Saudi Arabia has been witnessing rapid industrialization, high population growth rate and fast urbanization which have resulted in increased levels of pollution and waste. Solid waste management is becoming a big challenge for the government and local bodies with each passing day. With population of around 35 million, Saudi Arabia generates more than 15 million tons of solid waste per year. The per capita waste generation is estimated at 1.5 to 1.8 kg per person per day.
Solid waste generation in the three largest cities – Riyadh, Jeddah and Dammam – exceeds 6 million tons per annum which gives an indication of the magnitude of the problem faced by civic bodies. More than 75 percent of the population is concentrated in urban areas which make it necessary for the government to initiate measures to improve recycling and waste management scenario in the country.
In Saudi Arabia, municipal solid waste is collected from individual or community bins and disposed of in landfills or dumpsites. Saudi waste management system is characterized by lack of waste disposal and tipping fees. Recycling, reuse and energy recovery is still at an early stage, although they are getting increased attention. Waste sorting and recycling are driven by an active informal sector. Recycling rate ranges from 10-15%, mainly due to the presence of the informal sector which extracts paper, metals and plastics from municipal waste.
Recycling activities are mostly manual and labor intensive. Composting is also gaining increased interest in Saudi Arabia due to the high organic content of MSW (around 40%). Efforts are also underway to deploy waste-to-energy technologies in the Kingdom. All activities related to waste management are coordinated and financed by the government.
The Saudi government is aware of the critical demand for waste management solutions, and is investing heavily in solving this problem. The 2017 national budget allocated SR 54 billion for the municipal services sector, which includes water drainage and waste disposal. The Saudi government is making concerted efforts to improve recycling and waste disposal activities. Saudi visa for qualified waste management professionals will also go a long way in improving waste management situation in the country.
Solid waste management is already a significant concern for municipal governments across South Asia. It constitutes one of their largest costs and the problem is growing year on year as urban populations swell. As with all waste management experiences, we have learned lessons and can see scope for improvement.
Collection and Transportation
There are two factors which have a significant impact on the costs and viability of a waste management system as it relates to collection and transportation: first, the distance travelled between collection and disposal point; and second, the extent to which ‘wet’ kitchen waste can be kept separate from dry waste much of which can be recycled. Separating waste in this way reduces the costs of manual sorting later on, and increases the prices for recyclable materials.
In many larger towns distances become too great for door-to-door collectors to dispose waste directly at the dump site. Arrangements are made to dispose of waste at secondary storage points (large skips) provided by the municipality. However, where these are not regularly emptied, the waste is likely to be spread beyond the bins, creating a further environmental hazard.
Ideally, and if suitable land can be found, a number of smaller waste disposal sites located around a town would eliminate this problem. With significant public awareness efforts on our part, and continual daily reminders to home-owners, we were able to raise the rate of household separation to about 60%, but once these reminders became less frequent, the rate dropped rapidly back to around 25%. The problem is compounded in larger cities by the unavailability of separated secondary storage bins, so everything is mixed up again at this point anyway, despite the best efforts of householders.
If rates are to be sustained, it requires continual and on-going promotion in the long term. The cost of this has to be weighed against the financial benefit of cleaner separated waste and reduced sorting costs. Our experience in Sri Lanka shows how important a role the Local Authority can play in continuing to promote good solid waste management practices at the household level.
Home Composting
Our experience with home composting shows that complete coverage, with every household using the system, is very unlikely to be achieved. Where we have promoted it heavily and in co-operation with the Local Authority we have found the sustained use of about 65% of the bins. Even this level of coverage, however, can have an important impact on waste volumes needing to be collected and disposed of. At the same time it can provide important, organic inputs to home gardening, providing a more varied and nutritious diet for poor householders.
Waste to Compost and Waste to Energy
The variety of technologies we have demonstrated have different advantages and disadvantages. For some, maintenance is more complicated and there can be issues of clogging. For the dry-fermentation chambers, there is a need for a regular supply of fresh waste that has not already decomposed. For other systems requiring water, quite large amounts may be needed. All of these technical challenges can be overcome with good operation and maintenance practices, but need to be factored in when choosing the appropriate technology for a given location.
The major challenge for compost production has been to secure regular sales. The market for compost is seasonal, and this creates an irregular cash flow that needs to be factored in to the business model. In Bangladesh, a significant barrier has been the need for the product to be officially licensed. The requirements for product quality are exacting in order to ensure farmers are buying a product they can trust.
