For many years, straw was regarded as a waste product from the agricultural sector, but today it is recognized as a valuable resource. In the past, straw was either burned in the fields or left unused, but now it holds significant value in several areas, including as an effective ingredient in biogas production. By using finely milled straw in biogas reactors, the fermentation process can be accelerated and optimized, making it a key resource in renewable energy.

Using straw as a catalyst in biogas production is not just a smart choice; it is a responsible one for the following reasons: it’s the responsible choice for the following reasons:

By straw for other purposes reduces agricultural waste and minimizes both landfill burden and emissions from burning, leading to enhanced efficiency.

Straw is a renewable resource, where the CO2 released during decomposition is offset by the carbon absorbed during its growth, making straw CO2-neutral.

Straw enhances biogas production, thereby generating more clean energy from the same base materials.

Increased biogas production with straw will reduce our dependence on fossil fuels, contributing to a more sustainable and cleaner future.

Linka Energy and EUROmilling provide a comprehensive solution that includes all the necessary components and technology to efficiently convert straw bales into biogas. Our integrated solution includes:

• • Overhead Crane: Fully automated delivery of straw bales using a straw crane, with no operator assistance required.
  • Straw conveyor system: fully automated straw conveyor system.
  • String remover: Automatically removes strings from straw bales.
  • Straw shredder: Effectively shreds the straw bales for further processing.
  • Stone trap: Captures and removes unwanted elements such as stones, metal, and other contaminants.
  • Pre-grinding mill: Grinds the straw, making it suitable for both wind sieving and subsequent fine grinding.
  • Wind sieving: Removes additional foreign materials to minimize wear and protect the fine grinder.
  • Fine-grinding mill: Ensures the straw achieves the desired fine particle size.
  • Pre-mixer (mixing tank): Mixes the straw with slurry to make the blend pumpable and ready for further transport to the reactor tank.
  • Control and Monitoring System: monitors, optimises, and safeguards the operation to ensure efficiency, safety, data collection, and remote control.

This is a solution designed for industrial plants, with a strong emphasis on uptime and low maintenance costs.

The solution from Linka Energy and EUROmilling complies with all regulatory requirements. The customer and our team of engineers and project managers work closely together on the following:

• Conducting a risk analysis for safety purposes.
• Preparing CE documentation.
• Developing an ATEX risk assessment and providing proposals for relevant solutions with associated documentation.
• Implementing a fire suppression system to enhance safety.

Our “Straw to Biogas” solution offers numerous advantages:

• • Short conversion time: Effectively converts straw powder in the reactor.

• • Moisture resistance: the The system can handle straw with a high moisture content.

• • Automated operation: Requires minimal handling of straw bales, as the entire system operates automatically.
