As the population grows there is an increase in wastage from our economic activities. Causing pollution on land, water, air, and on all other living things. India, being the second largest populous country in the world produces enormous organic and inorganic waste. While the household and agriculture waste may be used immediately after simple treatment, the waste generated from industries cannot be used as it is. If the industrial leftovers are effectively recycled or retreated by adopting suitable management techniques, then there will be no unwanted element in the environment. Rather, all nutrient elements if recycled, may enrich soil and other natural resources. Scientists and economists have found new technology to treat all waste as a source through recycling, conversion, source of energy, and land reclamation. Now, they have come to the conclusion that waste is a waste if untreated, but if it is modified in some other form, it is a potential resource and a wealth for our future. However, the only requirement is that it should be treated properly or taken care of. This paper examines some of the technology adopted by scientists, economists to use the waste as one of the potential resource either through knowledge or any other means for increasing productivity, maximising returns, and reducing pile up of unused waste. Successful case studies have been reviewed and analysed critically.

The growth of the population is related to urbanization, development, and industrialization. There found a strong correlation between population, industrialization, and waste production. The famous thermodynamics laws offer insights into the technological/marketing impact on waste production and energy conversion processes. The conventional methods such as land filling, combustion, gasification, incineration, etc. not enough to manage such a huge volume of waste. The non-segregation tendency, consumerism nature makes this waste management work problematic. The paper studies the natural efficiency in the waste management system and also the inability of traditional technology's to handle rapidly increasing waste volume. The plasma-based waste technology is similar to the natural waste management cycle, but with high volume capacity in a short duration. This also has a scope of waste to energy (WtE) conversion. Though plasma has high installation and maintenance costs, revenue generation from byproducts like syngas and slag will create it financially viable.

This paper reports the results of an extensive investigation on the waste management in Hong Kong abattoirs with the following objectives: (i) to identify the existing waste management practices in relation to sources and quantity of wastes generated, methods of storage and handling of wastes, any in-house treatment, and final disposal of wastes, (ii) to identify the problems of existing waste management practices, and (iii) to evaluate the future development. To obtain up-to-date data and reliable information, site visits were conducted and the management of the abattoirs were interviewed in detail about the operation and waste management practices. For each abattoir and one associated by-product plant, detailed material balances were established for liquid and solid wastes. Complete quantitative results on waste loads, water consumption and material/waste flows are presented. Operational problems regarding wastewater treatment, as well as waste reduction and potential for reuse or recycle of solid wastes are discussed in the context of Hong Kong. Finally, information on the proposed new slaughterhouse (design capacity 5000 pigs and 400 cattle daily) is provided which will include a novel underground wastewater treatment plant.

Current building management standards demand that construction waste management occurs in the planning phase. This paper presents the development of a plug-in as a BIM tool to predict waste generation. As a research strategy, the plug-in was applied to a single-family housing project, the respective construction wastes were predicted in the BIM technology and compared to the literature. Through waste generation indexes, some planning indicators were calculated. The identified wastes were automatically classified, and a management structure was designed. The study showed that the best results are obtained when the construction waste is estimated from Actual Built Volume instead of Apparent Constructed Volume like the traditional models uses. In conclusion, adopting a plug-in do predict construction waste has proved to be advantageous. A specific advantage of the proposed method is that the plug-in user may adopt their waste generation indexes according to the regional and the production team aspects. The adoption of a plug-in made the acquisition and processing of data fast and versatile.

In cities where a large geographical area of the city is densely populated, the process of waste collection is cumbersome, tiresome and expensive. Often, the burden of manually tracking and collecting of waste causes waste management companies enormous wasted effort and get them involved in tasks that are not necessary. No doubt, a digital interaction between waste management companies and targeted waste collection areas could ensure the process becomes fast, efficient and traceable as they become aware of the states of the wastes, aptly. It will considerably reduce any discrepancies that may occur due to the lack of information available during a particular time. Accordingly, this paper proposes a novel approach towards waste management combined with the internet of things to reduce the problems that would occur due to the accumulation of wastes and hence improvise waste collection/management process. Additionally, an innovative feature which generates revenue and creates business opportunities for waste management companies is introduced via advertisement solution based on network-attached storage technology.

