Natural gas can be obtained from organic waste. However, consumers should know what is allowed in the bio bin – and what not.
Not only remnants of fruit and vegetables, but also tea bags and coffee grounds in the filter come to the bio bin. Other kitchen waste such as egg shells and remains of food as well as old foods may also be disposed of.
You are not allowed to throw in the biotonne: everything that is not compostable. So:
Waste such as packaging made of plastic, aluminum or white sheet are properly lifted in the yellow bin or in the yellow sack. The other garbage can usually be disposed of in the residual waste.
Bio -waste can be used for gas production. For example, in a biogas plants of the Berlin city cleaning BSR microorganisms convert organic waste into bioerdgas, which is fed into the gas network. This facility was awarded by the “Germany – Land of Ideas” initiative.

The NABU has criticized that even years after the mandatory introduction of the biotonne, there are still municipalities where food residues and green waste are not collected separately. The reasons for the refusers are diverse: once it says that one has to make sure that the local incineration plant has enough fuel. Elsewhere, the separation collection is presented as too much effort in sparsely populated regions or it is claimed that the citizens are to blame because they did not properly separate the waste.
No. Neither plastic bags nor “compostable plastic bags” from corn starch may be disposed of in the bio bin. Use paper bags instead.
All objects that are incorrectly disposed of in organic waste must be sorted out extensively and affect the quality of the compost sustainably – the smallest particles always remain that cannot be filtered.

tackle against the unpleasant smell from the bio bin.
Avoid deodorants for trash cans. They are not only bad for the environment, they can also trigger headaches and nausea – allergy sufferers in particular are very sensitive to the evaporation of these aids.
