Waste Management Outlook for India

Waste management crisis in India should be approached holistically; while planning for long term solutions, focus on addressing the immediate problems should be maintained. National and local governments should work with their partners to promote source separation, achieve higher percentages of recycling and produce high quality compost from organics. While this is being achieved and recycling is increased, provisions should be made to handle the non-recyclable wastes that are being generated and will continue to be generated in the future.

Recycling, composting and waste-to-energy are all integral parts of the waste disposal solution and they are complementary to each other; none of them can solve India’s waste crisis alone. Any technology should be considered as a means to address public priorities, but not as an end goal in itself. Finally, discussion on waste management should consider what technology can be used, to what extent in solving the bigger problem and within what timeframe.

Experts believe India will have more than nine waste-to-energy projects in different cities across India in the next three years, which will help alleviate the situation to a great extent. However, since waste-to-energy projects are designed to replace landfills, they also tend to displace informal settlements on the landfills. Here, governments should welcome discussions with local communities and harbor the informal recycling community by integrating it into the overall waste management system to make sure they do not lose their rights for the rest of the city’s residents.

This is important from a utilitarian perspective too, because in case of emergency situations like those in Bengaluru, Kerala, and elsewhere, the informal recycling community might be the only existing tool to mitigate damage due to improper waste management as opposed to infrastructure projects which take more than one year for completion and public awareness programs which take decades to show significant results.

Involvement of informal recycling community is vital for the success of any SWM program in India

Indian policy makers and municipal officials should utilize this opportunity, created by improper waste management examples across India, to make adjustments to the existing MSW Rules 2000, and design a concrete national policy based on public needs and backed by science. If this chance passes without a strong national framework to improve waste management, the conditions in today’s New Delhi, Bengaluru, Thiruvananthapuram, Kolkata, Mumbai, Chennai, Coimbatore and Srinagar will arise in many more cities as various forcing factors converge. This is what will lead to a solid waste management crisis affecting large populations of urban Indians.

The Indian Judiciary proved to be the most effective platform for the public to influence government action. The majority of local and national government activity towards improving municipal solid waste management is the result of direct public action, funneled through High Courts in each state, and the Supreme Court. In a recent case (Nov 2012), a slew of PILs led the High Court of Karnataka to threaten to supersede its state capital Bengaluru’s elected municipal council, and its dissolution, if it hinders efforts to improve waste management in the city.

In another case in the state of Haryana, two senior officials in its urban development board faced prosecution in its High Court for dumping waste illegally near suburbs. India’s strong and independent judiciary is expected to play an increasing role in waste management in the future, but it cannot bring about the required change without the aid of a comprehensive national policy.

The Technology Revolutionizing Commercial Waste Management

Every single one of us can do something to improve our impact on the planet, but it is a given that businesses of all sizes have a bigger footprint than families – commercial accounts for 12% of total greenhouse gas emissions. A big factor of that is waste management. From the physical process of picking up garbage, to the methane-released process of decomposition, there are numerous factors that add up to create a large carbon footprint.

Between hiring green focused waste management solutions and recycling in a diligent fashion, there are a few technologies that are helping to break down the barrier between commercial waste management and an environmentally positive working environment.

Cleaning up commercial kitchens

A key form of commercial waste is food waste. Between the home and restaurant, it is estimated by the US Department of Agriculture that 133 billion pounds of food is wasted every year. Much will end up in the landfill. How is technology helping to tackle this huge source of environmental waste? Restaurants themselves are benefiting from lower priced and higher quality commercial kitchen cooking equipment, that helps to raise standards and reduce wastage.

Culinary appliances for varied cuisines also benefit from a new process being developed at the Netherland’s Wageningen University. A major driver of food waste is rejected wholesale delivery, much of which will be disposed of in landfill. The technology being developed in Holland aims to reduce wastage by analyzing food at the source, closer to where recycling will be achievable.

Route optimization

Have you ever received a parcel from an online retailer only to find the box greatly outsizes the contents? On the face of it, this is damaging to the environment. However, many retailers use complex box sorting algorithms. The result is that the best route is chosen on balance, considering the gas needed to make the journey, the amount of stock that can be delivered and the shortest route for the driver. This is an area of intense technological innovation.

The National Waste & Recycling Association reported in 2017 on how 2018 would see further advances, particularly with the integration of artificial intelligence and augmented reality into the route-finding process.

