The Middle East and North Africa (MENA) region is highly susceptible to climate change, on account of its water scarcity, high dependence on climate-sensitive agriculture, concentration of population and economic activity in urban coastal zones, and the presence of conflict-affected areas. Moreover, the region is one of the biggest contributors to greenhouse gas emissions on account of its thriving oil and gas industry.

The world’s dependence on Middle East energy resources has caused the region to have some of the largest carbon footprints per capita worldwide. Not surprisingly, the carbon emissions from UAE are approximately 55 tons per capita, which is more than double the US per capita footprint of 22 tons per year. The MENA region is now gearing up to meet the challenge of global warming, as with the rapid growth of the carbon market. During the last few years, many MENA countries, like UAE, Qatar, Egypt and Saudi Arabia have unveiled multi-billion dollar investment plans in the cleantech sector to portray a ‘green’ image.

There is an urgent need to foster sustainable energy systems, diversify energy sources, and implement energy efficiency measures. The clean development mechanism (CDM), under the Kyoto Protocol, is one of the most important tools to support renewable energy and energy efficiency initiatives in the MENA countries. Some MENA countries have already launched ambitious sustainable energy programs while others are beginning to recognize the need to adopt improved standards of energy efficiency.

 The UAE, cognizant of its role as a major contributor to climate change, has launched several ambitious governmental initiatives aimed at reducing emissions by approximately 40 percent. Masdar, a $15 billion future energy company, will leverage the funds to produce a clean energy portfolio, which will then invest in clean energy technology across the Middle East and North African region. Egypt is the regional CDM leader with twelve projects in the UNFCCC pipeline and many more in the conceptualization phase.

The MENA region is an attractive CDM destination as it is rich in renewable energy resources and has a robust oil and gas industry. Surprisingly, very few CDM projects are taking place in MENA countries with only 22 CDM projects have been registered to date. The region accounts for only 1.5 percent of global CDM projects and only two percent of emission reduction credits. The two main challenges facing many of these projects are: weak capacity in most MENA countries for identifying, developing and implementing carbon finance projects and securing underlying finance.

Currently, there are several CDM projects in progress in Egypt, Jordan, Bahrain, Morocco, Syria and Tunisia. Many companies and consulting firms have begun to explore this now fast-developing field. One of them, the UK-based EcoSecurities, opened a regional office in Dubai. The company has offices in Bahrain and Lebanon and is planning for branches in Saudi Arabia and Qatar as well as intermediates in Egypt and Libya next year. The Masdar Company of Abu Dhabi, meanwhile, is the first local company in the region to pursue a CDM project.

The Al-Shaheen project is the first of its kind in the region and third CDM project in the petroleum industry worldwide. The Al-Shaheen oilfield has flared the associated gas since the oilfield began operations in 1994. Prior to the project activity, the facilities used 125 tons per day (tpd) of associated gas for power and heat generation, and the remaining 4,100 tpd was flared. Under the current project, total gas production after the completion of the project activity is 5,000 tpd with 2,800-3,400 tpd to be exported to Qatar Petroleum (QP); 680 tpd for on-site consumption, and only 900 tpd still to be flared. The project activity will reduce GHG emissions by approximately 2.5 million tCO2 per year and approximately 17 million tCO2 during the initial seven-year crediting period.

Potential CDM projects that can be implemented in the region may come from varied areas like sustainable energy, energy efficiency, waste management, landfill gas capture, industrial processes, biogas technology and carbon flaring. For example, the energy efficiency CDM projects in the oil and gas industry, can save millions of dollars and reduce tons of CO2 emissions. In addition, renewable energy, particularly solar and wind, holds great potential for the region, similar to biomass in Asia.

Biomass Combined Heat and Power (CHP) Systems

Combined Heat and Power (CHP) is the simultaneous generation of multiple forms of useful energy (usually mechanical and thermal) in a single, integrated system. In conventional electricity generation systems, about 35% of the energy potential contained in the fuel is converted on average into electricity, whilst the rest is lost as waste heat. CHP systems use both electricity and heat and therefore can achieve an efficiency of up to 90%.

