Indicators for national consumption-based accounting of chemicals

Increased chemical use is causing a growing number of environmental problems and chemical products are pervasive in societies within animal and crop-based agriculture, in industrial processes and in households. National environmental targets, as well as the global chemical-related goals in the 2030 Agenda, call for the monitoring of chemical use and emissions. The growing international trade of goods, where use and regulation of chemical inputs vary highly between countries, complicates measurements. This paper addresses these issues by deriving a set of indicators on chemical use and emissions and connect the global impacts to a country's total consumption, here using the case of Sweden. The indicators are based on a hybrid model combining the multi-regional input-output analysis database EXIOBASE with data from the Swedish System of Economic and Environmental Accounts together with a novel set of environmental extensions. A review of databases is conducted and discussed in relation to the driver-pressure-state-impact-response (DPSIR) framework for indicators. Five indicators are calculated, showing the chemical use and emissions connected to consumption, both within a country and abroad. The indicators are: use of hazardous chemical products, use of pesticides, use of antimicrobial veterinary medicines, emissions of hazardous substances, and of the potential toxicity of these emissions. The results show that the impact of Swedish consumption in terms of use and emissions of hazardous substances is largely taking place outside the Swedish borders. Only 10–24% of the pressure from Swedish consumption is shown to occur within Sweden's borders, depending on the indicator. The use of hazardous chemical products and veterinary medicines related to Swedish consumption primarily takes place in other EU countries, whereas the use of pesticides as well as reported emissions of pollutants occur mainly in countries outside the EU. The results highlight the need for improved international accounting of chemical flows, as well as for strengthened policy frameworks to address cross-border impacts of consumption of hazardous chemical products.

An eco-friendly approach for metals extraction using polymeric nanofibers modified with di-(2-ethylhexyl) phosphoric acid (DEHPA)

The aim of this work was to develop new materials employing polymeric nanofibers modified with an organic extractant for the extraction of metals. For this purpose, nylon-6 nanofibers were modified with di-(2-ethylhexyl) phosphoric acid (DEHPA) for use in the selective extraction of zinc and nickel. The best extraction efficiencies were 85.5% for Zn and 4.6% for Ni, achieved under the following conditions: pH 2, solid:liquid (S:L) ratio of 1:40, and contact time of 7.5 min. In the stripping, the best efficiencies were 85.9% for Zn and 90.1% for Ni, using a concentration of HCl of 0.5 M, S:L ratio of 1:10, and contact time of 5 min. The nanofibers were evaluated in terms of their stability and capacity for reuse, and it was found that there was no loss of the DEHPA extractant from the nanofibers, while the extraction efficiency remained almost constant. Regarding to environmental aspects of the new technology, the results confirm that nanofibers exhibit the same efficiency of conventional liquid-liquid extraction, without the disadvantage of the use of organic solvents. In this way, this new technology brings an enormous gain in environmental terms, since it drastically reduces the use of hazardous substances.

A consequences-based approach for the selection of relevant accident scenarios in emerging technologies

The rapid progress of innovative biorefinery technologies raises the issue of emerging risk and major accident hazard in biorefineries, as process safety aspects of such technologies are not developing at the same pace with respect to their dissemination and scale-up.To address such problem, in the present work a consequence-based approach was integrated in the framework of a consolidated QRA methodology (ARAMIS), formerly developed in the context of Seveso Directive in the process industries (mainly oil&gas). Among all the possible scenarios identified using ARAMIS, Relevant Accident Scenarios (RAS) were selected by calculating hazard distances using threshold values for the evaluation of damages on human target derived from existing regulations on the control of major accident hazards.The method has been described and used to quantify the risk associated to a biorefinery process: the conversion of lignocellulosic biomass materials to levulinic acid and gamma-valerolactone, where the use of hazardous substances and severe process conditions are required.Using the proposed approach allowed to reduce the number of scenarios to be retained for further analysis. The RAS resulted 1/3 of the scenarios initially identified, simplifying the rest of the risk assessment procedure.The integrated methodology enabled to depict a risk figure for the plant analysed which is not over-conservative, being beneficial during the risk management phase, when risk reduction measures have to be selected and implemented in order to achieve risk tolerance.

