Description:TECHNICAL FIELD
[0001] The present disclosure, in general, relates to the technical field of waste management and recycling systems. In particular, it pertains to a simple, compact, and efficient sandsplash system for removing contaminants from polymer components, plastic waste, and Municipal Solid Waste (MSW).

BACKGROUND
[0002] Background description includes information that may be useful in understanding the present invention. It is not an admission that any of the information provided herein is prior art or relevant to the presently claimed invention, or that any publication specifically or implicitly referenced is prior art.
[0003] In the present scenario, the growing global population and rapid urbanization have led to a significant increase in the generation of Municipal Solid Waste (MSW). In India prospective, the annual production of MSW has surpassed 62 million metric tons, originating from various sources, including households, industries, and businesses. Unfortunately, a lack of awareness, combined with inadequate waste disposal systems, has resulted in the amalgamation of different waste types such as wet, dry, plastic, paper, metals, and glass, leading to the formation of towering waste heaps. Regrettably, existing water-based plastic waste cleaning systems exhibit limitations and inefficiencies, impeding the subsequent treatment, processing, cleaning, and recycling of plastic waste. This impediment hinders the seamless integration of plastic waste into the circular economy value addition chain.
[0004] In addition, the classification of Municipal Solid Waste includes both biodegradable and non-biodegradable waste, further categorized into recyclables and non-recyclables. The primary challenge may lie in the effective management of plastic waste, as current recycling methods face obstacles related to the inefficient removal of contaminants from plastic materials. The prevalent washing techniques employing water not only contribute to water contamination but also result in high energy consumption during the drying process. Moreover, these techniques prove ineffective in eliminating plastic waste from both floatable and non-floatable contaminants.
[0005] Further, as per the above mentioned, there may be an urgent need to provide an eco-friendly alternative that addresses the drawbacks associated with traditional approaches. Additionally, there may be a substantial imperative for sustainable plastic waste management, facilitating the dry cleaning of untreated plastic waste and rendering it recyclable for seamless integration into the circular economy chain.
[0006] There is, therefore, a requirement in the art to overcome the above-mentioned problems by providing a simple, compact, and efficient sandsplash system for removing contaminants from polymer components, plastic waste, and Municipal Solid Waste (MSW).
