Region prepares for circular plastics economy

23 June 2023

 

Representatives from the Gulf petrochemicals industry, plastics manufacturers and wider derivatives producers gathered at the Gulf Petrochemicals & Chemicals Association plastics conference in Saudi Arabia in May. There, it was agreed that while a “demonisation” of the plastics industry had indeed taken place, this was not entirely unjustified.

The Gulf region is a major producer of plastic products, among other petrochemicals derivatives. Furthermore, the GCC has been investing significantly in building large production complexes for petrochemicals – the basic feedstock for the manufacturing of plastics. 

However, despite irresponsible plastics usage and wastage being major environmental pollution issues worldwide, only about 10 per cent of plastics are recycled at present. This is due to the variability of plastics waste, contamination and gaps in the existing infrastructure.

“Every person on this planet is probably horrified by the pictures of plastic objects floating in the ocean, wildlife entangled in or ingesting plastic and mountains of plastic on dump sites and littered everywhere,” says Martyn Tickner, chief adviser of circular solutions for Alliance to End Plastic Waste, an industry-funded non-profit organisation based in Singapore. 

“Such pollution is a problem of lack of basic waste management. Three billion people – more than 35 per cent of the global population – are considered to lack access to adequate solid waste collection and properly managed disposal.”

Major pollution source

About half of global plastic waste is sent to landfill, about 20 per cent is incinerated, and the rest is either littered or burned in the open, causing severe pollution both on land and in the seas.

“Plastic, due to its non-biodegradable nature and potential toxicity, demands responsible usage and disposal,” says Hani Tohme, managing director – Middle East and head of sustainability in the Middle East and North Africa (Mena) region at Roland Berger, an international management consultancy headquartered in Germany. 

“However, current consumption patterns – particularly the reliance on single-use plastics – coupled with often insufficient waste management infrastructure, lead to widespread environmental pollution. 

“When not properly managed, plastic contributes significantly to land litter, marine pollution, and overall environmental degradation,” he says.

The need for recycling

Many of the severe environmental pollution problems arising from unsustainable plastics utilisation and the consumption of single-use plastics can be mitigated through the adoption of a circular plastics economy.

This is a system aimed at “reducing plastic waste globally”, say Devesh Katiyar, principal, and Jayanth Mantri, manager, at Strategy& Middle East, part of the PwC network. 

“It involves products designed for recyclability, efficient collection and sorting of plastic waste, advanced recycling technologies and policies to promote recycling.” 

They add that the scope of a circular plastics economy is global. “Annually, about 400,000 tonnes of plastic waste is traded globally, despite several restrictions. Driving circularity in plastics helps to reduce waste, conserve resources and avoid emissions and energy use associated with virgin plastics production, thereby promoting a sustainable and eco-friendly approach to managing plastics.”

Roland Berger’s Tohme adds that a circular plastics economy “disrupts the traditional linear model of ‘take-make-waste’ by adopting a restorative and regenerative approach”. 

“This framework incorporates the principles of ‘reduce, reuse and recycle’, along with strategies for designing out waste and pollution, maintaining products and materials in circulation and regenerating natural systems.”

Developing a circular and low-carbon economy for plastics requires changes at every stage of the plastics value chain, both upstream and downstream, says Tickner.

“Upstream solutions are those that endeavour to reduce the magnitude of the problem through the elimination of unnecessary use, the adoption of more sustainable alternatives and the redesigning of supply chains and delivery models to encourage reuse.” 

These solutions disrupt the root causes of today’s environmental crisis, he adds. “Reuse within the commercial, business-to-business supply chains – for example of packaging used to deliver from factory to warehouse – can be adopted quite quickly.”

Downstream solutions, meanwhile, are post-use. “Here, 100 per cent collection is a basic requirement to eliminate leakage into the environment,” Tickner explains.

The successful implementation of a circular plastics economy requires systemic changes and collaboration among stakeholders, including governments, businesses and consumers

Open or closed loop

The plastics recycling process can be categorised as open-loop or closed-loop. 

Open-loop recycling is typically mechanical – converting plastic waste into less demanding plastic applications or using it in other material economies, such as the construction industry.

Closed-loop recycling means returning plastic back into high-value plastic applications, either directly, through advanced mechanical or dissolution technologies, or back to chemicals feedstock via chemical recycling. 

