How do you keep residual flows dry and reusable, without building permanently on site?
At Hooijer Renkum, the answer was a 15-metre Kroftman shelter with topwall, placed over two concrete bunker silos.
The result: a dry, sheltered storage area that helps protect materials from rain and contamination. This keeps residual flows cleaner, easier to process and better suited for reuse.
What this delivers:
• Better protection of circular material flows
• Less contamination from rainwater
• Direct mounting on concrete walls
• No containers or permanent construction needed
A practical project for a company where circularity is part of the daily operation.
