Many recyclable materials consist of mixed materials that pose special problems. Discarded automobile oil filters contain steel, fiber, and contaminated petroleum. Oil filters are crushed and heated to remove oil, and the metal reclaimed. Discarded household appliances contain large amoxmts of steel but must often be dismantled, with other materials removed. A special fee is charged at recycling centers to discard most appliances. Fluorescent lamps contain small amounts of mercury that can be reclaimed. Used computers and television sets contain usable materials and, often, some toxic materials that can be collected for safe disposal. 

The small amounts of paint generated by the average household cannot be recycled economically, but most municipalities sponsor paint exchange programs and collect oil-based paints. Spent fuel rods from nuclear power plants can be recycled to reclaim unused uranium, and some spent uranium is used to produce armor-piercing bullets. Yard waste from households is often recycled and made into mulch for farming and gardening. Discarded Christmas trees are used to form mulch or are immersed in lakes as a habitat for fish.

Most great chemists are remembered for their research. Ira Remsen, although he contributed significantly to the research of his time, is one of the few chemists remembered mainly for his teaching and mentorship. It was under his leadership that American chemical research came of age in the late nineteenth and early twentieth centuries.
