different industries” and “setting a target for reduction, reusing and recycling C&D waste”.Research limitations/implicationsSome research findings may not be generalisable beyond Australia, but there are interesting insights for an international audience. The results inform policy development within the Australian states and territories context, to support the design and implementation of a circular economy model in the construction industry. The findings are evidence for a broader discussion to solve prevailing issues in C&D waste management, notably in the context of construction materials' end of life management.Practical implicationsThe study highlights that policy development needs to be further expanded to include new/current waste management schemes including manufacturer's shared responsibility of waste generation, subsidies for C&D waste recycled materials and the proximity principle.Originality/valueThis paper provides a clear insight into C&D waste management stakeholders' perceptions towards the current waste management system in Australia.

The article is devoted to the consideration of actual problems of the waste management system – a part of the closed-cycle economy. It is argued that a competent approach to solving these problems will help not only to modernize the Russian economy, but also to achieve other national goals.

Russia is just starting to become a circular and green economy. The development of an efficient national waste management system is a prerequisite for the circular economy (CE). Russian companies are already moving toward adopting more circular business models because it is proven to be a sound business strategy. This strategy facilitates access to new markets, drives innovative solutions, and saves production costs. This paper presents a general understanding of the CE concept. Using practical examples, we show how the Russian government and other stakeholders are providing solutions to advance the development of the waste management system. The paper demonstrates political, legal, and institutional changes implemented through waste management practices and reforms. We introduce four stages of evolution of waste management in Russia and discuss the changing roles of stakeholders in a waste management ecosystem. We conduct a case study of the best available techniques of waste management in leading Russian companies to identify the roles existing in waste management systems (WMS), to allocate responsibilities of each role, and to describe three types of corporate strategies of waste management. The paper is based on the analysis of official public documents and official reports of leading Russian companies.
