Domestic Solid Waste Management in Rural Areas - case study of the Waorani Nampa Community, Ecuadorian Amazon

: This study focused on the proposal of an integrated solid household waste management system in the rural community of Waorani Nampa belonging to the Waorani indigenous nationality in the Ecuadorian Amazon. In this community, the burning of domestic solid waste is the only man-agement strategy commonly used, which has generated diverse environmental and health im-pacts on the population. Therefore, here we focused on diagnosing the socio-environmental con-dition of the community through surveys in order to determine the average daily per capita pro-duction of domestic solid waste. This was done through a characterization applying the method-ology of the Pan American Health Organization (PAHO) and the development of a proposal for a management model appropriate to the current demographic characteristics, from environmental education to final disposal. The results obtained determined that the average PPC of the community is 0.343 kg/person/day and the predominant category was the organic fraction with 64.20% of a total of 31.15 kg of solid waste produced. Finally, as initiatives for adequate management and use, it was proposed that an area be adapted to generate compost and a recycling system to obtain economic resources for the benefit of the population.

How does digital governance affect the level of domestic waste separation for rural residents? Empirical evidence from rural areas in Jiangsu Province, China.

The management of rural domestic waste is directly related to the quality of China's rural habitat and the ecological security of the countryside, and is one of the important tasks of rural revitalization. Based on the perspective of digital technology empowering rural governance, this study uses the China Land Economic Survey (CLES) data to empirically test the impact of digital governance on the level of domestic waste separation for rural residents by constructing the ordered probit model. The results show that in the process of rural governance modernization, digital governance helps to improve the level of domestic waste separation for rural residents in the process of rural governance modernization, and the findings still hold after robustness tests. Mechanistic tests showed that digital governance can impact the level of domestic waste separation for rural residents through cadre-mass relationship and institutional trust. The findings of this study provide a new perspective on good environmental governance in China's countryside and have important implications for promoting the improvement of rural habitat quality.

THE IMPLEMENTATION OF DOMESTIC SOLID WASTE CLASSIFICATION OF AT RESOURCES IN PHAN DINH PHUNG WARD, THAI NGUYEN CITY, VIETNAM

Domestic waste is gradually becoming one of the sources of severe environmental pollution. Phan Dinh Phung ward is one of the central wards of Thai Nguyen city, with a dense population, so the amount of domestic waste in the ward is large. This study was conducted to assess the current status of domestic waste classification at the source to have a basis for proposing practical solutions to improve the efficiency of domestic waste management in Phan Dinh Phung ward. The methods used in this study include document analysis and synthesis, sociological investigation, and data processing. Research results show that: Phan Dinh Phung ward (Thai Nguyen city) has been classifying domestic waste at sources since 2018. Currently, 100% of households and business households in the ward do this. Segregation of domestic waste at sources; 98.7% of households put garbage in the right place; 89% of households know how to sort garbage; 57% of households carry out the classification of household waste. The proportion of households doing the correct classification is 45%. However, the number of households using garbage sorting tools distributed for the proper purposes and dumping the garbage on time is still low. For the waste separation at the source in Phan Dinh Phung ward to be more effective and to attract the participation of the people, it is necessary to perform synchronously from waste classification at the source to the collection. Transportation and treatment in the following directions: Sorting at the right source, collecting correctly, treating effectively, and conducting propaganda more often to the people.

Decomposition and humification process of domestic biodegradable waste by black soldier fly (Hermetia illucens L.) larvae from the perspective of dissolved organic matter

