We produce and deliver environmentally friendly heat energy


Pellets, or fuel granules, is renewable, non-polluting biofuel, the energy of which as a result of burning turns into energy of heat. Raw material for pellets manufacturing mainly consists of wood and agriculture waste which previously were put out to pasture (sawdust, chips, straw, husks and sunflower stems), and also RDF (solid domestic waste). Our partner, VIKIWOOD company, works in the field of wood processing and has high potential for manufacturing pellets from wood waste. Besides that, Banisa Energy Ukraine has its own stock of lignin, which allows creating a fuel stock for several months for each Client thus guaranteeing uninterrupted delivery of. pellets

Few Words on Pellet Fuel Properties

Pellets are one of the most power-intensive fuels. Calorific power of wood granules is 4.3-4.5 kw/kg. Such calorific value is possible thanks to low moisture content (8-10%). Releasing a considerable amount of heat, the granules thus increase efficiency of boiler rooms. Total efficiency of granules combustion is 85%-95%.

The same energy is released when burning 100 kg of wood granules and

  • 100 kg of bright coal
  • 160 kg of wood
  • 48 l of gas
  • 50 l of diesel oil fuel
  • 70 l of black oil fuel

Pellets do not require much storage space. Being compressed, they occupy 5 times less space than, for example, wood. The granules are biologically inactive, as they have underwent heat treatment, and can therefore be stored in immediate proximity to the housing, they do not self-ignite during storage, thus there is no risk of explosion. The granules do not contain spores which can cause allergic reactions in humans. 

Boilers working on the pellet fuel are fully automated. Granule loading in the fuel device and the burner flame is regulated automatically, maintaining the room temperature as set on the thermostat. It is possible to fill the granule container and to clean the boiler once or twice a week.

Boilers with properly chosen power can heat a room of any size – from small private homes to giant power plants, while saving on heating at the same time.

The primary users of fuel granules in the world currently are all developed countries: European states, Japan, USA, Canada. In Sweden, the consumption of fuel granules (pellets) annually grows approximately by 30%. The Swedish governmental program provides for pellet consumption increase to 7 million tons per year.

Wood granules (pellets) are a standard fuel type in the world, therefore there are specifications set for them. In Germany specifications are called DIN (the German industrial standard). In Europe until recently German standard DIN 51731 and Austrian standard 0-NORMM7135 have been used.

We, too, are guided by the standards accepted in Europe.


Advantages of pellets compared to other sources of energy


Advantages of wood pellets as compared to electric power

Electric power for the factories is the most expensive type of fuel. The owner spends 3-5 times more money for heating than he could if he has used pellets.
Besides, connection of the equipment requires much more permissions and documentation. Use of electric power does not secure uninterrupted operation of the factory due ro frequent switching-off.


Pellet price is stable and does not depend on instability of oil prices

Due to high cost of diesel oil fuel, heating with granules is 1.5-2 times cheaper.

Wood pellets are renewable fuel, while oil is unrecoverable. So, oil price will continue to rise.

The boiler-room operating on diesel oil fuel or black oil fuel has a repulsive odor which often penetrates into residential or office premises located nearby. Even the sure venting system does not help. While pellets have no odor.

Leak of diesel oil fuel during transportation, as well as during storage in the boiler-room creates some more problems: risk of ignition, fat stains on the floor. Pellets will never escape through the walls of the storage bunker. Therefore, the floor and the room itself will always be clean.


Gas Heating Minuses

Price. The constant rise in prices for this fuel type quite complicates calculation of heating cost even for one heating season.

High enough cost of connection to central GPS.

Poor gas quality, astable pressure in the system leads to failures of the equipment operation.

Connections and current maintenance are carried out only by certified organisations.


Advantages of Pellets vs Coal, Firewood, Sawdust, Briquettes

The engineering aspects of boilers operating on pellets allow completely automate the process of supplying granules into the furnace.

Pellets combustion in the boiler furnace is more effective than coal combustion. The amount of residue (ashes) does not exceed 0.5% of total amount of granules used. The amount of ashes formed at combustion of coal can reach 35%. In order to remove and utilize this amount of ashes, additional investments into freight transport and money for the right to utilize it in the area landfill should be spent.

The insignificant amount of ashes formed at pellets combustion can be used as a perfect fertilizer.

Wood granules are less exposed to spontaneous ignition as do not contain dust.

Coal dust formed during storage of coal, permanently eats into walls and the floor of boiler-rooms. The appearance of these premises will definitely not be clean. The coal dust can be dangerous to people suffering allergy and asthma.


Pellets, or fuel granules, is renewable, non-polluting biofuel

Enterprises using pellets do not need quotas for greenhouse gas emissions which are foreseen by the Kyoto Protocol.

During the combustion of pellets, carbon dioxide emissions into the air are 10-50 times lower than with other fuels. The same amount of CO2 is released during the decay of wood, which allows speak about pellets as about neutral fuel.

Ash formation in pellets is 15-20 times less than e.g. during combustion of coal. Moreover, such ash is an excellent fertilizer for plants.

The amount of sulphur and nitrogen is minimal within the pellet biofuel and, when burnt properly, it is virtually impossible to detect nitrogen oxide and sulphur dioxide in the fume gases.

Wood granules are classified among renewable sources of energy and therefore their production process is not harmful to nature.


The production process of pellets

The production process of fuel granules is called compressing, but it is preceded by several important stages.
At first, raw material is pre-crushed. Special chipping machines crush the prepared biomass for further drying. According to production schedules, the humidity of raw materials before compressing should be of 8-12%. Therefore, at the second production stage the half-finished pellet is being dried. Then, a hammer mill disintegrates the dried product into smaller fractions.

The next stage is water conditioning. The point is that raw materials with humidity less than 8% are badly bonded during pressing. Therefore, too dry raw materials are unsuitable. To achieve the required humidity of raw materials, a facility for water metering in the mixing tank is used, usually these are screw mixers with built-in water intakes (for soft varieties of gymnospermous wood) or vapour intakes (in cases when hardwood is compressed, such as oak or beech, as well as poor-quality or old raw materials).


When the mass is sufficiently moistened, the process of compressing begins, it being the main pellet production stage. The press can be of various designs, with a flat or cylindrical matrix. The biomass, under high pressure, is extruded through matrix’s circular holes, particles of this biomass due to lignine contained in the wood residue, conjugate, forming a solid volume and turning into granules.

Pellets, when leaving the press, are hot enough (70°-90°С) and soft. So they need to be cooled. Being chilled, granules solidify and are ready to be shipped.
At the last production stage, pellets are screened and packed. Screening is necessary for separating not compacted or broken into chips pellets. Certainly, the production is non-waste and the substandard product is simply exposed to secondary processing. Pellets can be stored for endless period, the main thing is not to expose them to excessive moistening.
