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.

The lack of stone material in the State of Amazonas and the possibility of using solid waste in the sublayers of pavements motivates the work in question, notably with the purpose of contributing as an alternative technical solution to the paving of the city of Iranduba / AM / BR. Compositions of soil mixed with waste from milled material (MM) and construction and demolition (CDW) were studied. The materials participating in the formulations were physically characterized, as well as the mechanical behavior of the natural soil (NS) and mixtures of soil-20% milled material (NS + 20MM) and soil-20% construction and demolition waste were determined. (NS + 20CDW). The results showed that the compositions with the participation of the milled material were the most efficient relative to the mixtures with the presence of the construction and demolition residue. It is noteworthy that both formulations, referring to natural soil, improved the expansion and presented an increase in the California Bearing Ratio, selection parameters for application in the base and subfloor layers.

Increasing building construction raises concerns about construction and demolition (C&D) waste management. To assess this issue the building components, the collection schemes, their recycling and disposal should be investigated. In order to manage C&D wastes, paying attention to how this kind of wastes is disposed is imperative for their correct identification. Inattention, lack of organization and proper transport and sanitary disposal of construction and demolition waste lead to problems such as accumulation of construction waste in the streets. However, more than 90 percent of the potential for recycling and re-using as raw materials is provided. Environmental Protection Agency (EPA) has classified C&D wastes into three categories: non-dangerous waste, hazardous wastes and semi-hazardous wastes. Currently in Tehran, an average of about 50,000 tons per day of construction and demolition wastes are produced from which over 30,000 tons per day are dumped in landfills. According to this research more than 57% of these wastes are placed in the first category (non-dangerous waste) and have the potential for being recycled and reused. On the other hand, items that are placed in the second category shall be managed based on the existing laws. This article provides some management solutions including proposing methods for collecting and reusing construction waste in accordance with current market needs in Iran.

The issue of sustainability has long been the subject of interest of the architecture engineering and construction sector. All three aspects of sustainability - economic, environmental and social - can be affected through appropriate construction waste management. Construction and demolition waste (CDW) is one of the largest worldwide waste streams, therefore it is given great attention by all stakeholders (investors, contractors, authorities, etc.). Researches have shown that one of the main barriers to insufficiency CDW recovery is inadequate policies and legal frameworks to manage CDW. It is also one of the EU's environmental priorities. Aim of the article is to confirm the economic potential of construction and demolition waste audit processing through case study. A pre-demolition waste audit has been processed for unused building of shopping center in the town Snina in Slovakia. Subsequently, a comparison of economic parameters (waste disposal costs and transport costs) of recommended CDW management was performed. This comparison confirmed the economic benefits of environmentally friendly construction waste management methods according to the waste audit results, which will also increase the sustainability of construction projects. In addition, the cost parameters of selected waste disposal methods could be another dimension of building information modelling.

The continuous rise in population, urbanization and expansion of cities has triggered a corresponding increase in construction and demolition activity. The frequent collapse of buildings attributed to poor structural design, building decay, and/or use of substandard materials has generated a substantial increase in construction refuse, also referred to as Construction and Demolition (C&D) Waste. This waste stream originates from residential, commercial, agricultural, institutional and industrial building projects for new builds, reconstruction, expansion, and refurbishments/rehabilitation. Most studies in Nigeria have generally focused on solid waste management without considering the uniqueness of C&D and giving it the attention needed, in order to achieve sustainable urban spaces that are highly functional, safe, convenient, and livable. This study seeks to investigate the different approaches and processes of C&D waste management in the City of Jos, in the Plateau State of Nigeria. The mix method was adopted for this research whereby quantitative and qualitative data was collected through a structured questionnaire for construction enterprises, as well as face-to-face interviews with the agencies responsible for waste management in the city. A total of 21 construction companies (representing about 10%) were randomly selected for questionnaire administration while interviews were conducted with the Plateau Environmental Protection and Sanitation Agency (PEPSA) and the Jos Metropolitan Development Board (JMDB) who are responsible for waste management. Investigations revealed that C&D waste consists of heavy and non-degradable materials such as: sheet metal roofing, sand, gravel, concrete, masonry, metal, and wood to mention only a few. The construction companies are solely responsible for: the collection, storage, transportation and disposal of wastes generated from their activities. Approximately 60-70% of the C&D waste materials are either reused, recycled or resold, while the remaining residual waste is indiscriminately disposed. Although the PEPSA and JMDB are responsible for waste management, their focus has been on establishing solid non-hazardous waste infrastructure systems, policies and plans. The absence of records of the quantity of C&D waste generated, the lack of financial data, and the omission of policies and plans for the C&D waste stream has resulted in a missed opportunity for a comprehensive and sustainable waste management strategy for the City and the state. To protect public health, valuable resources, and natural ecosystems, it is recommended that the C&D waste stream be included as part of the state’s waste management program, in consideration of the growing construction and demolition activity, by including C&D policies and guidelines.

AbstractConstruction and demolition waste generated in the Republic of Korea accounts for about half of the annual waste. The generation of construction waste is expected to increase gradually due to obsolete structures and reconstructions that have reached the end of their service life. Considering the geographical characteristics of Korea, where the land area is small and about 70% of which is mountainous, landfilling of waste is absolutely limited. Therefore, resource circulation such as recycling of construction waste is an urgent and important task. This paper overviews the current status of construction waste generation, treatment, and the flow of government policies in Korea. Furthermore, the current status, limitations, and stakeholder efforts regarding recycling of recycled aggregate from construction waste were reviewed. Data used in this paper were mostly collected from government reports, construction waste regulations, and research papers. The results show that construction waste management systems have been enacted and revised in line with social needs, and each stakeholder is making an effort to use the construction waste practically. The findings can provide valuable examples for countries that lack construction waste management systems. Graphic abstract

For environment protection in the European Union (EU) it is very important the construction waste to be recycled and reused. The potential for the construction waste recycling and reuse is high, as their components have high cost. There is an opportunity for re-use of such materials in road construction, for drainage systems, for outdoor sports grounds and other construction sites. In 2012 a regulation on the management of construction waste and on the use of recycled building materials was adopted in Bulgaria, aiming to introduce a new model for the management of construction waste. This would guarantee: creation of favorable legislative and economic conditions for implementation of technologies ensuring the achievement of recycling and recovery targets but which are also financially viable in line with the country's incomes; identifying the persons responsible for covering the costs of building waste management and achieving the recycling and recovery targets; creating conditions for the production and marketing of materials from recycling of construction waste at a price that is competitive with the same new raw materials used in construction. The main effect expected from this normative document is to contribute to Bulgaria's development towards European trends, environmental protection through an integrated framework for the management of construction and demolition waste that will reduce the harmful impacts on it caused by construction waste, improving the efficiency of resource use, increasing the responsibilities of pollutants and stimulating investment in waste management.

Improvement of building materials, optimization and development of technological processes of construction production require the development of promising areas of research to improve the efficiency of management of construction waste, which will provide economic and environmental benefits. The article provides statistical data on the volumes of formation and processing of construction and demolition waste, confirming the relevance and need for attention to the area of construction waste disposal. To improve the efficiency of construction and demolition waste management processes, it is proposed to create specialized centers that perform specific functions of coordinating material and information resources, which will track and coordinate the entire life cycle of waste from the source of education to the place of disposal or recycling. To improve the efficiency of processes for optimizing the management of construction waste, it is proposed to attract to them the organizational, economic and technological capabilities of private business.
