In recent years the Kingdom has made significant strides in waste management by promoting recycling initiatives.

Saudi Arabia’s Ministry of Environment, Water and Agriculture has unveiled a plan to recycle up to 95 percent of the country’s waste — a move it claims will contribute SR120 billion ($31.99 billion) to gross domestic product, according to SPA (Saudi Press Agency).

Recycling not only helps reduce the amount of waste that ends up in landfills but also conserves natural resources and reduces pollution. 

By separating recyclable materials like paper, plastic, glass, and metal from general waste, we can give them a second life in which they are processed into new products.

In addition to environmental benefits, recycling creates job opportunities within the local economy. It stimulates innovation and encourages businesses to develop sustainable practices that support long-term economic growth.

Incorporating the practice of composting into your daily routine can have a significant impact on reducing organic waste and promoting sustainability. 

By separating food scraps and other biodegradable materials from your regular trash, you not only divert waste from landfills but also create nutrient-rich soil that can be used to nourish plants in your garden or community. 

Composting is a simple yet effective way to close the loop on the natural cycle of decomposition, turning what would otherwise be considered garbage into a valuable resource.

What is happening now in Saudi is very encouraging, but we still have a lot to do to reach the country’s goals to reach zero waste. 

According to Saudi Arabia’s National Center for Waste Management, the financial cost of environmental degradation caused by solid waste in the Kingdom in 2021 was estimated at $1.3 billion. 

Nearly half of Saudi Arabia’s total waste comes from three cities: 21 percent from Riyadh, 14 percent from Jeddah, and 8 percent from Dammam.

By making conscious choices to recycle everyday items instead of throwing them away, we are actively contributing to a cleaner environment for future generations.

“SIRC has developed a robust recycling infrastructure that includes collection centers and material recovery facilities,” Ziyad Al-Shiha, CEO of the Saudi Investment Recycling Company, announced in January. 

“These facilities are equipped with advanced technologies to sort, process, and recycle different types of waste materials.”

Recycling waste in Saudi Arabia helps promote sustainability in several ways. It reduces environmental impact by cutting the amount of waste that ends up in landfills, which in turn decreases pollution and greenhouse gas emissions.

It helps conserve natural resources such as water, energy, and raw materials by reusing materials instead of extracting new ones.

Furthermore, the recycling industry in Saudi Arabia has the potential to create new jobs in waste collection, sorting, and processing, contributing to economic growth.

Proper waste management, including recycling, also helps protect natural habitats and wildlife by reducing pollution and the destruction of ecosystems.

By making conscious choices to recycle everyday items instead of throwing them away, we are actively contributing to a cleaner environment for future generations. 

So let us all do our part by incorporating recycling habits into our daily lives. Remember — every little bit counts when it comes to preserving our planet for a better tomorrow.

What to know about sudden rebel gains in Syria’s 13-year war and why it matters

What to know about sudden rebel gains in Syria’s 13-year war and why it matters
  • It was the first opposition attack on Aleppo since 2016, when an air campaign by Russian warplanes helped Syrian President Bashar Assad retake the northwestern city
  • The roughly 30 percent of the country not under Assad is controlled by a range of opposition forces and foreign troops, including Turkish and US forces and their allies

WASHINGTON: The 13-year civil war in Syria has roared back into prominence with a surprise rebel offensive on Aleppo, one of Syria’s largest cities and an ancient business hub. The push is among the rebels’ strongest in years in a war whose destabilizing effects have rippled far beyond the country’s borders.
It was the first opposition attack on Aleppo since 2016, when a brutal air campaign by Russian warplanes helped Syrian President Bashar Assad retake the northwestern city. Intervention by Russia, Iran and Lebanon's Hezbollah militia and other groups has allowed Assad to remain in power, within the 70 percent of Syria under his control.
The surge in fighting has raised the prospect of another violent front reopening in the Middle East, at a time when US-backed Israel is fighting Hamas in Gaza and Hezbollah in Lebanon.
Robert Ford, the last-serving US ambassador to Syria, pointed to months of Israeli strikes on Syrian and Hezbollah targets in the area, and to Israel’s ceasefire with Hezbollah in Lebanon this week, as factors providing Syria’s rebels with the opportunity to advance.
Here’s a look at some of the key aspects of the new fighting:
Why does the fighting at Aleppo matter?
Assad has been at war with opposition forces seeking his overthrow for 13 years, a conflict that’s killed an estimated half-million people. Some 6.8 million Syrians have fled the country, a refugee flow that helped change the political map in Europe by fueling anti-immigrant far-right movements.
The roughly 30 percent of the country not under Assad is controlled by a range of opposition forces and foreign troops. The US has about 900 troops in northeast Syria, far from Aleppo, to guard against a resurgence by the Daesh group. Both the US and Israel conduct occasional strikes in

