Illegal waste dumps in the countryside: The growing criminal and environmental risk 

Cornwall and Devon’s countryside is often associated with quiet farmland, wooded valleys and a sense of distance from urban crime. Increasingly, however, that remoteness is being exploited. Beyond the familiar problem of fly-tipping, a far more serious threat is emerging in the form of concealed, large-scale illegal waste dumps. These operations go well beyond opportunistic dumping and are frequently organised, profitable and environmentally destructive. 

While small-scale fly-tipping remains a persistent issue, Cornwall Council recorded 3,655 reported incidents in 2023/24 alone, at significant cost to the public purse.  

Similar pressures are being felt across rural Devon, where local authorities and Devon and Cornwall Police have been vocal about highlighting the risks of waste criminals exploiting isolated rural land for illegal dumping. 

A growing and organised criminal problem 

Recent national investigations have identified hundreds of illegal waste sites across England, including at least 11 so-called “super sites” holding tens of thousands of tonnes of material. Cornwall features prominently in these findings, with reports of clandestine dumps containing up to 50,000 tonnes in some cases. In 2024/25, the Environment Agency shut down 743 illegal waste sites nationwide, including more than 140 classified as high risk. Despite this level of enforcement activity, over 500 illegal sites are believed to remain active. 

Although Cornwall has featured heavily in recent media coverage, enforcement agencies have made clear that waste crime is a regional issue affecting both counties. The Environment Agency has repeatedly warned landowners across Devon and Cornwall that organised waste criminals actively seek out rural land, former quarries and remote farmland to avoid detection. 

A stark local example can be found at St Newlyn East in Cornwall, where a landowner illegally imported more than 10,000 tonnes of household, demolition and hazardous waste, including asbestos, without the necessary permits. The waste was deposited in a wooded valley, polluting a watercourse in the process. Despite repeated warnings from regulators, the activity continued. 

In 2025, the landowner was convicted at Truro Crown Court under the Environmental Protection Act 1990. He received a suspended custodial sentence, was ordered to pay £16,653 in costs, and faced a £72,500 confiscation order under the Proceeds of Crime Act, designed to strip away the financial benefit gained from the offending. 

Comparable cases have also arisen in Devon, including a 2024 prosecution involving industrial-scale dumping of hazardous waste such as asbestos, resulting in custodial sentences and significant confiscation orders. These cases underline that serious waste crime is not confined to one county, but is a shared risk across the wider South West. 

Illegal waste dumping has been described in the past as “the new narcotics” due to the high profits that can be generated by charging for waste collection while avoiding landfill tax, permit fees and proper disposal costs. The proceeds are often linked to wider criminality, including money laundering, and can be used to fund organised criminal networks, making the situation far more perilous than many first realise.  

Environmental harm and risks to rural communities 

The environmental consequences of illegal dumping are severe and long-lasting. Toxic substances can leach into soil and waterways, contaminating groundwater, harming wildlife and threatening rivers and coastal ecosystems across both Cornwall and Devon. Hazardous materials such as asbestos present serious long-term health risks, while large volumes of dumped debris can block drainage and exacerbate flooding during periods of heavy rainfall. 

Rural communities are also affected in more immediate ways. Illegal dumps can blight the landscape, attract vermin, create persistent odours and, in some cases, pose a direct fire risk where waste is burned. The presence of such sites can undermine confidence in the safety and long-term stewardship of the local environment. 

The position for landowners and enforcement bodies 

The discovery of an illegal waste site can be devastating, particularly where a landowner has been targeted without their knowledge. Clean-up costs can easily exceed £40,000 and may be significantly higher depending on the nature and volume of the waste involved. There is also the risk of liability if the issue is not reported promptly. Even where individuals are victims of criminal activity, failing to act quickly or appropriately can lead to regulatory scrutiny and enforcement action. 

Enforcement agencies face considerable pressure in tackling these offences. The Environment Agency works closely with local authorities across Cornwall and Devon, as well as Devon and Cornwall Police, relying on intelligence-led investigations, covert surveillance and partnership working. Councils in both counties have deployed surveillance measures in known hotspots and can issue fixed penalty notices of up to £1,000, while the courts retain the power to impose unlimited fines and custodial sentences for serious offending. 

Early action is crucial once illegal dumping is suspected. Evidence should be recorded where it is safe to do so, sites secured to prevent further access, and the matter reported immediately to the relevant local authority or to the Environment Agency’s incident hotline on 0800 80 70 60. Businesses and individuals arranging waste disposal should always verify that carriers are properly licensed by checking the public register. Taking specialist environmental legal advice at an early stage can help mitigate risk, clarify responsibilities and demonstrate cooperation with regulators. 

Illegal waste dumping is not simply an environmental nuisance. It is a serious and organised form of criminality that exploits rural isolation and causes lasting harm to land, communities and ecosystems. Community vigilance, swift reporting and effective enforcement all play a role, but informed legal guidance remains essential in protecting the countryside across the South West, and those who live and work within it.
