CDE Directors, Rosemary & Tony Convery


The CDE story started in 1992, founded by Tony Convery in Northern Ireland, and since then we've grown to operate across our five strategic regions, becoming the leading provider of wet processing solutions globally, with applications across a wide range of materials within the natural materials processing, and waste recycling sectors.    

Our story began in the UK & Irish market, with the patented EvoWash™ fine sands classification system - helping our customers to maximise the efficiency of their sand washing operations through the introduction of our innovative compact washing plant. Since then, the story has continued to evolve and for over 30 years we have been co-creating with customers to deliver collaborative, imaginative and unique wet processing systems with over 2,000 successful projects commissioned worldwide.

Wet processing equipment is our sole focus. No other business can match our experience and expertise in this field. As leaders, we takes a fully consultative approach with a unique ‘Customer for Life’ business model aimed at developing long-term customers. This business model means we treat our customers’ emotions, time, and money as if they were our own, and we aim to be on hand for our customers in the long-run. 

We are relentlessly innovating with a single purpose in mind: To create our best world, a ton at a time. We create that world by prioritising our customers, people, and planet. We strive to serve people and do work that benefits our communities and the planet, all while ensuring our customers’ investments are profitable.
