(replanting)

120 small logs Ø<10 cm
big and medium logs are used as fire wood in brick and roof tile industry: price 20,000 – 30,000 IDR/m³
Logging residues Sumatera, Kalimantan 4.5 19  
Sawn timber residues Sumatera, Kalimantan 1.3 13 Residues of the factories are often used as fire wood by local communities, residues available for free
Plywood and veneer production residues Kalimantan, Sumatera, Java, Irian Jaya, Maluku 1.5 16 Residues are generally used, yet
Sugar residues Java, Sumatera, South Kalimantan Bagasse: 10
cane tops: 4
cane leaves: 9.6
78 Bagasse is generally used in sugar factories (90 %)
The use of cane tops and leaves needs to be investigated

bran 2.5
stalk: 2
straw: 49
150 Stalk and straw are generated at the field and generally burnt, in some areas used for feeding or raw material for paper industry
Husks often burnt uncontrolled
Coconut residues Sumatera, Java, Sulawesi Shell: 0.4
husk: 0.7
7 Residues are generated decentralised and usually left on the plantation field Largely used as fire wood and for the production of charcoal
Palm oil residues Sumatera
new areas: Kalimantan, Sulawesi, Maluku, Nusa Tenggara, Irian Jaya
Empty fruit bunches: 3.4
Fibres: 3.6
palm shells: 1.2
67 Palm shells and fibres are common fuel sources, EFB are generally incinerated
