Sosialisasi Pengolahan Limbah Organik Rumah Tangga Melalui Budidaya Magot di Desa Pandeyan, Kecamatan Grogol, Kabupaten Sukoharjo

Organic waste is an environmental problem, especially in the villages of Pandeyan, Grogol, Sukoharjo, so there is a need to solve this problem through direct community activities. One solution is the socialization activity on organic waste processing through magot cultivation in Pandeyan village. With this socialization, it is hoped that the community will gain further understanding regarding magot cultivation as an effort to process household organic waste to make it more useful. The socialization activity was conducted at the Pandeyan village office on August 30, 2023. To measure the success of socializing organic waste processing through magot cultivation, an evaluation was carried out using a questionnaire method distributed to participants. From the questionnaire results, it was found that 88.9% of the total participants understood magot cultivation. Meanwhile, if you look at the potential of organic waste in each household participating in this socialization, it is possible to process it through magot cultivation. However, there is still a need for assistance and further understanding regarding magot cultivation because there is still a stigma that maggots have a maggot-like shape and are not suitable for cultivation.

Potential Impact of Municipal Solid Waste: Case Study of Bahir Dar City, Ethiopia

This study was carried out to determine the potential impact of municipal solid waste in Bahir Dar city. The disposal of municipal solid waste in an open dumpsite in Bahir Dar has an environmental impact in terms of greenhouse gas emissions, eutrophication, and leachate. The quantity of greenhouse gases emitted from the open dumpsite of Bahir Dar city was determined by using IPCC default method. Currently around 148 tons/day waste is generated from Bahir Dar city and from these waste 58% of the waste is disposed into open dump site. From the waste disposal site 46Gg/year of greenhouse gas is emitted. The molecular formula that was determined from organic waste of the city is C24H36O13N. By using this molecular formula of the organic waste, the theoretical oxygen demand becomes 38.75 and then the eutrophication potential of organic waste generated from Bahirdar city was 0.0594 Kg N-equivalent or 59.4g N-equivalent. The average annual leachate resulting from the waste reaches 1,112mm per day. Bahir Dar city should start to implement 3R (Reduction, Reuse and Recycling) solid waste management options in order to reduce potential environmental impacts. For more investigation quantification of the other impacts associated with municipal solid waste is recommended.

The Potency of Avocado Seeds (”Persea Americana” Mill.) as a Source of Antioxidant Tea

The processing of avocado into avocado juice will produce organic waste, namely avocado skin, and seeds. This potential of organic waste from avocado seeds can be exploited by turning them into tea products. This study employed avocado seed as a source of antioxidants which was made into processed products, namely tea. This research was intended to discover the influence of temperature with avocado seeds on antioxidants as well as the quality of resulting tea products and to determine the best conditions for the drying process of avocado seed tea. This investigation was arranged at the Integrated Lab of Politeknik Indonesia Venezuela and the Laboratory of Banda Aceh Industrial Research and Standardization Center. The experimentation adopted a factorial completely randomized design pattern composed of 2 (two) parameters. The first parameter was avocado seed drying temperature comprising 3 (three) degrees, they were S1 (50°C), S2 (60°C), and S3 (70°C). The second parameter represented the drying time of avocado seeds which comprised 3 (three) degrees, they were L1 (2 hours), L2 (2.5 hours), and L3 (3 hours). Analysis carried out in the research was water, ash value, phenolic content, antioxidant, and sensory (colour, taste, and flavour). From the research, it was shown that the drying temperature was influenced by the moisture content, ash content, and antioxidant activity of avocado seed tea, while the drying time and the treatments of those parameters made an impact on total phenol. The best quality avocado seed tea was obtained from a drying temperature of 50°C along with a length of drying of 2 hours.

The potential of organic waste as a substrate for anaerobic digestion in Ukraine: trend definitions

This article is devoted to the analysis and prospects of using different types of organic waste to achieve environmental goals. Due to the unique climate and natural resources, Ukraine has significant potential for biomass, the processing of which should solve urgent problems with the disposal of waste, as well as the production of alternative energy sources and biofertilizers. The preferred substrates for anaerobic digestion in Ukraine, considering the technological feasibility, availability, and volume are animal manure (cattle, pigs), bird droppings, plant residues, industrial sludge, common sludges. After analyzing the statistics for 2015-2019, the groups of dominant wastes were identified, and with the help of the built-in function "TREND," the forecast of the waste potential with an organic component for 2021-2026 was constructed. Examining the obtained indicators for different types of waste, the reasons for the tendency of decrease or increase in their formation in the next five years were revealed. The direction of enhancing the sustainability of bioenergy, achieving environmental goals through the bioprocessing of organic waste associated with the ecological safety of production processes were discussed.

