Brazil eyes 20% biodiesel blend: Tests begin in May

Brazilian researchers are preparing to test higher biodiesel blends in diesel fuel, with investigations into a 20% blend, known as B20, slated to begin in May. The Maua Institute of Technology will conduct initial tests on B15 and B20, with engines running for 300 hours to assess performance and potential issues like filter clogging. These tests are a critical step in Brazil's strategy to bolster its biofuel sector and decrease reliance on imported energy sources. The country, already a significant producer of biofuels from soy and sugarcane, currently mandates lower blends.

Further phases of testing will also analyze pollutant emissions for blends of 7% (B7) and 25% (B25) biodiesel. Industry representatives have welcomed the planned evaluations, viewing them as a promising development that could pave the way for wider adoption of advanced biodiesel blends. The research is expected to yield valuable data supporting the increased use of biofuels, aligning with Brazil's broader energy security objectives and its position as a global leader in biofuel production.
