Development of metal-matrix composites from industrial/agricultural waste materials and their derivatives

Abstract

In this contribution, authors present a review on the state-of-the-art in the utilization of industrial and agricultural waste materials for the development of metal-matrix composites (MMCs), providing, through the judicious analysis of an ample and varied references source -from the oldest to the newest ones -, an insight into the challenges and opportunities for the exploitation to their full potential. In addition to its topicality, the novelty of this contribution lies in the presentation of key statistical, technical and property-related information of a comprehensive variety of waste materials classed into two main groups, namely, fly ash reinforced MMCs and MMCs derived from other waste materials. Although fly ash has been exploited in a broad range of applications, the attention paid for its use in the development of MMCs seems to be insufficient. A purposely designed chart helped to pinpoint the more demanding and profitable applications of fly ash, and establish strategic opportunity areas. With the exception of the recent utilization of fly ash for the automotive industry, virtually no other waste material has been reused for a specific industrial application. In this context, by identifying five reasons for this Downloaded by [University of Nebraska, Lincoln] at 08:41 26 August 2015 ACCEPTED MANUSCRIPT ACCEPTED MANUSCRIPT 2 observed delay, an essential goal of this review is arouse the interest of academicians, scientists/technologists and industrialists in the use of those materials for the fabrication of MMCs. In the case of agricultural materials, a two-fold perspective may apply, because while on the one hand, certain chemical elements have to be removed for specific applications, on the other hand, recovery of certain elements might be more attractive. Based on the significant progress observed so far, in terms of scientific and technological research, a promising future can be anticipated. The proper use of industrial and agricultural waste materials entails knowledge generation as a prerequisite for incubation of pilot-plant and industrialization stages, culminating with all related benefits to society.

Super absorbent, light, and highly flame retardant cellulose‐based aerogel crosslinked with citric acid

“…Current requirements encourage scientists to find sustainable alternatives to replace the present non‐regenerable sources in the material world. In recent times, agricultural wastes have been turned into various industrial products . One of the most common industrial raw materials is cellulose which is renewable, natural, organic, biocompatible, biodegradable resource, and has been regarded as a most promising replacement for the traditional materials .…”

Inspiration of reinforcements, manufacturing methods, and microstructural changes on wear behavior of metal matrix composites—a recent review

“…In this technique, the reinforcements are added in slurry stage of melt. It was also reported in other pieces of literature that this may be the suitable process route for Mg alloys which are highly reactive [26].…”

Waste Recycling in Thermoelectric Materials

“…In addition, many agricultural wastes also contain silica (SiO 2 ). [ 9,10 ] The recycling of scarce elements from spent TE materials or using waste from either industrial or agricultural origins in order to synthesis new TE compounds could reduce the need for raw materials, thereby minimizing costs, energy, and the human impact on the environment.…”
