The future of the ethylene industry lies in our ability to adapt, innovate, and commit to sustainability. Let us embrace these challenges and work towards a prosperous, sustainable future.

In a world grappling with environmental challenges, the urgency to transition towards sustainable solutions has never been clearer. Among the most pressing issues is the accumulation of plastic waste, posing threats to ecosystems, human health, and wildlife. However, within this crisis lies a remarkable opportunity: the adoption of circularity principles for all materials, with plastics at the forefront. In this blog, we'll delve into the compelling case for embracing circularity, its transformative potential, and the key steps needed to realize this vision.
Decoupling Growth from Resource Consumption
The linear economy model, reliant on finite resources like fossil fuels, is unsustainable in the long run. Circular economy principles advocate for decoupling economic growth from resource consumption by keeping materials and products in use for as long as possible. This shift not only conserves valuable resources but also reduces waste and pollution, leading to a more resilient and sustainable economy.
Plastics: A Looming Environmental Threat
Plastics, known for their longevity and persistence in the environment, pose significant challenges. They can take hundreds of years to decompose, accumulating in landfills and oceans, endangering marine life, and compromising ecosystems. Embracing circularity for plastics is essential to mitigate these threats by reducing waste, maximizing material value, and minimizing environmental impact throughout the product life cycle.
Unlocking Lower Energy Intensity and Enhanced Design
Circularity promotes lower energy intensity by minimizing the need for energy-intensive steps like extraction and processing of virgin materials. Designing products for durability, reparability, and reuse further enhances energy efficiency and resource conservation. By extending the lifespan of end products and implementing repair and reuse strategies, circularity fosters a more sustainable approach to consumption and production.
The Power of Awareness and Regulation
Increasing public awareness about the importance of recycling and the environmental consequences of plastic pollution is vital. Equally crucial are regulatory and policy requirements that promote recycling and hold producers accountable for managing the end-of-life of their products. These measures create a conducive environment for circularity, driving systemic change and fostering sustainable practices across industries.
Key Steps Towards a Circular Economy
To transition to a circular economy, several key steps and considerations must be addressed:

1. Encouraging Circular Business Models: Businesses must prioritize waste reduction, repair, reuse, and recycling. Embracing sharing and leasing models, product-as-a-service concepts, and closed-loop supply chains fosters circularity and drives sustainable growth.
   
2. Policy and Regulation: Implementing comprehensive policies and regulations that promote circularity is essential. Governments play a crucial role in incentivizing recycling and creating an enabling environment for investment and innovation.
   
3. Innovation and Research: Investing in research and innovation is vital for overcoming technical challenges and unlocking new opportunities for circularity. Advancements in recycling technologies and sustainable product design drive progress towards a circular economy.
   
4. Investment in Infrastructure: Developing and investing in recycling infrastructure is critical for promoting circularity. Robust collection, sorting, processing, and recycling facilities are essential for maximizing material recovery and minimizing waste.
   
5. Collaboration and Education: Collaboration among stakeholders and increased public awareness are indispensable for driving the transition to a circular economy. Educating consumers about recycling and waste management fosters a culture of sustainability and collective action.
   

Technology Options for Plastic Recycling
Several technology options are available for plastic recycling, each with its unique strengths and challenges:

• Mechanical Recycling: Sorting, cleaning, and melting plastic waste to produce pellets or flakes for manufacturing new products.
• Chemical Recycling: Breaking down plastic polymers into chemical constituents for producing new plastics or other products.
• Feedstock Recycling: Converting plastic waste into feedstock or raw materials for fuels, chemicals, or industrial products.
• Biological Recycling: Using microorganisms to break down plastic waste into organic compounds.
• Plastic-to-Fuel Conversion: Converting plastic waste into fuels like diesel or gasoline.
• Upcycling and Downcycling: Converting plastic waste into higher or lower-value products.
• Additive Manufacturing (3D Printing): Utilizing recycled plastics for additive manufacturing processes.

