Solid waste management is one of the major environmental problems threatening the Kingdom of Morocco. More than 5 million tons of solid waste is generated across the country with annual waste generation growth rate touching 3 percent. The proper disposal of municipal solid waste in Morocco is exemplified by major deficiencies such as lack of proper infrastructure and suitable funding in areas outside of major cities.
According to the World Bank, it was reported that before a recent reform in 2008 “only 70 percent of urban wastes was collected and less than 10 percent of collected waste was being disposed of in an environmentally and socially acceptable manner. There were 300 uncontrolled dumpsites, and about 3,500 waste-pickers, of which 10 percent were children, were living on and around these open dumpsites.”
It is not uncommon to see trash burning as a means of solid waste disposal in Morocco. Currently, the municipal waste stream, including hazardous wastes, is disposed of in a reckless and unsustainable manner which has major effects on public health and the environment. The lack of waste management infrastructure leads to burning of trash as a form of inexpensive waste disposal. Unfortunately, the major health effects of burning trash are either widely unknown or grossly under-estimated to the vast majority of the population in Morocco.
The good news about the future of Morocco’s MSW management is that the World Bank has allocated $271.3 million to the Moroccan government to develop a municipal waste management plan. The plan’s details include restoring around 80 landfill sites, improving trash pickup services, and increasing recycling by 20%, all by the year 2020. While this reform is expected to do wonders for the urban population one can only hope the benefits of this reform trickle down to the 43% of the Moroccan population living in rural areas, like those who are living in my village.
Needless to say, even with Morocco’s movement toward a safer and more environmentally friendly MSW management system there is still an enormous population of people including children and the elderly who this reform will overlook. Until more is done, including funding initiatives and an increase in education, these people will continue to be exposed to hazardous living conditions because of unsuitable funding, infrastructure, policies and education.
The palm oil industry is particularly involved in the development of sustainability standards. Driven by growing global demand, palm oil production has expanded rapidly in the last few years. Palm oil is the most widely consumed vegetable oil in the world, and its popularity has grown even more with the emergence of new market opportunities in the biofuels sector, in addition to its traditional food and oleochemical uses.
This strong growth has unquestionably contributed to the economic development of the main producer countries – Indonesia and Malaysia – which account for 87% of global production. Palm oil cultivation provides income for many smallholders, whose produce accounts for around 40% of world palm oil output.
Environmental and Socio-economic Concerns
However, the expansion of palm oil cultivation has also generated serious environmental concerns. It results in tropical deforestation and thus has a major impact on biodiversity loss, with the decline of emblematic species such as orangutan in Southeast Asia. It contributes to climate change through deforestation, but also through the conversion of peatlands, which are of vital importance in soil carbon sequestration.
The huge forest and bush fires in recent years in Indonesia which are associated with clearing lands for agricultural or forestry plantations caused severe air pollution and public health problems across the sub-region. In addition, industrial plantations are sometimes responsible for polluting waterways, into which chemical inputs and processing plant waste are dumped.
Moreover, this expansion has sometimes resulted in social abuses and human rights violations, in the form of land grabbing by plantation companies at the expense of local and indigenous communities or of the exploitation of plantation workers.
Sustainability Standards in Oil Palm Industry
Condemnation of these abuses by NGOs and growing consumer awareness of the adverse impacts of the expansion of palm oil plantation have driven the development of sustainability standards. Such standards are aimed at transforming production practices in order to mitigate their adverse environmental and social effects.
The expansion of palm oil cultivation in Southeast Asia has also generated serious environmental concerns.
In 2001, representatives of the food processing and distribution sector launched a dialogue with WWF and plantation companies, leading to the creation in 2004 of the first voluntary sustainability standard in the sector, the Roundtable on Sustainable Palm Oil (RSPO).
There are now 2.41 million hectares of RSPO-certified plantations, while sustainable palm oil accounted for 20% of world trade in this product. Meanwhile, several other initiatives proposing a vision of palm oil sustainability have emerged, positioning themselves as either a complement or an alternative to RSPO.
