In 2021, the situation with the collecting, processing and disposal of waste in general, solid waste in particular, remains difficult in Ukraine and needs to be solved immediately. Soil contamination, as well as contamination of surface and ground waters by filtration effluents (or filtrates), is one of the most dangerous consequences of non-regulatory disposal of solid household waste.

Solid waste management is the process of collecting and treating solid wastes. It also offers solutions for recycling items that do not belong to garbage or trash. Reducing and eliminating the adverse impact of waste materials on human health and the environment supports economic development. Quality of life is the primary goal of solid waste management. To ensure environmental best practices, content or hazard potential and solid waste must be managed systematically, and it is needed to be incorporated into ecological planning. This study aimed to assess Bonbon, Clarin, Bohol residents towards the proper implementation of solid waste management. The quantitative-descriptive method of research was used with the aid of a modified standardized survey questionnaire. The data showed that mothers or married respondents aged 21-30 got the highest percentage. Therefore, it shows that they are the ones primarily in charge of household waste management. The Assessment of the implementation of Solid Waste Management was conducted per dimension: Planning and Control, Zero Waste Collection Service, and Waste Disposal System. According to the results, the dimension of Planning and Control was labeled as Strongly Implemented, Zero Waste Collection Service was marked as Moderately Implemented, and Waste Disposal System was categorized as Moderately Not Implemented. Therefore, it shows that the Solid Waste Management in Bonbon, Clarin, Bohol was moderately implemented. Thus, the study's outcome served as a guide to enhance their best practices for the full implementation and sustainability of solid waste management in their locality.

Communities store a potential power to support overall performance of urban solid waste management through various creative and innovative arrangements. In Indonesia, the Rukun Warga (RW) is the lowest hierarchy of community organizational system which can implement creative and innovative arrangements to support solid waste management activities with less financial requirement. This study observed RW-based activity on fifty RWs with 412 respondents in terms of 3Rs, household waste separation, waste recycling business and waste bank system undertaken by the community for the sake of cleanliness and income-earning. The result shows that the correlation between level of the activity of the RWs communities in undertaking 3Rs, recycling business and waste bank, and the perceived cleanliness by the community members was validated. It is also showed positive results such as improved urban environment and provided strong push-factor influencing the community members to join the movement and the activities towards sustainable solid waste management are not always cost-intensive activities but a socially bounded engagement would also workable.

Kampung Rawajati di Jakarta yang menerapkan sistem pengelolaan sampah berbasis masyarakat merupakan alternatif upaya mengatasi sampah rumah tangga. Penelitian ini bertujuan mengetahui pengaruh sistem tersebut terhadap penurunan berat sampah rumah tangga. Dengan desain studi potong lintang, penelitian ini dilakukan pada sampel 175 ibu rumah tangga yang dipilih secara acak. Hasil penelitian ini menunjukan bahwa pengelolaan sampah berbasis masyarakat dapat menurunkan berat sampah sebesar 28,3%. Analisis regresi linier ganda memperlihatkan bahwa kegiatan pengelolaan yang berpengaruh terhadap penurunan berat sampah adalah kegiatan reuse, daur ulang, dan pembuatan kompos (nilai-p < 0,05). Pembuatan kompos merupakan variabel yang berkontribusi terhadap penurunan berat sampah 657,3 gram setelah dikontrol variabel perancu. Penurunan berat sampah ditemukan lebih besar pada rumah tangga yang mendapat pelatihan. Tidak ada perbedaan penurunan berat sampah menurut jumlah anggota keluarga, penghasilan rumah tangga, dan pengetahuan ibu. Disarankan agar Pemerintah DKI Jakarta dapat melakukan replikasi model pengelolaan sampah berbasis masyarakat kepada wilayah lainnya, dengan memberikan pelatihan pengelolaan sampah kepada masyarakat.Kata kunci : Pengelolaan sampah berbasis masyarakat, berat sampah, pengolahan dan minimasi sampahAbstractKampung Rawajati in Jakarta applies community-based solid waste management system as an alternative way to overcome household waste problem. The objective of the research is to assess the effect of community-based solid waste management on reduction of household waste weight. This study has crosssectional study design and was conducted on 175 housewife as respondent who were selected randomly. The data was collected by interview using structured questionnaire and weighing of household waste. The result shows that the community-based solid waste management can reduce 28.3% of household waste weight (weight before: 1.845 gram/house/day and after: 1.324 gram/house/day). Multiple linear regression analysis shows that variables affecting thereduction of solid waste including re-using activity, recycling, and composting (p-value <0.05). Composting represents the biggest effect to reduction (657.26 gram) after controlled by potential confounders. The reduction was higher among household with waste training and number of trained household member. It was found that number of family member, family income, and mother knowledge are not significant. It was recommended to the Government of DKI Jakarta to replicate this community-based waste management system to other regions by providing training facilities on solid waste management.Keywords: Community-based on solid waste management, waste weight, processing and minimizing of solid waste

