Plastic Wastes and Role of EPR

In just a few decades plastics have become omnipresent in our society. But, unfortunately, the consequences of their use last far beyond their useful lifetime. Everyone is aware of their overwhelming dispersion in our landscapes. The situation in the oceans is not better [1]. As a reaction, a few thoughts spring to my mind.

First of all, it is clear that the industry is assuming very little responsibility, and that Public Administrations are complicit with this. Extended producer responsibility (abbreviated as EPR) only affects –and only partially– those plastics used as light packaging, in vehicles, in tyres or as part of electric and electronic equipment, not any of the others. Also, recycling levels are not sufficiently high, as a result of poor separate collection systems and inefficient treatment facilities. As a consequence, society has to face not only the problems created by those materials which are not recycled, but also has to assume a high share of the costs of managing them as waste.

Secondly, it illustrates the importance of the quality of the materials that we aim to recycle, and thus the importance of separate waste collection; for all materials, but particularly for biowaste. Although most composting and anaerobic digestion facilities have the capacity to separate some of the impurities (of which around 40% can be plastics), this separation is far from perfect. Two recent studies confirm that the quality of compost is influenced by the presence of impurities in biowaste [2] and that, in turn, the presence of impurities is influenced by several factors [3], among which particularly the type of separate collection scheme, door to door separate collection models being those presenting better results.

Thirdly, it makes clear the urgency to adopt measures that address the root of the problem. High quality separate collection and sound waste treatment are necessary, and allow enormous room for improvement, but they are end-of-pipe solutions. It is also important to promote greener consumption patterns through environmental awareness campaigns, but this is not enough either. We have to address the problem where it is created. And this requires measures of higher impact, such as taxes on certain products (e.g. disposable ones) or on certain materials, compulsory consideration of eco-design criteria, generalisation of the extended producer responsibility or prohibition of certain plastics (e.g. oxo-degradable ones) or of certain uses (e.g. microplastic beads in cosmetics). One can think that these measures are a bit too hard, but honestly, after wandering around beaches and mountains, and finding plastics absolutely everywhere, I am bit disappointed with the outcome of soft solutions.

On 16th January 2018 the European Strategy for Plastics in a Circular Economy was adopted [4]. A number of measures will need to be applied by the European Union (listed in Annex I of the Strategy), by Member States and by the industry (Annex II), but also by Regional Governments and Local Authorities. No doubt that implementing the Strategy will bring about significant advances, but only time will say if it is sufficient to address the huge challenge we face.

The European Union has also recently adopted the much-awaited Directive 2019/904 of the European Parliament and of the Council of 5 June 2019 on the reduction of the impact of certain plastic products on the environment [5], which introduces several bans and restrictions on different uses and materials. This is indeed a huge step, which needs to be followed by others, both in Europe, but also elsewhere, as this is truly a global challenge.

Why Going Green is the Best Thing You Can Do for Your Community

As we go about our daily lives, it’s always a good idea to think about how we can contribute to the community we belong to in tangible and appreciable ways. Improving our communities from the inside not only allows us to make things easier and more convenient for ourselves, but also for the people we meet and rely upon in our day-to-day. Besides this, it also helps us think of other people’s needs rather than just our own—an essential need if we’re to live happy and productive lives. One of the best ways of improving our communities is, of course, going green: the act of adopting an environmentally-friendly lifestyle. This means taking active steps to minimize our carbon footprint and reducing waste.

It doesn’t have to start out big—we can start with the smaller things, and work our way up from there. Instead of buying new printer ink cartridges, for example, we can try using compatible ink cartridges instead. These are ink cartridges that are made the same way as new printer ink cartridges, but cost way less to make than branded ones. Instead of throwing away our old or obsolete electronics and electrical goods, we can look into getting them repaired. Another example of that is to refurbish old drones instead of buying new.

By taking up these eco-friendly practices, our communities will become cleaner, more energy-efficient, and much healthier places to live in, alongside other very practical and tangible benefits that everyone will appreciate.

Not convinced? Well, hopefully listing out those benefits in full below will convince you. Read on as we go through all the biggest reasons why going green is the best thing you can do for your community.

A healthier community

Enacting green and eco-friendly practices in your community will have the immediate effect of making it healthier for the individuals who live in it, enabling them to live longer, happier, and more productive lives. This can be considered as the most important benefit, seeing as we can tie so many health conditions and diseases to having an environmentally-negligent lifestyle. By going green, you can avoid these potential risks from taking hold in your community.

