The main challenge is cold-flow performance; pork fat biodiesel may gel at low temperatures. This is mitigated by using winterization, additives, or blending with diesel (B20 or B50). Otherwise, pork biodiesel is compatible with most diesel engines, offering high lubricity, clean combustion, and reduced wear. The GlobeCore USB plant ensures biodiesel is purified, moisture-free, and compliant with standards, reducing risks like injector clogging or fuel filter blockages.
