One of the environmental problems faced by people in the world is environmental pollution due to the general knowledge of the community about waste management. So that waste in the community does not accumulate, a special action is needed, namely recycling waste. The process of recycling waste is carried out differently according to its type. Organic waste can be recycled into compost or bio gas. Metal and non-metal inorganic waste can be recycled by means of reprinting, including printing or remelting without reducing the quality of the inorganic waste. In general, sorting waste is still done manually by hand. For example, to sort metal waste and non-metal waste from pile of garbage is still carried out by human hands manually. That matter less effective in terms of time and energy. With these conditions, one solution is to build a microcontroller implementation system Sorting Metal And Non-Metal Waste In The Trash.The process of sorting the types of waste consists of three categories, namely metal, plastic and glass waste. Garbage sorting is generally done manually, but this method is less effective, because it is a result of the general public about knowing the types of waste and still mixing waste into one place. Therefore, a smart trash can is needed that can sort automatically by utilizing microcontroller technology so that people do not need to sort manually. With these conditions, one solution is to build a microcontroller implementation system Sorting Waste in the Trash so that it can distinguish between plastic, metal and glass waste.
