What kind of waste is sorted as biowaste?

All waste that decomposes, e.g. all food leftovers, peels from fruit and vegetables, fish trimmings, solid and liquid fats (in a carton packaging). Also coffee filters, tea bags, paper towels, napkins and faded flowers are biowaste. You can also put egg cartons in the biowaste but unfortunately egg shells cause huge trouble at our biowaste management plant so we recommend to put egg shells in mixed waste (combustible waste). Dog poop, cat sand etc. is not acceptable in the biowaste.

Which bags for biowaste work in the Stormossen plant?

We recommend that biowaste is sorted into Stormossen’s paper bags, other paper bags, e.g. flour or potato bags or bags made from folded newspapers. We recommend paper bags because they decompose better than so-called bioplastic bags in the biowaste treatment process. Do not use regular plastic bags.

Why do not biodegradable plastic bags work?

There are many types of biodegradable bags and the differences are not easy to recognize. The degradeability is often tested in certain circumstances which might not occur in our biowaste treatment plant. If the bag does not fully decompose the rests will be found in our compost soil.

What alternatives do we have for sorting biowaste in a detached house?
