To safely dispose of different types of waste, first, segregate them into categories: recyclables (like paper, plastic, and glass), organic waste (food scraps), hazardous waste (batteries, chemicals), and general trash. Recyclables should be cleaned and placed in designated recycling bins, while organic waste can be composted or placed in green waste bins. Hazardous waste must be taken to specialized collection points or events, following local regulations. General trash can be placed in standard waste bins, ensuring that all items are securely bagged to prevent leaks or spills.

As of 2021, the United States has produced approximately 90,000 metric tons of spent nuclear fuel, which is the primary form of radioactive waste from nuclear reactors. In terms of volume, this waste occupies about 1,000 cubic meters. Most of this spent fuel is stored on-site at nuclear power plants in pools or dry cask storage systems. The management and disposal of this waste remain ongoing challenges for the nuclear industry.

People began dumping nuclear waste in the ocean in the late 1940s, with significant activities occurring throughout the 1950s and 1960s. This practice was largely a result of the lack of effective disposal methods at the time. However, increasing environmental concerns and awareness led to a ban on ocean dumping of radioactive waste, which was established by the 1972 London Convention.

Taking a piano apart for scrap metal can be labor-intensive and may not yield significant financial returns, as the value of the metal often doesn't justify the effort involved.