CHP systems consist of a number of individual components—prime mover (heat engine), generator, heat recovery, and electrical interconnection—configured into an integrated whole. Prime movers for CHP units include reciprocating engines, combustion or gas turbines, steam turbines, microturbines, and fuel cells.

A typical CHP system provides:

  • Distributed generation of electrical and/or mechanical power.
  • Waste-heat recovery for heating, cooling, or process applications.
  • Seamless system integration for a variety of technologies, thermal applications, and fuel types.

The success of any biomass-fuelled CHP project is heavily dependent on the availability of a suitable biomass feedstock freely available in urban and rural areas.

Rural Resources Urban Resources
Forest residues Urban wood waste
Wood wastes Municipal solid wastes
Crop residues Agro-industrial wastes
Energy crops Food processing residues
Animal manure Sewage

Technology Options

Reciprocating or internal combustion engines (ICEs) are among the most widely used prime movers to power small electricity generators. Advantages include large variations in the size range available, fast start-up, good efficiencies under partial load efficiency, reliability, and long life.

Steam turbines are the most commonly employed prime movers for large power outputs. Steam at lower pressure is extracted from the steam turbine and used directly or is converted to other forms of thermal energy. System efficiencies can vary between 15 and 35% depending on the steam parameters.

Co-firing of biomass with coal and other fossil fuels can provide a short-term, low-risk, low-cost option for producing renewable energy while simultaneously reducing the use of fossil fuels. Biomass can typically provide between 3 and 15 percent of the input energy into the power plant. Most forms of biomass are suitable for co-firing.

Steam engines are also proven technology but suited mainly for constant speed operation in industrial environments. Steam engines are available in different sizes ranging from a few kW to more than 1 MWe.

A gas turbine system requires landfill gas, biogas, or a biomass gasifier to produce the gas for the turbine. This biogas must be carefully filtered of particulate matter to avoid damaging the blades of the gas turbine.  

Stirling engines utilize any source of heat provided that it is of sufficiently high temperature. A wide variety of heat sources can be used but the Stirling engine is particularly well-suited to biomass fuels. Stirling engines are available in the 0.5 to 150 kWe range and a number of companies are working on its further development.

A micro-turbine recovers part of the exhaust heat for preheating the combustion air and hence increases overall efficiency to around 20-30%. Several competing manufacturers are developing units in the 25-250kWe range. Advantages of micro-turbines include compact and light weight design, a fairly wide size range due to modularity, and low noise levels.

Fuel cells are electrochemical devices in which hydrogen-rich fuel produces heat and power. Hydrogen can be produced from a wide range of renewable and non-renewable sources. A future high temperature fuel cell burning biomass might be able to achieve greater than 50% efficiency.


CHP technologies are well suited for Clean Development Mechanism (CDM) and sustainable development projects, because they are, in general, socio-economically attractive and technologically mature and reliable. In developing countries, cogeneration can easily be integrated in many industries, especially agriculture and food-processing, taking advantage of the biomass residues of the production process. This has the dual benefits of lowering fuel costs and solving waste disposal issues.


Organic Waste Management

Most of the organic waste generated in developing countries is dumped into the landfills. It is a sheer waste of such biodegradable waste capable of generating energy to be sent into the landfills. There it is not only responsible for large scale green house gas emissions, but also becomes a health hazard and creates terrestrial pollution.

There are numerous places which are the sources of large amounts of food waste and hence a proper food-waste management strategy needs to be devised for them to make sure that either they are disposed off in a safe manner or utilized efficiently. These places include hotels, restaurants, malls, residential societies, college/school/office canteens, religious mass cooking places, airline caterers, food and meat processing industries and vegetable markets which generate organic waste of considerable quantum on a daily basis.

