Certified compostable ecovio® for rigid food packaging: the best combination of sustainability, functionality and design
Certified compostable ecovio® for rigid food packaging:
the best combination of sustainability, functionality and design
Packaging is the largest market segment in the plastics industry. Climate change and the future shortage of fossil resources have accelerated the search for alternative concepts to conventional plastics packaging. Approaches to reuse and recycle plastics in closed loops are developing to reach a circular economy. Certified compostable bioplastics are expanding their reach into the segment of rigid packaging for food due to the demands of converters and with brand owners driving the development of e.g. new solutions that can be organically recycled.
BASF’s certified compostable biopolymer ecovio® is a compound of biodegradable and bio-based polyesters such as PBAT (polybutylene adipate terephthalate) and PLA (polylactic acid). It can be used for a wide range of rigid packaging applications in contact with food. With ecovio®, certified compostable plastic parts can be produced on standard plastics manufacturing machines – either for fresh or dry food, with or without barrier properties, with similar mechanical properties to polypropylene (PP), high-impact polystyrene (HiPS) or acrylonitrile butadiene styrene (ABS). BASF offers grades with a range of bio-based content.
Thus, rigid packaging made of ecovio® offers the same benefits as conventional plastics packaging while having the added bonus of being certified compostable and thus supporting organics recycling:
Design freedom
Light weight
Safe transport and storage
Good carrier for printed advertising and required information

This is sustainable about ecovio® for rigid packaging
Rigid packaging made with certified compostable ecovio® has the same performance as conventional materials, but with the additional value of diverting food scraps from landfill or incineration to organics recycling: Applications that are soiled with food or organic matter after usage, can be collected in the organics bin together with the organic waste and composted in commercial or industrial composting facilities according to local infrastructure and legislation.
Thus, certified compostable ecovio® increases the collection of organic waste which helps to return valuable nutrients to the soil by closing the loop towards a circular economy for food production and consumption. Food waste is diverted from landfill and incineration, reducing greenhouse gas emissions and creating valuable compost and biogas. Compost is a valuable soil amendment as it contributes to climate resiliency: it increases the water holding capacity of soil, improves soil structure to prevent erosion and restores organic carbon to depleted topsoils.
What are suitable applications for certified compostable rigid packaging?
The recommended applications for the usage of certified compostable ecovio® are rigid packaging items in contact with food or organic matter:
• Single-serve coffee capsules
• Trays for meals and foods like sweets, meat, fruit, vegetables
• Plates, cups, pots, lids
• Cutlery, stirrers
Key benefits of ecovio® for rigid packaging
• Food contact compliant acc. to FDA (US), and European legislation
• Certified compostable according to international standards, e.g. EN 13432, ASTM D6400, AS 4736, GBT 41010
• Certified bio-based content
• Processable on conventional injection-molding and thermoforming machines
• Optimum balance of rigidity and impact resistance
• High-temperature resistant
• Odorless compared to other biopolymers on the market
• Versatile coloring
Bioplastics packaging – the next step: single-serve coffee capsules suitable for organics recycling
The mechanical recycling of conventional coffee capsules is neither effective nor economically sensible. The currently widespread multi-component systems consisting of coffee, and conventional plastic or aluminum are rarely mechanically recycled.
The weight of the average capsule consists of 80% coffee. Consumers usually do not dispose of the coffee grounds separately from the plastic or aluminum capsules - even though coffee is an excellent addition to the compost as it contains nitrogen. Thus, the valuable organic material goes to landfill or incineration.

ecovio® is a high-quality and versatile biopolymer for single-serve coffee capsules. With certified compostable capsules made of ecovio® the coffee grounds can be composted together with its packaging. Compostable coffee capsules, certified according to standards like EN 13432, will disintegrate and biodegrade in industrial composting facilities without adversely influencing the compost quality, nor leaving persistent microplastic in the compost.

Wageningen University & Research has assessed the environmental impacts and circularity of different materials for single serve coffee capsules, when subjected to various end-of-life scenarios.
Processing of ecovio® – the ideal material for rigid packaging applications
ecovio® grades for rigid packaging can be processed on standard plastic processing machines for injection molding and thermoforming. It can be used to replace conventional plastics like PP, HiPS or ABS.
Easy and precise injection molding with ecovio® IS and IA
The ecovio® injection-molding grades IS and IA are semi-crystalline plastics, which solidify in an almost amorphous state. They simplify processing also of large, dimensionally stable components. It is possible with some adjustment to achieve similar molding shrinkages longitudinally and transversely – the best prerequisites for the production of low-warp components that are subsequently fitted together.
- Suitable for thin-walled, complex designs
- Cycle times comparable to standard materials
- Noticeably increased flowability vs. other biopolymers for injection-molding
- Narrow processing window between 180°C and 210°C depending on the molding and tool equipment
