A.C. Shropshire, Digester Instability – Case Study
A.C. Shropshire, Digester Instability – Case Study
A.C. Shropshire support the food industry by disposing of surplus production. The non-animal by-product waste is reprocessed to high quality alternative animal feeds and organic material food waste is processed through an Anaerobic Digestion (AD) plant. The output of which is 3.2 MW of electricity from biogas and bio fertiliser for farms.
Challenges:
Challenges:
Shropshire’s were experiencing issues with the viscosity of its digestate leading to incomplete AD processing.
Resulting in:
• Higher power consumption
• More stoppages and maintenance
• Larger volumes of dry residual solids to be removed
• Lower grade liquid fertiliser
• Fluctuations in biogas yield
Solution:
Solution:
After taking digestate samples and completing a production lifecycle analysis report, Alps Ecoscience proposed a solution incorporating waste pre-treatment and patented reactor additives which:
• Improved the solubility of waste matter
• Increased the overall rate of digestate decomposition
• Reduced the volume of residual solids

Commercial benefits:
Alps Ecoscience delivered a solution that used no more plant power, produced more gas, higher quality fertiliser and a lower volume of dry waste (volatile solids basis) left in the reactor after the AD process by more than 20%. The reduction in residual solids alone increased throughput, enhancing A.C. Shropshire’s overall organic loading rate (OLR) by over 40% and providing greater than a 30% increase in revenue.

A lab test is one of the most effective ways to better understand an AD plant’s current performance and its full potential. If you’re uncertain of where your AD production can be improved why not request one of our free lab tests. Our biologists with analyse a sample, benchmark it and highlight available improvements and our consultants can suggest a managed service plan.
