Waste (or wastes) are unwanted or unusable materials. Waste is any substance which is discarded after primary use, or is worthless, defective and of no use. A by-product by contrast is a joint product of relatively minor economic value. A waste product may become a by-product, joint product or resource through an invention that raises a waste product’s value above zero.
Examples include municipal solid waste (household trash/refuse), hazardous waste, wastewater (such as sewage, which contains bodily wastes (feces and urine) and surface runoff), radioactive waste, and others.
There is a long list of types of waste that our Society is producing at an enormous scale including the damages that they generate. They are polluting our seas, rivers, lakes, our soil and oura ir increasing mortal disease diffusion and representing a challenge.
We must be in a position where we can collect and recycle all our waste, clean up our planet and design solutions to avoid the casual disposal of waste but consider it as a resource and recycle it completely optimizing its utilization in products and systems.
