Reworld, formerly Covanta, offers coordinated collection, treatment and resource-management services with documentation. With Greenflow, your required records are part of the service discussion from the start. We review the materials and treatment requirements, explain which documents the proposed work can provide and put the collection and price in front of you. Your team can check that offer against its requirements before approving the shipment.

Why choose Greenflow
Explain the requirements before the shipment is booked.
If your customer or environmental team requires a particular treatment outcome or document, bring it into the first discussion. We'll review that requirement with the material before offering service. You can see what the proposal includes before arranging access or preparing the shipment.
Make the instructions useful on collection day.
A stored-waste cleanout and a regular production pickup may need different preparation. Tell us where the containers are, what access is available and who will prepare them. We work through the proposed collection with you, and stay available when the office needs help with the resulting records.
