Black cotton soils, which are expansive, are present in abundance in Ethiopia. This type of soil possesses expansion when saturated with water and contraction during hot seasons, due to which it is labelled as “weak soil.” They may remain a threat to the structures if they are constructed over them without precautions. The quality of such soils can be improved by treating them with suitable stabilizers or soil reinforcers. This paper discusses the chances of using the second waste of plastic bottles as a reinforcer to strengthen weak black cotton soils in Ethiopia. Second, plastic bottle waste was added at 1%, 2%, 3%, 5%, 7%, and 9% to the soil, and numerous trials were conducted to ensure the reliability of the results. The effects were analyzed based on the results from the Atterberg limit tests, compaction tests, unconfined compression strength (UCS) tests, and the California bearing ratio test (CBR) for soaked and unsoaked conditions. The results were compared against the natural soil results, and the optimum usage percentage of second waste plastic required to reinforce the soil was reported. The results indicate that among the various properties used, the mix with 2% second waste plastic is effective with numerous trials being conducted to ensure the reliability of the results and decreased values of OMC by 18.5%, increased MDD by 1.9%, increased CBR by 50.9%, and increased UCS by 10.1%. Thus, the research provides a novel technique to recycle plastic waste once again as soil reinforcement, thereby saving the environment from dumped waste.

In order to improve the comprehensive utilization rate of industrial solid waste and the road quality, a novel low-carbon and environmental friendly soil stabilizer is proposed. In this study, steel slag (SS), carbide slag (CS), blast furnace slag (BFS), fly ash (FA), and desulfurized gypsum (DG) were used as raw materials to develop a multiple industrial solid waste-based soil stabilizer (MSWSS). The optimal mix ratio of the raw materials determined by D-optimal design was as follows: 5% SS, 50% CS, 15% BFS, 15% DG, and 15% FA. The 7-day unconfined compressive strength (UCS) of MSWSS-stabilized soil was 1.7 MPa, which was 36% higher than stabilization with ordinary portland cement (OPC) and met the construction requirements of highways. After 7 days of curing, the UCS of MSWSS-stabilized soil was significantly higher than that in the OPC group. X-ray powder diffraction (XRD), thermogravimetric analysis (TGA), and scanning electron microscopy (SEM) analysis indicated that the prominent hydration products were ettringite (AFt) and C-S-H gel. The results showed that an amount of AFt and C-S-H were formed in the initial stage of curing, resulting in a rapid improvement in early UCS. As the curing proceeded, the content of AFt and C-S-H increased constantly and grew intertwined with each other, which lead to the denser microstructure of stabilized soil and better mechanical strength.

“…Moreover, the improper disposal of e-waste leads to the loss of valuable and recoverable raw materials, including precious metals and rare earth elements, worth billions of dollars [4]. To address these challenges, there is a pressing need for a comprehensive and sustainable approach to managing e-waste [5]. The circular economy model, which aims to reduce, reuse, and sustainably dispose of end-of-life products, provides a promising framework [6].…”

The growing generation of E-Waste has forced the various environmental agencies of the world to studies about the serious problematic trends of generation, uses, management and about the discarded part of E-Waste. This problem also grabs attention of many researchers of the world to know about the different aspects of E-Waste generation in such a rapid rate. Some of them discover new ways of handling this electronic waste which contains hazardous and some precious metals in it. This research paper delves into the global challenges posed by electronic waste (e-waste) and explores opportunities for sustainable management. The study underscores the pressing need for responsible recycling strategies, advocating the circular economy model as a viable framework. It provides a detailed examination of India's burgeoning e-waste generation, regulatory measures, and the imperative for effective enforcement. The paper explores mechanical methods for e-waste processing, considering efficiency, economic implications, and the life cycle assessment of e-waste. Practical applications of e-waste in civil engineering, from construction materials to artistic installations, are outlined. Ultimately, the research emphasizes the urgency of collaborative efforts among governments, industries, and individuals to establish robust infrastructure and practices for responsible e-waste management, weighing economic advantages against potential environmental hazards associated with recycling.
