Abstract

Large scale plantations of Eucalyptus hybrid bave been raised in the country in degraded forests, road side land, canal banks, community lands etc., and it is expected that substantial quantity of wood would be available in future for various wood processing industries. The wood waste like bark, tops, thinnings, twigs etc., which accounts considerable volume of a tree would also be available which largely find use as fuel. Therefore, the suitability of unbarked Eucalyptus hybrid including tops, thinnings, twigs etc., was studied for hardboard manufacture. It was established that unbarked Eucalyptus hybrid is a suitable raw material for hardboard manufacture. The standard hardboards could be prepared with additive after heat tempering and tempered boards after oil tempering only using the semi-chemlcal process.

Abstract

Bamboo is generally stored in outside locations in wood based industries in our country. The storage period extends from a few weeks to about nine months. During this period the bamboo is attacked by various wood destroying organisms, it is believed that more than 20 per cent of it is destroyed during outdoor storage. Various chemical treatments have been suggested for controlling the decay in bamboo/wood during outdoor storage. The paper deals with the use of three cheap indigenous chemical preservatives for treatment of bamboo during outdoor storage for a period of twelve months. The economic feasibility of the treatment has also been discussed. The pentachlorophenate (Sodium Salt) was found to be most economical and effective.
