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).

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.

The relationship between economic growth and environmental impact has become a recurrent subject of research in recent years. Currently, results that indicate that the accumulation of economic growth leads to a reduction in environmental impact coexist with others that do not show any evidence in this respect. This paper aims to analyse this relationship using Material Flow Analysis through the two most frequent methods: territorial or production and consumption. For this purpose, data from China, the United Kingdom and the USA from 1990–2017 are used. The results show that the method used influences the conclusions, mainly due to differences in the accounting of physical trade flows. The production method, in which physical trade flows coincide with monetary trade flows, tends to underestimate the material consumption of rich, importing countries, while overestimating that of exporting countries. Policies based on this method have limited capacity to reduce global environmental impacts. The consumption method allows the environmental impact to be allocated to each country in a way that is more in line with its true material requirements.

The unprecedented technological development and economic growth over the past two decades has resulted in streams of rapidly growing electronic waste (e-waste) around the world. As the potential source of secondary raw materials including precious and critical materials, e-waste has recently gained significant attention across the board, ranging from governments and industry, to academia and civil society organizations. This paper aims to provide a comprehensive review of the last decade of e-waste literature followed by an in-depth analysis of the application of material flow analysis (MFA) and life cycle assessment (LCA), i.e., two less commonly used strategic tools to guide the relevant stakeholders in efficient management of e-waste. Through a keyword search on two main online search databases, Scopus and Web of Science, 1835 peer-reviewed publications were selected and subjected to a bibliographic network analysis to identify and visualize major research themes across the selected literature. The selected 1835 studies were classified into ten different categories based on research area, such as environmental and human health impacts, recycling and recovery technologies, associated social aspects, etc. With this selected literature in mind, the review process revealed the two least explored research areas over the past decade: MFA and LCA with 33 and 31 studies, respectively. A further in-depth analysis was conducted for these two areas regarding their application to various systems with numerous scopes and different stages of e-waste life cycle. The study provides a detailed discussion regarding their applicability, and highlights challenges and opportunities for further research.
