Bioplastics Companies Struggle to Meet Demand

Brand owners are pressuring the biopolymers industry to commercialize materials and ramp up production, IDTechEx reports.
In a market growing 10% yearly, biopolymer options are at various stages of development.

As bioplastic materials transition from being a "nice-to-have" to materials with a strong and viable business case, manufacturers are racing to keep up with demand. Striving to hit their decarbonization targets by taking the initiative to transition to bioplastics, brand owners are generating a stronger pull than ever before.


However, this demand is further exacerbated by legislators around the world, who are cutting down on fossil-based plastic use with single-use plastic bans.


Together, these major factors are pressurizing players across the bioplastics industry to commercialize their materials and ramp up production. With all this activity, IDTechEx forecasts global annual bioplastics production capacity to grow at a CAGR of 10.1% over the next ten years.


IDTechEx released their latest research on bioplastics in the report Bioplastics 2023-2033: Technology, Market, Players, and Forecasts, which evaluates the technologies and trends that are bringing more sustainable biobased materials to the plastic industry. In the report, IDTechEx evaluates the technologies for polymerizing synthetic biobased polymers and extracting naturally occurring polymers. It tracks the huge industry activity that has been happening and discusses the trends and challenges surrounding bioplastics, considering these in a granular 10-year forecast.


Battle for biobased bottles

Plastic bottles are a massive fossil-based problem for drink makers. Currently, manufacturers can produce bottles made from partially biobased polyethylene terephthalate (PET), but there is no 100% biobased solution commercially available. That is because one building block of PET, terephthalic acid (TPA), remains a fossil-fuel-made material. Two options are vying to replace fossil-based TPA in plastic bottles. One is to develop a biobased TPA to get 100% biobased PET.


The other is to switch out TPA entirely for another similar but entirely biobased acid. This would make another polymer, polyethylene furanoate (PEF), which hopes to disrupt the biobased PET market as a cheaper alternative with superior properties. For now, both options have yet to produce on a commercial scale, but 100% biobased PET is close. In the new report, IDTechEx compares biobased PET and PEF and discusses the future of the plastic bottle industry.


Sustainable end-of-life options

A key factor driving companies to adopt bioplastic materials is their seemingly sustainable end-of-life processing. However, a major misconception is that all biobased plastics are biodegradable. In fact, some bioplastics cannot be biodegraded or recycled effectively. For example, polylactic acid (PLA), the most widely produced 100% biobased plastic, can be industrially composted, but this provides no nutritional value to the compost, so there are few off-takers in the industry.


Recycling PLA requires dedicated infrastructure that is uncommon and very expensive to adopt. As a result, most PLA is mismanaged or goes to landfill. Expanding the end-of-life options available is a great opportunity for PLA to grow its value as a bioplastic material. In the report, IDTechEx discusses the end-of-life options available for each bioplastic type, why some options are more valued than others, and how current bioplastic materials are being treated at the end of life.


Potential of naturally occurring bioplastics

Naturally occurring bioplastics will likely be the fastest growing segment in the years to come. Extracted directly from biological organisms, these polymers are renewable, biodegradable, and non-toxic. They are also excellent barriers of oxygen, with anti-microbial and antioxidant properties, making them ideal materials for food packaging, agriculture, and cosmetics. Despite being a young industry segment, naturally occurring bioplastic companies are forming many promising partnerships with high-profile brand-owners.