New Challenges to Overcome
The development of these initiatives demonstrates the growing awareness among producers, the industry and the public authorities of the need to transform the sector to enable it to contribute to the Sustainable Development Goals (SDGs). But this proliferation of sustainability standards itself poses new challenges, even though the environmental and social problems that motivated their emergence remain unresolved.
At the institutional level, the proliferation of sustainability initiatives since the creation of RSPO reflects a real fragmentation of the regulatory framework. This proliferation also raises the question of the articulation of these voluntary standards with the public regulations and national sustainability standards that producer countries have adopted.
Finally, measures to ensure the sustainability of palm oil cultivation need to bolster their credibility by guaranteeing better inclusion of the millions of smallholders, and by contributing in an effective, measurable way to mitigating the adverse social and environmental impacts of growth in palm oil cultivation. In this field, the role of collaborative and multidisciplinary research in providing strong evidence-based impact evaluation of standards is crucial.
The impact of human activities on the environment is rapidly changing. One such activity gaining much attention is waste disposal. A lot of waste products go to landfills despite constituting a reasonable fraction of organic matter, such as paper materials, food wastes, and pet droppings.
The new preferred way to dispose of organic waste is composting. Composting refers to the process through which materials biodegrade. It is a means by which organic waste can be safely recycled. Composting can be effectively done with compost systems.
Take note that this process of waste disposal is still in its early stages, especially when adopted in homes. Still, here are 7 benefits of composting:
1. Improved Soil Quality
Composted materials become humus, a known nutrient-rich constituent of soil. The newly formed humus replenishes soil nutrients and improves water retention in loose soil. Thus, soil quality considerably improves as a result of composting.
Composted materials are also rich in fungi and bacteria. These microbes prevent insect infestation and suppress weed growth. With these nutrient draining agents out of the way, your soil quality dramatically improves, too.
2. Saves Time and Money
It is a waste of time and money when a yard being cultivated does not experience normal growth, nor does it yield the expected harvest. Fortunately, you can save money and time in the long term with composting practices. This is possible because of the compost’s ability to fight insect infestation, weed growth, and to replenish the soil of lost nutrients.
The three nutrients that are sought in chemical fertilizers, Nitrogen, Phosphorus, and Potassium (NPK), are made available by humus. This directly saves you the cost of purchasing fertilizers. Without the presence of compost, farmers need to spend a lot of money to buy pesticides and weed killers.
3. Environment Friendliness
Composting is an environmentally friendly option compared to landfills. Landfills are currently the most common destination for organic waste. In landfills, organic waste cannot decay properly, so they generate a specific greenhouse gas called methane.
Methane is known to cause harmful effects on the environment – similar to that of carbon dioxide but even more dangerous. The more organic waste ends up in landfills, the more methane gas that is produced.
Composting solves this problem in a whiff by reducing the amount of methane produced while organic matter decays. Composting allows carbon to be retained in the soil, which lowers the carbon footprint caused by decaying matter.
The ability of compost to bypass the incineration of yard waste also makes it a preferred option for organic waste in yards.
4. Improved Human Health
There are several ways for composting to indirectly enhance human health. The reduction of greenhouse gas emissions, as mentioned above, by composting is not only good for the environment but also for people – a reduction of greenhouse gas means a healthier environment to live in.
Organic food production credited to composting also improves human health in significant ways. It reduces the number of chemicals from fertilizers and pesticides that end up in meals, translating to healthier humans.
5. Higher Agricultural Yield
A higher yield of crops is very important to farmers. Through its ability to increase soil quality, composting achieves a higher return in agricultural products. More plant yield accounts for more plants to be sold, which also means more money to be made.
Soil quality also translates to the quality of the food which is produced. Food produced from high-quality, organic soil is free from all toxins from chemical fertilizers and pesticides.
6. Reduced Erosion
Erosion is harmful to the soil because it makes soil matter and nutrients to be washed away. This is compounded by the fact that soils are loose.
Compost averts erosion by remedying the existing structure of the soil. It further prevents erosion by:
Aiding water infiltration in the soil structure.
