I've seen the same trend. Educational recycling content usually gets much better engagement than purely promotional posts because people like learning something practical. Simple tips, before-and-after photos, short recycling facts, or explaining the value of different scrap metals often encourage more comments and shares. In my experience, content that helps people solve a problem or understand the recycling process performs much better than posts that are just trying to sell a service. Consistency and useful information seem to make the biggest difference.
