Japan focuses on CDW resource utilization. CDW in Japan is divided into three categories: industrial waste, construction waste and construction mixed waste, all crushed and screened, processed into recycled products, and used in different fields (Wang et al., 2015).
et al. believed that resource utilization could maximize the construction waste values and minimize the environmental impact of construction wastes by considering environmen-tal performance and transportation conditions (Ortiz et al. 2010). Chong et al. discussed the transportation energy con-sumption for construction waste recycling and the actual
Pricing decisions for construction and demolition waste recycling are severely hampered by consumer uncertainty in assessing the value of recycled building materials. This paper uses a construction and demolition waste (CDW) recycling utilization model that consists of a building materials manufacturer and a building materials remanufacturer and compares …
and makes it utilization effective. Key words: Resource optimization, Material Management, Delay in constructional projects, Stakeholders delay I. INTRODUCTION: Most of the construction industries focus on profits and time, in recent days 20% of construction industries were practicing effective resource management system along with proper
Phosphogypsum (PG) is a bulk industrial solid waste of wet-process phosphoric acid production. Every ton of phosphoric acid production generates as many as 4–6 tons of PG, including more than 90% of CaSO 4 ·2H 2 O, a small amount of phosphorus, fluorine, organic matter, oxides, heavy metals, radioactive substances and other impurities that have serious …
This study presents the first application of the pressure-state-response (PSR) model in the comprehensive assessment of construction and demolition waste (CDW) recycling benefits. Unlike traditional methods, the PSR model provides a multi-dimensional analysis that integrates economic, environmental, and social factors, offering a more holistic approach to …
1.2 The Great Harm of Construction Waste. First, the impact on the ecological environment. Construction waste in the pile, loading and unloading, transportation, landfill and other links, will have a negative effect on the surrounding air quality; construction waste in the open suburban site pile or landfill, after long-term rainwater erosion, groundwater infiltration …
The cement industry in Japan (Kawai and Osako 2012) has worked hard to maximize waste utilization. With no waste to be recycled in the cement industry, limestone consumption would have been 18% higher, clay consumption would have been 2,899% higher, and energy consumption would have been 22% higher.

Article 1 The purpose of this Act, in light of the circumstances in Japan, a country largely dependent on imports for major resources and where, along with the recent development of the national economy, the heavy use of resources generates an enormous amount of Used Products, etc. and By-products, a considerable part of which are disposed of while a …
the resource utilization rate in developed countries has been increasing under the joint promotion of the government and the market. In particular, in Japan, under the guidance of policies such as "reduction, reuse and recycling" of solid waste, the resource utilization rate of construction waste has reached 95.3% in 2018 (Zhang et al., 2022).
This Law aims at establishing a sound material-cycle economic system by; (i) enhancing measures for recycling goods and resources by implementing collection and recycling of used …
Japan has made a legislative commitment to achieve carbon neutrality by 2050. The construction industry in Japan contributes 30% of the carbon emissions and is the key sector for achieving carbon ...
11.3.1 The On-site Classification System of Construction Waste Needs to Be Strengthened. For construction waste, on-site sorting followed by transportation, treatment and resource recycling is the most efficient method. There is no mandatory on-site sorting system for construction waste, and on-site sorting is costly and less profitable, so the social …
