text: It looks like this place started as a group that literally took recyclables ("Solana Recyclers"), which would be tagged as amenity=recycling.
  
  Then, it sold that service to another company. Now, the place ("Solana Center") does community outreach on-site and at libraries/etc. around town to promote recycling in general, which makes me inclined to tag it as a museum (tourism=museum) or charitable organization (amenity=social_facility). However, the wiki page for amenity=social_facility doesn't look appropriate.
  
  Somewhat recently, after certain bits of legislation passed in the State of California, they're promoting themselves as a recycling and general waste consultant for local businesses.
  
  amenity=community_centre / club=enviroment_protection seems inappropriate for a group that acts as a paid consultant.
  
  So, as bizarre as it may seem, I'm going to tag it as office=ngo. As a happy accident, Nominatim should have no trouble recognizing an area marked as an office.