This study aims to study the waste management process and recycling of municipal waste in Tehran. Currently, Kahrizak is the defined landfill area which collects the waste generated from 22 districts of Tehran. The organic wastes undergo to the windrow composting method in order to manage the partial of the waste generated in the city. Samples from the compost pile generated in Kahrizak were examined to evaluate its fertilizer value to be used further by the farmers. The results show that the obtained compost does not reach the acceptable quality to be used further in agriculture, due to lack of homogeneity, aeration and presence of heavy metals. Overall, it has been concluded that, due to the improper waste segregation and management prior to sending to landfill and presence of non-organic materials such as hazardous metals and medical wastes, causes difficulties in proper waste management, implementation and producing high quality compost. Based on this study the existence of stakeholders, society, economy and proper handling rules can effectively improve the waste management system in the country and leads to the sustainable green environment.

In order to improve the municipal solid waste management efficiency, smart management approaches have been proposed such as wireless sensor network architecture solution which includes the use of sensors to detect the garbage bin fill levels and vehicle route optimization techniques. Experimental results show that we can save up to 35% of the operational cost by improving the efficiency of solid waste management. In this thesis, a new low-cost architecture solution is proposed for improving the efficiency of municipal solid waste management without the use of sensors. Instead, a messaging application is used to ask the customers for pick up of garbage. Based on their reply, the prototype architecture uses a cluster-first route-second method that implements a clustering algorithm with truck capacity as the constraint and solves a travelling salesman algorithm in each cluster. The prototype architecture consists of a back-end server that implements sweep clustering algorithm for clustering the customers by their location and solves travelling salesman problem with dynamic programming method in each cluster, firebase realtime database and front-end using android application for the mobile. The experimental results show that the prototype system can adapt to the change in dataset size and truck capacity constraints. We have observed that with an increase in truck capacity constraint, the number of clusters formed for the data set decreases. Forward and backward sweep clustering methods have been compared where there is no significant difference in the results produced. The dataset has been generated manually due to unavailability of real data from various sources. As a future work, we need to test the prototype with the real data in order to produce more accurate results.

The novelty of this research is that it investigates an on-site solution for the treatment of restaurant waste using a microwave generated plasma for pyrolysis and gasification. The developed system has been used to treat waste from a city centre fast food restaurant. The system was designed with the aim of reducing the amount of waste being sent to landfill by approximately 94%. The waste is mostly food based but also includes paper waste such as napkins. It was separated into three categories: mixed food, paper and fries. Samples of the mixed food and paper waste were analysed for chemical composition and calorific value. A 2.45GHz magnetron was used to supply 1kW of microwave power to a plasma cavity that had an argon flow rate of 1.5 litre per minute. The design of the microwave plasma cavity was performed using the simulation software, COMSOL. The cavity consists of a tapered waveguide section that is shorted at one end to produce a stationary wave with a large electric field at the gas nozzle. The field is strong enough to produce a self-striking argon plasma when the power is applied. Nitrogen was used to keep the plasma cavity clear of smoke, vapours and other hot gas. The best nitrogen flow rates were found to be around 2 litres/minute, although 5 litres/minute was used in the test to avoid the CO sensor saturating. The combination of the argon and nitrogen was used to purge the gasifier of oxygen. The pressure inside the gasifier was held at 200mbar during the experiments. The resulting plasma jet was used to produce syngas from the waste samples inside a thermally insulated, steel-walled reactor. Temperature profiles were recorded to find the best gas flow rates. 10g samples of the three waste categories were tested in triplicate and the results are presented. Syngas production was recorded using a Quintox gas analyser that measured CO, CO2 and O2. The data was captured every 10s during testing using a PC running a custom-built LabVIEW program. This program was also used to set the microwave output power and record the reflected power and temperatures using National Instruments cDAQ modules with analogue to digital converters. The CO and H2 in syngas can be used as a fuel to offset the cost of running the plasma jet. The results reveal that it is possible to generate the syngas using waste food materials. This study has included an investigation of some of the parameters, including power and flow rates of argon and nitrogen, on the plasma created. Others effects were taken into consideration throughout the research such as the study of the sample moisture levels and the final reduction of mass after the experiment. The ashes produced by the tests were investigated using SEM/EDX analysis. These results are also presented and analysed.

