No-deal Brexit could turn into a serious garbage problem in the United Kingdom.

Britain is one of the major waste exporters in the European Union sending annually more than 3 million tons of garbage to Scandinavian countries and other parts of Nothern Europe to be burnt for energy. All these agreements to export waste can expire overnight leaving millions of tons of garbage stuck in the country that doesn’t have enough capacity to process it.

If the UK won’t be able to export waste abroad after Brexit, or if Brexit makes this process less affordable because of tariffs, environmental costs borne by businesses will be hiked up along with amounts of garbage put into landfills, which is the worst way to deal with waste in terms of environmental protection.

Experts agree that the UK should rethink their waste policy that is now shaped by the European Union and build more waste-to-energy plants to close the capacity gap to avoid the crisis.
