A Bolivian farmer has developed a small plant to convert plastic waste, old tires, and used oil into fuel for his tractors, offering a cost-effective alternative as state diesel subsidies are removed and market prices soar.
This initiative highlights a potential solution for farmers facing high fuel costs due to subsidy cuts and rising global energy prices, demonstrating resourcefulness in adapting to economic pressures and reducing reliance on imported fuels.
In the Bolivian Altiplano, a farmer named Etson Machaca has developed a small-scale plant that converts waste materials like plastic bags, old tires, and used oil into fuel for his tractors. This innovation comes as Bolivia's government recently ended state diesel subsidies, leading to a surge in fuel costs for farmers who rely heavily on diesel-powered machinery for their livelihoods.
The plant, located in the community of Ancocala, uses a pyrolysis process to break down materials at high temperatures in the absence of oxygen. It produces between 80 and 150 liters of fuel daily at a cost of 7 to 10 bolivianos per liter. This is a significant saving compared to the open market price of approximately 18 bolivianos per liter for diesel. Machaca uses the fuel exclusively for his tractors and farm equipment, emphasizing its importance for planting crops in the region.
Bolivia faces substantial energy import challenges, with official data indicating the nation imports 95% of its diesel and 60% of its gasoline. The country's reliance on foreign fuel purchases has grown as its domestic liquid hydrocarbon output has declined.
