Small Scale Wet Rendering Process

Basics

• This page aims to outline a process for Rendering of Animal Product Residuals at a Small Scale (Homestead/Prosumer-Small Community Farm etc)
• Main residuals would be Bones/Cartilege/“Gristle” etc
• While obviously not as great in terms of Hierarchy of Controls substitution (ie Veganism etc), to an extent it could aid in Waste Reduction / Waste Cleanliness
  • ie not having rotting stuff in your MSW
• Unlike a giant Rendering Plant etc too, the ESG aspects would be better in terms of not having someone run the ‘’’bone grinding machine’’’ or someone cleaning out the nasty oil tanks etc
  • RE: User: Eric ‘s experiences at LES etc
  • Granted if using State of the Art Odor Emissions Control practices+equipment, and high quality equipment with well paid, well trained, well treated staff etc (and of course Temple Grandin or better Animal Welfare + Some magically low carbon permaculture intensive grazing unicorn type crap it could POTENTIALLY be done fine at scale

Equipment

• Pressure Cooker
• Some means of Oil-Water Separation, in the cooking sphere a “Gravy Fat Separator” may suffice
• Means of straining out residual debris such as Bones/Bone Mean
  • Sieves, Cheesecloth, etc
• If intended for non-immediate Consumption, some means of packaging such as Canning gear
• Potentially blending/size reduction equipment if so desired
• Potable Water + Wastewater treatment
• POTENTIALLY a solid waste stream such as Compost
