Pioneering the Export of Hay from Energy Plantation Leaf Waste

The high demand for feed, especially protein elements in Europe, on the other hand, is an opportunity in itself. Leaf waste from energy plantations in abundant quantities can be used as an export commodity to fill this opportunity. These leaves can be processed into hay and then compacted (biomass densification) into large boxes (cubes) and ready for export. Under tropical climate conditions, biomass production, especially for renewable energy, feed and food through energy plantations, is an ideal solution. Wood product will be used as bioenergy, especially into wood pellet product, leaf as an export commodity for animal feed, and honey as a highly nutritious multi-functional food. Millions of hectares of potential land for the creation of energy plantations so as to maximize the benefits of land use, especially with the tropical climate conditions that support.

Learn from the state of Oregon in the United States which is successful as an exporter of hay grass as a source of fiber in animal feed. It is recorded that more than 900,000 tons per year export hay grass from Oregon to the destination countries, namely Japan, Taiwan and Korea. The business has been around for more than 30 years. The mechanization of agriculture and the use of modern agricultural techniques have helped the business grow. A number of grass species that they cultivate include annual ryegrass (Lolium multiflorum), perennial ryegrass (L.perenne), bent grass (Agrostis spp.), fine fescue (Festuca spp), Kentucky blue grass (Poa pratensis), Orchard grass (Dactylis glomerata) and tall fescue (F.arundinacea).

The difference between hay and dry straw (straw) is sometimes still confusing. Hay is made from fresh stalks, leaves and shoots of plants. Many plants can be used as hay, for example in Iowa, USA alfalfa and clover are most commonly used. If it is cut and packaged (compacted) almost all of the nutritional content is not lost and is used as animal feed. Meanwhile, straw is also made from the stalks and leaves of plants, but is cut after the plants are mature with their shoots or the fruit has been harvested for something else. This straw has very little nutritional value and is used primarily as animal bedding. The conditions for plants to make hay are fine textured, harvested at the start of the flowering season and harvested from fertile areas.

Hay production is carried out by cutting the forage (grass or leaves) then withering and drying the forage, then to facilitate storage, transportation and use, the hay needs to be compacted. Animal feed in dry form such as hay will make it able to hold out until the nutrients are maintained. The history of hay production is thought to date back to the late 19th century, when alfalfa was introduced to Iowa and became the most popular crop for hay production. Alfalfa itself comes from Central Asia which was first used for animal feed and then this alfalfa spread to various parts of the world. Legume leaves from energy plantations are also very potential as animal feed and processing them into hay will increase their utilization including their economic value. In the commercial hay industry modern mechanical devices are used primarily for compaction by making blocks or boxes with a high production target, as shown in the video in the following link here.   

Production of Synthetic Boards*, Ruminant Livestock and Animal Feed Industry from Biomass Plantation

Synthetic boards such as laminate, particleboard, fiberboard and cement board can be made from wood produced by biomass plantation. In addition to the small size of the wood, it is also of low quality which currently does not have an adequate utilization value. Forests or biomass plantations can be used as the raw material for the synthetic board. With fast rotation crops with short rotation coppice and fast growing species, such as calliandra and gliricidia, it is very potential as raw material for the synthetic boards. The production of this synthetic boards also uses the same type of raw material as wood pellets, namely wood waste or wood worth as wood waste. Wood produced from this biomass plantation is included in the second group, namely wood worth as wood waste. Even on the other hand, the large wood processing industry that produces a lot of wood waste, not a few who process the waste for the production for wood pellets and synthetic boards.

However, it would be better if the source of raw material for the synthetic boards production comes from forests or biomass plantations so that not only wood is the raw material for the artificial boards but also leaves and flowers. The leaves can then be used as ruminant animal feed and even the production of animal feed as a separate industry. While the flowers from the plantation can be used for honey bee farming. In livestock business, especially ruminants, feed is the highest cost component which is estimated to reach more than 80%. The forest or biomass plantations cover an area of thousands of hectares and are capable of being the main feed source for large ruminant livestock. Even if there is a large surplus, the animal feed industry also needs to be made independent.

Animal feed in the form of hay and pellets is suitable for long distance use because transportation costs will be cheap. Basically all parts of the tree can be utilized so as to provide optimal benefits. To maintain the sustainability of the forest or biomass plantation, good management is also needed so that the productivity performance of the forest or biomass plantation can be maintained. Along with the increasing population, the need for housing and other means of living also increases as well as food. Forests or biomass plantations can help overcome both problems.

*Synthetic boards are laminated board, particle board, fiberboard and cement board. While plywood is not included in it, although plywood is also a type of synthetic board. Plywood production from veneer sheets derived from large diameter wood, is not like this biomass plantation.

Hay Production Urgency

In countries with four seasons, in winter, plants grow very slowly and even stop growing, so hay is used as a feed supplement, while in Indonesia in the dry season, grass is also limited forage, so to maintain livestock performance, additional feed such as hay should be used. By making hay, animal feed becomes durable so that it can be used as a source of feed when supply is reduced. Dry and compacted conditions make hay easy to store and use. In breeding-oriented farms, the quality of feed is usually not as good as in fattening-oriented farms. Breeding duration is longer than fattening is one of these considerations, because feed is the highest cost component in livestock business.

Due to various factors such as geography and labor conditions, a number of countries even have to import animal feed, especially the hay. The United States, for example, exports no less than 700,000 tons of hay annually to Japan, Taiwan and Korea. Leaves of leguminoceae such as indigofera, calliandra and gliricidia are potential sources of ruminant feed for the production of hay. Besides being planted specifically for the production of hay, these legumes can also be used as energy plantation or biomass plantation. The integration of energy plantation or biomass plantation with livestock businesses, especially the production of animal feed in the form of hay product, is a very interesting combination.

