Composting plants should be operated at a high degradation rate in order to lower their capital and operational costs. Initial C/N ratio is one of the most influential factors on the composting process. This study aimed to determine the impacts of initial C/N ratio on operational composting parameters of two‐phase olive mill pomace with separated dairy manure. Five initial C/N ratios ranging from 29.43 to 43.33 were examined using fifteen 100 L cylindrical reactors. The highest decomposition rate was estimated at 0.02 day−1 with the C/N ratio of 34.49. The maximum relative heat generation was obtained with the C/N ratio of 36.07. The C/N ratio of ≅33 reduced the composting cost of process‐based total airflow supplied per dry matter and organic matter loss. The maximum throughput capacity was obtained when the compost blend had the C/N ratio of ≅37.24. It was concluded that operating the composting of two‐phase olive mill waste, separated dairy manure, and straw with the boundary of the initial C/N ratios between 33 and 37 was recommended.

Composting process parameters such as C/N ratio, moisture content, and temperature are well studied, but limited knowledge exists on energy consumption of the process itself. In this study, co‐composting of rose oil‐processing wastes (ROPW) with caged layer manure and straw was performed to optimize the system in terms of energy use. Intermittent aeration applied to the five compost mixtures with initial C/N ratios of 12.81, 21.37, 24.66, 29.22, and 37.41 was conducted using fifteen identical cylindrical reactors with volume of 60 L. O2 and CO2 concentrations, compost temperature, dry matter loss, organic matter loss, electrical conductivity, and pH were measured. A first‐order kinetic model based on material mass balance was applied to determine kinetic parameters such as decomposition rate and compost equilibrium mass. An equation describing specific energy per initial dry mass of composting as a function of initial C/N ratio was presented and used to optimize initial C/N ratio to maximize composting of ROPW to reach a given level of compost mass ratio. The maximum decomposition, based on dry matter loss, occurred at the initial C/N ratio of 30.18 was 0.032 kg kg−1 day−1. Initial C/N ratio to minimize specific energy use of ROPW composting with caged layer to reach a given level of compost ratio of 0.82 was 29.11. Composting operation can be performed at this initial C/N ratio (29.11) to minimize airflow to keep the power requirement low while still operating the system efficiently. This helps to reduce the energy required for ROPW composting with caged layer to reach a given compost mass ratio. © 2016 American Institute of Chemical Engineers Environ Prog, 36: 129–137, 2017

“…The residual plant materials and the distillation wastewaters are the two main byproducts of oil distillation that are produced as industrial wastes [28]. The rose petals from each farm were combined with water in a weight-to-volume ratio of 1:10 to extract the oil [29]. Following the extraction process, the solid distillation wastes (SDW) from each farm were collected as triplicates.…”

The objective of the current study was to examine the chemical composition and biological functions of the various Taif’s rose (TR) organs and floral solid distillation wastes (SDW). Additionally, it assessed the SDW’s potential use in animal feed and potential health applications. For chemical and biological analyses, the plant stems, leaves, and flowers as well as the SDW of TR were gathered from four farms in the Al-Shafa highland region of Taif, Saudi Arabia. The highest levels of cardiac glycosides, flavonoids, and phenolics were found in the flowers (7.66 mg securiaside g−1, 16.33 mg GAE g−1, and 10.90 mg RUE g−1, respectively), while the highest carbohydrate and alkaloid contents were found in the TR leaves (2.09% and 9.43 mg AE g−1, respectively) with no significant differences from the SDW. Quercetin, apigenin, and rutin flavonoids, as well as isocorydine and boldine alkaloids, were found in larger concentrations in the flowers and floral SDW than in the leaves and stems. The various TR flower extracts were effective against Gram-negative and -positive bacteria but had no effect on fungal strains, but the SDW’s methanol extract was only effective against fungi. The plant stem had the highest N, K, and Mg contents (138, 174, and 96.12 mg kg−1, respectively), while the leaves had the highest P and Ca values (6.58 and 173.93 mg kg−1, respectively). The leaves had the highest contents of total carbohydrates and acid detergent fibre (59.85 and 3.93%, respectively), while the stems had the highest total protein and acid detergent fibre (8.66 and 24.17%, respectively), and the SDW had the highest fats and crude fiber (0.57 and 36.52%, respectively). The highest amounts of digestible crude protein, gross energy, and total dissolved nutrients (TDN) (4.52% and 412.61 Mcal kg−1) were found in the plant stem and flowers, respectively. The results of the current experiment showed that the TDN contents of the various organs and the SDW of TR are suitable for mature dry gestating beef cows. It was determined that, in addition to the SDW’s potential usage as an ingredient in animal feed, various plant parts and TR’s SDW can be utilized for a variety of medical reasons.
