Organic Waste Crushing Machine

Biogrinder crushes and mashes organic domestic waste

Biogrinder (type RBG) is used in the processing of biomass for biogas generation. 

Biogrinder is in use in southern Germany to crush and mash organic domestic waste. The upstream substrate processing speeds up gas production in the fermenter. Overall, the biogas plant operates more efficiently and reliably.

Fermenter-friendly processing

• Enhanced uptake of nutrients for micro-organisms through intensive shredding, homogenization and defibration of the input material
• Particularly effective in the case of highly fibrous biomass
• Extraneous materials, such as soil clods and stones, are also crushed.

Greater variety of raw materials

• Raw materials that were previously difficult or impossible to decompose in the fermenter can now be processed with ease after processing in the Biogrinder.
• Wide range of applications: corn silage, grass clippings, green/organic/animal waste, sugar beet, corn straw

High energy efficiency

• Very short substrate retention times
• Nearly all the energy applied is converted into crushing capacity and not heat
• Further energy savings result from the reduced need for chopping during harvesting, reduced agitator use in the fermenter 

Stable fermentation process

• Homogenization facilitates transport of substrates
• No deposits build up in the fermenter

Continuous process

• Continuous operation simplifies technical integration of the machine into the overall plant 
• Different sized Biogrinders available to ensure optimum throughput rates for biogas plant

Future-proof investment

• High degree of flexibility when it comes to raw material selection in view of changing market conditions and legal frameworks