By leveraging these technology options and integrating them into comprehensive waste management strategies, we can accelerate progress towards a circular economy for plastics and materials.
Conclusion
Embracing circularity is not just a choice; it's a necessity for safeguarding our planet and securing a sustainable future for generations to come. By decoupling growth from resource consumption, minimizing waste, and maximizing material value, we can create a more resilient and prosperous economy. The time to act is now. Let's seize the opportunity and embark on the journey towards a circular economy for all materials, with plastics leading the way. Together, we can make a lasting impact and build a brighter, more sustainable future.

The global petrochemical industry has long been a pillar of modern society, providing the essential materials for countless products that drive economies and improve quality of life. Yet, as the world confronts the pressing realities of climate change, this industry faces a pivotal challenge: how to transform its operations to align with ambitious NetZero goals by 2050.
Achieving this vision requires a comprehensive strategy that encompasses the phasing out of inefficient assets, decarbonizing existing infrastructure, and building new, carbon-neutral facilities to meet future demand. Here's a look at the path ahead and the technologies and practices that can drive the petrochemical industry's energy transition.
The Need for a Sustainable Transition A sustainable transition within the petrochemical industry is crucial for reducing greenhouse gas emissions. However, sustainability goes beyond carbon reduction; it requires efficient resource utilization, circularity, water conservation, and responsible land use. Equally important is the consideration of social and economic impacts, ensuring that measures taken to address climate change do not create new vulnerabilities or disproportionately impact certain communities.
The Role of Technology in Decarbonization The journey toward NetZero by 2050 involves the adoption of both near-term and long-term technologies. By focusing on energy efficiency, carbon capture and sequestration, renewable energy, and advanced recycling, the industry can make significant progress in reducing its carbon footprint.
Technologies for Near-Term Deployment Several technologies are ready for immediate implementation, enabling the petrochemical industry to achieve key milestones in the 2030 to 2035 timeframe:

• Low-Emission Designs: Improving energy efficiency, yield, and operational performance in high-temperature processes such as steam cracking and synthesis gas production.
• Blue Hydrogen: Using hydrogen produced with pre-combustion carbon capture and sequestration as a fuel source.
• Post-Combustion Carbon Capture: Capturing carbon emissions after combustion and storing or utilizing them.
• Carbon-Free Electricity: Transitioning to renewable energy sources for electricity consumption.
• Renewable Feeds: Utilizing renewable feedstocks where available.
• Advanced Recycling: Transforming waste plastics into raw materials, reducing reliance on fossil fuels.

Medium-Term Innovations Looking ahead, new technologies will help drive further carbon reduction based on reliable availability of carbon free electric power:

• Electric Reactors: Electrically heated and shockwave reactors offer energy-efficient alternatives for high-temperature processes like steam cracking.
• High-Capacity Electric Drives: Reliable electrical drives capable of handling 100 MW or more can reduce emissions by eliminating the need for combustion-based power sources.

Longer-Term Vision Beyond 2035, the petrochemical industry must continue to innovate. Potential game-changers include and many other innovations in the early stages of screening:

• Utilizing Captured CO2: Transforming captured carbon dioxide into valuable products like olefins, contributing to circularity.
• Chemical Looping Reactors: Eliminating greenhouse gas emissions through innovative reactor designs.

The Role of Policy and Investment Achieving NetZero by 2050 requires a supportive policy framework. Governments can drive change through incentives, regulations, and funding for innovation and infrastructure. Additionally, investments in transition technologies enable growth and are fueled by increasing demand for sustainable products and practices.
Embracing the Energy Transition The energy transition in the petrochemical industry is not merely a matter of compliance; it is an opportunity to lead the way in sustainable practices, foster innovation, and contribute to a cleaner planet. By embracing new technologies, focusing on resource efficiency, and adopting a holistic approach to sustainability, the industry can transform itself and play a pivotal role in achieving global NetZero goals.

