One potential bioenergy that has not been explored to its full is the bioenergy potential of wood processing industry waste. The wood processing industry’s waste from saw mill wood is an alternative fuel substitute for IDO or MFO which has been widely used in the wood processing industry. The calorific value of saw mill wood waste is around 2,600 -3,400 kcal / kg, because there are many cellulose, sulfur, lignin, water biomass and so on. If the use is burned, it will directly give potential environmental impacts in the form of emission gas pollution in the form of Fly Ash, CO2, NOx and CxHy. This method is considered less efficient and gives less value. This study aims to obtain renewable energy sources by converting sawmill wood solid fuel wood processing industry into clean, sustainable and high-calorie gas fuel (syngas) as well as preventing air pollution. The method used is the development of gasification process technology in the burner vesel fluidized bed reactor with a controlled, low oxygen vertical perforated blade installation, resulting in Syngas. Through the gasification process, saw mill wood waste can be converted into gas that is more flammable with higher calorific value and environmentally friendly (clean energy). Syngas technology will be designed based on the principle of imperfect / oxygen-poor combustion at temperatures of 300 – 500°C, inside the closed vesel, so that the gas formed is CO, H2 and CxHx gas. The output is the development of gasification process technology that produces bioenergy syngas can be used in the substitution of boiler fuel for an environmentally friendly wood drying process.

Harvesting teak in Java always causes wood waste in the forest. The objectives of this research were to identify the shape of wood waste generated from teak harvesting activities and to determine their recovery and residual factors. The research was conducted at teak forest of Stated Owned Company (Perum Perhutani) at Banyuwangi East Java with the sampling intensity of 10 % using whole tree method. Measurement of wood waste was performed at thinning and clearcutting compartment of teak stand. The result of the study showed that the shapes of wood waste consisted of broken stem, decay wood, short trimming, branch and twig , stump, and irregular wood shape. The recovery and residual factors of the teak harvesting utilization were 79.61 % and 20.39%, respectively. Most of the wood waste were utilized by the local community for energy sources. Key words: Recovery factor, residual factor, teak, wood waste

The present work reported the adsorption of Cr (VI) from aqueous solutions on activated carbon prepared from teak wood waste. Biomass from teak wood were taken out and pulverized in a micro-pulverizing mill. The powder thus obtained was activated with 40% H3PO4 and carbonized at 600 °C for 1 hour in an inert atmosphere. Physico-chemical characteristics such as  functional groups and surface morphology of the activated carbon were analyzed using FTIR spectroscopy and SEM analysis respectively. Batch adsorption experiments were performed to investigate the effects of Cr (VI) concentration, carbon dose, pH and time. The maximum adsorption capacity of Cr(VI) was found to be 1.5 g/L at pH 3 and temperature 30±1 °C. The Freundlich adsorption isotherm best represented the equilibrium data and a pseudo-second order relation represented the adsorption kinetics.

Biomass gasification is influenced by many factors, such as temperature, air equivalent ratio, steam/carbon mole ratio, etc. Mostly, these factors are affected each other during the gasification process. It is needed to study the gasification characteristics and the action mechanism of each factor. Firstly, a moving gasification bed is adopted to investigate the biomass gasification characteristics and mechanism in this paper. The pine sample is evenly distributed in a long tray and be sent into the furnace at a certain speed. At the same time, with a furnace temperature, linearly increasing from the entrance to the center of the furnace, the pine sample can be gradually heated up. Based on these, the experimental studies of pine gasification on different ER (air equivalent ratio), S/C (steam /carbon mole ratio) and the temperature T are carried through in this paper. The gas production rule and low calorific value of the syngas have been gotten with heating rate 25°C/min. At last, this paper gets the kinetic parameters of air gasification with different ER.
