Environmental remarks In Brasil, Thailand and Cambodja, Teak is extracted from the tropical rain forest. Deforestation of tropical wood causes serious local environmental problems and is possibly related to the climate change in the world. In Africa Teak is cultivated in, what is supposed to be, a sustainable manner. The average transport to the Netherlands requires 2 * 250km (from factory to forest and back) by trailers and 9397km to the Netherlands. Chemical structure: 41.7% cellulose, 16% pentosane, 34% lignin, 1.2% acethyl, 12.6% extractives, 1.8% ash
