Applications for bioplastics

Today, bioplastics can be found in the following market segments:

  • Packaging
  • Food-services
  • Agriculture/horticulture
  • Consumer electronics
  • Automotive
  • Consumer goods and household appliances


There is a high demand for packaging made from bioplastics to be used for wrapping organic food as well as for premium and branded products with particular requirements. In 2018, global production capacities of bioplastics amounted to about 2.11 million tonnes with almost 65 percent (1.2 million tonnes) of the volume destined for the packaging market – the biggest market segment within the bioplastics industry.

Rigid bioplastics applications are available for cosmetics packaging of creams and lipsticks as well as beverage bottles and many more. Materials such as PLA, bio-PE or bio-PET are used in this section. Several well-known brands such as Coca-Cola, Vittel, Volvic or Heinz use bio-PET for bottles of all sizes containing drinks and other fluids. Procter & Gamble and Johnson & Johnson resort to bio-PE to package different kinds of cosmetic products. As a potentially mechanically recyclable material, PLA is also gaining pace in the rigid packaging market.

Biodegradability is a feature often sought when it comes to food packaging for perishables. Flexible packaging solutions such as films and trays are particularly suitable for fresh produce such as fruit and vegetables as they enable longer shelf life. The requirements for food packaging are as divers and numerous as there are different types of food. Today, packaging materials and processes are extremely sophisticated and easily adaptable to meet specific application and preservation needs. When it comes to protecting food and prolonging shelf life the performance of bioplastics packaging is at least comparable with existing conventional packaging and sometimes even better. By continuing to improve barrier properties like antimicrobial coating and other aspects, the bioplastics industry will be able to achieve better preservation of food products than current packaging very soon.

For almost every conventional plastic material and application there is a bioplastics alternative available on the market that has the same properties and potentially offers additional advantages.

Eating and drinking on the go is part of modern lifestyle. This is also linked to the requirement for flexible packaging solutions. In Germany, for example, the market volume in the catering sector, including among others plastic silverware and crockery, paper and cups, amounts to roughly 3.5 billion Euros. In the last ten years, this market has grown on average by seven percent each year. As a result, there is (and must be) a broad spectrum of bioplastics products available for the food and catering segment. The selection ranges from cups, mugs and trays to plates and cutlery.

Agriculture and horticulture
Biodegradable polymers offer specific advantages in agriculture and horticulture. Mulching films – the most important example – are generally making rapid advances in these sectors: production of pure foods with a minimum use of pesticide is a powerful sales argument in vegetable-growing or organic farming. Ploughing-in of mulching films after use instead of collecting them from the field, cleaning off the soil and returning them for recycling, is practical and improves the economics of the operation. Biodegradable mulching films today are very well adapted to the location and fruit.

Other promising applications in agriculture and horticulture include: films for banana bushes, which have to be protected from dust and environmental influences; fastening technology; plant pots for propagation/cultivation; fertiliser rods; or pheromone traps, which no longer have to be removed after use.

Biodegradable plastics also offer opportunities for pot-plant marketing. Herb pots are a good example. Once the herbs are harvested, everything including the film can be composted. Alternatively, products can simply be planted into their pot, which is very convenient for hobby gardeners. Flower bulbs that can directly be planted into the soil in their packaging are also available. The packaging disperses quickly and then plant growth can begin.

Consumer electronics
A large proportion of consumer electrical appliances are made of plastics. Today, casings, circuit boards and data storage are made of plastic to ensure the appliances are light and mobile whilst being tough and, where necessary, durable. An increasing range of bioplastic products is introduced in the fast-moving consumer electronics sector: touch screen computer casings, loud speakers, keyboard elements, mobile casings, vacuum cleaners or a mouse for a laptop.

In the automotive industry manufacturers have turned to biobased or partly biobased durable bioplastics to produce sturdy dashboard components as well as solid interior and exterior features. Components made completely or partially from bioplastics can provide a standard of safety that is of ultimate importance in the transportation sector. The products include seat and airbag covers as well as steering wheels.

With new innovations on the way, bioplastics will take up a greater share of the composition of both automobiles and high-quality, fast-moving consumer electronics.
