household waste
Recently Published Documents

The problem of removing and neutralizing household waste is becoming more acute every year and occupies the main place for any city. This is explained by the fact that waste negatively affects the environment and the person who is the producer of this waste and causes great harm to the economy. On the other hand, the waste itself is the richest source of secondary resources, it is also a free energy carrier since household waste is a renewable energy raw material for fuel energy. The state of the environment on the territory of Russia is determined by a high technical load, as well as a long-term and sustained negative impact, including due to the formation and accumulation of production and consumption waste. Of all the garbage produced in Russia, the largest share falls on solid household waste - more than 25%. Only 3-5% of them are sent for recycling, and the rest - in a landfill. The situation in the field of waste management in St. Petersburg and the Leningrad Region and the presence of many unauthorized dumps causes serious public concern. The article formulates recommendations to improve the efficiency of organization and management of municipal waste management, addressed to the heads of state and municipal authorities and management.

The dataset contains records of small mammals (Eulipotyphla and Rodentia) collected in the background (unpolluted) areas in the vicinity of Karabash copper smelter (Southern Urals, Russia) and the territory of the Sultanovskoye deposit of copper-pyrite ores before the start of its development. Data were collected during the snowless periods in 2007 (18 sampling plots), 2008–2010 (13 plots annually), 2011 (30 plots) and 2012–2014 (19 plots annually). The capture of animals was carried out in different types of forests (pine, birch, mixed and floodplain), sparse birch stands, reed swamps, marshy and dry meadows, border areas, a household waste dump, areas of ruderal vegetation and a temporary camp. Our study of small mammals was conducted using trap lines (snap and live traps). During the study period, 709 specimens of small mammals were caught, which belonged to five species of shrews and 13 species of rodents. The dataset may be highly useful for studying regional fauna and the distribution of species in different habitats and could also be used as reference values for environmental monitoring and conservation activities. Our dataset contains new information on occurrences of small mammals. It includes the peculiarities of their habitat distribution in the background areas in the vicinity of the large copper smelter and the deposit of copper-pyrite ores before the start of its development (Chelyabinsk Oblast, Russia). All occurrence records of 18 mammal species with georeferencing have been published in GBIF.

Purpose In less than a decade to sustainable development goals (SDGs) there is a threat of household waste emanating from sub-urban sprawl especially in developing countries. Private approaches with government-enabling environments have been proved a successful platform for urban services such as housing provision and telecommunication in developing cities. Still private solid waste management (PSWM) seems different in Nigeria. Therefore, this paper aims to investigate the possible perceived hindrances facing PSWM organisations and proffer feasible policies to enhance sustainable clean and healthy cities. Design/methodology/approach Seven communities within Benin City sub-urban environs were adopted as the study area to accomplish the research’s objectives via a phenomenology type of qualitative research design. The study analysed the collated data from the knowledgeable participants via a thematic approach. Findings Lax legislative, absence of institutional framework, inadequate economic motivation, inadequate technical operations, among others, emerged as the encumbrances faced by PSWM firms. Wastes dumped along unethical locations such as streets, roads, uncompleted buildings, culverts and drainage channels, and undeveloped plots emerged as the encumbrance outcomes. Findings show that proffering feasible policy solutions to tackle identified hindrances can promote the achievement of SDGs across semi-urban locations in Nigeria. Research limitations/implications This research is restricted to urban household waste management by PSWM within Nigeria. Also, the study identified the challenges and proffer policy solutions to enhance improved clean environment within the sub-urban and urban cities. Practical implications As part of this study’s implications, results from this research intend to guide government policymakers and PSWM firms to encourage collaboration in designing appropriate strategic and educational programmes for the householders (customers) in sub-cities. It will be achieved via feasible policies that are tailored towards achieving sustainable health and environment-friendly sub-urban locations. Originality/value This paper intends to enhance proper PSWM and create sustainable cities via collaboration. Also, the paper engaged key stakeholders via a qualitative research design to proffer possible solutions to the menace of sub-urban and urban household waste management.