Black soldier fly larvae (Hermitia illucens L.) (BSFL) bioconversion is a promising technology for domestic biodegradable waste (DBW) management and resource recovery. However, little is known about the DBW biodegradation during the BSFL bioconversion from the perspective of dissolved organic matter (DOM). In the current study, field tests were conducted on a full-scale BSFL bioconversion facility with treatment capacity of 15 tons DBW/day. Composition of DOM in DBW were investigated by spectral analysis (UV–vis, fluorescence, and Fourier Transform Infrared spectroscopy (FT-IR)), coupled with enzyme activity analysis. After BSFL bioconversion, DOM concentrations, total carbon and total nitrogen in residues decreased by 51.5%, 18.3% and 19.9%, respectively. Meanwhile, enzymes like catalase, lipase, protease, sucrase, urease and cellulase significantly increased (9.28%–56.3%). The specific UV absorbance at 254 nm and 280 nm (SUVA254, SUVA280), the area at 226–400 nm (A226-400) and slope in the 280–400 nm region (S280-400) of DOM increased by 230%, 186%, 143% and 398%, respectively. Moreover, the characteristic peaks at 1636, 1077 and 1045 cm−1 in FT-IR increased continuously, with a significant decrease in peak at 1124 and 1572 cm−1. DOM spectral data show that BSFL decomposed the carboxylic, cellulose and aliphatic components, resulting in the increase of oxygen-containing functional groups (e.g., hydroxyl, carboxyl, carbonyl) and aromatic compounds. Furthermore, fluorescence profiles show that Region Ⅰ, Ⅱ (aromatic proteins) and Ⅳ (soluble microbial byproducts) decreased while Region Ⅴ (humic-like substances) increased significantly. Humification index increased by 122% while biological index decreased by 18.0%, indicating a significant increase in degree of humification and stabilization of the residues. The current evidence provides a theoretical basis for technical re-innovation and improving economic potential of BSFL technology.

Regulatory Obstacles in Municipal Solid Waste Management in Kazakhstan in Comparison with the EU

In the context of achieving the goals of the modern environmental agenda, the issue of effective management of household waste is a complex problem, being one of the highest priorities on a global scale. Regional features and the lack of effective international instruments often hinder the solution of this problem, complicating the development and application of common mechanisms. For Kazakhstan, which is the largest country in Central Asia and the state that produces the largest amount of household waste in the region, the issue of managing household waste is of particular relevance. This study is on the prospects for political and legal regulation in matters of municipal waste management in Kazakhstan within the framework of the use of foreign legal instruments and practices. Besides that, the study examines the prospects for the management of solid domestic waste in the country. Based on the study of foreign experience in the management of domestic waste, we identified the shortcomings of the existing legislative regulation in this area in the Republic of Kazakhstan. The analysis showed that the legislation of the Republic of Kazakhstan in the relevant area is at the stage of formation. At the same time, the existing problems require a comprehensive solution related to the development of an integrated approach, which implies the effective interaction of political and legal instruments. In particular, the use of national strategies and programs, integrated waste management programs, and the development of an appropriate regulatory framework for them. A review of political initiatives that directly affect the prospects for the formation of legal regulation indicated the commitment of the subjects of policy making in the field of environmental protection of the Republic of Kazakhstan to approaches based on the preference for minimizing or preventing waste generation and for the waste-to-energy principles. These initiatives are in line with the environmental policies in the EU.

Occurrence analysis and scenario development for domestic solid waste management in Vung Tau City

Domestic solid waste management (DSWM) in Vung Tau City (VTC) is emerging as an envi-ronmental problem behind rapid urban development. The amount of DSW increased rapidly, leading to a disturbance in the collection, transportation, and challenges in the implementation of DSWM at the source. This study aims to assess the situation and develop and analyze the scenarios of the DSWM system for VTC, thereby proposing strategies to improve the DSWM system for the city in 2024 - 2033. The scenarios of the DSWM system were built based on the situation analysis, the national and regional SWM regulations, and scientific assumptions that have been studied in Viet Nam. This study showed that the amount of DSW in VTC has in-creased rapidly at the rate of 7,4%/year over the past decade and reached 457.9 tons in 2022. About 80% of the DSW is collected by 500 informal collectors, who work spontaneously and are unmanaged. The minimalist and optimal DSWM models have been built and evaluated. The results showed that these two models of the DSWM should be applied in two phases, 2024-2028 and 2029-2033, respectively. According to this roadmap, the amount of DSW to the land-fill was estimated to reduce 26% of the total waste generation. The amount of recovered recy-clable waste is also estimated to be increased five times compared to 2023. Furthermore, the quality of DSW in the treatment area is suitable for composting and handling by waste-to-energy solutions.

