Effect of zinc industrial waste on the mechanical and microstructural properties of the ternary blended concrete

Elavenil Solaiyan et al. View all

Issue 3

Solid Waste Management

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...

Sustainable use of ferrochrome slag and quarry dust composites as cement-bound layers of flexible pavement

Ajay Chappa et al. View all

Issue 3

Solid Waste Management

In this study, an attempt was made to characterize ferrochrome slag as cement-bound layers of flexible pavement in view of its leaching behavior. Toxicity Characteristic Leaching Procedure (TCLP) test was conducted to assess the mobility of toxic elements in ferrochrome slag. Ferrochrome slag...

A Deep Learning-Based Buffalo Optimizer based Squeeze and Excitation Network for Garbage Classification for a Sustainable Environment

Subhashini R et al. View all

Issue 3

Solid Waste Management

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...
