The mechanical process applies various separation or sorting processes to recover materials for reuse from the municipal waste stream. Different mechanical processes include compaction, separation, classification, and size reduction. Size reduction is the process of transferring objects into smaller particles to increase their surface area. The classification process involves putting waste into different categories based on its material sizes. Both screening methods and air classifiers can be used during the classification process. The compaction process reduces the surface area of solid waste and also increases bulk. It is essential since it lowers the cost of storage and transportation of waste. The separation process isolates specific materials from a mixture of municipal waste. Separation ensures that some harmful materials such as metals are removed from the waste stream. No, my community does not take solid waste directly to a landfill. The law in my community requires solid waste to be separated into various categories such as plastic, glass, metal, paper, and mixed waste. The city has waste transfer stations where the trucks deposit the collected solid waste. Various wastes are collected separately and follow a different route to their final stop. Plastic, glass, metal, and paper waste are taken to the community recyclable handling facility. Other wastes are taken to waste-to-energy plants and used as a source of energy for the community. Non-recyclable waste is then loaded onto a train or a barge and transported about 500 miles to a landfill. Solid waste processing would be essential to my community due to the various advantages associated with it. For instance, the processing of solid waste before disposal in a landfill protects the environment and the community's health. Recycling waste would save my community from both water and air pollution. Therefore, I would recommend solid waste processing to my community.
