EXPLAINED: Why and how to start a zero-waste lifestyle in Germany

With zero-waste markets found in the majority of cities across the country, Germany is a good place to try embracing a reduced-waste or plastic-free lifestyle. We take a look at Germany's waste reduction efforts, and where you can shop to reduce the amount of trash you bring home.

Germany has earned a reputation for being a world leader in recycling – with a recycling rate of about 65 percent, it leads the world in preventing waste from going straight to the landfill.

That said, the average German still produces a lot of waste each year, significantly more than the average EU resident. According to Germany’s Statistics Office (Destatis), the municipal waste per inhabitant in Germany amounted to a total of 620 kilograms in 2021. The EU average per inhabitant during that year was 527 kilograms.

Why reduce waste?

Reducing waste has an impact on land use by cutting down the amount of material that needs to be sent to landfills. It also saves energy resources, because whether waste is recycled, incinerated or sent to a landfill, all of that takes energy.

Limiting your consumption of certain types of waste can also be a benefit to your health. For example, cutting down the amount of plastic-wrapped food and drinks you consume may reduce your exposure to certain toxins.

Research sponsored by the World Wildlife Fund, and conducted at The University of Newcastle, found that on average people are ingesting 5 grams of plastic each week – the equivalent of eating a credit card. 

The study also suggested that the largest source of plastic ingestion is through water. Another recent study, found that microplastic particles in bottled drinking water were 10 to 100 times more than previously estimated.

Plastics, and many of the chemical additives within them, are known to be toxic. The direct health impacts of ingesting plastics are still not well understood, but researchers tend to agree that plastic exposure isn’t advisable. 

If you’d like to limit your own exposure, reducing the amount of food and drinks you consume that are packaged in plastic is probably the best way to start.

Where you can shop to reduce waste

Buying foods in bulk, and carrying them home your own reusable containers, is a great way to start reducing waste. 

Some grocery stores in Germany, especially organic stores, offer some grains, flours and other dried items in bulk bins. There are also specialty stores, like Vom Fass, that offer oils, vinegar, liquors and other liquids on tap.

But for a more comprehensive waste-free grocery selection, seek out your local zero-waste (unverpackt) store.

Germany’s ‘zero-waste’ leader in the North

Kiel is the first German city to be called a “zero-waste” city by Zero Waste Europe

To be clear, the designation doesn’t mean that the capital of Schleswig-Holstein has entirely eliminated waste from the city. But it’s adopted a comprehensive plan to reduce waste at a municipal level.

Among the plan’s major components are a ban on single-use items at public institutions, installing more drinking fountains across the city, teaching children about waste in school, and trialling a “pay as you throw” program where people are charged only for what is thrown in their mixed waste bin.

The city’s zero-waste focus seems to have inspired individuals to launch interesting projects of their own to help reduce waste and clean things up. As reported by NDR, a former hairdresser launched a project to collect hair from salons to be used to filter oily pollution from the city’s waterways.

Individual actions add up to systemic change

Germany still has a long way to go in terms of reducing waste overall, but there are lessons to be learned from the country’s waste management efforts.

One such lesson is that positive individual actions – such as Germans’ seriousness about properly sorting and recycling waste – really adds up across a large population.

With that in mind, any additional changes you can make on a personal level are certainly worth doing. Along with buying in bulk as much as possible, carrying a reusable water bottle instead of buying plastic ones and using mesh bags for produce are both good habits for reducing waste.

Additionally, its worth making an effort to upcycle, gift, or sell items like clothes that are still have some life left. When it comes to clothing in particular, Germany has a ‘throwaway culture.’ Rather than throwing clothes out, you may want to try selling them on a second-hand exchange platform like Vinted or Kleinanzeigen. Reselling, or gifting clothes directly, tends to be a more sustainable choice than dropping them in donation bins because many ‘donated’ clothes ultimately end up in landfills.

Scientists warn poison contamination in the Baltic Sea could affect German fisheries

A team of researchers are sounding the alarm after confirming high levels of a toxic heavy metal in the Baltic Sea. Human activity, including proposed efforts to fix other environmental issues in the region could make the contamination worse.

