Calliandra energy plantations as the name implies are indeed prioritized or for the main purpose of producing energy from biomass, either wood pellets or just wood chips. This is because wood is the main product of the energy plantation, while leaves and flower nectar are by-products or are considered waste from the wood pellet or wood chip business. However, if the use of leaves for animal feed and flower nectar for honey production has an economic value that approaches or even exceeds the wood pellet product, then it will be a different story. Calliandra leaves, like indigofera leaves and glicidia / gamal leaves, have a high protein content, while this protein element is the most expensive source of nutrition of all the elements in animal feed products, while calliandra honey is one of the best quality honeys compared to other honey products such as acacia honey, kapok honey, rubber honey and so on.
Synchronization between honey and wood production is very important in the energy plantation to maximize profit. In honey production, the first time the calliandra flowers and the next flower cycle are very important. Don't let it be that just because of ignorance of the flower cycle, many benefits that should have been obtained are lost. In addition, for sustainable and optimal honey production, not only calliandra nectar is needed, but also a number of certain plants as support, both for additional bee feed and for making beehives. When all that is available is calliandra nectar, honey production will be maximized but will not be sustainable because the bee colony will shrink and then disappear. This is the importance of plantation engineering with a number of species or types of certain plants if honey production is also an important product in the calliandra plantation-based business.
Calliandra leaves in abundance will automatically be obtained when the calliandra trees are cut down or harvested. The calliandra leaves need to be separated from the wood and twigs to be used for animal feed. Animal feed products from calliandra leaves can be in the form of fresh leaves or processed leaves in the form of pellets, or hay. This makes it possible to have a leaf pellet factory in addition to the wood pellet factory. With an estimated leaf volume of 1/4 of the wood but the price of leaf pellets is around 3 times the price of wood pellets. So the profit from utilizing leaves into pellets (leaf pellets) is very large, estimated at 1/2 to 3/4 of the wood pellet turnover. This is certainly a serious consideration and cannot be ignored.
A comprehensive understanding of calliandra plantations for energy, food and feed is indeed very important to maximize profits from calliandra plantation-based businesses. This will encourage the calliandra energy plantation to grow further. In addition, the legality aspect and land selection for the location of the calliandra plantation. This is because, especially for wood pellet products in general, it is for export orientation and especially for Japan and Europe, environmental or sustainability certification is very important and even required so that the legality aspect (which is clear and clean) and land selectivity according to its designation including the history of the land are also very important. So optimizing calliandra energy plantations for energy, food and feed is possible if the terms and conditions are met.
