Background Owing to the large amounts of energy greenhouse gases and waste that it generates the construction industry is fundamental to the transition towards a circular economy Indicators which show the circularity of products—and thus make them comparable with each other—can be used to support the implementation of such an economy In this article we
This paper provides an overview of literature on the multiple time recycling of concrete waste and meticulously analyzes the research findings The paper begins by reviewing the characteristics of recycled materials such as recycled coarse aggregate recycled fine aggregate and recycled powder obtained from concrete waste in relation to the recycling
Reducing waste from your construction projects can benefit your business in a number of ways Meeting construction waste legal requirements Reducing the amount of waste in your construction projects should make it easier to comply with waste legislation such as hazardous waste controls and your duty of care for business It should also help you meet other

Industrial Waste Water Meeting Discharge Standards Ratio of Standard Waste Water Discharged to the Total Discharge MAIN CONSTRUCTION INDICATORS OF DISTRICTS 2021 MAJOR ACCOUNTING INDICATORS OF CONSTRUCTION
A large number of papers focus on construction materials as main topics approached Zavadskas et al 2018 With the market increase for searching products with ecological and environmental characteristics building materials are the main issue as they are valued at the same price compared to standard products Kozicki et al 2018
Taking this context into account the aim of this article is to identify the indicators that address waste management in the main GBRS at the international level and in the specific case of Colombia and to analyse them from different points of view such as the stages of the life cycle of the building the waste hierarchy and the stages of the
It includes first identifying the mean value of frequency of waste occurrence according to respondents characteristics; second identifying the main predictive factors for waste occurrence based on latent relationships between initial waste factors; and third identifying the waste occurrence level indicator WOLI for the construction
The two main municipal waste categories at landfill are wastes from mechanical treatment of waste EWC code 19 12 12 and mixed municipal waste EWC code 20 03 01 which together make
Managing construction waste effectively ensures site safety eco friendliness and regulatory compliance Construction waste is a common issue This article explores different types of waste and offers advice on how to dispose of it responsibly Concrete and Rubble Waste Concrete is commonly used in construction for foundations walls and floors
Waste generation rate WGR has been broadly used as an indicator to measure CWM performance Bossink and Brouwers 1996 Mcdonald and Smithers 1998 Formoso et al 2002 Tam et al 2007 Lu et al 2011 It can be used as key performance indicators KPIs based on which contractors can benchmark their CWM performance and in turn identify the
The amount of concrete used in construction is twice as much as other building materials such as aluminium steel or wood The production of concrete annually is about 830Mt worldwide Mah et al 2018b Building and civil engineering works produces a massive amount of construction and demolition waste C&DW through the construction process and at the time of
GUIDELINES ON CONSTRUCTION WASTE MANAGEMENT SECTION 1 INTRODUCTION Construction Waste For the purposes of this guide Construction Waste is defined as materials that are unwanted or being generated during construction or demolition activities including improvement preparatory repair or alteration works
The development of sustainability assessment indicators has become a hot topic globally while sustainability practices are uncontrollably growing in the construction industry However the construction industry itself has negative impacts on the environment society and the economy Therefore during the construction phase the contractors who are responsible
It includes first identifying the mean value of frequency of waste occurrence according to respondents characteristics; second identifying the main predictive factors for waste occurrence based on latent relationships between initial waste factors; and third identifying the waste occurrence level indicator WOLI for the construction
Wood is renewable a carbon capturing sustainable structural material where a large amount of wood waste is generated each year Waste minimisation recovering valuables and retaining values within the closed loop supply chain is the key concept of a circular economy; however a very small amount of waste wood is recovered and circulated in the present
Circularity is finding its feet in construction Several Building Circularity Indicators BCIs have been developed to measure buildings Circular Economy CE potential but none of them has been standardized Currently the BCIs methodologies lack consensus on CE definition and scope Key Performance Indicators KPIs and various other technical aspects
The set of indicators covers waste from all economic sectors and from households but excludes some mineral waste types that arise in large quantities and originate mainly from the mining and the construction sector Table 1 illustrates the calculation of the waste management indicators and shows the results for theEUfor
• Construction and demolition is the biggest source of waste contributing to around a third of all waste in the EU in mass • Most construction and demolition waste can be easily recovered through recycling or backfilling • Data on construction and demolition waste are currently not sufficiently robust; this is particularly the case for
Purpose The built environment is a key sector for the transition towards a so called circular economy contributing to solve the global environmental challenges humanity is facing As buildings interact with other sectors like transport and energy a systemic approach is needed to assess the environmental relevance of circular economy practices The purpose of
The need to promote sustainability and reduce environmental effects has fueled a substantial increase in the use of recycled and waste materials in construction applications in recent years Concerns about harmful environmental threats are heightened when output increases and waste generation rises An economically viable solution to this problem could be
Recent studies have recognized material waste from construction projects as a serious problem for both economies and the environment This research aims to identify the major causes of material
