On the (In)visibility of Practices: Opportunities for the Promotion of Household Waste-Segregation in Western Switzerland

Organic waste is both a refuse and a resource. Focusing on household waste in a city in Western Switzerland, this study examines the practices of waste segregation in relation to the city’s (organic) waste management system. Based on qualitative research with diverse households and experts in waste management, we use social practice theory to discuss the meanings and materiality of household organic waste segregation. We show how more or less visible meanings, tied up with material arrangements, can be either enablers or deterrents for such forms of waste management. The article argues that certain aspects of the waste system could be rendered more visible, such as the proper labelling of collection bins, while less visibility could be given to certain meanings around waste segregation, such as the financial cost of not sorting. We also discuss how organic waste sorting, as a practice, contests the dominant understandings of change based on technological efficiency, economic benefits, and individual changes. More collective forms of change are needed, working at the level of social contexts and materiality, to further support organic waste sorting.

Household Waste Management Strategy in Upper Middle Housing

The growing volume of waste poses a significant challenge, with implications for environmental contamination, health, and aesthetics. While participatory waste management practices have been adopted in some areas, others resort to dumping on vacant land, leading to potential long-term repercussions. The focus on waste source management, particularly within households, becomes imperative. A descriptive study was conducted in the Sukabumi Sub-district, with the most residences. Targeting households with heads of families as respondents, the research encompassed a sample of 120 housing units selected through systematic random sampling. Instruments developed by the researcher were employed for data collection. Analysis was anchored on a univariate approach and the SWOT (Strengths, Weaknesses, Opportunities, Threats) method. The community's education, knowledge, and occupation profiles were categorized as 'good'. Despite this, a gap in waste governance was identified. Community knowledge about waste management emerged as a strength, while the unrealized potential of converting organic household waste into compost was recognized as an opportunity. To address waste management effectively, it is recommended to prioritize community strengths and harness available opportunities, like independent composting through suitable technology for limited land areas. Emphasizing household waste reduction through the 3R+P model, tailored for upper-middle-class housing, and bolstering community waste management awareness through continuous campaigns is essential.

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.

Emissions associated with the management of household organic waste, from collection to recovery and disposal: A bottom-up approach for Sydney and surrounding areas, Australia

Recent advances in waste management policies and initiatives world-wide have placed greater focus on the potential greenhouse gas emissions-avoidance that can be achieved via sustainable waste management practices. In New South Wales, Australia, household organic waste has been identified as a problematic stream that through better management, could lead to better environmental outcomes and reduced emissions. However, emissions associated with waste management are poorly characterised in Australia, obscuring decision making around optimal pathways that can maximise landfill diversion and minimise emissions. This study addresses this data limitation by estimating and analysing the emissions associated with household organic waste management. The approach applied route optimisation to estimate emissions from points of collection (weekly and fortnightly) to recovery at composting facilities and disposal at landfills, as well as mass balance modelling to estimate direct and indirect emissions associated with windrow composting and mechanical biological treatment. Landfill gas modelling was also used to estimate lifetime emissions from disposal, as well as potential avoided emissions through recovery. Results for the Greater Sydney and surrounding area show total gross greenhouse gas emissions of approximately 390,100 tCO2-e, and balanced by approximately 145,600 tCO2-e of emissions avoidance through landfill diversion. The average net emissions intensity of jurisdictions in the study area was approximately 133 kgCO2-e/t of waste diverted; or 423 kgCO2-e/t of waste managed. Emissions intensity was highest for the mixed waste collection stream, where diversion pathways are limited; and lowest where separate food collection and mechanical biological treatment was employed. Findings indicate that greater separation of food waste from the mixed stream to dedicated food waste collection will result in the greatest improvements in both emissions intensity and landfill diversion.

Mortality, Development and Nutrient Content of Black Soldier Fly Larvae (Hermetia illucens L.) Maintained on Different Types of Household Organic Waste

Black Soldier Fly (BSF) has been well studied for many purposes including its utilization as fish feed and decomposer of organic waste. At the grassroots level, this species is used for alleviating the household waste problem, however, long-term mass rearing becomes challenging due to the high mortality and declining size of larvae, and its nutritional content as an alternative to fish feed becomes a question. The objective of this study is to evaluate the effects of different types of household organic waste on larval development, mortality rate, and nutrient content when larvae enter pre pupa stage. Seven days old larvae were maintained with five different types of fresh household organic waste, vegetable waste, animal waste, and mixed waste with three different combinations between vegetable and animal waste with proportions 1:1, 1:3, and 3:1. There are five units for each treatment with each unit containing 50 larvae. Larval morphometry and volumetry, Waste Reduction Index/WRI, Survival Rate/SR, and proximate analysis were observed. Types of Organic household waste significantly affect the mortality, development, and nutrient content of BSF larvae. BSF larvae maintained with a combination of vegetable waste and animal waste with a ratio of 3:1 have a better quality in terms of mortality, development, and nutrient content.

Effect of Household Solid Waste Compost on Growth and Yield of Tomato (Lycopersicum esculentum L.) in Agroforestry System

Improvement of environment and soil fertility through utilization of compost produced from household organic solid waste is effective and agroforestry system is an effective technology to increase the production per unit of area. For this reason, a research was conducted to evaluate the performance of household solid waste compost on growth and yield performance of tomato in agroforestry system at the experimental field of Sher-e-Bangla Agricultural University, Dhaka during the period from November 2020 to June 2021. The experiment was conducted with five treatments viz. T1, T2, T3, T4 and T5 as recommended dose of fertilizer, 10 ton/ha, 15 ton/ha, 20 ton/ha and 25 ton/ha household solid waste compost, respectively which were arranged by Randomized Completely Block Design (RCBD) with three replications. Moringa tree was used as tree species and BARI Tomato-2 was planted under moringa tree. The household solid waste compost showed effects on growth and yield performance of tomato compared to recommended dose. T3, T4 and T5 showed significant effects on 80% flowering (DAT), fresh weight per plant, dry weight per plant, fruit number per plant, weight of individual fruit, fruit weight per plant, fruit yield per hectare compared T1 (RDF) but T2 (10 ton/ha) decreased significantly compared to RDF (T1). Among those three treatments (T3, T4 and T5), T5 showed significant effects on fresh and dry weight of tomato plants, fruit number per plant, weight per fruit, total fruit weight per plant and fruit yield per hectare than T3 and T4. So, T5 (25 ton/ha) showed optimum yield of tomato in agroforestry system compared to recommended dose and other doses.

