AI Article Synopsis
- Construction and demolition waste in Europe generates about 500 million tonnes annually, with a significant portion ending up in landfills, especially in countries like Spain.
- Most of the waste is only partially processed for recycling, particularly recycled aggregates, which have not seen much commercial success.
- The study aims to utilize a new tool, LABWASTE.14, to assess the economic feasibility of using recycled aggregates from inert waste in various landfill phases, potentially decreasing reliance on quarried aggregates.
Article Abstract
Waste from construction and demolition activities represents one of the highest volumes of waste in Europe. 500 million tonnes are produced throughout the whole EU every year. In some EU members like Spain, approximately 83 per cent of such waste is disposed in landfills. The remaining part is classified and processed in treatment facilities so that it can later be used as recycled aggregates in the construction sector (sand, gravel, aggregates, etc.) but without much commercial success. The aim of this study is to use recycled aggregates from inert wastes (IW) in the different phases of a landfill (construction, operation and closure) with the aid of a new computer tool called LABWASTE.14. This tool incorporates the mathematical relationship among the activities of the landfill and provides as a result the economic viability of using recycled aggregates compared to aggregates from quarries. Therefore, knowing the needs of aggregates in landfills (dams, drainage layers, covering layers, collection wells, etc.) may determine the amount of IW that could be recovered. These calculations can be obtained from some of the data that is introduced (population, land physiography, etc.). Furthermore, the use of LABWASTE.14 makes it possible to reduce the demand for aggregates from quarries.

Hg is highly toxic and can cause serious harm to the environment and humans. Thus, it is vital to develop efficient Hg sensors. In this work, a LMOF-based (LMOF = luminescent metal-organic framework) "turn-on" Hg sensor () is first developed by an aggregation-induced emission (AIE) functional ligand.

Promoting soil structure is considered an essential prerequisite for abandoned mine land restoration. Sewage sludge (SS) has the potential to improve soil structure. However, traditional SS application to improve soil structure requires a lot of SS, potentially exacerbating heavy metal (HM) contamination.

In order to study the effect of the crushing process on the fine separation of reclaimed asphalt pavement (RAP) and the mechanical properties of cement-stabilised aggregate mixed with RAP, four crushing processes, namely small mesh hammer crushing, hammer crushing, jaw crushing, and double roller crushing, were used to separate the aggregate from asphalt in RAP materials. The effect of crushing on the grading characteristics and agglomeration condition of RAP material was investigated. RAP cement-stabilised aggregates were prepared and analysed for their mechanical properties and micro-morphology using RAP materials obtained from fine separation.

The evaluation of the mechanical performance of fly ash-recycled mortar (FARM) is a necessary condition to ensure the efficient utilization of recycled fine aggregates. This article describes the design of nine mix proportions of FARMs with a low water/cement ratio and screens six mix proportions with reasonable flowability. The compressive strengths of FARMs were tested, and the influence of the water/cement ratio (/) and age on the compressive strength was analyzed.

The application of recycled concrete aggregates (RCAs) has become increasingly popular for different types of structures, as presented in several studies. However, depending on the type of structure and the region, RCAs might have different properties. This study aims to investigate the application of RCAs of different origins for substructure layers of the cycle paths located in Central Europe, which was not analysed previously.
