Waste Strategy

We are one of New Zealand’s leading consultancies, offering specialist environmental and engineering services for the waste and recycling sector.

The management of waste is complex and needs to focus on protecting public health, environmental protection and maximising resource efficiency. Waste and resource management only becomes more complex with legislative change, community attitudes, limited landfill capacity and increasing population growth.

Our team of waste strategy specialists has the skills, experience and commitment required to help policy makers, local authorities, and the waste industry make the right decisions to optimise their approach to managing waste and materials under their control.  Our approach is based on understanding the waste sector at a practical level and a focus on real world solutions.