For example, recycling and minimizing trash or garbage helps makes your immediate surroundings cleaner and more attractive to look at. This causes disease-carrying pests such as insects and rodents to be driven away from your community, which then results in less people catching those diseases.

Another example is having the vehicles in your community switch to more eco-friendly fuel types will result in cleaner and healthier air, as well as reduce the chances of children and the elderly from getting respiratory diseases. Many companies like popgear use recycled material in their clothing. These and a whole lot more are attainable by going green.

Savings on utility bills and other expenses

One of the main tenets of going green is to be conservative when it comes to the usage of utilities, such as electricity, gas, water, and so on. It goes without saying that using too much of these obviously strains the environment.

For example, the excessive and unnecessary use of electricity when it’s clearly not needed increases the power demand from power plants, which in turn increases the amount of fuel being used to supply that energy. This uses up our remaining fossil fuels at an alarming rate, while also depositing more pollutants into the atmosphere and environment. The same goes for gas and other utilities.

By being smarter and more conscious about using these precious resources in our homes, we can reduce the impact we have on the environment by quite a large degree. It will help ease the strain our environment is currently experiencing in providing us these resources and ensure that they don’t run out as quickly as they would have if we continued being unnecessarily wasteful with our usage.

Besides this, conserving energy and resources also helps us save on our utility bills. Obviously, the less power, water, and gas we use in our day-to-day, the less we’ll be charged when our monthly bills come in. Up to 20% of expanses per household, according to the US Environmental Protection Agency, are saved, especially if we adopt changes such as using solar panels rather than relying on our electrical grid. This is a huge chunk of money no matter how you slice it!

Durable and stronger homes and and structures

Let’s not mince words about it: eco-friendly and environmentally-conscious “green” products are more expensive than the brands that have an easier time fitting into our budget. However, we must consider that the former is also much more durable than the latter, which will inevitably result in a lot of savings in the long run.

This can be seen the most in construction building materials, especially those involved in the building and repair of homes. For example, recycled decking, which is made from recycled plastic and wooden fibers, have been tested to last five times longer than traditional decking.

Bamboo, a self-sustaining perennial grass that can grow up to three feet in 24 hours, is lighter than most building materials and yet has greater compressive strength than brick and concrete. The best part about it is that it grows faster than it can be harvested, meaning that there’s no danger of running out of it anytime soon, no matter how extensively it’s used.

By creating your community’s homes and structures using these eco-friendly materials, you can help save the environment while also ensuring that the homes and shelters will last for as long as they’re needed.

A self-sufficient community

It’s a fact of life that we have to rely on big companies to get us the modern conveniences and essentials we need to get through the day. However, by going green, we can help reduce our reliance on them and become more independent in our lives.

For example, taking the initiative to install solar panels in every home in your community will allow it to become less dependent on the power that companies provide you with electricity. With enough time, your community will be generating enough excess power that the same company will be paying you for that excess. There’s also the fact that if something goes wrong with the power plant, your community won’t be subjected to the same annoying and disruptive blackout that other surrounding neighborhoods will be, as you’ll have enough solar power to last you the entire time.


Let’s say you’re not quite at that level yet, in terms of going green. How about supporting your local markets rather than your nearby supermarket? By doing so, you ensure that the food-growing sector of your community continues to earn a living while also retaining the ability to keep growing natural and organic produce. Doing so also cuts down on harmful emissions, as you won’t have to travel by car just to get the fresh food you need. Your community retains its independence while helping the environment.


There are many ways to improve one’s community from the inside, with one of the major and more effective ones being able to adopt eco-friendly and environmentally-conscious practices. By doing so, not only does the community benefit hugely in the end in terms of health, sustainability, and independence from big companies, but the environment as well.

Dealing with Household Hazardous Wastes

Household Hazardous Waste (HHW) are leftover household products that contain corrosive, toxic, ignitable, or reactive ingredients such as paints, cleaners, oils, batteries, pesticides etc. HHW contain potentially hazardous ingredients and require special care and safe disposal. 


A typical home can contain a vast array of household hazardous wastes used for cleaning, painting, beautifying, lubricating and disinfecting the house, yard, workshop and garage. The chemical-based household products from a single home may seem insignificant; but, when millions of homes use similar products, handling, storing and disposing them improperly may have the combined impact and becomes a major problem.

