A Comparative Life Cycle Assessment of T-Shirt Production Using from Viscose, Lyocell, Cotton, and Polyester

Naycari Forfora, Rhonald Ortega, Isabel Urdaneta, Ivana Azuaje et autres

This study presents the first cradle-to-gate life cycle assessment (LCA) of T-shirt production using viscose and Lyocell fibers, benchmarked against cotton and polyester under consistent system boundaries. The analysis covers spinning, knitting, wet processing, garment assembly, and regionalized energy supply. Results show …

Life cycle assessment of Brazilian bleached eucalyptus kraft pulp: Integrating bleaching processes and biogenic carbon impacts

Rhonald Ortega, Naycari Forfora, Isabel Urdaneta, Ivana Azuaje et autres

Bleached eucalyptus kraft (BEK) pulp dominates global pulp production, yet the environmental impacts of its bleaching sequences in Brazil are not fully explored. Addressing this gap, we conducted a comparative life cycle assessment (LCA) of three bleaching sequences: conventional elemental chlorine-free (ECF), …

Textiles from non-wood feedstocks: Challenges and opportunities of current and emerging fiber spinning technologies

Ryen Frazier, Mariana Lendewig, Ramón E. Vera, Keren A. Vivas et autres

As the global population continues growing, the demand for textiles also increases, putting pressure on cotton manufacturers to produce more natural fiber from this already undersupplied resource. Synthetic fibers such as polyester (PET) can be manufactured quickly and cheaply, but these petroleum-based …

An economic analysis of bamboo plantations and feedstock delivered cost in the Southern US for the manufacturing of fiber‐based bioproducts

Keren A. Vivas, Ramón E. Vera, RICHARD B. PHILLIPS, Naycari Forfora et autres

Abstract Bamboo, recognized for its rapid growth, high yield, and fiber performance is prominent in the fiber‐based bioproduct industry. However, the absence of US industrial bamboo plantations for fiber production necessitates reliance on imports or locally manufactured products using imported bamboo fibers, …
