PU foam is difficult to recycle chemically: most recycling is carried out by shredding and re-compressing mechanically. Interesting new developments from Danish researcher! https://www-plastforum-dk.translate.goog/article/view/813773/har_danske_forskere_fundet_noglen_til_effektiv_genanvendelse_af_pur?_x_tr_sl=auto&_x_tr_tl=en&_x_tr_hl=en&_x_tr_pto=nui
HydroFoamer replaces granular backfill methods. Click on ‘FASTER’ to see the video!
Simplifies trench configuration and pipeline engineering and avoids the need for almost all thrust blocks.
Pipelines are safer, with far less trench time for personnel & a vastly reduced risk of failure.
The Hydrofoamer method cuts pipeline transport infrastructure by 95% and open trench time by 75%.