However, the need for on-site testing facilities may be too prescriptive, creating a barrier for smaller-scale operations of this sort. Possibly a second tier of license could be created for compost from waste which would allow sales more easily but with lower levels of guarantees for farmers.
Safe Food Production and Consumption
Community people highly welcomed the concept of safe food using organic waste generated compost. In Sri Lanka, women been practicing vertical gardening which meeting the daily consumption needs became source of extra income for the family.
Female organic fertilizer entrepreneurs in Bangladesh are growing seasonal vegetables and fruits with compost and harvesting more quality products. They sell these products with higher price in local and regional markets as this is still a niche market in the country. The safe food producers require financial and regulatory support from the government and relevant agencies on certification and quality control to raise and sustain market demand.
The concept of safe food using organic waste generated compost is picking up in South Asia
Conclusion
Solid waste management is an area that has not received the attention it deserves from policy-makers in South Asia nations. 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. If we are to meet the challenge, we will need new approaches to partnerships, and the adoption of different kinds of systems and technologies. This will require greater awareness and capacity building at the Local Authority level. If national climate or SDG targets are to be met, they will need to be localised through municipalities. Greater knowledge sharing at national and regional levels through municipal associations, regional bodies such as SAARC and regional local authority associations such as Citynet, will be an important part of this.
Practical Action’s key messages for regional and national policy makers, based on our experience in the region in the last 5 years, are about the need for:
creating new partnerships for waste collection with NGOs and the informal sector,
considering more decentralised approaches to processing and treatment, and
recognising the exciting potential for viable technologies for generating more value from waste
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?
Salman Zafar: As per Energy Statistics 2015 (refer to http://mospi.nic.in/Mospi_New/upload/Energy_stats_2015_26mar15.pdf), waste-to-energy potential in India is estimated to be 2,556 MW, of which approximately 150 MW (around 6%) has been harnessed till March 2016.
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: MSW-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.
Entrepreneurship in solid waste management can be instrumental in environment protection, decentralization, economic restructuring and job creation. Entrepreneurial opportunities in solid waste planning are available in the areas of waste collection, waste handling, waste sorting, waste storage, waste transport, waste transformation and energy recovery from waste.
Entrepreneurship begins with the generation of an idea and culminates in realization of the project objectives. Historically, the improvement of waste management services by the public sector has been hampered by lack of funds in both developed and developing nations.
Waste materials destined to be processed to generate electricity
Entrepreneurs can not only invest money in solid waste management sector, but also infuse new ideas, technologies and skills which can transform waste from being a liability into an asset. The efficiency of solid waste management increases with the involvement of entrepreneurs. Infact, it has been observed that involvement of entrepreneurs in solid waste management planning can reduce the service cost by half in Latin American cities with higher employment generation and vehicles productivity.
Entrepreneurial ventures in solid waste management can range from a one-man project to a mega-scale project involving thousands of skilled and unskilled workers. It has been observed that solid waste management is a labour-intensive process with tremendous potential to generate new jobs, depending on the type of project and the level of creativity. The major areas of entrepreneurial involvement include waste collection, transportation, reuse and recycling, upcycling and power generation.
Basic safety equipment is essential to minimize health risks to informal recycling sector.
According to the World Bank, municipalities in developing countries typically spend 20 to 50 per cent of their annual budget on solid waste management, but only 40 to 70 per cent of solid waste is collected and less than 50 per cent of the population has access to municipal waste collection services.
Solid waste planning is an integral component of urban development as it contributes to public health, resource conservation and environment protection. Scientific disposal of domestic waste can prevent environmental degradation and harmful public health impacts while recycling can help in conservation of precious natural resources and energy.
Entrepreneurial activities in solid waste collection can not only increase waste collection efficiency but also improve waste management services for the marginalized sections of the society. An excellent example is the case of Nigeria-based Wecyclers which is aiming to building a low-cost waste collection infrastructure in Lagos by offering cheap and convenient domestic waste recycling services using a fleet of cargo bikes.
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.
Burning of municipal wastes is a common practice in Nigeria
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.
Some countries have achieved considerable success in solid waste management. But the rest of the world is grappling to deal with its wastes. In these places, improper management of solid waste continues to impact public health of entire communities and cities; pollute local water, air and land resources; contribute to climate change and ocean plastic pollution; hinder climate change adaptation; and accelerate depletion of forests and mines.
