Utilization of coconut timber from north Sulawesi, Indonesia. Part 1: Durability
1994 - IRG/WP 94-30044
Coconut timber from non-productive plantations is a byproduct of an agricultural crop and, by the same token, constitutes a renewable resource which may serve as a complement to or, at least in part, as a substitute for traditional timbers in local markets. Its more extensive utilization is expected to contribute to the conservation of tropical rain forests. Export of coconut timber and/or wood pr...
Utilization of coconut timber from north Sulawesi, Indonesia. Part 2: Treatability
1994 - IRG/WP 94-40025
Under tropical conditions coconut wood is quickly degraded by mold and blue stain fungi. Low density wood in ground contact is commonly decomposed by wood destroying fungi within a period of only a few months, higher density wood from the outer stem regions within 24 to 30 months (MOSTEIRO, CASIN, SERIBAN 1976; McQUIRE 1975). Moreover, according to McQUIRE (1975) green wood of lower density is hig...
Preservative treatment of green timber by soaking in ammoniacal copper borate
1984 - IRG/WP 3292
Freshly sawn boards of radiata pine sapwood were preservative treated by soaking in ammoniacal copper borate. Optimum schedules were obtained by partially seasoning the boards for one week prior to treatment. This aided the absorption of preservative and reduced the required soaking time to approximately 2 hours. Complete boron penetration was obtained after one week of block storage under cover a...

The potential use of impregnated coconut wood for power line poles in rural areas of Java
1980 - IRG/WP 3130
Electrification of rural areas in Java needs thousands of power line poles which are relatively cheap in price, but have adequate strength and are fairly durable. A choice of wood species is available in the country. One alternative is coconut wood found in abundance in the villages. This may give a solution to Java's needs since supplies are readily available almost everywhere. Based on ...
Decay resistance of coconut and rubber woods. Alternative wood species from Ghana
2006 - IRG/WP 06-10596
With the expanding local and world wide demand for tropical timbers, there is increased interest in the suitability of lesser–used timber species as alternatives for the forest based industries in order to ensure sustainable forest management. In the forests of Ghana, there are quite a number of timber species that are lesser known and have not been adequately used due to the absence of informat...

Durability testing of coconut shell according to ENV 807
2011 - IRG/WP 11-10761
Coconut shell was tested in the laboratory according to the European standard ENV 807 with three different soil types: compost soil, brown rot/soft rot rich soil and white rot/soft rot rich soil. Mass losses between 14 and 16 % were achieved with all three soils, indicating that the decay type is of little importance in the degradation process. Somewhat higher mass losses, 19-22 % were obtained fo...

Coconut lumber for wood decks (Cocos nucifera L.): decay resistance against Basidiomycetes fungi
2012 - IRG/WP 12-10784
Since a couple of years, manufactured products of coconut wood for outdoor uses like wood decks have been proposed on the European market. These are presented as an alternative for traditional tropical timbers. In the past, coconut wood was neglected and burned for sanitary reasons and lack of interest at industrial scale. Plantation coconut trees at end of production of copra constitute a renewab...

Coconut shell pyrolytic oil as wood protectant against biodeterioration
2014 - IRG/WP 14-30648
Extensive research on various plant and microbial extracts has been conducted as an alternative to using synthetic or inorganic chemicals for wood protection. Development of effective and low environmental impact products and technologies for wood protection is imperative. In the present study, the efficacy of coconut shell pyrolytic oil as a wood protectant is analysed in terms of its antifungal,...

Shells of Coconut and their Durability against Termite Attack
2015 - IRG 15-10853
All tropical and subtropical areas of the Earth are inhabited by termites. In climates with moderate temperatures, they occur less frequently. Especially wood and non-wood materials that grows in tropical areas and used there in timber constructions and woodworking, wood durability and protection against termites should be researched. This paper reports findings from an experimental “AW011” la...
