Description

We estimated the CO22 reduction amounts of recycling pruning waste which is produced in massive quantities under the maintenance of trees planted in cities, like street trees. In addition to that, we compared the CO2 reduction amounts with the case of disposal by burning and using the heat for heat supply and power generation at a garbage processing plant, which is a normal way for pruning waste. We selected the various ways of recycling pruning waste, i.e., generating heat and electricity by burning, compost, charcoal, pellets, chips, gasification, biomass ethanol, as normal ways to make effective use of woody biomass. As a result, it showed that all recycling ways except a few cases of charcoal reduced CO2emission compared with disposal by burning, and all the recycling in case of using the products as alternative sources of energy reduced CO2 emission compared with disposal by burning and using the heat.
