The drums need to leave, the loading area has a schedule and the office needs the shipment records. Greenflow works through the job with you before pickup, giving your Ontario plant a collection plan, a clear price and a person to call about the details.

Why choose Greenflow
Give the people preparing the pickup a usable plan.
A collection involves more than a date. Container condition, loading access and work happening nearby can affect preparation. Your Greenflow expert goes through those details with you so the team getting the waste ready understands what the proposed service requires.
Keep help available after the pickup.
Operations may need to discuss a changed loading window. Later, finance may need a charge explained or a shipment record retrieved. Both can speak to the person handling your Greenflow service, with the agreed work and price as the starting point.

Will Greenflow cost less?
The quotes need to cover the same work before you can tell. We'll explain our collection price and included services so you can compare them with your current arrangement.
What should we send from the existing service?
Available waste profiles, recent shipment records and recurring reporting requirements are useful. Add the site conditions and any collection detail you want handled differently.
