Glass Waste, Porcelain Waste
Empty glass bottles may be disposed with the glass waste of the "Berliner Stadtreinigung" (= city cleaning service)
- The bottles have to be clean.
Mabe the cleaning of the bottles with soap and brush seems to be uncool, but it helps! Only in rare cases treatment with solvents is necessary. Lab washing machines are also OK..
- GHS-Pictograms are removed or garbled.
Removing or garbling of the pictograms is maybe also uncool but it is very necessary, because these pictograms always have to warn about an existing hazardous potential. Since you have cleaned the bottle, there is no more a hazardous potential and the pictograms must not be on the bottle just for fun.
Think about a recycling of the bottles.
- The bottle is in proper condition
- The old lable has been removed completely
... and will not be pasted over with a new lable.
- There is a proper fitting cap.
(This means: A really proper fitting cap!) Do not share in outrageous workarounds, but only recycle bottles where you exactly know the correct cap!
- All cap seals which have been present at the new bottle are still present and in proper condition.
If you do not know the kind of bottle, maybe this is diffucult to detect for you. Look for a similar bottle which is new! For example a teflon disk is no seal! This disk did nothing but protecting the cap from coming into contact with the content of the bottle until it was shipped. On using the content you poured it out and in this situation the content did come into contact with the cap. Therefore the cap might now be no more in proper condition and it is a good idea to have a stock of exchange caps.
High melting borosilicate glass (lab glassware) must not be disposed into the glass container of the "Berliner Stadtreinigung" (= city cleaning service)!
In the lab collect broken lab glass in separate puncture resistant containers. The collected glass waste has to be disposed into the household waste containers of the "Berliner Stadtreinigung".
- Only clean glass waste may be disposed in this way.
- Never put glass waste into the household waste containers found in the lab, because the cleaning staff may be harmed by splinters when they transfer the content.
- The container has to be emptied until it is not jam-packed. A jam-packed container is very hazardous, because with every agitation glass - especially pasteur pipettes may break and the plinters fly around like bullets.
- On moving and especially on emptying the container always wear safety goggles!
With contaminated glass no difference is made between bottle glass and high melting lab glass, but all waste glass is collected in a separate puncture resistant container instead. Contaminated porcelain may also be disposed into this container.
The contaminated glass has to be disposed as toxic waste. This is more expensive than to dispose clean glass. If possible and without risk think about to clean the glass waste to save money.
No foul play!
Typically with broken glass artful little "towers" may be constructed. Even in a jam-packed container it is always possible to add one more piece of broken glass. It almost seems as if the container never has to be emptied.
But if you only grab such an overfilled container you have to be aware that glass pieces will make "crack-crack-crack-crack" and the splinters will fly around with high speed. This risk is caused by sloppiness, because the container should already have been emptied whith one half of the current content.
The hero, who will take care about the problem has to ensure an excellent eye- and hand-protection. It is best to decant into a bigger container. Broom and hand brush should be at hand, because it is very sure, that after this action a lot of broken glass is spread on the floor.
