Methods of decontaminating bone tissue and an apparatus or system for the same are provided. The methods can be multi-batch processes and include contacting the bone tissue having contaminants with carbon dioxide to decontaminate the bone tissue and to form carbon dioxide having contaminants. The contaminated carbon dioxide is collected and the contaminants are removed to obtain purified carbon dioxide which can be recycled to treat contaminated bone tissue. The contaminated carbon dioxide can be purified by bubbling it through water and/or an organic solvent followed by acid treatment, filtering and liquefying the carbon dioxide. Contaminants that can be removed from contaminated bone tissue, and in turn, from contaminated carbon dioxide include infectious organisms, bacteria, viruses, protozoa, parasites, fungi and mold or a mixture thereof

A system for treating contaminated bone tissue with purified carbon dioxide, the system comprising a bone tissue chamber configured for holding contaminated bone tissue and receiving purified carbon dioxide into the bone tissue chamber and evacuating contaminated carbon dioxide from the bone tissue chamber;
A system for treating contaminated bone tissue with purified carbon dioxide, the system comprising a bone tissue chamber configured for collecting a contaminated carbon dioxide from a carbon dioxide treated contaminated bone tissue and removing the contaminated carbon dioxide, and a purification chamber configured for purifying the contaminated carbon dioxide with a supercritical fluid to form a purified carbon dioxide, liquefying the purified carbon dioxide to form a liquid purified carbon dioxide and using the liquid purified carbon dioxide as a cooling fluid and separating contaminants from the collected contaminated carbon dioxide.