As we approach the end of this year, I would like to share a summary of my thoughts on the outlook for the ethylene (light olefins) industry.
Energy Shifts

• Renewable power share is increasing, albeit at a somewhat slower pace than needed to meet transition targets.
• Coal is still a significant source of power generation driven by multiple factors – including energy security, affordability, competitiveness, self-reliance, etc.
• Oil demand is now expected to peak in the next 5-8 years, later than previously anticipated in transition scenarios.
• The cost of batteries for power storage is declining significantly, thus helping renewable power.

The slower shift will likely have an impact on electrification efforts in the petrochemicals sector.
Feedstock Trends

• Oil-producing countries in the Middle East and major petrochemical demand/growth regions are investing heavily in Crude-to-Chemicals production approaches.
• Ethane exports from the US are expected to increase over the next 5 years.
• Industry continues to look for renewable feed sources – penetration is expected to be limited to some regions and will be slow, and challenges remain about competition with other applications, landmass utilization, infrastructure, etc.
• Ethane feedstock is expected to remain advantageous feedstock in North America and the Middle East. Crude Oil prices are expected to stay at elevated levels in the foreseeable future.

Light olefins are experiencing low utilization rates, and the margins will remain under pressure during 2024. The oversupply situation is dampening investments in North America, while Asia and the Middle East are continuing to add capacity.
Sustainable Pathways
The petrochemical industry has started to invest in its journey toward NetZero targets at a somewhat slower pace, however, uncertainty and risks remain. The industry is making progress in some of the pathways towards sustainability as below:

1. Some of the technologies that are currently under development and/or in the demonstration stage include:
   1. Electrical cracking furnace
   2. Shock wave reactor concepts (e.g. RotoDynamic Reactor) driven by electrical power
   3. Converting carbon dioxide to ethylene
2. Carbon capture applications include:
   1. Some of the crackers are moving forward with pre-combustion carbon capture applications using the auto-thermal reforming concept to produce blue hydrogen as a source of heat for cracking furnaces.
   2. Many companies are evaluating post-combustion carbon capture technologies.
3. Some companies are evaluating green hydrogen as a source of heat; however, current economics pose a challenge. Many companies are looking at external blue hydrogen supply.
4. Some companies are evaluating options for using Small Modular Reactor concepts using nuclear energy for generating power and steam.
5. Circularity:
   1. Many companies have made commitments for advanced recycling facilities (multiple technologies) to replace fresh hydrocarbon feeds. However, challenges remain due to lower carbon efficiency and high energy intensity as well as contaminants in the recycled feed.
   2. Companies are working on concepts to develop circular approaches that can help keep materials in use and at their highest possible value throughout their life.

Keeping the energy transition efforts focused, efficient, and effective requires a great deal of abstract and impartial thinking based on breadth and depth of experience, industry insights, and knowledge. Apex PetroConsultants can help by bringing the value of strategic thinking, specific industry insights, knowledge, and a depth of experience.

Cracking furnaces’ reliability, in simplistic yet effective terms, can be measured by looking at the actual production relative to their overall capability. Many factors, from design/engineering/fabrication/construction through operation and maintenance, contribute towards overall availability and reliability. The furnaces typically determine the total ethylene plant capacity limits and require significant attention, throughout their lifecycle, to achieve best-in-class performance and availability expectations.
Key factors during project development and execution:

• Selection and design of main components – radiant coils, convection coils, transfer-line exchangers, burners, fans, SCR, etc.
• Process controls, monitoring, and safety systems
• Engineering specifications
• Fabrication details, inspection
• Quality of construction

Operation and Maintenance (a lot depends on operation and maintenance strategies along with discipline):

• Working knowledge of fundamentals on the process side (feeds, yields/severity, selectivity, coking/fouling/run-length, decoking, corrosion, erosion, etc.) and fireside (combustion, burners, SCR, emissions, fouling/corrosion/erosion, etc.)
• Design limits, process safety
• Operating variables/interactions, controls, performance monitoring
• Operating modes and procedures
• Predictive and preventive maintenance, frequency (relationship of operating parameters, failure modes, etc.)
• Equipment monitoring
• Personnel training and competency

Many of these factors are interconnected and require a deep understanding to develop a holistic approach for maintaining high reliability and availability to achieve maximum utilization of cracking furnaces.

