Feedstock Flexibility for Biodiesel
Feedstock Flexibility for Biodiesel
Meet enzymes, the catalysts that currently enable thirty biodiesel plants around the world to process a wide variety of waste feedstocks, providing them with the feedstock flexibility they need to remain profitable. Learn more about enzymes and their role in the biodiesel industry in our detailed eBook and find your own path to feedstock flexibility.
Embrace turmoil and benefit from feedstock flexibility

Embrace turmoil and benefit from feedstock flexibility
As the world shifts toward low-carbon fuels, biodiesel is expected to be in high demand. But the EU biodiesel market is no stranger to turmoil. Sudden rises in energy costs, the global pandemic, and growing competition have created a challenging environment for biodiesel producers in which achieving profitability has become increasingly difficult.
Thirty biodiesel producers worldwide have already committed to using enzyme catalysts to efficiently process waste feedstocks. Take your first step toward feedstock flexibility and learn more about how to achieve consistency and profitability. Follow our six-step guide to evaluate your opportunities in biodiesel.
“A gamechanger for profitability”
Over the past five years, thirty biodiesel producers have already implemented biological processing. With operations in Europe, North and South America, India, South-East Asia, China, and Africa, these plants are processing side streams and main streams of up to 100% FFA.

Feedstock flexibility is key… but at what cost?
To address these challenges, biodiesel producers are looking for solutions that they can control: what they process and how they process it.
They need to take advantage of fluctuating prices rather than falling victim to them. That means switching to the most economical feedstock available whenever required and keeping their production costs low.
Unfortunately, the cheapest feedstocks are high in free fatty acids (FFA), and he most convenient processing method for FFA is a chemical process called glycerolysis, which is expensive to set up and run. The payback period on glycerolysis is around five years—and most producers simply can’t wait that long to achieve profitability.
FAME producers' plans for feedstock flexibility
In July 2021, Argus Media, the leading energy market research company, interviewed European biodiesel producers representing 25% of EU capacity on their outlook, challenges, and strategies for feedstock flexibility in the years ahead.
- 76% plan to produce biodiesel from sources like sludge oil, animal fat, and used cooking oil
- 60% currently have limited or zero ability to process high FFA feedstocks
- 30 plants already have full flexibility
Option 1: Side stream processing
24 hours in a batch reactor tank with methanol and water at atmospheric pressure and low temperature
Produces crude FAME with 2-3% FFA and maximum 0.5% neutral oil
Biological processing of soap stock increases its value from around $100/MT as a waste product to $1,000/MT as biodiesel
Your investment is profitable after about three months
Option 2: Main stream with any feedstock
Batch or CSTR reactor with 24 hours at atmospheric pressure and low temperature
Produces FAME with FFA below 0.1% and soap below 500 ppm
Processing all feedstocks biologically produces around 200% more profit than chemical processing
Your investment is profitable after around twelve months

Novozymes: partner to the biodiesel industry
Today, more than thirty biodiesel plants around the world use enzymes to process a broad range of waste-based feedstocks including used cooking oil, palm oil mill effluent (POME), fatty acid distillates, and brown grease.
As a member of the European Waste-based & Advanced Biofuels Association (EWABA), Novozymes supports the science-based development of transport policy that evaluates technologies and energy sources with full life cycle assessment.
We were also present at EWABA's general assembly in Brussels in November 2022.
