I have set up 2 composters in my garden, the green one I started already last year and the metal one was set up this year. Since I don't want to throw away the garden waste and the green waste leftovers from my fruits and vegetables I set up 2 composters to produce some nice compost of all the green materials that are growing in my garden and that I throw away, like cut grass leaves and weeds.
One of the composters the green one I already started last year in summer so some of the material is already rotten quite a bit but it sill needs a little bit more time to turn into soil that I will be using to grow some vegetables in my garden. This way I can use the circular economy to save some CO2 by composting the leftovers myself instead of bringing it to a facility. The other benefit is that I will soon be harvesting some really nice compost / soil from this process.

Since one composter is a bit to less for most of my garden waste and the organic waste that I produce in my kitchen (which is only a very small fraction of the garden waste). I put up the second composter with only 4 stainless steel grids in my garden. I am already looking forward harvesting some of the nice compost soil next year or in the next 2 years depending on how fast the material dissolves into compost soil. For the bigger meaterial I have bought a shredder to shred the bigger parts into small parts so they dissolve and compost faster this way. With this 2 different kinds of composters I will also have some comparison between these 2 models. The open one which is only 4 grids and the more closed one that is made from plastic.
Usually it is good to have a great mixture of differnt green and brown materials on the composter so the decomposition will work faster, but I have made a different approach and still try to mix some greens with browns. My intention is to have the green composter as my main composter for all the kitchen fruits and vegetables, since it is right outside the kitchen, and the metall composter is mainly used for all the grass and weeds and leaves and plants that are growing in my garden that I want to get rid of. This is some kind of convenience for me since I don't want to have such a long distance from the kitchen.

A lot of insects like invertibrates and worms live in my compost and help me to decompose the material I throw in there. There will not be any extra CO2 generated like when I put the waste into the "Grüne Tonne" which is a way a lot of poeple threat their green waste by giving it to a facility that is composting their material. But this material has to be transported to the facility that will produce some extra CO2 in this process. And of course I will not need to buy so much soil that will help me save money and also I don't need some extra CO2 by driving my car to bring the soil to my garden. Another benefit for me is that this kind of producing compost soil is also much cheaper than buying it somewhere.
Composting is a core pillar of the circular economy, transforming organic waste into nutrient-rich soil amendments, reducing landfill use, and cutting greenhouse gas emissions. By cycling nutrients back into the soil, composting improves soil health, sequesters carbon, and replaces synthetic fertilizers. It supports sustainability by closing nutrient loops

My second composter is at the edge of my property hiding under a bush and tree so it is usually not visible in my garden. Picture: Florian Glechner.
