Starch processing — from cassava, potato, corn, and wheat — generates large quantities of highly concentrated wastewater rich in starch residues, sugars, and proteins. M.M.BIO POWER designs specialized biogas plants that efficiently digest this high-strength effluent, converting a costly waste management problem into a steady supply of clean, renewable energy.
How the Biogas Process Works at Starch Mills
Our reactors are optimized for the rapid biodegradability of starch-based waste. The starchy effluent is fed into high-efficiency anaerobic digesters where specialized microbial consortia break down the carbohydrates and proteins, producing methane-rich biogas while dramatically reducing the pollutant load before final discharge.
Handles starch-rich slurry, process water, and wash effluents
Produces high-methane biogas suitable for boilers and gensets
Achieves up to 90% COD reduction in a single-stage process
Effectively manages high suspended solids from starch residues
Prevents foul odors from untreated starch wastewater
Provides nutrient-rich digestate for use as organic fertilizer
Key Benefits for Starch Manufacturers
For starch mills that operate large boilers and dryers, biogas from their own wastewater represents a significant internal energy source that directly offsets fuel costs and improves overall plant profitability.
Converts high-volume wastewater into a consistent energy asset
Directly fuels steam boilers and drying operations with biogas
Eliminates costly effluent transportation and treatment charges
Ensures consistent compliance with pollution control board standards
Strengthens sustainability credentials for export-oriented starch producers
