Many recycling bins are designed to be easily recognizable, and are marked with slogans promoting recycling on a blue or green background along with the universal recycling symbol. Others are intentionally unobtrusive. Bins are sometimes in different colors so that user may differentiate between the types of materials to be placed in them. While there is no universal standard, the color blue is commonly used to indicate a bin is for recycling in public settings.
Recycling bins or cans, or carts are a common element of municipal kerbside collection programs, which frequently distribute the bins to encourage participation.
