Image Captions: 1) Wood Crab; 2) Machine crushed (powder); 3) Bin (container); 4) Dryer; 5) Pellet machine; 6) Cooler; 7) Packing Machine. Factory size: 150x30m2; Power: 5689kW; Workers: 12 people.

The process consists of:

1.      Wood Chipper Process: Prepare logs to be used, then crab logs with a size not more than 2-5 cm.

2.      Hammer Mill: Hammer mills are used to pulverize wood chips into sawdust (wet) with a size below 3-6 mm.

3.      Drying Process (Dryer): In order to meet the conditions of the pelletization process, the drying process is needed to reduce the moisture content of the raw wood powder (wet), so that the moisture content is not more than 15%.

4.      Pellet Making Process (Pellet Machine): pressing dry wood powder (<15%) with a pellet mill through roller and die contact. A vertical pellet machine should be used at this stage.

5.      Sifting Process (Sieve Shakes): Sieve the low quality pellets (split, broken, collapsed) during the sieving process. Separate the unsuitable shapes via the vibrating sieve as well as get rid of them through the sieve, then the failure is reprocessed.

6.      Process Cooling (Cooler): Cooling the temperature of the pellets. When the pellets come out of the pellet mill, the temperature of the pellets is around 60 oC. After passing through the cooler, the pellet temperature is slightly higher (5-10 oC) than the ambient temperature.

7.      Packing process (Packing machine): packing pellets for 10-50 kg / container.

South Korea is conducting joint projects in East Java, Central Java, Sumatra, Kalimantan and Papua. Indonesia will be South Korea's target to become a supplier of WP in the future in Asia, especially for biopelet materials from furniture waste, palm fronds, EFB, sugarcane bagasse, straw, red calliandra, sawdust, etc.

North Sumatra (Medan): PT Toba Hijau Sinergi which operates at the end of 2016 utilizes EFB palm (TKKS, oil palm) to become oil palm pellets used as alternative BB according to Law No.32 of 2009. The advantages of oil palm pellets are low humidity, efficiency high thermal energy, easy handling & storage, suitable for lattice system boilers, and low smoke output. Unfortunately, the ash content is> 3%.

Processing 1 ton of FFB (Fresh Fruit Bunches) produces waste of 0.23 tonnes of EFB; 0.13 tons of mesocarpfibre (fibers); 0.06 tonnes of palm shell, and 0.65 tonnes of LCPKS (Palm Oil Mill Liquid Waste). TKKS has only been used as compost (mulch). The processes used include:

Empty Bunch Crusher, Thresser, Empty Bunch Press, Shredded Empty Brunch, Cutter, Dryer, Bricket Machine, and Bricket Bunker. Assumptions: EFB (in FFB) 23%, PKS processing capacity 30ton / h, EFB produced ~ 6.9 ton / hr. One unit of 7ton / h capacity shredder is required. In brief, the process of making wood pellets: OPEFB is crushed (crushing), shredded (thressing), pressed (pressing) to reduce the moisture content, and pick up the remaining oil; then via conveyor it is sent to the drying unit (drying), cutter (cutting, max. 2 inch) and so on to the Tankos pellet machine. PKS capacity 30 thousand kg / h or 600 thousand kg / day, TKKS 138 thousand kg / day, OPEFB Pellets (40% of EFB) 55,200 kg / day, heat tilapia Tankos pellets 17,660kJ / kg (4,640kCal / kg), potential heat of pellets 974,832 .000kJ / day. Five kg of tankos pellets is equivalent to 12 kg of LPG gas cylinders. The tankos pellet machine alone costs ~ 33,000 USD.

Riau Kep: IDEAS in collaboration with PT APP (Achmadi Pasca Perintis) conducted a survey to develop an energy plantation and WP mill in Lingga (There are around 604 large & small islands).

•        West Java: WP factory in Ciamis, capacity of 2,500 tons / month (60% for domestic, 40% for foreign)

•        DI (Dahlan Iskan) has visited the WP factory (2x350kg / h, raw material for KM) Ds Rawa, Kec. Cingambul, Kab. Majalengka; to a tempe factory in Dukuh Semar, Cirebon, which tried WP Kaliandra.

