“…For example, in the sugarcane industry, residues are generated from two different stages: the first stage is from agricultural activities which produce field residues and the second stage is from the industrial stage which produces process residues. The two main residues from agricultural activities are cane tops and dry leaves which are generated from cane cultivation while filter mud, bagasse and ash generated from the juice clarification process, cane squeezing and burning of bagasse, respectively, are the main residues of the industrial stage in the sugarcane industry [23]. In Malaysia, the palm oil industry alone is estimated to generate 80 million tons of solid biomass composed of oil palm empty fruit bunch, frond, mesocarp fiber and trunk and 60 million tons of palm oil mill effluent (POME) per annum [24].…”

“…Compost production from different types of agro-industrial waste improves the soil pH, organic carbon and nitrogen, cation exchange and water holding capacity as well as reducing the potential for erosion and runoff and permanent wilting point in the soil [23]. Lou et al [41] reported that the application of mature composts derived from spent mushroom substrate increased the nitrogen content in the soil from 157.35 mg N kg −1 to 400 mg N kg −1 after 42 days of incubation as compared to the control.…”

Enhancement of Agro-Industrial Waste Composting Process via the Microbial Inoculation: A Brief Review

Composting is an important technology used to treat and convert organic waste into value-added products. Recently, several studies have been done to investigate the effects of microbial supplementation on the composting of agro-industrial waste. According to these studies, microbial inoculation is considered to be one of the suitable methods for enhancing the biotransformation of organic materials during the composting process. This review provides up-to-date research findings on microbial inoculation strategies and their role and functions in enhancing the composting process and the improvement of compost quality. Based on this review, the addition of microorganisms could enhance the composting process such as accelerating the organic matter degradation, mineralization and microbial enzymes activities, and the quality of the end-products such as high germination index. It is important to notice in this strategy that sludge’s microbial consortium is feasible to enhance the composting process in pilot-scale and industrial-scale productions. Besides, it also reduces the cost of compost production. The findings of this review show the various positive impact of microbial inoculation on agro-industrial waste composting which in turn might be useful as a reference for selecting a suitable inoculum based on the type of waste materials.

“…In view of the huge amounts of agricultural waste material (straw, byproducts of food manufacturing a.s.o.) which sum up to 2 billion tons worldwide it should be possible to recycle a distinct percentage in form of composts in order to improve soils and simultaneously store at-mospheric CO2 (Singh et al 2021).…”

Enriching soils with composts and organic waste material will be necessary because high C soils have strong climate change resilience and guarantee stable yields. Annually ≈1 billion tons of agricultural waste is produced which can be brought back to soils after adequate treatment and can relieve atmosphere from CO2. In a field trial municipal solid waste compost (MSW), sphagnum peat (WT), and black peat (HT) were tested. Basic soil parameters pH, C-content and plant nutrients (K, Mg) are significantly increased by MSW. WT and HT were uninfluential. Similar effects are found for microelements Fe, Mn, Zn, and Cu. MSW increased microelements significantly.

Abstract. Shaibu CO, Dinshiya J, Shaibu VE. 2022. Short Communication: Extraction and characterization of pectin from ripe and unripe mango (Mangifera indica) peel. Asian J Nat Prod Biochem 20: 16-20. Pectin is a heteropolysaccharide present in the cell walls of different plants at different concentrations with widespread applications. This work aimed at extracting and characterizing pectin from ripe and unripe mango peel to investigate the effect of ripeness on the yield and quality of mango pectin. To obtain the optimum extraction condition, pectin was extracted at varying temperatures, time and pH using 0.1 N HCl as the extraction solvent. The maximum yield of pectin was found to be 22.67% for ripe mango peel and 21.90% for unripe mango peel. The optimum extraction conditions were found to be 90ºC, 60mins and pH 1.5. The pectin extracted using the optimum extraction conditions was then characterized. The moisture content, ash content, methoxyl content, equivalent weight, anhydrouronic acid and degree of esterification of the ripe mango peel pectin were found to be 8.76±0.08%, 10.12±0.47%, 9.17±0.27%, 883.07±13.85 g, 72.45±0.59 and 72.52±0.09% , respectively. In contrast, those of unripe mango peel pectin were found to be 8.13±0.13%, 9.12±0.34%, 8.83±0.19%, 823.38±14.07 g, and 71.56±0.34%, 70.34±0.38%, respectively. This study showed that ripe mango peel might be more suitable for use as a pectin source. However, pectin extracted from ripe and unripe mango peel could be considered an alternative source of pectin in food processing, pharmaceutical industries, and various places of pectin application.
