Waste Management Sites

Sarah Gibson Excerpts

It is a huge pleasure to serve under your chairmanship, Dr Murrison, as I know that much of what I am going to say will be familiar to you. I thank the hon. Member for Blackpool North and Fleetwood (Lorraine Beavers) for securing this debate.

Waste facilities provide an essential public service, but communities living alongside them must not be expected to bear the consequences of weak regulation or poor waste handling. Two problems are affecting residents in my constituency: the persistent landfill gas odour around Lower Compton, and the growing fire risk over the last few years caused by lithium-ion batteries entering the household waste system.

The Environment Agency has received almost 4,000 odour reports over the last three months. As the hon. Member for Blackpool North and Fleetwood mentioned, the system is not working. Residents have described an overpowering sulphurous smell entering their homes, disrupting their sleep and preventing them from opening their windows or using their gardens. Many have reported headaches, nausea, coughing and feeling unwell. When I visited the landfill site, I was left with a headache and felt unwell for several hours. Although that is only my experience, it gives me some understanding of what the residents have been repeatedly describing.

I have pressed the Environment Agency and the operator for action, raised the issue at Prime Minister’s questions and written to the Environment Secretary. The sustained pressure has secured action for my constituents, but we now need evidence that it has actually produced results. The Environment Agency has managed to trace the principal source to an open landfill cell, requiring permanent capping, improved gas extraction and changes to the type of waste being handled. I welcome the completion of the capping works, but for residents it will be a question of whether they can breathe clean air and live normally, not whether the project is said to have been completed.

The UK Health Security Agency found no evidence of actual toxic risk, but its monitoring site is not downwind of the site—it is to the west. Although its finding is welcome, it also found strong evidence of odour annoyance and acknowledged that people may experience headaches, throat irritation, stress and sleep disruption. That exposure, although perhaps not as toxic as we expected, is not acceptable, especially for people with respiratory conditions.

The issue seems to be that responsibility is completely fragmented. The Environment Agency monitors permit compliance and the UKHSA assesses the health risk, but the local authority considers statutory nuisance. Residents are having to navigate an institutional maze while the smell continues. Will the Minister introduce a clearer joint response framework, with one lead body responsible for co-ordinating monitoring and health advice?

We also need to understand why it is happening. The Environment Agency identified an issue with the trommel fines, which can contain sulphate-bearing materials and contribute to the production of hydrogen sulphide when mixed with organic waste. Although the operators are changing the way they handle those materials, it was extremely worrying that when I asked the Environment Agency, it did not seem to be aware of where the responsibility lies for testing how much of the wrong types of material go into the trommel fines as they go into the landfill site. Will the Minister consider who is responsible for independent sampling and whether compositional controls can be better implemented?

The second issue affecting the same constituents is lithium-ion battery fires. Recent fires have, in theory, been caused by the crushing of lithium-ion batteries, which sparks a fire that is very difficult to put out. That is putting waste workers, firefighters and nearby residents at risk. The Government must start to properly enforce the existing retailer take-back duties, make return schemes more convenient and more visible, and ensure that producers meet the full cost of collection and treatment.

Finally, drawing on my 20-odd years as an architect and my experience in local government, I believe the planning system must properly assess the risk of building our homes, schools and care facilities near to waste infrastructure, as mentioned by the hon. Member for Warwick and Leamington (Matt Western). Waste sites are necessary, but communities should not be expected to tolerate unacceptable odour and risk of pollution and fire. My constituents have shown extraordinary patience, but they should not have to fight to be heard any more than those of the hon. Member for Blackpool North and Fleetwood.
