The drive to greater sustainability — whether in the form of reduced carbon emissions, better water stewardship, or more circular products that stay out of the waste stream — is both an opportunity and a threat for chemical and materials manufacturers. In response to global accords such as the Paris Climate Agreement, some chemicals companies have pledged to reduce or reach net-zero emissions by 2030 or 2050. Stakeholders, including investors, regulators and employees, are pressuring companies all along the value chain to act more sustainably. While the term “sustainability” is often interchangeable with “ESG” (environmental, social and governance), our report found the environmental pillar to be most relevant for chemical industry R&D organizations. The EY-Parthenon team examined sustainability through two primary lenses:
1. The development of products and services that enable customers to be more sustainable – for example:
a. Products that are derived from renewable rather than conventional feedstocks like petroleum
b. Products that enable circularity strategies such as recycling or composting
c. New synthetic routes to natural products whose cultivation is environmentally intensive or has resulted in overharvesting
d. Services that enable more targeted and efficient use of products, such as digital farming
2. The development of processes that enable chemical manufacturers to reduce their own environmental footprint — for example, processes that reduce:
a. Energy usage and carbon emissions
b. Other harmful emissions like volatile organic compounds (VOCs)
c. Net water usage
d. Net raw material usage
More sustainable offerings
Sustainability requirements complicate the economics of product development. Financial implications are still critical but can manifest in different ways. Some applications may command a price premium for a more sustainable product (e.g., compostable packaging used for niche, health-oriented packaged food brands), while other applications require at least cost neutrality, if not cost savings, because end customers are not expected to pay a higher price (e.g., packaging for mass market food brands).
While chemical and materials companies produce many products that support or enable sustainable applications (e.g., adhesives for solar panels, separator membranes for rechargeable batteries), markets now demand that traditional products are more sustainable from a product lifecycle perspective. The degree to which companies embrace a truly sustainable framework for innovation and product development varies by their target industries and often by company size. Smaller companies selling into niche B2B applications may focus only on making products safer — for example, by moving away from toxic additives. Going a step further, companies can help their direct customers to lower their environmental impact, such as through use of coatings that cure faster or at a lower temperature. Larger companies selling to consumer goods customers (B2B2C) will also need to focus on using more sustainable raw materials as well as whether their products end up being recycled or deposited in landfills.
While there are many frameworks for categorizing chemicals and materials, they can be split into three main categories for this discussion about sustainability. Thermoplastics such as polyolefins and PET are mechanically recyclable, and producers are increasingly incorporating post-consumer content into the resins they supply. However, many end products such as flexible film packaging are difficult to mechanically recycle economically, so companies are increasingly investing in various chemical recycling (“advanced recycling”) technologies to break plastics back down to chemical building blocks that can be used to make the same resins from which they were recycled or other products.
Thermoset materials such as polyurethanes and epoxies cannot be recycled the same way as thermoplastics and have historically ended up being downcycled or landfilled. While thermosets are generally geared to semi-durable and durable applications, circularity imperatives have driven several companies to develop ways of keeping these materials in the value chain and out of landfills. “It’s not yet a profitable area, but we’re willing to invest even if we just break even,” noted an R&D leader from a major materials manufacturer.
Lastly, small molecules and performance chemicals such as surfactants, fertilizer and solvents, which cannot be readily recycled like plastics or other materials, also require a more sustainable lifecycle. However, chemical manufacturers need to be flexible as they develop new offerings. Some of their customers may require products that are bio-derived, biodegradable, and/or nontoxic. These categories are not mutually exclusive, but R&D organizations and their commercial counterparts need to plan appropriately and establish decision frameworks to serve customers who hold different views of what “sustainable” means.
Sustainability efforts can also increase the resiliency of companies’ supply chains, which is of critical importance in today’s business environment. The R&D leader of a major industrial coatings business mentioned that their organization had been significantly impacted by supply chain disruptions resulting from extreme weather events. By formulating bio-derived inputs rather than those derived from petroleum, the company has increased supply chain resiliency while reducing its environmental impact.
A typical complication is that a sustainability improvement in one dimension of a product or process may decrease performance in another. For example, chemical recycling technologies can help keep plastics out of landfills, but they also require more energy to run the recycling process, resulting in potentially higher emissions. Commercialization may also result in unintended consequences. To mitigate this risk, the R&D head of a global packaged food manufacturer cited the example of higher value, “flywheel” technologies that enable multiple benefits. For example, food companies would find very high value in a high-intensity sweetener that has the health benefits of lower sugar content, has a lower emissions footprint due to reduced volume to be shipped and is renewably sourced.
Sustainability in the process environment
In addition to the product portfolio, R&D organizations continue to focus on supporting their companies’ operations from a sustainability standpoint. Historically, many efforts to reduce the environmental impact of operations simply fell under the category of general productivity improvement. These include efforts to reduce waste, energy consumption, number of process steps and other factors. Several executives cited the increased importance of these initiatives to their internal and external stakeholders, particularly in water usage, which has not always been a financially impactful aspect of operations.
Chemical producers and their downstream customers are doing more to reduce the environmental impact of their processes. For example, petrochemical producers such as Dow are now planning to sequester carbon emissions from their operations and employ autothermal reforming technology to convert off-gases such as methane to hydrogen used to heat crackers. Additionally, electrification of crackers and other production assets would enable producers to increase the share of renewables in their overall energy consumption.
Sustainability metrics in the innovation management process
To identify and meet sustainability goals, R&D organizations need to implement sustainability metrics in their development processes. Most executive interviewees noted that their innovation management processes, including stage-gate frameworks, are evolving or have already evolved to include sustainability metrics. These metrics are generally being tracked but are not yet being used as decision criteria to continue or cancel projects, though companies are moving in this direction. At a midsize specialties producer, the R&D head noted that they are deprioritizing development efforts lacking a positive sustainability profile and are targeting 70% of new product development to have a positive sustainability impact over the next five years.
