Chapter 7 Challenges in green waste-reinforced aluminum composites

Abstract

This chapter presents the state of the art in utilizing industrial wastes, animal wastes, household wastes, and agriculture wastes as reinforcement in metal matrix composites (MMCs). In this way, a sustainable solution can be provided to reduce pollution and hazardous wastes from the environment. This work provides insight into the enormous challenges in the development of defect-free MMCs. The reinforcement materials from three categories such as industrial, agriculture, and animals are considered in this chapter. Among all waste residues having potential as reinforcement in MMCs, fly ash has been utilized at industrial scale. Although a wide range of applications of fly ash are available, they seem to be insignificant. Still there is huge potential for further research and development of MMCs with fly ash. Apart from this, none of the waste residues mentioned in this chapter have been utilized significantly at industrial scale. In order to properly utilize the waste residues from industry, agriculture, animals, and household, necessary knowledge creation is the precondition to reach the industrialization stage. However, on the basis of considerable progress in technological and scientific research, a better future in this area can be anticipated.
