The capacity of Non-Hazardous Landfill (with and without [[SNRHW]]) has been reducing at around 18 to 20 million cubic metres per year since 2015. At this continued rate of consumption, this landfill capacity would be filled within 10 years, unless further capacity is consented/bought into operation (although the rate of consumption of Non-Hazardous Landfill with SNRHW is being consumed slightly slower). | The capacity of Non-Hazardous Landfill (with and without [[SNRHW]]) has been reducing at around 18 to 20 million cubic metres per year since 2015.

* Overall inputs between 2013 to 2018 were at 27 million tonnes+/- 1 million tonnes | |||
* 75% of the capacity for Non-Hazardous Waste in England is held at 36 sites. | |||
* Just 15 operational sites hold 50% of the capacity | |||
* At 2018 input rates, new void would be required nationally by 2024, but with significant regional variation. | |||
* This extends to 2028 with their assumptions of [[Residual Waste EFW]] coming on stream and potentially extends to 2029 and 2030 depending on future recycling scenarios | |||

The placement of waste in a landfill will slowly degrade over time, and in the case of the presence of [[Organic Waste]] within the [[Residual Waste]] going to landfill, it will breakdown to produce '''[[Landfill Gas]]''' and '''[[Leachate]]''' which have the potential to cause environmental pollution. As a result the selection of the site and the engineering and containment design to protect the environment, and specifically underlying groundwater, is critical to the successful delivery of a modern landfill. | The placement of waste in a landfill will slowly degrade over time, and in the case of the presence of [[Organic Waste]] within the [[Residual Waste]] going to landfill, it will breakdown to produce '''[[Landfill Gas]]''' and '''[[Leachate]]''' which have the potential to cause environmental pollution.
