Although soft tissue decomposes within six weeks, the decomposition of an unembalmed body without a casket can take up to twelve years to reach the skeletal stage. This timeline can vary based on factors such as soil composition, moisture content, and oxygen levels. If an unembalmed body is inside of a casket, decomposition can take longer due to the barrier of the casket’s materials.
Decomposition accelerates in optimal conditions, allowing the body to reach the skeletal stage in one to two years. If the soil is fertile, it may take up to 20 years for the skeleton to fully decompose. In contrast, skeletal remains may exist indefinitely without much decay if buried in neutral soil or sand. The rate of decomposition can also be significantly slower in colder climates and may even be influenced by the depth or shallowness of the burial plot.
Embalming and casket usage can impede decomposition in different ways. Embalming replaces bodily fluids with preservatives to delay decomposition, while caskets provide a physical barrier against decomposition agents. If a body is neither casketed nor embalmed, the body’s natural fluids are subject to decomposition and the decomposition process will increase with the body’s direct contact with the soil. The soil itself can also influence the decomposition rate. For example, acidic soil can increase the rate of decomposition.
Decomposition is a natural process, and likewise, will noticeably differ under the conditions of natural or green burial when compared to traditional burial practices. The decomposition rate of an unembalmed body without a casket can vary greatly, often depending on numerous environmental factors. Ultimately, understanding these differences can be helpful in identifying arrangements that have minimal environmental impact and further contribute to the conservation of natural resources.
