Sustainability Designed-In.

We are very conscious of the emphasis that many of our customers are now putting on circular economics and the setting of sustainability goals for, inter-alia; Energy, Electricity Consumption, Waste to Landfill and Water Consumption/Recovery.

For this reason, the solutions we provide, from initial concept to commissioning of each project, we adopt a lean six sigma approach that seeks to deliver sustainable solutions that satisfy both the circular economy and financial objectives of our customers.

Process Optimisation.

Our goal is to provide all our customers across the industrial, commercial and municipal sectors – irrespective of the complexity or scale of their challenge, with solutions which maximise efficiency and minimise operational costs. Achieving this means constant process optimisation and innovation, and application of the latest and most efficient engineering systems and solutions.

CAW has a proven track record in the deployment and operation of a range of technological solutions that enable our customer’s plants to operate more sustainably through operational efficiencies, and the recovery of valuable resources whether this be the creation of energy from waste, the recycling of products suitable for application as an agricultural fertiliser or the recovery of potable grade water from effluent streams.

The plants managed and operated by CAW include the application of some of the most advanced treatment technologies including Pasteurisation, the CAMBI Thermal Hydrolysis and the Nereda Activated Granular Sludge Technology.
