# Your plant makes more than organic waste. Give the hazardous side a clear owner.

**Greenflow vs Perth Environmental**

Organic sludge and maintenance chemicals are different waste jobs. If your Ontario food plant needs a plan for chemical residues, stored drums or other hazardous material, Greenflow brings classification, pickup planning, pricing and documentation together.

## At a glance

- A defined hazardous-waste scope
- Clear pricing before pickup
- One contact through the paperwork

## Choose Greenflow to get your plant's hazardous waste handled.

Greenflow gives your chemical residues and stored hazardous material a defined service path, clear pricing and one expert through closeout. You can resolve that waste need while retaining an organic-liquid arrangement that works. Perth Environmental specializes in organic liquids, including food-processing sludge, wastewater and grease. Our hazardous-waste service starts with the separate materials your plant needs assessed and removed.

## Two different plant-waste needs

The right comparison starts with what is in the container, not simply whether it is liquid.

| Your priority | Greenflow | Perth Environmental |
| --- | --- | --- |
| Core waste focus | Hazardous-waste service built around your materials, workflow and documentation needs. | Organic liquids, including DAF sludge, grease, wastewater and biosolids. |
| Collection model | One-time cleanouts or a recurring program fitted to production. | Routine collection, cleanouts and higher-volume hauling are advertised. |
| Waste records | Manifests, reporting and service history stay organized with your accountable expert. | Perth describes traceability for its organic-waste service. |

## Why choose Greenflow

### Resolve the material your organic program does not define

An expired chemical, mixed residue or unidentified drum should not be assumed to fit a food-waste outlet. Give Greenflow the labels, quantities and available waste information. We help establish a specific next step, so the hazardous portion gets an intentional service plan instead of being treated as another tank of wastewater.

### Keep production and administration connected

Your plant team needs to know what to prepare and when it will leave; your office needs to understand the charge and retrieve the records. Greenflow connects those needs through one accountable expert. Use a one-time cleanout for accumulated material or discuss an ongoing schedule for repeat generation.

## Start with the plant's hazardous inventory

A separate, clearly defined service can solve the immediate gap.

## Your next steps

### Separate the streams on paper

List organic liquids separately from chemicals, oils and other residues. Send labels, quantities, container types and the plant address.

### Confirm Greenflow's scope

We establish accepted materials, preparation, collection timing, documentation and pricing. Any organic-liquid request is reviewed separately.

### Arrange the first removal

Approve the plan and coordinate access with production. Your contact keeps the pickup and subsequent records connected.

## Questions before you switch

### What information helps with an unidentified drum?

Send any labels, safety data, process history, estimated quantity and container details you have. Identify what is unknown so the assessment can establish the next step before a pickup is planned.

### Can cleaning chemicals go with organic wastewater?

Do not assume they can. Describe the composition and any mixing before requesting service so the material can be assessed for an appropriate handling path.

### Must I move my entire waste program?

No. Start with the hazardous scope you need handled. Existing organic-liquid service can remain a separate arrangement while you evaluate the Greenflow offer.