 

Syria against government forces and Iran-allied militias. Turkiye has forces in Syria as well, and has influence with the broad alliance of opposition forces storming Aleppo.
Coming after years with few sizeable changes in territory between Syria’s warring parties, the fighting “has the potential to be really quite, quite consequential and potentially game-changing,” if Syrian government forces prove unable to hold their ground, said Charles Lister, a longtime Syria analyst with the US-based Middle East Institute. Risks include if Daesh fighters see it as an opening, Lister said.
Ford said the fighting in Aleppo would become more broadly destabilizing if it drew Russia and Turkiye — each with its own interests to protect in Syria — into direct heavy fighting against each other. 

The US and UN have long designated the opposition force leading the attack at Aleppo — Hayat Tahrir Al-Sham, known by its initials HTS — as a terrorist organization.
Its leader, Abu Mohammed Al-Golani, emerged as the leader of Al-Qaeda’s Syria branch in 2011, in the first months of Syria’s war. His fight was an unwelcome intervention to many in Syria’s opposition, who hoped to keep the fight against Assad’s brutal rule untainted by violent extremism.
Golani early on claimed responsibility for deadly bombings, pledged to attack Western forces and sent religious police to enforce modest dress by women.
Golani has sought to remake himself in recent years. He renounced his Al-Qaeda ties in 2016. He’s disbanded his religious police force, cracked down on extremist groups in his territory, and portrayed himself as a protector of other religions. That includes last year allowing the first Christian Mass in the city of Idlib in years.
What’s the history of Aleppo in the war?
At the crossroads of trade routes and empires for thousands of years, Aleppo is one of the centers of commerce and culture in the Middle East.
Aleppo was home to 2.3 million people before the war. Rebels seized the east side of the city in 2012, and it became the proudest symbol of the advance of armed opposition factions.
In 2016, government forces backed by Russian airstrikes laid siege to the city. Russian shells, missiles and crude barrel bombs — fuel canisters or other containers loaded with explosives and metal — methodically leveled neighborhoods. Starving and under siege, rebels surrendered Aleppo that year.
The Russian military’s entry was the turning point in the war, allowing Assad to stay on in the territory he held.
This year, Israeli airstrikes in Aleppo have hit Hezbollah weapons depots and Syrian forces, among other targets, according to an independent monitoring group. Israel rarely acknowledges strikes at Aleppo and other government-held areas of Syria.

Syrian authorities closed Aleppo airport and canceled all flights, military source says

AMMAN: Syrian authorities closed Aleppo airport and canceled all flights, a military source told Reuters early on Saturday as Syrian rebels opposed to President Bashar Assad said on Friday they had reached the heart of the northern city of Aleppo.

Syria was promised extra Russian military aid to help the army thwart a takeover by the rebels opposed to President Bashar al-Assad, of the northwestern Aleppo province, two Syrian military sources told Reuters on Saturday.
Damascus expects new Russian military hardware to start arriving at Russia's Hmeimim airbase near Syria's coastal city of Latakia in the next 72 hours, the sources added.

How researchers in Saudi Arabia are turning desalination waste into valuable resources

How researchers in Saudi Arabia are turning desalination waste into valuable resources
  • Industry experts are working on technology to recover minerals from the highly saline waste liquid produced from desalination.
  • Brine, a byproduct from turning sea water into fresh water, can also be repurposed for energy production, KAUST professor says

RIYADH: Saudi Arabia has established itself as a global leader in the rapidly advancing water desalination market, doubling its production capacity, while developing new technology to repurpose the harmful byproduct of the process — brine.

While desalination is effective for achieving water sustainability, producing drinking water from sea water in arid regions, it leaves behind a highly concentrated saline fluid. If this brine is disposed of back into the sea without treatment, it poses a potential danger to  marine ecosystems.

Simply put, brine is highly concentrated seawater that contains contaminants, including chemicals used during the desalination process.

“The chemicals should be all neutralized,” said Noreddine Ghaffour, a research professor at the Water Desalination and Reuse Center at King Abdullah University of Science and Technology (KAUST).

He told Arab News that “there is no reason to dump chemicals into the sea, because they are all negatively affecting marine life, including chlorine and antiscalants.”

Water desalination scientists in Saudi Arabia have developed technologies to neutralize chemicals in brine before discharge and to disperse salt over a radius of up to 2 km when reintroduced into the sea.