Balancing the landfill carbon footprint

It is well established that landfills are now being used to power wind turbines, geothermal style electricity and so on. They are being improved to minimize the leachate into groundwater systems and to prevent methane escaping into the atmosphere. However, further investigation is being pushed into the possibility of using landfill as a carbon sequester.

AI-based waste management systems can help in route optimization and waste disposal

Penn State University, Lawrence Berkeley and Texas University recently joined together to secure a $2.5m grant into looking into the function of carbon, post-sequestration. This will help to shed light on the carbon footprint and create a solid foundation on which future technology can thrive.

Businesses of all sizes have an impact on the carbon footprint of the world. The various processes that go into making a business profitable and have a positive impact on their local and wider communities need to be addressed. As with many walks of life, technology is helping to bridge the gap.

Things to Consider While Hiring a Waste Management Company

Whether talking about recycling for a home or business, this type of service is extremely important for the environment. Waste has a negative impact on the environment and can cause pollution of many kinds. Most companies that offer both garbage and recycling services are very organized, and consumers are expected to be equally organized in sorting their waste and separating it from recyclable items.

Because the process of figuring out what can be recycled, many individuals and business owners find it is much easier to simply hire a waste management company.

Below are some questions to consider when looking for recycling services and reasons why hiring a waste management company can take the guesswork out of recycling.

What Kind of Recycling Service is Required?

This can mean anything from home to office to hazardous waste to syringe collection services.  Some companies offer all types of recycling and provide the different skip bins necessary to mitigate these needs. It is important to contact the company and find out as much information that is needed to make an informed decision on how recycling is handled.

However, most companies will only offer a general list of items that can be recycled, including plastics, cardboards, glass, etc. This list will not be exhaustive, leaving many consumers to wonder what to do with items such as plastic bottle caps, milk cartons and the like. A waste management company will know the specific regulations for what can and cannot be recycled, eliminating the hassle for you.

What Can Be Recycled?

Bricks, wood, paper, metals, cardboard, plastics, concrete, and green waste can all be recycled.

  • Bricks – These are broken down and crushed in order to be made into new bricks.
  • Wood – Wood can be used again as a building material or can be processed into pulp or mulch. Recycling wood can limit the number of trees that are being cut down.
  • Paper – The process for this material mixes old paper with chemicals and water to break it down. It is then chopped, heated and broken down further into strands of cellulose.  This substance is then called slurry or pulp and is further recycled into new paper.
  • Metals – Recycling metals will not alter its properties, the most common metals recycled are steel and aluminum.
  • Cardboard – This uses a process that reuses thick sheets of multilayered papers (cardboard) that have been discarded.
  • Plastics – The recycling process for plastics recovers waste or scraps of plastic and reprocesses them into useful products.
  • Concrete – This type of recycling is becoming more common and uses a process of reuse of the rubble for new construction endeavors.
  • Green Waste – This can be anything from leaves to grass trimmings to flower cuttings that can be decomposed and then recycled. This will in turn produce what is called green waste.

There are a number of items that can be recycled, but it is important to note that not all recycling pickup services will be able to process all the items mentioned above. Certain materials, such as concrete or wood, must be disposed of at specific facilities.

plastic-wastes

Recycling has unending benefits

For the average homeowner, this can mean having to locate the specific facility and transport the recyclable materials to them. A waste management company will have the contacts in the industry to know where to take any type of recyclable item and can take care of the transportation for you.

What Recycling Techniques Are Used, and Are They Legal and Ethical?

  • Concretes and Aggregates – This process would involve using a crushing machine and combining the concrete with bricks, asphalt, dirt and rocks. The smaller pieces will be used as gravel, crushed concrete can all be used as dry aggregate, which in turn can be used to make new concrete that will be free of contaminates.
  • Batteries – This type of recycling can be very difficult; all batteries must be sorted into groups of similar kinds and require. Older batteries contain cadmium and mercury, which are very harmful and must be handled very carefully.
  • Biodegradable Waste – This type of waste can be made into reusable material via the process of biological decomposition. The two mechanisms that help this to occur are composting or converting it into soil improver and biogas. The latter uses anaerobic digestion where organic wastes are broken down by microorganisms in a biogas plant.

Again, a waste management company will be able to guarantee that your recycling ends up in the right processing facilities and to ensure that it does get processed according to government regulations and ethical means. When the wrong items end up in recycling, this can lead to an entire batch being thrown out. A waste management company will make sure that the recyclable items are properly sorted, helping to ensure that your efforts to recycle do not go to waste.

