In recent years, there has been a growing awareness of the environmental impact of the products we use in our daily lives. From household cleaners to industrial chemicals, consumers and businesses alike are seeking alternatives that are not only effective but also environmentally friendly. Enter biobased products and the United States Department of Agriculture (USDA) BioPreferred Program – a beacon of sustainability in the sea of traditional, petroleum-based products.

What are Biobased Products?

Biobased products are comprised of ingredients or content derived from renewable biological sources such as plants, animals and microorganisms. Unlike their petroleum-based counterparts, which are derived from finite fossil fuel reserves, biobased products offer a sustainable and eco-friendly alternative. Biobased content can be found in a wide range of products with the USDA Certified Biobased Product label, including cleaning agents, lubricants, solvents, plastics and more.

Types of Biobased Ingredients:

1. Plant-Based Ingredients: Many biobased ingredients are derived from plants such as corn, soybeans, sugarcane, palm and other agricultural crops. Examples include vegetable oils, sugars, starches and cellulose.
2. Animal-Based Ingredients: Some biobased ingredients come from animal sources, such as beeswax, lanolin (from wool) and collagen (from bones and skin).
3. Microbial-Based Ingredients: Microorganisms like bacteria, yeast and fungi can also produce biobased ingredients through fermentation processes. Examples include biosurfactants, enzymes and biopolymers.

Understanding Biobased Content

The USDA measures biobased content by “how much ‘new’ or recent organic carbon is in an object or substance, compared to the amount of ‘old’ organic carbon it contains.”

Fig. 1 Two examples of biobased content, adapted from USDA presentation.

How is Biobased Content Calculated?

The USDA calculates biobased content using a method outlined in ASTM D6866, which measures the percentage of carbon in a product derived from renewable biological sources. This method involves analyzing the ratio of radiocarbon (carbon-14) to total carbon in the product.

The higher the percentage of carbon-14, the greater the biobased content of the product. This analysis provides a quantitative measure of the amount of renewable biomass-derived carbon present in a material or product.

How is organic carbon defined?

Organic carbon refers to carbon that is bound within organic compounds, which are compounds containing carbon atoms bonded to hydrogen atoms and other elements such as oxygen, nitrogen, sulfur and phosphorus. Organic carbon is found in living organisms, as well as in decaying organic matter such as plants, animals and microorganisms.

Is organic carbon the same kind of organic as produce at the grocery store?

No, organic carbon is not the same as organic produce found at the grocery store.

Organic carbon refers to carbon that is present within organic compounds, as explained earlier. It is a scientific term used to describe the presence of carbon in molecules derived from living organisms or organic matter.

On the other hand, organic produce refers to agricultural products that are grown and produced following specific guidelines and regulations set by organic certification bodies.

Organic produce is typically cultivated without the use of synthetic pesticides, herbicides, fertilizers or genetically modified organisms (GMOs). Instead, organic farming practices focus on utilizing natural methods such as crop rotation, composting and biological pest control to maintain soil health and fertility.

While both terms involve the concept of organic matter, they refer to different contexts and industries. Organic carbon is a scientific term used in fields such as environmental science and soil chemistry, whereas organic produce pertains to the food industry and consumer products certified as meeting organic standards.

Can a product be partially biobased?

Yes, products can indeed be partially biobased. A product is considered partially biobased if it contains a mixture of biobased and non-biobased ingredients or materials. In such cases, the biobased content of the product is typically expressed as a percentage of the total content.

Partially biobased products are common in various industries, including cosmetics, cleaning products, packaging materials, textiles and construction materials. For example, a cleaning product may contain biobased surfactants derived from plant oils along with other non-biobased ingredients. Similarly, packaging materials may incorporate biobased polymers or coatings alongside conventional plastics.

Partially biobased products offer a way to harness the benefits of renewable resources while still meeting performance requirements or cost considerations. They can contribute to reducing the environmental footprint of products, decreasing dependence on fossil fuels and promoting sustainability in various sectors.

Consumers interested in supporting biobased products can look for labels or certifications indicating the biobased content of the product, such as the USDA Certified Biobased label in the United States or equivalent certifications in other regions. These labels provide transparency and assurance regarding the renewable content of the product.

What is The USDA BioPreferred Program?
