Producing and using macadamia
Aborigines crack nuts macadamia with stones. John Waldron, one of the first people who established macadamia orchards, passed the hammer and anvil. In fact, during a period of more than 50 years, he broke about eight million nuts with acetic simple tools as the first invented machines have not been very effective, for crushing and stone. Over time, however, were built performance cars. Another problem encountered was related to the propagation of macadamia trees. Once planted, a variety of good nuts will often produce poor quality trees. Either by grafting has not obtained results. Because of these obstacles, growing trees for commercial purposes has stalled, at least until the intervention of Hawaiian, bringing amazing innovations in cultivation techniques. As a result, they soon managed to have 90% of world production of macadamia nuts. Eventually, acetic nuts came to be called Hawaiian. In the 60s of last century, Australian growers have begun to look seriously for commercial cultivation of macadamia trees, applying techniques learned in Hawaii. Local industry has flourished so much that Australia currently has about 50% of the world’s macadamia nuts. Trees are grown in Africa, Central America and Asia. Macadamia nut shells, the hardness of stone, have a calorific value almost equal to that of lignite. Therefore, an Australian energy company uses the power generation plant not only for itself but for the local power grid. This is the first project to transform Australian waste ENREG. It is expected that plant productivity will increase as more and more growers will provide “fuel” necessary.
