Changes in organic matter were mainly affected by the type of reagent use and the dosage, with minimum influence of exposure time and dilution. Changes in pH may limit the application of chemicals. Increase in biogas production with a combination of CaO and PAA, and separate application of PAA and CaO was 156.5%,39.1% and 26.1% for cow manure and 125%, 137.5% and 37.5% for maize straw, respectively, compared to unpretreated samples. Pretreating cow manure with the aforementioned reagents does not increase the profitability of a biogas plant due mainly to the increase in operational costs from the intensive use of chemicals.