The technologies required to recycle almost all types of materials are available, or are rapidly emerging. As a result, overcoming the recycling challenge is primarily an issue of creating the right financial environment to enable major investment in the collection, sorting and recycling infrastructure.

The commercial case for plastics recycling 

Role of governments

Regional governments and regulatory authorities will need to play a role in supporting the growth of the plastics industry, as well as in ensuring the effective and sustainable consumption of plastics.

“A circular plastics economy offers a transformative approach to addressing the plastic waste crisis, promoting economic growth while reducing environmental impact,” says Tohme. “However, the successful implementation of this model requires systemic changes and collaboration among stakeholders, including governments, businesses and consumers.” 

Robust frameworks and proven best practices “play a pivotal role in guiding organisations to develop sustainable strategies, innovative business models and effective operational transformations, ultimately determining the success of their transition to a circular economy”, he says.

Strategy& Middle East’s Katiyar and Mantri note that governments and regulatory authorities can support the sustainable growth of the plastics industry in several ways. 

“They can implement policies and regulations such as bans and taxes on single-use plastics, extended producer responsibility programmes and incentives for advanced recycling and imports of plastic waste destined for recycling.

“In addition, they can create global closed-loop supply chains and material marketplaces to gain access to feedstock. And they can develop infrastructure for the collection, sorting and recycling of plastic waste – both within the region and abroad,” they continue. 

“The Mena region has the potential to attract investments of between $30bn and $40bn over the next two decades,
to build a truly world-class recycling infrastructure.”

The problems with plastics
  • Non-biodegradable: The environmental concerns surrounding plastic stem largely from its non-biodegradable nature. Most plastics take hundreds of years to decompose naturally. This inherent property means that plastic waste tends to accumulate in the environment over time rather than breaking down and returning to the ecosystem.
  • Microplastics and toxic chemicals: When plastics degrade, they break into tiny particles known as microplastics rather than biodegrading. These particles can be ingested by wildlife, with detrimental and often fatal results. Moreover, certain types of plastics contain chemicals that can leach out over time, particularly when exposed to heat or sunlight. These chemicals can contaminate soil and water, posing risks to wildlife and potentially infiltrating the food chain.
  • Greenhouse gas emissions: The impact of emissions is related on the one hand to the production of plastics – making virgin plastics, for instance, from oil – and on the other hand to the open burning and incineration of plastics after they have been disposed of in systems that lack proper waste management. This is happening in both developing and developed countries.
Addressing the environmental impact of plastics
  • Reusability: Most plastics consumed today are single-use plastics, in packaging and fast-moving consumer goods (FMCG) products such as plastic bags, straws and cutlery. A shift from single-use to reusable plastics is an important way to reduce the volume of plastic being consumed, thus reducing the overall impact. 
  • Light-weighting: Another key way to reduce the volume of plastic consumed is to reduce the weight of the plastics in products. This has been an area in focus for FMCG and packaging companies in recent years.
  • Design: Plastic packaging and products that are made of plastic layers glued with other fibres and laminates cannot be recycled easily, or at a cost that does not exceed the actual value of the material. Therefore, designing plastics products and packaging that are recyclable is another way to address the environmental impact of plastics.
  • Inadequate waste management and resulting pollution: Compounding these issues, an inadequate waste management infrastructure in many parts of the world is unable to effectively handle the volume of plastic waste. This leads to widespread littering of landscapes and waterways, accumulation of plastic in landfills and marine pollution. About 8-12 million metric tonnes (mt) of plastic enters our oceans each year, significantly threatening marine life – some estimates are even as high 14 million mt. On land, plastic waste similarly disrupts habitats and negatively impacts wildlife.

  • Rainmaking in the world economy

    19 April 2024

    Commentary
    Edmund O'Sullivan
    Former editor of MEED

    The biennial IMF World Economic Outlook released on 16 April forecasts that global growth will hold steady at just over 3% in 2024.

    That is despite Russia’s war on Ukraine and the risk that Israel’s war on Gaza will trigger a regional conflict and jeopardise oil exports from the region.

    This is an unexpected prospect – rather like a meteorologist forecasting that the UAE will get the equivalent of a year’s rainfall in a single day, as it did in mid-April.

    A soft landing for the world economy despite the risks is by that standard less surprising. But these things don’t just happen.