With the transition to Industry 4.0, actors in many industries face challenges such as how to successfully implement technical solutions and retain competitiv eadvantages. In the smart waste management sector, many solutions have been presented in how to create effecient sensors but a practical way of comparing these solutions is non-existent. From research within Industrial Internet of Things (IIoT) and interviews with operators at Scania, we present a clear and effective way of comparing smart waste management sensors with regards to operational effectiveness. Along with this, we present a way to measure  fill volume of garbage containers using monocular depth estimation and compare this to using ultrasonic sensors. Our findings show that depth estimation with deep convolutional neural networks is viable as long as environmental conditions can be controlled, although, we have also found that ultrasonic sensors outperform depth estimation in many metrics and is the desired way of measuring fill level of containers in many applications. Despite this, the results of this research show promise in that depth estimation can be used in conjunction with object recognition models, leading to the obsolescence of ultrasonic sensors in more complex applications.
Med den tekniska omvandlingen till Industri 4.0, ledande aktörer i många branscher ställs inför utmaningar såsom hur de ska implementera tekniska lösningar och bibehålla konkurrenskraft. Inom området för smart avfallshantering har många tekniska lösningar presenterats som på ett effektivt sätt mäter soptunnenivåer men ett praktiskt sätt att jämföra dessa lösningar saknas. Från forskning inom Industrial Internet of Things (IIoT) och intervjuer med operatörer på Scania har vi tagit fram ett koncist och konkret sätt att jämföra dessa lösningar med avseende på operativ effektivitet. Tillsammans med detta har vi också tagit fram en djupestimeringsmodell som med hjälp av djupa konvolutionsneuronsnätverk kan mäta fyllnadsvolymen av soptunnor. Vi har visat i vår forskning att detta djupestimeringsnätverk är ett möjligt alternativ till andra sensorer. Vi jämför sedan detta system mot ultraljudssensorer och har funnit att ultraljudssensorerna presterar bättreän djupestimeringsmodellen på  flera av de centrala mätvärdena. Trots detta så drog vi slutsatsen att vår metod att mäta fyllnadsvolym av soptunnor med hjälp av djupestimering kan användas tillsammans med objektigenkänning i mer komplexa applikationer för att undvika användandet av enklare sensorer, så som ultraljud.

This research aims to propose an integrated method, which combines all the aspects required to reduce environmental impact from waste packaging and to increase knowledge on the best way to enhance reusable packaging. Through a review of the extant literature, a conceptual framework was designed of the most important dimensions to enhance reusable packaging amongst society and industries The main contributions in the research are the development of a Social Behaviour Aspect Model (SBAM) and the creation of reusable packaging attributes checklist. The SBAM can help industries focus on having high knowledge about reuse of packaging and to cooperate with communities to develop personal and social values and norms during the designing of reusable packaging. SBAM is the output from the first phase, which showed the importance of making an effort to develop packaging for consumers to reuse. The reusable packaging attributes checklist can provide a guideline for manufacturers/designers who intend to develop packaging sustainability performance through designing reusable packaging, and contribute to meet and interpret the reuse of packaging requirements and procedures. It also determines the environmental impact of reusable packaging attributes, which many industries are concerned about. The reusable packaging attributes checklist is the output from the second and third phases. The System Dynamic (SD) method was the approach used to determinate the interaction between social aspects and reusable packaging. The Normal Average, Codes and Coding and factor analysis with Principal Component Analysis (PCA) approaches were used to determine the reusable packaging attributes checklist. The last phase of the research was the conduction of a case study of a real company which needs to increase the amount of reusable packaging it uses and which seeks to reduce its environmental impact. All methods used in this research have both a quantitative and a qualitative nature. Data was collected by evaluation of consumers' responses and experts' experiences, as provided in the questionnaires. This research opens up opportunities for improving packaging and meeting sustainable profits and provides valuable information based on social, economic and environmental benefits of reusable packaging. The novelty of this research can help industries to investigate the most important areas for development within communities to enhance the use of reusable packaging and also facilitate the process-based change from one-way packaging to reusable packaging effectively with reduction of environmental impact.

