en.Wedoany.com Reported - Germany's Paderborn-based startup Palprint is developing a sustainable packaging circulation system that uses 3D printing technology to manufacture custom packaging from recycled PET. After use, these packages are almost entirely reused as raw material for new packaging. The German Federal Environmental Foundation (DBU) is providing €125,000 in funding to promote the application of 3D-printed custom packaging in industrial logistics and reduce single-use packaging waste.

DBU Secretary-General Alexander Bonde stated that well-functioning logistics is the "engine of successful business," and there is room to improve sustainability in transport, handling, and storage processes. Palprint founders Paul Lindner and Andreas Riebl-Olcze said: "We produce packaging in-house that precisely matches the respective components." They pointed out that companies often use oversized standardized packaging, which is costly and discarded after a single use. Custom packaging through 3D printing can significantly reduce such waste.

Palprint not only produces packaging on demand but also offers a system solution that includes 3D printers, software, and material supply. Riebl-Olcze stated that the company can use 3D data to automatically generate packaging and print it on-site. Palprint is collaborating with the Fraunhofer Institute to develop PET foam 3D printing, which features a 75% faster expansion rate and 90% weight reduction, while the material remains recycled PET that can be melted down and reused.

Palprint plans to establish a recycling loop, collecting used packaging and recycling it into new raw material. Lindner stated that the packaging is "almost 100% made from recycled PET," requiring no material separation and simplifying the recycling process. At the same time, transport and storage costs are reduced, and reusable packaging along with a deposit system is also being planned. These measures provide an economically viable solution for sustainable logistics through resource circulation and waste avoidance.