The anaerobic digestion technology is highly apt in dealing with the chronic problem of organic waste management in urban societies. Although the technology is commercially viable in the longer run, the high initial capital cost is a major hurdle towards its proliferation. The onus is on the governments to create awareness and promote such technologies in a sustainable manner. At the same time, entrepreneurs, non-governmental organizations and environmental agencies should also take inspiration from successful food waste-to-energy projects in other countries and try to set up such facilities in Indian cities and towns.

Woody Biomass Utilization and Sustainability

Harvesting practices remove only a small portion of branches and tops leaving sufficient biomass to conserve organic matter and nutrients. Moreover, the ash obtained after combustion of biomass compensates for nutrient losses by fertilizing the soil periodically in natural forests as well as fields. The impact of forest biomass utilization on the ecology and biodiversity has been found to be insignificant. Infact, forest residues are environmentally beneficial because of their potential to replace fossil fuels as an energy source.

Plantation of energy crops on abandoned agricultural land will lead to an increase in species diversity. The creation of structurally and species diverse forests helps in reducing the impacts of insects, diseases and weeds. Similarly the artificial creation of diversity is essential when genetically modified or genetically identical species are being planted. Short-rotation crops give higher yields than forests so smaller tracts are needed to produce biomass which results in the reduction of area under intensive forest management. An intelligent approach in forest management will go a long way in the realization of sustainability goals.

Improvements in agricultural practices promises to increased biomass yields, reductions in cultivation costs, and improved environmental quality. Extensive research in the fields of plant genetics, analytical techniques, remote sensing and geographic information systems (GIS) will immensely help in increasing the energy potential of biomass feedstock.

Bioenergy systems offer significant possibilities for reducing greenhouse gas emissions due to their immense potential to replace fossil fuels in energy production. Biomass reduces emissions and enhances carbon sequestration since short-rotation crops or forests established on abandoned agricultural land accumulate carbon in the soil. Bioenergy usually provides an irreversible mitigation effect by reducing carbon dioxide at source, but it may emit more carbon per unit of energy than fossil fuels unless biomass fuels are produced unsustainably.

Biomass can play a major role in reducing the reliance on fossil fuels by making use of thermo-chemical conversion technologies. In addition, the increased utilization of biomass-based fuels will be instrumental in safeguarding the environment, generation of new job opportunities, sustainable development and health improvements in rural areas. The development of efficient biomass handling technology, improvement of agro-forestry systems and establishment of small and large-scale biomass-based power plants can play a major role in rural development. Biomass energy could also aid in modernizing the agricultural economy.

A large amount of energy is expended in the cultivation and processing of crops like sugarcane, coconut, and rice which can met by utilizing energy-rich residues for electricity production. The integration of biomass-fueled gasifiers in coal-fired power stations would be advantageous in terms of improved flexibility in response to fluctuations in biomass availability and lower investment costs. The growth of the bioenergy industry can also be achieved by laying more stress on green power marketing.

Biomass Resources in Middle East and North Africa (MENA)

The major biomass producing MENA countries are Sudan, Egypt, Algeria, Yemen, Iraq, Syria and Jordan. Traditionally, biomass energy has been widely used in rural areas for domestic purposes in the MENA region. Since most of the region is arid/semi-arid, the biomass energy potential is mainly contributed by municipal solid wastes, agricultural residues and agro-industrial wastes.

Municipal solid wastes represent the best source of biomass in MENA countries. The high rate of population growth, urbanization and economic expansion in MENA region is not only accelerating consumption rates but also accelerating the generation of municipal waste.

The food industry in MENA produces a large number of organic residues and by-products that can be used as biomass energy sources. In recent decades, the fast-growing food and beverage processing industry has remarkably increased in importance in major countries in the region.