Chronic Undernutrition and Associated Factors Among Children Aged 6 to 59 Months in South Ari, South Omo Zone, Ethiopia: A Community-Based Cross-Sectional Study.

Chronic undernutrition (stunting) among children is associated with an increased risk of morbidity and mortality. The global community is committed to end all forms of malnutrition by 2030. Regardless of this, children are suffering from some form of malnutrition but the reason is unclear. This study thus was intended to identify stunting and associated factors among children aged 6 to 59 months in the South Ari Woreda of South Omo Zone. A community-based cross-sectional study was conducted in South Ari Woreda from 1, January 2022 to 30, February 2022, and 409 children participated. A simple random sampling technique was used to identify study participants, and mothers/caregivers were interviewed. Data on sociodemographic, economic, and environmental determinants were collected by trained professional nurses using interviewer-administered questionnaires and anthropometric data were collected via weighting and measuring the height/length of the child. Emergency Nutrition Assessment for Standardized Monitoring and Assessment of Relief and Transitions 2020 software was used to generate an anthropometric index, and a child with a height for age index below -2standard deviations of the standard population was considered stunted. Factors of stunting were assessed using multivariate binary logistic regression at a 5% significance level. The study revealed that 44.0% (95% confidence interval (CI) = 39.19%-48.81%) of children were stunted in the study area. Household's wealth status (the poorest; adjusted odds ratio (AOR) = 4.14 [95% CI = 2.08-8.22] and poor; AOR = 3.31 [95% CI = 1.60-6.82]), improper solid waste management practice of the household (AOR = 2.67 [95% CI = 1.56-4.55]), and the children sleeping under insecticide-treated bed nets (ITN) (AOR = 0.37 [95%CI = 0.22-0.60]) were statistically significantly associated with stunting status of the children. Stunting among the children in the study area was very high. Improving household's (HH) economy, safe management of domestic solid waste, and ensuring that the children are sleeping under ITNs are expected to reduce stunting.

Solving the Urban Domestic Waste Classification Dilemma from a Coalitional Game Perspective

The effective classification of urban domestic waste is the key to achieve a “waste-free city” and provides an essential guarantee for resource utilization. This article takes a coalitional game perspective to study the dilemmas in urban domestic waste separation from the cooperative interaction of residents, government, and enterprises. The study finds that urban domestic waste classification in China is currently facing many problems, focusing on: 1) insufficient consensus among residents, 2) shortage of input funds, 3) corporate profitability difficulties, 4) weak policy constraints, and 5) difficulties in integrating goals. In this regard, each participating body still needs to focus on collective interests, coalitional games, break the dilemma society, and promote the long-term management of urban domestic waste.

Formulation and Nutrient Assessment of Poultry Feed from Domestic Waste and Its Effect on The Growth of Poultry Birds

Poultry feed from locally generated domestic waste in Bayelsa State was formulated and compared with the commercially available feed (Top feed). The waste materials used for the local formulation were; Yam peel, Prawn head, Pineapple peel, Avocado Pear peel, Coconut Chaff, Fish head, Crayfish chaff. Proximate composition, vitamins, mineral and anti- nutrient contents of the local formulae as well as the commercially available feeds was evaluated using standard methods and results obtained were compared with each other. Results shows that the nutrient composition of the local feeds formulated from waste material compares favourably well with that of the commercial feed with anti-nutrient (Tannins, Oxalate, Phytic acid, HCN) within FAO tolerable limits. Thirty (30) days feeding trial was conducted to evaluate the growth performance of the broilers fed on locally formulated feed from domestic waste compare with commercial poultry feed. Ten Forty-five (45) day old broiler were randomly allotted into two groups of five (5) birds each. The poultry birds were fed ad-libitum for a period of four weeks and weight gain where recorded every three days. Result shows the significant (P< 0.05) increase on the growth rate of birds fed with commercial poultry feed when compared with those fed with locally formulated feed from domestic waste. Despite this significant growth noticed in birds fed with commercial poultry formulae, it is evidence from the result that the locally made formulae contains lots of nutrients which can support growth of poultry birds and also devoid of additives promotion. Thus, utilization or incorporation of at least 20% of domestic waste in poultry feed can help reduce the cost of livestock production and also ameliorate the burden and dangers possess by the disposal and poor management of domestic waste in the environment while at the same time reducing the act of artificial growth substances added to commercial poultry feed.

