The poultry slaughter industry's substantial water usage and wastewater generation necessitate effective wastewater management strategies. This study explores the optimization of autoclave pretreatment and inoculum to substrate ratio (ISR) for improving the anaerobic digestion (AD) of poultry slaughterhouse wastewater (PSWW). Using response surface methodology (RSM), optimal conditions were determined to be a pH of 11, a pretreatment time of 60 min, and an ISR of 2.

In recent years, anaerobic digestion (AD) has gained popularity as a practical method for generating clean energy and efficiently managing organic waste. However, the effectiveness of the reactor is compromised by the accumulation of ammonia, acids, and nutrients, leading to inhibition and instability. Because of its adaptability, biochar (BC) has sparked a substantial interest in biogas production and can be created by charring biomass and waste materials.

Rice straw (RS) has been burned in open fields in many countries, which is a growing environmental concern. Anaerobic digestion (AD) of RS is one of the sustainable alternatives to open burning of RS for converting the biomass into methane, carbon dioxide, and digestate for use as agricultural manure. The present study evaluates the RS generation, use patterns, and greenhouse gas emissions from open field burning and the AD of RS.

India is an agrarian country producing a large amount of rice straw as an agricultural residue. These residues are burnt openly leading to severe environmental pollution and health hazards. Among several options available, anaerobic digestion of rice straw into biomethane gas and digestate is a promising technology.