Greening offices: Willingness to pay for green-certified office spaces in Bengaluru, India

The rapidly growing construction sector in India has a large resource foot print but can offer a vast potential to mitigate and adapt to climate change. Greening the building sector is feasible through various policy measures and incentives to deal with recycling and waste treatment, reduction in energy use, emissions and the use of other hazardous substances, which have several public and private benefits. The objective of this study is to understand whether or not and by how much would the consumers be willing to pay for green buildings if the information asymmetry is reduced by information provisions of benefits from green buildings. This paper uses a choice experiment to evaluate the firms’ willingness to pay for green-certified office spaces in the Indian city of Bengaluru. The study relied on primary survey data drawn from around 115 firms working in rented office spaces in Bengaluru, who were asked to choose between status quo and different levels of green certification. The Tobit model was used for estimation, and the results show that firms value private benefits like reduction in electricity and water bills, water and waste recycling significantly. The willingness to pay of firms is negatively related to rent of the office space and positively related to annual turnover of the firm and prior knowledge on the green building certification.

Fen peat in environmentally friendly technologies

Using peat as an energy source is currently incompatible with Environmental Policy Strategy of Latvia and 2030 Climate and Energy Package of European Union. The European Commission is looking at cost-efficient ways to make European economy more climate-friendly and less energy consuming. Although, fen peat alongside raised bog peat is categorized as fossil fuel, it is not traditionally used as fuel or growth substrate or for any other significant purposes in reasonable amounts. Large areas of fens are neglected where fen peat is slowly mineralizing and emitting greenhouse gases, such as carbon dioxide and methane, that are ones of the main triggers for the Climate Change. Thus, to reduce greenhouse gas emissions and for reasonable and extensive use of natural resources, it is important to find new fields for use of fen peat. One of many fields where fen peat has high potential is environmental technology, allowing minimizing the use and generation of hazardous substances or pollutants. Moreover, use of fen peat can be as an alternative technological approach to reduce consumption of nonrenewable resources. However, in the generation and evaluation of new or alternative solutions, it is important that all available information on the potentially new product or its source is set out as clearly and as economically as possible. Thus, in this study we evaluated some of the most significant fen peat properties for consideration of its use in green technologies. Our study shows on wide range of possibilities where fen peat due to its properties has high application potential. Fen peat has a high potential in fields from agriculture and horticulture to pharmacology. Initiation of industrial fen peat extraction in excavated raised bogs and fen peat layer removal from agricultural lands can limit peat mineralization and reduce annual greenhouse gas emissions. Fen peat extraction can limit the need for peat excavation in intact mires and promote reasonable extraction of local natural resources.

Indonesian Teachers’ Perceptions on Green Chemistry Principles: a Case Study of a Chemical Analyst Vocational School

This study aims to describe the teachers’ perception of Green Chemistry, an area of chemistry that focuses on the design of products and processes that minimize the use and generation of hazardous substances. The description of Green Chemistry is based on the teachers’ perception of a Green Chemistry paradigm and how to integrate this perception into the chemistry learning process for their students. The perception and integration of Green Chemistry to achieve sustainable development in the field of chemistry needs to be promoted, especially among educators for spreading to their students. Data were collected by distributing questionnaires to 35 teachers in a Chemical Analyst Vocational School, Makassar, Indonesia. The questionnaire was based on the indicators related to the principles of Green Chemistry including prevention, economic atom, chemical synthesis safe, designing safer chemicals, solvents and compounds safe aides, design for energy efficiency, use of raw materials renewable, stages reduction reactions, use of catalysis, material design decomposition, instantaneous analysis for pollution prevention and chemical which are naturally more secure to prevent accidents. Data were analyzed descriptively to determine the percentage of teachers’ perceptions of green chemistry in learning. The results showed that, in general, the majority (97.14%) of teachers at this Indonesian school reported knowledge of Green Chemistry but only 32.30 % were aware of the concept of Green Chemistry. Furthermore, 47.42% of the teachers think that green chemistry does not need to be put into learning curriculum and 31.38% believe need to be included in the learning process. These finding demonstrate that the concept of Green Chemistry has not been socialized among teachers of Chemical Analyst Vocational School of Makassar. For this reason, there is a need for developing a learning model in chemistry teaching that responds to our vision for a sustainable future.

