Mineral-oil-free inks achieve top INGEDE deinkability certification
Toyochem Specialty Chemical’s “TK MARK V” MOF (Mineral Oil Free) ink series secures the highest “Good” rating from the International Association of the Deinking Industry (INGEDE), highlighting its recyclability and compliance with stringent sustainability standards.
Toyochem Specialty Chemical Sdn. Bhd., part of Japan’s artience Group, has announced that its “TK MARK V” MOF series of mineral-oil-free (MOF) sheetfed offset inks has achieved the highest rating of “Good” in the deinkability assessment conducted by the International Association of the Deinking Industry (INGEDE). The certification was granted after testing print samples on coated glossy art paper under INGEDE Method 11, which evaluates the ink’s removal performance during recycling processes.
The ink series demonstrated outstanding results across all major parameters, including exceptional luminosity, effective colour removal, minimal dirt speck areas, and stable brightness difference. These findings confirm that paper printed with “TK MARK V” MOF inks can be recycled efficiently, ensuring high-quality pulp recovery suitable for producing paper products that match the standards of virgin fibres.
Reading tip: Sustainability of Coatings
Explore the future of environmentally responsible coatings with the must-have resource, Sustainability of Coatings. This essential guide dives into the ecological impact of coatings throughout their life cycle, offering formulation chemists, R&D specialists, and industry leaders actionable strategies for improving sustainability. Packed with insights on circular economy principles, CO₂ footprint analysis, and emission reduction techniques, this book is an invaluable tool for designing resource-efficient and recyclable coatings.
Key role of deinkability in paper recycling
Deinkability is pivotal in removing ink and non-fibrous contaminants from recycled paper to create clean, reusable pulp. This process helps prevent contamination during recycling and supports the production of high-grade paper products. As regulatory frameworks, such as the EU’s Packaging and Packaging Waste Regulation, increasingly prioritise recyclability and environmental impact reduction, deinkability has become a crucial factor in ink selection.
Haruhiko Akutsu, Chairman of Toyochem Specialty Chemical, stated, “The certification confirms the “TK MARK V” MOF series’ ability to support clean fibre recovery while meeting stringent environmental and regulatory expectations. This achievement reflects our commitment to developing products that facilitate circular material flows and align with sustainable production goals.”
The certification aligns with the artience Group’s Sustainability Vision 2050/2030, which aims to ensure all products are either low-impact or circular-economy ready by 2050. Toyochem’s success with the “TK MARK V” MOF inks underscores the company’s dedication to advancing sustainable solutions in the printing industry.