Compared to solid waste management, we can consider that the world has achieved significant success in providing other basic necessities like food, drinking water, energy and economic opportunities. Managing solid wastes properly can help improve the above services further.
Composting of organic waste can help nurture crops and result in a better agricultural yield. Reducing landfilling and building sanitary landfills will reduce ground and surface water pollution which can help provide cleaner drinking water. Energy recovery from non-recyclable wastes can satiate significant portion of a city’s energy requirement.
Inclusive waste management where informal waste recyclers are involved can provide an enormous economic opportunity to the marginalized urban poor. Additionally, a good solid waste management plan with cost recovery mechanisms can free tax payers money for other issues. In the case of India, sustainable solid waste management in 2011 would have provided
9.6 million tons of compost that could have resulted in a better agricultural yield
energy equivalent to 58 million barrels of oil from non-recyclable wastes
6.7 million tons of secondary raw materials to industries in the form of recyclable materials and livelihood to the urban poor
Solid waste management until now has only been a social responsibility of the corporate world or one of the services to be provided by the municipality and a non-priority for national governments. However, in Mumbai, the improperly managed wastes generate 22,000 tons of toxic pollutants like particulate matter, carbon monoxide, nitrous and sulfur oxides in addition to 10,000 grams of carcinogenic dioxins and furans every year. These numbers are only for the city of Mumbai. This is the case in cities all across the developing world. There are numerous examples where groundwater is polluted by heavy metals and organic contaminants due to solid waste landfills.
Solid waste management expenditure of above $ 1 billion per year competes with education, poverty, security and other sustainable initiatives in New York City. Fossil fuels for above 500,000 truck trips covering hundreds of miles are required to transport NYC’s waste to landfills outside the city and state. Similarly, New Delhi spends more than half of its entire municipal budget on solid waste management, while it is desperate for investments and maintenance of roads, buildings, and other infrastructure.
Solid waste management is not just a corporate social responsibility or a non-priority service anymore. Improper waste management is a public health and environmental crisis, economic loss, operational inefficiency and political and public awareness failure. Integrated solid waste management can be a nation building exercise for healthier and wealthier communities. Therefore, it needs global attention to arrive at solutions which span across such a wide range of issues.
China is the world’s largest waste generator, producing as much as 175 million tons of waste every year. With a current population surpassing 1.37 billion and exponential trends in waste output expected to continue, it is estimated that China’s cities will need to develop an additional hundreds of landfills and waste-to-energy plants to tackle the growing waste management crisis.
China’s three primary methods for municipal waste management are landfills, incineration, and composting. Nevertheless, the poor standards and conditions they operate in have made waste management facilities generally inefficient and unsustainable. For example, discharge of leachate into the soil and water bodies is a common feature of landfills in China. Although incineration is considered to be better than landfills and have grown in popularity over the years, high levels of toxic emissions have made MSW incineration plants a cause of concern for public health and environment protection.
Prevalent Issues
Salman Zafar, a renowned waste management, waste-to-energy and bioenergy expert was interviewed to discuss waste opportunities in China. As Mr. Zafar commented on the current problems with these three primary methods of waste management used by most developing countries, he said, “Landfills in developing countries, like China and India, are synonymous with huge waste dumps which are characterized by rotting waste, spontaneous fires, toxic emissions and presence of rag-pickers, birds, animals and insects etc.” Similarly, he commented that as cities are expanding rapidly worldwide, it is becoming increasingly difficult to find land for siting new landfills.
On incineration, Zafar asserted that this type of waste management method has also become a controversial issue due to emission concerns and high technology costs, especially in developing countries. Many developers try to cut down costs by going for less efficient air pollution control systems”. Mr. Zafar’s words are evident in the concerns reflected in much of the data that waste management practices in China are often poorly monitored and fraudulent, for which data on emission controls and environmental protection is often elusive.
Similarly, given that management of MSW involves the collection, transportation, treatment and disposal of waste, Zafar explains why composting has also such a small number relative to landfills for countries like China. He says, “Composting is a difficult proposition for developing countries due to absence of source-segregation. Organic fraction of MSW is usually mixed with all sorts of waste including plastics, metals, healthcare wastes and industrial waste which results in poor quality of compost and a real risk of introduction of heavy metals into agricultural soils.”
Given that China’s recycling sector has not yet developed to match market opportunities, even current treatment of MSW calls for the need of professionalization and institutionalization of the secondary materials industry.
