Our Purpose

To innovate and deliver FRP solutions that create value for our customers and the planet, while supporting our team and our communities as we build a more sustainable future

Saving over 1 million plastic bottles from landfill every single year

By switching to rPET resin made from recycled plastic bottles, SGI Composites (formerly Sui Generis) has significantly reduced its environmental impact. In just one year, over 1-million plastic bottles are diverted from landfill or incineration and given a second life as high-performance, GRP composite products. This move not only supports a circular economy but also helps lower carbon emissions associated with virgin plastic production—demonstrating our commitment to responsible manufacturing and sustainable innovation.

Managing Director’s Sustainability Commitment

“As a proud family-owned business, we recognise that our people are the cornerstone of our success. We are committed to fostering a workplace where individuals, teams, and families can thrive, built on a culture of collaboration, fairness, and mutual respect.