What Are the Benefits of Recycling?

There are many benefits to using a recycling service. For instance, recycling conserves energy, reduces greenhouse gases, reduces water and air pollution, and conserves natural resources by reusing recycled materials. Protecting the environment is one of the most important things a home or business can do. When an individual or business chooses to recycle all different kinds of waste, it makes the world a better, less toxic place to live.

Not only does recycling help protect the world, it also reduces the need for extraction such as mining, logging and quarrying. It also reduces the need for processing and refining of raw materials. All these processes can contain harmful, substantial amounts of water and air pollution. Recycling will save this energy while reducing the amount of greenhouse gas, which in turn helps to attack climate change.

Why Going Green Is The Best Thing To 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 building construction 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.

college-green

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.

Conclusion

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.

3 Tips to Help Keep Your Sewer Line Cleared

A sewer back up can be one of the costliest, messiest and most stressful problems you will ever have to deal with. It is possible that raw sewage can back up into your toilet, sink and bathtub, eventually overflowing into key areas of your house. It’s admittedly a disgusting topic to talk about, but it does happen, and it is important to know how to prevent it. So, here are a few tips on how to clear a mainline blockage:

1. Clear Roots

These are the most common culprits behind sewer backups. Roots belonging to trees and shrubs seek moisture underground and can, therefore, make their way into sewer lines through cracks in the pipe. Typically, they start small but grow and eventually obstruct the line, allowing waste to build up and back up.

Here are some tips on using salt to get rid of such tree roots.

  • Obtain 4 pounds of rock salt and flush it down the toilet in the evening before the family goes to bed. That will give the saltwater at least 8 hours in the sewer line. For that duration, do not use any drains in the house to avoid diluting the saltwater.
  • After 8 hours, flush the toilet again and resume use of the drains in the house.
  • Follow this practice about once or twice a month. Any tree roots in the sewer line will die from the excess of sodium, and the lines will soon be clear.

2. Clear Paper Products

These include such products as paper towels, sanitary towels and diapers that are not intended for flushing. These products aren’t like toilet paper in that they do not disintegrate easily. They can, therefore, block the sewer line and cause a backup. To prevent this from happening, they should not be flushed down the toilet but should instead be thrown in the garbage.

Sanitary towels and diapers should never be flushed down the toilet as they tend to clog the sewer line the fastest. This also includes tampons. All of these should be disposed of in a specialized garbage bin placed next to the toilet, such as the ones in public restrooms.

3. Avoid Putting Grease in Drains

Grease is another culprit that has a way of causing backups. You should avoid, as much as possible, pouring grease down a drain. This also applies to cooking oil as it often has the same effect. Some people believe that using hot water to wash grease down the drain helps. That is not true. The grease will go down the drain more easily, but it will eventually cool off further down the drain and solidify. When it does that, it will clog the drain and cause a backup.  The line will have a harder time letting water through and get clogged.

The best solution is to pour the grease into a container that is resistant to heat and let it cool off. You can then dispose of it in the garbage.

Waste Management in Sweden: Perspectives

Sweden is considered as a global leader in sustainable waste management and in the reduction of per capita carbon footprint. The country consistently works to lower its greenhouse gas emissions, improve energy efficiency and increase public awareness. Over the past 10 years, Sweden developed methods of repurposing waste, so less than one percent of the total waste generated in the country makes it to landfills. To accomplish this, the country changed their perspective of garbage.

Increase Recycling

Recycling is a part of Swedish culture. Residents regularly sort recyclable materials and food scraps from other waste in their homes before disposal. This streamlines the recycling process and reduces the effort required to sort large volumes of waste at larger recycling centers. As another way to promote recycling, the Swedish government created legislation stating recycling centers must be within 1,000 feet of residential areas. Conveniently located facilities encourage citizens to properly dispose of their waste.

Repurpose Materials

Citizens are also encouraged to reuse or repurpose materials before recycling or disposing of them. Repurposing and reusing products requires less energy when compared to the recycling or waste disposal process. As Swedes use more repurposed products, they reduce the volume of new products they consume which are created from fresh materials. In turn, the country preserves more of its resources.

