Knowaste update: Our plans for new site Hayes 180

In the last edition of the Knowaste newsletter we unveiled plans to develop the UK’s largest nappy recycling facility in Hayes, West London.

Knowaste at Hayes 180 is an ambitious project that will position the borough of Hillingdon as a leader in waste management and environmental sustainability. This supports the West London Waste Plan, which sets out planning policies for the management of waste with a view to reduce the five million tonnes of refuse generated by the area each year. We estimate that our new site will handle at least 36,000 tonnes of AHP waste a year, helping the area reduce waste and reach its ambitious aims. 

On the planning side, our Change of Use planning application for the recycling of Absorbent Hygiene Products (AHPs), like nappies, was submitted late August. We have recently been informed that Hillingdon Council will determine the outcome of our application at a Major Applications Committee   early 2016.

For a waste management project of this scale, it is common practice for a planning application to be determined by committee. We are hopeful for a positive outcome and look forward to going to committee to demonstrate the benefits that Knowaste will bring to West London. 

In November, we also submitted an application for an environmental permit to the Environmental Agency (EA) which is an operational permit to regulate the facility. Our application was duly made by the EA on 8th December which means this is ready to be assessed and we’re expecting a response in the next few months. 

On the engineering side, we’ve been working with Haden Freeman Ltd, engineering design consultants based in Manchester, who have helped us shape a Front End Engineering Design (FEED) to assess the costs and help us plan for our new site. The study is entirely flexible and can be adapted to our future sites in the UK and abroad. You can read more on Haden Freeman’s involvement here.

With an investment to the tune of £14m, Hayes 180 will be the biggest plant of its kind in the UK. It is part of a larger programme of site development that we plan to roll out across the UK within the next five years.
