Which term refers to the process of turning human remains into soil?

The process of turning human remains into soil is referred to as Natural Organic Reduction (NOR). This method is an environmentally-friendly alternative to traditional burial and cremation. It involves using a process of controlled decomposition that transforms bodies into nutrient-rich soil. NOR is designed to accelerate natural decomposition while ensuring that the process is safe and respectful.

In this method, human remains are mixed with organic materials, such as wood chips and alfalfa, in a controlled environment where microbes and bacteria can work to break down the materials over a period of weeks to months. The outcome is a compost-like substance that can be used to enrich soil, thus contributing positively to the environment.

The other processes mentioned do not achieve this specific transformation. For example, cremation involves the incineration of bodies, turning them into ash rather than soil. Burial retains the body in the ground while allowing for natural decay but does not convert remains into soil in a purposeful, expedited manner like NOR. Biosolids processing deals with the treatment of sewage sludge, which is not related to human remains. Therefore, Natural Organic Reduction stands out as the correct answer for achieving the transformation of human remains into soil.