The health and safety of our families, neighborhoods and environment is threatened when HHW is stored or disposed of improperly. These products should not be put in the garbage bins or disposed in the storm drains or burned, as they pose a threat to human health and the environment. Thousands of consumer products are hazardous. The general categories are:

  • Automotive products: Gasoline, motor oil, antifreeze, windshield wiper fluid, car wax and cleaners, lead-acid batteries, brake fluid, transmission fluid etc.
  • Home improvement products: Paint, varnish, stain, paint thinner, paint stripper, caulk, adhesives etc.
  • Pesticides: Insecticide and insect repellent, weed killer, rat and mouse poison, pet spray and dip, wood preservative etc.
  • Household cleaners: Furniture polish and wax, drain opener, oven cleaner, tub and tile cleaner, toilet bowl cleaner, spot remover, bleach, ammonia etc.
  • Other: Household batteries, cosmetics, pool chemicals, shoe polish, lighter fluid, prescription medicines etc.

Each year, thousands of people are injured by exposure or accident involving hazardous household products.  Because of the dangers they pose. These products require special awareness, handling, and disposal.  In order to protect health and environment, every consumer should know how to properly use, store, and dispose of hazardous household products. 

Many common household products contain hazardous chemicals.  Once released into the environment, these substances may pose a serious threat to living organisms.  Small quantities of hazardous substances can accumulate over time to reach dangerous levels and contaminate the air, water, and soil. 

Here are some basic guidelines for managing household hazardous wastes:

  • Select the least toxic item and buying only the minimum quantity as required.
  • Read the entire label carefully for health warnings and use good judgment when choosing any product.
  • Store the product at a safe place and away from the children reach.
  • Avoid aerosol products.
  • Always use hazardous products in a well-ventilated area.
  • Never leave containers open.  Many products are volatile, evaporating quickly into the air. 
  • Always seal containers tightly after use.
  • Never mix chemicals and hazardous products. 
  • Do not use spent chemical containers for other purposes.
  • Wear protective clothing such as gloves and a mask when dealing with any hazardous material. 
  • Wash clothing exposed to hazardous materials separately from other clothes.
  • Do not eat, drink or smoke while using hazardous products.
  • Clean up the place after using hazardous products. Carefully seal products and properly refasten all caps.
  • Never put hazardous products in food or beverage containers.
  • Keep products away from sources of heat, spark, flame or ignition.
  • Know where flammable materials are located in your home and how to extinguish them.
  • Keep a multi-purpose dry chemical fire extinguisher in your home.

CRISPR Gene Editing Set to Revolutionize Waste Management

When people think of waste management, gene editing probably does not come to most people’s minds. Yet the innovative CRISPR genome modification technology fits well within the confines of managing pollution and waste on the planet. In particular, scientists are looking at how CRISPR can help with bioremediation, or pollutant neutralization.

Why Neutralize Pollutants?

The planet is in dire need of help as the negative impact of climate change hovers on the horizon. One of the ways that researchers are revolutionizing waste management and environmentalism is by neutralizing the pollutants that are taking up space in our landfills and oceans.

Scientists have noticed that certain organisms are particularly good at removing toxins from pollutants while others have the advantage of immobilizing toxins. Researchers are connecting the dots in order to figure out how CRISPR can help make these processes more efficient.

CRISPR-Aided Bioremediation

While it is great that scientists have discovered microorganisms that can metabolize pollutants and produce less toxic matter, what if those properties could be expanded?

CRISPR researchers are trying to do just that by using genetic editing to transfer more advantageous genes to other organisms, thus giving them even more power over toxic pollutants. This would speed up the process of natural bioremediation techniques without adding high costs and dangers.

An Edge Over Traditional Techniques

Using CRISPR technology, especially the promising CRISPR/Cas9 lentiviral system, will not only speed up the process but it will do a better job than traditional methods of bioremediation. By using the gene editing technique, scientists can create more chemically superior microorganisms that have more advantageous enzymes. That results in better neutrality of harmful pollutants in the planet’s soil and oceans. In turn, this also ramps up molecular biodiversity, which improves the cleanup process.

Speaking of molecules, the CRISPR method targets different molecular processes within a microorganism’s cells, either to regulate an existing gene or to create an entirely new one. When looking at a particular gene, scientists analyze its ability to target pollutants as well as its process for remediation.

Enhancing Bioremediation with CRISPR

Experts need to keep several aspects in mind when improving the abilities of a remediating organism and ramping up its efficiency. First of all, they need to look at the molecular pathways that lead an organism to remediate or neutralize a pollutant. Are there changes or improvements scientists that can make to these pathways? What can they add or take away?

