Sweden is a world leader in incinerating waste, with over 50% of its household waste converted into energy (heat and electricity) at 34 specialized plants. Other countries heavily relying on incineration include Denmark, Singapore, Japan, and66France. These nations often use "waste-to-energy" (WtE) systems, reducing landfill use to less than 1% in some cases.
Sweden has mastered the art of turning trash into treasure. With less than 1% of its waste ending up in landfills, the country incinerates approximately 50% of its household waste to generate electricity and heating for homes.
The tonnage of all types of waste incinerated in the UK nearly trebled between 2010 and 2020. Environment Agency waste data shows that there was a further increase of 12% up to 2023 in England. There has been rapid growth over the last decade in the amount of municipal waste incinerated in all parts of the UK.
Today, less than 1% of Sweden's household waste ends up in landfills. By burning trash, 52% is converted into energy, and the remaining 47% gets recycled. It's an astonishing achievement when compared to global waste averages, many developed countries still landfill more than 30% of their waste.

How does Norway dispose of waste?
While WtE plants help reduce landfill use, incineration is primarily a solution for Norway garbage disposal and plays a significant role as a district heating provider.

Sweden: turning trash into treasure
Sweden is so good at managing waste that they actually import it from other countries. Yes, you read that right. Thanks to their waste-to-energy (WtE) plants, they burn non-recyclables to generate electricity and heating. Less than 1% of Swedish waste ends up in landfills.
Over 99% of Sweden's household waste is recycled or converted into energy. Only a tiny fraction ends up in landfills. Much of the imported waste is burned in high- efficiency waste-to-energy plants, generating electricity and district heating for hundreds of thousands of homes—especially during long Nordic winters.
In this exploration of UK recycling we've learned that the UK is responsible for a massive 27.7 million tonnes of household waste each year. Of concern is the fact that, although 80% of this waste is recyclable, only 45% is actually being recycled.
Specifically in Australia, Veolia has invested heavily in an advanced high temperature incineration facility to meet the country's increasing demand for efficient disposal of hazardous streams such as medical and quarantine waste.
This shows that incineration is 80% worse than landfills for the climate, and that other pollutants that directly harm human health are 60% worse from incineration. Emissions of nitrogen oxides that trigger asthma attacks are 105 times as bad as landfills.
The UK ends up with about 50 million waste tyres (nearly 700,000 tonnes) in need of recycling every year and around half of those are exported to India - according to official figures - where they should end up in recycling plants. Before tyres leave the UK they are compressed into huge rubber cubes known as "bales".
About 79% of all plastic products end up in landfills or the natural environment (like oceans, rivers, and soil) because they aren't recycled or incinerated, with only about 9% being recycled and 12% incinerated globally, leading to widespread plastic pollution. This accumulation in landfills and nature releases harmful chemicals and microplastics, impacting ecosystems and potentially human health as they break down slowly over hundreds of years.
The most common waste-to-energy system in the United States is the mass-burn system. In this system, unprocessed MSW is burned in a large incinerator with a boiler and a generator to produce electricity. A less common type of system processes MSW to remove noncombustible materials to produce refuse-derived fuel (RDF).
Sweden has transformed its waste management into a highly profitable, circular industry, reaching a point where it must import trash to sustain its advanced energy plants. By late 2025, less than 1% of Swedish household waste was sent to landfills, with the remaining 99% either recycled or converted into energy.
China's waste-to-energy (WtE) development expansion has been meteoric. In 2000, there were just a handful of incineration plants; by 2020, that number exceeded 400 operational WtE facilities, with a capacity to process over 145 million tonnes of MSW annually (Sun et al., 2024).
Our stores have drop-off points for soft plastics, which are not widely recyclable at home. By collecting these soft plastics, we ensure they are disposed of responsibly and don't end up in landfill or the environment.
Once collected, the rubbish is transported to waste treatment facilities, which can include landfill sites, incineration plants, and recycling centres. Landfills are often the destination for non-recyclable waste, with over 70% of this waste ending up in landfills in the UK.
The cleanest country in the world is Estonia, according World Population Review's Cleanest Countries in the World 2025. The most sustainable countries include Honduras, Moldova, Norway, Sweden, New Zealand, and the UK, based on varying environmental, social and economic factors.
In Japan, there are almost no public trash cans, yet the streets are spotless. That wasn't always the plan. In the 1990s, deadly attacks used public trash bins to hide dangerous materials, so Japan removed most bins to prevent it from happening again. Instead of littering, people adapted.
As a nation, the USA generates more waste than any other nation in the world with 4.5 pounds (2.0 kg) of municipal solid waste (MSW) per person per day, fifty five percent of which is contributed as residential garbage.
Plastic waste is one of many types of wastes that take too long to decompose. Normally, plastic items can take up to 1000 years to decompose in landfills.
The UK does not commonly use garbage disposals due to plumbing regulations and environmental concerns. Many homes also lack compatible plumbing systems. Garbage disposals are widespread in the US, but not in the UK.
About 50% of Costa Rica's population. Considered the most contaminated river basin in the country. The river's watershed drains approximately 67% of Costa Rica's untreated organic and industrial waste . Called "one of the most polluted waterways in the country".
