Assessment of Solid Waste Management at Source in Compliance With Guidelines Among Residents of Kawempe Division, Kampala, Uganda

Background: Solid waste management poses a big challenge for many urban households, municipalities and cities, especially in developing countries, partly due to increasing urbanization. Overcrowding and informal settlements have emerged with illegal and indiscriminate waste disposal. Guidelines for proper management of solid waste are least observed at house hold level in such settings. The purpose of the study was to assess solid waste management at source in compliance with guidelines among residents of Kawempe municipality Kampala district. Methods: It was descriptive and analytical cross-sectional study design, with both quantitative and qualitative methods. 385 households heads and four local leaders were interviewed using researcher administered questionnaires and interview guide. Results: The study found that only 37.9% of households complied with guidelines for solid waste management at source. Factors of waste management practices were waste reduction (p=0.005), separation (p=0.001), reuse (p=0.001) and composting (p=0.027). Determinants such as gender (p=0.007), marital status (p=0.016), level of education (p<0.0001), occupation (p=0.007), household size (p=0.025), medium of community sensitization (p<0.0001), enforcement of bi-laws (p=0.005), type of waste generated (p<0.0001) and waste storage method (p=0.009) were implicated. Conclusion: Compliance with guidelines in the management of household solid waste at source was still very low within the city. Authorities ought to intensify household solid waste management awareness campaigns.

A Study on Willingness to Pay of Household Solid Waste Management in Kureepuzha of Kollam District, Kerala

Since the origin of human beings, there exists a parallel waste generation. Human wants are unlimited; the generation of waste also differs. With the increase in industrial growth and urbanisation, waste generation was also going at an alarming rate. The improper disposal of waste will lead to a rise in the pollution level. It can be managed from the household level. So the study was based on the willingness to pay by the household for the household solid waste management and the reasons behind the non-willingness to pay.

Characterization and Analysis of Household Solid Waste Composition to Identify the Optimal Waste Management Method: A Case Study in Hanoi City, Vietnam

A survey on household solid waste generation and physical composition was conducted in Hanoi City, the capital of Vietnam. The study sampled 110 households in specific areas with different population density and household scale. Household solid waste was classified into 13 main categories and 25 sub-categories. The results showed that average generation rate of waste in Hanoi City is 0.63 kg per person per day with a slightly higher rate in rural areas than urban ones. The largest proportion was food and garden waste at 78.9% followed by plastic and paper. Plastic waste was segregated into plastic and nylon, and nylon was double that of plastics in household solid waste. Compared to previous studies, this study found a higher portion of organic matter in the waste characterization that could be attributed to the changes in lifestyle patterns associated with COVID-19. This situation provides challenges and opportunities for introducing biomass technology to recover energy.

Implementation of participatory pre-collection in the sustainable management of household solid waste: case of the district of Douala V in Cameroon

EPI sciences The main objective of this study in the district of Douala V is to set up participatory pre-collection of household solid waste which, by protecting the environment, promotes the recovery of this waste. More specifically, the aim was to make an inventory of solid waste management, to raise awareness of households on participatory pre-collection, to describe the technical organization of the service and to evaluate the parameters of financial analysis for a pre-collection activity. To do this, available documents, direct observations, interviews and survey form were used. The main results of this study showed that the daily production or ratio of one inhabitant of Douala V is 1.05kg/hab/jour; the annual production is estimated at 363,870 tons. The low collection rate of about 23% was observed. With regard to household sensitization, 43% of the households surveyed are willing to pay for the pre-collection service and 52% are against and 5% are uninformed. The provisional financial analysis is based on one year; the investment cost is estimated at 3 327 400 CFA (5079 €). Overall, it appears that the solid waste collection rate in Douala V is below average, so it appears that pre-collection and recovery of household solid waste have a major role to play in the solid waste management system. Cette étude déroulée dans l’arrondissement de Douala V a pour objectif principal de mettre sur pied la pré-collecte participative des déchets solides ménagers qui en protégeant l’environnement, favorise une valorisation de ces déchets. Il s’agissait plus spécifiquement de faire un état de lieux de la gestion des déchets solides, de sensibiliser les ménages sur la pré-collecte participative, décrire l’organisation technique du service et d’évaluer les paramètres d’analyse financière pour une activité de pré-collecte. Pour ce faire, des documents disponibles, observations directes, entretiens et fiche d’enquête ont été utilisés. Les principaux résultats de cette étude ont montré que la production journalière ou ratio d’un habitant de Douala V est de 1,05kg, la production annuelle est estimée à 363 870,45 tonnes. Le taux de collecte faible d’environ 23%. Pour ce qui est de la sensibilisation des ménages, 42,66% des ménages enquêtés sont prêts à payer pour le service de pré-collecte et 52,33% sont contre et 5% sont sans avis. L’analyse financière prévisionnelle est basée sur une année, le coût d’investissement s’estime à deux mille huit cent quatre-vingt-onze Euro (2 891 Euro). Il ressort globalement que le taux de collecte des déchets solides à Douala V est en dessous de la moyenne, il apparait donc que la pré-collecte et la valorisation des déchets solides ménagers ont un rôle majeur à jouer dans le système de gestion des déchets solides.