Invest in Waste to Energy

Over 50 percent of the waste generated in Sweden is burned in waste-to-energy facilities. The energy produced by these facilities heats homes across the country during the long winter months. Localized heating — known as district heating — has improved air quality throughout the nation. It’s easier and more economical to control the emissions from several locations as opposed to multiple, smaller non-point sources.

Another benefit of waste-to-energy facilities is that ash and other byproducts of the burning process can be used for road construction materials. As a whole, Sweden doesn’t create enough waste to fuel its waste to energy plants — the country imports waste from its neighbors to keep its facilities going.

In the early 1990’s, the Swedish government shifted the responsibility for waste management from cities to the industries producing materials which would eventually turn to waste. To promote burning waste for energy, the government provides tax incentives to companies which make more economically attractive.

Impact of Waste-to-Energy

Although Sweden has eliminated the volume of trash entering landfills, they have increased their environmental impacts in other ways. Waste-to-energy facilities are relatively clean in that most harmful byproducts are filtered out before entering the environment, though they still release carbon-dioxide and water as their primary outputs. On average, waste-to-energy plants generate nearly 20 percent more carbon-dioxide when compared to coal plants.

 

waste-management-sweden

Coal plants burn and release carbon which is otherwise sequestered in the ground and unable to react with the earth’s atmosphere. Waste-to-energy facilities consume and release carbon from products made of organic materials, which naturally release their carbon over time. The downside to this process is that it frees the carbon from these materials at a much faster rate than it would be naturally.

The reliance on the waste-to-energy process to generate heat and the tax incentives may lower Swedish motivation to recycle and reuse materials. The country already needs to import trash to keep their waste-to-energy plants running regularly. Another disadvantage of this process is the removal and destruction of finite materials from the environment.

Even though Sweden continues to make strides in lowering their environmental impact as a whole, they should reevaluate their reliance on waste to energy facilities.

Waste-to-Energy in Saudi Arabia

Urban waste management has emerged as a big challenge for the government and local bodies in Saudi Arabia. The country generates more than 15 million tons of municipal solid waste each year with per capita waste production estimated to be 2 kg per day, among the highest worldwide. Municipal waste production in three largest cities – Riyadh, Jeddah and Dammam – exceeds 6 million tons per annum which gives an indication of the enormity of the problem faced by civic bodies.

waste-jeddah

The Problem of Waste

Municipal waste generation in Saudi Arabia is increasing at an unprecedented rate. Due to high population growth rate, rapid urbanization and fast-paced economic development, MSW generation is expected to cross 30 million tons per year by 2033. More than 75 percent of Kingdom’s population is concentrated in urban areas, and collected garbage is thrown in landfills or dumpsites without any processing or treatment.

Most of the landfills in Saudi Arabia are non-sanitary and prone to problems like leachate, vermin, flies and spontaneous fires, apart from greenhouse gas emissions.  It has become necessary for the Saudi government to devise an integrated waste management strategy, using international best practices and modern technologies, to tackle heaps of garbage accumulating across the country.

Promise of Waste-to-Energy

Waste-to-energy provides a cost-effective and eco-friendly solution to both energy demand and MSW disposal problems in Saudi Arabia. Increasing waste generation, inability of existing solutions to tackle waste and expansion of cities into ex-dump sites are strong drivers for large-scale deployment of WTE systems in the Kingdom.

Saudi Arabia has tremendous waste-to-energy potential due to plentiful availability of good quality municipal waste. Modern waste-to-energy technologies, such as RDF-based incineration, gasification, pyrolysis and anaerobic digestion have the ability to transform power demand and waste management scenario in the country.

A typical 250 – 300 tons per day garbage-to-energy plant can produce around 3 – 4 MW of electricity and a network of such plants in cities around the country can make a real difference in waste management as well as energy sectors.  In fact, such plants also produce tremendous about of heat energy which can be utilized in process industries and district cooling systems, further maximizing their usefulness.

Key Challenges

Around the world, waste-to-energy finds wide acceptance as a tool to manage urban wastes, with more than 1,000 waste-to-energy plants in operation globally, especially in Europe, China and the Asia-Pacific. However, waste-to-energy is struggling to get off-the-ground in Saudi Arabia due to several issues, the main reason being the cheap and plentiful availability of oil which prevents decision-makers to set effective regulations for waste-to-energy development in the country.

Waste-to-Energy is widely accepted as a part of sustainable waste management strategy worldwide.

