Solid Waste

• Consists of all the unwanted undesired materials thrown into the dustbin
• It may be composed of biodegradable or non-biodegradable wastes.
• Open dumps used for disposing solid waste serves as breeding ground for rats and flies. Therefore, sanitary landfills are used as a substitute for these.
• Biodegradable wastes can be either aerobically on anaerobically broken down using microbes. The non-biodegradable waste can be recycled, reused, or dumped in landfills.
• Hospital wastes also contain hazardous materials, which have to be disposed properly. Hospital wastes are generally incinerated.
• Irreparable computers and other electronic goods make up e-wastes, which are either dumped in land fills or are incinerated. E-waste can be recycled also to recover metals such as copper, iron, silicon, gold, etc.
• To use the plastic waste in an efficient way, polyblend, a fine powder of recycled modified plastic, has been developed. When polyblend is mixed with bitumen, it can be used to lay roads with greater water repellent capacity and greater life.