Capillary electrophoresis-driven synthesis of water-soluble CdTe quantum dots in nanoliter scale

‘Green nanotechnology’ is a term used for the design of nanomaterials and processes that reduce or eliminate the use and/or generation of hazardous substances. In this paper, a capillary electrophoresis (CE)-driven synthesis of CdTe quantum dots (QDs) and their subsequent conjugation with a metal-binding protein metallothionein (isofom MT1) is reported. Even though the toxic materials (cadmium and potassium borohydride) were used for synthesis, the proposed method can be labeled as ‘environmentally friendly’ because the whole process (synthesis of QDs and MT1 conjugation) was carried out under mild conditions: ultra-low volume (nanoliter scale), relatively low temperature (50 °C), atmospheric pressure, and completed in a short time (under 90 s). Prepared QDs were also characterized by classical fluorescence spectroscopy and transmission electron microscopy. This study opens up new possibilities for the utilization of classical CE in the synthesis of nanoparticles and on-line labeling of biomolecules in the nanoliter scale in short period of time.

Heavy Metal on a Tungsten Basis With a High Radiation Absorption Capacity Is an Ecological Alternative to Toxic Lead

EU Directive 2011/65/EU (Restriction of Hazardous Substances 2) regulates the use of certain hazardous substances in electrical and electronic equipment. Lead is ranked at the top of the list, even higher than mercury and cadmium. The heavy metal used as radiation shielding or for anti-scatter grids due to its high atomic mass is highly toxic and does not break down easily, which is why a weight proportion of only 0.1 percent is permitted in new electronic and electric equipment. It also has a low melting point of just 327°C, constituting an additional hazard in case of fire. The Bavarian company Wolfram Industrie offers an innovative, more environmentally friendly alternative with Triamet, a heavy metal alloy on a tungsten basis: thanks to its specific high density and the resulting radiation absorption capacity, the dimensionally stable product that is available in both an iron-nickel and a copper-nickel binder phase even shields against gamma radiation. While tungsten is normally difficult to process, it can be shaped into blanks using a powder-metallurgical process in this form. Subsequently these blanks can be processed further with little effort.

Relevance of the automated systems of environmental monitoring in the implementation of the best available technologies

The current state of the environment causes increasing concerns. At the same time, the tasks of economic development require expansion of industrial production, which in turn increases the burden on the environment. The solution to this contradiction is seen in using the best available technologies (BAT) as an economically more effective alternative to “green” technologies. Since the best available technologies do not involve the abandonment of the use of hazardous process substances, environmental monitoring systems that show the level of environmental contamination from them should be the most important concomitant element of these technologies. Solid-state chemical sensors can be used as the basis of such systems. To achieve high technical efficiency, the systems must be automatic or at least automated that will increase the level of public confidence in their work.

Green chemistry with process intensification for sustainable biodiesel production

Biodiesel as a renewable fuel has the potential to replace non-renewable fossil fuels and associated environmental pollution. The most commonly used method in biodiesel production is transesterification of virgin and used oil feedstock. However, the chemical reaction (transesterification) does not proceed spontaneously, which means excess reactants are required to move the reaction to completion. The biodiesel reaction efficiency can be improved by incorporating green chemistry principles and process intensification effects. Green chemistry principles can be used to design chemical products and processes that reduce or eliminate the use and generation of hazardous substances. Microwave- and ultrasound-enhanced biodiesel synthesis can improve the reaction efficiency due to higher product recovery, low by-product formation, and reduced energy consumption. In addition, utilization of green metrics such as E-factor, atom economy (utilization), mass intensity or mass productivity, and reaction mass efficiency can help design safer and highly efficient biodiesel synthesis. Green chemistry principles have been analyzed for other processes in greater details, but they are rarely discussed in the context of biodiesel production. Process intensification by microwave- and ultrasound-mediated biodiesel production was never discussed from the perspective of green chemistry and sustainable process development. This research review article discusses the role of green chemistry and process intensification in biodiesel production followed by specific examples and illustrations on green metrics of microwave- and ultrasound-enhanced biodiesel synthesis and the effect of catalysts and solvents including discussions on reaction kinetics and activation energy in detail for the first time in the literature.

Red tea leaves infusion as a reducing and stabilizing agent in silver nanoparticles synthesis

Due to the unique properties of silver nanoparticles there is growing interest in their applications. Current trends in nanotechnology are focused on developing a new technique to synthesize nanoparticles using biological methods associated with the use of plant extracts, fungi, bacteria or essential oils. These methods are a promising alternative to conventional approaches which can minimize the use of hazardous substances. The silver nanoparticles synthesis using red tea infusion as a reducing and stabilizing agent and their characteristics have been described. Total antioxidant capacity using DPPH radical and total content of phenolic compounds by Folin–Ciocalteau method were measured in tea infusion. Synthesis of silver nanoparticles was carried out using chemical reduction at various temperatures. Furthermore, the effect of tea infusion volume added to reaction mixture on nanoparticles’ properties was investigated. Finally, nanosilver suspensions were characterized by UV–vis spectrophotometer, dynamic light scattering (DLS) scanning electron microscope (SEM) and transmission electron microscope (TEM). Moreover, phytotoxicity of silver nanoparticles was determined using Phytotestkit microbiotest.