Costa Rica is a small country located in Central America. It is known for its lush forests and a completely renewable electricity grid. However, this country has a highly deficiente waste management problem. The entire waste ends up in landfills, and no economic or energetical value is taken out of it. Furthermore, this system produces high amounts of greenhouse gases which are a problem for a country that is trying to decarbonize its economy. This thesis studies three different waste management technologies in an attempt to figure out which is the most suitable for San Jose, Costa Rica. The technologies studied are waste incineration, anaerobic digestion, and landfill gas capture. Each technology is assessed under three aspects: the amount of income each generates, the amount of electricity it produces, and the amount of greenhouse gases each emits. Once the calculations for total income, electricity, and electricity produced for each technology were done, anaerobic digestion seems to be the most suitable option for San Jose due to its low emission tally. However, alternative solutions must be further studied to treat the remaining waste not treated by this option. Furthermore, waste incineration is the technology with the potential to produce more electricity, and thus generate more income. The landfill gas capturing system diverts a significant amount of emissions from landfills. However, it generates low income and does not solve the landfill problem.

The amount of waste in the world increases every year due to an improved living standard andgrowing population. The problem is especially large in poor countries where the ability tohandle the waste is limited due to financial and management problems. If instead wastematerial is seen as a resource it can help reduce the amount of waste on landfill. Byincinerating waste and recover the energy it would also help reducing greenhouse gasemissions from landfill and give electric and thermal energy.Chisinau Municipality in the Republic of Moldova today lacks several important parts fora satisfying waste management. Today most of the waste generated in Chisinau municipalityends up at the municipality landfill. The current contract to use the landfill expires on the 31December 2010, if the municipality won’t be able to renew the contract they have to look forother ways to deal with the waste problem. As the dominating source for energy in Chisinau isimported natural gas, an effective way to reduce the use of gas for electricity and thermalenergy production would be to use waste material for incineration with energy recovery.Therefore, the goal with this thesis is to evaluate the possibility to extract energy from coincinerationof sewage sludge and waste material generated in Chisinau. To reach this goal thesituation in Chisinau where studied on site for two months, quantities and composition of thewaste material was investigated. Based on the data gathered on the waste, a suitabletechnology for the waste-to-energy (WTE) plant is proposed. The proposal is made based onthe assumption that a WTE plant would not be established until 2025.The result shows that the waste material in Chisinau can be used for co-incineration ofwaste and sludge. The calorific value of the waste material was determined to 7.87 MJ per kg.The suggested WTE plant has the total power of 138 MW, the result based on that all wastematerial available 2025 are incinerated. Annually this makes it possible to recover 1152 TJ(320 GWh) electric power and 2650 TJ (736 GWh) heat, based on 8000 operating hoursannually.Even if a WTE plant sounds like a good investment it is a long time before a plant couldoperational. Much is to be made in the waste management to have well-functioninginfrastructure that will work together with an incineration plant. Furthermore, the data used inthis study regarding the quantities is very uncertain and further studies in affected areas arenecessary before a WTE plant can be established.