They do a similar thing with the organism’s enzymes. Next comes bioprocessing and biosensor development, which allows scientists to test the microbial cells for chemical testing and removal efficiency.

Removing Harmful Pollutants

Take mercury, for example, which is a metal that is harmful to the planet as well as those who live on it. The E. coli bacteria has a removal efficiency of 96 when it comes to eradicating mercury.

Scientists can take that Hg2 gene and transporter and perhaps transport it to another microorganism that can metabolize and neutralize another type of pollutant. Researchers continue to look at how this technique can help us clean up the growing number of pollutants in the environment.

It is not just microorganisms that they’re working on, either. Genetic manipulation in plants is another exciting endeavor that could help out in the bioremediation field. By looking at the detoxification processes in certain plants, scientists are trying to figure out how to use CRISPR technology to amp up bioremediation or, rather, phytoremediation efforts.

Some human genes could be especially useful to certain plants that can target heavy metals in the soil. Whether they enhance existing plant species or generate completely new ones, this is an exciting development in remediation efforts against pollutants.

Waste Management in Qatar

Waste management is one of the most serious environmental challenges faced by the tiny Gulf nation of Qatar. mainly on account of high population growth rate, urbanization, industrial growth and economic expansion. The country has one of the highest per capita waste generation rates worldwide of 1.8 kg per day. Qatar produces more than 2.5 million tons of municipal solid waste each year. Solid waste stream is mainly comprised of organic materials (around 60 percent) while the rest of the waste steam is made up of recyclables like glass, paper, metals and plastics.

Municipalities are responsible for solid waste collection in Qatar both directly, using their own logistics, and indirectly through private sector contract. Waste collection and transport is carried out by a large fleet of trucks that collect MSW from thousands of collection points scattered across the country.

The predominant method of solid waste disposal is landfilling. The collected is discharged at various transfer stations from where it is sent to the landfill. There are three landfills in Qatar; Umm Al-Afai for bulky and domestic waste, Rawda Rashed for construction and demolition waste, and Al-Krana for sewage wastes. However, the method of waste disposal by landfill is not a practical solution for a country like Qatar where land availability is limited.

Solid Waste Management Strategy

According to Qatar National Development Strategy 2011-2016, the country will adopt a multi-faceted strategy to contain the levels of waste generated by households, commercial sites and industry – and to promote recycling initiatives. Qatar intends to adopt integrated waste hierarchy of prevention, reduction, reuse, recycling, energy recovery, and as a last option, landfill disposal.

A comprehensive solid waste management plan is being implemented which will coordinate responsibilities, activities and planning for managing wastes from households, industry and commercial establishments, and construction industry. The target is to recycle 38 percent of solid waste, up from the current 8 percent, and reduce domestic per capita waste generation.

Five waste transfer stations have been setup in South Doha, West Doha, Industrial Area, Dukhan and Al-Khor to reduce the quantity of waste going to Umm Al-Afai landfill. These transfer stations are equipped with material recovery facility for separating recyclables such as glass, paper, aluminium and plastic.

Domestic Solid Waste Management Centre

One of the most promising developments has been the creation of Domestic Solid Waste Management Centre (DSWMC) at Mesaieed. This centre is designed to maximize recovery of resources and energy from waste by installing state-of-the-art technologies for separation, pre-processing, mechanical and organic recycling, and waste-to-energy and composting technologies. At its full capacity, it will treat 1550 tons of waste per day, and is expected to generate enough power for in-house requirements, and supply a surplus of 34.4 MW to the national grid.

Future Outlook

While commendable steps are being undertaken to handle solid waste, the Government should also strive to enforce strict waste management legislation and create mass awareness about 4Rs of waste management viz. Reduce, Reuse, Recycle and Recovery. Legislations are necessary to ensure compliance, failure of which will attract a penalty with spot checks by the Government body entrusted with its implementation.

Improvement in curbside collection mechanism and establishment of material recovery facilities and recycling centres may also encourage public participation in waste management initiatives. When the Qatar National Development Strategy 2011-2016 was conceived, the solid waste management facility plant at Mesaieed was a laudable solution, but its capacity has been overwhelmed by the time the project was completed. Qatar needs a handful of such centers to tackle the burgeoning garbage disposal problem.