Vinculación entre creencias y comportamientos para el abordaje de problemáticas ambientales

Management and disposal of domestic waste in rural locations often face difficulties, posing a potential environmental problem. Solving it implies valuing the relationship between the human being and the environment, to plan specific environmental education actions. The identification of both beliefs and behaviors of the population of Paso Hospital, (rural town in Rivera, Uruguay) regarding environment, is taken as a case study. 184 inhabitants were surveyed, the data was analyzed using the R program, performing chi-square tests, and calculating association coefficients (Cramer's V).  It is observed that the assessment of local environmental problems regarding the use of natural resources varies according to the educational level. There is a clear need to carry out deeper research to better understand the relationship between beliefs and behaviors concerning the environment, involving local people, analysis and communication of environmental impacts in the territories.

Management of domestic solid waste in rural communities – a case study of the Río Blanco community, Ecuador

The current study focused on the proposal of a comprehensive management system for domestic solid waste in the rural community of Río Blanco belonging to the indigenous Ecuadorian Kichwa nationality. In this community, the burning of domestic solid waste is the only management strategy commonly used, which has generated various environmental and health impacts on the population. Therefore, here we focused on diagnosing the socio-environmental condition of the community through surveys in order to determine the average daily per capita production of domestic solid waste. This occurred through a characterization applying the methodology of the Pan American Health Organization (PAHO) and in the development of a proposal for a management model appropriate to the present demographic characteristics, from environmental education to its final disposal. The results obtained determined that the average DPCP of the community is 0.205 kg/person/day and the predominant category was the organic fraction with 45.84% of a total of 23.62 kg of solid waste produced. Finally, as appropriate management and use initiatives, we proposed the adaptation of an area for the generation of compost and a recycling system that allows obtaining economic resources for the benefit of the population.

Analysis of Sanitation Technology for Waste Management and Drainage Using the Analytical Hierarchy Process (AHP) Method in Bangko City

Sanitation in Indonesia is defined as efforts to dispose of liquid waste and domestic waste to create a clean and healthy living environment both at the household and settlement levels Domestic waste management needs to be considered in managing a settlement Domestic waste products, especially those containing human feces, contain dangerous pathogens. If it is released directly into water bodies without processing it will result in environmental pollution Technology and knowledge are needed to accelerate the implementation of development states that technology options are highly dependent on technical and non-technical aspects; environmental factors, cultural and behavioral factors, as well as capital and recurring cost factors To analyze the choice of technology, determined based on perception using the Process Hierarchy Analysis (AHP) method. the AHP method can be used in determining sanitation technology in specific areas in order to obtain the most suitable sanitation technology for use in specific areas.

Knowledge, Attitude and Practice Towards Domestic Solid Waste Management in Rural District, Bac Lieu Province, Vietnam

The characteristics of waste composition and community behavior are important data for making an appropriate domestic solid waste management plan. However, these data are lacking or not studied in Bac Lieu, especially in rural areas. Therefore, the study was conducted to determine the domestic waste composition and evaluate the factors related to the knowledge, attitude and practice (KAP) level of the community in domestic solid waste management in Phuoc Long district, Bac Lieu province, Vietnam. The results of domestic solid waste samples collected at households showed that the waste was composed of organic (73.8%), recyclables (15.7%), hazardous waste (0.7%), and others (9.9%). Plastic bags (42.7%) and papers (30.5%) were predominant in the recyclables. The interview of 150 households indicated that the majority of respondents had an average level of knowledge (46%), and attitude (49.3%). However, 46% of respondents had an inadequate level of practice. In addition, the study observed that respondents have a good level of knowledge and attitude that leads to good practice. The Chi-square test showed that the KAP level of the respondents is influenced by demographic factors including age, education, occupation and income (p<0.05). In which, education level and age were the significant influencing factors. The results indicated that education for improving the community’s knowledge and attitudes in domestic solid management should pay more attention on the population aged over 60 years and those with occupations belonging to agriculture and housework.