Abstract Production of refuse derived fuel from municipal solid waste in future shall play a strategic role in an integrated waste management system. The amount of landfilled biodegradable materials thus will be diminished according to provisions of the 1999 Waste Landfill Directive. The aim of this article is to evaluate cost effectiveness based on cost evaluation of the different complication of the waste pre-treatment equipment complectation and based on regenerable waste quantities in Latvia. The comparison of cost estimates is done in 3 scenarios considering potential waste quantities in Latvia: Scenario I - planned annual waste quantity is 20 kT; Scenario II - 40 kT and Scenario III - 160 kT. An increase in amount of waste and processing capacity means the decrease in costs of mechanical pre-treatment of 1 ton of waste. Thus, costs of mechanical sorting line under different scenarios with capacities of 10 t h-1, 20 t h-1 and 80 t h-1 are EUR 32 per t, EUR 24 per t and EUR 15 per t, respectively. Most feasible cost for a set of mechanical pre-treatment equipment for the capacity of 10 t h-1 is EUR 32 per t by using rotating drum screener with the following manual sorting. Mechanical pre-treatment equipment of unsorted municipal waste is economically nonbeneficial, when the use of fine (biologically degradable) fraction is not possible. As the sorting of biodegradable kitchen waste is not developed under the current waste management system in Latvia, the lines for mechanical pre-treatment of household waste would be better to install in landfills.

AbstractMany cities in developing countries lack adequate drainage and waste management infrastructure. Consequently, city residents face economic and health impacts from flooding and waterlogging, which are aggravated by solid waste infiltrating and blocking drains. City governments have recourse to two strategies to address these problems: a) ‘hard’ infrastructure-related interventions through investment in the expansion of drainage and waste transportation networks; and/or, b) ‘soft’, low-cost behavioural interventions that encourage city residents to change waste disposal practices. This research examines whether behavioural interventions, such as information and awareness raising alongside provision of inexpensive street waste bins, can improve waste management in the city. We undertook a cluster randomized controlled trial study in Bharatpur, Nepal, where one group of households was treated with a soft, low-cost intervention (information and street waste bins) while the control group of households did not receive the intervention. We econometrically compared baseline indicators – perceived neighbourhood cleanliness, household waste disposal methods, and at-source waste segregation – from a pre-intervention survey with data from two rounds of post-intervention surveys. Results from analysing household panel data indicate that the intervention increased neighbourhood cleanliness and motivated the treated households to dispose their waste properly through waste collectors. The intervention, however, did not increase household waste segregation at source, which is possibly because of municipal waste collectors mixing segregated and non-segregated waste during collection. At-source segregation, a pre-requisite for efficiently managing municipal solid waste, may improve if municipalities arrange to collect and manage degradable and non-degradable waste separately.

Abstract Chilean legislation dictates that Municipalities are responsible for household solid waste management, but this doesn’t include the clean-up of illegal dumpsites. These in-city dumpsites usually are located on public roads, parks or abandoned sites; have a wide variety of origins, from household trash to business waste, and feature a high component of construction debris. One of the main problems that municipalities have managing these sites is that when they are cleaned, the dumpsites immediately reappear. Therefore, a site survey and visual characterization was performed for these illegal dumpsites at the Municipality of La Granja, and a cost analysis associated with the constant clean-up costs was performed. La Granja Municipality has an established clean-up program with a frequency that varies from one to three withdrawals a week per dumpsite. Santiago is Chile's capital and is divided into 32 municipalities, the general population of the city is 5.250.565 habitants according to the 2017 census. La Granja is one of Santiago’s municipalities; according to the last census, it has 116.571 inhabitants and a total of 34.423 households divided into 69 neighbourhoods. The social economical income of the municipality corresponds to medium low to lower level. The study detected 35 critical sites that were catalogued as recuring dumpsites. The mayor cause of these dumpsites corresponds to illegal dumping of construction waste, mayor appliance and household waste, and only one dumpsite didn’t present construction debris during the length of the study. The average volume measured in site, for most of the dumpsites varied from 1 to 3 m3 and only 2 sites exceeded 8 m3. The most important characteristics of the dumpsites were the ease accessibility (82,4%), followed by the total lack of public illumination, high vehicular traffic and to or more intersections (67,7%). The equipment and personnel cost were estimated for the clean-up service of the 35 dumpsites. The cost analysis showed that the associated cost of the clean-up corresponds to a 5,8% of the municipal budget for solid waste management. As a result of the study, 4 sites were intervened through the generation of green area or small parks, with an emphasis in the protection or blocking of the access and roadside.

At present, processing and recycling of municipal solid waste (MSW) has become more relevant in our country and the world at large. This problem concerns large towns and cities, where every year millions of tons of all kinds of fractions of household waste are produced. Disposal or recycling of solid waste is an environmental issue, but it is associated with the solution of complex technical, energy and economic challenges. The purpose of this study is to identify the advantages and disadvantages of modern methods of processing and disposal of MSW with the prospect of developing and creating a device for recycling MSW taking into account modern approaches to energy saving and environmental protection. The main results of the study are to create a simple, reliable and technically sound method of MSW disposal to obtain additional energy. The significance of the results obtained for the construction industry is the design of a device for the disposal of solid waste with the production of solid combustion products and further their use as building materials and products for various purposes. Because of the technological process of MSW processing, it becomes possible to generate some returns through use of resulting thermal energy for electricity production.
