For a long time hazardous & non-hazardous wastes have been ‘co-disposed’ into landfill (ie put in the same hole in the ground).
This mixing of waste could cause long term damage to the environment and also has the potential for different types of waste to react with each other.
The Landfill Directive, which comes into force on 16 July bans co-disposal, so hazardous and non-hazardous wastes will need to be collected and disposed of separately. This is a big change the way we manage waste in the UK. The tighter controls mean positive steps to reduce risks to human health and the environment.
So what happens to it?
The following provides a simplified version of what happens to waste:
Production
Hazardous waste is produced in many ways. It might come from demolition work (producing materials such as asbestos or contaminated soils), manufacturing processes (oils or chemicals) or the disposal of consumable goods (such as used fluorescent light tubes or computer monitors).
It all requires correct disposal. Waste producers have a legal duty of care to dispose of their waste, so they need to ensure they employ properly licensed waste carriers to collect it.
Transport
Waste carriers collect wastes from waste producers and take it to waste disposal facilities. They need to ensure they advise these clients properly so they are aware of the requirements: how they need to sort their waste (what is hazardous), what will be collected, when and how.
Waste carriers also need to know which disposal sites can accept which types of hazardous waste so they can take it to the right place. Legitimate waste carriers are registered with the Environment Agency.
Disposal
The waste carrier takes waste to an appropriate waste disposal site. The most common types are landfills, but other methods include re-cycling plants, incinerators (burning) and composting. Site operators have to manage their site according to the regulations under the landfill directive and other waste regulation so must refuse to accept wastes for which they are not licensed. The Environment Agency licenses these sites and enforces these regulations

Waste management poses challenges, but could unlock major environmental and economic gains
Every day, the city of Rio de Janeiro, one of the largest metropolises in the Southern Hemisphere, generates 17,000 tonnes of waste, ranging from large industrial debris to candy wrappers bought innocently at newspaper stands. While this waste presents a serious and urgent environmental challenge, it also fuels an increasingly significant portion of the economy, with benefits extending beyond financial gains. - When we look at developed European countries, many are already recycling between 40% and 50%, with some reaching 60%. From an economic standpoint, both recyclable materials and organic waste hold tremendous value - stated Adalberto Maluf, National Secretary for Environment and Environmental Quality at the Ministry of the Environment (MMA), during the Methane Forum: Climate Emergency Brake, at the Rio Nature and Climate Week. Citing a 2025 report, Maluf mentioned that Brazil literally throws away R$27 billion annually, while municipalities spend significantly more - R$45 billion - managing all this waste, often overlooking the environmental impact or economic potential buried in landfills and dumps. - We spend R$45 billion to collect and dispose of waste in landfills, yet we manage to recycle less than a third of the potential. I believe it will be necessary to review contracts, create performance-based remuneration mechanisms, and pay for both effectively sorted materials and those diverted from landfills - he added. According to the IBGE, 60.5% of Brazilian municipalities adopt some form of selective waste collection, and several initiatives serve as examples of how to manage city waste. In his panel presentation, Bernardo Ornelas, Project Coordinator at the Rio de Janeiro Municipal Urban Cleaning Company (Comlurb), highlighted Ecoparque do Caju, a national benchmark in waste management and recycling. There, received materials are sorted and can be used for biogas production, organic compounds for urban gardens, or human consumption, in the case of still...
