The European Commission considers construction and demolition waste (C&DW) as a priority waste stream because of the large amounts generated [1–4] and its high potential for reuse and recycling embodied in the composition of the waste [5, 6].Specific legislation for C&DW has been developed in Europe such as the Directive 2008/98/EC on …

This study collected basic information and conducted waste composition surveys to identify the present management condition of construction and demolition waste (CDW) landfills in Hanoi of Vietnam and to characterize waste composition and grain size distribution of CDW dumped at landfills. Basic information on seven CDW landfills under operation or …
Definition of C&DW. C&DW term is defined as the solid waste generated from CRD works, such as land excavation or foundation, civil and building construction, site cleaning, demolition events, roadwork, and building renovation, which are the main causes of C&DW generation [35,36,37,38,39].Tchobanoglous et al. [] stated that demolition wastes are …

In order to have adequate record of waste and then develop tools for waste reduction, there is a need to identify the sources of waste and assess their impacts on project outcomes [].Despite the fact that considerable research efforts have been done for the identification of the sources of construction waste, there is a need for research targeting the …
Source reduction reduces life-cycle material use, energy use and waste generation. EPA gives it the highest priority for addressing solid waste issues. While reuse and recycling are important methods to sustainably manage waste once waste has already been generated, source reduction prevents waste from being generated in the first place.
It was seen that the average composition of waste generated on site is mostly concrete and ceramic materials. A global C&DW ... Through a deep analysis of 18 building projects, the model developed is able to estimate C&DW quantities (in volume) by introducing in the model the following information: apartment floor plan/floor; construction ...
The construction and demolition (C&D) waste generated by the Canadian construction industry accounts for 27 % of the total municipal solid waste disposed in landfills. However, it is evident that over 75 % of what the construction industry generates as waste has a residual value, and therefore could be recycled, salvaged and/or reused. The need for …
Food Waste Generation and Composition Study Analysis 2022 3 EXECUTIVE SUMMARY The Minnesota Pollution Control Agency (MPCA) contracted with Resource Recycling Systems (RRS) and GRG Analysis to measure the proportion of food in Minnesota's Mixed Municipal Solid Waste (MMSW), including residential and commercial streams.
The United States Environmental Protection Agency (USEPA) is considering the addition of construction and demolition (C&D) waste to its municipal solid waste (MSW) characterization …
Disposing of potentially recyclable materials and items generally represents a significant portion of a builder's budget. Becoming aware of …
Franklin Associates (1998) and USEPA (2009) estimated the amount of C&D debris generated in the US using an approach similar to the waste-weight-per-construction-area method reported by Yost and Halstead (1996) to calculate the amount of drywall generated in a specified region. Eqs. (1), (2) show this method, which uses some measure of the level of …
Based on the volume of waste generated, its composition, and how it is managed, it is estimated that 1.6 billion tonnes of carbon dioxide (CO2) equivalent greenhouse gas emissions were generated from solid waste …
The Composition of Waste at the Kerbside in 2021-23 describes what s throw away and recycle, to highlight the opportunities for further waste prevention, recycling and diversion from landfill.. As well as an analysis of residual waste, which is the bin that should be used to dispose of waste that cannot be recycled, the report also presents a …
The global market for construction aggregates is expected to increase 5.2% this year, and again next year, up to 48.3 billion tonnes [1].In the United States, the Environmental Protection Agency [2] estimated that the generation of debris, from the construction, demolition, and renovation of residential and non-residential buildings in 2003, was close to 170 million …
Overall, the historical waste composition results in this section demonstrate that waste composition in 2020 was an outlier, and that 2021 waste composition and generation tended to be more similar to 2018 data than 2020 data. Overall, waste composition in 2018 and 2021 was very similar. Slightly more plastic and compostable organics was ...
This study focuses on the composition, microstructure, and formation mechanism of construction waste, and the research conclusions are as follows: (1) The mineral compositions of RA and …
For the construction waste with significant or more pollution, the potential environmental impact on the surrounding surface water was preliminarily judged through leaching toxicity analysis and anion content analysis. For the construction waste with environmental pollution risk, by judging its XRD phase composition, combined with the ternary ...
The basis of this study is to perform a comprehensive literature review of construction and demolition waste including the generated amounts, composition, the …
Waste composition analysis is the systematic study of the types and quantities of materials found in waste streams. This process helps in understanding what is being discarded, enabling more effective waste management strategies and supporting the transition towards zero waste initiatives by identifying potential areas for reduction, reuse, and recycling.
The analysis of the construction waste composition and mix formation mechanism is of great help to better study the macromechanical properties of RA and road performance. Zhe Li used IPP software to identify CT scan images of construction waste-recycled mixes and analyzed recycled mixtures' microscopic particle morphology and particle contact ...
The composition of the C&D waste is dependent upon the type of structure and region of study. ... [34] employed a combination of lifetime analysis and waste generation calculation method, where information on the population, per capita floor area, age and lifetime of buildings, and appropriate assumptions were used in estimating the present and ...
Recycling of construction waste has been a hot issue in road engineering research, and microscopic characteristics and composition of construction waste-recycled aggregate (RA) significantly influence their macroscopic service characteristics.
