Proteins are broken down by proteases, bilirubin is broken down by the liver, and iron is broken down by macrophages in the liver and spleen.
Iron(III) sulfide (Fe2S3) breaks down into iron(III) oxide (Fe2O3) and sulfur dioxide (SO2).
Old or damaged RBCs are removed from the circulation by macrophages in the spleen and liver, and the hemoglobin they contain is broken down into heme and globin. The globin protein may be recycled, or broken down further to its constituent amino acids, which may be recycled or metabolized. The heme contains precious iron that is conserved and reused in the synthesis of new hemoglobin molecules. During its metabolism, heme is converted to bilirubin, a yellow pigment that can discolor the skin and sclera of the eye if it accumulates in the blood, a condition known as jaundice. Instead, the plasma protein albumin binds to bilirubin and carries it to the liver, where it is secreted in bile and also contributes to the color of feces.
An iron-containing protein is called a heme protein, which includes hemoglobin and myoglobin. These proteins are crucial for transporting and storing oxygen in the body.
protein, iron and nutrients for a healthy balanced diet
Hemoglobin is the iron containing protein in our red blood cells that combines with and carries oxygen.
Proteins are composed principally of amino acids. Some proteins also contain metals like iron and copper.
Heme is decomposed into iron and biliverdin
Hemoglobin molecules liberated from red blood cells are broken down into subunits of heme, an iron containing portion, and globin, a protein. The heme further decomposes into iron and a greenish pigment called biliverdin. Biliverdin eventually is converted to an orange pigment called bilirubin.
Iron(III) sulfide (Fe2S3) breaks down into iron(III) oxide (Fe2O3) and sulfur dioxide (SO2).
The spleen breaks down old red blood cells. The contained hemoglobin is released, which is further broken to globin, a protein and heme, a porphyrin.The heme is converted to bilirubin, which moves from the spleen to the liver attached to albumin. (Both feces and urine get their color from the products of the breakdown of the heme.) The iron recycled from the breakdown of the heme group is stored in the liver.

Spleen
it goes up into space and breaks down to a gas
Most of the iron in the body is hoarded and recycled by the reticuloendothelial system, which breaks down aged red blood cells. So i think its the spleen as spleen is a part of recticuloendothelial system.
