THE BIOMASS ENERGY UTILIZATION OF THE TIMBER OFFCUTS IN FOREST OF NAGANO PREFECTURE

The biomass energy utilization of the timber offcuts based on the premise of carbon offset in nagano prefecture Part 2

Abstract

In this thesis, the abundance of the timber offcuts of felling per one year was calculated as a test, and the amount of CO₂ emission reduction when those were burnt in substitution for fossil fuel was calculated in the forest of Nagano prefecture. A CO₂ emission reduction effect when the moisture in the timber offcuts was reduced was calculated as a test. Following results were obtained by researches.
1. The amount of the timber offcuts felling per one year were quite 1,006,000 m³/year in the forest of Nagano prefecture.
2. When one log is burnt, The amount of CO₂ emission reduction when it is burnt after a log was left in outdoor depository has more quite 17 kg-CO2/log than when it is burnt as soon as it was felled
