Leucaena trees were intensively used in the past to produce charcoal. However, Leucaena plantations still provide fuel wood, easing the pressure from native forests in many countries where the species were introduced, such as the Philippines. When converted into charcoal, Leucaena wood doubles its heating value, despite initially losing its overall mass. It produces high-quality charcoal that burns with reduced smoke and ash production.
Leucaena wood is used to produce paper pulp. It has higher cellulose content than other hardwoods also used in the paper industry, and is often blended with long-fiber pulp in the paper industry. The fibers extracted from Leucaena wood is also used in the production of some fabrics, such as rayon.
Leucaena wood quickly absorbs waterborne preservatives, such as copper-chromearsenate and creosote. Treated Leucaena wood posts are resistant to fungal and insect infestations. They are used in fences, telephone or power transmission poles, scaffolding and pole houses, which are traditional in Asia. Poles are also used to support pepper, banana, beans and other climbing crops.
Leucaena produces a medium hard lumber used in the furniture and building industry, but also in the production of parquet and other types of flooring. Suitable over concrete and other solid floors, parquet are wood tiles that are glued to the floor, often in different pattern arrangements, such as zigzag and square panels.