    Just as the UAE’s greatest flooding incident since records began was exacerbated by creeping climate change, according to experts, global growth is believed to be robust because of determined action to keep prices down, cut inflation and boost the supply of goods and labour.

    The challenge to the rosy outlook, however, is not hard to find. Several key stress factors are in the US.

    The biggest threat to the IMF’s forecast is from events in the Middle East

    American fiscal policy under President Joe Biden has been extremely loose. The US budget deficit to 2030 is forecast to average 6% of GDP. Its debt-to-GDP ratio – now above 100% – will rise for the foreseeable future.

    Even the IMF, always reluctant to criticise its biggest shareholder, says this looks unsustainable. 

    More than 3 million migrants arrived in the US last year and the proportion of foreign-born residents in America is approaching an historic high. A more contentious issue is that more than 2 million undocumented migrants also entered the US in 2023 and the figure is rising.

    Donald Trump is making migration an issue in his campaign to regain the White House. This is fuelling concern among US voters that could precipitate restrictions on immigration.

    The biggest threat to the IMF’s forecast is from events in the Middle East. On the night of 13 April, Iran launched drones and missiles on Israel in retaliation for its attack on Tehran’s Damascus consulate two weeks earlier.

    Oil prices spiked ahead of Iran’s attack and eased back on expectations that there would be no wider regional conflagration. But higher levels of risk are being built in to forecasts of oil prices, which are around a quarter higher than they were in January. Even without an escalation, oil is heading towards $100 a barrel this summer.

    This doesn’t have to happen, however. With concerted international diplomatic efforts on stage and behind the scenes, the world has the capacity to block the path to a new Middle East war and all it entails. 

    But does it have the will?

  • Masdar and Etihad plan pumped hydro project

    19 April 2024

    Abu Dhabi Future Energy Company (Masdar) and Etihad Water & Electricity (Ethad WE) have signed a memorandum of understanding (MoU) to develop several clean energy projects in the UAE's northern emirates.

    The planned projects include a solar photovoltaic (PV) project, a pumped hydro storage project and a potential battery energy storage system facility.

    The two companies signed the MoU on 18 April, the final day of the World Future Energy Summit in Abu Dhabi.

    "This agreement aims to formalise the intention of the parties to further discuss the potential areas of collaboration and possible projects," Masdar said in a social media post.

    Etihad WE is responsible for the procurement and offtake of water and power production services in Umm Al Quwain, Ras Al Khaimah, Ajman and parts of Sharjah.

    Masdar and Emirates Global Aluminium (EGA) announced an agreement to work together on aluminium decarbonisation and low-carbon aluminium growth opportunities during the same event.

    As part of the agreement, Masdar and EGA will also work together internationally to find opportunities through which Masdar will support EGA to power new aluminium production facilities with renewable energy sources.

  • Ewec signs Ajban solar PV contract

    19 April 2024

    Abu Dhabi state utility Emirates Water & Electricity Company (Ewec) has signed an agreement for the development and operation of Abu Dhabi’s third utility-scale solar photovoltaic (PV) independent power project (IPP).

    A team led by French utility developer EDF Renewables and including South Korea's Korea Western Power Company (Kowepo) won the 1,500MW Al Ajban solar PV IPP contract.

    Ewec announced the official signing of the contract on 18 April, the final day of the World Future Energy Summit in Abu Dhabi.

    As with previous solar PV projects in the emirate, Abu Dhabi Future Energy Company (Masdar) will own a stake in the special purpose vehicle that will implement the project.

    It is the second major contract won by the French-South Korean team in the GCC since March last year. The team previously won the contract to develop and operate the 500MW Manah 1 solar IPP in Oman.

    EDF, along with Masdar and Saudi contracting company Nesma, also won the contract to develop and operate the 1,100MW Hinakiyah solar IPP project in Saudi Arabia in November.

    The EDF-led team submitted the lowest levelised electricity cost of 5.1921 fils a kilowatt-hour (kWh) or about 1.413 $cents/kWh for the Al Ajban solar PV IPP contract, as MEED reported in July 2023.

    Japan’s Marubeni submitted the second-lowest bid of 5.3577 fils/kWh.

    Ewec requested proposals for the contract in January 2023 and received bids in late June 2023. It qualified 19 companies to bid for the contract in September 2022.

