Streszczenie:
Vermicomposting is a method of composting by using earthworms, in this process earthworms eat biodegradable wastes (Such as vegetables and fruits peels), and they break down these natural materials into organic fertilizer. Vermicompost is generally used for organic farming and also maintains the health of the soil. The amount of Nitrogen is more as compared to Phosphorus and Potash in vermicompost. Vermicompost doesn’t harmful to the soil and also helps in increasing the nutrient content of the soil. The life of earthworms is 4 - 8 years depending upon the species. The nutrients contents like Nitrogen, Phosphorus, Potash, Calcium, Magnesium, Iron, Manganese, and Zinc are found in vermicompost. Endozoic earthworms are found in a deep layer of soil and they eat 90 % soil and 10 % organic matter. Epizoic earthworms are found on the surface ofthe soil and they eat 10 % soil and 90 % organic matter. Epizoic earthworms are famous for vermicomposting because they produce more vermicompost as compared to Endozoic earthworms. The weight of earthworms is between 0.5 to 0.6 g. one kg earthworm produces 0.8-7 kg vermicompost per day.

A recent report in this journal from these authors, which shows that vermicomposting transforms a toxic weed such as lantana into a benign organic fertilizer, can be of practical utility only if processes can be developed for rapid, inexpensive, and sustainable vermicomposting of these weeds. This paper describes attempts leading to such a process for the vermicomposting of toxic and allelopathic weeds lantana (Lantana camara), parthenium (Parthenium hysterophorus), and ipomoea (Ipomoea carnea). For it, the ‘high-rate vermicomposting’ concept was employed due to which the weeds could be used for vermicomposting directly in each case without the need for pre-composting or any other form of pretreatment. The manure worm Eisenia fetida, which had been cultured on cowdung as feed and habitat, was slow to adapt to the weed-feed but survived and then began to thrive, in all the three weeds, enabling the weeds’ sustained and efficient vermicomposting throughout the 16 month’s uninterrupted operation of the vermireactors. In all cases the extent of vermicast production per unit time showed a rising trend, indicating that the rate of vermicomposting was set to rise further with time. The vermicomposting was found to accompany a 50 ± 10% loss of organic carbon of each weed with a 50 ± 10% increase in the concentration of total nitrogen as also the weed’s additional mineralization. The combined effect was a significant lowering of the carbon-nitrogen ratio, and enrichment of all major, medium, and trace nutrients in the vermicomposts relative to their parent substrates. The findings establish that sustained, direct, and rapid transformation to organic fertilizers of even toxic and allelopathic weeds can be accomplished with the high-rate vermicomposting paradigm.

The aim of this study was to evaluate the carbon dioxide (CO2) and methane (CH4) emissions during the composting and vermicomposting of sewage sludge under the effect of different proportions of straw pellets. Four treatments, including a control with three replicates, were designed to mix the initial sewage sludge with varying rates of pelletized wheat straw (0, 25%, 50%, and 75% (w/w)). Over a 60-day period, vermicomposting with Eisenia andrei treatments and composting were carried out. The results indicated that both composting and vermicomposting produce a significant (p < 0.001) amount of CO2 and CH4 emissions from all treatments. Vermicomposting significantly reduced CH4 emissions by 18%, 34%, and 38% and increased CO2 emissions by 75%, 64%, and 89% for the treatments containing 25%, 50%, and 75% straw pellets, respectively, compared to composting. However, CO2 emissions decreased and CH4 emissions increased during composting compared to vermicomposting. As a result of this finding, both composting and vermicomposting processes are recommended as an additive of pelletized wheat straw, depending on the target gas to be reduced.