Potential of Sustainable Concept for Handling Organic Waste in Tunisia

Nowadays, Tunisia is seeking to implement cost-efficient and sustainable solutions in relation to the treatment of organic waste which, at up to 65%, makes up the largest proportion of total waste generated in the country. Therefore, an efficient tool for decision makers is needed to provide a clear approach about the potential of organic waste as well as the treatment concept, which can be adapted based on technical requirements and local conditions. Results revealed that there is a high variation in terms of the nature of the collected biowaste, which affects the selection of the adopted bioprocess for each geographical zone of the study area. Three main categories of biowaste are produced along the coastline of Tunisia: food waste (FW) (102.543 t/a); green waste (GW) (1.326.930 t/a); and cattle manure (CM) (1.548.350 t/a). Based on the results of similar projects and laboratory-scale research work, anaerobic and aerobic digestion were examined. Regarding aerobic digestion, the monitoring of several physicochemical parameters ascertained that the co-composting of FW and GW at different ratios (GW: FW = 100:0, 75:25, 50:50, and 25:75) allowed the production of a stable and mature compost. A highly qualified end-product was generated from each trial categorized as a finished compost of class V with reference to German Standards of compost. Regarding the anaerobic process, different feedstock mixtures (FW:CM = 0:1, 1:1, 2:1, and 3:1) were prepared to feed semi-continuous anaerobic reactors. However, a significant improvement in the process development was recorded for digesters including a higher fraction of FW, which produced 0.846 LN/kg VSin as the maximum biogas production. Therefore, biological treatments of food waste and different co-substrates seems to be a suitable technique for Tunisia in terms of waste management, environmental, and energy aspects. However, the evaluation of the efficiency of the proposed biological treatments was also verified by a draw-up of a technical and economic feasibility analysis. Although the cost–benefit estimations proved that the profits from both the compost and biogas plants would be very modest, the feasibility of such sustainable projects should not only be evaluated on an economic basis, but also by taking into account socio-environmental considerations including decreasing environmental threats, providing work opportunities, increasing incomes, stimulating public awareness as well as reducing the operating costs linked to landfilling.

Facilities and problems of processing organic wastes by family-type biogas plants in Ukraine

The potential of organic wastes in Ukraine for biogas production and the prospects of using the family-type biogas plants for this purpose are shown. In the biogas laboratory of the Ukrainian National Forestry University the efficiency of the anaerobic mesophilic digestion of chicken manure of Poltava poultry farm, Kamianets-Podilsky poultry farm and sewage sludge from Lviv wastewater treatment plant (WWTP) was investigated. Different integral indicators of the biogas production and significantly different dynamics of its formation over time were obtained for three investigated substrates. The value of average specific biogas production from the sewage sludge of Lviv WWTP is 0.494 dm3∙(day∙kg FM)–1, which is 5.1 times more comparing the chicken manure of Kamianets-Podilsky poultry farm and 8.0 times more than for the chicken manure of Poltava poultry farm. Strong negative effect of antibiotic treatment of chickens on methane contentin the obtained biogas was established experimentally.

Caringin Central Market is a traditional market in Bandung which is managed by the private party. This market produces approximately 84 tons of waste per day. The waste management system used is the 3P system (Pengumpulan, Pengangkutan, dan Pembuangan) including Collection, Transport, and Disposal of waste. The operational cost for this system is relatively high, which is IDR 55,440,000 per day. Therefore a study to investigate the potential utilization of organic waste from Caringin Central Market as raw material for biogas and compost is necessarily needed to be conducted. The research method used for this study is a field survey to collect primary and secondary data. The methodology is based on the National Standard of Indonesia (SNI 19-3964-1995) for waste sampling to study the waste characteristics and generation. This study is conducted in a temporary disposal site in Caringin Central Market. The results showed that the utilization of organic waste from the Caringin Central Market as raw material could potentially produce 6,272 m3 of biogas and 4.2 tons of mature compost.

СОВРЕМЕННОЕ СОСТОЯНИЕ И ПЕРСПЕКТИВЫ РАЗВИТИЯ БИОГАЗОВОЙ ЭНЕРГЕТИКИ В УЗБЕКИСТАНЕ

Energy is one of the main pillars of the state’s economy, which is currently facing serious problems due to depletion of mineral energy resources and the threatening environment. As a result, presently around the world there is a rapid growth and development of energy-efficient technologies and the use of renewable energy sources (RES), providing an increase in energy resources, as well as environmental and social effects. One of the most relevant and promising areas of renewable energy development is the disposal and processing of organic waste in biogas plants, and this is particularly relevant in agricultural regions. In this regard, this paper considers the state and prospects for the development of bioenergy in agricultural regions of Uzbekistan, where half of the population of the republic lives. The potential of organic waste from livestock and poultry farming of the agricultural sector was determined, and it was revealed that the use of biogas plants for the disposal of manure and litter is clearly a profitable production and requires close attention from rural producers. The introduction of biogas technologies for the bulk of agricultural producers is an urgent task, that will ensure not only a solution to the waste problem, but it will also provide a solution to energy, agricultural, environmental and social problems in rural regions of the republic.

