Scenarios of Forest Waste Utilization

Forestry wastes in Indonesia is very large amount and need to be utilized optimally. There are currently largely untapped. Multiple scenarios are proposed according to the characteristics of the forestry wastes, market needs and technological processing.

Biomass densification technology such as pelleting and briquetting is one interesting scenario to be implemented. Pellets and briquettes visually distinct because of its dimensions. The dimensions of wood pellets with a diameter varying between 6 and 25 mm and an average length is around 40 mm, while the diameter of its products if more than 25 mm is referred to as briquettes. By utilization of forest waste into briquettes is more advisable, because the size of the particle from size reduction, moisture content, and ash content of less restrictive requirements in briquette making. As for pellets particular A1 class  pellets (premium pellets) must use stem wood and do debarking. A1 class pellet or premium pellet are pellets with the lowest ash content and high calorific value. But if only for the production of quality standard pellet is not a problem. Pellets as well as briquettes can be for almost any industrial consumption as an environmentally friendly fuel substitution of coal.

However if the source location of the forestry waste is close to industries that require a lot of fuel such as cement plants, power plants and so on, then the forest waste can be directly chipping (reduced in size to the size of a few centimeters) to be directly used to fuel the industry.

Whereas if forestry waste sites are also still lack electricity or need other sources of energy or heat, then another better way is to use continuous pyrolysis technology. With this technology will produce products such as charcoal, biooil and syngas, which three can be used as an energy source. Charcoal can be sold to cement plants or power plants as fuel or increase soil fertility with enriched various nutrients to soil. Then charcoal for this application commonly called biochar. Biooil can also directly as fuel although only about half the calorific value of diesel oil and methane-rich syngas which is the excess of the portion used for the pyrolysis process itself, so that one can be used for power generation more easily with Internal Combustion (IC) engine as a gas engine generator.

Carbon Positive, Carbon Carbon Neutral or Negative?

Greenhouse gases from burning fossilfuels have caused the Earth's temperature to rise. Increasing the temperature of the earth or global warming causing numerous disasters due to climate change in a number of places on earth. When greenhouse gases not controlled then the result of damage to the environment of the earth will be more severe. Therefore, efforts were made to reduce greenhouse gases as the cause of environmental problems. In general, there are four common scenarios to prevent the global warming effect of CO2 in the atmosphere gradually, namely: 1.increasing the efficiency so the fossil fuel consumption decreases, 2.mix of renewable fuels with fossil fuels so that fossil fuel consumption has also decreased, 3.substitution of fossil fuels with renewable fuels 4.and the absorption of CO2 in the atmosphere so that the concentration of greenhouse gases can be reduced. Here are some basic terms related to the above problems. Based on the origin and the effect that CO2 in the atmo…

10 Advantages By Making Energy Plantations for Wood Pellet Production

Assuredness of supply of raw materials is one of the key factors of business success in the wood pellets. There are two ways to obtain raw materials commonly done today: a. Buying from the owner of source of raw materials. b. Producing its own the availability of raw materials. While the 3rd way and there is still few for business owners make wood pellets is by mix way, which is partly provide by their own of raw materials and some rest buy from the other source of raw materials.
While examining at the types of biomass raw materials there are two kinds, namely : a. Woody biomass b. Non-wood biomass such as agricultural wastes (empty fruit bunches of palm oil trees, corn cobs, rice husks and so on). Currently woody biomass remains a priority to be products of wood pellets as a number of advantages over non-wood biomass which is generally an agricultural wastes, are included in the category of biomass pellets or agri-waste pellets. The comparison between wood pellet and biomass pellet …
