NOVELTY - Thinning wood (1) and pruned branch (2) are carbonized in a carbonization furnace (10). The obtained charcoal is ground to a fine powder coal (13) which is burned in a thermal power station (14) to obtain electrical power (16).    USE - For processing thinning wood and pruned branch to produce electrical power, and pyroligneous acid, which is used as a pharmaceutical raw material.    ADVANTAGE - The processing method is economical and causes no environmental pollution. The disposal cost in the incinerator plant is eliminated. Charcoal and bamboo charcoal are sold off as a fuel for power stations, which becomes a source of income. Installation cost and transportation cost are reduced. The pyroligneous acid provides a large source of income.    DETAILED DESCRIPTION - An INDEPENDENT CLAIM is included for processing system comprising an information center, a carbonization center (21), a thermal power station and a pharmaceutical firm (8). The information center receives information, such as the enforcement person while performing thinning and pruning, time, place and the amount of wood. The carbonization center performs carbonization of the thinning wood and pruned branch based on the information provided by the information center. The information center sends the component estimation and fine powder coal amount based on the information from the carbonization center to the thermal power station. The amount of pyroligneous acid (7) production and component estimation are sent to a pharmaceutical firm. When the process is completed in the carbonization center, pharmaceutical firm and thermal power station, the amount of operating experience of fine powder coal and income-and-expenditure report information is decided.    DESCRIPTION OF DRAWING(S) - The figure shows an explanatory drawing of an implementation of the processing method which burns coal in a thermal power station and obtains electrical power.
