Abstract

Manufacturing is a driving force for economic growth of a nation. During manufacturing, a lot of material gets wasted as scrap. The conventional methods used for waste treatment usually results in wastage of material, high energy consumption, large processing time, and may lead to formation of harmful gases. The use of microwave energy instead of conventional method has revolutionized the processing of materials significantly. The processes using microwave have short processing time, eliminating wastage of material, reducing pollution, and consumes energy less than the conventional processes. Along with these benefits, the quality of product is better due the property of uniform heating nature of microwave, so better microstructure of casting is achieved, the surface finish and defects in castings are less. Moreover, handling workshop wastes and their recycling is potentially dangerous and challenging, yet unavoidable job. The paper presents lead scrap collected from workshop, which is treated with microwave using a multimode applicator at 2.45 GHz. The principle of microwave hybrid heating is used, and silicon carbide susceptor is used to initiate coupling with lead. The samples were characterized using field emission scanning electron microscope (FE-SEM), X-Ray diffractometer, macro hardness tester.