The Middle Eastern countries have strong animal population. The livestock sector, in particular sheep and goats, plays an important role in the national economy of the MENA countries. Agriculture plays an important role in the economies of most of the countries in the Middle East and North Africa. Crop residues encompasses all agricultural wastes such as bagasse, straw, stem, stalk, leaves, husk, shell, peel, pulp, stubble, etc.

Waste-to-Energy in the Middle East

The high volatility in oil prices in the recent past and the resulting turbulence in energy markets has compelled many MENA countries, especially the non-oil producers, to look for alternate sources of energy, for both economic and environmental reasons. The significance of renewable energy has been increasing rapidly worldwide due to its potential to mitigate climate change, to foster sustainable development in poor communities, and augment energy security and supply.

The Middle East is well-poised for waste-to-energy development, with its rich feedstock base in the form of municipal solid wastes, crop residues and agro-industrial wastes. The high rate of population growth, urbanization and economic expansion in the Middle East is not only accelerating consumption rates but also accelerating the generation of a wide variety of waste. Bahrain, Saudi Arabia, UAE, Qatar and Kuwait rank in the top-ten worldwide in terms of per capita waste generation. The gross urban waste generation quantity from Arab countries is estimated at more than 80 million tons annually. Open dumping is the most prevalent mode of municipal solid waste disposal in most countries.

Waste-to-energy technologies hold the potential to create renewable energy from waste matter, including municipal solid waste, industrial waste, agricultural waste, and industrial byproducts. Besides recovery of substantial energy, these technologies can lead to a substantial reduction in the overall waste quantities requiring final disposal, which can be better managed for safe disposal in a controlled manner. Waste-to-energy systems can contribute substantially to GHG mitigation through both reductions of fossil carbon emissions and long-term storage of carbon in biomass wastes. Modern waste-to-energy systems options offer significant, cost-effective and perpetual opportunities for greenhouse gas emission reductions. Additional benefits offered are employment creation in rural areas, reduction of a country’s dependency on imported energy carriers (and the related improvement of the balance of trade), better waste control, and potentially benign effects with regard to biodiversity, desertification, recreational value, etc. In summary, waste-to-energy can significantly contribute to sustainable development both in developed and less developed countries. Waste-to-energy is not only a solution to reduce the volume of waste that is and provide a supplemental energy source, but also yields a number of social benefits that cannot easily be quantified.

Biomass wastes can be efficiently converted into energy and fuels by biochemical and thermal conversion technologies, such as anaerobic digestion, gasification and pyrolysis. Waste-to-energy technologies hold the potential to create renewable energy from waste matter.  The implementation of waste-to-energy technologies as a method for safe disposal of solid and liquid biomass wastes, and as an attractive option to generate heat, power and fuels, can significantly reduce environmental impacts of wastes. In fact, energy recovery from MSW is rapidly gaining worldwide recognition as the fourth ‘R’ in sustainable waste management system – Reuse, Reduce, Recycle and Recover. A transition from conventional waste management system to one based on sustainable practices is necessary to address environmental concerns and to foster sustainable development in the region.

South Africa's Progress in Renewable Energy

South Africa, the most industrialized country in Africa, is highly dependent on conventional fuels which make it one of the largest emitters of greenhouse gases in the world. Coal provides around 75% of the fossil fuel demand and accounts for 90% of power generation in the country. A smooth transition to a low-carbon society requires diversification of energy resources to other energy forms, especially renewable energy. The country is endowed with abundant sunshine, good wind regimes and attractive biomass feedstocks which could provide sufficient means to replenish energy supplies and counter environmental degradation.

According to the Government’s White Paper on Renewable Energy Policy (2003), renewable energy projects are aimed to deliver the equivalent of 10,000 GWh by 2013, from wind, solar, biomass and hydro resources. Some of the larger projects that are under development include the Darling wind farm and the Bethlehem hydro scheme. Other projects such as landfill to gas and existing hydro-electric power stations are already making a contribution. South Africa, like other developing countries, faces the dual challenge of pursuing economic growth and environmental protection, and sustainable energy systems offer the possibility of resolving this problem.

