VITAL: Shaping Europe’s Sustainable Future

VITAL: Shaping Europe’s Sustainable Future

Europe’s manufacturing sector is at a turning point, facing growing environmental and resource pressures that demand urgent change. The transition from fossil-based to biobased and recyclable materials is no longer optional—it is a strategic necessity. The VITAL project (Innovative Processing Technologies for Biobased Foamed Thermoplastics) is driving this transition by developing breakthrough manufacturing solutions that make lightweight, durable, and recyclable foamed bioplastics viable for mainstream industrial use within a circular economy framework.

The VITAL Challenge

Despite progress in biobased polymers, their adoption remains limited. Take-up is best in the packaging sector, where compostable bioplastics have obvious advantages. However, their potential for durable applications has been largely overlooked. Barriers to date have included constrained raw material supplies, processing requirements that differ significantly from conventional plastics, and insufficient recycling infrastructure. Overcoming these challenges is crucial to integrate biobased plastics into durable, high-performance products.

VITAL’s Breakthrough Technologies

VITAL has advanced three complementary manufacturing technologies that address these barriers while ensuring energy efficiency and scalability:

1. Foam Injection Moulding of PLA

o Enables high-volume production of lightweight structural parts
o Compatible with chemical and physical blowing agents
o Intelligent control systems reduce energy use and waste

2. Low-Energy Bead Foaming of PLA & Biobased Thermoplastic Urethane (TPU)

o Replaces steam with radio-frequency heating, slashing energy demand
o Produces lightweight, cushioning, and impact-resistant foams
o Scalable for automotive, packaging, and consumer goods

3. 3D Foam Printing of PLA & Biobased TPU

o Novel print head, capable of printing polymer foam with varying densities
o Enables customized, complex geometries in rigid and flexible foams – unlocking design freedom with significant weight reductions
o Uses pellets/granulates directly, eliminating the need for filaments

These innovations are supported by overarching advances in materials development (flame-retardant PLA grades), process modelling, intelligent control, and bioplastics recycling—ensuring performance, durability, and circularity.
