The use of plant residues - straw briquette press
Nowadays, people are searching for alternatives to fuel, which has become very expensive unjustifiably. Some try to substitute it by using wind energy, solar energy, hydropower, etc.
In the past, the cheapest and most convenient raw materials for obtaining energy and heating were wood and coal, which were later replaced by oil and natural gas. Unlike eco-friendly fuels, oil and natural gas are limited resources, more costly, and harmful to the environment. Until recently, straw was used for various activities in households, such as insulation, heating, animal feed, and even making straw bricks.
However, these methods of using straw are outdated and no longer applied. Currently, cereal production is increasing, which necessitates the improvement of the sector related to the processing of plant residues. Additionally, straw poses a challenge in soil processing after harvest.
According to statistical data, after barley harvest and processing, more than 1.5 tons of waste is generated per ton of finished product. For wheat, it's approximately 2 tons of waste, and for corn, it's over 6 tons.
Until now, this sector has not been developed. As a result, straw rots in the fields, and thousands of hectares of agricultural land with leftover straw after harvest are burned, causing global pollution.
In terms of energy, the proper processing of straw can be demonstrated by the fact that 1 kilogram of cereal straw has a calorific value of 3 kWh. This means that the same amount of energy can be obtained from 3 kilograms of straw as from one liter of diesel fuel or one cubic meter of natural gas.
Natural resources like cereal straw, which are easily obtained either through harvest or procurement, are five times cheaper than the cost of energy consumption from diesel fuel.
However, burning straw bales is not practical due to low efficiency (straw has low density and relatively high moisture content) and the inconvenience of handling large volumes of straw bales.
Therefore, briquetting straw is one of the most rational methods for utilizing bio-resources, as straw briquettes are more efficient in energy production than wood briquettes.
From a scientific point of view, straw is characteristic not only of dried cereal stems but also of vegetable stems, as well as flax, hemp, and other plants without leaves, inflorescence, and seeds.
Briquetted straw can serve as a universal biofuel for heating houses, greenhouses, farms, and industrial facilities.
Briquetting straw allows for solving issues related to:
- Preservation and storage of raw materials (regardless of the season - briquettes can be stored indefinitely if kept under special conditions)
- Briquette transportation
- Automation of loading into the furnace
- Animal feed
Processing and recycling waste, as well as briquetting straw, represent a promising sector both in the domestic and international markets. The delivery and commercialization of the finished product (briquettes) are much more profitable than selling raw materials.
Therefore, our company offers briquetting solutions/technologies, including mechanical straw briquette presses with flywheel-actuated piston, pellet granulator, pellet press, air dryer, bale shredding complex, and straw baler. We also provide services such as consulting, delivery, installation of briquetting and pelletizing equipment, post-warranty service, and automation of straw briquetting lines.
Our company intervenes in the European market with offers related to the commercialization of briquette and pellet production equipment, delivery, installation, service, post-warranty support, and spare parts.
