Zero waste or Zero Waste (Zero Waste) is a waste management strategy that aims to redesign the cyclical life of waste considered not as waste but resources to be reused as second raw materials, contrast with practices that necessarily involve incineration or landfill processes, and tending to significantly cancel or decrease the amount of waste to be disposed of. The process is based on the pattern of reuse of resources present in nature.
Among its greatest theorists is Prof.. Paul Connett, professor emeritus of st. Lawrence University.
