The transition towards a circular economy is taking shape even in the smallest details – such as a plant pot that is lightweight, biodegradable, and produced with energy efficiency in mind. This is the path taken by Osko, a German company based in Ochtrup, which is transforming horticultural packaging through a successful combination of recycled materials and advanced technology.
At the heart of this innovation is the Allrounder 720 A, a fully electric injection moulding machine by Arburg, installed in the “Ultimate+” configuration. This high-performance machine enables Osko to produce plant pots using post-consumer recycled (PCR) polypropylene (PP), derived from household plastic waste – significantly reducing the environmental footprint of its production processes.
But sustainability at Osko goes beyond recycling. The company recently introduced “Oskar”, a new type of plant pot made from PBS biopolymer – a biodegradable material that releases no microplastics and decomposes in a way similar to wood. A truly green innovation for those who embrace nature in all its forms.
Energy efficiency and consistent quality
A key element of the project is the dramatic reduction in energy consumption: just 37 kWh/h, compared to approximately 68 kWh/h for standard machines on the market – a saving of 45%. This is made possible by next-generation servo motors and a highly precise control unit.
The technology also delivers high-performance output, with injection speeds of up to 400 mm/s and pressures reaching 2,000 bar – essential for producing thin-walled plant pots quickly and with consistent quality.
Thanks to the “aXw Control RecyclatePilot” system, the machine can reliably compensate for fluctuations in the quality of recycled materials, ensuring uniform mould filling and consistent product integrity.
Fast, automated, continuous production
The production line is further enhanced by a Brink automation system, featuring a high-speed side-entry robot. The result? In just a few seconds, a four-cavity mould produces four thin-walled plant pots simultaneously, in a continuous cycle that operates 24 hours a day, five days a week. In total, 14 injection moulding machines are used in serial production – a clear demonstration of Osko’s industrial and environmental capability.
