Perth Environmental specializes in organic liquids including food-processing sludge, wastewater and grease. Greenflow helps with the chemical residues and other accepted hazardous materials your plant needs removed. You can keep an organic-liquid service that works and give us the separate collection to assess. We'll explain what can go, what needs to be ready and the proposed price before you decide.
Greenflow vs Perth EnvironmentalCompare providers
Food waste has a collection plan. Give the old chemicals one too.
The organic-liquid pickup may be running well while maintenance chemicals and stored drums still need attention. Bring that part of your Ontario food plant's waste to Greenflow. We'll assess the materials, explain preparation and pricing, and plan collection around the work at your site.

Why choose Greenflow
Turn the stored containers into a removal plan.
Start with the labels, quantities and material information you have. Flag expired chemicals or unidentified residues rather than assuming they belong with wastewater. We'll explain what review is needed and which accepted materials the collection can include.
Fit the collection around production.
Tell us when loading areas are available and who will prepare the containers. We work through those requirements before approval, so the plant team understands the pickup and the office understands the price. Your Greenflow contact remains available for the resulting shipment records.
Add a collection for the hazardous materials
You can ask about these without changing your organic-liquid service.
Your next steps

Send details of chemicals, oils and other residues, with labels, quantities, containers and the plant address.

Questions before you switch
Must I move my entire waste program?
No. Ask us about the hazardous materials you need handled. Your existing organic-liquid service can remain separate.
What information helps with an unidentified drum?
Send labels, safety data, process history, estimated quantity and container details. Flag what's unknown so it can be reviewed before pickup is planned.
Can cleaning chemicals go with organic wastewater?
Do not assume they can. Describe the composition and any existing mixing so the material can be assessed.
BRING US THE COMPLICATED PART
Let's work through the chemicals your plant needs removed.
