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.

The practice of burning and stockpiling to reduce wood waste from the wood processing industry is not in line with the demands of clean production, environmentally friendly and sustainable industries. Pyrolysis technology can be used to produce bioenergy from wood waste. The temperature and the time of the pyrolysis process, the water content of materials, and the content of different yields between types of wood waste affect the bioenergy products produced. This study was aimed at determining the effect of wood waste form and condition on the quality and quantity of liquid smoke, tar, and charcoal. A Completely Randomized Design with two factors of treatments, i.e., waste forms and the drying process, was applied in this research. The results showed that the condition and shape of the material affect the volume of liquid smoke and the weight of the charcoal produced. The condition of the material without drying with high water content and the shape of the chunks produce more liquid smoke with an average yield of 191.14 mL and 186.37 mL, while the charcoal produced is higher in the condition of the material with drying and shaved form at 125.83 g and 115.62 g. The results of the test characteristics of grade 1 and 2 distillation liquid smoke meet the Japanese liquid smoke quality standards with phenol levels in the range of 26.66-35.94 mg GAE/mL sample and acidity levels of 16.91-58.9%. Keywords: Char; liquid smoke; pyrolysis; tar; wood waste.   ABSTRAK Praktik pembakaran dan penimbunan untuk mereduksi limbah kayu dari industri pengolahan kayu tidak selaras dengan tuntutan produksi bersih, ramah lingkungan dan industri berkelanjutan.

One of the growing industries in Indonesia is the woodworking industry. Wood waste is waste or parts of the wood that no longer has economic value but may still be used at different processes and times. The woodworking industry produces wood waste in 22% wood scraps, 8% wood chips, and 10% sawdust. The fundamental problem in the woodworking industry at Sindangmekar Village was the lack of understanding and practice in wood waste management. Through the socialization of wood waste management as planting media, community service aims to increase knowledge regarding wood waste management. In addition, it can improve practice to manage sawdust as a planting media. Furthermore, it has economic value and becomes one of the solutions to financial problems during the COVID-19 pandemic. The socialization presented materials related to wood waste management and practiced making planting media from sawdust. Thirty participants attended this activity. There was a significant increase in pre-and post-test scores after socialization. In conclusion, socialization regarding wood waste management increases knowledge levels in wood artisans and youth alliance at Sindangmekar Village. In addition, participants can manage wood sawdust as a planting medium. As a result, it can increase the selling value of wood waste, and the surrounding environment becomes clean and healthy.

Abstract Grajen Batik is batik which coloring process uses natural dyes from grajen (sawdust) waste. Batik Grajen was developed by batik artisans in the Bulakan area, Sukoharjo, Central Java. The development of Batik Grajen is ecologically alluring since the Bulakan community processes sawdust from the sawmill industry into eco-friendly batik dyes. Sawdust (grajen) waste is used as batik dye because of the pigment contained. The dyes produced are safer and more eco-friendly than synthetic dyes. The effort made by the Bulakan community through Batik Grajen products is a creative solution to respond to environmental problems, especially waste problems that can be recycled into creative products with economic value.

Abstract The article examines the current state of wood waste recycling in the interests of ensuring sustainable development and minimizing the impact on climate change. Classification of wood waste based on the stage of the life cycle of a wood product has been carried out. The problem of organization of wood waste disposal and processing is relevant both directly in the forest industry and in the process of using wood since this leads to the preservation of primary wood material and significantly reduces the volume of deforestation. During the study methods of wood waste recycling and options for complex recycling have been identified. A wood waste recycling scheme which includes such stages as collecting wood waste, deep wood processing and involvement in secondary circulation has been developed. An econometric analysis of correlation between current environmental costs and indicators of economic activity associated with the use of wood waste on innovative basis has been carried out. It has been concluded that there is a tight relationship between the costs of environmental protection and the selected factors. The research results can be used in the development of wood waste recycling schemes by various economic entities of timber and woodworking sectors.

