The World Green Building Council estimates that the construction industry accounts for more than 50 per cent of all materials extracted globally and that construction and demolition waste makes up 35 per cent of the world's landfills (Joseph et al., 2023).In 2020, China generated 2.6 billion tonnes of construction and demolition waste, but only 312 …

 — 1. Introduction. The construction industry has a profound effect on the environment, accounting for more than 50% of the exploitation of natural resources [1], such as coarse and fine aggregates, and is responsible for 39% of carbon dioxide (CO 2) emissions [2].To address this issue, researchers have explored alternative materials, …

 — The aim of this research was to evaluate the possibility of reusing waste foundry sands derived from the production of cast iron as a secondary raw material for the production of building materials obtained both by high-temperature (ceramic tiles and bricks) and room-temperature (binders such as geopolymers) consolidation. This approach can …

 — Waste foundry sand (WFS) is a by-product of the metal casting process, which constitutes a sustainable solution as a replacement for natural sand (NS) in the …

 — The presence of silica in waste sand obtained from foundry draws attention towards its use in civil engineering applications such as partial replacement or full replacement of fine aggregate in ...

 — GD has studied the history of the effects of using waste foundry sand in the production of construction materials and has also had a complete review in this field. MA …

June 2021 Since the beginning of the 21st century, the rapid development and urbanization in China has resulted in tens or even hundreds of millions of tons of Construction and Demolition (C&D) Waste produced each year. The boom in urban real estate has led to a soaring C&D waste disposal issue. Since 2017, the Chinese […]

 — 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.

 — Sand, gravel, and crushed stone (collectively referred to herein as aggregates) are the most in-demand materials on the planet in terms of volume. 1, 2 Together, they are a central foundation of our economies and integral to sectors such as construction, infrastructure, electronics, cosmetics, and pharmaceuticals. 3 The growing …

 — This study evaluates the stabilization of waste foundry sand (WFS) using an alkali-activated binder (AAB) produced from rice husk ash, hydrated eggshell lime, and sodium hydroxide.Mechanical properties, leaching behavior, and microstructure were assessed. The material's durability was investigated, and the impact of wetting-drying …

The charge to the Interagency Working Group that prepared this report is therefore both correspondingly simple and staggeringly complex: expand domestic mineral production in a timely manner to ensure that "our actions are conducted with strong environmental, sustainability, safety,

 — The production process could be divided into sand/gravel co-production process and separate produced sand process according to the processing methods of MS. In the practical project, it is recommended to give priority to the sand/gravel co-production process, which should be adjusted according to the changes of parent rock and the …

Construction waste (CW) in Chongqing is characterized by its variety, complex composition, large quantity, and significant environmental impact. With the help of the TSFM and …
