Relevance. Environmental pollution by waste is still one of the most pressing problems of the modern world. An important part of its solution is the proper waste sorting, which reduces the its volume, as well as simplifies its processing and disposal. Automatic waste sorting reduces the use of manual labor, as well as the possibility of infecting workers. Designing an automatic classification trash can solve the problem of waste sorting already at the stage of its generation, speeding up the process of neutralization. Aim. Automatically recognizing the waste material and then assigning the trash to the appropriate bins will be an important step towards a more sustainable and environmentally friendly waste management system. Methods. Development of an Arduino-based automatic waste sorting system. Using sensors, the Arduino processes the received data and sends a command to the executive device to move the waste to the appropriate container. Results and conclusions. Two prototypes of the waste sorting system were created. The first prototype was equipped with fewer sensors, which reduced its ability to accurately distinguish between waste types. After significant improvements, the work on the second prototype was deployed. This prototype is characterized by robust electronic processing and can function productively in all weather conditions due to its carefully designed housing. The relatively high accuracy in testing shows that the proposed model can sort waste efficiently, reducing manual labor and speeding up the recycling process. It has vital scientific significance and application value.
