Repurposing waste streams into circular economies.

Get to know our portfolio of PCC products and solutions that are dedicated to eliminating high production-related costs while reducing raw material consumption or repurposing waste streams for production. Our principles of sustainability inform our innovations, which are engineered to help improve product performance while helping to create truly circular economies.

Strengthen Performance, Reduce Costs in Paperboard. Here's how.

We help paperboard manufacturers achieve their quality and cost reduction goals and deliver solutions for a diverse range of paperboard grades.

In White-Top Liner (WTL) applications, our ALBACAR® PCC filler provides the light scattering needed to significantly improve final brightness or help balance pulp, enabling overall pulp savings and improving key WTL properties like stiffness and bulk.
Our OPACARB® and CRYSTALGLOS™ PCCs in coated board coating formulations lead to improvements in printing, brightness and smoothness, and/or reductions in coat weight and pulp costs––a gamechanger for Folding Boxboard (FBB), Liquid Packaging Board (LPB), and other coated board grades.

Our portfolio of PCC products dedicated to repurposing waste streams to give back to the planet and support sustainable economic growth.

NewYield® Technology

Our proprietary NewYield® technology converts waste streams from pulping operations into functional filler pigments, eliminating the cost of disposal while reducing raw material consumption for the production of PCC. The NewYield PCC product truly delivers excellence in performance, including improved bulk and opacity, while maintaining or improving strength and smoothness.

FulFill® technology

Our FulFill® technology portfolio is a series of high filler solutions designed to provide customers the ability to increase the amount of filler content in paper by 1-10%-points, and beyond. More filler means less dependency on fiber, and that means substantial operational savings.

ENVIROFIL® Technology

ENVIROFIL® PCC is a recycling technology that allows papermakers to recover mineral pigments from deinking residue by converting these raw materials to precipitated calcium carbonate. It replaces quicklime in PCC production by using mineral rich ash-based waste from the deinking process of recycled fibers.

Enhanced pigments & coatings.

From sought-after opacity and brightness solutions to improved filler strength and structure, explore our pigments and coatings solutions that not only improve product look and performance, but also help manage costs.

Albacar® PCC

Albacar® PCC is available in variable grades to meet a variety of customers' needs. From providing striking opacity and brightness to improving sheet strength and bulk, contact us to learn more about the right Albacar PCC for your needs.

Albaglos® PCC

Albaglos® PCC family of coating pigments offers a combination of steep particle size distribution and prismatic shape, providing superior results in paper and board coating and offset printing applications. Learn more about what solutions we have to offer.

Opacarb® PCC

Opacarb® PCCs are tailor-made to maximize fiber coverage and light scatter. From glossy to matte finishes, Opacarb PCC coating pigment provides superior brightness and opacity increases and provides excellent optical coverage while allowing coated paper and board manufacturers to reduce overall base sheet furnish costs.

Megafil® PCC

Megafil® prismatic PCC filler for paper and board acts as a functional additive and fiber substitute, offering light scattering and strengthening properties for a lustrous look and higher quality product.
