WTE Prospects in the Middle East

A combination of high fuel prices and a search for alternative technologies, combined with massive waste generation has led to countries in the Middle East region to consider Waste to Energy (or WtE) as a sustainable waste management strategy and cost-effective fuel source for the future. We look at the current state of the WtE market in the Middle East.

It is estimated that each person in the United Arab Emirates produces 2 kg of municipal solid waste per day – that puts the total waste production figure somewhere in the region of 150 million tonnes every year. Given that the population currently stands at over 9.4 million (2013) and is projected to see an annual average growth figure of 2.3% over the next six years, over three times the global average, it’s clear that this is a lot of waste to be disposed of.

In addition, the GCC nations in general rank in the bottom 10% of the sustainable nations in the world and are also amongst the top per capita carbon-releasers.

When we also consider that UAE are actively pursuing alternative energy technologies to supplement rapidly-decreasing and increasingly-costly traditional fossil fuels, mitigate the harmful effects of landfill, and reduce an ever-increasing carbon footprint, it becomes apparent that high on their list of proposed solutions is Waste to Energy (WtE). It could be an ideal solution to the problem.

What is WtE

Waste-to-Energy works on the simple principle of taking waste and turning it into a form of energy. This can be electricity, heat or transport fuels, and can be achieved in a variety of ways – the most common of which is incineration. MSW is taken to a WtE plant, incinerated at high temperatures and the resultant heat is used to boil water which creates steam to turn turbines, in the same way that burning gas or coal produces power. Gasification and anaerobic digestion are two further WtE methods which are also used.

However, WtE has several advantages over burning fossil fuels. Primarily amongst them are the potential to minimise landfill sites which have caused serious concern for many years. They are not only unsightly, but can also be contaminated, biologically or chemically. Toxic waste can leach into the ground beneath them and enter the water table.

Landfill sites also continuously emit carbon dioxide and methane, both harmful greenhouse gases – in addition methane is potentially explosive. Sending MSW to landfill also discourages recycling and necessitates more demand for raw materials. Finally, landfill sites are unpleasant places which attract vermin and flies and give off offensive odours.

Waste to Energy Around the World

WtE has been used successfully in many countries around the world for a long time now. Europe is the most enthusiastic proponent of WtE, with around 450 facilities; the Asia-Pacific region has just over 300; the USA has almost 100. In the rest of the world there are less than 30 facilities but this number is growing. Globally, it is estimated that the WtE industry is growing at approximately US $2 billion per annum and will be valued at around US $80 billion by the year 2022.

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

The USA ranks third in the world for the percentage of waste which is incinerated for energy production. Around 16% of the rubbish that America produces every day is burned in its WtE plants. Advocates claims the advantages are clear:

  • reducing the amount of greenhouse gas emitted into the environment (estimates say that burning one ton of waste in a WtE plant saves between one half and one ton of greenhouse gases compared to landfill emissions, or the burning of conventional fuels),
  • freeing up land which would normally be used for landfill (and, therefore, extending the life of existing landfill sites),
  • encouraging recycling (some facilities have managed to reduce the amount of waste they process by up to 90% and the recycling of ferrous and non-ferrous metals provides an additional income source), and,
  • most importantly, producing a revenue stream from the sale of the electricity generated.

In one small county alone, Lancaster, Pennsylvania, with a population of just over half-a-million people, more than 4.4 billion kWh of electricity has been produced through WtE in the last 20 years. This has generated over USD $256 million through its sale to local residents.

Waste-to-Energy in the Middle East

Given WtE’s potential to not only reduce greenhouse gas emissions and pollution on a local scale, but also to produce much-needed electricity in the region, what is the current state of affairs in the Middle East. There are several WtE initiatives already underway in the Middle East.

Qatar was the first GCC country to implement a waste-to-energy programme and currently generates over 30MW of electricity from its Domestic Solid Waste Management Center (DSWMC) located at Messeid (Doha). Saudi Arabia and the UAE have both stated that they have WtE production capacity targets of 100MW. Bahrain, Kuwait and Oman are also seriously considering waste-to-energy as a means to tackle the worsening waste management problem.

Abu Dhabi’s government is currently spending around US $850 million to build a 100 MW plant which will supply around 20,000 households with electricity. In Sharjah, the world’s largest household waste gasification plant, costing in excess of US $480 million, is due to be open soon.

However, not all the GCC members are as enthusiastic about WtE. Dubai’s government has recently scrapped plans for a US $2 billion project which would have made use of the 7,800 tonnes of domestic waste which is produced in Dubai every single day.

