Growing energy market volatility is strengthening the case for sustainable materials and fossil-free chemicals, as companies reassess supply chain risks linked to fossil fuel dependence. Industries such as plastics, chemicals, and fertilisers rely heavily on fossil fuel-derived inputs, prompting businesses to explore alternative materials and sourcing strategies as energy availability and pricing fluctuate.
Investors and industry observers say supply disruptions along key trade routes have highlighted vulnerabilities in traditional petrochemical supply chains. Danijel Višević, general partner at climate-focused venture capital firm World Fund, said recent developments have made the business case for alternatives more compelling, particularly as procurement teams factor in volatility and supply risk when comparing fossil-based inputs with domestically produced or non-fossil substitutes.
A significant share of global energy and chemical flows move through major shipping corridors, including roughly 20% of the world’s oil and natural gas, 13% of chemicals such as fertilisers, and a large portion of seaborne sulphur used in batteries. Helium shipments used in semiconductor manufacturing also depend on these routes, underscoring the broad supply chain exposure across industries ranging from packaging and agriculture to electronics and artificial intelligence infrastructure.
Historically, industrial buyers often selected lower-cost fossil-based materials, avoiding what has been described as a “green premium” for sustainable alternatives. However, analysts note that cost comparisons are shifting as volatility affects raw material pricing. Brent crude, a global oil benchmark, recently experienced sharp price movements, prompting concerns that costs for everyday products such as packaging, consumer goods, and industrial materials could rise.
Some startups developing alternatives to fossil-based plastics and chemicals say higher input costs for traditional materials are narrowing the price gap. Companies producing compostable packaging, bio-based chemicals, and fossil-free fertilisers report increased interest from manufacturers seeking both decarbonisation and supply chain resilience. Industry participants say these developments are helping create a more level playing field for sustainable materials.
Beyond plastics, fertiliser supply chains and everyday chemical inputs have also faced price and availability pressures. Battery manufacturing materials and other industrial inputs that move through major shipping routes have similarly drawn attention to supply chain concentration risks. Investors say this environment is driving stronger engagement between startups and large industrial customers exploring long-term sourcing agreements.
Regeneration.VC partner Jamie Rowles said portfolio companies developing alternative materials have seen increased interest from strategic partners and longer-term planning discussions. Such arrangements, he noted, can help improve economies of scale and reduce costs for new materials over time while strengthening supply chain resilience.
Examples cited by investors include startups working on recycling and alternative production methods. Biotech company Epoch Biodesign uses engineered enzymes to break down nylon-6,6 into its original chemical components, offering a potential solution for plastic waste and reduced reliance on petrochemicals. Another company, Nitricity, produces nitrogen fertiliser using air, water, agricultural waste, and renewable electricity, avoiding natural gas inputs and aiming to reduce exposure to energy price swings.
Despite growing interest, analysts caution that demand for fossil-free materials could fluctuate if energy markets stabilise. Previous periods of volatility saw companies sign preliminary agreements with clean chemistry and green hydrogen providers before reverting to conventional inputs once prices eased. Investors say long-term offtake agreements and committed procurement strategies will be key to sustaining momentum.
Industry observers note that some large manufacturers are increasingly viewing diversification as reducing reliance on fossil-based feedstocks rather than simply switching suppliers. This shift could support broader adoption of alternative materials, particularly if companies prioritize resilience alongside cost considerations.
Policy direction will also play a role, with attention focused on regulations tied to batteries, raw materials, and sustainability reporting. Market participants say consistent policy frameworks and long-term procurement commitments could help accelerate adoption of fossil-free supply chain inputs while reducing exposure to future energy disruptions.