Effects of Eudrilus eugeniae Worms and Cow Manure on the Vermicompost Process of Household Organic Waste

High population growth in developing countries also increases the amount of waste. Indonesia produces large amount of household solid waste production, namely 2.5 kg per day. Vermicompost is the best alternatives, the cheapest and does not harm the environment. In this study, the vermicompost method was used, worm weight and ratio affected the N, P, and K content in the fertilizer. The results of the sample test, namely the vermicompost time variable, the highest content was obtained at week 7 with N of 0.45%; P of 0.25%; and K by 0.23%. In the variable weight of worms, the highest weight of 300 grams of worms with N of 0.41%; P of 0.34%; and K by 0.23%; and the last variable is the ratio of cow dung and vegetable waste, where the highest content is at a ratio of 1:3 with N of 0.42%; P of 0.27%, and K of 0.22%. The test in this study was taken with 2 samples of the same variable and 1 different variable to determine the effect of these different variables on the N, P, and K content of liquid compost. Then the samples were tested for content using the macro-Kjedahl method to determine the nitrogen content, UV/Vis spectrophotometry to determine the phosphorus content, and AAS to determine the total potassium content.

Community Empowerment: Processing Household Organic Waste into Compost Using the Takakura Technique

Household organic waste is produced from household activities every day. This garbage contains high water and rotten youth. High volume causes a buildup that pollutes the environment and becomes a disease outbreak. Improper management techniques can have negative impacts on health and the environment. An alternative to processing organic waste generated from household activities is composting, which turns household waste into compost. The process of composting can be done with the Takakura technique. The activities aimed to increase community knowledge in household organic waste management and provide skills in utilizing organic waste into compost using the Takakura method for one week. The methods used were education, training, and assistance in making compost using the Takakura method to residents and health cadres of RW 06 Sutorejo Village, Mulyorejo, Surabaya, totaling 14 people. The activity results showed that community and health volunteers could understand household organic waste and composters and could make compost from household organic waste using the Takakura method. This change in knowledge is evidenced by the increase in before and after education and the increase in participants' skills in making compost. Making compost from organic waste with the Takakura method is economical for every citizen and does not require high costs. Based on this service activity, continuous socialization and assistance are needed for residents to utilize household organic waste.

Advances in gas-to-liquid technology for environmentally friendly fuel synthesis: Analytical review of world achievements

Problems of energy security, diversification of energy sources, and improvement of technologies (including alternatives) for obtaining motor fuels have become a priority of science and practice today. Many scientists devote their scientific research to the problems of obtaining effective brands of alternative (reformulated) motor fuels. Our scientific school also deals with the problems of the rational use of traditional and alternative motor fuels.This article focused on advances in motor fuel synthesis using natural, associated, or biogas. Different raw materials are used for GTL technology: biomass, natural and associated petroleum gases. Modern approaches to feed gas purification, development of Gas-to-Liquid-technology based on Fischer–Tropsch synthesis, and liquid hydrocarbon mixture reforming are considered.Biological gas is produced in the process of decomposition of waste (manure, straw, grain, sawdust waste), sludge, and organic household waste by cellulosic anaerobic organisms with the participation of methane fermentation bacteria. When 1 tonne of organic matter decomposes, 250 to 500–600 cubic meters of biogas is produced. Experts of the Bioenergy Association of Ukraine estimate the volume of its production at 7.8 billion cubic meters per year. This is 25% of the total consumption of natural gas in Ukraine. This is a significant raw material potential for obtaining liquid hydrocarbons for components of motor fuels.We believe that the potential for gas-to-liquid synthetic motor fuels is associated with shale and coalfield gases (e.g. mine methane), methane hydrate, and biogas from biomass and household waste gases.

Valorization of Human Urine with Mixed Microalgae Examined through Population Dynamics, Nutrient Removal, and Biogas Content

The majority of nutrients in municipal wastewater originate from urine. However, when flush water is used, the urine is diluted and mixed with other organic household waste, losing its high-value stream content. This study investigated the effect of source-separated human urine on the population dynamics, nutrient removal, growth, and biogas content of mixed microalgae grown in 250 L raceway ponds. Overall, a maximum biomass concentration of 1847 mg/L was reached, with up to 90% nitrogen and 80% phosphorus removal efficiencies, along with 254.96 L/kg vs. biogas production. The microbial community analysis identified Chlorella sorokiniana (Chlorophyta, Trebouxiophyceae) as the species with the highest abundance, after confirmation with four different markers (16S rRNA, 18S rRNA, 23S rRNA, and tufA). Moreover, principal component analysis was applied to capture the effect of environmental factors on culture diversity. The abundance of Chlorella sorokiniana increased almost sevenfold when the culture was exposed to open systems compared to the small-scale study carried out in 1 L Erlenmeyer bottles in laboratory conditions, both grown in urine and synthetic media (BBM). In conclusion, the present study contributes to the potential to valorize urine with microalgae by showing its high biogas content, and reveals that microalgae can adapt to adverse environmental conditions by fostering their diversity.