IMF forecasts GDP growth of 2.8% which is slower than in 2022. Some of the observations of current market conditions are summarized below:

• The last year ended with a significant reduction in the capacity utilization of crackers globally. The largest impact was in Asia and Europe, and the somewhat lower impact was on ethane crackers in the US. Things are expected to improve in H2 2023, and the US will see higher overall utilization. Economic uncertainty remains.
• Ethylene exports have helped to balance supply and demand and are expected to grow in 2023.
• Ethane feed has remained an advantaged feedstock even with higher prices as compared to the pre-pandemic levels. This has impacted the cracker margins. Asia was mostly in negative margin territory for naphtha-based plants. Asia has added significant capacity in late 2022 and early 2023, further affecting supply-demand imbalances. The US started up three new crackers in late 2021 and 2022.
• Average cost of production for US ethane crackers jumped by almost 80% in 2022 while ethylene prices fell. While the cost of production will ease some, margins will remain tight due to the over-supplied situation globally.

The strategic focus for the industry in 2023 and beyond that can differentiate winners from losers will be:

1. Improving competitiveness through capacity utilization and performance improvements.
2. Meeting energy transition goals through carbon footprint reduction.
3. Working towards circularity goals.
4. Accelerating innovation and technology developments

At Apex PetroConsultants, we advise owners and operators in each of these areas and work together with their teams to turn these ambitious goals and objectives into reality.

Energy transition to achieve NetZero goals will be a tremendous achievement, as the transitions are never easy and take a long time and commitment. The industry will need to make progress in the transition journey by keeping the roadmap to NetZero in mind to avoid a disorderly transition while focusing on no-regret decisions.
We have seen many positive signs of progress and announcements in many areas and industries. On a broader basis, the commitments made in Paris Agreement or later, both the private sector and governments are falling behind on the transition path. Current forecasts indicate that at the current pace, the warming levels could be closer to 2.5 degrees Celsius vs. a reference case of 1.5 degrees set by IPCC.
Some of the factors (listed below) have offered opportunities for acceleration, and acted as headwinds at the same time:

• Energy crisis driven by conflicts.
• Economic downturn and higher inflation.
• Frequent extreme weather events causing food shortages, and social and political pressures. These events also result in a significant financial impact.
• Geopolitical conflicts and an increasingly fractured world.
• Trade conflicts, and supply chain disruptions.

Hydrocarbon Processing Industry (HPI) has a significant role to play in the transition as it has the resources (including skilled personnel, technology, innovation, and finances) to accelerate the process. We will still need carbon sources to produce plastic materials that are not only essential for the quality of life we enjoy but also needed to help lower carbon emissions by exploiting renewable resources and by improving energy efficiency. The demand for these products will grow with population growth, expanded middle-income earners, and urbanization but also new applications that help in accelerating the transition. The industry needs to follow a long-term sustainable model that encompasses these among other requirements:

• Focus fossil fuels away from direct contributions towards greenhouse gas emissions as much as practicable.
• Minimize the hydrocarbon feed demand through design approaches to extend product life, making them repair-friendly, and easily recyclable at high economic value.
• Minimize losses to improve overall efficiencies throughout the life cycle.
• Invest in technologies that will speed up the transition towards NetZero goals.

Energy transition has offered the HPI industry a sustainable path for growth in the future. The key is to take a longer-term business view rather than a short-term focused strategy.

During the 2022 Ethylene Producers Conference, I moderated the Panel Session on the subject of “Energy Transition & Decarbonization”. In this blog, I have highlighted key points from the panel session (The panel included Derik Broekhoeff of Stockholm Environment Institute, Rachel Meidl and Jim Krane of Rice University’s Baker Institute for Public Policy).