Owing to rapid population growth, sewage sludge poses a serious environmental threat across the world. Composting and vermicomposting are biological technologies commonly used to stabilize sewage sludge. The objective of this study was to assess the carbon dioxide (CO2) and methane (CH4) emissions from sewage sludge composting and vermicomposting under the influence of different proportions of straw pellets. Four treatments were designed, by mixing the initial sewage sludge with varying ratio of pelletized wheat straw (0, 25%, 50%, and 75% (w/w)). The experiment was conducted for 60 days, and Eisenia andrei was used for vermicomposting. The results revealed that the mixing ratio influenced CO2 (F = 36.1, p = 0.000) and CH4 (F= 73.9, p = 0.000) emissions during composting and CO2 (F= 13.8, p = 0.000) and CH4 (F= 4.5, p= 0.004) vermicomposting. Vermicomposting significantly reduced CH4 emissions by 18–38%, while increasing CO2 emissions by 64–89%. The mixing agent (pelletized wheat straw) decreased CO2 emission by 60–70% and CH4 emission by 30–80% compared to control (0%). The mass balance indicated that 5.5–10.4% of carbon was loss during composting, while methane release accounted for 0.34–1.69%, and CO2 release accounted for 2.3–8.65%. However, vermicomposting lost 8.98–13.7% of its carbon, with a methane release of 0.1–0.6% and CO2 release of 5.0–11.6% of carbon. The carbon loss was 3.3–3.5% more under vermicomposting than composting. This study demonstrated that depending on the target gas to be reduced, composting and vermicomposting, as well as a mixing agent (pelletized wheat straw), could be an option for reducing greenhouse gas emissions (i.e. CH4, CO2).

India faces a significant challenge with the escalating production of industrial sewage sludge, which contains hazardous heavy metals and toxins, posing a serious environmental threat. Managing the disposal of such waste is increasingly difficult due to its resistance to degradation. This research explores the potential of vermicomposting as a sustainable solution for mitigating heavy metal contamination in sewage sludge. Vermicomposting harnesses earthworms to accelerate organic matter decomposition and immobilize heavy metals. The study investigates various vermicomposting parameters, such as worm species, moisture levels, pH, and NPK to optimize heavy metal removal. Furthermore, it assesses the quality of the resulting vermicompost, focusing on heavy metal concentrations and potential agricultural applications. The findings indicate that vermicomposting holds promise as an eco-friendly method for addressing heavy metal pollution in sewage sludge, offering opportunities for sustainable waste management and soil enhancement.

Vermicomposting is the process of organic waste degradation through interactions between earthworms and microbes. A variety of organic wastes can be vermicomposted, producing a nutrient-rich final product that can be used as a soil biofertilizer. Giving the prolific invasive nature of the Australian silver wattle Acacia dealbata Link in Europe, it is important to find alternatives for its sustainable use. However, optimization of vermicomposting needs further comprehension of the fundamental microbial processes. Here, we characterized bacterial succession during the vermicomposting of silver wattle during 56 days using the earthworm species Eisenia andrei. We observed significant differences in α- and β-diversity between fresh silver wattle (day 0) and days 14 and 28, while the bacterial community seemed more stable between days 28 and 56. Accordingly, during the first 28 days, a higher number of taxa experienced significant changes in relative abundance. A microbiome core composed of 10 amplicon sequence variants was identified during the vermicomposting of silver wattle (days 14 to 56). Finally, predicted functional profiles of genes involved in cellulose metabolism, nitrification, and salicylic acid also changed significantly during vermicomposting. This study, hence, provides detailed insights of the bacterial succession occurring during vermicomposting of the silver wattle and the characteristics of its final product as a sustainable plant biofertilizer.

Ruminants are important sources of meat and milk. Their production is associated with manure excretion. Estimates of over 3,900,000 million metric tonnes of manure are produced daily from ruminants worldwide. Storage and spread of this waste on land pose health risks and environmental problems. Efficient and sustainable way of handling ruminant manure is required. Composting and vermicomposting are considered two of the best techniques for solid biomass waste management. This paper presents vermicomposting as an effective tool for ruminant manure management. Vermicomposting is a mesophilic biooxidation and stabilisation process of organic materials that involves the joint action of earthworm and microorganism. Compared with composting, vermicomposting has higher rate of stabilisation and it is greatly modifying its physical and biochemical properties, with low C : N ratio and homogenous end product. It is also costeffective and ecofriendly waste management. Due to its innate biological, biochemical and physicochemical properties, vermicomposting can be used to promote sustainable ruminant manure management. Vermicomposts are excellent sources of biofertiliser and their addition improves the physiochemical and biological properties of agricultural soils. In addition, earthworms from the vermicomposting can be used as source of protein to fishes and monogastric animals. Vermicompost can also be used as raw materials for bioindustries.