Aiding water retention, thereby slowing runoff and loss of soil matter.
Allows for quicker vegetation growth.
7. Aids Biodiversity
Microorganisms present in the soil, such as bacteria, fungi, and protozoa, will cause the decay of organic material. Their presence is important because they aid soil aeration. Soil aeration on its own accelerates the composting process, making nutrients available in their usable state as quickly as possible.
Other organisms that are present in composted soil include worms and beneficial insects. All these aids the process of plant growth.
Composting is a sustainable and environmentally friendly way to dispose of organic waste. It is particularly important even now as the world struggles with creating solutions to waste disposal.
Composting results in better soil quality. It is also a process that saves them time and money of farmers. Humans can benefit from composting through improved health. There is a higher yield of farm produce as a result of composting. Erosion is significantly reduced, and biodiversity is achieved in the soil through composting.
Solid waste management situation in Pakistan is a matter of grave concern as more than 5 million people to die each year due to waste-related diseases. In Pakistan roughly 20 million tons of solid waste is generated annually, with annual growth rate of about 2.4 percent. Karachi, largest city in the country, generates more than 9,000 tons of municipal waste daily. All major cities, be it Islamabad, Lahore or Peshawar, are facing enormous challenges in tackling the problem of urban waste. The root factors for the worsening garbage problem in Pakistan are lack of urban planning, outdated infrastructure, lack of public awareness and endemic corruption.
Being the 6th most populated country in the world; there is a lot of consumerism and with it a great deal of waste being produced. Like other developing countries, waste management sector in Pakistan is plagued by a wide variety of social, cultural, legislative and economic issues. In the country, more waste is being produced than the number of facilities available to manage it. Some of the major problems are:
There is no proper waste collection system
Waste is dumped on the streets
Different types of waste are not collected separately
There are no controlled sanitary landfill sites. Opening burning is common.
Citizens are not aware of the relationship between reckless waste disposal and resulting environmental and public health problems
As a result of these problems, waste is accumulating and building up on roadsides, canals, and other common areas and burning trash is common, causing hazardous toxins to be exposed thereby threatening human and environmental health. Among the already few landfill sites that are present, even fewer are in operation. Even within Pakistan’s capital, Islamabad, there are no permanent landfills to be found.
The waste on the roads allows for an ideal environment for various flies to thrive which effects both human health and the health of the environment for other species. The poor solid waste management in Pakistan has caused numerous diseases and environmental problems to rise.
Waste Management Situation in Lahore
In Lahore, the capital of Punjab and the second largest city in Pakistan, there are currently no controlled waste disposal facilities are formal recycling systems, though roughly 27% of waste (by weight) is recycled through the informal sector, Lahore does not have very high performing governmental management in the waste management situation. Instead, the City District Government Lahore established the Lahore Waste Management Company and left the responsibility of the Solid Waste Management in Lahore to them. Beginning in 2011, Lahore Waste Management Company strives to develop a system of SWM that ensures productive collection, recovery, transportation, treatment and disposal of the waste in Lahore.
Lahore Waste Management Company (LWMC) has over 10,000 field workers involved in waste collection and disposal. Though the LWMC is working in phases, 100% collection rates are not seen yet. Lahore currently only has three disposal sites which are no more than dumps, where illegal dumping and trash burning is common. However, there is some resource recovery taking place. It is estimated that 27% of dry recyclables are informally recycled within the city. Additionally a composting plant converts 8% of waste into compost.
In general, the governance over the Waste Management in Lahore is hardly present. Though there are current projects and plans taking place, by the Lahore Waste Management Company for example, in order to achieve a productive and sustainable system in the city it is necessary for all service providers (formal, private, and informal) to take part in decisions and actions.
Current Activities and Projects
According to the United Nations Environment Program, there are six current activities and plans taking place towards an efficient waste management system. These current activities are as follows:
Solid Waste Management Guidelines (draft) prepared with the support of Japan International Cooperation Agency (JICA), Japan.