• Public opinion in most countries, with a few exceptions, is hardening around the need to do more to address the changing climate.
• Companies are incorporating sustainability into their business strategies fueled by pressure from shareholders, stakeholders, and regulations.
• Rising global population, middle class result in higher demand for energy, materials and minerals placing pressure on land use.
• Humanity will need more energy in the future. But the overall energy business could shrink – in volume and in revenue. Part of it depends on how much of the fossil fuel system gets replaced by technologies that don’t use fossil fuels. A shift to renewables would use less material and less trade.
• The products derived from petrochemicals, including plastics, are likely to be indispensable for a range of low-carbon, energy efficient applications in transportation, buildings, agriculture, medical, and consumer goods. The challenge is therefore how to decarbonize the petrochemical production while still meeting the surging demand.
• Global nature of the industry makes the transition efforts economically challenging.
• Decarbonization is more than simply using cleaner fuels and improving efficiency.
• Changing production processes and systems, developing new infrastructure, developing and deploying new technologies to avoid or capture emissions in ways that are economically sustainable.
• The feasibility of different pathways would depend heavily on the development of, among other things, large-scale renewable energy deployment, green/blue hydrogen technology and infrastructure, carbon capture and storage technologies, electrification of production processes (both new and existing technologies).
• Pathways to decarbonization need to comprehensively address all elements of the chemical industry value chain – including upstream production (extraction, separation, refining etc.), downstream derivatives and end use sectors etc. Significant amounts of carbon are embedded in the final products which may be emitted over time depending on end-of-life disposition. Therefore, plastic recycling will be an essential part of decarbonization.
• Over the next 30 years, worldwide solid waste generation is estimated to increase to nearly 3.4 billion tonnes per year.
• Plastics recycling is challenging because the majority of the plastics cannot be recycled in current systems because of complexity, multi-material, customized, contaminated and have additives. The small percentage that is suitable for recycling within current systems can only be recycled a limited number of times due to degradation and therefore downgraded to lower value products.
• In a circular economy, we want to keep the molecule in play as long as possible and material at an economic value. As a part of the transition, plastics production will need to move from linear model to circularity. This potentially would include measures to manage demand, product design requirements and extensive recycling (mechanical as well as advanced).
• As a society, we have failed to see the challenge holistically, in ways that address diverse forms of materials throughout our system becoming waste. Without looking at this broadly, we will continue to compound the increasing waste issue and have a short-sighted version of system level sustainability.
• Sustainability includes multiple factors and their interactions in a wide array related to environment, social and economic aspects. Focusing solely on the separate parts creates vulnerabilities by shifting risks elsewhere in the system, thus producing unsustainable and undesirable outcomes. Circular systems are regenerative by design.
• A circular economy increases resource-efficiency, keeps materials in use and at their highest value throughout its life, decouples growth from the consumption of finite resources through responsible sourcing, reuse/repair/reman, recycling, and other strategies.
• Geopolitics can potentially result in a strong rationale for moving away from fossil fuel-based systems due to energy security needs. Depending on policy choices, the global energy trade may shrink over time. All these changes suggest that the strategic importance of oil and oil producers will decline. Companies decarbonizing their supply chains. Decarbonization pressure is moving down the chain to small suppliers in countries where there is no government pressure.
• For effective policy, the traditional approaches (carbon pricing, technology subsidies, regulations) may not be enough and would need to be extended through research and development/demonstration funding; support for deploying new technologies and infrastructure; measures to foster new markets for low-carbon materials.
• Resources that U.S. industry can bring to bear including financial resources, technical knowledge, research capacity, and workforce skills that can make it potentially a global leader for industrial decarbonization.

To meet the emission budgets in this century (as estimated by IPCC ~800 billion-ton CO2 for <2 oC target). If we stay with current growth and demand targets, these emissions are insufficient for materials production alone. Materials sector allocation to achieve the 2 oC scenario is 300 Gt CO2. As so much of carbon is either built into the products (plastics) that is released at end of life or required by energy intensive production (steel, cement, petrochemicals), circularity is a must to achieve these targets. We need to focus on the essential elements for a successful outcome and to avoid disorderly transition.

