National Geographic: study about plastic waste| Studie über Plastik-Abfall

Mass production of plastics, which began just six decades ago, has accelerated so rapidly that it has created 8.3 billion metric tons … 6.3 billion metric tons has become plastic waste. (Half of all plastic manufactured becomes trash in less than a year)… Of that, only nine percent has been recycled.


And this recycling can make matters even worse: In China fleece are made of disposable water bottles from Germany (as part of the recycling quota) and sold back to Germany, where they pollute the waste water and lastly the sea with micro fibers (microbeads) due to cleaning and still end up as waste, but already broken down in small particles (instead of after 450 years like the original water bottle).
Waste minimisation instead of recycling, I say!

Die Massenproduktion von Kunststoff, die erst vor 6 Jahrzehnten begann, hat sich so rasant beschleunigt, dass sie 8,3 Milliarden metrische Tonnen erschaffen hat… 6,3 Milliarden metrische Tonnen davon sind zu Müll geworden (Die Hälfte alles hergestellten Kunststoffs wird innerhalb von weniger als einem Jahr zu Abfall)…Davon sind nur 9 Prozent recycled worden.


Und dieses Recycling kann alles noch schlimmer machen: In China werden aus Einweg-Wasserflaschen aus Deutschland (als Teil der Recycling-Quote) Fleece hergestellt und wieder nach Deutschland zurück verkauft, wo sie das Abwasser und letztlich das Meer mit Mikro-Fasern (Mikroplastik) beim Waschen verschmutzen und doch wieder als Abfall enden, aber schon in kleine Teilchen zersetzt (anstatt nach 450 Jahren wie die originale Wasserflasche).
Müllvermeidung anstelle von Recycling, sage ich!

6 amazing plastic bans from around the world – and Germany? — 11. August 2016

6 amazing plastic bans from around the world – and Germany?

Good news! Plastics bans across the world have been hitting the headlines lately.From the US to India and Morocco, governing bodies are taking control of the plastic pollution problem, bringing in either complete bans on plastic, or bans on specific forms like polystyrene.

In Europe, we try to reduce the plastic waste, too, to protect the ocean from waste pollution. Especially the colorful plastic shopping bags the cashier throws at you for free. Every European uses 200 of them each year, most of them only once. But since the EU leaves it to their members how to do it, Germany uses its standard methods: personal commitment of the firms (freiwillige Selbstverpflichtung, that means they make a non-binding promise of their own to prevent a law) and money. Instead of banning these bags, the customer can use them further but in some markets he has to buy them first. Many markets offer canvas shopping bags, too, but they are more expensive. Guess what will happen?

I’m afraid it will end like with plastic bottles: instead of banning single-serving water bottles Germany put a deposit on them, just like on reusable PET bottles. And what happened? The quota of reusable water bottles decreased, of course. Many customers don’t differentiate between the two and use the lightweight single-serving bottle rather that the heavier reusable bottle, since it is all the same anyway.

Take the pledge and use no plastic shopping bags anymore – with time it becomes second nature to take your own bag with you (even if you have to interrupt the cashier in its routine to prevent getting another bag). And be proud about yourself for every disposible bag you don’t have used.

Every step counts.

Shark of the week: sofa shark — 21. March 2016

Shark of the week: sofa shark

Did you know that there is a shark called sofa shark? The false catshark (Pseudotriakis microdon) is a large (up to 9.8 ft -3 m- in length) shark that appears like a flabby brown-pink sofa. At least if you haul it on the surface.

The also referred to as dumb shark is actually a, albeit mostly sluggish, predator and scavenger in its natural environment: at depths of 1,600–4,600 ft -500–1,400 m- all over the world. Due to its large oily liver, the sofa shark is able to hover, too. It feeds on bony fish, smaller sharks and squid and, as a AT&T deep-sea shark expedition off the Canary Islands 30 years ago proved (using deep-sea longlines to find the culprits damaging their communications cables), also on our waste: the stomach of one false catshark contained “a softdrink tin, a whole pear, several boiled potatoes and a pack of cigarettes”.

The sofa shark reproduces ovoviviparous, the gestation period lasts possibly two or three years. During that time the embryos feed first off a yolk sac and later off a vast amount of unfertilized eggs provided by the mother (oophagy), but they also use them to replenish their external yolk sac (which they later transfer into an internal yolk sac to serve as a post-birth food reserve). The sofa shark gives birth to only two (maybe up to four) 3.9–4.9 ft -1.2–1.5 m- long pups at a time.

Because of the vastly different conditions especially the water pressure compared to its natural habitat, hauling deep sea fishes to the surface is not a good idea. Even after throwing them back overboard (after catching them for scientific purposes or as by-catch) they most likely die. We should let the deep seas alone.

Sources of Ocean’s Plastic Waste | Quellen der Meeres-Vermüllung — 18. December 2015

Sources of Ocean’s Plastic Waste | Quellen der Meeres-Vermüllung

Over half of the material leaked into the ocean comes from China, Indonesia, Philippines, Vietnam, and Thailand (Source). But that doesn’t mean that we others can slack off in our efforts to prevent plastic waste in the oceans – every step counts.

China, Indonesien, Vietnam, Thailand und die Philippinen sind die Quelle von mehr als der Hälfte des Plastikmülls in den Weltmeeren (Quelle). Das heißt jedoch nicht, dass wir anderen in unsere Anstrengungen, Kunststoff-Müll in den Meeren zu vermeiden, nachlässig werden dürfen – jeder Schritt zählt.

We switched back to tap water — 11. October 2015

We switched back to tap water

As I mentioned here we used bottled water. The reason was that our children got stomachache, and by trial-an-error we concluded that water from the tap was the culprit. It isn’t a new house, and we didn’t know if the piping polluted the (in Germany normally healthy and clean) tap water. So we bought bottled water, first in non-reusable bottles and later in reusable PET bottles. But after doing further research for this blog I couldn’t condone that anymore.

So we switched back to tap water. Prior to that, we made sure to clean the faucet aerators at least every fortnight, and to fill the glasses only at the tap in the kitchen (after using the first 5 liters in other ways every morning – namely boiled for tea). The children resisted a bit due to the different taste, but I explained and eased them into it by mixing with gradually less bottled water. To date, the stomachache didn’t came back (knock on wood).

I tried to persuade my husband to suggest a water dispenser for both sparkling and still water at work. But he said that wouldn’t be possible (I think he didn’t dare to ask and potentially disgruntle his boss). So he is still using sparkling bottle water, but in reusable PET bottles from a no-name local firm. Germany has got more than enough groundwater, therefore using local firms can make sure there is at least no risk to the groundwater level in other countries. But in other countries like Pakistan or the US arise big problems.

California bans even supposedly biodegradable microbeads | Kalifornien verbietet auch Mikroplastik, die angeblich biologisch abbaubar sind| Grist — 10. October 2015

California bans even supposedly biodegradable microbeads | Kalifornien verbietet auch Mikroplastik, die angeblich biologisch abbaubar sind| Grist

Other bans of microbeads contain a biodegradable loophole. California’s ban says:

We’re banning plastic beads and if industry wants to use biodegradable beads they will have to amend [the law] and the onus is on them to prove that alternative microbeads won’t be harmful, based on third-party tests.

Andere Verbote von Mikroplastik enthalten ein “biologisch abbaubar”-Schlupfloch. Kaliforniens Verbot besagt:

Wir verbieten Plastik-Kügelchen und wenn die Industrie biologisch abbaubare Kügelchen nutzen will muss sie das Gesetz ändern lassen und beweisen, dass die alternative Mikroplastik nicht schädlich ist (durch unabhängige Tests).