Converting waste agricultural biomass into energy/ material source – project by UNEP, IETC Japan.
North Sindh Urban Services Corporation Limited (NSUSC) – Assisting the district government in design and treatment of water supply, sanitation and solid waste management
The URBAN UNIT, Urban Sector Policy & Management Unit P & D Department, Punjab. Conducting different seminars on awareness of waste water, sanitation & solid waste management etc.
Lahore Compost (Pvt.) Ltd. only dealing with the organic waste with the cooperation of city district government Lahore, Pakistan. The company is registered as a CDM project with UNFCCC.
Different NGOs are involved at small scale for solid waste collection, and recycling.
Additionally, in November 2013 a German company, agreed to invest in the installation of a 100 megawatt power plant which generates energy from waste from Lahore. Progress is being made on the country’s first scientific waste disposal site in Lakhodair. With this in mind, the Lahore Waste Management Company considered other possible technologies for their Waste-to-Energy project. They opened up applications for international companies to hire as the official consultant for LWMC and their project. The results of the feasibility study results showed that the power plant has the potential to process 1035 tons of municipal waste daily, and generate 5.50 megawatt electricity daily.
The Way Forward
Although SWM policies do exist, the levels at which they are implemented and enforced lack as a result of the governmental institutions lacking resources and equipment. These institutions are primarily led by public sector workers and politicians who are not necessarily the most informed on waste management. For improvements in municipal solid waste management, it is necessary for experts to become involved and assist in the environmental governance.
Due to the multiple factors contributing to the solid waste accumulation, the problem has become so large it is beyond the capacity of municipalities. The former director of the Pakistan Council of Scientific and Industrial Research, Dr. Mirza Arshad Ali Beg, stated, “The highly mismanaged municipal solid waste disposal system in Pakistan cannot be attributed to the absence of an appropriate technology for disposal but to the fact that the system has a lot of responsibility but no authority.” Laws and enforcement need to be revised and implemented. The responsibility for future change is in the hands of both the government, and the citizens.
Waste practices in the Pakistan need to be improved. This can start with awareness to the public of the health and environment impacts that dumped and exposed waste causes. It is imperative for the greater public to become environmentally educated, have a change in attitude and take action.
In recent years, the world has seen significant economic progress, which greatly relied on energy fueled by coal and petroleum among others. With the continuously growing demand for energy, it is a fact that these energy sources may be depleted in the near future. Apart from this, there are several other reasons why humankind already needs to find alternative energy sources.
It is a known fact that different manufacturing processes and human activities, such as using vehicles, cause pollution in the atmosphere by releasing carbon dioxide. Carbon dioxide traps heat in the earth, and this phenomenon is known as global warming. Global warming has several harmful impacts such as stronger and more frequent storms, as well as drought and heat waves. Renewable energy sources such as wind, solar, geothermal, hydroelectric, and biomass to name a few, all generate minimal global warming emissions.
Wind power, for instance, has the capability to supply energy with a significantly lower emission compared to burning coal for fuel. This is the reason why wind energyis more beneficial compared to carbon-intensive energy sources. Still, the emissions generated by wind power are even lower compared to other renewable energy sources such as solar, geothermal, and hydroelectric power sources. This makes a huge potential for wind power to sustain the world’s energy demands, while preserving the environment.
It goes without saying that the pollution caused by burning coal and fuel not only has an environmental impact, but it also has a significant effect on public health. Various diseases and ailments can be attributed to pollution, which usually affects the respiratory tract. Contaminated water also causes various bacterial infections. Wind power, solar energy, and hydroelectric systems have the capability to generate electricity without emitting air pollutants. Additionally, wind and solar energy sources do not need water to operate, thereby, eliminating the probability of polluting water resources. Clean air and water that is free from pollutants, will have a significant positive impact on public health.
