Production of Biophenol, Bioformaldehyde and Wood Adhesive from Pyrolysis Liquid Products

The byproducts of biomass (slow) pyrolysis are liquid and gas products. The liquid products consist of biooil and biomass vinegar (pyroligneous acid). Biooils can be directly used as fuel with a particular burner, or can also be upgraded to the vehicle fuel. Meanwhile, if used for non-energy products, can be used for the production of green chemical or renewable chemicals such as BioFormaldehyde and wood adhesive. While the aqueous phase of pyrolysis liquid product that is biomass vinegar (pyroligneous acid) can be used for feedstock biophenol production. Previously biomass vinegar has been known for various uses such as latex coagulant, anti-termite and fertilizer. While the biophenol production process scheme of biomass vinegar as follows.
Global consumption for phenol currently reaches 20 million tons or worth 20 billion US dollars (280 trillion rupiah). Renewable phenol or biophenol can substitute phenol which has been produced based on petroleum. Excess heat and excess syngas fr…

Set Up Wood Pellets Production in Southeast Asia

Korea and Japan are the main destinations of the wood pellet market especially for producers in Southeast Asia. Korea with Renewable Portolio Standard (RPS) policy, while Japan with feed in tarrif. So the estimated needs of wood pellet of both countries reached 10 million tons in 2020 and so on. Currently most of the supply of wood pellets in Japan from Canada and for Korea in supply mainly from Vietnam. In 2019 and beyond in Japan will be importing wood pellets in large quantities because a number of power plant facilities began to operate.
Based on a number of analyzes, one of them can be read here, there was a decline in the production of woody biomass in Southeast Asia from 815.9 million tons (16.3 EJ) in 1990 to 359.3 million tons in 2020 predictions. This condition occurs due to deforestation and excessive logging (including illegal logging). The destruction of the forest is certainly a cause of concern for the disaster also needs to be solved solution as soon as possible. Refo…

Set Up Wood Charcoal Briquette Production in ASEAN Countries

ASEAN countries have large forests and various forest resources. However, there is a decrease in some countries due to irregular logging in some countries. This is why sustainable forest management is needed to maintain the biomass of forest resources. Indonesia has the largest forest area, but has declined since 1990 primarily due to illegal logging and forest fires. Malaysia has the highest number of biomass and forest growth in area ratio, while Thailand is the lowest. This could also be due to higher rainfall in Malaysia compared to other ASEAN countries, which is 2,875 mm / year, with an world average of 900 mm / year and Indonesia 2700 mm / year. For more details can be seen in table below. Indonesia and Malaysia mainly produce sawn wood and plywood, while Thailand is wood chip and particle board. Vietnam produces many sawn wood, while Cambodia and Laos consume lots of logs as fuel. Wood charcoal briquette or sawdust charcoal briquette have a very high market especially in Middl…

Heat Gasifier and Stirling Engine For Remote Villages Electric Solutions

Remote villages far from PLN's electricity network will find it hard to get electricity, especially those on small islands with limited populations. These remote villages are also generally left behind villages and still need special attention. Currently such villages are still very much found in Indonesia, ie 60% or about 50,000 villages, as a more real picture in Java with an average ratio of 3 out of 10 while in Sumatra the ratio is 7 out of 10 and Irian 9 of 10 villages enter left behind villages. One effort to give attention and develop the villages is by providing electricity for their various needs including access to information with the outside world. The availability of energy, especially electricity, also encourages them to be independent with various kinds of production.
Based on the above conditions so it takes small generators that can be operated in the remote villages. The concept of decentralization will be able to reach these areas. To run the plants easily also…

Production of Pellets and Briquettes from Waste Of Albasia Wood Working Factories

Albasia is a tree that many people planted in various areas within the forest area. It is currently estimated that the albasia plantation area is more than 1 hectare in Indonesia. Wood is the main product of the albasia plantation. The wood is processed into various products of logs, wood boards, plywood, barecore, to pallet. Albasia wood is softwood and produced from the harvest timber of the plantation is at the age of trees approximately 5 years. The centers of albasia plantations in Indonesia are centered on the island of Java and Kalimantan.
Waste from the albasia wood processing are sawdust, pieces of wood, bark and wood shavings. There are still many untapped waste and pollute the environment. The production of wood pellets and wood briquette with these raw materials will overcome environmental problems, move the economic sector from waste treatment or especially bioeconomy which is predicted to be a trend in the not too distant future. The simplest wood processing industry of…
