Technologies
Sterling use bluesign® approved fibres and look for supply chain partners that prioritize sustainability
95% of the raw rope fibres at Sterling get made into finished products; remaining waste gets recycled or upcycled into non–life safety products
Rope manufacturing facility runs on 100% renewable energy
All onsite oils and cleaners are captured and disposed of properly through companies, like Clean Harbors®

Sterling offsets 100% of their carbon emissions by purchasing carbon offsets from Climate Neutral and Arbor Day Foundation
Sterling's goal is to minimise waste wherever possible. All their waste fibre is recycled, all their cardboard is repurposed, their oils and cleaners are captured and disposed of properly, and plastic bags used to protect their yarn coming in are used to protect their ropes and spools going out