Energy production from previously unused wood waste, which is produced by mining and manipulation in forestry, wood processing plants and in plants and also more efficient energy recovery firewood in the total amount of about 500 000 t, can annually replace the same amount of brown sorted coal. This has a significant national- economic importance in saving precious fuel but the financial effect greatly exceeding the environmental- ecological benefits resulting from the reduction of environmental burdens, exhausts and incombustible solid residues. These are only a few advantages and also the reasons why it is necessary especially at present days to deal with biomass and wood waste as well. The article therefore outlines a comparison of the previous use of this energy source as well as its possible future development.

The South of Algeria is known for these immense sand dunes, which cover part of its territory (Sahara). The main objective of this study is the recovery of sands dune and wood waste (sawdust). The latter, which constitutes a potential source of several environmental and economic problems. The objective of this present work is to characterize the physico-mechanical properties at a young age of a dune sand-based mortar lightened by wood waste and to examine the suitability of using it for various applications in the construction of buildings. The improvement of the characteristics of these sands, which essentially formed of sand untapped to date and with the sole aim of enhancing this national sand wealth. The formulation of the mixtures is based on the substitution of dune sand by sawdust, at different weight contents 0, 10, 20 and 30%. The quantity of cement is fixed at 450 g. The results obtained show firstly that the introduction of sawdust improves the characteristics of the mixture (grain size tends to be spread out, reduction in densities), and secondly the physico-mechanical characteristics, especially at 30% substitution (reduction absorption by total immersion of 20.50%, porosity of 28.32%, wet density of 1.73% and dry density of 14.94% and increase in tensile strength of 61.43% and in compression of 63.87%). The effect of sawdust on the relationships between the properties of mortars was clearly noted either for the relationships between early strengths or between compressive and tensile strengths.

Biogas is one alternative to replace the irreplaceable energy source that has begun to diminish its existence. The raw materials for biogas manufacture are renewable biomass, usually using plantation waste, agriculture, and livestock. Using biogas can also reduce environmental pollution. One of the agricultural waste that has great potential to become the raw material of biogas is teak sawdust. Wood processing industry in Indonesia quite a lot, but wood has a high lignosesluosa content, so it needs the right method to process it. With the delignification of lignin levels on teak sawdust will decrease. Wood sawdust is soaked using NaOH for 1, 2, 3, and 4 days with 4% w / v concentration. The lowest lignin and hemicellulose content was 25.79% and 87.9% in pretreatment for 4 days, while the highest cellulose level was 57, 34%. The accumulated volume of biogas at 1 day pretreatment, ie 709 ml / g TS. Gcms shows the enlarged peak area of methanamine, N-methyl from before pretreatment. The fastest biogas formation (λ) in 4 days pretreatment, 1.60403 days and the largest constant A and U variables at 1 day were 914.5903 ml / g TS and 34.59765 ml / g TS.

To reduce deforestation and illegal logging several international initiatives have been carried out. Recognition of SVLK existence, among others, is through Forest Law Enforcement, Governance and TradeVoluntary Partnership Agreement (FLEGT-VPA) and Illegal Logging Prohibition Act (ILPA), which are proof of Indonesian Government’s commitment to improving forest governance. Sistem Verifikasi Legalitas Kayu (SVLK) regulates compliance from forest management and timber trade aspect. Scope of SVLK audit covers from upstream to downstream forest governance, one of which is sawmill industry. Fulfilling the legality aspect of sawmill industry is mandatory in SVLK. SVLK also analyses wood traceability and sawmill activities in the industry. One of indicators used is sawn timber recovery of sawmills. The research was conducted using literature studies, descriptive analysis and comparative analysis of secondary data and regulations related to SVLK. Case study used as research object was Penggergajian Kayu (PK) Rimba Sari sawmill industry with production capacity of <6,000 m3/year in Banyumas. PK Rimba Sari generates of 59.34% sawn timber recovery. The study shows that there is potential for utilization of wood waste amounting to 40.66%. So far, wood waste is only used for direct sales but no processing has been carried out yet. The objective of research is to analyze the optimization of sawn timber recovery concerning legality aspect of company as a form of compliance with SVLK scheme. This study concludes that researchers recommend an alternative use of wood waste as part of a sustainable industry and clean production.