Increasing legislative and economic pressure to find more sustainable methods of organic waste management has fuelled innovation in biological treatment technology. By-products of paper manufacturing industries provide a large source of organic waste, which is known to have a high environmental impact. This waste paper sludge has been shown to be amenable to biological treatment. Recent research has confirmed that windrow-composting and vermicomposting techniques have potential to treat these wastes and share many economic and environmental benefits. Many authors have suggested that sludge specific composting methods need to be developed and this research aims to provide fundamental data in this respect. The treatment of specific waste paper sludges was investigated through small and larges calee xperimentsw ith the aim of optimising thesep rocessesw ith minimal intervention. Identical samples of a selected waste paper sludge feedstock were used in large scale investigations into the application of each composting technique, and the performance of each process and resulting products was evaluated. Windrow composting and vermicomposting were found to stabilise and enhance waste paper sludge in very different ways, producing unique products. In terms of processing, windrow composting resulted in more rapid rates of stabilisation and although the performance of the vermicomposting process was less effective in these respects, it afforded additional benefits as a treatment of waste paper sludge. Both processes were found to stabilise and enhance waste paper sludge but the selection of one system or the other will depend largely on the objectives of the project and the criteria required of the finished product.

Aquaculture, the cultured production of fish, is growing at a rapid pace worldwide. The industry is generating approximately 140,000 cubic meter wastewater per year. For this industry to flourish, viable methods for treating the resulting waste stream must be identified. The various methods were tried by many researchers like sand filtration method, recirculating aquaculture system, intermittent filtration methods. The most of the industries use sand filtration methods for treating aquaculture wastewater and the problems associated: the reduction in hydraulic conductivity, accumulation of solid due to which anaerobic conditions developed. This study investigated possible treatment technologies for wastewater and sludge produced from Blue Ridge Aquaculture (BRA), an indoor, recirculating aquaculture facility where tilapias (Oreochromis) are raised. Research focused on the use of vermicomposting in conjunction with sand bed filtration to filter aquaculture waste and treat the resulting solids. Two experiments were conducted: a feedstock acceptability test and a filter bed test.

The feedstock acceptability test evaluated the suitability of the fish sludge (mixed with cardboard) as a feedstock for the worms involved in the vermicomposting process. The results showed that as the percentage of fish sludge in the feed increased from 0 to 50%, there was a corresponding increase in the growth rate of E.fetida biomass.

The filter bed test appraised the feasibility and effectiveness of incorporating vermicomposting in sand filter beds to directly treat aquaculture wastewater. Popular in early wastewater treatment systems, sand filtration has seen a resurgence in recent years. To test the potential for even more effective filtration, sixteen sand filter beds were established--twelve that included worms and four that did not. Wastewater (1.5 % total solids) from BRA was applied to the sand beds at loading rates of 400 to 1000 grams of volatile solids/m2/week. Filter beds containing worms exhibited no ponding over the 70-day experimental period. However, all units without worms failed (exhibited ponding) by the 24th day of operation.

Removal efficiencies obtained from the filter bed study for total solids (TS), volatile solids (VS), total suspended solids (TSS), chemical oxygen demand (COD), total phosphorus (TP), sulfate, chlorides, and ammonia-N were greater in filter beds with worms than beds without worms. The worms were crucial to maintaining porosity in the filter beds, hence keeping the filters functioning over time. Worm filter beds removed approximately 100% of the TS, VS, TSS and Ammonia-N, 90% of the TP, 50% of the chlorides, 80% of the sulfate and 70% of the COD. Maximum hydraulic conductivity of 35 cm/day was achieved at the maximum application rate. All the worm filter beds therefore had greater hydraulic conductivity than filter beds without worms. The potential impact is to treat the wastewater effectively, to increase the flow of water, and may be to maintain the aerobic conditions on the worm filterbeds.

