“…The fresh waste's initial TOC percentage was 49.36% (Table 1), close to the 43.3% to 46% for vegetables and greens [32] and between the 47.68% to 51.33% for rice straw and paper waste [33]. At the end of pre-composting, the TOC value was 39.95%, therefore the removal percentage was 19.06%, similar to removal efficiencies determined by [34,35]. Other authors report that at the end of the process, they obtained TOC values within the range of 33.8% to 35.7%, with a removal efficiency of 21.93%, similar to the value obtained in this study.…”

Pre-Composting and Vermicomposting of Pineapple (Ananas Comosus) and Vegetable Waste

In the last few years, pineapple (Ananas comosus) has grown to be considered one of the most important fruits worldwide due to its high production and consumption. However, inadequate disposal of the waste it generates, which represents up to 67% of its total weight, can have environmental impacts. Therefore, this study focuses on the degradation of organic waste produced in the industrialized processing of pineapple waste (rinds, crowns and cores), which undergo a process of vermicomposting at a laboratory level. The methodology used included the pre-composting process and vermicomposting through Californian red worms using mixes tested in three different proportions of pineapple waste (PR) and load material (LM) made up of vegetable waste and eggshells. Testing revealed that the pre-composting process for this waste was feasible as a first stage of the degradation process; the characteristics of the pre-composted material allowed a favorable adaptation for both the worms and general degradation. It also showed efficiencies in the removal of organic carbon between 36.40% and 45.78%. Results also showed the total nitrogen content remained between 1.2% and 2.2% and the carbon/nitrogen relation (C/N) had values under 20 as required for high-quality vermicompost.

“…[ 4 – 7 ]), and are widely used as models for basic studies in vermicomposting (e.g. [ 8 , 9 ]), and biomedicine [ 10 – 12 ]. Because the molecular-genetic platforms used in these studies are both sensitive and especially specific, it is crucial that the two eco-physiologically similar commonly used species, Eisenia andrei ( Ea ; ‘red worms’) and E .…”

Lumbricid earthworms Eisenia andrei (Ea) and E. fetida (Ef) are simultaneous hermaphrodites with reciprocal insemination capable of self-fertilization while the existence of hybridization of these two species was still debatable. During the present investigation fertile hybrids of Ea and Ef were detected. Virgin specimens of Ea and Ef were laboratory crossed (Ea+Ef) and their progeny was doubly identified. 1 –identified by species-specific maternally derived haploid mitochondrial DNA sequences of the COI gene being either ‘a’ for worms hatched from Ea ova or ‘f’ for worms hatched from Ef ova. 2 –identified by the diploid maternal/paternal nuclear DNA sequences of 28s rRNA gene being either ‘AA’ for Ea, ‘FF’ for Ef, or AF/FA for their hybrids derived either from the ‘aA’ or ‘fF’ ova, respectively. Among offspring of Ea+Ef pairs in F1 generation there were mainly aAA and fFF earthworms resulted from the facilitated self-fertilization and some aAF hybrids from aA ova but none fFA hybrids from fF ova. In F2 generation resulting from aAF hybrids mated with aAA a new generations of aAA and aAF hybrids were noticed, while aAF hybrids mated with fFF gave fFF and both aAF and fFA hybrids. Hybrids intercrossed together produced plenty of cocoons but no hatchlings independently whether aAF+aAF or aAF+fFA were mated. These results indicated that Ea and Ef species, easy to maintain in laboratory and commonly used as convenient models in biomedicine and ecotoxicology, may also serve in studies on molecular basis of interspecific barriers and mechanisms of introgression and speciation. Hypothetically, their asymmetrical hybridization can be modified by some external factors.

“…The choice of applied technology depends strongly on the characteristics of raw sludge. Some parameters are crucial for the processes of stabilization, for example, pH, organic acid content, and alkalinity limit the Sanitary and environmental aspects of sewage sludge management anaerobic digestion process (Metcalf et al, 2013) while pH, ammonia, and other parameters are important for the composting and vermicomposting processes (Suleiman et al, 2017).

“…Composting as a method of biological decomposition of biowastes in the presence of oxygen contributes powerfully to the recycling and conservation of several macroand micronutrients from sewage sludge in the soil. Its alternative, vermicomposting, is a modern, inexpensive, and eco-friendly biotechnology in which earthworms are employed as natural bioreactors in order to decompose the organic matter (Suleiman et al, 2017). Their metabolic activity and cooperation with microorganisms lead to a 40%-60% reduction of volume, an increase of bioavailability of nutrients to plants, a reduction in the C/N ratio, and a decrease of the availability of some dangerous contaminants such as metals (Rorat et al, 2015).…”
