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

Bioremediation: Fighting Pollution with Bacterial Assistance

Bioremediation is an engineering process which uses microorganisms to degrade a material. It can be used to treat contaminated media such as water, air and soil, by altering the environmental conditions to stimulate growth of microorganisms and degrade the target pollutant and enhance the quality of the media. In this age of rapid industrialization and depleting natural resources, there is an alarming need for a much effective sustainable development model and new ways to decontaminate and re-energize our surrounding land, water and air. Bioremediation provides an efficient and environment-friendly treatment compared to various other remediation technologies involving chemicals and radiation. … Continue reading

Environmental Impacts of Seawater Desalination

Desalination is a process that removes salt and minerals from seawater and turns it into a potable resource. It is extremely helpful in areas experiencing rising water demands due to water scarcity, droughts, growing populations and increased water consumption. With the ocean covering most of the Earth’s surface, seawater provides a sustainable, long-term solution to a problem that won’t soon dissipate. By 2015, 18,000 desalination plants had cropped up worldwide, producing 22,870 million gallons of fresh water per day. Experts believe desalination, coupled with future advancements in technology, could be the key to establishing drought-proof communities worldwide. A clean source … Continue reading

MBBR Technology in Wastewater Treatment

Moving bed biofilm reactor (MBBR) is a biological technology used for wastewater treatment process suitable for municipal and industrial application. Another common name is moving bed film reactor. It was invented in the 1980s. MBBR offer an economical solution for wastewater treatment. STP MBBR technology is the use of a moving bed biofilm reactor in sewage treatment plants. MBBR wastewater treatment system enables efficient results of the disposal using low energy. The technology is used to separate organic substances, nitrification and denitrification. MBBR design is made of an activated sludge aeration system. The sludge is collected on the plastic carriers … Continue reading

The Problem of CO2-Caused Acidification

“The CO2 problem” has traditionally been understood as the fact that excessive CO2 produces global warming. But near the end of the 20th century, scientists started talking about a second CO2 problem, “ocean acidification”. Ocean acidification results from the fact that about 30 percent of our CO2 emissions have been absorbed by the ocean. This absorption keeps down the warming of the atmosphere that would otherwise be produced by these emissions. Ocean acidification involves the ocean’s pH, changes in which make the water become either more alkaline or more acidic. Tests have shown that “for more than 600,000 years the … Continue reading

The Promise of Bioremediation

Ecosystems are permanently challenged with the abundant release of toxic compounds into the environment due to a wide range of anthropogenic activities. Apparently, contamination with oil spills and oily waste disposal are a major global concern since it’s extensively damaging the biodiversity, threatening the public health and has severe ecological and socioeconomic consequences. For example, in 1989, thousands metric tons spell of crude oil in Alaska, led to a massive loss in the marine life as well as several long-term environmental impact. Minor oil spills and non-point oil contamination are no less threats to public health, biodiversity and environment. Awareness of … Continue reading

Hazardous Waste Management in Qatar: Progress and Challenges

A country with an abundance of raw materials, cheap labor, and a rising demand for energy, Qatar needed to diversify its industrial sector in the 1970s. From then onwards, the use of fertilizers, petrochemicals, and gas liquefaction plants have grown exponentially. The magnitude of hazardous waste and the pollution to be produced from different streams have not been thoroughly considered, but Qatar has taken serious steps to implement commitments for sustainable development by passing laws and treaties, such as law No.4 in 1981 issuing safeguards and providing requirements for the protection of the environment, and by signing onto treaties such … Continue reading

Cleanliness is Next to Greenliness

There are usually many objectives of cleaning a home or office and the things in it. One of them is to achieve a certain level comfort and freshness while the other is to maintain the aesthetic appeal of the space around. However, when it comes to choosing the right cleaning products and technologies, it is important and beneficial to go the eco-friendly way. Many manufacturers, in a bid to reduce their carbon footprint, are striving to come up with cleaning products that are made from environmentally-friendly ingredients. Such products are not only safer or less toxic to use, but also … Continue reading

VeryNile – Keeping the Nile Alive

Over the last decade we have become increasingly alarmed at the amount of plastic in our oceans. More than 8 Million tons of it ends up out oceans every year and if we continue to pollute at this rate, there will be more trash than fish by the year 2050. By the way, there are 3.5 Trillion fishes in the ocean now. Where does all this waste come from? After analyzing waste in rivers and surrounding landscape, researchers found that most plastic waste comes from rivers; and 90% of this waste comes from only 10 river systems. One of them, … Continue reading

Nile – The Lifeline of Egypt

The Nile always played a key role in the lives of Egyptians. It made living in the desert possible, provided drinking water; it was a source of irrigation and most importantly created fertile soil that allowed for growing crops to feed the masses. The Nile also offered an ideal means of transport for goods and people thus causing development of boats and other water traveling methods. During the course of history, using the Nile for trading with other countries proved easier and safer than land. The trip from northern to southern Egypt would have been very strenuous if it wasn’t … Continue reading

The Dangers of Asbestos

The use of asbestos has been a widespread issue that continues to impact countries on a global scale. As a favored material used in buildings and construction projects throughout the 20th century, asbestos held an incredible appeal as a mineral known for its heat and fire resistant properties. For decades, this substance was synonymous with manufacturing and development. However, it was soon discovered that once asbestos was disturbed or damaged, the fibrous material could have a fatal effect on those that came into contact with it. Asbestos in the United States Despite its known dangers, asbestos continues to pose a … Continue reading
