Insight: Key Trends Driving Bioplastics for Packaging
Bioplastics—plastics made partly or wholly from renewable raw materials such as cellulose, vegetable oils, and other natural substances—are deepening their reach into packaging for food and other consumer products. Behind their rise are distinct economic and market forces driving global demand for alternatives to fossil-fuel based plastics.

With packaging markets consuming more than 60% of all global bioplastics production, the packaging industry has become the most important end-use sector for bioplastics.
The growth in consumption of bioplastics for packaging is very much linked to the relative competitive prices for traditional polymers (petro-polymers), based on fossil fuel products such as oil, natural gas and derivatives. Therefore, the acceptance and growth of bioplastics in packaging is driven by the dynamics and economics of the fossil-fuel industry on a global basis.
The following are what Smithers Pira identifies as the key trends driving the market for bioplastics for packaging. An example of a package made with bioplastics is Coca-Cola’s “Plant Bottle,” which substitutes plant-based materials for petroleum derivatives in the composition of the PET plastic.
Fossil fuel costs
The increasing cost for oil, gas, and coal is not new, but what is new is the potential for economic de-linkage of fossil fuel costs as was seen in 2008. In July of 2008, oil prices spiked to over $135/barrel for the first time. Although prices have declined since, a steady-state of $100/barrel as seen in much of 2013 is not considered an attractive price range by consumers.
Furthermore, the fear of higher prices is now branded in public memory; most consumers and industries believe that costs will escalate again in the future. Bioplastics demand is directly affected by the relative competitive cost of petro-polymers, which is strongly influenced by the cost of fossil fuel feedstocks (chemicals from which other substances can be extracted or synthesized).
Although bioplastics by definition do not rely on fossil fuel raw materials, the competitive price-point for bioplastics is still very much influenced by the cost-performance of the incumbent fossil-fuel-derived polymers.
Global supply chain linkage
Today, the chemical and polymer industries are completely global, with supply agreements extending among all the major regions of the world. Therefore, fossil fuel feedstocks, as well as chemical and polymer derivatives, are traded on a global basis.
As the world’s largest supply region for low-cost fossil fuel and chemical production, the Middle East acts as the price point for determining the competitive basis for global chemical and polymer production economics.
Environmental regulations and the carbon footprint
Environmental regulations will play a role in motivating more biopolymer consumption in the longer term, especially with regards to recycling and composting. However, broad-based regulations that drive specific polymer consumption are not likely. Therefore, regulatory impact is expected to be driven less by legislation, and more by industrial and consumer perceptions.
New generation biorenewable technologies
Continued improvement in production and process technology that is used to produce building block chemicals as well as monomers, polymers, compounds and other components such as natural fibre will lead to better performance and provide economic incentives to motivate biopolymer market acceptance.
The industry expects that second and third generation cellulose conversion technology for non-food crops such as corn husks, grass and wood will soon become economic. Cellulose waste is the cheapest raw material in the biomass pool of resources, and if conversion becomes economic, it then becomes another competitive price point to beat out petro-polymer economics.
There is no doubt that future technology development will provide many new types of bioplastics for packaging and better ways of producing traditional bioplastics. These developing bioplastics will offer varying degrees of biorenewability and biodegradability. The degree to which a product is biorenewable and/or biodegradable is an important determinant for achieving market acceptance.
Overall, there are a variety of trends driving the market for bioplastics in packaging. However, it is the competitive cost and availability of fossil fuels that will have the largest impact on the commercial production and use of biopolymers.
