Customized Hemp Pulp Extraction via Laccase–Pectinase Pretreatment for Improved Waste Pulp Papermaking

Abstract The reuse of waste pulp presents a sustainable alternative to petroleum-based polymers in packaging, contributing to the mitigation of environmental and resource-related challenges and fostering sustainable development. Repeated reuse of waste pulp significantly deteriorates the fiber structure, which adversely affects vital performance metrics such as tensile strength. In response to this challenge, we introduce a sustainable and energy-efficient strategy for fabricating tailored hemp pulp, designed to be incorporated into recycled waste pulp to enhance papermaking properties.