Ghaffour, who was granted Saudi citizenship for his work and expertise on desalination, said that researchers and industry experts believe the future of the process is in recovering minerals, while treating the brine and achieving zero liquid discharge.

While around 70 percent of Earth is covered in water, only 2.5 percent of it is fresh, of which 1 percent is easily accessible, according to the National Geographic website.

Water desalination separates salt ions from sea water to make it safe for consumption. Salinity levels vary by body of water; for example, the Red Sea has 40 grams of salt per liter, while the Arabian Gulf’s salinity is 45 grams per liter.

The three main water desalination technologies employed in Saudi Arabia are: multi-stage flash distillation, a thermal process using evaporation and condensation; multiple-effect distillation, which uses electrical energy to break down water ions; and reverse osmosis, which separates water molecules through a semipermeable membrane.

All three technologies produce brine, but reverse osmosis plants generate lower quantities compared with the other two methods.

Reverse osmosis, according to Ghaffour, uses a method called membrane separation, where osmotic pressure is overcome by a semipermeable membrane that filters out salt ions, allowing only water molecules to pass through.

Ghaffour explained that although the semipermeable membrane effectively filters out about 99 percent of salts, some still manage to pass through, producing brine.

Moreover, osmotic pressure — the force applied to a solution to prevent a solvent from passing through a semipermeable membrane — requires a lot of electrical energy.

“Electricity is one of the most expensive energy forms… the main problem with (reverse osmosis) is that we do this under pressure,” the KAUST professor said.

He added: “The more salt, the higher the osmotic pressure. In order to pass only water molecules through the membrane, we need to apply a pressure which is higher than the osmotic pressure.

“And the osmotic pressure in Red Sea water, for instance, is 30 bar… so we need a pressure higher than 30 bar, which is a very high pressure.”

He also explained that “recovery” refers to “how much water we recover from the sea,” adding that “if the recovery is 50 percent, this means that salt contents are doubled.”

Ghaffour said selecting the correct location for a desalination plant is highly important. Authorities must choose sites with a reliable water intake that will not disrupt marine ecosystems or impact densely populated areas.

According to the UN Environment Programme, unless waste water is properly treated and dispersed, it may form a dense plume of toxic brine, which can degrade coastal and marine ecosystems. 

Increased salinity and temperature can reduce dissolved oxygen levels and contribute to the formation of “dead zones” — areas where few marine species can survive.

Ghaffour said that while brine is bad for the environment, it has not caused significant global environmental harm. Over the past 30 to 40 years, Saudi Arabia and the Gulf region have experienced few negative side-effects from the desalination process, he said.

Concern over waste water from desalination returning to the sea at a higher temperature is less of an issue with the reverse osmosis method, Ghaffour said. “We have the same temperature as sea water, maybe one degree more, which is affordable.”

Researchers are determined to achieve zero liquid discharge, which involves treating brine until only solids remain. However, this process also concentrates all the salts in the same place.

To remove salt ions from brine, a complex and costly process called mineral recovery is used.

The challenge in mineral recovery lies in the fact that high-value minerals, such as lithium, rubidium, and uranium, are present in brine at very low concentrations. 

To make the process efficient and economically viable, further technological advancements are needed. 

Currently, “there are no technologies to handle this huge volume,” Ghaffour said. “We are talking about huge volumes of water, like 1 million tons of water (recovered) every day, it’s higher than a river.”

Several technologies have been developed for mineral recovery on a smaller scale. One method involves chemical treatments that precipitate different salts in stages, starting with calcium carbonate and ending with lithium.

Another mineral recovery method involves the use of ion exchange membranes or absorbents designed to capture specific minerals, such as lithium.

One of the largest areas of current research is the magnesium hydroxide family, particularly for its applications in the cement and concrete industry. 

Saudi Arabia is already using nanofiltration technology to produce magnesium from magnesium-rich waters, with the next step being the extraction of magnesium hydroxide for cement production.

Expensive and critical minerals like rubidium — which costs around $3,000 per kilo — as well as uranium and lithium, are of great interest, but are costly to extract due to their low concentrations, requiring significantly more energy in the process. 

From a commercial perspective, businesses prefer to purchase lithium from produced water — a byproduct of oil and gas production — rather than from brine. 

Brine can also be repurposed to enhance the efficiency of the desalination process. Due to its high osmotic potential, brine can be used for energy production.

Ghaffour said that several companies are utilizing reverse electrodialysis to generate energy, which is then used to power the reverse osmosis process.

In addition, to achieve a circular carbon economy, reverse electrodialysis can be combined with brine dilution for mineral recovery, allowing part of the brine to be reused in an efficient closed-loop system.

