Briquetting and granulation – an efficient method for waste processing
Briquetting is a process in which various materials are compressed into a compact, solid form — briquettes. This is done to efficiently process or fully utilize waste, as well as to make it easier to transport and store. Briquettes can be produced from a variety of agricultural residues, such as straw, hay, and oilcake, as well as from paper, polyurethane, sawdust, and other materials.
Granulation is a similar, yet slightly different process, in which the material is crushed and then compressed into small, uniform granules. This method is especially popular in biomass and animal feed production, as granules are easy to dose, simple to store, and retain high energy value.

Which press to choose?
The choice of press depends on several factors. It is necessary to consider the type of material to be processed, the required production capacity, the level of automation, and the budget.
For dry and homogeneous materials such as straw, hay, or sawdust, presses with a high compression ratio are suitable, producing dense and durable briquettes. For wet or mixed waste, it is more advisable to choose presses with a pre-drying system or combined models capable of handling different types of raw materials.
It is also important to take production needs into account: small and medium-sized enterprises can use compact semi-automatic units, while large-scale operations may benefit from investing in fully automated lines with high throughput and minimal personnel involvement.
Choosing the right press ensures not only efficient production of briquettes or granules but also optimizes raw material usage, energy consumption, and equipment operation costs.
