Economically, mutton fat biodiesel benefits from low feedstock cost (when regionally available), renewable energy incentives, and byproduct utilization. Challenges include variable fat quality, transport logistics, and cold-weather limitations. Environmentally, converting mutton fat reduces waste, methane emissions, and reliance on food crops. The GlobeCore USB plant supports modular scalability, allowing producers to start small and expand with demand. Regulatory compliance, sustainable sourcing, and energy efficiency are key for long-term viability in large-scale applications.