RESPONSIBILITY FOR THE TRANSPORTATION, STORAGE AND CIRCULATION OF HAZARDOUS MATERIALS

The problems of environmental protection have attracted the attention of of natural and biological sciences researchers for a long time, but the jurisprudence has been relatively late in the modern era. Take note of the legal problems posed by threats to the environment. On the environmental level, the problem of environmental pollution has become one of the most important problems affecting humans in modern times because of its harmful effects on both living and non-living organisms. At the international level, the State asks about the damage caused by environmental pollution to the international community, which is based on a set of legal rules that find their main source in international conventions, general principles of law and international judicial decisions in the field of environmental protection, and in the field of determining international liability for environmental pollution damage. From the legal point of view, the classification in Egypt according to Law 4/1994 and its amendments and its executive regulations is limited in light of the emergence of the international codes and the global guidelines in the field of hazardous materials which are comprehensive for all types of hazardous materials and capable of absorbing new ones. Therefore, the current study aims at clarifying all responsibility related to the transport, storage and handling of hazardous materials. The problem of the study is to know the adequacy and adequacy of Egyptian environmental law to classify hazardous substances and wastes and to appoint the concerned body and its responsibility for these materials and compensation for damages resulting from such wastes. Based on the problem of the study, the researchers in this study relied on the combination of the inductive method and the method of analyzing the results. The researchers conducted personal interviews with the officials in the [Holding Company for Maritime Transport and Container Handling in Damietta Port - Civil Protection Department in Damietta Port - Department of Safety and Occupational Health - the competent Environmental Affairs Agency (observer) Transport, storage and storage of hazardous materials. The results of the study that it is necessary to deepen the cooperation between the management of hazardous materials at the port and all security authorities inside and outside the port. As for the rules of liability resulting from the sources of environmental pollution, it is deficient and ambiguous, and in the end requires a radical development in line with contemporary global developments and in accordance with the era of the environment. It can not be denied that the civil liability regime in its free status continues to play an effective role in protecting the environment in its various dimensions. The need to include laws and ministerial decrees on the protection of the environment to the provisions of international laws and norms concerning the protection of the environment from the hazards of hazardous materials, taking into account the continuous raising of public awareness of the dangers and controls of the use of hazardous substances on the local clock. This is to expand the citizen's information base on the rules of safety and civil protection with the signs of dangerous goods. The present study recommends that citizens should be notified of the signs of dangerous goods and how they should be selected according to the classification prepared for this purpose. And the work of a comprehensive system of linking between similar departments in ports similar to cooperation and exchange of experiences at the level of the Egyptian country. Public awareness programs must be activated and school curricula, for example, should be implemented to preserve the environment and make it always green and to activate the role of environmental laws.

Effect of the Use of Pulse Plating Techniques in Electrodeposited Sn-Cucoatings for Pb-Free, Environmentally-Friendly Applications

The electrodeposition of lead containing alloys have found many industrial applications including electronics and other applications. However, lead is very harmful to health and the environment and the Restriction of Hazardous Substances Directive (RoHS) has been in force in Europe since 2003 restricting the use of certain hazardous substances (e.g. lead, cadmium, mercury etc.) in electrical and electronic equipment and this is likely to be extended to other industrial sectors. For this reason there is intensive research to find alternatives to lead alloys and one favourable candidate is Sn-Cu. This paper will describe a study carried out to obtain a deeper understanding of some of the factors affecting Sn-Cu electroplating. Experimental work, by means of Hull Cell tests, ultrasonic agitation and pulse plating, has been undertaken to understand the effect of these factors on the properties of the Sn-Cu coatings. A number of advanced analytical techniques, including scanning electron microscope (SEM), energy dispersive x-ray spectroscopy (EDS) and white light scanning interferometry (WLS), have been used to evaluate the characteristics of the Sn-Cu coatings, in terms of their surface morphology, chemical composition and microstructure. Our experimental results showed that pulse plating techniques combined with high speed magnetic stirring during deposition had a strong effect on the characteristics of the Sn-Cu electrodeposits and aslo Sn whiskers developing from the deposit.

