Evrnu

Objective

Regenerating cotton waste to create premium, renewable fiber for apparel, home and industrial applications.

Overview

Evrnu purifies cotton garment waste, converts it to a pulp, and extrudes it as a pristine new fiber for the creation of premium textiles. Their process can create engineered fibers with a wide range deniers, shapes, and properties. The Evrnu process creates very little negative environmental impact. Pre-commercial bench scale -prototype garments produced.

Manufacturing Process

Chemical post consumer cotton recycling.

LCA available?

Preliminary LCA performed but technology is still in R&D

Water Consumption (m3/ 1000kg fiber*) or best practices used to conserve water

Minimal – bench scale achieved tens of gallons of direct water use/ kg fiber

Primary Energy Demand MJ /1000 kg fiber *

TBD (Pre-commercial). Preliminary data indicates that Evrnu pulping takes less energy than wood pulping. Fiber energy demand varies by solvent systems (ex: viscose, lyocell).

Global Warming (kg of CO2-eq/ 1000kg fiber*)

TBD (pre-commercial). Preliminary results of est. -1000 kg CO2e/ton pulp at lab scale when made with US textile waste, projected to reach -2000 kg CO2e/ton pulp.

Quality perception/ implications

Can yield higher quality fibers from low quality cotton input, with custom length, composition, and shape. Can exceed wood fibers in quality.