Constant Energy Source
While coal and fossil fuels are on the threshold of depletion, renewable energy sources are inexhaustible. Wind can be a constant energy source and no matter how high the demand for energy will be, the wind will not be depleted. In the same manner, as long as the sun shines bright on earth, there will always be an abundant solar energy source. Fast-moving water that can be translated into hydroelectric energy, the earth’s heat that can be converted into a geothermal power source, as well as abundant plant matter that can be used as biomass, can all be constantly replenished. These can never be fully exhausted no matter how great the energy demand will be. The utilization of a combination of each of these energy sources will prove to be even more beneficial. Additionally, with its continued use, there will no longer be a need for combustible energy sources.
Lower Energy Costs
The cost of electricity continues to be a burden on the earth’s greater population. The use of renewable energy sources to light up the earth is considerably cheaper and inexpensive compared to the cost of burning fossil fuels for electricity and other energy needs. Apart from a cheaper cost, renewable energy sources can help stabilize to cost of energy in the long run, with an unlimited supply being able to cater to greater demand. While it cannot be denied that setting up clean energy technologies comes with a cost, it can be noted that the cost of its operation is significantly lower. Conversely, the cost of coal and fossil fuels for energy consumption fluctuates over a wide range and is greatly affected by the economic and political conditions of its country of origin.
Fossil fuel technologies, often, revolve around the capitalistic market. Hence, the use of combustible fuels is often linked to unfavorable labor conditions, and even child labor and slavery. On the other hand, the use of renewable energy sources provides decent jobs, contributing to several economic benefits. For instance, workers are needed to install and maintain solar panels. In the same manner, wind farms employ technicians for maintenance. Thus, jobs are created directly in parallel with the unit of energy produced. This means that more jobs will be produced if more renewable energy sources are utilized.
Clean energy sources, specifically wind and solar power, are less susceptible to large-scale failures. The reason behind this is that both wind and solar power both employ distributed and modular systems. This means that electricity will not be totally cut off in instances of extreme weather conditions because the energy sources powering up the electricity is spread out over a wider geographical area. In the same manner, there will still be a continuous supply of energy even if certain equipment in the entire system is damaged because clean fuel technologies are made up of modules such as a number of individual wind turbines or solar panels.
With all the reasons to check out alternative energy sources, it still holds true that there remain several barriers that hinder the full implementation of renewable energy technologies. Some of these challenges are capital costs because of reliability misconceptions, as well as a difficult market entry due to an unequal playing field. Because renewable energy sources are cheap to operate, the bulk of the expenses in its implementation is building the technology. Thereby, the rate of return for capitalists and investors in the market entails a longer waiting period. Adding to this barrier is the hidden political agenda that most governments need to overcome.
Economic progress and advancement in technology are not at all bad. On the contrary, it has brought forth a lot of benefits such as cures for ailments and diseases, resources for deep-sea or space explorations, as well as meaningful collaboration and communication. However, this progress came with a price, and unfortunately, it’s the world’s energy resources that are on the brink of exhaustion. Hence, mitigation has been already necessary and finding alternative energy sources is just one of the probable solutions.
Kuwait, being one of the richest countries, is among the highest per capita waste generators in the world. Each year more than 2 million tons of solid waste is generated in the tiny Arab nation. High standards of living and rapid economic growth has been a major factor behind very high per capita waste generation of 1.4 to 1.5 kg per day.
Waste Disposal Method
The prevalent solid waste management method in Kuwait is landfill burial. Despite being a small country, Kuwait has astonishingly high number of landfills. There are 18 landfills, of which 14 sites are closed and 4 sites are still in operation. These landfills act as dumpsites, rather than engineered landfills.
Menace of Landfills
Infact, landfill sites in Kuwait are notorious for causing severe public health and environmental issues. Besides piling up huge amounts of garbage, landfill sites generate huge amount of toxic gases (methane, carbon dioxide etc) and plagued by spontaneous fires. Due to fast paced urban development, residential areas have expanded to the edges of landfill sites thus causing grave danger to public health.
The total land area of Kuwait is around 17,820 sq. km, out of which more than 18 sq. km is occupied by landfills. Area of the landfill sites ranges from tens to hundreds of hectares with waste deposition depth varying from 3 to 30 meters.
