The construction industry in Central Asia has shown rapid growth in the last decade due to an economic boom, leading to high construction & demolition waste (C&DW) generation accompanied by waste management operations falling behind worldwide best practices. The present study first employs a comprehensive environmental screening approach, PESTEL analysis, to identify and assess critical external and internal factors that can affect C&DW management in a leading Central Asian construction company (headquarters in Kazakhstan, the country with the largest economy in the region). Then, a case study is performed using 3R (reduce-reuse-recycle) principles and subjecting this company. Current international practices tailored to the given context are provided, existing company practices and applied improvements are discussed and prioritized improvements with implied sustainability benefits are proposed. The findings and recommendations are applicable especially to other construction companies operating in Central Asia that would ensure more sustainable C&DW management operations in the future.

Resumo Normas relacionadas à gestão de Resíduos de Construção Civil (RCC) estão vigentes no Brasil há mais de uma década. O intuito dessa gestão é amenizar os impactos ambientais decorrentes do gerenciamento indevido desses resíduos. O objetivo do presente trabalho é investigar a conformidade técnica e legal de sistemas de gerenciamento de resíduos de construção civil no município de Curitiba. Para tal, elaborou-se uma lista de verificação baseada nas normas em vigor e em alguns modelos de certificações ambientais, como: LEED, AQUA, CASBEE, BREAM e HQE. 24 obras de edifícios residenciais e comerciais foram  visitadas — com ou sem certificação ambiental. Essa lista de verificação foi aplicada nas construções, para realizar um diagnóstico do setor. Apesar da gestão de resíduos ser obrigatória e restritiva à obtenção dos certificados de conclusão de obra, os resultados da pesquisa demonstraram que há problemas na segregação, acondicionamento e transporte dos resíduos. Entretanto, a falta de conscientização e a aparente conformidade documental não se traduz em efetivo gerenciamento dos RCC. Palavras-chave: Resíduos de construção e demolição. Gestão de resíduos. Resíduos sólidos. Auditorias ambientais. Abstract Standards related to the management of Construction Waste (CW) have been in force in Brazil for more than a decade. The goal of this management is to alleviate the environmental impacts resulting from the poor management of these wastes. The objective of this work is to investigate the technical and legal compliance of construction waste management systems in the city of Curitiba. To this end, a checklist was drawn up based on current standards and on some models of environmental certifications, such as: LEED, AQUA, CASBEE, BREAM and HQE. 24 works of residential and commercial buildings were visited — with or without environmental certification.  A checklist was applied, in these buildings, to promote a diagnosis of the sector. Although waste management is mandatory and restrictive to obtain building completion certificates, the research results showed that there are problems in the segregation, packaging and transport of waste. However, the lack of awareness and the apparent documentary compliance does not translate into effective management of the CW. Keywords:  Construction and demolition waste. Waste management. Solid waste. Environmental audits. Resumen Normas relativas a la gestión de Residuos Sólidos de Construcción Civil (RCC) están vigentes en Brasil hace más de una década.

Construction and demolition waste (CDW), as the main consequence of construction and demolition (C&D) activities, has severely affected our sustainability needs. However, construction and demolition waste management (CDWM) lacks the integration of sustainability concepts. Thus, there is a great need to include sustainability dimensions in CDWM to reach sustainable construction and demolition waste management (SCDWM). This study aims at empirically investigating SCDWM by analyzing the impacts of factors that contribute to sustainability aspects of CDWM on waste management hierarchy (WMH), including reduce, reuse, recycle, and disposal strategies. According to the literature, 26 factors were initially identified and grouped under four categories, namely environmental, economic, social, and administrative, that contribute to sustainability aspects of CDWM. Subsequently, a pilot test was performed to assess the significance and applicability of these factors in the Malaysian construction industry by implementing the express analytic hierarchy process (EAHP). Then, a questionnaire survey was performed to collect data from 132 construction companies involved in CDWM. Partial least squares-structural equation modeling (PLS-SEM) was used to test the hypothetical relationships by applying SmartPLS software. Results demonstrated that the economic aspect of CDWM (main category) and “public environment contamination due to illegal waste dumping” (sub-category) were the most influential factor in SCDWM in Malaysia.

The rules and regulations on waste management in the construction and demolition sector are analyzed corresponding to the present scenario of C&DW in India. C&D waste from construction sites has emerged as a significant threat to India because of its severe footprint on the environment. Vast quantities of construction waste will have unfavorable consequences on the surroundings if they are not properly managed. Therefore it is necessary to manage the development of C&DW by the experts within the construction industry. The approach represented is specialized in rules and regulations on waste management so that the environmental impact of construction activities can be minimized.
