With population of approximately 1.75 million, waste management is one of the most serious challenges confronting the local authorities. The daily solid waste generation across Gaza is more than 1300 tons which is characterized by per capita waste generation of 0.35 to 1.0 kg. Scarcity of waste disposal sites coupled with huge increase in waste generation is leading to serious environmental and human health impacts on the population.
The severity of the crisis is a direct consequence of continuing blockade by Israeli Occupation Forces and lack of financial assistance from international donor. Israeli Occupation Forces deliberately destroyed most of the sewage infrastructure in the Gaza Strip, during 2008-2009 Gaza War inflicting heavy damage to sewage pipes, water tanks, wastewater treatment plants etc.
There are three landfills in Gaza Strip – one each in southern and central part of Gaza and one in Gaza governorate. In addition, there are numerous unregulated dumpsites scattered across rural and urban areas which are not fenced, lined or monitored. Around 52% of the MSW stream is made up of organic wastes.
Domestic, industrial and medical wastes are often dumped near cities and villages or burned and disposed of in unregulated disposal sites which cause soil, air and water pollution, leading to health hazards and ecological damage. The physical damage caused to Gaza’s infrastructure by repeated Israeli aggression has been a major deterred in putting forward a workable solid waste management strategy in the Strip.
The sewage disposal problem is assuming alarming proportions. The Gaza Strip’s sewage service networks cover most areas, except for Khan Yunis and its eastern villages where only 40% of the governorate is covered. There are only three sewage water treatment stations in Gaza Strip – in Beit Lahia, Gaza city and Rafah – which are unable to cope with the increasing population growth rate. The total quantity of produced sewage water is estimated at 45 million m3 per annum, in addition to 3000 cubic meters of raw sewage sludge discharged from Gaza Strip directly into the sea every day. Sewage water discharge points are concentrated on the beaches of Gaza city, Al Shate’ refugee camp and Deir El Balah.
The continuous discharge of highly contaminated sewage water from Gaza Strip in the Mediterranean shores is causing considerable damage to marine life in the area. The beaches of Gaza City are highly polluted by raw sewage. In addition, groundwater composition in Gaza Strip is marked by high salinity and nitrate content which may be attributed to unregulated disposal of solid and liquid wastes from domestic, industrial and agricultural sources. The prevalent waste management scenario demands immediate intervention of international donors, environmental agencies and regional governments in order to prevent the situation from assuming catastrophic proportions.
Waste management in the SAARC countries has occasionally been raised as an area for regional co-operation. It fits in with other more pressing regional concerns such as environmental degradation, food safety, power generation, poverty alleviation and trans-boundary technology transfer. The Dhaka Declaration on Waste Management of 2004, for example, recognises the environmental imperative to promote more effective waste management systems ‘with special attention to addressing the needs of the poor’.
Similarly, the SAARC action plan on Climate Change of 2008 listed waste management as an area for nationally appropriate mitigation actions where regional sharing of best practices could be useful. The 2010 convention on co-operation on the environment, also included waste management among a list of 19 areas for the exchange of best practices and knowledge, and transfer of eco-friendly technology. However, these commitments have rarely turned into concerted action.
Effectively tackling the growing waste management crisis has not proved easy for most municipalities. Their capacity to cope has not kept pace with the increasing quantities of waste generated, and yet waste management can be one of the biggest costs of municipal budgets. Often they are able to collect waste only from limited areas of their towns. For the South Asia region, waste collection rates are on average 65%, with wide variations between towns.
At the same time, there is often a very active recycling system through waste pickers and the informal sector, involving large numbers of poor people. Large schemes to recycle, separate and produce useful end-products such as compost have often run into problems if they relied too heavily on donor inputs. Once these were phased out they failed to generate sufficient income from sales to be sustainable.

Two global agreements signed in 2015 may help to raise the profile and stimulate greater action on solid waste management. First, the Sustainable Development Goals which include a goal focused on cities and sustainable urban development. Within this, target 11.6 is to “by 2030, reduce the adverse per capita environmental impact of cities, including by paying special attention to air quality and municipal and other waste management”. This is the first time a global agreement of this sort has included commitments on waste management. Second, the Paris Climate Agreement, with a number of South Asian countries including better management of urban waste as part of their Intended Nationally Determined Contribution.