In addition to the export market, the domestic or local market is no less interesting. Areas with large areas of land can be used as centers for hay production, which is then distributed to a number of ruminant livestock centers. Hay is dry and compacted (densified) so that it is easy to distribute even over long distances. This is different from silage, which is wet, so it cannot be compacted like the hay. With the fulfillment of feed, the performance of ruminant livestock business can be maintained. In energy plantation or biomass plantation, wood can be processed into energy products such as wood chips, wood pellets, wood briquettes and sawdust charcoal briquettes, or non-energy products such as particle board. That means all parts of the tree can be utilized. 

Planning Long-Term Feed Supply

Feed is the highest cost component in animal husbandry with a share of about 70%. Thus, feed has an important role for the sustainability of the business. Planning in the provision of good feed will reduce the risk of failure, including a decrease in the production of these farms. Maintaining the high performance of the livestock industry is not an easy thing, of course, including maintaining the quality and quantity of the feed. Feed planning for long-term supply needs to be done carefully and comprehensively so that livestock business can be optimal. Seasonal factor is an important factor in the availability of the feed. The success rate and the amount of profit earned can also be predicted better.

In commercial business, ruminant feed, especially sheep, goats and cattle, is generally easier to obtain than poultry or chicken feed. Imports of soybean meal have been carried out for the poultry or chicken feed. Chicken meat is still ranked 1st as a source of animal protein in Indonesia with a portion of around 70%. Whereas for the ruminants above, generally the feed can be provided by local food sources such as grasses and legume plants. But along with the narrowing of the land that can be used for forage crops, the more limited the availability of feed for livestock, especially for pasture. This condition makes it difficult for ruminant farms to be developed in large capacities or industry-oriented. Energy plantations with an area of up to thousands of hectares are expected to be a solution for this.

The development of energy plantations itself is closely related to the use of renewable energy, especially biomass, both locally / domestically and globally. In line with the bioeconomy era, the use of fossil fuels as well as for the manufacture of various other products is reduced, so biomass will receive more attention and will be increasingly used. This should be in line with the growth of the ruminant livestock sector and the halal industry in general. Related to animal feed, there are 3 important things that need to be considered, namely nutrition, safety and sustainability. Apart from these factors, technological, logistics and good management factors also play an important role in the long-term sustainability of the feed supply. If all the elements of feed (fiber, protein, vitamins, minerals, etc.) can be fulfilled from local / domestic sources so that the price is cheaper, the livestock business will be more competitive. Meanwhile, if it depends on imports, the cost of feed will be expensive and the livestock business will be less competitive so that the output of meat and milk products as a source of protein will also be expensive. And don't let the domestic animal feed production grow, say 5 times but imports of raw materials 15 times.

Production of Box Shaped Hay From Gliricidia Leaves

Apart from market, feed is another important factor in livestock business. Striving for and ensuring the availability of feed throughout the year both in quality and quantity is a challenge in itself, especially industrial-oriented ruminant farms. The productivity of livestock products is largely determined by these feed factors. The important role for livestock is for the growth of young livestock and for maintaining life and producing products (milk, calves/lamb, meat) and power for adult livestock. Another function of feed is to maintain endurance and health. In order for livestock to grow as expected, the type of feed given to livestock must be of good quality and in sufficient quantities.

In addition, livestock productivity itself is influenced a lot by environmental factors, namely up to 70%, while about 30% is genetic factors. And among these environmental factors, the aspect of feed has the greatest influence, which is around 60%, for example superior sheep farming such as the dorper type but if the quality and quantity of feed is not met then the results are also not optimal. Meanwhile, in terms of livestock business, the cost of feed is also the largest production cost, namely 60-80% of the total production cost. So it is very natural that attention or focus on feed issues is very important.

Seeing the above conditions, processing technology for animal feed is important. The purposes of animal feed processing include preserving nutrition and extending shelf life. Drying the leaves of gliricidia or calliandra to a moisture content of about 15% is one such effort or commonly called hay. By making hay the two objectives of processing animal feed above, namely maintaining nutrition and extending the shelf life can be achieved, but with a large volume of dry feed or hay (bulky) it will be inefficient in using space for storage or if it is to be used in other places where need quite far transportation. This is why it is necessary to apply biomass densification technology to solve this problem. Hay compaction into blocks or box shaped is a practical and easy undertaking. The equipment and compaction process into box shaped is also easy and cheap, compared to other biomass compaction technologies such as pellets or briquettes.

A sheep or cow farm should be built near the energy plantation so that they can easily get a source of feed for the gliricidia leaves. The leaves are then made hay and compacted into the blocks / box shaped. And because gliricidia leaves are a source of protein, so to be a complete feed, another source of feed is needed. This can be fulfilled by the surrounding community with community empowerment patterns or for more details, please read here. Sources of feed from the community, for example a source of fiber from grasses or agricultural waste, can also be made hay, so that the farm is available as a complete feed (complete feed) which is safe for the operation of the farm business. And because the estimated leaf production from energy plantations is very abundant, some of the hay that is produced can also be sold elsewhere. 

Technology is basically a tool to achieve a goal. From a technological point of view, namely biomass densification, besides the raw material for glicidia leaves can be made hay, the leaves can also be made into pellets or briquettes. The main difference between pellets and briquettes is only a matter of size, briquettes are bigger than pellets. The form of puck briquettes like the photo above is the best form for animal feed applications. From a technical perspective, pellets and briquettes are also denser or have a higher density than hay. The dust problem in hay can also be reduced by making these pellets or briquettes. But it is true that making pellets or briquettes requires higher investment costs and the production process is more complex.