While MSW availability is not an issue associated with the potential of the resource given its dispersion throughout the country and its exponential increase throughout, around 50 percent of the studies analyzed stated concerns for the high moisture content and low caloric value of waste in China, making it unattractive for WTE processes.
Talking about how this issue can be dealt with, Mr. Zafar commented that a plausible option to increase the calorific value of MSW is to mix it with agricultural residues or wood wastes. Thus, the biomass resources identified in most of the studies as having the greatest potential are not only valuable individually but can also be processed together for further benefits.
Top Challenges
Among the major challenges on the other hand, were insufficient or elusive data, poor infrastructure, informal waste collection systems and the lack of laws and regulations in China for the industry. Other challenges included market risk, the lack of economic incentives and the high costs associated with biomass technologies. Nevertheless, given that the most recurring challenges cited across the data were related to infrastructure and laws and regulations, it is evident that China’s biomass policy is in extreme need of reform.
China’s unsustainable management of waste and its underutilized potential of MSW feedstock for energy and fuel production need urgent policy reform for the industry to develop. Like Mr. Zafar says, “Sustainable waste management demands an integration of waste reduction, waste reuse, waste recycling, and energy recovery from waste and landfilling. It is essential that China implements an integrated solid waste management strategy to tackle the growing waste crisis”.
Future Perspectives
China’s government will play a key role in this integrated solid waste management strategy. Besides increased cooperation efforts between the national government and local governments to encourage investments in solid waste management from the private sector and foster domestic recycling practices, first, there is a clear need to establish specialized regulatory agencies (beyond the responsibilities of the State Environmental Protection Administration and the Ministry of Commerce) that can provide clearer operating standards for current WTE facilities (like sanitary landfills and incinerators) as well as improve the supervision of them.
It is essential that China implements an integrated solid waste management strategy to tackle the growing waste crisis
Without clear legal responsibility assigned to specialized agencies, pollutant emissions and regulations related to waste volumes and operating conditions may continue to be disregarded. Similarly, better regulation in MSW management for efficient waste collection and separation is needed to incentivize recycling at the individual level by local residents in every city. Recycling after all is complementary to waste-to-energy, and like Salman Zafar explains, countries with the highest recycling rates also have the best MSW to energy systems (like Germany and Sweden).
Nevertheless, without a market for reused materials, recycling will take longer to become a common practice in China. As Chinese authorities will not be able to stop the waste stream from growing but can reduce the rate of growth, the government’s role in promoting waste management for energy production and recovery is of extreme importance.
Out of all the measures that are necessary in addressing India’s impending waste management crisis, the most efficient will be changes at the national policy and planning level. It is well-known among the small but growing waste management sector that urban India will hit rock bottom due to improper waste management.
Unfortunately, they think such a crisis is required to bring about policy changes, as they generally tend to happen only after the damage has been done. This attitude is unfortunate because it indicates a lack of or failed effort from the sector to change policy, and also the level of India’s planning and preparedness.
An average of 32,000 people will be added to urban India every day, continuously, until 2021. This number is a warning, considering how India’s waste management infrastructure went berserk trying to deal with just 25,000 new urban Indians during the last decade. The scale of urbanization in India and around the world is unprecedented with planetary consequences to Earth’s limited material and energy resources, and its natural balance.
Rate of increase in access to sanitation infrastructure generally lags behind the rate of urbanization by 33% around the world; however, the lack of planning and impromptu piecemeal responses to waste management issues observed in India might indicate a much wider gap. This means urban Indians will have to wait longer than an average urban citizen of our world for access to proper waste management infrastructure.
The clear trend in the outbreak of epidemic and public protests around India is that they are happening in the biggest cities in their respective regions. Kolkata, Bengaluru, Thiruvananthapuram, and Srinagar are capitals of their respective states, and Coimbatore is the second largest city in Tamil Nadu. However, long term national level plans to improve waste management in India do not exist and guidance offered to urban local bodies is meager.
Apart from the Jawaharlal Nehru National Urban Renewal Mission (JnNURM), there has been no national level effort required to address the problem. Even though JnNURM was phenomenal in stimulating the industry and local governments, it was not enough to address the scale and extent of the problem. This is because of JnNURM is not a long term waste management financing program, sorts of which are required to tackle issues like solid waste management.
Are Cities Hands-tied or is Change Possible?
In the short term, municipal corporations have their hands tied and will not be able to deliver solutions immediately. They face the task of realizing waste management facilities inside or near cities while none of their citizens want them near their residences. Officials of Hyderabad’s municipal corporation have been conducting interviews with locals for about eight years now for a new landfill site, to no avail.
