Rendering is a process that converts waste animal tissue into stable, usable materials. Rendering can refer to any processing of animal products into more useful materials, or, more narrowly, to the rendering of whole animal fatty tissue into purified fats like lard or tallow. Rendering can be carried out on an industrial, farm, or kitchen scale.
Commercial tallow commonly contains fat derived from other animals, such as lard from pigs, or even from plant sources. Tallow consists mainly of triglycerides (fat), whose major constituents are derived from stearic and oleic acids. The solid material remaining after rendering is called cracklings, greaves, or graves. [1] It has been used ...
White tree paint is commonly applied to citrus trees to keep the affected tissues from overheating, as dark-colored paint can raise the surface temperature of the treated tissues. The classic tree paint is black, because it is based on an asphalt emulsion. Tree paint may be applied using spray cans, paint guns, or brushes.
Depending on the temperature of the fat, it can change between a solid state and a liquid state. Chemically, both fats and oils are composed of triglycerides . [ 2 ] [ 3 ] Although many animal parts and secretions may yield oil, in commercial practice, oil is extracted primarily from rendered tissue fats from livestock animals like pigs ...

Tallow after rendering. The primary use of suet is to make tallow, although it is also used as an ingredient in cooking, especially in traditional baked puddings, such as British Christmas pudding. Suet is made into tallow in a process called rendering, which involves melting fats and extended simmering, followed by straining, then cooling. The ...
A single tallow tree can produce nearly 100,000 viable seeds annually that can remain in the soil for several years before sprouting. A mature stand can produce 4,500 kilograms of seeds per hectare per year. [17] These seeds are easily carried to different places by birds and water. Tallow trees can remain productive for 100 years.