Scientists warn poison contamination in the Baltic Sea could affect German fisheries

Scientists have warned that thallium levels in the Baltic Sea are significantly higher than previously thought.

A team of researchers from the American Woods Hole Oceanographic Institution (WHOI), confirmed that large parts of the Baltic Sea are already contaminated with the toxic heavy metal.

Their research, recently published in the Environmental Science & Technology journal, suggests that increased thallium levels in the Baltic Sea are a result of industrial activity in the region.

Thallium is considered the most toxic heavy metal for humans and animals. 

“Humans are releasing a lot of thallium into the Baltic Sea, and people should be made aware of that,” said Chadlin Ostrander, postdoctoral investigator in WHOI’s Department of Marine Chemistry and Geochemistry, in a summary of the research published by WHOI.

“If this continues…more thallium could accumulate. That would be of concern because of its toxicity,” he added.

Where does the thallium in the Baltic come from?

For now, thallium levels in Baltic seawater remain low. So you don’t need to cancel your trip to the Baltic Coast this summer.

That’s because most thallium in the Baltic is present in a layer of sulphide lying under the sand.

As long as thallium stays under the seabed in this form it remains harmless to marine life and humans, but construction work that disturbs the sea floor can release thallium isotopes into the water.

According to the research, between 20 and 60 percent of the toxic thallium that has entered the Baltic Sea in the last 80 years is due to human industry or shipping.

By analysing sediment core samples from the seafloor, the researchers determined that thallium enrichment picked up around the 1940s, suggesting its link to certain industrial activity.

“We predict, based on activities in the region, that the source of the thallium pollution is historic cement production in the region,” said senior scientist in WHOI’s Department of Marine Chemistry and Geochemistry, Colleen Hansel.

“As cement production continues to rise globally, this research could serve to caution manufacturers about the need to mitigate potential downstream effects of cement kiln dust on surrounding aquatic and marine ecosystems.”

Human impacts are creating a toxic sea

Sune Nielsen, co-author of the study and adjunct scientist in WHOI’s Department of Geology & Geophysics suggests that thallium contamination may not be the most immediate concern for the Baltic Sea ecosystem.

“As a Danish national, I follow the bad news about the Baltic in the Danish media, and our finding just adds another dimension to the already poor conditions in the basin for marine life,” Nielsen said.

An influx of farm-fertilisers and sewage-treatment discharge into the sea has resulted in the Baltic being home to seven of ten of the world’s largest known marine “dead zones”. These occur when excess algae and bacterial growth, fuelled by pollution, use up too much oxygen in the water causing fish and marine life to die off.

But human efforts to revitalise these dead zones could exacerbate thallium contamination, the researchers warn.

Current proposals to reoxygenate dead zones consist of pumping oxygen into the sea, which the researchers say would disturb sediment layers and mix thallium into the seawater where it could be absorbed by fish and enter the food chain.

“There is no doubt in my mind that it adds to the urgency of needing to do something to bring the Baltic Sea back to a state where humans and marine life can co-exist naturally,” said Nielsen.

To be clear, despite the Baltic Sea being one of the most polluted areas in the world, fish from the region are still safe to eat.

Randel Kreitsberg, a marine scientist at the University of Tartu in Estonia puts it this way in a university blog article: “The environment and the Baltic Sea are contaminated by tens of thousands of toxic substances, and even a person walking down the street is exposed to tens and hundreds of toxins…are fish from the Baltic Sea safe to eat? A short answer would be yes, they are.”

What is thallium?

Particularly toxic to mammals, thallium is a heavy metal which is not found freely in nature. 

It has previously been used in rat poisons and also as a lethal poison on people. For example, the Stasi used thallium to attempt to kill dissident Wolfgang Welsch in 1981 after he had successfully escaped East Germany.

A lethal dose of thallium for adults is around 800 milligrams, but it is easily absorbed by the body and hard to get rid of. So even small doses should be avoided.

Since 2006, the German Institute for Risk Assessment has advised that the daily intake of thallium should not exceed ten micrograms (millionth of a gram) per day. 

Commercially thallium is primarily used in the electronics industry, and to a lesser extent in the pharmaceutical and glass manufacturing industries.
