Abstract Nowadays waste electrical and electronic equipment (WEEE) generation is increasing due to the increase in the number of users and the development of electronic products. In Indonesia, there are no specific regulations about WEEE even though it is identified as hazardous and toxic waste. This study aims to predict the WEEE generation from the most used and replaced electronic products by citizens of Bandung City. The data is collected by surveying 400 families in Bandung City. Based on the survey results, there are three types of electronic products that are most used and replaced by citizens of Bandung City, which are mobile phones, laptops and televisions. The Delay Model is modified by replacing the lifespan variable with end-of-life to project the mobile phones, laptops and televisions waste generation in Bandung City. The purpose of this modification is to adjust the pattern of electronic products used in developing countries. The projection results state that Bandung City will generate 0.61 tons/day of mobile phones, 8.66 tons/day of laptops and 3.16 tons/day of televisions at the end of 2020. Based on the results of the projection, WEEE management and recycling is important which can reduce WEEE disposal and increase the economic value of WEEE.

Survey Results

Modern day’s rapid development in technology has forced a shift in trends and popularity of electronic products. This causes early obsolescence of former technologies such as cathode ray tubes (CRT), leading to massive disposal in a short amount of time. To be able to predict this newly developing waste stream, a study on the generation of such electronic waste products is needed. In a case study focusing on Bandung, questionnaires to primary sources of e-waste such as households, offices, schools and laundromats were conducted to determine not only the number of e-products that is used and discarded, but also how e-waste is treated firsthand when it becomes unwanted. The e-waste generation predicted is about 65,000 units of CRT TVs per year, 19,000 CRT monitors per year and 48,000 washing machines per year. Survey results show that when proper waste collection and recycling is implemented, CRT TVs and monitors will have been eliminated within a decade (2028 being the marking year) meanwhile the trend for washing machine consumption continues to incline up until today.

Abstract The rapid development of technology has spurred competition among electronics manufacturers to innovate. The resulting electronic waste (e-waste) has potential hazards due to its composition. The prediction of e-waste generation is carried out using the Delay Model method, modified by applying end-of-life (EoL) value to the lifespan to adjust Indonesian society’s treatment of e-waste. The calculations show that the prediction of hazardous material from Indonesia’s household sector will reach 16,653.73 tonnes in 2040, while the non-household sector comes to 25,391.72 tonnes in 2040. The most e-product produced from the household sector is TV with 3,763.74 tonnes, while the non-household sector is also dominated by TV with 23,380.52 tonnes in 2040. The composition of materials obtained from e-waste, in general, is 1% hazardous materials, 31% ferrous metal, then 27% glass and plastic materials, 6% non-ferrous metals, and 8% other materials. Thus, the total generation of e-waste will reach 4,204,545.43 tonnes, and the hazardous components in e-products only reach 42,045.45 tonnes or about 1% of the total e-product generation. In the future, it is necessary to integrate and formalize the handling of e-waste from the informal sector, which has been developing into the formal sector. This research is expected to be used as a reference by the government to make regulations, plans, and strategies related to hazardous waste management to prevent harm to the environment and human health.

The data on the dynamics of e-waste generation in different countries are presented and modern methods of handling this type of waste are analyzed. The characteristics of the component composition of electronic waste are given. The problem of neutralization and disposal of mobile phone screens has been studied. An analysis of possible methods for extracting metals from electronic waste has been carried out, which has shown the promise of a biotechnological method based on the ability of the biomass of microscopic algae to selectively, under certain conditions, sorbs metals. Based on the analysis of the research results of domestic and foreign scientists presented in the literature the process of extracting indium from the screens of mobile phones using microscopic algae was simulated under laboratory conditions. When justifying the choice of indium as an extractable metal, two criteria were used: limited distribution in the earth's crust and the difficulty of obtaining from natural ores, as well as demand in various industries. In experimental studies, the parameters of the effective extraction of indium by the biosorption method have been determined.

