Simply excellent and thanks for sharing

If you don't find the type of building you are looking for, don't worry, just use the next step 4 to see what others have done first
Many special buildings are actually ordinary factories.

4. Please note that this is not the end.
Please go to the workplace and subscribe to other people's successful buildings of the same type to see what special features must be added in order for them to work properly

For example, if it's a recycling factory, it doesn't produce trash (just throw the employee trash into your own machine at the end of the day).
You have to add $WASTE_DISABLE to make it happen. Maybe you want to use $HEATING_DISABLE to install a heater for your employees. The $WASTE_EXTRACTION is the waste disposal efficiency, required, so you can see what others have written.

3. Check out this Steam Guide:
https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=1885817861

or "Documentation for modders - BUILDINGS".
APPENDIX D - types of buildings

For example, if it's a recycling factory, put the types of buildings in it.
$TYPE_STORAGE
to the one you want, e.g.
$TYPE_FACTORY.
Yes, you read that right, the vanilla version of the recycling factory, is also a normal plant, except that it consumes garbage to produce recyclables.

1. Please use the game editor to build the facilities you want, but the building type is storage. Visual resource placement and so on should also be set up in advance.
Warning: After the next step 2. you can not use the game editor to edit the building (you can do so, but the building type will be forced to jump back to storage by the game editor again, and you have to repeat step 1.), so be sure to check.
It's best to build it in the game first to see if there's an error.

2. Quit the game and use the Explorer to check
Please go to:
Steam folder \SteamApps\common\SovietRepublic\media_soviet\buildingeditor
Find a folder for your new building.
Then inside the building.ini, open it with a text editor.

Hi. How did you set the garbage sorting building type in the in-game building editor? I have wanted to create my own building for a long time, but I don't know how to set the appropriate building type.

I will do my best to improve their quality, was just to busy putting them together, and i Found out some did not work so i had to go back and correct that

Welcome and well done! The building editor itself is a lot of fun.
However, it is recommended to upload more photos for each building, including daytime,
night and day, a day of construction, and other features of the building, and so on.

yes good Job.
I use this and have made a Mod for storage of Aggregates that come from Your Mod.
Here is A Link to the Mod https://steamhost.cn/steamcommunity_com/sharedfiles/filedetails/?id=3203766253&searchtext=

I confess that I felt low engagement from mod creators in creating new versions to update solid waste management. Congratulations comrade
