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 be "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 will be 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 in around 2020, after which a new solution is required.
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.
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.
If the recommendations are approved, detailed design work will begin for the Longue Hougue site, along with a comprehensive Environmental Impact Assessment. That will review of any potential impacts, including on flora and fauna, traffic and transport, air quality, and noise and vibration during construction and operation.
The site will then be the subject of a full planning inquiry, before the States is asked to give final approval. Development would be expected to start in 2021, with the site opening in 2021/22.
Members of the project team will be available to answer questions at a public drop-in session, to be held at Beau Sejour on Friday 24 November and Saturday 25 November.
