PhD research carried out as part of the PROVIDES project has recently resulted in promising new sustainable hydrophobic Deep Eutectic Solvents (DESs). These hydrophobic DESs could successfully replace chemical solvents in the paper recycling process in order to remove transition metal ions such as iron and manganese from paper pulp.
Coordinated by ISPT, the industry-driven PROVIDES project focuses on developing environmentally friendly alternatives to chemical solvents in the European pulp and paper industry. It is financially supported by 20 industrial partners.
Deep Eutectic Solvents (DESs) are nature-based, renewable, biodegradable, low-volatile and cost-effective. When used for producing high-quality cellulose fibers in paper-making applications, they are extremely energy efficient, particularly because they do not require high temperatures. They offer a groundbreaking new method for the pulping of many different lignocellulosic materials for producing chemical pulp, pure lignin and other chemicals.

DES was the winning project of the Two Team Project, a CEPI project thanks to which the industry identified eight breakthrough technologies that would help decarbonise papermaking. Read more about it here.