Solid waste management is already a significant concern for municipal governments across the South Asian region. It constitutes one of their largest costs and the problem is growing year on year as urban populations swell. And yet it is an area that has not received the attention it deserves from policy-makers. There are signs this may change, with its inclusion in the SDGs and in many INDCs which are the basis of the Paris Climate Agreement.
India’s waste-to-energy sector, which kicked off in 1987, is still searching for a successful role model, even after tens of millions of dollars of investment. In recent years, many ambitious waste-to-energy projects have been established or are being planned in different parts of the country, and it is hoped that things will brighten up in the coming years. Salman Zafar, CEO of BioEnergy Consult, talks to Power Today magazine on India’s tryst with waste-to-energy and highlights major challenges and obstacles in making waste-to-energy a success story in India.
Power Today: What are the challenges that the Waste to Energy sector faces in the current scenario where there is a rejuvenated interest in clean energy? Do you think the buzz around solar and wind power has relegated the Waste to Energy sector to the back benches?
Salman Zafar: India’s experience with waste-to-energy has been lackluster until now. The progress of waste-to-energy sector in India is hampered by multiples issues including
poor quality of municipal waste,
high capital and O&M costs of waste-to-energy systems,
lack of indigenous technology,
lack of successful projects and failure of several ambitious projects,
lack of coordination between municipalities, state and central governments,
heavy reliance on government subsidies,
difficulties in obtaining long-term Power Purchase Agreements (PPAs) with state electricity boards (SEBs)
lukewarm response of banks and financial institutions and (9) weak supply chain.
Waste-to-energy is different from solar (or wind) as it essentially aims to reduce the colossal amount of solid wastes accumulating in cities and towns all over India. In addition to managing wastes, waste-to-energy has the added advantage of producing power which can be used to meet rapidly increasing energy requirements of urban India. In my opinion, waste-to-energy sector has attracted renewed interest in the last couple of years due to Swachch Bharat Mission, though government’s heavy focus on solar power has impacted the development of waste-to-energy as well as biomass energy sectors.
Power Today: India has a Waste to Energy potential of 17,000 MW, of which only around 1,365 MW has been realised so far. How much growth do you expect in the sector?
The progress of waste-to-energy sector in India is dependent on resolution of MSW supply chain issues, better understanding of waste management practices, lowering of technology costs and flexible financial model. For the next two years, I am anticipating an increase of around 75-100 MW of installed capacity across India.
Power Today: On the technological front, what kinds of advancements are happening in the sector?
Salman Zafar: Nowadays, advanced thermal technologies like MBT, thermal depolymerisation, gasification, pyrolysis and plasma gasification are hogging limelight, mainly due to better energy efficiency, high conversion rates and less emissions. Incineration is still the most popular waste-to-energy technology, though there are serious emission concerns in developing countries as many project developers try to cut down costs by going for less efficient air pollution control system.
Power Today: What according to you, is the general sentiment towards setting up of Waste to Energy plants? Do you get enough cooperation from municipal bodies, since setting up of plants involves land acquisition and capital expenditure?
Salman Zafar: Waste-to-energy projects, be it in India or any other developing country, is plagued by NIMBY (not-in-my-backyard) effect. The general attitude towards waste-to-energy is that of indifference resulting in lukewarm public participation and community engagement in such projects.
Government should setup dedicated waste-to-energy research centres to develop lost-cost and low-tech waste to energy solutions
Lack of cooperation from municipalities is a major factor in sluggish growth of waste-to-energy sector in India. It has been observed that sometimes municipal officials connive with local politicians and ‘garbage mafia’ to create hurdles in waste collection and waste transport. Supply of poor quality feedstock to waste-to-energy plants by municipal bodies has led to failure of several high-profile projects, such as 6 MW MSW-to-biogas project in Lucknow, which was shut down within a year of commissioning due to waste quality issues.
Power Today: Do you think that government policies are in tandem when it comes to enabling this segment? What policies need to be changed, evolved or adopted to boost this sector?
Salman Zafar: A successful waste management strategy demands an integrated approach where recycling and waste-to-energy are given due importance in government policies. Government should strive to setup a dedicated waste-to-energy research centre to develop a lost-cost and low-tech solution to harness clean energy from millions of tons of waste generated in India.