•        DEAS and PT MBT (Mandiri Bintang Tiga) collaborate to develop calliandra energy plantations and WP factories in Sumedang, Kuningan and Bandung

•        Central Java: the largest wood pellet factory PT South Pacific, a furniture producer in Jepara, Central Java, produces WP from waste from furniture production which is popular in South Korea (70,000 tons / year), because of its good quality (high calories, chemical content and low enough ash). Four WP mills are planned to be built in biomass plantation centers in various locations (Max about 4 hours from Bandar Internasional).

•        PT SPI (Solar park Indonesia, in Kalikajar, Wonosobo Central Java), which was once predicted as a pilot project for wood-based biomass investment opportunities (as well as a WP factory) between South Korean Indonesia (200,000Ha) has been locally owned. Now it is being sold (Rp. 19.5 billion) to other parties (some of the machines have even been stripped down, and sold in pieces).

•        Semarang: PT Mahya Bioenergy, capacity 2,000 tons / month (max 10,000 tons / month), albasia wood, 4200-4600 kcal / kg, diameter 8mm, water content 7-9%.

•        Purworejo: PT EMI (Energy Management Indonesia) (a state-owned company via its subsidiary PT EBI) made cooperation with the Purworejo district government to build a new WP factory originating from red calliandra wood with a capacity of 36,000 tons / year. The production is to fulfill the demand of domestic taxpayers (250 tons / day) and Japan and South Korea foreign countries, which increase by 250 tons / day (10,000 tons / month) via LOI. Factory area 10 Ha.

•        DI Yogyakarta: One of the suppliers of WP (50 tons / month) to South Korea (and Japan) is PT Greeno Inovasi Energi from Ds. Among, Bangunjiwo, Bantul, DIY. The main raw material is sawdust obtained from Central Java & DIY, which is mixed with other biomass wastes such as rice husks, bagasse (bagas), tobacco dust, and waste banknotes. Tapioca flour is added to it as an adhesive.

•        East Java (Paiton, Probolinggo): PT Pellet Biomass Indonesia, producer of premium WP (calories 4600kcal / kg; moisture 8%; ash content 1.2%; minimum order: 16 tonnes; Surabaya port; 1 month delivery time; L / C, T / T; able to supply: 2000 tons / month).

•        Madura: April 2015, CV Gerbang Lestari established a WP factory which is managed by Ponpes Darul Ittihad in Ds. Kombangan, Kec. Geger, Kab. Bangkalan, Madura with a capacity of 1 ton / h with red calliandra wood as raw material of about 12 tonnes / day (1 day = 8 hours, wet raw material contains about 40% water). If a year = 310 days, then 12ton x 310 = 3720 ton / year of raw material is needed, or 3720/20 = 186 Ha of land is needed. Therefore, the harvested garden per day is only 186 Ha / 310 = 0.6 Ha. KM wood pellets selling price Rp. 1.6-2.5 million / ton. Meanwhile, the selling price of KM wood is only Rp. 367,000 / ton. After production is managed by ISE (IDEAS Semesta Energy, the machines are rejuvenated by CV SBE, Suryabaja Engineering), WP 2 tons / hour or 25 tons / day (a mixture of KM and Kemlandingan) was sent to Gresik, and PTPN 8 in Pangalengan,

•        Bandung (for BB drying tea leaves). Local users are starting to use WP as a substitute for LPG gas which can save 47% costs, which is equipped with the use of a WP stove in one package with the WP. The idea will also be developed in Mamuju (Sulbar) and North Lombok (NTB). Kaliandra red wood is harvested after 14 months by CV Gerbang Lestari. The optimum production is 20 tons / Ha / year. The local people took advantage of the calliandra energy plantation project in a 214 hectare village forest and a 200 m2 WP mill (assistance from ICCTF, Indonesia Climate Change Trust Fund). Meanwhile, the WP product is used as a 197kW BB PLTBm. ISE designed a 1.5 ton / h WP factory in Bangkalan Madura, Mamuju (Sulbar) 2 tonnes / h, Karangantu, Banten, and PLTBm in Ds.
