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.

The problems arising from construction and demolition waste have always been in our country. The civil construction industry is the sector that generates the most waste that impacts society and is the one that consumes the most raw materials. As a result, it is necessary and extremely important that there is a sustainable management of construction waste. The irregular dispositions of these residues cause many negative impacts to the environment, since they are often thrown in vacant lots, permanent preservation areas, roads and public places, harming the quality of life of the population. Recycling can generate a significant economic advantage in relation to the final destination both in regular deposits and mainly in relation to the irregular ones that cause so much damage to the environment. This study sought to collect information on the current situation on construction waste. And in order to be developed, the present work used bibliographic research in books, specialized magazines, periodicals, and electronic media. Concluding in the final considerations, in which vital points of the research are presented followed by the stimulations the continuity of the studies and the reflections on the generation of solid residues in the civil construction.

Abstract The need for better natural resource use is currently increasingly recognised, and high emphasis is given to the circularity of building materials and the reduction of activities with negative environmental impact. Legislation, guidelines, and other documentation play an important role in improving demolition activities and construction and demolition waste (CDW) management. Good practices in CDW handling is not achievable without knowledge about CDW recovery techniques described in guidelines and other documents. Demolition activities in arctic regions could be more challenging due to harsh climate conditions, and therefore the cooperation between Russia, Norway and Finland was established to boost the uptake of good practices in demolition activities and CDW management. The main subject of this article is an overview of presently used demolition practices, CDW management, and verification of areas where practices with lower environmental impact and increase of material circularity could be utilised. Two fundamental documents, namely “EU Construction & Demolition Waste Management Protocol” and “Guidelines for the waste audits before demolition and renovation works of buildings” [1, 2], were published by the European Union (EU) in 2019 and serve as a foundation for changes in demolition activities and CDW management in EU and adventitiously also in the Russian Federation and Norway.

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.

Natural Aggregate

Currently, a number of disadvantages hampers the use of recycled concrete aggregates (RCA). The current review proves that concretes made with complete replacement of natural aggregate with RCA allow the production of high-quality concrete. One of the possibilities for improving concrete properties with RCA is the use of extended curing and pozzolanic materials with varying cement ratios. The potential use of RCA concretes is in the production of high-value materials that increase environmental and financial benefits. RCA have strong potential in the development of a new generation of concrete and stimulate economic activity in many countries in addition to optimizing natural resources. Economic benefits include minimal travel costs; cheaper sources of concrete than newly mined aggregates; reduction of the landfill area required for the placement of concrete waste; the use of RCA minimizes the need for gravel extraction, etc. The proposed strategy could be to sequentially separate demolition waste such as roof finishes, waterproof materials, interior and exterior materials, etc. Closing life cycles is the main approach used for efficient structures for the recycling and reuse of construction and demolition waste in the production and recovery of materials, especially when recycling and reusing materials. In the life cycle, the recycling of recovered materials allows them to be used for new construction purposes, avoiding the use of natural concrete aggregates. Government, design institutes, construction departments and project managers should be involved in the creation and use of RCA. In demolition and construction, the main players are the project owners. Their obligations, expectations and responsibilities must be properly aligned. For the past 20 years, recycled concrete aggregate from demolition and construction waste has been considered as an alternative to pure concrete in structural concrete to minimize the environmental impact of construction waste and demolition waste and the conversion of natural aggregate resources. It is now recognized that the use of RCA for the generations of concrete is a promising and very attractive technology for reducing the environmental impact of the construction sector and conserving natural resources. In the market, the selling price is not an obstacle for market applications of RCA, as there are scenarios in which their cost is lower than the cost of products made from conventional building materials. This is more of an acceptance factor in the market for recycled concrete aggregates. In this sector, the lack of identification, accreditation and uniform quality certification systems and their narrow application cause some marketing problems. With proper RCA preparation, concrete with standard physical and mechanical properties and performance characteristics can be obtained.

Abstract The construction industry has been greatly developed in the past few decades, especially in the extensive use of underground space. The increasing amount of waste (e.g., soil, sludge, and rock) generated in the underground construction constitutes an important part of construction and demolition waste (CDW) but the related problems are rarely addressed in an independent quantitative study. In order to facilitate recycling of underground construction waste (UCW), quantitative methods for predicting UCW are proposed based on mass conservation in this study. Through on-site investigation and literature review, the source characteristics of UCW and corresponding recycling potential are firstly analyzed. Secondly, the corresponding quantitative mothed is proposed for predicting each type of UCW according to the principle of mass conservation. Finally, the proposed quantitative methods are applied in two real underground infrastructure projects to verify the accuracy. The results show that the accuracy of quantitative methods for predicting shield sludge and engineering soil is 82.03%-95.79% and 94.49% respectively. In addition, detailed geological and geotechnical analysis is the key to accurate management of waste generated in underground civil and infrastructure projects. In both cases, underground construction produced a large amount of construction waste with great recycling potential. UCW can theoretically reach 100% recycling, and full reuse and recycling of UCW will bring huge economic value and be conducive to the sustainable development of the construction industry.