Waste-to-Energy is widely accepted as a part of sustainable waste management strategy worldwide.

Policy-makers in KSA should consider waste-to-energy as a sustainable waste management solution, rather than as a power-producing industry. Unlike Western countries, waste management services are practically free-of-cost for the waste generators which act as a deterrent for governmental investment in new waste management solutions and technologies, such as waste-to-energy. Infact, waste collection, transport and disposal methods in Saudi Arabia do not match the standards of a developed country.

Future Outlook

Vision 2030, touted as most comprehensive economic reform package in Saudi history, puts forward a strong regulatory and investment framework to develop Saudi waste-to-energy sector. An ambitious target of 3GW of energy from waste is to be achieved by 2025.  A methodical introduction of modern waste management techniques like material recovery facilities, waste-to-energy systems and recycling infrastructure can significantly improve waste management scenario and can also generate good business opportunities.

To sum up, environmental issues associated with non-sanitary landfills, ineffectiveness of prevalent waste management model and rising energy demand are key drivers for development of waste-to-energy sector in Saudi Arabia.

Waste Management Challenges in Middle East

Middle East is one of the most prolific waste generating regions worldwide with per capita waste production in several countries averaging more than 2 kg per day . High standards of living, ineffective legislation, infrastructural roadblocks, indifferent public attitude and lack of environmental awareness are the major factors responsible for growing waste management problem in the Middle East. Lavish lifestyles are contributing to more generation of waste which when coupled with lack of waste collection and disposal facilities have transformed ‘trash’ into a liability.

garbage-middle-east

Major Hurdles

The general perception towards waste is that of indifference and apathy. Waste is treated as ‘waste’ rather than as a ‘resource’. There is an urgent need to increase public awareness about environmental issues, waste management practices and sustainable living. Public participation in community-level waste management initiatives is lackluster mainly due to low level of environmental awareness and public education. Unfortunately none of the countries in the region have an effective source-segregation mechanism.

Waste management in Middle East is bogged down by deficiencies in waste management legislation and poor planning. Many countries lack legislative framework and regulations to deal with wastes. Insufficient funds, absence of strategic waste management plans, lack of coordination among stakeholders, shortage of skilled manpower and deficiencies in technical and operational decision-making are some of the hurdles experienced in implementing an integrated waste management strategy in the region. In many countries waste management is the sole prerogative of state-owned companies and municipalities which discourage participation of private companies and entrepreneurs.

Many Middle East nations lack legislative framework and regulations to deal with urban wastes.

Many Middle East nations lack legislative framework and regulations to deal with urban wastes.

Due to lack of garbage collection and disposal facilities, dumping of waste in open spaces, deserts and water bodies is a common sight across the region. Another critical issue is lack of awareness and public apathy towards waste reduction, source segregation and waste management.

A sustainable waste management system demands high degree of public participation, effective laws, sufficient funds and modern waste management practices/technologies. The region can hope to improve waste management scenario by implementing source-segregation, encouraging private sector participation, deploying recycling and waste-to-energy systems, and devising a strong legislative and institutional framework.

The Way Forward

In recent year, several countries, like Qatar, UAE and Oman, have established ambitious solid waste management projects but their efficacy is yet to be ascertained. On the whole, Middle East countries are slowly, but steadily, gearing up to meet the challenge posed by waste management by investing heavily in such projects, sourcing new technologies and raising public awareness.

However the pace of progress is not matched by the increasing amount of waste generated across the region. Sustainable waste management is a big challenge for policy-makers, urban planners and other stake-holders, and immediate steps are needed to tackle mountains of wastes accumulating in cities throughout the Middle East.

Solid Waste Management in Pakistan

Solid waste management situation in Pakistan is a matter of grave concern as more than 5 million people to die each year due to waste-related diseases. In Pakistan roughly 20 million tons of solid waste is generated annually, with annual growth rate of about 2.4 percent. Karachi, largest city in the country, generates more than 9,000 tons of municipal waste daily. All major cities, be it Islamabad, Lahore or Peshawar, are facing enormous challenges in tackling the problem of urban waste. The root factors for the worsening garbage problem in Pakistan are lack of urban planning, outdated infrastructure, lack of public awareness and endemic corruption.