An Introduction to Composting

The composting process is a complex interaction between organic waste and microorganisms. The microorganisms that carry out this process fall into three groups: bacteria, fungi, and actinomycetesActinomycetes are a form of fungi-like bacteria that break down organic matter. The first stage of the biological activity is the consumption of easily available sugars by bacteria, which causes a fast rise in temperature. The second stage involves bacteria and actinomycetes that cause cellulose breakdown. The last stage is concerned with the breakdown of the tougher lignins by fungi.

Central solutions are exemplified by low-cost composting without forced aeration, and technologically more advanced systems with forced aeration and temperature feedback. Central composting plants are capable of handling more than 100,000 tons of biodegradable waste per year, but typically the plant size is about 10,000 to 30,000 tons per year. Biodegradable wastes must be separated prior to composting: Only pure foodwaste, garden waste, wood chips, and to some extent paper are suitable for producing good-quality compost.

Composting Equipment

The composting plants consist of some or all of the following technical units: bag openers, magnetic and/or ballistic separators, screeners (sieves), shredders, mixing and homogenization equipment, turning equipment, irrigation systems, aeration systems, draining systems, bio-filters, scrubbers, control systems, and steering systems. The composting process occurs when biodegradable waste is piled together with a structure allowing for oxygen diffusion and with a dry matter content suiting microbial growth.

Biodegradable wastes must be separated prior to composting: Only pure food waste, garden waste, wood chips, and to some extent paper are suitable for producing good-quality compost.The temperature of the biomass increases due to the microbial activity and the insulation properties of the piled material. The temperature often reaches 65 to 75 degrees C within few days and then declines slowly. This high temperature hastens the elimination of pathogens and weed seeds.

Composting Methodologies

The methodology of composting can be categorized into three major segments—anaerobic composting, aerobic composting, and vermicomposting. In anaerobic composting, the organic matter is decomposed in the absence of air. Organic matter may be collected in pits and covered with a thick layer of soil and left undisturbed six to eight months. The compost so formed may not be completely converted and may include aggregated masses.

Aerobic composting is the process by which organic wastes are converted into compost or manure in presence of air and can be of different types. The most common is the Heap Method, where organic matter needs to be divided into three different types and to be placed in a heap one over the other, covered by a thin layer of soil or dry leaves. This heap needs to be mixed every week, and it takes about three weeks for conversion to take place. The process is same in the Pit Method, but carried out specially constructed pits. Mixing has to be done every 15 days, and there is no fixed time in which the compost may be ready.

Berkley Method uses a labor-intensive technique and has precise requirements of the material to be composted. Easily biodegradable materials, such as grass, vegetable matter, etc., are mixed with animal matter in the ratio of 2:1. Compost is usually ready in 15 days.

Vermicomposting involves use of earthworms as natural and versatile bioreactors for the process of conversion. It is carried out in specially designed pits where earthworm culture also needs to be done. Vermicomposting is a precision-based option and requires overseeing of work by an expert. It is also a more expensive option (O&M costs especially are high).

Waste Management and Sustainability

Waste management is one of the core themes of sustainability, but achieving sustainable waste management is a challenging and complex task. Despite the fact that an increasing amount of waste has been reused and recycled, landfills still play an important role in the management of wastes. However, waste degradation in landfill produce leachate and harmful gasses viz. carbon dioxide, methane which are considered as greenhouse gases. It has been studied that leachate contribute to 20% emission of greenhouse gases. This can largely risk human health as well as threat to environment. Furthermore, it contains low concentration of gases with heavy aromatic rings, most of them are toxic in nature.

The increasing cost of waste disposal is a cause of major concern in developing nations

Movements of leachate create problem as aquifers need more time for rehabilitation. Leachate can migrate to groundwater or surface water and have potential threat to drinking water. Constructing landfills have adverse effects on aquaculture and habitats by diffusing leachate into surface/groundwater with limited on-site recycling activities. Various studies also claim that residential areas close to landfill areas have low housing values because people don’t prefer to live close to the area enriched with flies, mosquitoes, bacteria and bad odours.

The lower calorific value of wastes lowers the significance of waste-to-energy technologies, such as incineration/gasification, and make waste-to-energy less viable as solution for waste management solution. The low calorific value is an important outcome of waste collection process.

Scavengers often collect in a mixed state with all type of wastes, which include reusable materials, plastic, glass bottles etc. which reduces the calorific value and combustibility of waste. Waste is usually sorted out manually and unfortunately it becomes very difficult to regulate and implement an efficient method. This kind of waste recovery methods is very common in Asian countries e.g. India, Indonesia etc. using improper waste management technique can cause contaminated soil, water and environment.