Studying Newly Synthesized and Developed 4-Hydroxy-3-Methoxybenzaldehyde Schiff Bases by UV Spectrophotometry and High Performance Liquid Chromatography

Green synthesis is the design of chemical products and processes that reduces or eliminates the use and generation of hazardous substances. Schiff bases of 4-hydroxy-3- methoxybenzaldehyde (vanillin) were prepared using various aromatic amines and base catalyst in the presence of aqueous media. High performance liquid chromatography (HPLC) and ultraviolet (UV) spectrophotometry methods were developed for qualitative study of the synthesized 4-hydroxy-3- methoxybenzaldehyde Schiff bases. HPLC was carried out by reversed phase on a C18 column with a mobile phase composed of acetonitrile and 0.5% triethyl amine (pH 4.5 adjusted with orthophosphoric acid (60:40, v/v)). UV measurements were performed at λmax 286 nm for compound V1 ((E)-4-(4-hydroxy-3-methoxybenzylideneamino)benzoic acid), λmax 336 nm for compound V2 ((E)-4-(4-hydroxy-3-methoxybenzylideneamino)phenol), and λmax 320 nm for compound V3 ((2-methoxy-4-(E)-(phenylimino)methyl)phenol). Both the HPLC and UV methods showed good reproducibility and precision and were successfully applied to study 4-hydroxy-3- methoxybenzaldehyde derivatives. The standard de-viations of relative peak area and retention times for 4-hydroxy-3-methoxybenzaldehyde derivatives were within 2% indicating the suitability of the system. The proposed economical methods can be applied for rou-tine analysis of 4-hydroxy-3-methoxybenzaldehyde derivatives of any type.

The present work mainly focuses on the development of an eco-friendly corrosion inhibitor (phosphorylated chitin) which enables us to minimize the use of hazardous substances as corrosion inhibitors.

Diastase induced green synthesis of bilayered reduced graphene oxide and its decoration with gold nanoparticles

In this paper, we report an enzyme dependent, green one-pot deoxygenation cum decoration method to synthesize diastase-conjugated reduced graphene oxide (DRG) nanosheets, DRG/gold nanoparticles (DRG/Au) composite. The DRG synthesis was completed in 7h under heating at 90°C on water bath. Selected area electron diffraction (SAED) and Atomic force microscopy (AFM) study has revealed the formation of bilayered reduced graphene oxide sheets. Transmission electron microscopy (TEM) images of DRG/Au composite have shown the uniform decoration of gold nanoparticles (AuNPs) onto the DRG nanosheet surface. Fourier transform infrared spectroscopy (FTIR) and Raman results additionally have shown the functionalization of enzyme molecules onto the DRG nanosheet surface after reduction making it as an effective platform towards the efficient binding of gold nanoparticles. In vitro cytotoxicity studies by MTT assay on A549 and HCT116 cell lines exhibited that the cytotoxicity of the prepared graphene oxide (GO), DRG and DRG/Au is dose dependant. These results have shown that this synthetic method is effective for the production of large scale graphene in a low cost, simple and green method. Since this process avoids the use of hazardous and toxic substances, the produced DRG/Au composites are likely to offer various potential applications in biology and medicine.

The United Kingdom Ministry of Defence and the European Union's electrical and electronic equipment directives

The growth of the generation of Electrical and Electronic Equipment (EEE), and the use of hazardous substances in the production of these items, has required legislation to minimise the harm to the environment that their existing use, ultimate disposal and continued growth of the sector may pose. The European Union (EU) started to tackle this problem with the passing of two Directives in 2002, which focused on restricting the use of hazardous substances (RoHS - 2002/95/EC) and organising the recycling or disposal of discarded electronic and electrical equipment (WEEE - 2002/96/EC). These Directives have been recently recast and their scope widened; however, one exception to them remains items specifically designed for defence and military purposes. This paper looks at how and why these European Directives were passed, the impact they have had on defence in the United Kingdom (UK) up to the present moment, what impact the further extension of those directives might have on UK defence policy and how the UK Ministry of Defence (MOD) has begun to prepare for any extension, including the use of alternative products from the commercial market, and substituting less harmful materials. The paper reviews the information available to carry out future decision making and what level of decision making it can support. Where the data is insufficient, it makes recommendations on actions to take for improvement.