Renewable Energy in Jordan

Jordan has been the leader in the development of renewable energy systems in the Middle East, with its tremendous renewable energy potential in the form of wind, solar, biomass and waste-to-energy. Renewable energy accounted for about 2% of the energy consumption in 2009, and the country has set ambitious targets to raise this share to 7% in 2015 and 10% in 2020. To achieve these figures, more than 1200MW of renewable energy projects are expected to be implemented in the coming decade, with emphasis on solar and wind energy. Jordan will require investments in the range of USD 1.4 – 2.1 billion within the next 10 years to realize its clean energy potential. The Government of Jordan has pledged its full support to the developmental initiatives in the renewable energy and energy efficiency sector through continuous cooperation with international partners, donors and private investors.

Waste-to-Energy Projects in India – Technical Issues

For self-sustaining combustion, there should be a heat content of at least 2500 kcal/kg (about 5000 Btu/lb). Usually below 1500 kcal/kg, it is not recommended for combustion. Indian MSW is infamous for its low heat content (770 to 1000 kcal/kg, on dry basis, sometimes as low as 600 kcal/kg), high moisture content (30 to 55 % by weight) and high inert contents (30 to 50 % by weight). It is a fact that Indian MSW is not directly suitable for incineration. Waste preparation is a must for incinerating Indian MSW. Waste should be dried; inerts removed and heat content improved to about 2500 kcal/kg.

In order to determine whether a thermal processing project is a feasible waste management alternative for any city, the following questions should be addressed:

  • Is source-segregation practiced in the target area?
  • Is the thermochemical technology approved by the MNRE and the CPCB?
  • Is there a buyer for the energy (electricity/CHP) produced by the energy recovery facility?
  • Is there strong political and public support for a WTE facility?
  • Are there enough funds to establish state-of-the-art small modular gasification / pyrolysis plant?

Elements of successful Advanced Thermal WTE Project

  • Waste segregation
  • Waste receiving and storage capability
  • Waste preparation plant
  • Gasification/pyrolysis process
  • Syngas treatment process
  • CHP / Power generation

Biomass Energy in Southeast Asia

The rapid economic growth and industrialization in Southeast Asia is characterized by a significant gap between energy supply and demand. The energy demand in the region is expected to grow rapidly in the coming years which will have a profound impact on the global energy market. In addition, the region has many locations with high population density, which makes public health vulnerable to the pollution caused by fossil fuels. Another important rationale for transition from fossil-fuel-based energy systems to renewable ones arises out of observed and projected impacts of climate change. Due to the rising share of greenhouse gas emissions from Asia, it is imperative on all Asian countries to promote sustainable energy to significantly reduce GHGs emissions and foster sustainable energy trends. Rising proportion of greenhouse gas emissions is causing large-scale ecological degradation, particularly in coastal and forest ecosystems, which may further deteriorate environmental sustainability in the region.

The reliance on conventional energy sources can be substantially reduced as the region is one of the leading producers of biomass resources in the world. The energy generating capacity of biomass-based CHP plants is comparatively much higher than other alternative energy technologies like solar, wind and geothermal energy. In addition, solar and wind projects are confined to remote rural electrification and community centres, where the required installed capacity is low. On the other hand, biomass-based cogeneration plants can generate higher capacities of electrical and heat energy that could benefit an entire township and industries in the immediate area.

Woody Biomass Conversion Technologies

There are many ways to generate electricity from biomass using thermo-chemical pathway. These include directly-fired or conventional steam approach, co-firing, pyrolysis and gasification.

1. Direct Fired or Conventional Steam Boiler

Most of the woody biomass-to-energy plants use direct-fired system or conventional steam boiler, whereby biomass feedstock is directly burned to produce steam leading to generation of electricity. In a direct-fired system, biomass is fed from the bottom of the boiler and air is supplied at the base. Hot combustion gases are passed through a heat exchanger in which water is boiled to create steam.

