Waste

The materials we use to build our homes are resources that require careful management. Our aim is to use such resources as efficiently as possible, ensuring that we limit our impact on the environment by minimising waste, and so deliver cost and efficiency savings which benefit our wider business, customers and stakeholders.

Our primary objective on every development is to prevent waste in the first instance. This is achieved through a waste management strategy that begins with the planning and design process, and filters down through the management of the construction process and across the lifetime of the development. We are also constantly evolving our house types and construction processes, seeking new systems and products to help improve the efficiency of the construction process.

Waste that is produced is then, wherever possible, segregated on-site and handled by our various waste management contractors. The vast majority is reused, recycled or, as a last resort, used as ‘refuse derived fuel’. Only a very small proportion is sent to landfill.

Summary of performance

The amount of waste sent to landfill fell by 3.7%

Tonnes of waste per home sold rose to 9.39 (2017 – 9.25)