In spite of the mounting pressure, most corporations will not be able to close the dumpsites that they are currently using. This might not be the good news for which local residents could be waiting, but, it is important that bureaucrats, municipal officials and politicians be clear about it. Residents near Vellalore dump protested and blocked roads leading to the site because Coimbatore municipal officials repeatedly failed to fulfill their promises after every landfill fire incident.
Due to lack of existing alternatives, other than diverting waste fractionally by increasing informal recycling sector’s role, closing existing landfills would mean finding new sites. Finding new landfills in and around cities is nearly impossible because of the track record of dumpsite operations and maintenance in India and the Not in My Backyard (NIMBY) phenomenon.
However, the corporations can and should take measures to reduce landfill fires and open burning, and control pollution due to leachate and odor and vector nuisance. This will provide much needed relief to adjacent communities and give the corporations time to plan better. While navigating through an issue as sensitive this, it is of the utmost importance that they work closely with the community by increasing clarity and transparency.
Municipal officials at the meeting repeatedly stressed the issue of scarcity of land for waste disposal, which led to overflowing dumpsites and waste treatment facilities receiving more waste than what they were designed for. Most municipal officials are of the sense that a magic solution is right around the corner which will turn all of their city’s waste into electricity or fuel oil or gas, or into recycled products. While such conversion is technologically possible with infinite energy and financial sources, that is not the reality.
Despite their inability to properly manage wastes, the majority of municipal officials consider waste as “wealth” when approached by private partners. Therefore, a significant portion of officials expect royalty from private investments without sharing business risk.
Financing of solid waste management projects can be pretty overwhelming for the city government, especially if the government see it as a critical part of the service they should render to the citizen and if the citizen also hold it as a basis for measuring the performance of the government and using it as one of the conditions for re-election.
The increasing cost of waste disposal is a cause of major concern in developing nations
Solid waste management entails different aspects. Generally speaking, waste management consists of pre-collection, collection, transportation, storage, treatment, and disposal. The modern hierarchy of waste management includes prevention, minimization, reuse, recycling, energy recovery, and disposal.
All these aspects require proper funding in rendering a good waste management service to the society. As citizens, we hardly give any thought to the different aspects and what it takes to ensure it is carried out efficiently and effectively.
Financing Options for Solid Waste Management
There are four different options for financing of solid waste management projects. The option chosen will be dependent on various factors. The chief factor will be “what is the end goal of providing waste management service to citizen” and this is to be determined by the city government. Therefore, we say finance option is directly related to waste management goal of a city or State.
Public Financing
This primarily involves funding of waste management service entirely by the government through budgetary allocation. The government determines how it will generate the cash for service and this can be through taxation or redistribution of funds generated from other sources like sales of city natural resources or combination of various sources of funds.
In developing countries, this is generally inefficient due to the corruption within the government and lack of proper waste management capabilities in most instances. The government might decide to charge a service fee or not.
Private Financing
This involves infusing funds from the private sector into waste management service and also overseeing day-to-day running of the service. However, the hired company will charge a service fee which will be determined by calculating the amount of invested funds, operating cost, and profit envisaged. This will be spread over a period of time.
This financing option can deliver optimal result in providing waste management service but the private sector needs to be checked in order not to set a high fee that will end up scaring citizens which might lead to citizen abhorring the service.
Public-Private Partnership (PPP)
This is a special type of arrangement which brings together the government and private sector in providing funds and management capabilities for the delivery of waste management service.
All things being equal, this arrangement is best because the government will be able to regulate and have a say in how the service should be delivered especially as it relates to the setting of service fees which might be difficult in the solely private financing option. The PPP can equally be extended to be a Joint Venture (usually termed as Institutional PPP).

Donors and Grants
This funding mechanism is dependent on the interest of the donor organization. While it is a good way to develop a city’s waste management infrastructure, attracting and utilizing grants is solely reliant on what the donor considers as important. Hence, it might be difficult for a city government to dictate how the funds should be distributed among the various aspect of waste management.

However, this type of financing can be combined with a PPP arrangement to cater for a specific waste management aspect that is in tandem with the interest of the donor and can be part of the city government contribution to the PPP.
Conclusion
In conclusion, waste management financing is quite dynamic just like many other services and infrastructure provided by a city government and the best option for financing the provision of waste management service can only be made after appropriate due diligence and consultation with relevant stakeholders has been made and observed.