Den totala mängden avfall i världen ökar varje år som följd av ökad folkmängd ochlevnadsstandard. Problemet är extra påtagligt i fattiga länder med begränsade ekonomiskaresurser för att ta hantera avfallet. Om avfallet istället skulle ses som en resurs skulle detkunna reducera andelen avfall som läggs på deponi. Genom att förbränna avfallet medenergiåtervinning skulle också växthusgaserna från deponering minska och samtidigt geelektrisk och termisk energi.Chisinau kommun i Republiken Moldavien saknar idag flera vitala delar iavfallshanteringen. Idag slutar den största delen av avfallet som produceras i Chisinaukommun på den kommunala deponin. Kontraktet för att använda deponin löper ut den sistadecember 2010, om Chisinau kommun inte tillåts förnya kontraktet är det nödvändigt att sesig om efter nya lösningar för avfallshanteringen. Eftersom den dominerande källan för energii Chisinau är importerad gas, skulle ett effektivt sätt att reducera gasanvändningen vid el ochtermisk energiproduktion att förbränna avfall med energiåtervinning.Av den orsaken är målet med studien att utvärdera möjligheterna att utnyttjasamförbränning med energiåtervinning av avfall och avloppsslam från Chisinau kommun. Föratt nå detta mål har den nuvarande situationen i Chisinau kommun studerats på plats under tvåmånaders tid, detta för att undersöka vilka mängder avfall som årligen produceras och huravfallets fraktionsfördelning ser ut. Baserat på de data som samlats in föreslogs en lämpligavfallsförbränningsanläggning. Förslaget är baserat på antagandet att enavfallsförbränningsanläggning inte är etablerad förrän tidigast 2025.Resultatet visar att det är möjligt att samförbränna avloppsslam och avfall i Chisinau. Detkalorimetriska värmevärdet för avfallet och slammet har bestämts till 7.87 MJ per kg. Det irapporten presenterade förslag på kraftvärmeverk för avfallsförbränning kommer att ha entotal effekt av 138 MW, resultatet är baserat på att allt tillgängligt kommunalt avfall 2025förbränns. Kraftvärmeverket beräknas årligen utvinna TJ (320 GWh) elektrisk energi och2650 TJ (736 GWh) termisk energi, beräknad på 8000 drifttimmar årligen.Även om en avfallsförbränningsanläggning låter som en god investering så ligger detlångt fram i tiden innan en sådan anläggning är möjlig att etablera. Först måste en brafungerande infrastruktur som fungerar tillsammans med avfallsförbränningsanläggningenupprättas. Vidare bör poängteras att de data som använts i denna studie gällandeavfallsmängder är ytterst osäkra och ytterligare studier inom området krävs innan enavfallsförbränningsanläggning kan etableras.

Inadequate waste management has become a global concern during the last decades due to an increasing population and economic growth. When a larger amount of people get access to new types of waste the potentially harmful waste streams are increasing in both cities and rural communities. The setting of this study has been a rural community called Linga Linga in southern Mozambique and has been conducted through a literature study, questionnaires, and interviews. Linga Linga is a village that has poor infrastructure, a lack of financial resources, and an overall low education level. The presence of the government is scarce, but the organization Project Vita has its base in the community and has started a few development projects in the village. The waste management in Linga Linga today is non-existent and the most common methods for waste disposal are burning or burying in the natural environment. In this study, the most important factors today and in the future waste management development of Linga Linga has been identified and analyzed. This has been done by using another village as a potential future situation and with the help of previous studies done in similar rural villages. To improve the situation and prevent future problems regarding waste it will be important for Linga Linga to focus on education, institutional change, and implementation of a waste system that meets local needs.
Bristfällig avfallshantering har blivit ett globalt problem under de senaste årtiondena på grund av populationsökning och ekonomisk tillväxt. När en större mängd människor får tillgång till nya typer av avfall så ökar de potentiella farliga flödet av avfall i både städer och på landsbygden. Denna studie har utförts i Sverige med utgångspunkt på landsbygden i södra Mozambique, i ett samhälle som heter Linga Linga. Studien har gjorts med hjälp av en litteraturstudie, frågeformulär och intervjuer. Linga Linga är en by med dålig infrastruktur, brist på finansiella tillgångar och en överlag låg utbildningsnivå. Närvaron av staten är sällsynt men organisationen Project Vita har sin bas i samhället och har startat flera utvecklingsprojekt i byn. Avfallshanteringen i Linga Linga idag är praktiskt taget obefintlig och de vanligaste sätten att göra sig av med avfall på är genom att bränna eller gräva ner det i naturen. I den här studien har de viktigaste faktorerna idag och i framtida utveckling av avfallshanteringen i Linga Linga identifierats och analyserats. Detta har gjorts genom att använda en annan by som ett potentiellt framtida scenario samt att inspiration hämtats från tidigare studier gjorda i liknande områden. För att förbättra situationen och förebygga framtida problem gällande avfall så kommer det att vara viktigt för Linga Linga att fokusera på utbildning, institutionell förändring och implementering av ett avfallssystem som möter lokala behov.