Karachi-Garbage-Dump

Contributing Factors

Being the 6th most populated country in the world; there is a lot of consumerism and with it a great deal of waste being produced. Like other developing countries, waste management sector in Pakistan is plagued by a wide variety of social, cultural, legislative and economic issues.  In the country, more waste is being produced than the number of facilities available to manage it. Some of the major problems are:

  • There is no proper waste collection system
  • Waste is dumped on the streets
  • Different types of waste are not collected separately
  • There are no controlled sanitary landfill sites. Opening burning is common.
  • Citizens are not aware of the relationship between reckless waste disposal and resulting environmental and public health problems

As a result of these problems, waste is accumulating and building up on roadsides, canals, and other common areas and burning trash is common, causing hazardous toxins to be exposed thereby threatening human and environmental health. Among the already few landfill sites that are present, even fewer are in operation. Even within Pakistan’s capital, Islamabad, there are no permanent landfills to be found.

The waste on the roads allows for an ideal environment for various flies to thrive which effects both human health and the health of the environment for other species. The poor solid waste management in Pakistan has caused numerous diseases and environmental problems to rise.

Waste Management Situation in Lahore

In Lahore, the capital of Punjab and the second largest city in Pakistan, there are currently no controlled waste disposal facilities are formal recycling systems, though roughly 27% of waste (by weight) is recycled through the informal sector, Lahore does not have very high performing governmental management in the waste management situation. Instead, the City District Government Lahore established the Lahore Waste Management Company and left the responsibility of the Solid Waste Management in Lahore to them. Beginning in 2011, Lahore Waste Management Company strives to develop a system of SWM that ensures productive collection, recovery, transportation, treatment and disposal of the waste in Lahore.

Lahore Waste Management Company (LWMC) has over 10,000 field workers involved in waste collection and disposal. Though the LWMC is working in phases, 100% collection rates are not seen yet. Lahore currently only has three disposal sites which are no more than dumps, where illegal dumping and trash burning is common. However, there is some resource recovery taking place. It is estimated that 27% of dry recyclables are informally recycled within the city. Additionally a composting plant converts 8% of waste into compost.

In general, the governance over the Waste Management in Lahore is hardly present. Though there are current projects and plans taking place, by the Lahore Waste Management Company for example, in order to achieve a productive and sustainable system in the city it is necessary for all service providers (formal, private, and informal) to take part in decisions and actions.

Current Activities and Projects

According to the United Nations Environment Program, there are six current activities and plans taking place towards an efficient waste management system. These current activities are as follows:

  • Solid Waste Management Guidelines (draft) prepared with the support of Japan International Cooperation Agency (JICA), Japan.
  • Converting waste agricultural biomass into energy/ material source – project by UNEP, IETC Japan.
  • North Sindh Urban Services Corporation Limited (NSUSC) – Assisting the district government in design and treatment of water supply, sanitation and solid waste management
  • The URBAN UNIT, Urban Sector Policy & Management Unit P & D Department, Punjab. Conducting different seminars on awareness of waste water, sanitation & solid waste management etc.
  • Lahore Compost (Pvt.) Ltd. only dealing with the organic waste with the cooperation of city district government Lahore, Pakistan. The company is registered as a CDM project with UNFCCC.
  • Different NGOs are involved at small scale for solid waste collection, and recycling.

Additionally, in November 2013 a German company, agreed to invest in the installation of a 100 megawatt power plant which generates energy from waste from Lahore. Progress is being made on the country’s first scientific waste disposal site in Lakhodair. With this in mind, the Lahore Waste Management Company considered other possible technologies for their Waste-to-Energy project. They opened up applications for international companies to hire as the official consultant for LWMC and their project. The results of the feasibility study results showed that the power plant has the potential to process 1035 tons of municipal waste daily, and generate 5.50 megawatt electricity daily.

The Way Forward

Although SWM policies do exist, the levels at which they are implemented and enforced lack as a result of the governmental institutions lacking resources and equipment. These institutions are primarily led by public sector workers and politicians who are not necessarily the most informed on waste management. For improvements in municipal solid waste management, it is necessary for experts to become involved and assist in the environmental governance.

Due to the multiple factors contributing to the solid waste accumulation, the problem has become so large it is beyond the capacity of municipalities. The former director of the Pakistan Council of Scientific and Industrial Research, Dr. Mirza Arshad Ali Beg, stated, “The highly mismanaged municipal solid waste disposal system in Pakistan cannot be attributed to the absence of an appropriate technology for disposal but to the fact that the system has a lot of responsibility but no authority.” Laws and enforcement need to be revised and implemented. The responsibility for future change is in the hands of both the government, and the citizens.