We asked Salman Zafar, Founder of Doha-based EcoMENA, a popular sustainability advocacy, why given the sheer scale of the waste in the Gulf region, the production of this form of energy is still in its infancy. “The main deterrent in the implementation of WtE projects in the Middle East is the current availability of cheap sources of energy already available, especially in the GCC,” he commented.

Salman Zafar further says, “WtE projects demand a good deal of investment, heavy government subsidies, tipping fees, power purchase agreements etc, which are hard to obtain for such projects in the region.” “The absence of a sustainable waste management strategy in Middle East nations is also a vital factor behind the very slow pace of growth of the WtE sector in the region. Regional governments, municipalities and local SWM companies find it easier and cost-effective to dump untreated municipal waste in landfills,” he added.

So, how can WtE contribute towards the region’s growing power demand in the future?

“Modern WtE technologies, such as RDF-based incineration, gasification, pyrolysis, anaerobic digestion etc, all have the ability to transform power demand as well as the waste management scenario in the region,” he continued. “A typical 250 – 300 tons per day WtE plant can produce around 3 – 4 MW of electricity and a network of such plants in cities across the region can make a real difference in the energy sector as well as augmenting energy reserves in the Middle East. In fact, WtE plants also produce a tremendous about of heat energy which can be utilised in process industries, further maximising their usefulness,” Salman Zafar concluded.

New technologies naturally take time to become established as their efficiency versus cost ratios are analysed. However, it is becoming increasingly clearer that waste-to-energy is a viable and efficient method for solid waste management and generation of alternative energy in the Middle East.

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.

landfill-qatar

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 in Qatar 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 treats 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. Legislation 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.

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 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.

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.

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.

Composting in Qatar: An Overview

Composting in Qatar is mainly done at the Domestic Solid Waste Management Centre (DSWMC) in Mesaieed, which houses the largest composting facility in the country and one of the largest in the world.  The waste that enters the plant initially goes through anaerobic digestion, which produces biogas that can power the facility’s gas engine and generators, followed by aerobic treatment which yields the final product.

Two types of compost are generated: Grade A (compost that comes from green waste, such as yard/park trimmings, leftovers from kitchen or catering services, and wastes from markets) and Grade B (compost produced from MSW).  The plant started its operation in 2011 and when run at full capacity is able to process 750 tons of waste and produce 52 tons of Grade A compost, 377 tons of Grade B compost, liquid fertilizer which is composed of 51 tons of Grade A compost and 204 tons of Grade B compost, and 129 tons of biogas.

benefits-composting

This is a significant and commendable development in Qatar’s implementation of its solid waste management plan, which is to reduce, reuse, recycle and recover from waste, and to avoid disposing in landfills as much as possible.  However, the large influx of workers to Qatar in the coming years as the country prepares to host the World Cup in 2022 is expected to substantially increase solid waste generation and apart from its investments in facilities like the composting plant and in DSWMC in general, the government may have to tap into the efforts of organizations and communities to implement its waste management strategy.

Future Outlook

Thankfully, several organizations recognize the importance of composting in waste management and are raising awareness on its benefits.  Qatar Green Building Council (QGBC) has been actively promoting composting through its Solid Waste Interest Group.  Last year, they were one of the implementers of the Baytna project, the first Passivhaus experiment in the country.

This project entails the construction of an energy-efficient villa and a comparative study will be performed as to how the carbon footprint of this structure would compare to a conventional villa.  The occupants of the Passivhaus villa will also be made to implement a sustainable waste management system which includes composting of food waste and garden waste, which is meant to lower greenhouse gas emissions compared to landfilling.

Qatar Foundation is also currently developing an integrated waste management system for the entire Education City and the Food Services group is pushing for composting to be included as a method to treat food and other organic waste.  And many may not know this but composting can be and has been done by individuals in their own backyard and can even be done indoors with the right equipment.

Katrin Scholz-Barth, previous president of SustainableQatar, a volunteer-based organization that fosters sustainable culture through awareness, skills and knowledge, is an advocate of composting and has some great resources on how to start and maintain your own composting bin as she has been doing it herself.

A simple internet search will also reveal that producing compost at home is a relatively simple process that can be achieved with minimal tools.  At present, very few families in Qatar are producing their own compost and Scholz-Barth believes there is much room for improvement.

As part of its solid waste management plan as stated in the National Development Strategy for 2011-2016, Qatar aims to maintain domestic waste generation at 1.6 kg per capita per day.  This will probably involve encouraging greater recycling and reuse efforts and the reduction of waste from its source.

It would also be worthwhile to include programs that will promote and boost composting efforts among institutions, organizations and individuals, encouraging them with the fact that apart from its capability of significant waste diversion from landfills, composting can also be an attractive source of income.
