Yard teams see contamination every shift. Client teams usually see a percentage and a complaint. Bridging that gap is less about stronger adjectives and more about pairing one photo-safe example with one actionable ask.
Pick a single route or building for the note. “Citywide plastics are dirty” invites argument. “Route 4 lunch packs arrived with unfinished food in three of five sample bags this fortnight” invites a collector briefing.
Keep the ask concrete: sealed bags, no wet organics, or a reminder poster at the chute room. Utilitybloompath contamination reviews end with a one-page client sheet for exactly this purpose — figures first, then the request.
Avoid stacking five issues into one email. Recovery conversations stall when every stream sounds equally urgent. Rank by tonnage impact or rejection risk, then send the top item while the others wait for the next cycle.
