As the pathogens would be spread by the flies, scavenging animals or ground water - or other vectors, this is the true danger of mass graves. Quicklime and slaked lime both act as biocides, preventing/reducing the growth of maggots and pathogenic microorganisms. The bodies will still decompose, but in a slower, less dangerous fashion.
It will also neutralize and immobilize acidic components formed in the decomposition process. This will reduce the odour of decomposition. For this purpose lime is also used in the treatment of sewage and of animal & human feces. For example in outdoor toilets, powdered lime or limestone should be added regularly, to suppress the stench.
Calcium oxide is usually made by the thermal decomposition of materials, such as limestone or seashells, that contain calcium carbonate (CaCO 3; mineral calcite) in a lime kiln. This is accomplished by heating the material to above 825 °C (1,517 °F), [ 6 ] [ 7 ] a process called calcination or lime-burning , to liberate a molecule of carbon ...
Parchment is the skin of an animal, usually sheep, calf or goat, which has been dehaired, processed with a lime solution and stretched under tension. The dried material is a thin membrane which is most commonly used as a writing surface, but can also be used to make other items like bookbindings and drumheads .
The human body is composed of approximately: 64% water, 20% protein, 10% fat, 1% carbohydrate, 5% minerals. [1] The decomposition of soft tissue is characterized by the breakdown of these macromolecules, and thus a large proportion of the decomposition products should reflect the amount of protein and fat content initially present in the body.

Common wild pig (boar) corpse decomposition timelapse. Decomposition is the process in which the organs and complex molecules of animal and human bodies break down into simple organic matter over time. In vertebrates, five stages of decomposition are typically recognized: fresh, bloat, active decay, advanced decay, and dry/skeletonized. [1]
Lime is an inorganic material composed primarily of calcium oxides and hydroxides. It is also the name for calcium oxide which is used as an industrial mineral and is made by heating calcium carbonate in a kiln. Calcium oxide can occur as a product of coal-seam fires and in altered limestone xenoliths in volcanic ejecta. [1]
The remains of decaying plants or animals, or their tissue parts, and feces gradually lose their form due to physical processes and the action of decomposers, including grazers, bacteria, and fungi. [1] Decomposition, the process by which organic matter is decomposed, occurs in several phases.
