Sustainable Glass Wool Insulation with Lignin Binder

Date:23 May 2023

Country: Austria Finland

Application

• Eco-friendly insulation: The bio-based binder replaces fossil-derived resins in glass wool, offering a sustainable alternative for thermal and acoustic insulation materials.

Description

Ursa, an Austrian manufacturer, has developed a low-carbon glass wool insulation product using a binder made from UPM Biochemicals' Biopiva lignin, a wood-based alternative to fossil-derived binders. This collaboration aims to replace synthetic resins with sustainable, bio-based materials, reducing the carbon footprint of insulation products. The new product aligns with Ursa’s commitment to sustainability and energy efficiency in construction. The innovation offers a more eco-friendly option for the insulation industry.

Pathway Description:

The process involves UPM Biochemicals producing Biopiva lignin, a wood-based binder, which is then used by Ursa to replace the traditional synthetic resins made from fossil fuels in glass wool production. Ursa integrates the lignin binder into the glass wool manufacturing process, which typically involves combining glass fibers with a binder to create the insulation material. The lignin binder is mixed with the glass fibers at specific temperatures to ensure proper bonding and insulation properties. This innovation reduces the carbon footprint of the final product while maintaining the required thermal and acoustic performance.
