Custom Research Article
Biocomposite materials are composite materials in which at least one of the constituents is derived from natural sources. This includes composite materials made from the combination of:

  • Petroleum—derived polymers reinforced with natural fiber. 
  • Biopolymers reinforced with natural fiber.
  • Biopolymers reinforced with synthetic fiber. 
Biocomposites offer favorable attributes such as environmental friendliness, light weight, high mechanical strength, thermostability and chemical resistance. Combined with their performance-to-cost ratio, these qualities make them well suited for advanced applications, including automotive use. 

Biocomposites provide various advantages for automotive applications. As lightweight materials, they help reduce vehicle weight and lower greenhouse gas emissions. Compared with composites of nonrenewable origin, biocomposites proffer superior acoustic and thermal properties, making them suitable for vehicles’ interior parts. Their characteristics give them wide potential in the automotive sector, particularly for nonstructural interior components, including wood trim, seat fillers, seat backs, headliners, interior panels, dashboards and thermo-acoustic insulation. 

In the automotive sector, common natural reinforcements such as wood fibers can be utilized to make Wood-Plastic Composites (WPC), whereas natural fibers from flax, hemp, kenaf, jute, sisal, abaca, banana, coconut, coir, cotton, recycled fiberwood, wood, wood flour and wool can be used to develop Natural Fiber Composites (NFC).

Thermoplastic and thermosetting matrices are used in combination with these reinforcements. A variety of thermoplastic matrix options are available, including biodegradable polyesters (polylactic acid and polyhydroxybutyrate), natural polymers (cellulose and natural rubber), and commodity polymers with bio-based content (bio-polyethylene, bio-propylene and bio-polycarbonate). Multiple thermoplastic biopolymers come from the fermentation of starch and glucose. Options in terms of thermosetting matrices include standard resins with bio-based content from natural oils and bioethanol.

Increasing Adoption of Biocomposite by Automotive Manufacturers 


All leading vehicle manufacturers globally use bioplastics and bio-based plastics, including natural-fiber composites and engineering plastics reinforced with natural fibers such as flax, hemp, jute and sisal. Moreover, Ford vehicles now use eight sustainable materials, including soy foam, wheat straw, kenaf fiber, cellulose, wood, coconut fiber, rice hull and agave fibers from the tequila industry's waste. Ford announced that it will focus on eliminating single-use plastics by 2030. Furthermore, Toyota's sustainable development goals for 2050 address the challenge of establishing a recycling-based society and systems whose primary purpose is to reduce the consumption of dwindling natural resources by utilizing renewable resources and recycled materials. The goals include reducing petroleum-based plastics by developing recycled and eco-plastic technology, meeting quality and performance requirements, and establishing collection systems for used plastics. Audi announced its goal to recycle mixed automotive plastic waste in a resource-conserving, closed-loop system.

Innovations in Carbon Dioxide-based Biocomposites for Automotive


  • Carbon Dioxide-Based Sustainable Tires: Toyo Tire Corporation has developed a new catalyst to convert carbon dioxide into butadiene rubber with a high yield, eliminating the need for expensive precious metals. It was created in collaboration with the University of Toyama. The process involves the conversion of carbon dioxide to ethanol using the new catalyst, followed by the conversion of ethanol to butadiene with a zeolite catalyst.
  • Carbon Dioxide to Bioplastics Conversion using Microalgae: The University of Kentucky has researched the economic and technical difficulties of carbon dioxide capture and utilization using microalgae. A combined photobioreactor and open raceway pond cultivation system for bioplastics showed a higher algae productivity level than the conventional one. This technique is anticipated to improve the sustainability of the global plastics market by utilizing bioplastic feedstock (BPFS). This process produces BPFS rather than finished bioplastics.
  • Renewable Bioplastics from Carbon Dioxide: Researchers at Texas A&M AgriLife Extension Service are developing a two-part system that utilizes carbon dioxide to produce bioplastics. For the first unit, renewable solar power is used to convert carbon dioxide to ethanol and two other carbon molecules using a process known as electrocatalysis. Also, in the second unit, bacteria consume ethanol and carbon molecules to become a bioplastics production machine. This system operates faster and is significantly more energy-efficient compared to photosynthesis. 
  • Biohybrid System for Bioplastics with High Production Capacity: The Korea Advanced Institute of Science and Technology developed a highly scalable solution for bioplastic production that uses electricity, catalysts and bacteria. The system includes a reactor with two chambers and a separating membrane. On one side, a tin catalyst-assisted chemical reaction converts carbon dioxide gas into a formate chemical. The formate then flows through the membrane to the other side, where C. necator (bacteria) ferments it to produce granules of the PHB plastic.
