Animal fat, usually a by-products of meat processing, can be used as a feedstock for biodiesel, biogas and other types of bioenergy. Normally considered a distant secondary feed stock in the West, animal fat in many developing countries may be one of the cheapest and most accessible feedstocks for SVO and biodiesel production.

Animal Fat Use in Developing Countries

In many developing countries where waste vegetable oils or straight vegetable oils are either not available or too expensive, animal fat may represent ways forward in developing the SVO and biodiesel production sectors. Because the cost of the feedstock represents 60-90% of the final cost of production of biodiesel, it is critical to find the lowest cost feedstock possible for this newly emerging industry.
Benefits of animal fat for biodiesel in developing countries include:
- Increasing the variety of feedstocks (with animal fat) making the potential for a more robust fair feedstock market
- Rendering fat is already widely done for candle and soap making industries.
Benefits of animal fat for SVO systems in developing countries include:
- It’s low tech.
- The parts needed for making filtering are widely available.
- Putting “grease” systems into old diesel vehicles (bypassing warranty issues) / tractors/ small single cylinder engines pumpsets-generators is a good example of an appropriate technology.
- It can be blended at any proportion with fossil diesel.
- It makes clean fuel much more accessible to the less well off because it eliminates the need for all of the cost, complexity (procurement of methanol and lye, training in chemistry, etc.), danger (toxic chemical handling) involved in making biodiesel.
- You get dramatic air quality benefits, even at low blending levels in terms of particulate matter, sulfur, CO, and other harmful emissions (with the exception of NOx which may decrease or increase slightly depending on the feedstock used, the engine, etc.).
