RPR offers lab packing, chemical relocation, storage, auditing and training, with customized project proposals. Greenflow helps you work through the laboratory waste you need removed: what is known about the materials, what preparation is required and how collection would fit the site. We explain the work we can provide before approval, with one contact for the pickup and the records after the lab reopens.
Clear the chemical backlog with the work agreed before shutdown.
A term break or lab shutdown is a chance to deal with old chemicals, but preparation matters. Greenflow starts with the inventory you have, works through acceptance and collection requirements, and explains the proposed price. Your Ontario lab gets a plan to review before committing its work window.

Why choose Greenflow
Start with the inventory you actually have.
Old labels, partial lists and containers of uncertain condition are reasons to begin the conversation, not to guess. Tell us what is known and flag the gaps. We'll explain the next review step before agreeing to collection, including which preparation tasks need to be resolved.
Keep the clearance separate from a lab move.
Removing unwanted chemicals and relocating materials you still use are different jobs. Tell us which work you need, who is packing the waste and whether other contractors are involved. Your proposal will identify what Greenflow can provide, so the lab team can prepare for the agreed collection.
Plan the clearance around your lab
Share the inventory and work window before arranging collection.
Your next steps
Send the available details
Include names, labels, photos, quantities, container condition and existing records. Flag unknown materials and access restrictions.
Review preparation and price
We'll explain accepted materials, preparation and the proposed price. Identify who will handle packing and any further assessment before agreeing to pickup.
Arrange removal
Agree the collection with your Greenflow contact. Use the same contact for manifests, reporting and billing questions afterward.
Questions before you switch
What should we do with unidentified containers?
Flag them in your inquiry and share the available records. They need review before a handling plan can be offered.
Does a collection quote include moving the laboratory?
Not automatically. Tell us if you need a lab move as well as waste removal; the proposal will specify the work we can provide.
Can we plan the clearance during a term break or shutdown?
Tell us the dates when the lab is available. We'll review timing, materials and access before offering collection.
Make a plan for the chemicals your lab no longer needs.
Send the available inventory and work window. We'll work through the materials, preparation, collection and pricing with you.