Waste practices in the Pakistan need to be improved. This can start with awareness to the public of the health and environment impacts that dumped and exposed waste causes. It is imperative for the greater public to become environmentally educated, have a change in attitude and take action.

Solid Waste Management in Nigeria

Solid waste management is the most pressing environmental challenge faced by urban and rural areas of Nigeria. Nigeria, with population exceeding 170 million, is one of the largest producers of solid waste in Africa. Despite a host of policies and regulations, solid waste management in the country is assuming alarming proportions with each passing day.

Nigeria generates more than 32 million tons of solid waste annually, out of which only 20-30% is collected. Reckless disposal of MSW has led to blockage of sewers and drainage networks, and choking of water bodies. Most of the wastes is generated by households and in some cases, by local industries, artisans and traders which litters the immediate surroundings.

Improper collection and disposal of municipal wastes is leading to an environmental catastrophe as the country currently lack adequate budgetary provisions for the implementation of integrated waste management programmes across the States.

According to the United Nations Habitat Watch, African city populations will more than triple over the next 40 years. African cities are already inundated with slums; a phenomenon that could triple urban populations and spell disaster, unless urgent actions are initiated. Out of the 36 states and a federal capital in the country, only a few have shown a considerable level of resolve to take proactive steps in fighting this scourge, while the rest have merely paid lip services to issues of waste management indicating a huge lack of interest to develop the waste sector.

Scenario in Lagos

Lagos State, the commercial hub of Nigeria, is the second fastest growing city in Africa and seventh in the world.  The latest reports estimate its population to be more than 21 million making it the largest city in entire Africa.  With per capita waste generation of 0.5 kg per day, the city generates more than 10,000 tons of urban waste every day.

Despite being a model for other states in the country, municipal waste management is a big challenge for the Lagos State Waste Management Agency (LAWMA) to manage alone, hence the need to engage the services of private waste firms and other franchisee to reduce the burden of waste collection and disposal. One fundamental issue is the delayed collection of household solid waste.  In some cases, the wastes are not collected until after a week or two, consequently, the waste bin overflows and litters the surroundings.

Improper garbage disposal and lack of reliable transport infrastructure means that collected wastes are soon dispersed to other localities. Another unwelcome practice is to overload collection trucks with 5-6 tons of waste to reduce the number of trips; this has necessitated calls by environmental activist to prevail on the relevant legislature to conform to the modern waste transportation standard.

Situation in Oyo

Away from Lagos State, Oyo is another ancient town in Nigeria with an estimated population of six million people. Here, solid waste is regulated by the Oyo State Solid Waste Management Authority (OYOWMA). Unlike Lagos State, Oyo State does not have a proper waste management scheme that cuts across the nooks and crannies of the state, apart from Ibadan, the capital city, people from other towns like Ogbomoso and Iseyin resort to waste burning. In case the waste generators feels that the amount being charged by the waste franchisee is beyond their means, they dump the waste along flood paths thus compounding the waste predicament.

Kano and Rivers State with its fair share of population also suffers similar fate in controlling and managing solid waste. Generally speaking, population increase in Nigeria has led to an unprecedented growth in its economy but with a devastating effect on the environment as more wastes are generated due to the need for housing, manufacturing industries and a boost in trade volume.

Future Perspectives

The government at the federal level as a matter of urgency needs to revive its regulatory framework that will be attractive for private sectors to invest in waste collection, recycling and reusing.  The environmental health officer’s registration council of Nigeria would do well to intensify more effort to monitor and enforce sanitation laws as well as regulate the activities of the franchisees on good sustainable practices.

Taking the advocacy further on waste management, to avoid littering the environment, some manufacturing companies (e.g. chemical and paint industry) have introduced a recall process that will reward individuals who returns empty/used plastic containers. This cash incentive has been proven over time to validate the waste to wealth program embarked upon by the manufacturing companies. It is also expected that the government will build more composting and recycling plants in addition to the ones in Ekiti and Kano State to ensure good sustainable waste management.

Waste management situation in Nigeria currently requires concerted effort to sensitize the general public on the need for proper disposal of solid waste. Also, the officials should be well trained on professionalism, service delivery and ensure that other states within the country have access to quality waste managers who are within reach and can assist on the best approach to managing their waste before collection.
