Our Demands

Bryn Posteg has been polluting our air and water for too long – killing streams, trapping residents in their homes, impacting local amenity use & limiting tourism. We demand change.

The landfill has been mismanaged for decades, with unaccountable operator negligence leading to inevitable and significant environmental damage. We demand accountability and .

Immediate remediation of current permit breaches

We call on NRW to immediately revoke the waste permit for the site, demand immediate action to cease all current nuisance odours, off-gassing, and water pollution.

A plan for closure and effective post-closure management

The landfill site has been so poorly mismanaged, it is no longer an effective place to store waste. But the impacts of the millions of tons of waste will continue to harm the environment for decades to come if not properly managed.
