Enhancing Life Cycle Modelling of Waste-Based Biodiesel: Integration of Beef Tallow Rendering Emissions into Brazil’s National Biofuel Policy (RenovaBio)

Short Introductive summary

Global projections indicate robust growth in biodiesel production, reaching 80.9 billion liters by 2034, driven by the search for low carbon fuel alternatives. In this context, the use of animal fats (e.g., beef tallow) emerges as a strategic feedstock, as it does not compete with food production, offers advantages such as lower carbon intensity, and mitigates the risk of environmentally incorrect disposal of a slaughter chain by-product. To ensure data reliability, the complete environmental burden associated with the rendering process was incorporated into the calculator of Brazil’s National Biofuel Policy (RenovaBio). This approach enables a more robust and transparent calculation of emissions, aligned with RenovaBio’s methodological framework, since its first version did not account for this step. Based on this update, the study aims to quantify the impacts from the biodiesel produced from beef tallow in Brazil, comparing the results with other methodological assumptions and data from the literature.