Biomass is dried, sized into smaller pieces and then pelletized or briquetted before firing. Pelletization is a process of reducing the bulk volume of biomass feedstock by mechanical means to improve handling and combustion characteristics of biomass. Wood pellets are normally produced from dry industrial wood waste, as e.g. shavings, sawdust and sander dust. Pelletization results in:

1. Concentration of energy in the biomass feedstock.
2. Easy handling, reduced transportation cost and hassle-free storage.
3. Low-moisture fuel with good burning characteristics.
4. Well-defined, good quality fuel for commercial and domestic use.

The processed biomass is added to a furnace or a boiler to generate heat which is then run through a turbine which drives an electrical generator. The heat generated by the exothermic process of combustion to power the generator can also be used to regulate temperature of the plant and other buildings, making the whole process much more efficient. Cogeneration of heat and electricity provides an economical option, particularly at sawmills or other sites where a source of biomass waste is already available. For example, wood waste is used to produce both electricity and steam at paper mills.

2. Co-firing

Co-firing is the simplest way to use biomass with energy systems based on fossil fuels. Small portions (upto 15%) of woody and herbaceous biomass such as poplar, willow and switch grass can be used as fuel in an existing coal power plant. Like coal, biomass is placed into the boilers and burned in such systems. The only cost associated with upgrading the system is incurred in buying a boiler capable of burning both the fuels, which is a more cost-effective than building a new plant.

The environmental benefits of adding biomass to coal includes decrease in nitrogen and sulphur oxides which are responsible for causing smog, acid rain and ozone pollution. In addition, relatively lower amount of carbon dioxide is released into the atmospheres. Co-firing provides a good platform for transition to more viable and sustainable renewable energy practices.

3. Pyrolysis

Pyrolysis offers a flexible and attractive way of converting solid biomass into an easily stored and transportable fuel, which can be successfully used for the production of heat, power and chemicals. In pyrolysis, biomass is subjected to high temperatures in the absence of oxygen resulting in the production of pyrolysis oil (or bio-oil), char or syngas which can then be used to generate electricity. The process transforms the biomass into high quality fuel without creating ash or energy directly.

Wood residues, forest residues and bagasse are important short term feed materials for pyrolysis being aplenty, low-cost and good energy source. Straw and agro residues are important in the longer term; however straw has high ash content which might cause problems in pyrolysis. Sewage sludge is a significant resource that requires new disposal methods and can be pyrolysed to give liquids.

Pyrolysis oil can offer major advantages over solid biomass and gasification due to the ease of handling, storage and combustion in an existing power station when special start-up procedures are not necessary.

4. Biomass gasification

Gasification processes convert biomass into combustible gases that ideally contain all the energy originally present in the biomass. In practice, conversion efficiencies ranging from 60% to 90% are achieved. Gasification processes can be either direct (using air or oxygen to generate heat through exothermic reactions) or indirect (transferring heat to the reactor from the outside). The gas can be burned to produce industrial or residential heat, to run engines for mechanical or electrical power, or to make synthetic fuels.

Biomass gasifiers are of two kinds – updraft and downdraft. In an updraft unit, biomass is fed in the top of the reactor and air is injected into the bottom of the fuel bed. The efficiency of updraft gasifiers ranges from 80 to 90 per cent on account of efficient counter-current heat exchange between the rising gases and descending solids. However, the tars produced by updraft gasifiers imply that the gas must be cooled before it can be used in internal combustion engines. Thus, in practical operation, updraft units are used for direct heat applications while downdraft ones are employed for operating internal combustion engines.

Large scale applications of gasifiers include comprehensive versions of the small scale updraft and downdraft technologies, and fluidized bed technologies. The superior heat and mass transfer of fluidized beds leads to relatively uniform temperatures throughout the bed, better fuel moisture utilization, and faster rate of reaction, resulting in higher throughput capabilities.