Communities around the globe are confronted by environmental challenges such as waste management. These challenges are further aggravated by factors such the increasing volumes of waste, landfills that are running out of capacity and scarcity of suitable land to construct new landfill sites. The National Waste Management Strategy requires participation from all members of society including households, businesses, community organisations, nongovernmental organisations, parastatals and the three spheres of government, to promote practices that minimise the volumes of waste generated. The purpose of the research was to assess and investigate the current waste management practices at the Cape Peninsula University of Technology (CPUT), and recommend a waste management system. The research employed a quantitative approach, where participants were asked to complete a survey questionnaire. A literature review was conducted on waste management at higher learning institutions, with particular focus on the contribution that a university can make in alleviating some of the adverse effects of waste management. The outcome of the review highlighted some of the opportunities and barriers that can either disrupt or augment the process of implementing a waste management system. The results from the research revealed that CPUT does not conform to the hierarchy of waste management, and there is no waste management policy in place. The effect of this is that the stakeholders were not satisfied with the lack of leadership on waste related challenges. By developing a policy, providing leadership, conducting awareness campaigns and prioritising environmental challenges such responsible management waste, could improve the image of the institution in the eyes if its stakeholders.

Includes bibliographical references.
What is electronic waste? Why is it considered a problem? What are the public health implications of its mishandling? The electronic industry, a sector that has experienced one of the highest growth rates of the last decade, has had a great success in growing the mass consumer market for personal computers, cell phones, and other types of personal electronic equipment. Supporting this incredible growth, the electric industry has also provided electric cells and battery systems to power all these devices. Unfortunately, personal computers as well as other electric and electronic equipment (EEE) become obsolete faster than ever. The mounting quantities of obsolete EEE and spent batteries represent a serious problem for the industrial sector, as well as for governments and citizens, not only because of the volumes being generated, but because of the hazardous materials and toxic metals, including lead, nickel, cadmium, mercury and chromium to mention some of the most important health wise and the gold, copper, aluminum, nickel, silver and palladium they contain. These contents also offer incentives for their collection and recovery. They need to be diverted from the waste stream reaching the sanitary landfills and in some instances incineration facilities, to reduce public exposure to these toxic substances and avoid the public health burdens they represent. What is the dimension of this problem in Mexico? Mexico has generated at least 6.3 million obsolete computers during the last decade, and by the end of 2006, 10 million additional personal computers will become obsolete. Not all of them will reach the municipal solid waste (MSW) stream the same year they become obsolete.
Hoarding by final users must be considered in designing any collection program. Even taking account of hoarding, almost 3 million computers will be available for collection in 2005 and 10 million computers will be available for collection by 2013. For spent cells and batteries in Mexico, the numbers are not very clear. The best estimate is that 450 million cells and batteries will be purchased annually (90 million rechargeable batteries and 148.5 million primary cells). At least 25% of them (hoarding of spent batteries has been estimated at about 75%) will be introduced into the municipal waste stream, some 37 million batteries every year. Taking into consideration Mexico's waste management infrastructure, what are the related Public Health effects of electronic waste? What are the risks associated with the final treatment options available? What can be done to reduce the E-Waste burden? Which collection and recycling mechanisms can be implemented in the Mexican context? The present work deals with these questions and introduces a proposed collection and recycling program to address Mexico's needs.

