Now this would be some seriously good news if the tallow is high quality tallow coming from pasture-raised and grass-fed/finished cattle.
Most toxins resulting from industrialized cattle industry are stored in the inert adipose (fat) tissue. Rendering tallow from low quality animals does not make it healthier.

Q: Can rendering the fat of low quality cattle produce high quality, healthy tallow?
———
Rendering low-quality fat from cattle will not produce high-quality, healthy tallow. The diet, health, and living conditions of the animal are the primary factors that determine the quality of the fat. The rendering process can purify the fat by removing solids and moisture but cannot improve its fundamental nutritional profile or remove accumulated toxins.
How an animal's quality affects its fat
The characteristics of the animal's life directly impact the composition and health profile of its fat.
Diet: The single most influential factor.
Low-quality cattle: Typically fed grain, corn, and other by-products in a feedlot, leading to a softer, whiter fat.
High-quality cattle: Grass-fed and finished cattle have fat that is higher in beneficial nutrients, such as:
Omega-3 fatty acids
Conjugated linoleic acid (CLA), which has anti-inflammatory properties
Antioxidants like vitamin E and beta-carotene
Toxin accumulation: Low-quality cattle may be more susceptible to stress and illness. Studies show that environmental pollutants and toxins are often stored in the fatty tissues of animals. Rendering does not eliminate these toxins, meaning that tallow made from unhealthy cattle can contain these contaminants.
Health and living conditions: In addition to diet, an animal's overall health and living conditions impact its fat. Poor conditions can lead to stress or illness, which affects the quality of the fat and the final rendered product.
What rendering does and does not do.
The rendering process is a purification and preservation method, not a means of quality transformation.
Purifies: By slowly melting the fat, rendering separates the pure fat from water, meat solids, and other impurities. The final product is a shelf-stable fat with a high smoke point.
Preserves: When done correctly, rendering preserves the nutritional and fatty acid profiles that were present in the original raw fat.
Does not improve: Rendering cannot add nutrients to the fat. It cannot remove toxins that have been stored in the adipose tissue over the animal's lifetime. The process simply yields the purest form of the fat that was there to begin with.
Ultimately, the quality of the finished tallow is directly tied to the quality of the source fat. High-quality, healthy tallow can only be produced from the fat of high-quality, healthy cattle.