All kind of wastes, including municipal wastes, food wastes, industrial wastes, construction and demolition debris etc are dumped at these sites. Infact, about 90 percent of the domestic waste is sent to landfills which imply that more landfills will be required to tackle rapidly increasing volumes of solid wastes.
Most of the landfill sites have been closed for more than 20 years due to operational problems and proximity to new residential, commercial and industrial areas. These sites include Sulaibiyah, Kabed, Al Qurain, Shuaiba, Jleeb AI Shuyoukh, West Yarmouk, AI Wafra among others. Migration of leachate beyond landfill site boundaries is a frequent problem noticed across Kuwait. Groundwater contamination has emerged as a serious problem because groundwater occurs at shallow depths throughout the country.
The major landfill sites operated by municipality for solid waste disposal are Jleeb AI Shuyoukh, Sulaibiyah and Al-Qurain. The Qurain landfill, with area of 1 sq. km, was used for dumping of municipal solid waste and construction materials from 1975 until 1985 with total volume of dumped waste being 5 million m3.
The Sulaibiyah landfill site received more than 500 tons of waste per day from 1980 to 2000 with area spanning 3 sq. km. Jleeb AI Shuyoukh, largest landfill site in Kuwait with area exceeding 6 sq. km, received 2500 tons per day of household and industrial waste between 1970 and 1993. Around 20 million m3 of wastes was dumped in this facility during its operational period.
Over the years, most of the dumpsites in Kuwait have been surrounded by residential and commercial areas due to urban development over the years. Uncontrolled dumpsites were managed by poorly-trained staff resulting in transformation of dumpsites in breeding grounds for pathogens, toxic gases and spontaneous fires.
Most of the landfill sites have been forced to close, much before achieving their capacities, because of improper disposal methods and concerns related to public health and environment. Due to fast-paced industrial development and urban expansion, some of the landfills are located on the edges of residential, as is the case of Jleeb Al-Shuyoukh and Al-Qurain sites, endangering the lives of hundreds of thousands of people.
Waste disposal methods vary from city to city, state to state and region to region. It equally depends on the kind and type of waste generated. In determining the disposal method that a city or nation should adopt, some factors like type, kind, quantity, frequency, and forms of waste need to be considered.
For the purpose of this article, we will look at the three common waste disposal methods in Africa and the kind of waste they accept.
This is the crudest means of disposing of waste and it is mostly practiced in rural areas, semi-urban settlements, and undeveloped urban areas. For open dumping or open burning, every type and form of waste (including household waste, hazardous wastes, tires, batteries, chemicals) is dumped in an open area within a community or outside different homes in a community and same being set on fire after a number of days or when the waste generator or community feels it should be burnt.
There is no gainsaying that the negative health and environmental impact of such practice are huge only if the propagators know better.
This is apparent in most States in Nigeria, if not all and some cities in Africa like Mozambique, Ghana, Kenya, Cameroon, to mention but a few. It is a method of disposing of all kinds of waste in a designated area of land by waste collectors and it is usually controlled by the State or City Government.
Opening burning of trash is a common practice across Africa
Controlled dumps are commonly found in urban areas and because they are managed by the government, some dumps do have certain features of a landfill like tenure of usage, basic record keeping, waste covering, etc. Many cities in Nigeria confuse the practice of controlled dumping as landfilling but this not so because a landfill involves engineering design, planning, and operation.
A sanitary landfill is arguably the most desired waste management option in reducing or eliminating public health hazards and environmental pollution. The landfill is the final disposal site for all forms and types of waste after the recyclable materials must have been separated for other usages and other biodegradables have been extracted from the waste for use as compost, heat, or energy; or after incineration. These extractions can be done at household level or Material Recovery Facilities (MRFs) operated by the government or private individuals.
As desirable as a landfill is, so many factors need to be put into consideration in its siting and operation plus it requires a huge investment in construction and operation. Some of these factors include but not limited to distance from the residential area, proximity to water bodies, water-table level of the area the landfill is to be sited, earth material availability, and access road.