Population growth, increasing prosperity and changing consumer habits globally are increasing demand for consumer electronics. Further to this, rapid changes in technology, falling prices, increased affordability and consumer appetite for new products have exacerbated e-waste management challenges and seen millions of tons of electronic devices become obsolete. This rapid literature review collates evidence from academic, policy focussed and grey literature on the technical aspects e-waste value chains. The report should be read in conjunction with two earlier reports on e-waste management1. E-waste is any electrical or electronic equipment, including all components, subassemblies and consumables, which are part of the equipment at the time the equipment becomes waste. The exact treatment of Waste from Electrical and Electronic Equipment (WEEE) can vary enormously according to the category of WEEE and technology that is used. Electrical and electronic items contain a wide variety of materials. As a result of this complex mix of product types and materials, some of which are hazardous (including arsenic, cadmium, lead and mercury and certain flame retardants) multiple approaches to WEEE are required, each with specific technical guidelines. This report is structured as follows: Section two provides an introduction to the technical aspects of e-waste management, including a reflection on the challenges and complexities of managing a range of product types involving a range of components and pollutants. Section three provides an annotated bibliography of key readings that discuss elements of the technical aspects of managing e-waste. This bibliography includes readings on national guidelines, training manuals and technical notes produced by the Basel convention and courses. WEEE recycling can be a complex and multifaced process. In order to manage e-waste effectively, the following must be in place Legislative and regulatory frameworks Waste Prevention and minimisation guidelines Identification of waste mechanisms Sampling, analysis and monitoring expertise Handling, collection, packaging, labelling, transportation and storage guidelines Environmentally sound disposal guidelines Management is further complicated by the speed of technological advance with technologies becoming redundant much sooner than initially planned. Case studies show that the average actual lifetimes of certain electronic products are at least 2.3 years shorter than either their designed or desired lifetimes.

Population growth, increasing prosperity and changing consumer habits globally are increasing demand for consumer electronics. Further to this, rapid changes in technology, falling prices and consumer appetite for better products have exacerbated e-waste management challenges and seen millions of tons of electronic devices become obsolete. This rapid literature review collates evidence from academic, policy focussed and grey literature on e-waste management in Africa. This report provides an overview of constitutes e-waste, the environmental and health impacts of e-waste, of the barriers to effective e-waste management, the opportunities associated with effective e-waste management and of the limited literature available that estimate future volumes of e-waste. Africa generated a total of 2.9 million Mt of e-waste, or 2.5 kg per capita, the lowest regional rate in the world. Africa’s e-waste is the product of Local and imported Sources of Used Electronic and Electrical Equipment (UEEE). Challenges in e-waste management in Africa are exacerbated by a lack of awareness, environmental legislation and limited financial resources. Proper disposal of e-waste requires training and investment in recycling and management technology as improper processing can have severe environmental and health effects. In Africa, thirteen countries have been identified as having a national e-waste legislation/policy.. The main barriers to effective e-waste management include: Insufficient legislative frameworks and government agencies’ lack of capacity to enforce regulations, Infrastructure, Operating standards and transparency, illegal imports, Security, Data gaps, Trust, Informality and Costs. Aspirations associated with energy transition and net zero are laudable, products associated with these goals can become major contributors to the e-waste challenge. The necessary wind turbines, solar panels, electric car batteries, and other "green" technologies require vast amounts of resources. Further to this, at the end of their lifetime, they can pose environmental hazards. An example of e-waste associated with energy transitions can be gleaned from the solar power sector. Different types of solar power cells need to undergo different treatments (mechanical, thermal, chemical) depending on type to recover the valuable metals contained. Similar issues apply to waste associated with other energy transition technologies. Although e-waste contains toxic and hazardous metals such as barium and mercury among others, it also contains non-ferrous metals such as copper, aluminium and precious metals such as gold and copper, which if recycled could have a value exceeding 55 billion euros. There thus exists an opportunity to convert existing e-waste challenges into an economic opportunity.
