“…This could be explained by the absence of mineral elements from OPEFB in this medium, which is important for the growth of S. platensis. These results are supported by those obtained by Gnimassoun, Ettien, and Masse (2020) working on the characterisation of the physicochemical properties of compost from a mixture of OPEFB and poultry droppings revealed that OPEFB is very rich in important nutrients for plant growth. On the other hand, the culture medium formulated with 10 g L -1 of OPEFB has a low optical density and biomass, which is explained by the fact that at too high concentrations, the medium becomes rather toxic for the crop.…”

S. platensis is a cyanobacterium known for its richness in protein and bioactive compounds, with very captivating therapeutic and nutritional properties. In Cameroon, the medium commonly used for the cultivation of S. platensis is Jourdan's medium which is expensive and less available. Thus, it is necessary to find an alternative medium that is more efficient, less expensive and more available. Nutrients present in agro-industrial by-products can be used to enhance the production of biomass and photosynthetic pigments of S. platensis. Therefore, this study was conducted to evaluate the growth and Photosynthetic pigments productivity of S. platensis on the Oil Palm Empty Fruit Bunch (OPEFB) medium. The culture medium was formulated by distilling different concentrations (0; 2; 4; 6; 8 and 10 g L-1) of ash from previously dried and incinerated OPEFB medium in distilled water. The highest optical density (1.01 ± 0.09), dry biomass (1.35 ± 0.10 g L-1) and productivity (0.032 g L-1d-1) were recorded on the medium formulated with 8 g L-1 of the OPEFB compared to the standard (Jourdan medium). The same medium showed the highest content of chlorophyll a (4.96 ± 0.31 mg L-1), chlorophyll b (2.21 ± 0.16 mg L-1) and carotenoids (1.43 ± 0.01 mg L-1). However, the protein (156.1 ± 0.70 mg L-1) and sugar (4.50 ± 0.43 mg L-1) contents recorded on the standard medium were significantly high (P < 0.05). These results suggest that the OPEFB medium is a potential medium for S. platensis culture that can replace the expensive and less accessible Jourdan medium.

“…This decrease increases with the amount of manure added in the different treatments, whatever the element, from T0 to T3. The percentage loss was 88.55 to 95.39%, 73.31 to 83% and 81.48 to 87.22% for Cr, Pb and Zn respectively [Gnimassoun et al, 2020]. Indeed, according to Pakou et al (2009), composting reduces the availability of metals present in organic waste.…”

It is important to address metabolic and heavy metal issues in organic waste through sustainable development, circular economy principles and effective solid waste management, particularly focusing on composting as a crucial approach recognized in Morocco's Green Generation Plan to reduce waste sent to landfills and mitigate greenhouse effects and gas emissions to fight against environmental pollution. This study aims to elevate the significance of organic waste in agriculture by employing composting technics, thereby mitigating its heavy metal content and safeguarding soil and farmland against various forms of contamination. This approach aligns seamlessly with the principles of sustainable development and the circular economy, advocating for responsible waste management and the augmentation of natural resource value. The findings of the study indicated a decrease in heavy metal levels across all composts, with a minimum values at the end of the composting in Gr compost recorded in all heavy metals analyzed (Pb -0.1125 mg•kg -1 , Cd -0.08 mg•kg -1 , Cr -2.22 mg•kg -1 , Zn -10.88 mg•kg -1 , Mn -28.85 mg•kg -1 , Cu -8.30 mg•kg -1 , Fe -545.18 mg•kg -1 and Ni -1 mg•kg -1 ). The findings from the assessment of heavy metal levels in the examined compost samples demonstrate their adherence to regulatory standards. Consequently, these composts can be confidently employed as organic soil enhancers, contributing to the enrichment of agricultural soils and fostering plant growth, all while avoiding the potential hazard of undue metal contamination. This study comes to confirm and consolidate previous works findings regarding the valorization of organic solid waste through composting and to minimize their major environmental risks by reducing trace metal elements through this biological process.

“…Based on Figure 8, T4 recorded the highest value of mean number of fruits per plant while T1, T2 and T3 has the lowest. In a previous study, the use of EFB compost enhanced the yield of soybean by 50% [21]. Furthermore, EFB compost is abundant in nutritional components, which led to the subject of using compost as a fertiliser for the purpose of increasing soil fertility [22].…”

Chili Kulai (Capsicum annuum L) is a typical and popular chili that utilized by Malaysians as a spice in their daily food, emphasize its economic value. The objectives of this study were to evaluate the effect of empty fruit bunch (EFB) compost and Trichoderma biofertilizer on the growth and yield performance of chili production, as well as to determine physicochemical properties of soil and to evaluate N, P, K content of chili plant tissue. The experimental design used was Randomized Completely Block Design (RCBD) with four treatments replicated four (4) times with four plants giving a total of 64 experimental units. The treatments involved were: T1 (Control), T2 (100% EFB compost), T3 (100% Trichoderma biofertilizer) and T4 (50% EFB compost + 50% Trichoderma biofertilizer). The results revealed, there was a significant difference (p<0.05) for growth and yield performance of chili production. As for the nutrient content (%) in both soil and plant, T4 showed the highest NPK content with N (1.98%), P (0.76%) and K (0.69%). In conclusion, this study proved that the use of organic based EFB compost enriched with Trichoderma biofertilizer has increased the yield of chili plant, thus reducing the use of chemical fertilizer.
