2025年3月13日 · Sorema is already looking to the future by developing solutions for post-consumer films and highly contaminated packaging in the food industry. Another challenge for our technical center, which is of great interest to the market, is the combination of the deinking process with our delamination technology, which is also at the patent stage.

2024年11月5日 · To drive emerging packaging plastic de-inking, including the development of green surfactants (e.g. gamma-valerolactone), this work enables an informed chemical selection minimising potential hazards (rather than creating more adverse effects in plastic recycling processes) and toxicities from plastic waste, fulfilling the objectives of cleaner ...

2023年6月15日 · Ink removal is key towards closed-loop recycling of printed plastics. Scientific insights into the effectiveness of different deinking techniques were provided. Acid-based media are able to remove a broader range of inks. Organic solvents are particularly effective against acrylic-based polymer resins.

2021年11月11日 · "De-inking (ink removal) is a treatment by which cured ink systems are removed from a plastic substrate to allow the printed plastic packaging to be recycled and reused in the manufacturing process."

2024年8月13日 · This initiative exemplifies how collaborative efforts and updated guidelines can enable a more sustainable future in plastic recycling. Siegwerk’s advanced deinking process at their Siegburg lab marks a crucial stride in achieving high-quality recyclates and advancing circular economy objectives.

2025年3月18日 · The plant delivered was a pioneering joint project in which the plant’s deinking solution removes ink from heavily printed LDPE films, enabling them to be reprocessed into high quality recycled raw material for use in high performance film extrusion and packaging for …

2022年1月14日 · Innovative de-inking technology could lead to more recycled plastic entering the market. This could help businesses achieve cost-efficiencies and reduce the environmental burden of plastic waste. We currently produce about …

There are 10 important stages for deinking (20-22), which are described below: 1. pulpinC The various pulpers available commercially are Kneader pulper, Hydrapulper, Dynopulpers, Pulp Master, Beatapulper, Hilo pulperand Solvo pulper.

Deinking is the industrial process of removing printing ink from paperfibers of recycled paper to make deinked pulp. The key in the deinking process is the ability to detach ink from the fibers.

Deinking of post-consumer plastic waste is recognized as the preferred route to enhance circularity of printed plastic materials. To foster deinking of plastic waste and ensure technological advancements on its cooperation with recyclers and other interested stakeholders is needed.