Although being the third largest city in South Africa, the outskirts of Durban are scarcely populated. Due to economic limitations, the drainage and fresh water pipes from the city are not extended to the outskirts. One of the most important issues concerning human health is that of sanitation and waste management. Lack of sanitation leads to the spreading of pathogens and often results in outbreaks of infectious diseases, such as cholera; one outbreak motivated eThekwini Municipality to install 100,000 urine-diverting toilets in rural areas of Durban. The use of UD toilets can be improved by the use of vermicomposting. Vermicomposting uses earthworms to facilitate degradation of organic material. The aim for this project was to establish whether vermicomposting could improve the function of dry toilet systems, mainly by reducing the volume of the solid fraction. Three toilets were chosen as testing sites. Vermicomposts were created in plastic boxes by adding different types of compost materials, so-called bedding materials, and worms. Two types of bedding material were used, vegetable compost and local topsoil were compared to potting soil and fully digested sludge mixed with soil. Once the vermicomposts had been installed in the toilets, experiments were conducted to determine the performance of the composts. Samples were taken in the field and analysed in the lab. The number of worms and cocoons were counted and the pH, temperature and total and volatile solids were measured and calculated. Solvita® tests were made to determine the state of the composts. In the laboratory test it appeared that the bedding material consisting of potting soil and fully digested sludge was more suitable for vermicomposting; however, no difference could be found in the field. The worms seemed to survive well in the composts. The pH levels were similar to that of the initial pH, which could suggest that the pH stayed relatively stable in the compost. The temperature in the compost stayed close to that of the outside air temperature. The composts could have had been too dry for the worms, but there was a lot of organic matter present. The composts were well matured or under ideal curing. Because of the short time period and the insufficient number of vermicomposts tested, no definite conclusions could be made. However, indications were seen during the project that there was potential for functioning vermicomposting in UD toilets in South Africa and that it would be of great interest to continue the studies further.

European and National legislations in the UK have created a tremendous pressure on the waste management industry for a major expansion of the composting industry over recent years. Also, with the greater awareness of the health and environmental safety within the community, compost producers are forced to provide an authenticated form of quality compost to the consumers. The work presented in this thesis focuses on quality enhancement of mature green-waste derived compost using vermicomposting and air separation techniques. A vermicomposting trial was conducted for a period of 18 weeks by utilising re-hydrated mature green-waste compost produced at Carmarthenshire Environmental Resource Trust (CERT) composting facility as a feedstock. It was found that a minimum average compost mass reduction of 16% was observed by using an average mass throughput of 32.6 kg m 2 week"1. The greatest reduction in volatile solids was observed only during the initial stages of the trial. However, no significant reduction was noted towards the end of the vermicomposting process, when worm mass had reduced to approximately 1.3 kg/m . Replicated growth trials on coriander and tomato were conducted using two commercially available multipurpose composts and five waste-derived composts. It was found that commercial composts showed better plant growth when compared to waste-derived composts. This was followed by another set of growth trials undertaken with lettuce, using pure worm casts (VC), green waste compost (FS) and mixtures of the two Le. 50/50 and 20/80 (VC:FS, v/v) mix. Results showed that plant biomass production was optimal with 20/80 (v/v) mix, whilst VC and FS yielded poor plant growth. In general, the vermicomposting process did not result in an increased availability of nutrients or potentially toxic elements, the only exception being Zn. Characterisation studies were also conducted on unscreened mature compost samples to identify the physical contaminants followed by laboratory and commercial scale air separation trials. Of the coarser fraction from Bryn Pica compost, 1% of plastic film was found. The laboratory air separation trial showed that at the minimum average air velocity of 4.24 m/s, 100% plastic film was removed along with 73% of <10 mm CERT compost During the commercial scale trial, it was found that following screening, the <25 mm fraction would meet the physical contaminant limits of the BSI PAS-100:2005 standard. The 'Komptech Hurrikan' removed 91% of the light materials from the compost oversize (>25 mm). The air jig trial showed promising results and that, in less than 2 minutes, various sizes of stones were separated from the compost stone mix sample.

Rural organic waste is becoming a problem in developing countries due to lack of financial and technological support comparing with situation in urban area. A rural organic waste treatment system was designed utilizing vermicomposting technology to treat organic waste generated in rural area. ROWATS is a theoretical facility to treat rural organic wastes in Shandong Peninsula, China where cow dung and domestic organic waste are disposed freely. Theoretical demonstration shows that ROWATS can treat 1,200 kg of organic wastes daily and produce around 20 tons of vermicast and 800 kg of earthworm body and larvae every month. Products of ROWATS can be used as soil fertilizer, fish bait, and biopharmaceuticals and so on. Sufficient financial support is the most important factor for ROWATS in rural area. Cost-Benefit Analysis and Net Present Value Calculation were made to assess the feasibility of ROWATS. Results showed that ROWATS is a profitable project in terms of 2 years and 5 years. Sensitivity Analysis is also applied to evaluate the impact of different factors variation on ROWATS, of which result shows price and productivity variation of products can affect the profit of ROWATS more significantly comparing with cost changes. Hence, operator should keep products production stable. ROWATS can also improve the environmental and hygienic impacts through reduction of leakages, odor and bacteria and virus infection from flies, mosquitoes and other poisonous species.
