Electronic equipment is produced to meet human needs, so this will also have a significant impact on increasing the rate of e-waste generation in landfills in almost all countries. One of the environmental pollution issues that are of concern throughout the world is the management of e-waste (e-waste). This is due to the rapid increase in the use of electronic products. Thus, the existence of electrical and electronic equipment becomes shorter and becomes obsolete. The absence of information related to the volume of e-waste generation and material flow is one of the problems of the Indonesian government in managing e-waste. Therefore, the purpose of this paper is to calculate e-waste and analyze material flow. The method used in this study is Material Flow Analysis (MFA). Furthermore, a survey of household and informal sector respondents was used. The questionnaire adopted from UNEP was modified and distributed to 400 households and 54 informal sectors in DKI Jakarta. The results show the total rate of generation of e-waste produced aaproximately 7713.42013 kg/year. Furthermore, it is necessary to develop several strategies in order to avoid negative impact. This research can be information in filling the data limitations and management of sustainable e-waste in DKI Jakarta.

Material flow analysis can effectively trace and quantify the flows and stocks of materials such as solid wastes in urban environments. However, the integrity of material flow analysis results is compromised by data uncertainties, an occurrence that is particularly acute in low-and-middle-income study contexts. This article investigates the uncertainties in the input data and their effects in a material flow analysis study of municipal solid waste management in Maputo City, the capital of Mozambique. The analysis is based on data collected in 2007 and 2014. Initially, the uncertainties and their ranges were identified by the data classification model of Hedbrant and Sörme, followed by the application of sensitivity analysis. The average lower and upper bounds were 29% and 71%, respectively, in 2007, increasing to 41% and 96%, respectively, in 2014. This indicates higher data quality in 2007 than in 2014. Results also show that not only data are partially missing from the established flows such as waste generation to final disposal, but also that they are limited and inconsistent in emerging flows and processes such as waste generation to material recovery (hence the wider variation in the 2014 parameters). The sensitivity analysis further clarified the most influencing parameter and the degree of influence of each parameter on the waste flows and the interrelations among the parameters. The findings highlight the need for an integrated municipal solid waste management approach to avoid transferring or worsening the negative impacts among the parameters and flows.

The circular economy (CE) model has become highly relevant in recent years, with the electronics industry being one of the sectors that has considered its application. Despite only a limited amount of literature being available on waste electric and electronic equipment (e-waste) in Mexico, the Mexican Government, academic institutions, and electronics industry have coordinated efforts to implement the CE in the country. This study evaluates the current technical and economic situation of cellphone e-waste generated in Mexico by surveying and analyzing the main actors that influence the management of this waste and using a material flow analysis. Extensive fieldwork was conducted in order to quantify the extent of cellphone e-waste processing in both formal and informal channels. The study of printed circuit boards in cellphones shows that the total value of cellphone e-waste materials ranges between $11.277 and $12.444 million USD per year in Mexico. However, a value of only $0.677 million USD is recycled through formal channels. After characterizing the remanufacturing and recycling CE loops, we conclude that the potential for improvement and advancing towards a CE model is significant

Abstract This research was conducted to (1) determine the hazardous waste generation from the industrial sector in Indonesia in 2019, (2) predict the hazardous waste generation in 2040, and (3) determine the waste material flow. This study's secondary data comes from past studies related to hazardous waste management in Indonesia's industrial sector. In this study, predicting hazardous waste generation used 2 (two) methods: the Annual Average Growth Rate and the Unit Gross Industrial Output Value. The last method used the assumption that Micro and Small Enterprises (MSEs) generate 10% of the total hazardous waste in Indonesia's industrial sector, while the Medium and Large Enterprises (MLEs) generate 85% of the total hazardous waste. In 2019, the total hazardous waste generation reached 573,351,835.37 tonnes yr-1. The hazardous waste projection from Indonesia's industrial sectors in 2040 reached 1,066,603,307.02 tonnes yr-1 to 1,298,591,111.95 tonnes yr-1. Based on the Material Flow Analysis, 68.66% of the hazardous waste was managed by disposing 11% of the hazardous waste in landfill, utilizing 31.44% of the waste, while 31.37% of the hazardous waste goes to hazardous waste transfer depots, and only 1.24% of the hazardous waste was processed. Meanwhile, 31.34% of the hazardous waste is considered to be unmanaged and pollute the land. Thus, it is necessary to have a reliable and integrated hazardous waste management system to reduce the negative impacts on the environment and human health.

In recent decades there have been a significant increase in the use of electronic equipment in homes, offices and industries. When these equipment are discarded after have been used they become Waste of Electric and Electronic Equipment (WEEE). To know how the forecasting of WEEE´s generation were made, it was necessary to carry out a systematic review. The search was done in 5 databases by using the key words "electronic waste" or "WEEE" or "e-waste" and "forecasting" and it was found 854 articles. After applying the inclusion and exclusion criteria 28 articles were reached. As a result, it is noted that the selected articles are concentrated in the USA and China and in a few newspapers. The most independent variable used was the dada about the commercialization of the equipment. The majority of the articles have as variable response the unit and weight. There was also strong use of statistical tools and forecasting methods, especially the regression and the MFA (Material Flow Analysis).

The main sources of waste generation are: industry, municipal sector, and agriculture. Municipal waste is solid and liquid waste that arise in households, public utilities (trade, services, handicrafts) and municipal services (e.g. street cleaning and maintenance of green areas). The main aim of this paper are the analysis of the flow of municipal solid waste in Łódź Metropolitan Area, its composition, presentation of the process towards a more selective waste system, and the extraction of biodegradable waste from the MSW. The article is based on a report prepared within the Horizon 2020 project REPAiR “Resource Management in Peri-urban Areas: Going Beyond Urban Metabolism”.
