Inert Waste Project

Share this page

More than 100,000 tonnes of waste is generated each year by local construction and demolition activity, excavations, and roads maintenance.

These materials - typically concrete, tarmac, bricks, stone and ceramics - are termed 'inert waste', because they do not readily react or decompose when exposed to the elements.  That makes them suitable for other uses, either within other building projects or in land reclamation.  Currently, a large proportion of this material does get reused in construction.

In future, it is proposed there will be greater emphasis on steps to reduce this waste, as well as better managing it.  A key element will are "site waste management plans", detailing how materials will be dealt with, including measures to minimise waste, and reuse or recycle them on site.  These plans are a requirement for medium and large construction projects. 

However prioritising waste reduction does not remove the need for a disposal option for some materials.  The current land reclamation site at Longue Hougue is expected to be full around 2022, after which a new solution is required. 

Progress So Far

Numerous options have been considered, from land-raising to infilling old quarries.  These were all assessed against various criteria, including practicality, capacity, value for money, potential future uses, and environmental factors and shortlisted.

This identified the preferred solution to be extending the current Longue Hougue land reclamation site to the south.  This could provide capacity for up to 15 years, and the cost would be funded from future inert waste disposal charges.

However it is also proposed to carry out further investigation of another potential option of Guillotin Quarry and L'Epine Quarry, the locations of which are indicated on the map in the downloads to the right.  

These studies will assess the various potential impacts of any potential development at each site, across a range of factors such as biodiversity, coastal processes, hydrogeology, landscape and air quality.  There will be opportunities for public consultation during this process.Once these studies are complete, the findings are expected to the presented to the States in late 2019, along with a recommendation for a preferred option.  Any development would then still be subject to a Planning Brief and Planning Inquiry, before final approval by the States. 
 

It is expected any future site would be ready by 2022
