“…It is worth mentioning that TOC values can vary according to the parts integrated into the waste to be studied due to their physicochemical characteristics [43,48]. The final TOC for the OP waste was 41.96 ± 0.69%, which was similar to the 38.1% reported for the precomposting of vegetables, fruits, green waste and tea leaves [49]. The carbon loss was the result of waste degradation by the action of microorganisms and the elimination of precomposted material as CO 2 and CH 4 [45,50].…”

The industrialization process of oranges generates waste, which is inadequately disposed of; this produces adverse effects on the environment. Among the alternatives for valorization is the vermicomposting process, which consists of the degradation of organic waste through the action of earthworms and microorganisms. Therefore, this research aimed to study this process using orange peel (OP) waste at the laboratory level. For this purpose, it was necessary to determine the degradation conditions through the monitoring of physicochemical parameters (temperature, pH, humidity, organic matter (OM), total organic carbon (TOC), total nitrogen (TN) and the carbon/nitrogen (C/N) ratio). To balance the substrate’s nutrients, load material (LM) that included vegetable waste and eggshells was added to three different mixtures: M1 (50% OP + 50% LM), M2 (40% OP + 60% LM) and M3 (60% OP + 40% LM). To condition the substrate for earthworm (Eisenia fetida) activity, a previous precomposting process was performed. The results showed that all the mixtures fulfilled the requirements for a quality and mature vermicompost; however, the highest concentrations for TN were in the mixtures M1 and M2. The total time required for degradation of the OP waste was 13 weeks.

“…In parallel, the seedlings height, the stems diameters and the leaves number of all the experimented seeds were more important in the soil amended by 25% of the FWC (B0) compared to the soil used alone (A0), as well as the substrate (soil 75% + 25% FWC) (B). In contrast, the food waste compost prepared by Voběrková et al [2] and and Kucbel et al [12] showed a total phytotoxic on the experimented plants. On the other hand, when soil amended by 25% of compost was irrigated with fermented compost extract (B), the seedlings were shorter and with a reduced leaves number compared to all the other growth conditions.…”

“…Many treatment solutions of food waste were reported, such as animal feeding [9], anaerobic/aerobic digestion [10], composting [2] [11] [12], pyrolysis [13], gasification, incineration and landfill disposal [14]. The choice of the technology to be applied depends on criteria in relation with the waste typology as well as the available means.…”

“…The temperature and pH were as indicators of the progress of the process and checked the effectiveness of the device, which gave satisfactory results under verification of the entry of compatible C/N ratio, which gave good results in terms of space-saving and prove the possibility of accelerating production by focusing on providing the best conditions for the product and closest to the standards. (Kucbel et al, 2019) conducted study on automatic composter, the composting process was controlled by the composter, composting took place at NatureMill for about seven days. The composter operates during the whole period of composting at the temperature of 55-65 °C (input 1 kg/week).…”

This study aims to manufacture an integrated automatic control unit for the production of organic fertilizer in all steps of production for the fermentation period, by adjusting parameters throughout the process. There are 5 main components, namely: the frame is carrying the cylindrical body-power transmission system-water supply system-ventilation system-control system connected to sensors. The first mixture was made C1 and consists of cattle dung, shredded paper and field residues in proportions of 5: 1: 2.5 and the second mixture C2 was assembled from field residues, sugar cane residues and rabbit dung, the mixtures were made by 1: 0.5: 1.8. These percentages are determined according to the nitrogen carbon ratios of each waste type, which must be adjusted in aggregate to an appropriate entry ratio of 1:30. The variables studied are the speed of the stirring system with four levels (17, 22, 27 and 32 rpm), 3 levels of angles (45, 50 and 55 degrees) as well as three levels of processing time (600, 1200 and 1800 sec). To verify the efficiency of the mixing and mixing were identified 8 points and measure the moisture homogeneity in these points after stirring and add the amount of water initially fit the pile. It was concluded that better moisture distribution resulted from a 50-degree angle with a speed of 22 rpm and a 1200 sec processing time are the best parameters, That give a mixing efficiency.