Water is most easy to contaminate as it dissolves chemicals easily, causing harm to all living organisms including humans. Animal and marine life is most effected with water contamination. It also restricts our use of water for drinking and cooking purposes without cleaning system. The environment is highly harmed because of improper waste management.

Greenhouse gases are generated from decomposition of waste, these gasses are major cause of global warming affecting air precipitation, causing acid rain to severe hailstorms. Moreover humans who live near to garbage dumping area are found to be most significant to risk of health diseases, skin problems, cancer etc.

Olusosun is the largest dumpsite in Nigeria

With proper awareness and teaching methods of efficient waste management we can achieve sustainable solution to waste management. It has been forecasted by Environmental Sanitary Protection Plan that, by 2020 Kamikatsu a city in Japan is going to be 100% free from waste. Although the target of reaching the 100% waste is going to be achieved but the standby waste issue is going to be major hurdle as Kamikatsu have only 34% of land space available.

The lack of availability of standby space for waste is going to be major problem in future because of shortage of space, degraded quality of waste with lower calorific value and formation of leachate. And unfortunately, this issue is not going to be solved very soon.

Recycling of Lead-Acid Batteries in Developing Countries

Lead-acid batteries (also known as LABs) are a common item in our daily lives. Once the lead of the battery is timed out, we have no option but to dump it because it has no use for us anymore, but the copper plates in the battery remain reusable which can be used for recycling. There are some disagreements about the benefits of recycling battery, say alkaline battery, over simple disposal because the mercury in the battery no longer exists and the disposal material is abundant and non-toxic. But for automotive batteries the scenario is different in terms of benefits. The recycling of this type of battery holds both economic and environmental benefits.

The reusable material from the used battery is removed and recycled which reduces the needs for raw materials which is originally imported from abroad. It creates a balance payment and cost. In addition to this there can be considerable environmental impact during mining processes such as emission from smelting of sulfide ore, copper, nickel, and cobalt and this can be eliminated if recycling can be introduced.

Dangers of Lead-Acid Batteries

LABs generally consist of both sulphuric acid and large amount of lead which is not only corrosive but also a good carrier for soluble lead and lead particles. Lead is highly toxic metal which causes a wide range of adverse health effect especially on young children. If one gets expose excessively to lead it can cause damage to brain and kidney, impair hearing, and can led to various other associated problems. On an average an automobile manufactured contain about 12kg of lead, in which about 96% of lead is used in lead acid battery and remaining 4% is used in other applications like wheel balance weight, protective coating and variation dampers.

Both lead and cadmium are harmful for human health and environment. This toxic substances seeps into the soil, groundwater and surface water through landfill and also releases toxins into the air when they are burnt in municipal waste incinerators. Moreover cadmium can be easily absorbed by the pant root and get into the fruits, vegetables, and waters are consumed by animals and human beings, they can fall to prey to a host of ill effects. Studies have shown that nausea, excessive salivation, abdominal pain, liver and kidney damage, skin irritation, headaches, asthma, nervousness, decreased IQ in children, and sometimes even cancer can result from exposure to such metals for a sufficient period of time.

Need for Effective Control Measures

In a battery recycling plant, effective control measures need to be implemented, both to protect the health of workers and to prevent pollution of the environment. Good plant design, with reduction of the potential for the emission of contaminating substances is of utmost importance and the newer smelting processes are inherently much cleaner than traditional blast furnaces.

Pollution abatement technologies, including the treatment of exhaust gases and liquid effluents, need to be installed. Those mostly exposed to releases within the plants are the workforce. Control measures such as maintaining minimum standards of air quality within the works, medical surveillance of employees, use of protective equipment, and provision of conditions of good hygiene in general, is necessary to avoid occupational lead exposure. However, few government/non-governmental steps have been taken yet; rather this practice is a traditional trading system as prevail in the society.

Positive and Negative Impacts

In developing countries such as Bangladesh, recycling or reusing of used lead-acid batteries has both positive and negative impact on environment. Positive impact is that, if battery is recycled in proper and in sustainable manner it saves environment from toxic material of battery, otherwise battery waste is dumped into the landfills. Negative impact is that if recycling is not done in sustainable manner emits gases produced from battery recycling has adverse impacts on environment and human being.

In a battery recycling plant, effective control measures are required to safeguard public health and environment.

Direct recycling process should be banned as it has adverse impact on environment. As it is an illegal process, shopkeepers perform this process in hidden way. Government should impose the law and regulation strictly in this occurrence. This information can be used for advertising material highlighting the environmental benefits of recycling or reusing encourages the purchasing of old lead acid battery. It will accelerate the selling rate of old battery.

