Most of the tungsten tailings (TTs) are filled in the open. As a result, the phenomenon that acid rain influences the engineering geological characteristics of tungsten tailings is impossible to avoid, especially in southern China, where acid rain occurs frequently. This work studied the...

Population growth, industrialization and technological advances have significantly increased waste production, waste collection, transportation and disposal induced significant costs. Waste could be considered a resource that allows nations to reduce the consumption of primary raw materials, protect...

The Coordinated management of solid waste dumps from different anthropogenic environments is important for pollution management of immediate and adjacent ecosystems. This study took three soil profile samples from three functional zones: the rural, the suburban, and the urban solid waste dumps. The...

The use of appropriate waste materials to stabilize problematic soils, such as expansive soils that are responsible for geotechnical damage, is a common practice in geotechnical engineering. This study presents the use of pulverized ash from the combustion of pine cone (PC) waste as a stabilizing...

Vermicomposting is a mesophilic biooxidation and stabilization process of organic materials that involves the joint action of earthworm and microorganism. An experiment was conducted to prepare vermicompost using partially decomposed organic waste such as MSW, fruit waste, vegetable waste and yard...

The rapid growth of infrastructure leads to industrial waste accumulation and natural resource depletion, raising the need for sustainable solutions. When zinc is refined, a significant amount of non-biodegradable material called jarosite (JS) is generated, requiring proper environmentally friendly...

Three laboratory scale systems were operated to study the anaerobic co-digestion of sewage sludge with the excess activated sludge and cattle manure which contained low COD concentration. The experiments were performed to evaluate the effects of different methods of pretreatment. Since the poor...

A Squeeze and Excitation Network is a deep-learning architectural component designed to enhance networks. The "squeeze" step reduces the spatial dimensions of the input feature maps, and the "excitation" step adaptively recalibrates channel-wise feature responses. This allows the network to focus on...

Compost stability is an essential parameter of composting. Recent studies have shown that the color of compost is influenced by the initial characteristics of the main organic substrates. In this study, the progression of CIELAB color variables and typical compost stability and maturity indices were...
