Solid Residues

Created: 17 April 2015

Companies in the planted trees industry adopted the practice of strict management of solid waste resulting from its activities, not only forestry waste, but also industrial waste, aiming at reducing waste generation and guaranteeing the best disposal possible for waste, complying with legal requirements and related certification.

In forestry activity, 99.7% of solid waste, namely bark, branches and leaves are kept in the field as protection and soil fertilizer.

In the industry, 65.8% of waste is destined for power generation. Waste is burned in boilers that generate steam and, eventually electric energy for the production process, eliminating the use of fossil fuel. In addition, 25.2% of waste—mainly from sawed wood production (chips and sawdust) and wastepaper—is reused as raw material by companies in the planted trees industry. Other waste such as lime mud and boiler ashes represent 5.5% and is reused by other industrial sectors to produce cement and recycled fuel oil, for instance.
