Pini Kay briquettes (often called “pini-kay”) are one of the most common types of solid biofuels based on wood waste. They are produced from sawdust and small wood fractions using high-pressure pressing and short heat treatment, which helps stabilize the shape and improve performance characteristics.

Raw materials: what exactly is taken for pressing
The basis is wood sawdust, shavings or other crushed fraction obtained during wood processing. The quality of the raw materials affects the ash content, combustion stability and strength of the briquettes. Usually, the waste is cleaned of impurities (metal, sand, corrosive particles) and brought to the desired fractional composition.

Sawdust preparation and adjustment to the required parameters
Before pressing, sawdust can be dried to optimal humidity. Excessive moisture complicates the pressing process, and too dry raw materials “set” worse during molding. Next, the material is fed int ... Read more »

Pini Kay briquettes are a popular type of solid biofuel made from compressed wood particles (often from woodworking waste). They are easily recognized by their characteristic shape: the briquette usually has a “carbon-like” or multifaceted structure, due to which the flame and smoldering are distributed more evenly.

In everyday life, Pini Kay is chosen for heating rooms and for fireplaces, as well as for use in stoves, if the system is designed for solid fuel. The main idea is to get predictable combustion without unnecessary surprises, which often happen with firewood of different quality.

What is Pini Kay
Unlike firewood, briquettes are a homogeneous product with standardized parameters. They are produced by pressing wood mass under pressure, and the shape of the briquette itself helps to maintain draft inside during combustion. The result is more stable smoldering and uniform burning throughout the mass.

Oak wood is known for its thermal and energy properties, which make it one of the most efficient types of wood for heating. The main reason for its high coefficient of performance (COP) is its density and thermal energy per unit volume.

Key factors affecting the efficiency of oak wood:

1) High specific heat: Oak wood has a high density, so one cubic meter of dry oak wood contains more heat than lighter species. This means that less wood is needed to reach the same temperature, but with a higher thermal output.

2) Low moisture content after drying: The optimal moisture content of oak wood is usually around 12–20%, while raw wood can contain a significant amount of water. Lower moisture content means less energy is spent on evaporating water during combustion, which increases the purity and duration of the flame.

3) High combustion temperature: due to its dense structure, oak wood provides stable and long-lasting combustion with a high temperature ... Read more »

Ukraine is gaining significant importance in the fuel briquette market due to efforts to diversify raw material supplies and develop local wood and production waste processing. Briquette production is becoming an important element of energy independence and reducing heating costs for the population and small businesses.

The main raw material sources are wood waste, chips and dust, as well as some types of forest scrap. In the context of decreasing costs of traditional fuels, briquettes remain competitive due to ease of storage and transportation, as well as high thermal price.

Both small home producers and medium-sized enterprises with a full production cycle operate in the Ukrainian market. The main advantages for producers are the use of local raw materials, support for energy efficiency programs and the possibility of exporting to neighboring countries within the European Energy Space.

The state and regional administrations actively stimulate the industry ... Read more »
