Super fact 32: The common perception that recycling is one of the best things you can do for the environment is an exaggeration. Its impact is often not very large and if not done properly it can be counterproductive.
In general recycling is beneficial, because you conserve natural resources, reduce climate change, save energy and reduce waste and pollution. Battery recycling is particularly important since it reduces toxic waste and reduces the risk of a future shortage of certain minerals. Recycling is often viewed as a very important activity that everyone should participate in, and neighbors often shame those who fail to comply.
The shocking news is that even though recycling in general is good for the environment it may not be as beneficial as it is assumed. It turns out to be complicated. As you will see later, most people think that recycling is the most impactful action you can take as an individual to reduce carbon emissions, when in fact it is of very marginal importance. This is what made me consider this a super fact.
Recycling and Greenhouse Gases
According to EPA recycling saves 193 million metric tons of carbon emissions, which sounds a lot until you consider that the US emit 6,343 million metric tons per year according to EPA making it 3%. According to this website consumers can save 732 kilograms of CO2 assuming they do the recycling correctly. This should be compared to the average carbon footprint for an American (US), which is 16 metric tons, making the savings for good recyclers 4.6%.
According to our World in Data (Not the End of the World page 114), based on this research, giving up an average SUV for a sedan would save 3.6 metric ton, or 22.5%. Switching to a plant-based diet would save 2.2 metric ton per person, or 13.8%. Actions saving more greenhouse gases than recycling that we as consumers can take, are for example: give up SUV, go car free, have a plant-based diet, avoid transatlantic flights, buy green energy, switch to electric car, switch from electric car to no car, avoid medium flights, laundry in cold water, and hand dry clothing.
Surveys across 21,000 adults in 30 countries showed that the two actions that people believed saved the most greenhouse gases were recycling (59%) and upgrading lightbulbs (36%). Upgrading lightbulbs have an even smaller effect than recycling. It is of course still a good action to take.
However, what this data demonstrates is that we are bad at guessing which actions are impactful. We need to get better informed and not make assumptions. It should be noted that the efficiency of the recycling efforts varies from country to country. Among the 32 developed countries for which there is data the United States ranks 25.
Recycling and Plastic Waste
Greenhouse gas emissions is certainly not the only issue to consider. What about plastic waste? As it turns out plastic is very difficult to recycle (depending on the kind of plastic) and according to the EPA less than 9% of plastic is recycled. According to Our World in Data and the book “Not the End of the World” by Hannah Ritchie the US and Europe have well managed landfills and good waste management systems that make our plastic problem less of an issue. That’s good news.
But what about the awful problem with plastic in the ocean? Plastic ending up in the ocean is indeed a bad problem. However, 81% of all plastic in the ocean come from Asia, and the rest mostly comes from Latin America. Only 1% come from the United States and 1% from Europe and Oceania. According to Scientific American 93% of plastic in ocean come from just 10 rivers. Eight of them are in Asia: the Yangtze; Indus; Yellow; Hai He; Ganges; Pearl; Amur; Mekong. Two are in Africa – the Nile and the Niger.
None of them are in North America or Europe. Therefore, if we in the developed world greatly improve our recycling of plastic, it would not make much of a difference with respect to the problem of plastic in the ocean. What we need to do is assist China, India and southeast Asia with improving their waste management systems.
Another issue to keep in mind is that uneducated consumers can do a lot of damage to the recycling process. For example, throwing a greasy pizza box into the recycling bin can ruin the entire batch. You are not just recycling incorrectly you are ruining the recycling efforts of your neighbors too. There are many ways to ruin the recycling process, by throwing items in the recycling that don’t belong there. Recycling requires consumers to pay attention to the instructions. It should also be noted that some companies have been found to ignore the recycling process and throw all recycled items in with the trash. There are also neighborhoods that don’t have recycling.
Conclusion
In summary, recycling may not be as great as it is often made out to be. You should still do it if you care about the environment. Just be aware that there are actions that you can take and that your government can take that are much more impactful.
One of the conclusions you can draw from this discussion is that if you are driving a big SUV or eating red meat every day you should probably abstain from shaming your neighbor for not recycling.