In addition, common difficulties of lab safety act applicable organizations are overlapping and comprehensive application of legal requirements. Conclusion: There is a need for laboratory safety professional organizations. Also, the high frequency of use of hazardous substances in the high-risk, such as the chemical field must be strengthened the laboratory safety management. In addition, it is needed to minimize the problems of the research organizations through close cooperation between related ministries and government support policy such as professional development program. Application: The result of this analysis might help to present a differentiated safety management policy and advanced safety management system in laboratory.

Engineering a more sustainable world through catalysis and green chemistry.

The grand challenge facing the chemical and allied industries in the twenty-first century is the transition to greener, more sustainable manufacturing processes that efficiently use raw materials, eliminate waste and avoid the use of toxic and hazardous materials. It requires a paradigm shift from traditional concepts of process efficiency, focusing on chemical yield, to one that assigns economic value to replacing fossil resources with renewable raw materials, eliminating waste and avoiding the use of toxic and/or hazardous substances. The need for a greening of chemicals manufacture is readily apparent from a consideration of the amounts of waste generated per kilogram of product (the E factors) in various segments of the chemical industry. A primary source of this waste is the use of antiquated 'stoichiometric' technologies and a major challenge is to develop green, catalytic alternatives. Another grand challenge for the twenty-first century, driven by the pressing need for climate change mitigation, is the transition from an unsustainable economy based on fossil resources--oil, coal and natural gas--to a sustainable one based on renewable biomass. In this context, the valorization of waste biomass, which is currently incinerated or goes to landfill, is particularly attractive. The bio-based economy involves cross-disciplinary research at the interface of biotechnology and chemical engineering, focusing on the development of green, chemo- and biocatalytic technologies for waste biomass conversion to biofuels, chemicals and bio-based materials. Biocatalysis has many benefits to offer in this respect. The catalyst is derived from renewable biomass and is biodegradable. Processes are performed under mild conditions and generally produce less waste and are more energy efficient than conventional ones. Thanks to modern advances in biotechnology 'tailor-made' enzymes can be economically produced on a large scale. However, for economic viability it is generally necessary to recover and re-use the enzyme and this can be achieved by immobilization, e.g. as solid cross-linked enzyme aggregates (CLEAs), enabling separation by filtration or centrifugation. A recent advance is the use of 'smart', magnetic CLEAs, which can be separated magnetically from reaction mixtures containing suspensions of solids; truly an example of cross-disciplinary research at the interface of physical and life sciences, which is particularly relevant to biomass conversion processes.

Beneficial Use Practice of e-wastes in Republic of Korea

The EPR system, Eco-Assurance System, and the Allbaro system were examined as the regulation of E-wastes in this study And beneficial use practice of E-wastes in Korea was introduced to improve recycling activities including collection system and recovery center with facilities In order to improve the recycling of waste in Korea (Republic of), the act on the promotion of saving and recycling of resources was activated in 1992. Under the act, waste charges and waste deposit fee system were operated for several products from industries to promote recycling measurement. Due to the abolition of waste deposit system in 2002, extended producer responsibility (EPR) system was introduced in 20003 by the amendment of recycling law Since early 2004, the Ministry of Environment of Korea has carried out a feasibility study to introduce an. “Eco-Assurance System (The ECOAS)” which would restrict the use of hazardous substances in electrical and electronic equipment and promote recycling of E-wastes by applying a systemic management for life cycle analysis from cradle to grave. On January 2008, the Eco-Assurance Committee System in Korea has been implemented under the Act on the Resource. Circulation of Electrical and Electronic Equipment and Vehicles for resource circulation and environmental conservation in a joint legislation by the Ministry of Environment, the Ministry of Knowledge & Economy, and the Ministry of Land, Transport and Maritime Affairs According to the ECOAS in Korea, 5 product groups and 27 items of WEEE including refrigerator, personal computer, electric oven, audio, and mobile phone are controlled to intensify the recycling capacity in electronic industries Beneficial use practice of recycling E-Waste in Korea were examined to improve recycling activities including collection system, recovery center with facilities by the information of E-Waste generation and recycling, policy and regulations of E-Waste Even though total generation of E-wastes was almost constant recently, the generation trend of TV, refrigerator and washing machine was very increased because those products was used in household more than 2 times for past 10 years Also, recycling rates of those E-wastes will be increased because recycling technologies have been improved and those E-wastes were readily decomposed by heavy parts.
