How the Brazilian government buys waste collection
Household waste collection, street sweeping, final disposal, and collection of healthcare waste. These are long, high-value contracts, measured per ton or per kilometer. They require an environmental license for the operator and proven disposal in a licensed landfill — inspectors follow the waste transport manifest.
What the tender notice usually requires
- Environmental operating license
- Disposal in a licensed landfill
- Compatible fleet
- Waste transport manifest
Typical activity code (CNAE): 38.11-4 (collection of non-hazardous waste). Make sure the company's registered
business purpose covers the activity before bidding — an incompatible CNAE is grounds for disqualification.
How to prepare to bid in Piauí
Follow new publications daily: between the notice and the bid deadline there are usually about eight business
days, and much of that time goes into gathering documents. Download the tender notice and the terms of reference
from each tender page, check the specification item by item and work out your minimum price before the bidding
phase — including taxes, freight, payment terms and the margin that makes the contract viable.
Micro and small businesses (ME/EPP) get preferential treatment under Brazilian law: a tie preference, extra time
to fix tax certificates and, in smaller purchases, exclusive participation. See the step-by-step guide
how to participate in a tender.