    Delivering goals

    The Al Ajban project – similar to the 1,584MW Al Dhafra solar IPP, which was inaugurated in November, and the operational 935MW Noor Abu Dhabi plant – supports the UAE Energy Strategy 2050 and the UAE Net-Zero by 2050 strategic initiative.

    Ewec aims to install up to 17GW of solar PV capacity by 2035.

    The plan will require the procurement of about 1.5GW of capacity annually over the next 10 years. Over the intervening period, ending in 2030, Ewec plans to have an additional 5GW of solar capacity, reaching a total solar installed capacity of 7.3GW by 2030.

    Ewec expects its first battery energy storage system to come online in the late 2020s to boost balancing the grid's load as more renewable energy enters the system.

    The UAE published its updated national energy strategy in July last year. It includes a plan to triple the nationwide renewable energy capacity to 19GW by 2030.

  • Egypt resumes power cuts

    18 April 2024

    Power cuts resumed across Egypt on 15 April, with scheduled power outages lasting a maximum of one hour per grid zone between 11am and 5pm daily.

    The scheduled power outages began last year and were suspended during Ramadan.

    The electricity ministry has confirmed that, since no new amendments to the load reduction plan have been issued, the power cut plan will continue indefinitely, adding that the outages are expected to last "until at least the end of summer, due to increased grid demand during the hotter months".

    The government-initiated load-shedding programme initially aimed to rein in rising electricity consumption and reduce pressure on the country's gas network.

    According to the country’s Electricity & Renewable Energy Ministry, national electricity consumption reached 43,650MW in mid-July last year, up significantly from previous highs of about 31,000MW.

    While the record-high consumption level is still below the official generation installed capacity of close to 60,000MW, consumption levels of 34,000MW–36,000MW will require about 129-146 million cubic metres of gas and diesel a day.

    Barring load-shedding, any increase in consumption beyond 36,000MW will require a commensurate increase in gas and diesel, which is understood to be beyond the government’s capacity to procure.

    Crucially, the other side of the electricity rationing initiative has to do with the need to save gas for exports, to boost the government’s dollar reserves in the face of the ongoing currency crisis.

  • Ewec wants carbon-capture readiness for next gas power plant

    17 April 2024

    The request for proposals (RFPs) that will be issued for the next combined-cycle gas turbine (CCGT) plant in Abu Dhabi will explicitly require the developers or developer consortiums to accommodate the installation of carbon-capture facilities once they are commercially viable.

    "A key part of the RFP is to make a declaration that this project will be carbon-capture ready … that such facility will be installed as part of the project once carbon-capture solutions become commercially viable," Andy Biffen, executive director of asset development at Emirates Water & Electricity Company (Ewec), told the ongoing World Future Energy Summit in Abu Dhabi.

    As MEED previously reported, Ewec is considering issuing a tender in the next few weeks for its first gas-fired independent power producer (IPP) project since 2020.

    The greenfield Taweelah C gas-fired IPP is planned to reach commercial operation by 2027, according to a recent Ewec capacity procurement statement.

    "We understand that they might skip the expressions of interest and request for qualifications stage and directly invite qualified developers to bid for the contract," two sources familiar with the project previously told MEED.

    The planned Taweelah C gas-fired IPP is expected to have a power generation capacity of 2,457MW.

    Ewec awarded its last CCGT IPP nearly four years ago. Japan's Marubeni Corporation won the contract to develop the Fujairah F3 IPP in 2020.

    The state utility is considering new gas-fired capacity in light of expiring capacity from several independent water and power producer (IWPP) facilities.

    The plants that will reach the end of their existing contracts during the 2023-29 planning period include:

    •  Shuweihat S1 (1,615MW, 101 million imperial gallons a day (MIGD)): expires in June 2025
    •  Sas Al Nakhl (1,670MW, 95MIGD): expires in July 2027
    •  Taweelah B (2,220MW, 160MIGD): expires in October 2028
    •  Taweelah A1 (1,671MW, 85MIGD): expires in July 2029

    Ewec and the developers and operators of these plants are expected to enter into discussions before the expiry of the contracts to decide whether a contract extension is possible. Unsuccessful negotiations will lead to the dismantling of the assets at the end of the contract period.

    In 2022, MEED reported that Abu Dhabi had wound down the operation of Taweelah A2, the region's first IWPP. The power and water purchase agreement supporting the project expired in September 2021 and was not extended.