Use of the Energy Potential of Organic Waste during its Incineration at Recycling Facility

To develop recommendations for improving the efficiency of the use of resource potential of organic waste, studies were carried out on the process of their thermal treatment using the example of plant manufactured by company Wellons type 2D6C8.AO. The plant is operated at one of the enterprises of the pulp and paper industry and is designed to generate process steam both by burning primary gas fuel and by using as a fuel mixture different types of organic waste (bark and wood waste, wood chips and sewage sludge). Based on the results obtained, the criteria for estimate the quality of fuel mixture: ash content (not more than 5 %), humidity (not more than 58 %), calorific value (not less than 4000 J/g), homogeneity of the component and fractional composition of the fuel mix (grain size not more than 25–50 mm) were worked out. Taking into account the developed criteria, the optimum composition of fuel mixture was determined (bark and wood waste 70–80 %, pulp and paper sludge 20–30 %, wood chips 4 %). As the main measures to reduce and stabilize the humidity of the fuel used for combustion, the introduction of dry debarking of wood, preliminary mechanical dewatering of the pulp and paper sludge, additional dosing in the main waste stream of waste formed in auxiliary industries (wooden pallets, boxes, paper scrap, etc.) is recommended. The introduction of the developed measures will prevent the disposal of waste in the environment and minimize the impact of the landfills on the geosystems.

Exploring the Potential of Organic Waste as a Source of Methane Gas for Electricity Generation in Nigeria

Open dumps and ill equipped landfills are some of the characteristics of solid waste management in Nigeria. This paper therefore seeks to investigate the viability of anaerobic digestion as part of an integrated waste management strategy for the city of Port Harcourt, Nigeria. In order to achieve this aim, the paper reviews literature on solid waste management in the study area. Alaboratory experiment was also conducted using organic solid wastefrom Port Harcourt. From the findings, it was revealed that anaerobic digestion could play a major role towards the attainment of sustainable solid waste management in Port Harcourt. The small laboratory sample of 10 grams used for the experiment produced about 0.796 litres of methane gas, means that 1 tonne of organic waste in Port Harcourt will generate about 79600 litres of methane gas with energy equivalent of about 1592000_kj. The paper concluded that in a city like Port Harcourt where several tonnes of solid wastes are produced every day, a substantial amount of methane gas could be recovered for electricity generation. It was therefore recommended that anaerobic digestion should be used in order to boost the electricity capacity of the city whilst also improving the quality of life of the people.

Development of optimum substrate compositions in the methane fermentation process

AbstractThe aim of the study was to assess the potential of organic wastes from the agriculture and food industry as co-substrate for biogas production, on the basis of physical and chemical parameters analysis and biogas yield in the process of methane fermentation. The experimental material consisted of carrot pomace, kale by-products and maize silage. Methane fermentation was conducted in bioreactors equipped with an automatic control and measurement system. The study indicated correct physicochemical properties in terms of high content of dry organic matter and also correct C/N ratio. That was reflected in high biogas yields which amounted to, respectively, 558 N dm3kg−1VS−1for carrot pomace and kale by-products, and 526 N dm3kg−1VS−1for maize silage. The study showed that the intensity of biogas production was varied and depended on the composition of fermented mixtures. Methane fermentation of organic waste mixtures significantly increased the amount of biogas efficiency compared to the fermentation of individual substrates. The successful run of the experiment indicates that a mixture composed of carrot pomace and kale by-products is a good substrate for the production of biogas.

Potential of Organic Wastes as Liming Materials in Low Input Rainfed Agricultural System

A field experiment was conducted on an acid soil in a humid tropical Island of Andaman, India to explore the feasibility of using locally available organic wastes as liming materials after suitable composting. The organics such as coconut husk compost, poultry manure, vermicompost and gliricidia were incorporated at the rate of 20 Mg ha -1 and the amendment effect was compared with lime applied at the rate of 4 Mg ha -1 . Soil application of composted organic wastes significantly increased the soil pH. The exchangeable Al 3+ showed significant reduction in organic amended soils and completely disappeared in poultry manure and lime treated soils. Significant differences were observed in root volume by application of N rich organic materials compared to control (11.7 mm 3 ) and lime (23.3 mm 3 ) application which helped in increasing volume of soil foraged by maize roots. Poultry manure (3.79 t ha -1 ) and vermicompost (3.73 t ha -1 ) application recorded on par maize grain yield but significantly higher than the control (1.93 t ha -1 ). The results showed the potential of poultry manure and coconut husk composted with either poultry manure or gliricidia as alternate liming material for low input agricultural system prevailing in humid tropical Islands.