Product Recycling

The significant environmental cost associated with management of products at the end-of-life has resulted in the emergence of ‘producer responsibility’ legislations to encourage increase in recovery and recycling practices. In the case of electrical and electronic equipment, one such legislation, namely the ‘Waste from Electrical and Electronic Equipment Directive’, requires manufacturers to assume financial and legal liability for recovery and recycling of their products at the end-of-life. The current recycling applications of electrical and electronic waste are often developed on ad hoc basis and mainly attributable to the hidden economic value within used products. However, owing to stricter regulations on end-of-life product recycling, it is now essential to evaluate the recycling costs and environmental benefits of reclaimed products and materials as well as the selection of appropriate recycling strategy. The present paper describes the initial investigation in the realization of a computer-aided recycling process planner for electrical and electronic products. The assertion made is that such a systematic approach to producing bespoke eco-efficient recycling process plans for individual products will significantly improve the value recovery from recycling activities.

Knowledge And Attitude

Electronic devices have become essential to our existence leading to an increase in the rate of electronic waste (E-waste) generation and  environmental degradation. This study evaluates the knowledge, attitude and prevailing practices of e-waste workers at the Owode-Orinin scrap market in Kosofe Local Government Area of Lagos Nigeria using 241 Questionnaires to obtain data which were analysed by Pearson correlation  coefficient. The knowledge of the respondents was limited to the financial and economic value attached to E-waste meanwhile the environmental and health impact of their occupation were not known, neglected or considered unimportant. A positive relationship was established between education, knowledge and attitude of the respondents. This indicates that increase in education brings about increase in the knowledge and results in positive attitude of the E-waste workers. The strong social tie found to exist among the E-waste workers can be leveraged upon for the transmission of the knowledge about the environmental health impact of their occupation so as to conduct their activities in the safest manner possible.

Reverse logistics is an item management activity that is no longer used by consumers or goods in the form of return from partners in the supply chain to be returned to the origin, because the product is unfunctional properly or the function of the item is not needed. Home appliances products within a certain period of time, these products must be replaced because they cannot technically function properly. The process of producing, using, and disposing of electronic products has an impact on the environment of the earth and the universe. If electronic waste is left without a policy to process it, there will be a buildup of electronic waste everywhere and will burden the environment. While this electronic product waste still contains economic value that can still be utilized. Therefore it is necessary to identify electronic waste handling activities, namely those that have material flow characteristics from the customer to the producer (reverse logistics), so as to provide added value.

The high population growth rate results in an increase in the volume of waste. So far, most people still view waste as useless waste, not as a resource that needs to be utilized. According to SNI 19-3964-1994, municipal solid waste generation is 2 – 2,5 Liters/person/day or 0,4 – 0,5 kg/person/day, small town waste generation is 1,5 – 2 Liters/person/day or 0,3 – 0,4 kg/person/day, the waste generation for large/ metroppolitan cities is greater that 3 Liters/person/day (Center for Resettlement Research an Developmen, 2010). With the reduce, reuse, recycle (3R) program, the amount of waste generation can be reduced. To implement 3R based waste management, the waste reduction process begins with waste sorting. Sorting handling activities according to the type and nature. Based in data from the Balikpapan City Environmental Service, the averange waste production from January 2018 to May 2018 reached 344,73 tons/day. The program for sorting and processing waste from sources is still limited, in Gunung Bahagia Village the success rate has only reached 60%. Waste sorting based on characteristics, the importance of providing understanding and application of waste sorting to the community as a waste producer. Waste sorting is the first step taken to reduce the level of waste in the TPA. Waste sorting should be carried out from waste produciing sources. Waste sorting is carried out based on waste characteristics. Garbage has the characteristics of being easily biogefradable or what is called organic waste, it takes a long tim (years, decades, hundreds of years) to decompose or what is called inorganic waste, waste of hazardous and toxic materials. By sorting waste based on cheracteristics, waste processing can run effectively and efficiently, has econimic value and environmental sustainability. Organic waste has economic value from processing in the form of compost. Inorganic waste has economic value, because this type of waste can be reused and recycled. For hazardous and toxic waste materials, the sorting can reduce environmentals pollution, considering that this type of waste is very easy to react.
