Utilization of Vegetable Waste: Straw and Straw Mulch
In contemporary society, individuals are exploring alternatives to fuel due to unjustifiably high prices. Some are turning to wind energy, while others are harnessing solar and hydro energy.
Historically, wood and coal served as the most economical and convenient resources for energy and heating, later supplanted by oil and natural gas. In contrast to renewable energy sources, oil and natural gas are finite, expensive, and detrimental to the environment. Until recently, straw has been utilized for various domestic purposes, including insulation, heating, maintaining warmth for livestock, and producing straw cereals.
However, these traditional methods of straw utilization are becoming obsolete. As cereal production continues to rise, the sector focused on processing vegetable waste requires significant enhancement. Concurrently, straw poses challenges for post-harvest soil processing.
Statistical data reveals that more than 1.5 tons of residues are generated for each ton of finished product produced from barley, approximately 2 tons from wheat, and over 6 tons from maize.
To date, this sector has not experienced adequate development. Consequently, straw often decomposes in fields, while vast areas of farmland designated for straw storage post-harvest have been subjected to burning, resulting in pollution—an escalating global issue.
From an energy perspective, the potential of effective straw processing is striking: one kilogram of cereal straw yields an average calorific value of 3 kWh. This indicates that the energy produced from 3 kg of straw is equivalent to that derived from 1 liter of diesel or 1 cubic meter of natural gas.
It is important to note that natural resources, such as cereal straw, which can be easily sourced through harvesting or procurement, will often still be five times more expensive than the energy derived from diesel fuel.
Burning straw bales is impractical due to their high energy consumption, low efficiency (due to the low density and relatively high moisture content), and the cumbersome volume of straw bales.
Therefore, straw briquetting emerges as one of the most effective methods of utilizing bio-resources, with straw briquettes proving to be more efficient for energy production than wood briquettes.
Scientifically, straw encompasses not only the dried stalks of cereals but also those of vegetable stalks, such as flax and various plants devoid of leaves, flowers, and seeds. Brushing straw has the potential to serve as a universal bio-fuel for heating residential properties, greenhouses, farms, and industrial facilities.
The brushing of straw addresses several key issues:
- Storage and preservation of raw materials (the storage duration of briquettes can be indefinite when stored under optimal conditions, regardless of the season).
- Transportation of fuels.
- Automation of the furnace operation.
- Animal feed production.
Waste processing, recycling, and straw briquetting represent a sector with significant potential in both domestic and international markets. The distribution and commercialization of finished products (briquettes) is markedly more profitable than the sale of raw materials.
In this context, our company provides innovative briquetting solutions and technologies, including a straw briquetting press, a mechanical piston-driven briquetting press with a flywheel, pellet granulators, pellet presses, aerodynamic dryers, bale chopping complexes, and straw choppers. Additionally, we offer services such as consultation, delivery, installation of briquetting and pelletizing equipment, post-warranty support, and automation of straw briquetting lines.
Our company operates across the European market, offering the sale, installation, and service of briquetting and pelletizing machinery, alongside post-warranty support and spare parts.