Ethylene industry has made limited progress in decarbonization at a global level, partly driven by demand growth exceeding the energy efficiency gains. Industry can still gain energy efficiency by applying the best available technologies, but aging assets provide limited economic potential to achieve the targets leading up to net-zero emissions.
Challenges

• Majority of the energy consumption in ethylene plants is for high temperature cracking furnaces, which complicate the deployment of renewable electricity.
• Majority of the ethylene production growth is integrated with refinery operations resulting in petrochemicals yields higher than 50% of crude oil input. The integration of refinery and petrochemicals complicates the energy accounting for the petrochemical products as the energy is locked in.
• Nearly a two-third of the emission reduction potential relates to the energy used in production processes of the materials (e.g. plastics), the remainder with the materials systems (flows and supply chain) optimization.
• Most of the ethylene is currently produced from hydrocarbon feeds. Plastic production based on biomass is currently less than 1% of the current consumption. The high cost of low-carbon alternatives is a major barrier for entry.
• After decades of effort, plastic recycling is not well developed, and industry has been trying to improve this situation. Majority of the post-consumer plastics and textiles are either dumped in landfills or incinerated to recover some of the energy value. Low recycling rates and low energy recovery rates add to the carbon emissions. Chemical recycling utilizing pyrolysis technology results in significant carbon and energy losses.
• Industry would need a significant amount of investment in clean energy supply in combination with new facilities (to replace some of the aging and inefficient assets) to meet the demand growth and emission reduction technologies. This would lead to a high mitigation cost, given the current levels of energy and feedstock supply cost.
• Some of the studies project high levels of contribution from biomass feedstock. The risks and uncertainty about availability of these (in competition with food needs and land use) will play a major role in the viability of biomass feedstock.

Options & Pathways (Net-zero will require combination of options)The challenge will be for the existing assets and assets under design and construction to find an optimum net-zero path.

• Energy Efficiency
• CCUS (Carbon Capture Utilization & Storage)
• Fuel Switching, in combination with emission reduction technologies
• Clean Power, process electrification
• Alternative Feedstocks
• Circularity & Materials Systems Optimization (Flows and Supply Chain)

Affordability and reliability will be key for net-zero growth. Infrastructure will be vital, for meeting net-zero targets, including

• Renewable power grids
• Pipelines for CO2, hydrogen and other fuels (heat)
• Waste handling logistics and recycling

I have discussed this issue and along with some ideas in previous blogs. Net-zero approaches and interim targets will be impacted heavily by the policies and framework at national and local levels. 

A recent announcement by Dow to build the world’s first net-zero carbon emissions ethylene and derivative complex(https://investors.dow.com/en/news/news-details/2021/Dow-announces-plan-to-build-worlds-first-net-zero-carbon-emissions-ethylene-and-derivatives-complex/default.aspx) is a showcase example for the petrochemical industry.

The proposed complex will achieve this utilizing the current best available technologies. The high-temperature cracking furnaces will use hydrogen as a fuel for providing the necessary heat input for the process. This will eliminate the carbon dioxide emissions from the furnaces. Hydrogen will be generated using an auto-thermal reforming (ATR) process with a carbon capture step. The captured carbon dioxide will be transported and stored in adjacent infrastructure. (https://cen.acs.org/environment/greenhouse-gases/Dow-details-plan-decarbonize-petrochemical/99/i37). The advantage of this approach is that owners can decarbonize existing assets with minimum changes, provided they have access to infrastructure for carbon storage and utilization.

There are potentially many factors that may have contributed to the decision-making process. Canada’s  Pan-Canadian Framework on Clean Growth and Climate Change played a role that creating market-based carbon pricing mechanisms and financial incentives to reduce greenhouse gas emissions and make the reductions economical. Alberta province has two market-based policies including a carbon tax and an output-based pricing system for emissions reduction. This provides certainty to businesses in their decision-making process.

The companies will have to assess individual facilities and sites to develop the most appropriate approaches as they can vary significantly from one site to the other.

At Apex PetroConsultants, we advise client teams to evaluate decarbonization approaches for each individual facility and site that are economical to meet short to mid-term targets while focusing on the longer-term net-zero approaches for new and existing assets.