Importance of Awareness

Necessary steps should be taken to increase awareness about environmental impacts of used lead acid batteries. Proper instruction should be provided among the general mass. It will also increase reusing of old battery. Battery regeneration is a unique process specially designed to revive the lost capacity of batteries and give priority to choose secondary battery. Battery Reuse Centre can be developed for effective reuse and recycle.

The aim to divert reusable battery, donated by the public, which often could have been destined for landfill and instead provides a much needed source of low-cost battery to those in need. The battery reuse service encourages volunteer involvement and trainee placements in all aspects of its operation. Awareness program (posters, pamphlets, TV & radio commercials, road-shows, website, exhibitions, talks), infrastructure, information center, tax rebates for manufacturers should be taken to increase recycling or reusing of old battery.

E-Waste Management in the GCC: Perspectives

The growing amount of e-waste is gaining more and more attention on the global agenda. In 2017, e-waste production is expected to reach up to 48 million metric tons worldwide. The biggest contributors to this volume are highly developed nations, with the top three places of this inglorious ranking going to Norway, Switzerland and Iceland.

In Norway, each inhabitant produces a massive 28.3 kg of e-waste every year. Not far behind the top ten of this ranking lie GCC member states, with both Kuwait and UAE producing each 17.2 kg e-waste per capita per year. Saudi Arabia with its many times larger population produces least e-waste per capita among all GCC countries, with 12.5 kg a year.

Link between Development and E-Waste

Recent research suggests that there is evidence of a strong link between economic development and the generation of e-waste.  Due to rapid urbanization growth rates along with a substantial increase in the standard of living, more people develop a consumerist culture. With rising disposable income, people replace their technology more frequently, as soon there are upgraded gadgets on the market. This development is aggravated by technological progress, which renders shorter life spans of products.

Complexity of E-Waste

E-waste is not only a fast-growing waste stream but also complex, as it contains a large variety of different products. This makes it extremely difficult to manage. The rapid technology development and the emergence of items such as smart clothes will render e-waste management even more difficult in the future. Dealing with e-waste is not only toxic for workers with direct contact to it, but also the dumpsites on which e-waste is stored can have severe environmental impacts on the surrounding areas. Many developed countries export the bulk of their e-waste to developing countries, where it is recovered using extremely harmful methods for both human and the environment.

Out of the total e-waste produced world-wide, only about 15% are collected by official take-back schemes. The European Union is one of the few regions in the world with uniform legislation regarding the collection and processing of e-waste. The WEEE (Waste Electrical and Electronic Equipment) Directive took effect in 2003 and was designed to make manufacturers of appliances responsible for their equipment at the end of its life, a system known as extended producer responsibility (EPR).

An Untapped Opportunity

However, e-waste should not only be seen as a problem which more and more developed countries have to face. According to statistics, the intrinsic material value of global e-waste is estimated to be 48 billion euros in 2014. Even though the large part of e-waste constitutes of iron and steel, precious metals such as gold, copper, palladium, silver, platinum, cobalt, and more provide economic incentive for recycling.  In addition to the intrinsic material value, there are more benefits to e-waste recycling, such as job and employment creation.

In addition to these economic benefits, the recycling of electronic waste products also ensures to reduce environmental pollution by conserving virgin resources, whose extraction goes along with severe damages to entire ecosystems.

Situation in GCC Countries

In almost all GCC countries, there is minimal to zero legislation on e-waste, with minor differences between the respective counties. Kuwait as one of the biggest per capita e-waste producers among the GCC nations uses the same landfills for both conventional and e-waste. Bahrain operates only one landfill for the entire country, but there are several recycling initiatives in place, aiming at separating plastics, metals and paper. Still, there is no comprehensive law on e-waste management. Saudi Arabia possesses the biggest total amount of e-waste among the GCC countries. There are private companies, initiatives and Non-Profit-Organizations currently working on e-waste recycling, but there is no regulated system in place.

Oman does not have regulations or facilities to deal with e-waste, but the country has recently stated the realization of a need for it. Qatar has also recognized the need to address the waste management issue, but no concrete actions have been taken. The most advanced momentum regarding e-waste of all GCC countries can be found in the UAE. In some waste management centers, there are facilities where e-waste is classified and sorted out specifically. The UAE government is currently developing regulation and facilities to for sound e-waste recycling.

