Energy Plantations: Not Only Wood Pellet Production But Must Also Support the Livestock Industry

The concept of energy plantation or biomass plantation by utilizing the whole tree seems to be still unpopular at this time. But sooner or later, God willing, it will happen because profit-oriented wood pellet companies will certainly maximize this aspect or profit, of course as long as it does not damage the environment and CSR (Corporate Social Responsibility) will be pursued in other ways. The main orientation currently focusing on wood products for wood pellet raw materials is certainly a good thing, but it would be much better if the benefits of all parts of the tree could be maximized. If this can be done, the benefits will not only be in the energy sector but also in food and feed, important sectors that are essential in human life.

The main composition of energy plantation leaves such as calliandra and gliricidia is protein and this protein element is an important and most expensive component compared to other elements of animal feed. With a large volume of leaves from energy plantations, it should support the livestock industry and not just be thrown away because it is just a by-product or waste that is less useful. In fact, from the livestock industry side, the opposite is true. The utilization of these leaves can be used directly on livestock or processed into animal feed in a processing industry depending on the local situation and conditions.

Large farms can be made from the utilization of energy plantation leaves as well as animal feed factories from the leaves. Leaf pellet production can be done with a production process similar to wood pellet production so that a wood pellet factory adjacent to a leaf pellet factory is also very possible. Like export-oriented wood pellet products, leaf pellets can also be the same. Meanwhile, if a large farm is to be carried out, waste from the livestock farm or animal waste can be used as raw materials / substrates for biogas production. The biogas can then be used for drying in the production of wood pellets or leaf pellets or used for electricity production. The residue from the biogas will become organic fertilizer, either solid organic fertilizer or liquid organic fertilizer. A simple diagram as below.

 

Thousands of cattle or breeding cattle are imported into Indonesia from Australia and New Zealand and cattle fattening is a promising business in Indonesia because the need for beef has not been met until now. The shortage of beef is met by importing buffalo meat from India and beef from Brazil. Support for the availability of abundant and quality feed is one of the important aspects of self-sufficiency in this meat. In addition to cattle, the need for goats and sheep is also very large. Yogyakarta, a city that is also famous for its goat satay cuisine, needs more than 1500 heads of sheep per day. In addition, the need for aqiqah and Eid al-Adha is also very large. The sheep export market is also very promising, which until now has not been met due to various factors, one of which is the feed factor. Feed in the livestock business plays a very important role or even around 70% of the cost of livestock is the cost of the feed. And livestock is a link in the chain of food needs for humans so that it is inseparable.  

Wood Pellet Production With Integration of Degraded Land Use For Energy Plantations, Cattle and Biogas Resources

There is a huge demand of wood pellet and on the other hand also the extent of uncultivated land in a number of places in Indonesia potentially be used for energy plantations with an output is wood for raw material of wood pellets. Currently estimated at more than 6 million hectares of unused land in Indonesia. While forage on plants short rotation species such as gliricidae and calliandra be useful as animal feed  of the cows. For every hectare is expected to be a source of cattle feed by approximately 6 tails. If there are 5000 ha of degraded/unused land it will produce around 100,000 tonnes of wet wood as a source of raw material of wood pellets and maintain 30,000 head of cattle. A large number of these cows potential as a source of biogas to meet the energy needs of the business itself.

The roots of the plants short rotation species is able to bind nitrogen that enrich the soil fertility. The root is able to perform a symbiotic relationship with bacteria in the soil, ie Rhizobium spp. Trees provide carbohydrates and energy for rhizobia bacteria, and rhizobia change of atmospheric nitrogen into nitrogen in the soil which can be exploited by tree roots. This process is known as nitrogen fixation, which took place on that form nodules on the roots of trees. Nodule should much, and when it opened in the red or red-pink. If the nodule is green, brown or black, is not binding nodule nitrogen. And plus organic fertilizer from biogas residue so that the land will be fertile and plantations productivity more can be expected to continue its sustainibility. 

Good management supported by a team of professionals will support the future success of your business. Production of wood pellets can be used as first priority , then followed by dairy farms and biogas and organic fertilizer as a supporter. The concept of zero waste, green industry and sustainable implemented in the integration of this business.
