Brazil: Energy from Eucalyptus

According to Austrian-based machine provider Lindner-Recyclingtech GmbH, the generation of refuse derived fuel (RDF) from eucalyptus bark in Brazil is a market with great potential.

Udo Siebert, sales and service partner of Lindner Recyclingtech in Brazil, is convinced that Lindner’s all-rounder Urraco 75 is the best machine to shred eucalyptus bark, which pulp and paper mills as well as wood panel producers in Brazil use to generate RDF to supply their own energy. When the Brazilian government banned the landfilling of eucalyptus bark two years ago, the demand for machines from the Urraco series rose. As reported, two global leaders in pulp production and one renowned wood panel producer already use the tried-and-tested Lindner universal shredder in their plants: Eldorado Brasil in Tres Lagoas, Fibria in Aracruz and Fibraplac in Glorinha.

The bark with low calorific value is shredded and then mixed with wood chips and other inert material, turning it into fuel with high calorific value that can then be used directly to generate energy in the producers’ plant kilns. All three Brazilian companies selected the mobile shredder Urraco 75 by Lindner with a 350 PS-strong AdBlue SCR diesel engine complying with Latin America’s emission standards, Lindner-Recyclingtech gave account. “The two-shaft shredder’s design-inherent classic crushing process involving low shaft speeds minimizes dust formation at the same time,” the provider emphasized. “The intelligent system with two tilting hoppers which can be inclined by as much as 80 degrees promotes an optimum supply of feed material to the shafts. Depending on the shaft employed, the Urraco powerfully shreds – without damaging the material – wood, biomass, root wood, paper rolls, domestic and commercial waste, mixed construction waste, concrete sleepers, bulky waste, electronic and lightweight scrap, aluminum profiles, car bodies, and much more.”

According to the information, the clients in Brazil who produce RDF from eucalyptus bark are pleased with the shredder’s low wear and tear and low fuel consumption of 0.8 to 0.9 liters of diesel per ton of bark. Up to 300 tons of bark are processed daily in the producers’ plants. The Urraco 75 operates on average six hours a day and shreds the material to a grain size of 120 millimeters. The hourly output is 30 tons.
