This study focused on what combination of anaerobic digestion (AD) temperature (ambient, mesophilic, and thermophilic) and olive mill waste (OMW) to dairy manure (DM) ratio mixture delivers the desired renewable energy and digestate qualities when using AD as olive mill waste treatment. OMW is widespread in the local environment in the North Sinai region, Egypt, which causes many environmental hazards if left without proper treatment. Three different mixtures consisting of OMW, dairy manure (DM), and inoculum (IN) were incubated under ambient, mesophilic, and thermophilic conditions for 45 days. The results showed that mixture B (2:1:2, OMW:DM:IN) at 55 °C produced more methane than at 35 °C and ambient temperature by 40% and 252%, respectively. Another aim of this study was to investigate the effects of the different concentrations of the digestate taken from each mixture on faba bean growth. The results showed that the maximum fresh weight values of the shoot system were observed at 10% and 15% for mixture B at ambient temperature. The best concentration value for the highest root elongation rate is a 5% addition of digestate mixture A at 55 °C, compared with other treatments.

The current non‐circular and non‐regenerative approaches to farm dairy waste management have spurred a search for alternatives. Anaerobic digestion of the waste to collect biogas and digestate products is an option with significant potential for reducing the farm's environmental footprint and generating additional revenue. Although much research exists on the anaerobic digestion of dairy manure, there is a lack of detailed understanding of the challenges faced with farm dairy effluent (FDE). In addition, most existing studies lack key data, such as the on‐farm process cost. Therefore, the main aim of this review is to highlight these challenges and offer new insights into possible state‐of‐the‐art solutions The conventional methods of FDE disposal are critically compared to anaerobic digestion for economic, environmental, and technical feasibility. The paper also extends into a case study where a preliminary techno‐economic assessment showed that in New Zealand, $2.3 million would be required to set up a farm anaerobic digestion plant with a 900‐cow capacity. This information can aid decision‐making on policies for farm technologies.