The Way Forward

As we have seen, in many GCC countries the need for e-waste legislation is widely recognized. E-waste management provides an opportunity and a huge potential in the entire Middle East, primarily due to four reasons. First, e-waste management is a source of employment for both highly skilled and unskilled workers. This could help to transfer employment from the public to the private sector, which is a goal of many Gulf countries. Second, e-waste recycling can also minimize costs, as less landfill space is being used. In Bahrain, the only existing landfill is expected to reach its capacity in the next years, and poses furthermore a health risks for the population as it is close to urban areas.

The most advanced momentum regarding e-waste in the GCC can be found in the UAE.

Third, the intrinsic value of e-waste with its precious metals provide economic incentive for recycling. As reserves for many metals decrease drastically, the economic value of these resources is expected to increase. And fourth, developments in e-waste management provide opportunities for industry and environmental research. Innovative and efficient recycling processes could be developed and transferred to other countries.

In order to fulfill this potential for e-waste management in GCC countries, the first step is to develop a sound regulatory framework in order to ensure private sector participation. Additionally, programs to increase public awareness for waste and in specific e-waste need to be developed, which is necessary for an integrated e-waste management system.

Solid Waste Management – History and Future Outlook

The disposal of municipal solid waste is the second most major concern for public health in developing countries because of population explosion, rampant poverty and high urbanization rates combined with poor government funding to curb waste management. Factors such as waste composition, technologies and lack of infrastructure have been found to set apart the good management of solid wastes in developing nations. Municipal waste is mainly comprised of paper, vegetable matter, plastics, metals, textiles, rubber and glass. In some countries (developing as well as developed), municipal solid waste is mixed with medical wastes and this may pose health risk to waste handlers and general public.

Burying the wastes has become most preferred method for waste management in many countries. This method is still used in many more countries. Tackling environmental issues has become more important and more preferred than pollution and consumption of unsustainable utilization of resources. Most importantly, the primary objective of waste management is to put emphasis on protecting the people and environment from potentially harmful effects of waste.

Methods of Solid Waste Management

Depending on the types of wastes generated, four methods of solid waste management has been used throughout the history, i.e. dumping, incineration, recycling and waste prevention. Waste generated from household is much different from industrial waste, agricultural waste, medical waste or mining wastes.

When wastes contain any hazardous component, or it has capability to become hazardous with time, poses very serious threat to environment and health. Hazardous wastes generated needs to be handled very carefully, with special techniques. This is one of the major reasons of open landfills are getting replaced with sanitary landfills.

At a landfill, wastes are covered with thick layer of soil. By the late 1950, this practice was very common for waste management across the world. Earlier landfills had considerable sludge and methane emissions, which were harmful to the environment as well as animal and human health. But these issues have been resolved largely by modern disposal methods, which were developed around 20 years ago. Modern landfills are equipped with thick layer of clay followed by plastic sheets. This method was practiced by some nations and still going on.

In 1930-1940, many cities in USA adopted new technology to curb waste issues by burning at high temperature, this method is known as incineration. During initial years, this method was not very efficient and emit very large amount of poisonous gasses, this is the major reason of incinerators shut down during that period. During mid-1970s, scientists modified incinerators to generate energy, which are known as waste to energy plants. But after around a decade, it has become major issue to build these plants, again because of emission issues.

With development of technology, waste burning in advanced form of incinerators became common in 1970s, researchers across the world bet on incinerators or waste to energy plants for solution to energy crisis in 1973. However, with realisation of impact on environment and air quality, it become very difficult to find location to build any waste to energy plants, mainly because of public opposition. Another issue with incinerator is production of ashes, which contain huge amount of heavy metals, toxic and inorganic compounds.


Incineration is the most common waste-to-energy method used worldwide.

Future Outlook of Solid Waste Management

The overall concept of wastes needs to be considered economically, it will be more considered as economically viable product if waste is considered as an inefficiency of the production process not as rejected residue of waste product. A permanent rejection or heavy restriction into products which produces waste that cannot be accumulated back into the environment safely.

The major challenge in waste management is to persuade people/community to consider waste as a resource, rather than a liability on society, which can be created with more innovation and technological development of manufacturing industry, waste processing industry and new business model and plans.

This planning system will create circular economy where product value created by inputs (e.g. energy, materials, labour etc.) is extended by enabling a material that goes into circular economy, beyond product life. We go from mineral to metals to product then back to minerals/metals. By understanding economic cycle of waste, people will understand the creation of opportunities to more sustainable product in future with limited resources.
