Specialised businesses under MWNW Group
Each business is hand selected for its combination of people and technology — with the ability to take an engineering challenge from concept to commercial reality.
Four specialised businesses, one engineering thread
Each business in the MWNW Group solves a different piece of the energy and sustainability challenge — from generating power in our waters to recovering value from waste. What unites them is a single engineering discipline: taking a hard problem from first concept through to commercial reality.
