We have the challenge of compressing the gas produced in Nigeria.
Dear Admola Ajayi,
Very Interesting Topic for Ph.D, My heartily Best wishes,
This study assessed the anaerobic co-digestion of food waste and cattle manure, in order to identify the key parameters that determine the biogas and methane yield. Results of both batch and semi-continuous tests indicated that the total methane production is enhanced in co-digestion, with an optimum food waste (FM) to cattle manure (CM) ratio of 2. At this ratio, the total methane production in batch tests was enhanced by 41.1%, and the corresponding methane yield was 388 mL/g-VS. In the semi-continuous mode, the total methane production in co-digestion, at the organic loading rate (OLR) of 10 g-VSFW/L/d, increased by 55.2%, corresponding to the methane yield of 317 mL/g-VS. Addition of cattle manure enhanced the buffer capacity (created by and VFAs), allowing high organic load without pH control. The C/N ratio and the higher biodegradation of lipids might be the main reasons for the biogas production improvement.
After conducting an in-depth life-cycle analysis assessing the environmental impact and economic benefits of managing both manure and food waste generated at a dairy farm, scientists conclude that anaerobic co-digestion of food waste and animal waste offered significant environmental, energy and cost benefits compared to manure anaerobic digestion only and sending food waste off to a landfill site for disposal.
The BIOGAS 5000 is an easy to useportable biogas analyzer that allows biogas operators to accurately monitor gas in a biogas digester to ensure digestion is running smoothly. It is useful for both agricultural, food and farm waste (large scale and small scale) and can also be used to monitor digestion processes at sewage and wastewater treatment facilities, as well as other applications where biogas needs to be monitored or methane leaks detected
The separate anaerobic digestion of food waste or cattle manure was hardly feasible.
1. Co-digestion produced significant quantities of biogas, with high methane content
2. Addition of cattle manure enhanced the buffer capacity of anaerobic system.
In co-digestion, the C/N ratio contributed to the improving biogas production
Good Luck!,

we are working in wastewater sludge more agricultural refuses or / and food refuses codigestion, in biological methane production BMP evaluation and after continuous anarobic reactors of 7 l or 70 l.

You might find our report interesting. If focuses on food wastes and black water (toilet sewage). And page 53 discusses the potential of using wastes from ruminant organisms to seed these reactors.

According to the hot topics showed in the Last World congress on anaerobic digestión. The future of the techbology is based on closing the clycle: energy and nutrient recovery. Food waste and manure codigestion has been widely study a lot in terms of identification of key parameters for balancing oligoelements and counteract VFA accumulation. Therefore, the technology is turning into full scale application, development of New models different to ADM1, modelling the electron transfer in methanogenesis and nutrient recovery or precipitation, development of New controll system for digester plant, Biogas upgrade and purifitation, corrotion.
This is huge growing field of research go a head. Your PhD contribution will be upgrading Biogas uses and storage
