![]() ![]() This study proves that ultrasonic sensing is an effective approach in segregating plastic bottles, tin cans and paper cartons. It was concluded that the time difference is directly proportional to the distance and its value is affected by the thickness of the material. Using averaging in statistical analysis, a 15 cm working distance is implemented. For comparison purposes, the previous study about plastic bottle and tin can waste segregator using resonant frequency is based upon. Moreover, the system is standalone, which means that it does not need an LCD or a serial monitor to determine what type of material it detects, it automatically places the material on its correct bin by the use of servomotors. The system uses the principle of obtaining the time elapsed by ultrasonic sensing in determining the type of material to be segregated. This study has designed an electronic system that aids the user in sorting recyclable materials like plastic bottles, tin cans and paper cartons. Glass, paper, metal, plastic, tires, textiles and electronics are some of the common examples of recyclable materials. ![]() Recycling is one of the big steps in managing the waste system and could be one of the greatest solutions in maintaining a clean environment. From initial tests on this project, it is clear that the application of this system can aid in nurturing and developing a proper waste disposal culture within our society. Waste is either shredded or compressed and then stored prior to collection for recycling. The waste is carried along a conveyor belt to a sorting mechanism which redirects it to its material-specific processing section. The user information and material identity are communicated to the cloud database for user remuneration. An array of sensors at the inlet section identify the waste based on its material. The system identifies the user where necessary and receives the waste deposited by the user. This project offers a solution through a network of small-scale waste collection, sorting and processing machines and a universal rewarding system that encourages the society to properly dispose their waste. Despite clean up efforts by government and non-governmental organizations, reckless waste dumping continues to wreck havoc on our environment. ![]() With rapid urbanization and population growth, waste materials are everyday discarded aimlessly and their accumulation over time has led to a dirty and polluted environment. ![]()
