Desalination – A Better Choice for MENA

Water scarcity is a major problem in many parts of the world affecting quality of life, the environment, industry, and the economies of developing nations. The Middle East and North Africa (MENA) region is considered as one of the most water-scarce regions of the world. Large scale water management problems are already apparent in the region. While the MENA region’s population is growing steadily, per capita water availability is expected to fall by more than 40-50% by the year 2050. Also, climate change is likely to affect weather and precipitation patterns, and the consequences of which may force the MENA … Continue reading

Environmental Impact of Olive Oil Processing Wastes

More commonly known for its popular culinary and medicinal benefits, olive cultivation and olive oil production are a part of the local heritage and rural economy throughout the North African and Mediterranean regions. In 2012, an estimated 2,903,676 tons of olive oil was produced worldwide, the largest olive oil producers being Spain, Italy, and Greece followed by Turkey and Tunisia and to a lesser extent Portugal, Morocco and Algeria. Within the European Union’s olive sector alone, there are roughly 2.5 million producers, who make up roughly one-third of all EU farmers. The olive oil industry offers valuable opportunities to farmers in … Continue reading

Use of Sewage Sludge in Cement Industry

The MENA region produces huge quantity of municipal wastewater which represents a serious problem due to its high treatment costs and risk to environment, human health and marine life. The per capita wastewater generation rate in the region is estimated at 80-200 litres per day. Sewage generation across the region is rising by an astonishing rate of 25 percent every year. Municipal wastewater treatment plants in MENA produce large amounts of sludge whose disposal is a cause of major concern. For example, Kuwait has 6 wastewater treatment plants, with combined capacity of treating 12,000m³ of municipal wastewater per day, which produce around … Continue reading

Role of Agricultural Sector in Harnessing Renewable Energy

The continuous rise in fossil energy prices, combined with climate change concerns and progress in renewable energy sector, has catalyzed interest in clean energy systems across the MENA region, especially in the Mediterranean. The Mediterranean region has abundant renewable resources, such as wind, solar, and biomass, which makes it a fertile zone for renewable energy developments. The agricultural sector has played a key role in the progress of renewable energy sector around the world as it provides large areas where renewable energy projects are built and is also the predominant feedstock source for biomass energy projects. For example, agricultural sector … Continue reading

Medical Waste Management in MENA

Healthcare sector in MENA region is growing at a very rapid pace, which in turn has led to tremendous increase in the quantity of medical waste generation by hospitals, clinics and other establishments. According to a recent Ministry of State for Environmental Affairs report, Egypt generated 28,300 tons of hazardous medical wastes in 2010. In the GCC region, more than 150 tons of medical waste is generated in GCC countries every day. Saudi Arabia leads the pack with daily healthcare waste generation of more than 80 tons. These figures are indicative of the magnitude of the problem faced by municipal authorities in … Continue reading

Rationale for Solar Energy in MENA

The world is rife with news snippets concerning the development of solar power. The sun provides an infinite source of energy that takes off the burden on the renewable sources for power generation. In doing so, there are increased chances of conserving the limited energy reserves. Already about 50% of the earth’s natural resources are in use. If this usage rate continues, we will run out of finite sources in no time. For instance, there is only enough oil left for the coming 46.2 years. Luckily, the development of solar energy serves as the light at the end of the … Continue reading

On Recycling of Fluorescent Bulbs

All fluorescent bulbs contain mercury. In fact, the standard fluorescent bulb has about 20 milligrams of mercury. It is clear that these lamps must be managed properly to protect human health and the environment. The risk of leaving mercury deposits in landfill is high; therefore, recycling seems the most conscientious and environmentally safe recourse. A comprehensive fluorescent bulb recycling strategy will not only help in environment protection but can also promote new business growth and job opportunities. An analysis of the lighting industry shows a trend shifting from the usage of incandescent bulbs to fluorescent bulbs and LEDs. Incandescent bulbs use more energy, … Continue reading

Strategic Water Management in the 21st Century

The water crisis in the 21st century is related to many economic, political, and social factors. A lot of people believe that the main reason behind the crisis lies in poor strategic water management and not in the lack of resources. It is estimated that in a few years almost half of the world’s population will live in water-stressed areas, such as MENA, where inhabitants will struggle to gain access to clean water. Saving the Environment It is no secret that the environmental pollution is affecting every aspect of our lives. But when it comes to water resources, the problem … Continue reading

The Fight Against Desertification

As the global population crosses 7 billion, the pressure on land has increased exponentially in recent decades. Food security, habitat and livelihood are the buzz words these days. The paradox is that despite ever-increasing demand for land, more than 10 million hectares of arable land turns into desert every year. The major factors responsible for desertification are deforestation, over-grazing, unsustainable cultivation methods and poor irrigation practices, apart from climate change. According to Mr. Luc Gnacadja, executive secretary of the United Nations Convention to Combat Desertification, “Land degradation is a global phenomenon, with 78 percent of the degrading land taking place in … Continue reading

Wastes as Energy Resource

The tremendous increase in the quantum and diversity of waste materials generated by human activities has focused the spotlight on waste management options. Waste generation rates are affected by standards of living, degree of industrialization and population density. Generally, the greater the economic prosperity and the higher percentage of urban population, the greater the amount of waste produced. A good example are the oil-rich GCC nations who are counted among the world's most prolific per capita waste generators. Reduction in the volume and mass of wastes is a crucial issue due to limited availability of final disposal sites in the … Continue reading

Renewable Energy in GCC: Need for a Holistic Approach

The importance of renewable energy sources in the energy portfolio of any country is well known, especially in the context of energy security and impacts on climate change. The growing quest for renewable energy and energy efficiency in the Gulf Cooperation Council (GCC) countries has been seen by many as both – a compulsion to complement the rising energy demand, and as an economic strength that helps them in carrying forward the clean energy initiatives from technology development to large scale deployment of projects from Abu Dhabi to Riyadh. Current Scenario The promotion of renewable energy (RE) is becoming an … Continue reading

The Consequences of Ocean Acidification

The relentless rise in the percentage of atmospheric carbon dioxide since the Industrial Revolution is a well-known fact. Carbon dioxide is considered as one of the key players among the greenhouse gases that has contributed the most towards global warming, the current hot topic among environmentalists, scientists and even politicians. Another key issue is increasing being discussed nowadays is Ocean Acidification. Ocean acidification is an ongoing change in the chemistry of the ocean caused primarily by the ocean’s absorption of carbon dioxide from the atmosphere. What is Ocean Acidification Around 1/4th of the carbon dioxide released into the atmosphere via … Continue reading
