Our History

Twenty Years Of Changing The Face Of Drilling Waste Around The World

For nearly two decades, we’ve been changing the face of drilling waste around the globe. Innovating onshore and offshore. Turning local potential into world-class talent. Leading the way when it comes to environmental standards.

TWMA started with a simple idea. Not to be the ‘Jack of all trades’, but the master of one. We saw a part of our sector we knew we could turn around. One part, where compliance could be turned into an opportunity. Where lost time could be turned into profit. Where 'waste' could be turned into value.

That’s why we are proudly focused on drilling waste management. Turning its challenges into cost-saving solutions. Turning local in-market potential into worldclass talent. Turning sketches into world-leading technology. That’s what drives our team to this day. To progress. To move forward. To never stop innovating. Perhaps that’s why today we’re trusted by the best in the oil and gas world as the waste management specialist.

A trusted partner, onshore and offshore, keeping you compliant, keeping down your costs and everyday, everywhere – keeping you turning.