The government is planning many waste-to-energy projects in different cities in the coming years which may help in easing the waste situation to a certain extent. However, government policies should be inclined towards inclusive waste management, whereby the informal recycling community is not robbed of its livelihood due to waste-to-energy projects.
Government should also try to create favourable policies for establishment of decentralized waste-to-energy plants as big projects are a logistical nightmare and more prone to failure than small-to-medium scale venture.

Iraq is one of the most populous Arab countries with population exceeding 32 million. Rapid economic growth, high population growth, increasing individual income and sectarian conflicts have led to worsening problem of solid waste management problem in Iraq. Iraq generates around 31,000 tons of solid waste every day with per capita waste generation exceeding 1.4 kg per day. Baghdad alone produces more than 1.5 million tons of solid wastes each year.
Rapid increase in waste generation is putting tremendous strain on Iraqi waste handling infrastructure which have heavily damaged after decades of conflict and mismanagement. In the absence of modern and efficient waste handling and waste disposal infrastructure most of the wastes are disposed in unregulated landfills across Iraq, with little or no concern for both human health and environment. Spontaneous fires, groundwater contamination, surface water pollution and large-scale greenhouse gas emissions have been the hallmarks of Iraqi landfills.
The National Solid Waste Management Plan (NSWMP) for Iraq was developed in 2007 by collaboration of international waste management specialist. The plan contains the recommendations for development and which explains the background for decisions.
The plan states that Iraq will build 33 engineered landfills with the capacity of 600 million m3 in all of the 18 governorates in Iraq by 2027. In addition to constructing landfills the plan also focuses on the collection and transportation, disposable, recycling and reuses systems. Environment education was also taken into consideration to ensure provision of educational system which supports the participation of both communities and individuals in waste management in Iraq.
Besides Iraqi national waste management plan, the Iraqi ministry of environment started in 2008 its own comprehensive development program which is part of the ministry of environment efforts to improve environmental situation in Iraq. Ministry of Municipalities and Public Work, in collaboration with international agencies like UN Habitat, USAID, UNICEF and EU, are developing and implementing solid waste management master plans in several Iraqi governorates including Kirkuk, Anbar, Basra, Dohuk, Erbil, Sulaimaniya and Thi Qar.
Kirkuk was the first city in Iraq to benefit from solid waste management program when foreign forces initiated a solid waste management program for the city in 2005 to find an environmentally safe solution to the city’s garbage collection and disposal dilemma. As a result the first environmentally engineered and constructed landfill in Iraq was introduced in Kirkuk In February 2007. The 48-acre site is located 10 miles south of Kirkuk, with an expected lifespan of 10–12 years and meets both the U.S. Environmental Protection Agency and European Union Landfill Directive standards.
The Iraqi city of Basra also benefited from international aid with the completion of the first landfill that is compliant with international environmental standards has been completed. Basra solid waste management program developed by UNICEF will not only restore efficient waste collection systems in the city but will also create informal “recycling schools” that will help in spreading environmental awareness in in the city’s society by launching a campaign to educate the public about effective waste disposal practices.
In addition, Basra city program plans to establish a regional treatment and disposal facility and initiate street sweeping crews. Basrah city waste management program is part of the UNICEF program supported by the European Union to develop Iraq’s water and sanitation sector.
Erbil’s solid waste management master plan has also been developed by UNICEF with funding from the European Union. Recently a contract was signed by the Kurdistan Region’s Ministry of Municipalities and Tourism and a Canadian company to recycle the city’s garbage which will involve the construction of two recycling plants in the eastern and western outskirts of Erbil.
UNICEF has also developed a master plan to improve the management of solid waste in Dohuk Governorate which has been finalized in June 2011. Solid waste management master plans for Anbar, Sulaimaniya and Thi Qar governorates are also a part of UNICEF and EU efforts to attaining Iraq’s Millennium Development Goal targets of ensuring environmental sustainability by 2015.
Even though all of the effort by the international organizations are at local level and still not enough to solve solid waste management problem in Iraq, however these initiatives have been able to provide a much needed information regarding the size of the issue and valuable lessened learned used later by the Iraqi government to develop the Iraqi national waste management plan with the support of organizations such as UN Habitat, UNDG Iraq Trust Fund and USAID. The Iraqi national waste management plan is expected to ease the solid waste management problem in Iraq in the near future.
