Tax, Tech, and Trash: Synergies in Circular Economy Transitions

What is it about?

This study examines what actually drives European countries to recycle more: taxing waste sent to landfill or improving recycling technology. Using data from eight EU countries (Belgium, Denmark, Germany, France, Italy, the Netherlands, Austria and Sweden) from 2010 to 2024, it finds that the two work best together. A landfill tax makes dumping rubbish more expensive, but it only really increases recycling in countries whose recycling systems already turn their technology into results efficiently. Where that technology is less efficient, the tax on its own can even show a slightly negative link with recycling. Having lots of new recycling inventions doesn't help much either unless they are used effectively. The study also finds that recycling habits stick: countries that recycled well in the past tend to keep doing so, which makes it harder for those that fell behind to catch up. Finally, a high recycling rate doesn't always mean a country is using its technology efficiently. Germany recycles the most but scores low on efficiency, partly because of how the measure is built.

Why is it important?

Europe is under pressure to cut waste and meet the goals of the European Green Deal, and governments often treat taxes and technology as separate tools. This study shows that raising landfill taxes alone may not work unless countries also invest in high-performing recycling systems. Because recycling performance builds on itself over time, early and sustained investment pays off, and countries that fall behind need more support. That helps policymakers design waste policy that fits each country's situation, rather than copying one approach everywhere. It also suggests money raised from environmental taxes is most useful when it's spent on improving recycling infrastructure.