“This is what I call a seawater factory,” Ghaffour said. “We take seawater and we produce everything from seawater without polluting back. 

“Many experts are saying that in the future, desalinated water, which is what we need most, will itself be a byproduct, because we will have so many more valuable products from the sea. Then this desalinated water will be just one of the byproducts.”

However, he believes that turning this vision into reality will take time.

“We have to distinguish between two things. One is science and the second one is technology scale-up.”

In September 2024, Lihytech, a KAUST startup, announced a partnership with Aramco to strategically collaborate on recovering lithium from oilfield brines using direct lithium extraction technology and a membrane developed at KAUST. 

Ghaffour is also collaborating with a Singaporean company, MediSun Energy, to integrate desalination with energy and mineral production, aiming to optimize these processes as a whole. A pilot facility has already been installed in China, with plans for another installation in Saudi Arabia. 

“The whole world is working on this (mineral recovery and optimizing desalination). We will see a lot of developments in this, in my opinion,” he said.

  • Chad abruptly ended its defense cooperation pact with France
  • Experts say that without Chad, French army will struggle to run other Africa operations

NAIROBI/GENEVA: A French plan to significantly reduce its military presence in West and central Africa risks backfiring and further diminishing the former colonial power’s influence in the region at a time when Russia is gaining ground.
A French envoy to President Emmanuel Macron this week handed in a report with proposals on how France could reduce its military presence in Chad, Gabon and Ivory Coast, where it has deployed troops for decades.
Details of the report have not been made public but two sources said the plan is to cut the number of troops to 600 from around 2,200 now. The sources said Chad would keep the largest contingent with 300 French troops, down from 1,000. However, in a surprise move that caught French officials on the hop, the government of Chad — a key Western ally in the fight against Islamist militants in the region — on Thursday abruptly ended its defense cooperation pact with France. That could lead to French troops leaving the central African country altogether.
“For France it is the start of the end of their security engagement in central and Western Africa,” said Ulf Laessing, director of the Sahel Programme at the Konrad Adenauer Foundation in Mali.
“Chad was the aircraft carrier of the French army, its logistical headquarters. If Chad doesn’t exist, the French army will have a huge problem to keep running its other operations.”
In a further blow to France, Senegalese President Bassirou Diomaye Faye told French state TV on Thursday it was inappropriate for French troops to maintain a presence in his country, where 350 French soldiers are currently based. France has already pulled its soldiers out from Mali, Burkina Faso and Niger, following military coups in those West African countries and spreading anti-French sentiment. Paris is also shifting more attention to Europe with the war in Ukraine and increasing budgetary constraints, diplomats said.
The review envisions the remaining French soldiers in the region focusing on training, intelligence exchange and responding to requests from countries for help, depending on their needs, the sources said. Chad’s move to end the cooperation deal had not been discussed with Paris and shocked the French, according to the two sources and other officials. France, which wants to keep a presence in Chad in part because of its work to help ease one of the world’s worst humanitarian crises unfolding now in neighboring Sudan, responded only 24 hours after Chad made its announcement.
“France takes note and intends to continue the dialogue to implement these orientations,” the foreign ministry said in a statement.
One of the two sources, a French official with knowledge of Chadian affairs, said Chad’s government appeared to have seen the French decision to more than halve its military presence there as a snub. Chad also felt the French would no longer be in a position to guarantee the security of the military regime led by President Mahamat Idriss Deby, this source said.
Macron had backed Deby despite criticism since Deby seized power following the death of his father, who ruled Chad for 30 years until he was killed in 2021 during an incursion by rebels. Deby won an election held this year.
In its statement on Thursday evening, released hours after the French foreign minister had visited the Sudanese border in eastern Chad with his counterpart, Chad’s foreign ministry said N’djamena wanted to fully assert its sovereignty after more than six decades of independence from France. It said the decision should in no way undermine the friendly relations between the two countries. Earlier this year, a small contingent of US special forces left Chad amid a review of US cooperation with the country.
The French drawdown, coupled with a US pullback from Africa, contrasts with the increasing influence of Russia and other countries, including Turkiye and the United Arab Emirates, on the continent. Russian mercenaries are helping prop up the military governments of Niger, Mali and Burkina Faso, and are also fighting alongside them against Islamist militants. However, French officials and other sources played down Russia’s ability to take advantage of the French setback in Chad, at least in the short term. The French source familiar with Chadian affairs noted that Russia and Chad back rival factions in Sudan’s war. Russia also has major military commitments in Syria and the war in Ukraine.