Islands are tightly connected to globalized material flows, with specific constraints and vulnerabilities. They are not closed metabolic loops of consumption, production, and waste, favorable to the circular economy. Small islands allow the observation of the material outcomes of circulation, from overflowing dumpsites to marine debris washing up on the shore. We argue that islands are key territories for better understanding the Capitalocene, precisely because of the ways in which they are connected to (rather than isolated from) globalized material flows. This article is a comparative geographical analysis of waste realities in three French/formerly French island territories: Ndzuwani (Comoros), Réunion, and New Caledonia. It builds on metabolism analysis and waste studies—in particular waste colonialism—to address the different perspectives that these approaches open up for the study of island territories. The long-term sociohistorical context of each island helps to explain contemporary waste management policies and practices. A material flow analysis makes it possible to sketch out metabolic profiles that show the contribution of prevailing mining and agricultural industries to waste generation. The comparison of current situations regarding household waste discourses and economies shows how these territories are characterized by waste accumulation.

To determine the origin and the processes of groundwater mineralization in the Mbeubeuss lake area, the major ion concentrations of the groundwater were compared to those of the rainwaters which constitute the input function of the aquifer of the Quaternary sands in the area of lake Mbeubeuss. The physico-chemistry of groundwater near the public discharge and its surroundings, has shown that the true value of the electrical conductivity of waters are around 2000 µS/cm. Values of electrical conductivity greater than 2000 µS/cm would represent the particular mineralization of ground waters by the public discharge of lake Mbeubeuss. The chemical facies of ground waters are dominated by the sodium and potassium chloride and calcium chloride facies. The study of the relationship between the major chemical elements and the chloride ion and the representation in the modified Chadha diagram of the chemical analyzes of ground waters from the campaigns of July 1998, July 2002 and March 2003, made it possible to highlight the different sources and processes controlling the mineralization of ground waters in the Mbeubeuss Lake area. Despite the proximity to the sea which suggests a considerable contribution of salts by aerosols and sea spray, the mineralization of ground waters in the area of lake Mbeubeuss is largely due to leachate from household waste and the influence of old sediments of the dry lake Mbeubeuss. The main processes controlling the mineralization of ground waters are marine contributions (aerosols and sea spray), dissolution-precipitation of minerals from the aquifer matrix, atmospheric CO2 diffusion, base exchanges, dilution-concentration and anthropogenic pollution.

In the civil engineering field, the incorporation of chemical admixtures is now a practical technics' used for improving the properties of concrete, such as improved workability, decreasing the water demand, increasing strength, etc. However, chemical admixtures have some disadvantages such as environmental pollution during both their manufacture and their use, else, there are rare somewhere. Because of this background, bio-admixtures appear principally useful, due to their environmental effect and friendly properties, bio-admixtures are substances obtained from a biodegradable product also resulting from the methanisation. The objective of this research is the valorization of household waste used as a bio-admixture. Moreover studying its effect on cement path workability, start/end of the cement setting.

In response to international trends regarding the reduction in plastic waste (or plastic pollution), this work used the official statistics that were recently released, focusing on regulatory actions restricting the use of plastic products and/or the increase in recycling in Taiwan. In addition, the impacts of the COVID-19 pandemic on plastic waste generation and plastic products’ recycling were also addressed in the present study. The results showed that the plastic compositions in the garbage slightly increased in recent years, suggesting that the effect of restrictions on the use of plastic products in Taiwan was not significant, even though the regulatory measures have been implemented since 2002. However, chlorine contents in the garbage were significantly increased in 2020. The increase could be attributed to the fact that kitchen waste (containing salt), household waste containing disinfectant (e.g., chlorine dioxide, sodium hypochlorite) or PVC-made products were generated more during the COVID-19 pandemic. Furthermore, the data also indicated that the monthly quantities of recycled plastic containers and other plastic products had no significant change since January 2020, especially in the outbreak period from May 2021 to July 2021.

The purpose of this activity is to convey the success of the Kopeling youth program (Community Care for the Environment) along with all the people who have supported them, especially those in the RT.05/RW.05 Kelurahan Sumber to convert household waste into compost and catfish farming feed to have a selling value. The research method uses a qualitative approach with the Participatory Research Appraisal research design through the Participatory Rural Appraisal method. This research was conducted on Kopeling youth and communities in the neighborhood RT.05/RW.05 Kelurahan Sumber. The findings obtained from this activity are that Kopeling and related communities have active participation and real motivation to minimize the problem of piles of garbage, especially household waste, to be something of economic value.

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.
