Many of the products we use every day - pharmaceuticals, cosmetics, plastic packaging, synthetic textiles, coatings and countless others - depend on modern chemical manufacturing. A significant share of the chemical feedstocks and intermediates behind them are organic compounds, with carbon forming their molecular backbone.
For decades, much of this carbon has come from fossil resources such as oil, natural gas and coal. Today, as the chemical industry moves toward lower-carbon development, reducing dependence on fossil resources has become an important part of the transition. But decarbonisation does not mean eliminating carbon itself.
If carbon is still needed, where else can it come from?
The International Energy Agency (IEA) notes that even in a chemical sector without fossil fuels, "carbon and hydrogen in its feedstock will remain a necessity, whatever their origin".
Therefore, the feedstock transition is not simply about "removing carbon", but about exploring new non-fossil carbon sources and building a more diversified feedstock system.
Exploring More Sources of Carbon
The Renewable Carbon Initiative (RCI) identifies three sources of renewable carbon: biomass, carbon capture and utilisation (CCU), and recycling. RCI describes renewable carbon as carbon that can be "(re)grown, (re)captured or (re)cycled".
These three pathways can be understood in simple terms:
Recycling keeps carbon that has already entered products and materials in circulation, rather than losing it after a single use.
CCU captures CO₂ from industrial or biogenic point sources, or from the air, and uses chemical or biological processes to convert that carbon into certain chemicals and materials.
Biomass provides renewable carbon from biological resources, including food crops, non-food crops, side streams, by-products and biogenic waste. Through further conversion, this carbon can enter chemical and material production.
These pathways do not mean that one carbon source will simply replace another. Their practical application still depends on resource availability, available conversion technologies, product performance, economics and industrialisation readiness.
For the chemical industry, this means a gradual shift from a feedstock system heavily reliant on fossil carbon toward a more diverse mix of carbon sources.
When Biomass Enters the Chemical Feedstock System
Among these emerging carbon sources, biomass is an important source of non-fossil carbon and includes resources such as crops, forestry materials, agricultural by-products and biogenic waste.
Lignocellulosic biomass, an important category within this broad group, is mainly composed of cellulose, hemicellulose and lignin. Through different conversion pathways, it can enter the production of chemicals and materials.
Corncob falls within this category and, as an agricultural residue, is also a non-food biomass resource. Non-food biomass can help reduce competition with food and feed resources, an issue also highlighted by China's Ministry of Industry and Information Technology.
But the availability of biomass alone does not make it a reliable industrial feedstock. Turning it into one still requires processing, conversion, purification, quality control and industrial scale-up, while meeting industrial requirements for stability, consistency and economic viability.
One Industrial Pathway: Corncob as a Chemical Feedstock
Within these broader developments, YINO Biologic has chosen one specific route: the industrial utilisation of corncob as a non-food biomass feedstock.
Through modern chemical conversion, corncob can be converted into furfural and derivatives such as furfuryl alcohol, and further processed into a range of bio-based furan chemicals and downstream products.
From corncob to chemicals, this pathway connects agricultural resources with chemical manufacturing. More importantly, it allows carbon originally stored in biomass to enter new molecular structures and become part of the chemical system as a non-fossil carbon input.
More Sources, More Choices for Chemical Feedstocks
The chemical industry will continue to need carbon. What is changing is where that carbon comes from.
Different carbon sources are suitable under different condition and may play complementary roles depending on resources, technology, performance and industrial demand. This also adds a new dimension to feedstock decisions: alongside performance, quality, cost and supply, companies are increasingly considering where feedstocks and their carbon come from, and whether those sources can be industrialised reliably.
From oil, natural gas and coal to biomass, recycled carbon and captured CO₂, the range of carbon sources available to the chemical industry is becoming more diverse.
The future of the chemical industry may involve rethinking not only what feedstocks we use, but also where they come from.
